AUTOMATIC BUTTER-DISPENSING APPARATUS.

Specification of Letters Patent.-

Application filed September 5, 1912. Serial No. 718,785

T 0 all'whom it may concern Be it known that I, EDWIN M. LARSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Automatic Butter-Dispensing Apparatus, of which the following is a specification.

This invention relates more particularly to a sanitary machine by means of which chips of butter such as are used in restaurants and hotels may be automatically cut from bars and ejected into butter plates thereby eliminating the necessity heretofore of handling the butter chips by hand during the preparation of the same for table use.

An object of this invention is to provide a machine to be operated by waiters or other attendants in restaurants, hotels or other eati ng places whereby chips of butter will be dispensed individually and automatically and without handling, so that the waiter or other attendant by placing the individual butter dish in position to receive the chip and then operating the machine will deliver a butter chip of the appropriate size onto the butter plate so that it may be taken directly from the bar of butter to the guest or customer in perfect sanitary condition.

An object of this invention is to provide a novel unitary machine which willv automatically guide a body of material such as a bar of butter into positlon, cut rectangular parallel sided chips from such body and eject'the out portions into plates.

I regard this invention as pioneer, being the first machine which may be charged with one or more bars of butter and then when operated will at every operation without further attention, out a chip of butter and eject the same into the receiving butter plate so long as the charge is not exhausted.

Further objects of this invention are simplicity, compactness, ease and convenience of charging, large capacity, convenient and proper refrigeration, and invariable appropriate performance of the necessary operations at the proper times.

It is necessary that thebutter shall be kept at a proper temperature, so that it will out properly without breaking or mashing and provision is made whereby such temperature 1S readily maintained.

Other objects and advantages of thisinvention may appearfrom the subjoined de-' tail description. if I Variouschanges of construction may be made without departing from the invention or some of the'features thereof. v 7

Referring to the drawings, the invention comprises a combination of mechanisms which will be considered in the following order: mechanism A, for cutting the loutter; mechanism B, for automatically stopping the cutter centrally between the cutting strokes; mechanism C,'for ejecting the butter chips; mechanism D, for connecting the cutter and ejector actuating mechanism with the butter bar advancing mechanism; mechanism E, for advancing the butter bar; mechanism F, for supporting the butter bars and moving them successively into position for cooperation with the butter bar advancing mechanism; and mechanism G, for regulating the thickness of the butter chips.

. This invention includes said mechanisms and the said combination and also various parts and combinations of parts that will be more fully set forth in tail description.

The apparatus shown is designed to be actuated by the oscillations of an operatingleft at the Provision is also handle, which moves right and front of the machine. made for automatically dropping the butter bar supporting tray after the same is emptied and provision is also made whereby access to the interior of the case may be had conveniently from the front to remove the empty trays and to reach the internal mechanism.

- The accompanying drawings illustrate the invention, Figure 1 being on a reduced scale and the other figures-on a larger scale. Fig. l is a front elevation of an automatic butter dispensing apparatus embodying this 1113611131011, also showing a dish in position to receive a butter chip. Dotted lines indicate hidden portions, solid lines show parts in normal stationary pos1t1on,.and dot and dash lines indicate positions assumed by said parts at thev beginning of the right ejecting stroke. The guard is broken away to expose certain parts that would otherwise be hidden. Fig. 2 is a fragmental'plan section on a larger scale common to all the views except Fig. l and viewed from ir-- regular line 05 Figs. 1,'3 and 7; and is illustrative of the mechanisms A", B and C. Pa-rts are shown in the chip-ejecting position correspondingpractically to the posi- P tented Nov. 9, 1915.

