Referring more particularly to the drawings, 1 is the base of the machine beneath which is an electric motor 2 driving a gear 3, to theshaft of which is also attached a hand-wheel 4:. Meshing with the gear 3 is a larger gear 5, which, by the yoke 6, can

bethrown to-the right orleft so that the clutch recess 7 will engage or disengage the' pin 8 in the shaft of the pinion 9. The

clutch recess 7 has one squared surface and one slanting surface with th'efresult that Whenthe hand-wheel 4 turnedfin the wrong direction the'pin 8 is automatically disengaged by the clutch surface connected to the gear 5, thus preventing the accidental operation of the machine in the wrong direction. The gear-wheel 9 drives a gearwheel 10, which is mounted uponthe main shaft 11 of the machine. From this shaftv the various parts of the machine are driven feed and pressure-rollers 17 18 driven bygears17 and 18; The gear 18, together with its roller, is driven by the shaft 19 through the pulley 20 and belt 21, which passes over the pulley 22 on the main shaft 11. Y

Supported at a lower point, in the machine shown at a point below the base, is a roll 23 of substance such as cork, gold paper or other like tissue, which it may be desired to apply to one edge of the paper passing,

from the roll 13 so as to be located at one end of a cigarette-paper, tube or cigarette which may be made by the machine. The length of the roll 13 is made equal to the length of the paper or tube to be produced, the length of the tube being the full width of the paper .upon the roll 13. The length of the roll 23, i. e.,-the width of the strip thereof, is made equal to the length of the tip desired. The strip from the roll 23 passes over guide-roll 24 and through guides 2526 to a roll 27 being thus guided so that one edge of the strip from the roll 23 coincides with one edge of the strip from the roll 13, as shown, in Fig. 17 As the strip from the roll 23 passes from the guide 25, it is brought in contact with a glue-roll 28, which is supplied with glue from the glue pot 29, the roll 28 being driven by a sprocket chain 30 from a sprocket upon the shaft of the gear 18. After passing the roll 27, the tipping strip, being then coated with glue, comes in contact with the paper from the roll 13 and passing through-the pressure rolls 17 18 driven by the gears 17 and 18 is pressed so as to be firmly secured thereto, forming a composite strip 31. This composite strip passes over a roller 32 to the feeding, severing and forming part of the machine.

In the embodiment shown, the feeding is intermittent and since the rolls driven by the gears 17 and 18 move continuously, the

slack in the composite strip 31 varies. In-

order to keep this strip at a uniform tension in splte of the variation in feed,I provide a floating roll or spool 33 which is supported by the strip and moves up and down as the slack varies, thus securing the desired uniformity of tension.

The composite strip 31 is fed to a severing apparatus having two members 34-35, the

upper of which 1s pivoted at 36 and pressed toward the lower member by a flat- .spring 37 so as to be held in close cutting e gagement therewith. The outer end 34 of the member 34 is connected to a link 38 which has at its lower end a pin 39 engaged by a cam 40 on the main shaft 11. As the main shaft is rotated, the member 34 is actuated by the cam 40, the cam being so timed that the cutting edge of the member 34 shall descend at the proper instant, its downward spring movement being limited by ,the

stop 34.

strip -31 to the severing device 34-35, I provide a reciprocating slide 41 which carries uprights 42 in which is pivotally mounted a jaw 43 adapted, in conjunction with the slide 41, to clamp and release the strip 31 so as to carry the strip 31 forward whenever the slide 41 moves forward. The clamp is actuated by a rod 44 connected to a bellcrank lever 45, which at its other end has ,a roller 46 engaged by a proper cam 47 which lifts the clamp 43 at proper times so as to release the strip 31. A spring 48 connected to the bell-crank at other times holds the jaw 43 in clamping engagement with the strip. The cam 47 is mounted on the shaft 49, which is driven by a gear 50 meshing with a gear 51 loosely mounted on the drum shaft 52 and in turn meshing with a gear 53 secured to the main shaft 11 (Figs. 1 and 3). The slide 41 is caused to reciprocate by a lever 54 pivoted at 55 and connected to the slot 59 so that the position of one end of the rod 57 can be shifted for the purpose of adjustment so as to vary the throw of the slide 41 and thus vary the length fed to the severmg device. A spring 60 is connected to the upper'end of the lever 58 so as to hold it normally in retracted position and tend to retract the slide 41. The lever 58 carries an anti-friction roller 61 which bears against a cam 62 mounted upon the shaft 49 and therefore driven from the main shaft 11 synchronously with the cam 47. The cam 62, however, is difierently shaped, the shape being such as to give the slide 41 the deslredtmovement at the desired time.

