MACHINE FOR vIeILILIIlNTG- BOXES'.

4To all whom t 'may concern: y

Be it known that I, MICHAEL PARIDoN, a

citizen of the United States, and resident of v Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Machines for Filling Boxes, of which the following is a specication.

- This invention relates to machines for lilling match boXes, more especially the trayand-shuck form of box.

The invention particularly though not veX- clusively concerns certain improvements in the automatic match-box filling machine illustrated in Letters Patent of the United States No. 1,064,452, dated June 10, 1913. 4In that machine the boxes are deposited upon an endless chain conveyer and thereby impelled consecutively to and past the delivery end of the match machine, beingthus supplied with matches. The lled trays are carried to and between t'wo conveyers, one of which, termed a plunger-conveyer, bears a series of plungers, and the other of which,

termed a .shuck-conveyer, carries the.-

match shucks or slides for the trays. The

lplung'ers are successively reciprocated during their travel adjacent the `filled trays, so as to push the opposing trays from the trayconveyer and insert them into the complementaryshucks on the adjacent shuck-conveyer, all as will onore fully appear by reference to said Letters Patent. f

The obj ect of my invention is to provide a machine of the character mentioned whereby a uniform and rapid feedin and delivery'of the matches to the matchox trays is attained; whereby the efficiency ofthe mechanism for positioning the empty trays and their complementary shucks or covers in relation to each other is increased, and whereby the filled trays are accurately and positively entered in their shucks or covers.

Accordingly the invention comprises various features of construction and combinations of parts which will be hereinafter described and claimed.

In the drawings- Figure'l is a side elevation of a match-box filling machine embodying apreferred form Specification of Letters Patent.

Referring to the drawings, 20 designates an elongated hopper to one end of which matches are delivered from a suitable source of supply, as, for example,'the endless match carrier of a continuous match. machine; a part of which carrier is indicated by dotted lines at 21 in Fig. 1.- The form of hopper illustrated comprises an inclined bottom 22 having two parallel sides 23 providing between them a space slightly greater in width than the length of a match. The lower ends of the sides are horizontally extended, as at 24, and their outer extremities are connected by a transverse end plate 25 which is appropriately recessed on its lower edge, as at 26, for the free passage of traveling blade devices which will be hereinafter described. The side extensions and the adjacent part of the bottom overhang a horizontal bed or table 27 which is supported by the standards of a suitable supporting frame 28. The bottom is provided wi-th a suitably-disposed slide 29 which is mounted on a guidepiece 30 on the table, so as to permit longitudinal vibration of the hopper. The bottom is also provided with depending lugs 31 which embrace an eccentric carried by a shaft 32 which is driven in any suitable manner, so as to eiect the rapid bodily vibration of the hopper and thus insure the feeding of the matches therealong from its upper to its lower or discharging end. (See Fig. 1).

A The lower end of the hopper-bottom is provided With a'longitudinal opening or slot for the free passage into and from the hopper of the traveling blade devices above referred to. The inner portion 33 of this opening is of less width than the length of a match, and hence, while the matches in the adjacent part of the hopper are supported at their ends, access can be had to the matches .throu h the opening.

row. The row of blades 35 is adapted to receive and carry match trays (37), and the row of blades 36 is adapted to receive and carry the complementary shucks or covers (38) for the trays. The conveyer chain passes about wide' sprocket wheels 39, 40 mounted on transverse shafts 41, 42, having their bearings in brackets beneath the table near its respective ends, the upper horizontal run of the chain traveling upon the top of the table and the lower run upon the longitudinal guide rail y43 supported by posts 44 on the main frame. Each ofthe shafts 41, 42 bears at one end a pin' Wheel 45 with the successive pins 46 of which engages a Worm wheel 47 on a power-driven main shaft 48 extending longitudinally of and having its bearings in boxes in the main frame. The contour of the worm wheel and the coperative relation of the parts are such that the endless conveyer is continuously driven. but yet slows down at the suc cessive points wherethe trays and shucks are applied thereto, so as to facilitate the entrance of the trays and shucks to the conveyer as will presently appear. The location of this conveyer relatively to the hopper is such that in thetravel of the conveyor about the wheel 40 to a horizontal position, the reduced upper extensions 35 of the blades 35 successively enter the slotted portion of the hopper bottom and separate and select an approximately measured quantity of the opposing mass of matches; thence as the conveyer progresses the blades standv upright and advance the thus gathered matches lalong-the narrow slotted portion of the bottom. See Fig. 11.