the subjoined detion shown in solid lines in Figs. 3 and Fig. 3 is a fragmental front elevation. further illustrating the mechanisms A, B and C. Solid lines show the chip-ejecting posi tion corresponding to the position shown in solid lines in Fig. 7 and just following that indicated in dot and dash lines in Fig. 1. Broken lines indicate the position of parts after the return of the cutter at the com pletion of the right-hand cutting stroke, while dot and dash lines indicate normal rest position of parts. Fig. a is a view analogous to 3, showing in solid lines the position assumed by parts at the beginning of the left-ejecting stroke. Dot and dash lines indicate the position of parts at the completion of the left ejecting stroke and also at the beginning of the operation to advance the plunger. Fig. 5 is a view analogous to Figs. 3 and a: showing a position assumed by the parts as the cutter is nearly back to its normal central position and the plunger actuating arms is about to drop to cause the actuating mechanism E, (see Fi 15%, 15, 16, 17) to advance the Hunger. ijhe 'uard is omitted from Fl 's.

Solid lines show the retracted position of the plunger agreeing with Fig. 15, and the eX- tended latch about to return to the normal holding position. Fig. 10 is a fragmental mid-sectional elevation on line as -a1 Figs. 9 and 1-1. F ig. 11 is a fragmental broken transverse sectional elevation viewed from. irregular line at, Figs 9, 10 and 14:, showing parts in the position corresponding to Fig. 9. Solid lines illustrate a position of parts at a step in the butter-lowering operation. Dot and dash lines indicate the normal stationary position from which parts have moved to said position shown in solid lines. Fig. 12 is a fragmental broken transverse section viewed from irregular line 00 Figs. 7, 8, 9, 10, 1 and 15, looking toward the front of the machine. Parts are broken away for clearness of illustration and are in the chip-ejecting position shown in Figs. 3. 7 and 11. Fig. 18 is perspective detail of one of the butter containers viewed from the under side thereof. Fig. 1a. is a broken plan section looking down from the back of the machine. The section is on irregular line :W-m, Figs. 1, 3, 7,12, 15 and 16. Parts are shown in the chipejecting position shown in solid lines in Figs. 3 and 7. Broken lines indicate difierent positions of the butter chip as it drops to the dish. Parts are broken away for clearness of illustration. Fig. 15 is a fragmental broken longitudinal section viewed from irregular line 425 x, Figs. 3, 9, 12 and 1%, looking in the opposite direction from that of Figs. 7 and 8, illustrating the mechanism E. T he parts are shown in the position they assume when the plunger has just retracted and a full tray of butter has replaced the empty tray that has dropped to the bottom of the machine preparatory to being removed. Fig. 16 is a view analogous to Fig. 15 showing parts in the position they assume when the cutter and ejector are about to perform final operation before the plunger is retracted to the position shown in Fig. 15. The ice chest and drip pan are omitted from this view. Fig. 17 is a frag-- mental mid-section analogous to Figs. 7 and 8 illustrating the mechanism G. In this view the parts are adjusted. to cut butter chips twice as thick as those out by the machine in the previous views. Parts are in the position they assume when the plunger has just been released and is about to retract to the position shown in Fig. 15. The guard is omitted. Fig, 18 is a fragmental broken elevation viewed from itregular line .90 Fig. 17 and is analogous to the right fragmental portion of Fig. 8. Parts are shown adjusted to secure greater between the panels 3 on a vertical axis; the

intermediate section or member 5 being hinged on a horizontal axis at its lower edge and capable of being swung down and out to permit easy access tothe interior, and being provided with a guard 6 detachably mounted above and in front. of a central front opening 7 therethrough which com municates with the interior of the case for the ejection of the butter chips.

Inside the case there is provided a space for an ice chest 8 having legs 9 to hold a supply of ice in the upper rear portion of the case to cool the case and its contents, including the charge of material to be chipped and dispensed and also the mechanism hereinafter described for supporting moving, holding and cutting said material, as the butter bars 10 andlO, The bottom of the ice chest 8 is provided with holes a, (see Figs. 14-, and 17,) through which water from the melting ice may drip into a bifurcated pan 11 that rests upon the floor 12; said pan being provided with a faucet 13 preferably at the front of the machine to drain the pan as the ice melts. The pan is bifurcated so as to fit into the case at the rear and on both sides of the mechanismcarrying frame which will be hereinafter fully described.