In order to properly guide the strip 31 between the severing members 34 and 35, a reclprocating guide 63 having inturned proections 64, on which the strip 31 rests, is provided. This guide is pivotally mounted at 65 on an arm depending from a slide 66 mountedin a stationary portion of the n1achine-frame and having connected thereto one end of the spring 67, the other end of which is connected to said stationary portion 68 so that the spring 67 tends to retract the slide 66, together with the arm 63 pivoted thereto. To the depdil arm of e For the purpose of feeding the, composite engagement has been made, a forward movement of the slide 41 carries the pawl 69' with it and consequently causes the guide 63 also to -move forward with clamp 43. All these parts continue to move together until the forward end of the detent 69 engages the pin 73 as shown in Fig. 15. This engagement causes the detent 69 to rise until it escapes the projection 72, whereupon the guide 63 is retracted by the spring 67 to the position shown in Fig. 12. The; clamp 43,- however, continues to move forward, still carrying the paper until ,it'has reached the position in which it is shown in Figs. 10 and 12 After it has reachedthis position, the

cam 47 acting through the bell-crank 45 and rod lifts the jaw 43 whereupon the cam 62, acting through the levers 58 and 54 retract the jaw 43 and the slide 41 to the position shown in Fig. The jaw 43 is still held open duringthe whole of the backward movement. -The opening of the jaw 43 causes a projection 74, which in Figs. 10 and 12, is shown engaging the guide 63 so as to lift it slightly, to disengage said guide as shown in Fig. 13, thereby permitting the guid er63 to fall so that its heel engages the paper 31 so as to clamp it against the upper surface of the frame at 7 5, thereby holding its forward end during the interval in which it is released by the, jaw 43. When the jaw 43 again engages the paper, the projection 7 74 again engages the guide 63 causing the guide to rise so as to no longer clamp the I paper against the frame at 75.

Before the guide 63 in its forward movement reaches the severing members 34 and 35, these members have separated so that the guide 63 passes beneath them, as shown in Fig. 15. The end of the paper is thus properly introduced between the severing mem bers and when so introduced can continuously be fed without difliculty by the action ofthe jaw '43. In the absence of means for holding the paper in a definite position and introducing it between the cutting members, therewould be difliculty in causing the machine to handle paper of the thinness necessary for the purpose desired, particularly when pivoted severing members are employed. Before the seve ring members 34 and 35 come together the pin-7 3 causes the detent 69 to become disengaged with the result that the guide 63 is quickly drawn back out of the way ofthe severing members. By this means the paper can be accurately fed and brought between the severing members even though the opening is ing certainty of action and uniformity in the lengths of the strips severed. Figs. 10, 12, 13, 14 and 15 show five positions of the feeding clamp, guide and severing members. Fig. 10 shows the partsin their relation immediately after the retracting of the guide 63 and the full forward movement of the jaw 43, the paper being between the severing members 34- 35.

Fig 12 shows these parts in the same relaparts after the jaw 43 has been fully retracted so that the pawl 69 again engages the projections 72 and the jaw 43 has been caused to reengage the paper at a. new point and raise the guide 63 so that the paper is no longer engaged at the point 75. Fig'. 15

shows these parts .-after they have been moved forward so that the guide 63 extends beneath the cutting member 34 and the pawl 69 has enga ed the 'pin 73 and is about to-be thereby disengaged from the pro ection 72 The next position that the parts will assume is that shown in Fig. 10. By the means thus described, the paper and tipping material from the rolls 13 and 23 arelsecured together and cut into uniform lengths bythe severing members 34 and 35.