The box trays are delivered to the spaces between succeeding blades 35-of the conveyor 34 at a point directly beneath the slotted ortion of the bottom where the blades are 1n upright position, or substantially so, the matches thus being supported above and in close relation to the inserted tray. (See Figs. 2 and 11.) The portion 33 of the slot in rear o f the tray is suiiciently wide to' permit the 'matches-to fall from the bottom of the hopper, and hence as each tray and the superposed matches pass to and 'beyond the slotted portion 33 of the hopper the matches, being unsupported, are progressively deposited in the underlying tray, their uniform descent being contributed to by the i short rapid vibration of the hopper. ..The width of the space between the side eXtensions 24 of the hopper is a trifle less than the length of a tray, and the width of each space between adjacent blades 35 of the conveyer is a little greaterthan that of a tray.

l means, such for example, as spaced rotating 51 and, Perforce, advancing ortending to so on.

the conveyer Aare slightly pinched between the side extensions, and the latter thus eifect vibration of the trays in contact therewith and insure the settling of the matches within thetrays. i

` The trays are fed through a horizontal guide structure 49 on the table to the spaces between the blades 35 of the conveyer, which guide structure includes spaced top and bottom members arranged' to provide a guide wayat right angles to the upper horizontal run of the conveyer. The trays are fed end to end through the guide way from 'a suit-f` able feed trough 50 (Figs. 1. and 2) lead- 15 ing thereto froman'y convenient source of tray supply, and they are movedA thence toward the conveyer by frictional feeding rollers 51 the peripheries of which contact with the respective -sides ,of theopposing trays. These rollers are fast on the lower ends of vertical shafts 52 having their bearings in a' bracket 53 which Vstraddles'the 4guide structure 49, the sides of the latter being open, as at 54, for the passage of the peripheries of therollers ,to the o posing See Fig.`.10.' Thel upper portions of the shafts 52 bear grooved sides of the trays.

pulleys 55 about which passes an endless belt 56 from a` by suitably-disposed idlers 58. turns the pulleys 55`in the directionslndicated by the small arrows thereon in Fig. 2,

thus correspondingly turning the feed rollers advance the proximate trays through the guide structure 49. Afs- 'the space between adjacent blades 35 reaches-la position in line vertically with the` axis of thechain wheel 40, the leading trayis pushed into such space by the frictional action ofthe rotating feed 'rollers on the adjacent trays, the rearward blade 35'immediately moving laterally of the inserted tray and acting as an end st o for the next .succeeding exterior tray untll 'anothertray-receiving space of the conveyer is in alinement with vthe latter tray, and

Itis to be noted that the friction rollers 51 are driven at a high surface speed compared with the speed of the conveyer' 34, so as to project the leading trayffully upon the conveyer while the latter is moving la substantially inappreciable distance; such tray when positioned upon the conveyer impinging against the opposite side extension 24 of the match hopper. It is also. to be noted that 'the inner adjacent ends of the" two rows of blades 35, '36: are slightly separated, as at 59, toaccommodate the lower depending edge of the side extension just mentioned, andv provide sufficient clearance for the traveling conveyer.

j horizontal portion 63 which extends parallel grooved `drive wheel 57' on the' main shaft 48. The belt 56 on itsway from the drivewheel to the pulleys 55jis guided The belt 60 designates a rod extending longitudinally of the hopper so as to overhang and bear yieldingly upon the mass of matches y during their descent and thus prevent their withand near to thehorizontal path of the blade extensions 35. The portionl 63 is provided near its free end with flanged side pieces 63 which overhang and rest upon the upper edges lof the side extensions of the `hopper and thus "permit limited yielding vertical movement of the guard member. This guard member thus provides for vthe lower portion of the hopper a yielding throat .structurewhich efe'ctually gages and limits the levelof the matches flowing to and between the blade extensions above tne trays while such extensions'are entering into and passing through the lower portion of the hopper.

The shucks are 'delivered to thel spaces' formed 'by and between succeeding Vblades 36 of the conveyer; such shucks in the present instance'being fed in end to end procession along'a rearwardly extending chute'64, the delivery end of-which lies adjacent the path of the blades36 and in substantial horizontal alinement` with the axisof the wheel 40. The chute comprises a bottom and-upstanding side walls spaced thereon to guide the shucks, end to end, with one of the long narrow sides of each shuck supported on the bottom. The side walls are terminate in advance of the delivery end of the chute to provide a space equal v`to the length of a shuck or substantially so, so that the shucks upon entering the space may be shifted latterally therein toward the conveyer.; (See Figs.`7, 8 and 9). VThe delivery end :of the chute is provided with an end-plate 65 .which acts as a stop for the leading shuck,