The guard 6 is in the form of a hood fitting over the opening through which the chips are to be ejected and extending below said opening and open at the bottom only considerably below the bottom of the, said opening through which the chips are to be ejected, so that the cold air will be conserved in the machine.

Butter-cutting mechanism A.The butter bars 10. 10 are carried by the bar holders comprising trays 10 supported by suitable means hereinafter described and adapted to successively hold their respective bars in cutting position behind the central opening 7 through which the chips areto be ejected.

The butter-cutting mechanism A is carried by the hinged intermediate section 5 and comprises a horizontal transverse slide 14 having an orifice 15 therethrough "and mounted to reciprocate transversely of the machine in top and bottom guides 16 carried by and forming part of the intermediate which is hinged at the bottom on.

section 0 a horizontal axis 17 and is held normally up-- right in closed position by the latch 18 engaging a portion of the frame 1 at the front of the case. On the inner face of said slide is mounted the cutter means, preferably in the form of an individual filose cutter 19, being preferably a single wire, extending vertically across the open space 15 of the slide 14; and being detachably secured inplace by suitable means such as studs 20 fixed to the slide above and below the orifice 15, said wire being passed through holes 21, adjacent the edges of the orifice and wrapped around said studs and'stretched taut and clamped against the slide by nuts 22 screwed home upon the studs to firmly hold the wire. i

The'transverse slide 14% is provided at one side with a vertical slot 23 transverse the slide, through which slot extends the pin 24 of a} crank arm 25 that is between theintermediate member and the slide and is fixed upon one end of a stub shaft 26 which extends through and is journaled to the intermediate member 5 and is operatable'a half turn at a time'by a crank lever 39 outside the case. The crank pin it fits the slot which is in parallelism with the. filose cutter and is equal in length to the diameter of the path of the crank pin so that a complete cycle of the slide is effected at each full revolution of the pin.

By openingthe intermediate section 5 the butter-cutting mechanism may be dropped down out of the way as indicated in dot and dash lines in Fig. 7 thus giving free access to the interior of the case from side to side across its front. 7

The slide 14: is arranged to normally stand at rest'with the filose cutter in a vertical plane centrally of the opening 7 so that vwhenever the butter bar is moved forward while the slide is in its normal position of rest the bar will be slit along its vertical mid-plane by thefilose cutter. The mechanism which operates the slide is constructed and arranged as hereinafter described to alternately'move the slide from its central position of rest to one side and back to rest and then vice versa, from the point of rest to the other side and back to rest; that is to say, the filose cutter normally stands at rest stationar filose cutter 19 at thealternate' restings of the cutter, so that at eachad Vance of the bar a longitudinalslit 27 will be cut in the bar along the verticaliaxial plane of the bar, so that the portion 28 projecting forwardly from the holder will be cut off from. the bar in the form. of two chips that are severed at separate strokes independentlv of each other by reason of the alternate movements of the cutter from rest to the sides in first one and then the other direction one movement of the cutter forming the chip in Figs. 7 and i l and the other movement forming the chip 30 in Fig. 4.

Ivlounted upon the front of the hinged intermediate section at each side of the opening 7 are slotted slides 31 provided with abutments adapted to extend into said opening 7 in position to support the sides of the forwardly projecting portion of the butter bar thereby affording gripping means to hold the forwardly proportion 28 of the butter bar against (llSplflCQHlQlltunder pressure of the filose cutter 19. The abut-ments 32 are adjustably secured in place upon the member 5 by means of screws 33 extendin through slots in said abutments and screwing into said member The filose cutter is adjacent to the abutments being fastened just far enor h ba k to be out of alinement with the edges of the same.