In order to produce cigarette tubes, I provide a former and a mandrel cooperatlng therewith, said former'having a recess over which the paper projects just prior to the time at which it is severed from the strip as shown in Fig. 10. In my present embodiment 76 is the former, the same being a cylinder mounted upon and driven by the drum shaft 52. This former has four recesses 77 equally spaced about its periphery. The

shaft 52 by which it is rotated, has an intermittent motion, being driven by the intermittent gear 78, which is driven by the mutilated gear 79, the gear 79 having one-half of its circumference provided with gearteeth meshing with corresponding gear teeth on the gear 78, the other half of its circumference being cam-faced. The result is that during one-half of the revolution of the main shaft 11, while other parts of the mech- 'anism driven thereby are rotating, the shaft 52, together with the drum 76 and other parts actuated solely thereby, remain stationary for the purpose hereinafter set forth.

Coacting with the former 76 are tubular 'mandrels 80, which are, by a movement transverse to their axes, brought into and out of line with the axes of the recesses 77. This is accomplished by a stationary cam 81 small, thus preventing buckling and insur-,

slides 83 moving in recesses 84'of' a revolv- L ing frame 85 keyed to the drum-shaft 52 (see Figs. 2 and 7). These slides 83 carry 5 cylindrical rods or plungers 86. over which slide the hollow mandrels 80 (Fig. 7). The cam 81 is so timed that when any recess 77 approaches the severing members 34 35, the hollow mandrel 80 is elevated as shown in Fig. 10 so as to pass over the end of the strip 31. As the recess moves a trifle closer, the cam 81 releases the slide 83 so that it is drawn downward by its spring 87 carrying its mandrel into the corresponding re,-

as shown in Fig. 12. .The severing member 34 then descends and severs the paper, which assumes theposition shown in Fig. 13. Each slide 83 carries a projection .88, which partially surrounds. the rod 86 and has depending from'it at its opposite end a rack 89.

' This projection also acts as an external guide for the mandrel. Each rack 89 engages a pinion 9O journaled in the former 76 and carrying at its inner end fingers 91 (see Figs. 7, 8 and 9). The extremities of. these fingers are causedv to enter and-withdraw from slots 92 in the drum 76 (see Figs. 1 and 9), these slots being formed by bridges 93 in one side of the recesses 77, (see Fig. .7). The purpose of these fingers is to clasp the paper and fold it over as the mandrels descend into their respective recesses 77. Since the mandrels and their respective racks 89 move synchronously, the fingers 91 being driven by the racks 89 will reach the proper position so as to fold the paper over whenever any mandrel is seated in its slot 77. The position of the fingers 91 before the. mandrel drops is shown at the upper side of Fig. 9. The position after the mandrel drops is shown at the right of Fig. 9, the mandrel being in the bottom of the slot and the fingers being in engagement therewith. The mandrel and the fingers remain in this position until the slot reaches substantially its lowermost position at or about which time the cam 81 begins to force the lowermost slide, together with its mandrel, downward, resulting in the withdrawing of the corresponding fingers 91,- which releases the tube so that it can drop out or be removed, when its mandrel 8-0 is fully withdrawn from the recess by a longitudinal movement hereinafter described. Just after a slot 77 has reached its lowermost positionand after the mandrel has been withdrawn, an ejector 94 actuatedr by a cam groove 95- in which roller pin 96, carried by the ejectors travel, forcibly ejects the tube from the recess.

The mandrels 80 have roller studs 97 connected thereto, which project through slots 97. in the projections 88, being guided and positioned thereby. These roller studs 97,