and-constitutes with the proximate parts of the chutev a throat' for the guidance of the 'shucks to the conveyer. Reciprocable within and transversely of the throat is a head 66, thel face of which acting against the opposing shuck, moves it bodily toward the conveyer. This.l head 66 is formed on' the upper end of a lever 67 which is fulcrumed at its lower end on a shaft supported in brackets '68 on the main frame. (See Figs. 1, 4 and 5). On the body of the lever is a laterally-projecting stud 69 bearing-an antifriction roller 70 which is held yieldingly in contact with the flmction'al face of a cam 71 by means of a retracting spring 72 secured at its respective ends to the lever and to a pin 73 on a stationary bracket 74 on the frame. The cam is mounted to turn loosely on the main shaft, said shaft being geared with the cam through anappropriate gear train. In the present instance, the main shaftbears a spur wheel76 which meshes with one, 77, of two spur wheels Sleeved to turn as a unit on a stud-shaft 78 rojecting from .the bracket 74 above reerred to, theother spur wheel, 7 9, of the pair meshing with a spur wheel 80 on the hub of the cam 71. This cam is provided with vtwo high points 81 diametrically opposite to each other, and the ratio of the gears is such that the lever 67 is rapidly reciprocated when each succeeding shuckfreceiving space of the conveyer is positioned to receive a shuck laterally from the delivery throat of the shuck ch'ute. There is suiiicient space in the delivery throat, between the path of entrance of a shuck thereto and the conveyer, to permit the lever head in its acting stroke to advance two shucks, side by side, toward the conveyer, one shuck entering the conveyer and the other remaining' in proximity thereto in position for insertion by the succeeding active stroke of the lever head on the next shuck delivered to the throat. I preferably arrange on the inner wall of the throat, adjacent the conveyer, a block 82 having a serrated friction face 83 slightly wider than the open end of the shuck, so that eachV shuck which is advanced in close relation 'to the path of the conveyer is gripped and held between the block and the outer wall of the throat luntil such shuck is forced into the conveyer.

occupy a horizontal position in endwise re lation to the trays asn-the latter are successively introduced to the conveyer. The shucks and trays thuslpositioned progress beyond the hopper, and thereafter the filled trays are entered into their respective complementary covers on the conveyer.

In the present instance the trays are gradually pushed endwise into the covers by means of an endless seriesof horizontallyrecprocative plungers 84 which are mounted in spaced parallel relation to each other on an endless conveyer 85, the upper run of which is mounted and arranged to travel adjacent 'to, and in the same direction as, and concurrently with the upper run of the tray-ancl-,shuck conveyer. Each plunger, in

`with au underbeveled nose` or shoulder which overhangs the opposing end of Athe tray when theehead impinges against the latter, and also overhangs and presses upon f endless series and supported by two sprocket i wheels 89,90, one, (89), of which is mounted on the shaftl41 and the other (90) of which is 'mounted on a shaft 91 having its bearings in brackets beneath the table. The shaft 91 is equipped with a-pin wheel 92, similarly to the shafts 41, 42, with the pins 93 of which likewiseengages a worm wheel 94 on the main shaft. Thus the plunger conveyer is timely driven in respect to the trayand-shuck conveyer. plunger conveyer are provided on their outer faces with transverse ribs 95 which provide parallel guide spaces for the plungers 84. Alinement of the plunger studs with the ends of the cam-way 87 is insured by their contact' with curved end irons 96 `1, 2 and 15.)

Beneath the horizontal run of the plunger conveyer 85'is a rail 97 which serves as a guide and support for'the lower run of the conveyer in its travel, and also as a guard to prevent the escape of the plungers from the conveyer. This rail is, in eii'ect, a part of the rail 43 above referred to, and is correspondingly supported-by the standards 44. The rails are provided with appropriate channels 98, 99 for the reception respectively of the blade extensions 35 of the conveyer 34, and the heads 84 of the plungers 84, as seen in Fig. 6.

I preferably provide a suitable hold-down device for the shucks in the region of their.

' other end of the arm is pivoted to a suitably-disposed bracket 102 on the table, and the block by its weight exerts sufcient holding pressure on the successive shucks passing thereunder at the instant the trays are being entered into the proximate open ends of the shucks. ('See Figs. 2 and 3.,) The The links of the to afford .guides for the opposing ends yof the filled trays when they are being pushed 'into their complementary shucks. v

It is to be noted that the upper run of the conveyer 34 is guided along the top of the table by bars. 105, 106 which are aiixed tothe table in spaced parallel relation to each other, so as to extend `longitudinally of the table inproximity to the respective edges of the said conveyer. The guide bar 105 along the rearward edge of the table is of suiiicient height to serve as a stop for the opposing ends of the shucks while the trays are being inserted thereinto. (See Fig. 2.).

The other bar 106 is iush with or below the upper surface of the body ofthe conveyer bar 107 on the table, to guide thel upper run of the plunger yconveyer on the table. (See Fig. 3.) i

-I preferably though not necessarily mount` on the continuously-driven shaft 91 of the vsprocket wheel 90 fr the plunger conveyer,

a corresponding sprocket wheel 90 which receives the links of the tray-and-'shuck conveyer and serves as an auxiliary driver therefor.

The shucks with the filled match' trays contained therein are'advanced by the carrier to alposition partially around the wheel 39 and they are thence discharged by gravlty down a chute 108 leading to a suitable receiving table, as 109, as seen in Fig. 1.

It is to be noted that the speed of the trayandshuck conveyer may be timed to permit the feeding of two or more trays and two or more shucks to the conveyer at each. inserting operation of the feeding mechanisms, in which case .the plunger conveyer will be operated concurrently with the tray-and-shuck conveyer. l