The stub shaft 26 (see Figs. 1% and 1 to 5) is fixed by pin at its inner end to the crank and is mounted in a bearing 35 ixed to and projecting from the front of he hinged member 5; and upon the outer end of said shaft there is secured by pin 26 a collar 36 provided with two oppositelyarranged ratchet teeth 37 adapted to be alternately engaged by a spring-controlled pawl 38 carried by the operating crank lever that hand operated in the direction of the solid curved arrows in Figs. 3 and and is returned, in the direction of the broken curved arrow in said Fig. 3, by a spring 40 that is fixed at one end to the hinged section and is coiled around the bearing inside the housing or crank drum .1 and secured at the other end to the crank lever 39 (see the dotted construction in Fig. 2) to return it to rest position against a stop 1 6 whenever the crank lever is released after being operated to turn the crank 25 to move the slide in either direction. The ratchet roller 12 in the pocket 43 prevents backwarc rotation of the shaft 26 and crank The bars to be cut are twice as wide as they are thick and to cut them into squares of any desired thickness it is only necessary to move the filose cutter from and to its central station alternately right and left each stroke from and return to rest serving to sever a chip of a thickness determined by the depth to which the cutter enters the bar when the bar is advanced.

Mechanism B.-The mechanism B for au arm at the end of the return stroke of v the operating cranklever 39 as said lever returns to normal upright position against .the I stop pin 46 as shown in Fig. 1; the rock: shaft 4'? to which said arm is fixed being journaled in the member 5 and operatively connected inside said member with two 0scillating bars 4:3, e9, that are connected together by a connecting rod 50, moves said bars simultaneously in reverse directions; the

bar being fixed near one end to the rock shaft f? and provided with a stop face 51 at the end of its long arm, and pivoted at the short arm by a pivot 52 to the connecting rod 50, while the lower oscillating bar 1-9 is provided with a stop face 53 almost vertically below the stop fa e 51 and facing in the direction opposite thereto. lhe pin connecting the rod to the lower bar e9 is between the stop. face 53 and the pin which pivots said lower bar tothe inter.-

mediate section and the pins 52 and 5d are equidistant from the centers on which said bars oscillate, while the faces 51 and 53 are practically equidistant from such centers, so tl at when the rock shaft 17 is operated the stop faces are moved up: and down practically the same distancethough in reverse directions.

T he weight of the rock shaft arm 4:5 and oscillating bar e3 overbalances that of the oscillating arm l9 and connecting rod 50,. so that when the rock shaft arm s5 is unsupported. by the cam the stop face 53' is raised into the way of the pin 24- in its movement from right to left in Fig. 1 and the stop face 51 is lowered into the path of said pin as it moves from left to, right. Consequently by this means when the operating crank lever 39 is fully depressed to the dash line position shown in Fig. 3 the pin 24. engages the lower stop face 53, thus stopping the operating crank lever 39 which is thereupon returned by the spring 40V to. the stop 46 at which point the rock shaft arm is again lifted by the cam at, so that at the next right movement of the operating crank lever: the crank pin 2% is allowed to move onward; and. as it moves, the cam H is again withdrawn from the rock shaft arm 45 whereupon the weight of the overbalancing parts drops the stop face51 into the way of the crank pin 24: which is there. by stopped when the crank pin reaches the position vertically above that at which it was stopped by the face 53. It is thus seen that at each full right movement and d epression of the operating crank lever, the slide is moved to carry the filose cutter from mid-position to one side and return to. midposition; the normal stoppage of the slide and the cutter it carries always occurring at the mid-position. i

t is to be noted that the means for relatively moving the cutter and the butter bar are so constructed as to constitute, in each instance, means to cause relative direct, nonpivotal movement between the cutter and the butter bar, thus to form the usual butter chips having parallel fiat sides.