when the mandrels reach their lowermost cess 77, thusfolding and holding the paper position, are engaged by retracting members 98 carried by parallel lever arms 99-100, the former being rigidly connected to a bevel gear 101 and the latter being pivoted to the frame'at 102, so as to cause the member 98 to be maintained transverse to the axis of the mandrel which it-is withdrawing. The bevel gear 101 is driven by a bevel gear 103 which is mounted on a shaft 104, on which is mounted the arm 105 pivoted at its upper end to an inserting member" 106. This inserting member is connected to the parallel arm 107 so that it is maintained parallel to the axis of the mandrel which is inserted thereby. This insertion member 106 engages apin 97 on one of the mandrels when I the mandrel has reached the position shown at the left hand side of Fig. 9 (see Fig. 5), The shaft 104 on which the bevel gear 103 is mounted has an arm 108, to which is con- Tn'ected a. link 109, which is driven by a lever 110 pivoted at 11 1. The lower end of the lever 111 has connected to it a link 112 which is connected to a lever 113 pivoted at 113 and normally retracted by a spring 113*. This lever-113 carries an" anti-friction roller 114 which engages a cam 115. This cam 115, is mounted on a shaft116 which carries a bevel gear 117 engaging a bevel gear 118 mounted on the main shaft. The ejecting and insertingmembers 98 and106 are thus driven from the'main shaft 11,

simultaneously withdrawing one mandrel when it has reached its lowermost position (see Fig. 5) and inserting the next preceding mandrel so that a mandrel is withdrawn in order to permit a tube to be removed from the recess and a mandrel is inserted so as to be in place when it reaches its uppermost position as shown in Figs. 7 and 10. After the uppermost 'mandrelhas, dropped into its slot 77 and a section of the strip 31 has been severed, as shown in Fig. 13, glue is ap plied to one of the edges thereof by a blade i or conveyer 119 carried by an arm 120 pivot; ed in a support 121. This arin 120 has an extension 122 which is engaged by a pin 123 carried on a disk 124 mounted on the main shaft 11, the pin being soplaced that the blade 119 will be moved toward theedge when the parts are in the position shown in Fig. 13 so as to make contact with one edge of the strip section as shown in Fig. 14. The blade 119 at'the same time assists in folding over the other edge of the strip sec-v tion. The edge of=the blade which carries the glue is slightly upturned and when it is retracted by the spring'125 is in the position to be engaged by a glue roller 126 which engages an intermediate roller 127, which intermediate roller engages a glue roller 128 dipping into a glue pot 129. The rollers 126, 127,128 are journaled ina yoke 130,

, which is free to move on the axis 131 of the roller 128, this axis being journaled in the glue pot. The yoke 130, together with its rollers 126 and 127*tends to fall down by gravity and when in its lowermost positionthe roller 126 makes contact with the edge I of the blade 119. Connected to the rotating drum is a cam surface 132which determines the position of the roller 126, permitting it to descend at the proper time so as to touch the edge of the blade 119- and cover it with glue. This cam surface engages a friction surface on theshaft of the roller 126, causing it to rotate and thus causing the rollers 127 and 128 to also rotate so that they are I all kept properly coated with glue.

After the glue has been applied, the

former 76 moves anda stationary wiper 133 secured to the frame at "134, (Figs. 2 and 10) wipes the glued edgeover on to the unglued. edge of'the section. A' brush 3135, mounted on the frame, gives the glued edge an additional andmore perfect Wipe as the tube is carried by,. hus insuring the production of a perfect joint.

The course of the shown diagrammatically in Fig. 17 showing the path which they take.

Fig. 18 shows a complete tube, the edges of .the strip being connected together in the same I longitudinal line.

The operation of the machine is as follows: After the paper 13 and the tipping strip 23 have been placed in position and passed over and between the proper rollers until they reach the clamping jaw 43 and guide 63, the machine being manipulated during this process by the hand-wheel4, the

electric motor is started. The clamping jaw 43, together with the slide 41, carries the paper forward beneath the severing memwhile clamping the, forward bers 34-35 as shown in Fig. 15. The guide 63 is then released and withdrawn by the spring 67, the jaw 43 continuin its forward mot-ion until the strip has'reacfied the position shown in Fig. 10. As the tipping strip passes the roller 28, it becomes coated with glue. It is then brought in contact with the paper strip and passes between the rollers 17-18 -where the pressure causes the two to adhere. "It is then-fed by the jaw 43 and guide 63 to the severing device, which cuts it off in sections of equal length.- When the paper and tipping strip,- and the composite strip formed thereby,,1s

This .operation is repeated as each mandrel and its corresponding recess travels around the circumference, resulting in the making -of four complete tubes for each parts being properly timed. by the means before 'derevolution of the former 76, the