Mechanism C.The mechanism C for ejecting the butter chips is illustrated in Figs. 1,2, 3, l, 5, 7, 15, 16 and 17. The ejector comprises a sleeve 56 having an actuating pin and ejecting finger 66 that is slidably and rotatively mounted between stops57, 58 upon a guide-rod 59' that is carried by the intermediate section 5 and that extends parallel with and adjacent tothe slide l l; said guide-rod being preferably mounted in said stops which are fixed to the front of the hinged intermediate front section 5. Ejector actuating tappets 60, 61

provided with downwardly diverging faces 62, 62 and horizontal slots 63 are fixed to the slide by screws ea passing through" said slots and, when the screws are loosened, are adjustable toward and from each other along the slides. The actuating pin 65 extends between the faces 62, 62, and a spring 67 in the form of a spiral loop is bent around the ejector sleeve, one loop end of the spring being under the actuating pin 65and the other loop end resting against the slide 14, so that the upward pressure of the spring on the pin retracts the ejecting finger. Said spring yieldingly holds the vertical tip 68 of the ejecting linger in a vertical transverse plane that extends just in front of the filose cutter. As the slide 14 moves to the right the tappet face 62 engages the actuating pin 65 and slides the ejector along the rod 59 until the end of the ejector sleeve 56 impinges against the block 58, which thereupon holds the ejector against further lateral movement while the oblique tappet face 62 continues to move to the right thereby forcing the actuating pin down and overcoming the resistance of the spring 69 and throwing the ejecting finger and the tip 68 forward. The result of this operation is that the ejecting tip 68 runs along the top of the rear side of the butter chip just in front of the filose cutter until said chip is severed and then said tip moves outward to eject the chip. On the return movement of the sleeve toward the left the ejector slide remains momentarily stationary on the guide-rod 59, while the filose cutter passes the ejector tip. When the tappet face 62 has receded from the actuating finger the spring 69 returns the ejector tip to its retracted position, and then the tappet face 62 engages said pin and slides the ejector along the guide rod behind the filose cutter; and upon the next actuation of theslide the thus directing the chip forwardly toward' the butter plate 70 which is placed centrally under the guard 6 upon an extension of the floor 71 that forms the butter plate shelf. 7

The timing of the ejecting mechanism with relation to the cutting mechanism may be accomplished by the adjustment of the slotted tappets transversely along the slide .14 upon their screws 6a.

Mechanisms D, E, F andGr are mounted inside the case upon the frame 72 that is fixed to the floor and to the front portion of the frame of the case by screws 72, and that comprises two front and two rear standards 73, 74c and top and bottom braces 75. i i

211' echam'sm D.Th e mechanism D for connecting the cutter and ejector actuating mechanism with thebutter bar advancing mechanism comprises a rigid rock-shaft arm 76, arranged in operable relation to the crank-pin 2i, and mounted on a rock-shaft 77 that is journaled to the front and rear standards 73, 74: and that isconnected by an arm 78 and a connecting rod 79 with one end ofa pivoted lever 80 that is pivotally mounted at 81 upon the rear extension 82 of the frame 72; the other end of said lever 80 being connected by a connecting rod 83 with a ratchet arm 84c that is journaled on a transverse driving shaft 85 and is provided with a spring-pressed driving pawl 86 which engages a ratchet wheel 87 fixed on said shaft to turn the shaft the space of one or more notches of the'ratchet wheel at each complete revolution of the crank-pin 2 The spring-pressed locking pawl 88 pivoted at 89, underneath the ratchet-wheel 87, to the extension 82 prevents back movement ofthe ratchet wheel.

As the rockshaft arm 76 is operated by the crank-pin 2a the pawl 86 is retracted from the ratchet wheel, and in order to drive the pawl 86 and the butter bar advancing To this end lost motion connecting means are provided whereby the spring 90 may be compressed at a determined period as the crank-pin 2i actuates the rock-shaft arm '1' 6, and which connecting means under the action of the spring will suddenly actuate the pawl 86. Said means comprise the driving lever 91 fulcrumed at 92 to the framevextension below the lever 80 and provided with a roller 93 between the fulcrum 92 and the point at the end of the lever 91 on which the spiral spring 90 acts through the knifeedge bearing '93; said spring being held in place by a spring holder formed by a rod 9-1 run through the bearing and the spring, and a tension nut 95 on said holder.

It will be seen by reference to Figs. 7 and 8 that on the upstroke of the connecting rod 7 9, the pawl 86 is retracted and as the roller 93 is acted on by the lever 80 the free end of the lever 91 arid the washer 93 are raised thereby compressing the spring 90; and that as soon as the crank-pin 2%. has passed the rock shaft arm 76 the spring 90 at once acts to operate the lever 91 and the pawl is thereby advanced to drive the ratchet wheel and rotate the driving shaft.

The lower portion of the spring holder 9% is curved in an are described from the fulcrum 92 of the lever 91 so that the end of said lever may run freely up and down said guide to compress the actuating spring and to respond thereto.

The driving shaft is connected to drive the mechanism hlfor advancing the butter bar.

Mechanism E.The mechanism E for advancing the butter bar comprises a mutilated gear 96 fixed to theshaft 85 and engaging a rack 97 fixed. to the plunger '98 having the adjustable butter "advancing plates '99, 99 mounted at the forward end. thereof and separated by 'a narrow open space forming a cutter-way 100 to allow the plates to pass one step beyond the filose cutter after the last chips have been scraped from the plates and ejected from the machine. The toothed segment 101 of the mutilated gear 96 is of suilicient length to move the slide forward its full length at each revolution of the inntilated gear to carry the 'baradvancing plates one step beyond the filose cutter; and the blank segment 102 of said gear 96 is of suflicient length to disengage the rack and allow it to run freely back at the end of each revolution of the gear.

The butter moving plunger 93 is mounted in a horizontal guideway 103 provided with a standard 104v to support the rear end of the plunger retracting spiral spring 105, the front end of which is connected by a standard 106 with the slide.

The locking. pawl 88 is constantly in position to prevent back movement of the ratchet wheel driving shaft 85 and the mutilated gear '96; and it is necessary that the Inntilated gear shall not be allowed to revolve forward during the retractionof the bar advancing rack 97. 'With this end in view a latch 107 is pivoted to the frame extension S2-and is operated by a spring 108 to engage a catch in the form of a pin 109 that projects from the mutilated gear in position to engage the latch shoulder 110 when the blank segment 102 of the mutilated gear is adjacent to the rack 97, so that at that time the mutilated gear is held from back action by the ioc'king pawl 88 and from forward when by the latch 10?.

A tripper in the form oi a pin 111 fixed to the rack, projects into the way of the latch 107 to retract said latch from the catch pin when the rack is fully retracted. A rack starter in the form of a finger 112 fixed to and revolving with the mutilatedge'ar extends to engage the starting shoulder 113 on the rack, when the tripper has released the latch sothat on the next forward r movement of the pawl 86 the rack will be advanced to engage the toothed segment 101. The machine is intended to chip, in succession, a number of butter bars; and with the object of allowing the siic'c'e'ssive bars to be fed vertically, pro ision is made whereby the butter-advancing plunger shall be supported wholly by 'means outside the space either above or below the butter bar carrier. Vltll this object in view the slide-way 114 of the frame extension is extended rearwardly the full length of the plunger, and is slotted longitudinally with parallel side slots 115 and an intermediate t'oo'thedslot 116. On the slide-way list is mounted an auxiliary slide 117 on which is mounted the plunger slide 118 that carries the rack and is provided with parallel slide slots 119 and an intermediate toothed slot 120. The teeth 121 of the intermediate slot 116 are on one side of their slot, and teeth 122 of the slot 120 are on the other side of their slot, and a stub shaft 123 is journaled in the aiiXiliary slide 117 and is provided at its opposite ends with pinions-124, 125 to engage the teeth of the intermediate slots respectively, so that as the plunger slide is advanced, the auxiliary slide is advanced at half the speed, and vice versa; thus opera-ting to keep the auxiliary slide on the guide to support the plunger slide when it is moved into the way of the butter bars. A

v Retaining blocks 126 are fitted to the auxiliary slide and run in the slots 115 in which they are dovetailed to hold the auxiliary slide inplace on the slide-way. "Other 'retaining blocks 127 are in like manner fastened to the auxiliary slide and dove-tailed in the slots of the plunger "slide.

7 By this construction the plunger is capae 'ble of forward extension the full length of thebiitter bar and 'isyet firmly supported by the rear extension oht'he frame which does not project into the way of the butter bar or the carrier therefor. V

The guide bar 12? fixed to the rear frame extension extends over the edge of the plunger slide to hold it from drooping as it is shoved forward.

Mechanism F.The mechanism F for supporting the bars of butter and moving them successively into position for cooperation with the butter bar advancing plunger comprises four bracket carrying sprocket chains 12S mounted in pairs on pairs of sprocket wheels 129, 129 on opposite sides of the butter bar way 130. The brackets 131 on said chains are arranged at intervals apart somewhat greater than the thickness of the butter bars to be chipped, and butterbar supporting trays are provided according to the number of superposed butter bars that can be accommodated at one time in the butter way. The upper sprocket wheels 129 are mounted on driving shafts 133 that are journaled to the frame 72 and said shafts are connected by gearing 13%, 135, 136, 137 to rotate at the same speed, said gearing being fixed to the frame 72. The lower sprocket wheels 12-9 on one side of the frame are fixed on a shaft 138 that is journaled to said frame, and an escapement wheel 139 provided at intervals on one side with teeth 140 is fixed to the end of said shaft. An escapement lever 141 is pivoted at 142 to the bracket 113 on the rear frame extension and is normally held by the spring 144 in the way of said teeth to support the escapement wheel against the weight upon the brackets. The upper end of the escapement lever 141 is provided with a. front oblique face 1 15 extending into the way of a tappet 146 that is pivoted to the plunger slide and is held by a spring 145 against the forward stop M8 on said slide, so that when the plunger returns on its backward stroke the tappet will engage the escapement lever and momentarily withdraw it from the tooth of the escapement wheel with which it is engaged and allow the load of the brackets to move the sprocket chain and wheels, thus lowering the empty tray out of the way and the next tray above into position with the butter bar alined with the plunger and central opening 7. The escapement lever is normally held oblique to the plane of the escapement wheel, so that when its upper limb is in position to intercept a tooth its lower limb is withdrawn from the way of the teeth; and said lever is arranged in a common plane with a lower chord of the escapenient wneel. The escapement teeth arebevcled on their ascending faces to engage the underside of the lower end of the lever should said lever fail to return to its normal position by the action of the spring l fe after being withdrawn by the tappet 1 6, thereby to insure swinging the lever to move its upper end into the way of The teeth are spaced on the escapement wheel a distance apart sufiicient to allow the sprocket'chain to more the space between two brackets, so that when the escapement lever is thrown off to release a tooth, its upper limb is immediately returned at the close of the backward stroke of the tappet by the spring 1 14 into the path of the next tooth. Consequently, whenever the escapement lever is tripped by its tappet, the butter bars and their supporting trays are allowed to descend just far enough to bring the lower most butter bar into the way of the plunger. I

The brackets are arranged on the sprocket chains in such position relativeto the operating parts that when the sprocket chain is stopped a set of brackets are in position to support the butter bar and tray on a level with the filose cutter and the opening 7 through the intermediate hinged section of the case,'so that the butter bar will be supported in the path of the plunger ready to be forced through said opening as the plungeris advanced step by step.

The butter bar holder 10 comprises a tray 149 formed of a plate having ears 150 bent up at its rear end to hold the rear end of the bar. and provided with butter bar guides 151 at the front end to direct the bar into thepath of the filose cutter. Said guides are adjustable being provided underneath the plate with arms 152 pivoted to the plate at 153, 153 and provided at their ends to readily pass between the lips Mechanism G.The mechanism (z for regulating the thickness of the butter chips comprises means for changing the position of the rock shaft arm 76 and for this purpose a movable bearing 155 is slidably mounted on one of the upright front standards 73 and is provided with a portion 156 to engage the under side of the arm 76. A pawl 15'? provided with a handle 15? is pivoted to the bar and adapted to engage a shoulder formed on the standard 73 to support the arm-engaging por ion lfifiin an elevated position to hold the arm 'TG'aslant at one angle. By withd awing the paw down the standard until. caught by the supporting hook 155, thereby allowing the rock shaft arm 76 to drop to a different angle with the path of the crank-pin 2a. When the rock shaft arm is supported in its upper position the crank shaft escapes from the arm after moving the arm through a limited arc, but when the rock shaft arm is un supported by said portion, the crank pin 2% will reach said earlier and move it through a greater arc. l he action of the driving pawl 88 is proportionately greater or less, depending on whether the rock shaft arm 76 is supported at the lower or upper position.

In the machine illustrated there are fiftythree teeth in the driving ratchet wheel 87 so that when the rock shaft operates the driving pawl 86 only one notch at a time, the bar will be cut into fifty-two transverse slices of two chips each, and the fifty-third tooth will operate to move the plunger forward one step beyond the position where the filose cutter was when the last chip was released This additional step is necessary in order to advance the plunger to a point where the rack is free from the mutilated gear; and when this point is reached, the spiral retracting spring 105 immediately retracts the plunger; and the escapement being released on the return of the plunger, the inner limbs of the sprocket chains are allowed to descend, thus bringing a new butter bar into position in front of the plunger and dropping the empty butter bar tray to the floor of the machine from whence it may be removed by opening the lower door 159 in the front of the machine.

When it is desired to increase the thickness of the butter chips the hearing 155 is lowered, so that the rock shaft arm 7:) will be moved twice the arc in which it was pre viously moved; and when thus adjusted the driving pawl is retracted two notches instead of one at each operation of the rock shaft and on its return by the spring 90 the lever 91 will operate the driving pawl through the space occupied by two ratchet teeth, thus turning the mutilated gear twice as far as before andt-hereby advancing the plunger a like distance.

When the plunger has been advanced to the filose cutter it is desirable that the next step which releases the plunger rack from the mutilated gear shall only equal the space between the fifty-third tooth and the one immediately followin and to allow the ma chine to be fully adjusted to make the thicker chips, an adjustable runner 160 is pivoted to the ratchet wheel 87 and clamped thereto by the slot and screw connection 161, 162 see Fig. 17) so that by fixing the runner in place to close the space between the first two teeth the pawl is supported against dropping therebetween.

The operation of the apparatus will be understood. from the foregoing. The apparatus may be charged with butter bars by opening the front door l and inserting the trays onto the brackets and placing the butter bars on the trays. The butterbars may be stored in the ice ch ,st, the top of the case being removable for that purpose, and the o erator will use his judgment as to how many butter bars will be placed in the machine at a time, it being preferable to leave the butter bar and its tray in the ice chest until the demand for it arises, but it is understood that where the demand will be rapid, a larger number of trays with butter bars thereon will be placed on the brackets than when the demand is expected to be limited. When the machine is thus charged, the plunger, being fully retracted, the waiterwill place a butter plate centrally on the shelf 71 and will thenoperate the crank lever twice, thus bringing the lilose cutter to a stop centrally in front of the butter bar and advancing the butter bar at the close of the second movement toslit it by forcing its end past the filose cutter. At the next movement of the crank l ver a chip will be cut and ejected onto the butter plate. If: two chips are desired, the crank will be operated again, thus depositing another chip on the butter plate. At the end of this movement, the plunger is kicked forward by the actuating spring 90, As the work goes on the plunger is advanced after each second cutting until the last chip is ejected and the plunger rack has reached the open segment of the mutilated gear, whereupon the retracting spring retracts the plunger and the tripper 14:6 actuates the escaping lever thus releasing the escapeinent wheel and allowing the weight of the butter bars on the sprocket chains to more said sprocket chains, thus withdrawing the lower brackets from the empty tray and allowing such tray to drop to the floor and the next filled tray to go into position on a level with the filose cutter, after which the operation proceeds as hereinbefor described.

If it is found in case of very hard butter that the spring 90 does not act with sufficient force to drive the butter bar so as to cut it with the filose cutter, the tension of said spring may be increased by screwing down the tension nut 95, and vice versa; the nut will be loosened if the butter bar is softer.
