MACHINE FOR APPLYING PAPER, MOLDS TO CIGAR-BUNCIIES.

Application filed August 10, 1918.

To all whom it may concern:

Be it known that I, LOUIS R. GINDRAT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Machines for Applying Paper Molds to Cigar-Bunches, of which the following is a specification.

This invention relates to improvements in machines for making and molding cigar bunches, and particularly to mechanism whereby the completed bunches are wrapped in paper molds before the bunches are delivered from the machine. While one bunch is in process of formation, the preceding bunch is being wrapped in a paper mold, so that the operation of the bunch forming mechanism is not delayed by the addition to the machine of the paper wrapping mechanism. Usually, cigar bunches are placed in wooden molds where they are kept until the cigar-maker removes them to apply the wrapper, and considerable time is lost in placing the bunches in the molds and removing them therefrom. Furthermore, when the bunches are made by automatic machinery in large quantities, a great number of wooden molds is required to hold the bunches. By applying paper molds automatirally to the bunches, the use of wooden molds is dispensed with and a saving in labor results, as the bunches require handling only once, that is, when the paper mold is removed to apply the wrapper.

The mechanism for applying the paper molds to the finished bunches is shown in the accompanying drawings in connection with a cigar bunch-making machine of the type illustrated in the patent to Richard Bright, No. 1,260,137, dated March 19, 1918, and is substantially the same as the machine shown and described in my patent il-1,281,344, Oct. 15, 1918. In the machines of said prior applications, the apron which rolls the binder on to the filler and completes the bunch, ejects the latter on to a conveyor which carries the bunches from the machine. In the present application, the apron delivers the completed bunches to the paper wrapping mechanism which forms the subject of the present invention, and after the paper mold has been applied, the bunch is delivered from the machine.

Specification of Letters Patent.

Patented June 8, 192d.

Serial No. 249,302.

Fig. 7 is a central, vertical, longitudinal section through the upper half of the machine, parts being omitted;

Fig. 8 is a similar view through the forward part of the machine;

Figs. 9 to 14:, inclusive, are fragmentary views illustrating the operation of the paper wrapping and twisting mechanism;

Figs. 15 and 16 are, respectively, side and plan views of the knife or shears for outtingotf the paper mold strips;

Fig. 17 is a view, partly in section and partly in elevation, of the spindle carrying the paper twisting pins and one of the rollers for the paper wrapping belt; and,

Fig. 18 is a similar view of the lower roller and idler within the pocket of the paper wrapping belt and the spindle for said roller.

Referring to the drawing, A indicates the supporting frame of the machine, which is composed of two similar side frames, 1 and 2, suitably connected together by cross-rods. In the lower part of the machine (Fig. 1) is mounted a motor 3, which operates a worm 3 on a shaft 3 and said worm engages a worm gear 4, secured to a shaft 5, journaled in suitable hearings in the frame, whereby said shaft is constantly driven. Upon this shaft is ournaled a gear 6, which meshes with a gear 7, upon a main shaft 8, journaled in the upper part of the frame. Upon the main shaft 8 are mounted the various cams for operating the feeding and bunch forming mechanisms. By momentarily rocking a pedal 9, Fig. l, clutch mechanism, not shown, will cause the gear 6 to be connected to the driving shaft 5 and this gear will be automatically disconnected at the completion of one revolutien,'unless the operator wishes to continue the machine in operation, in which case the pedal is not released by the operator until it is desired .pack the filler therein.

to stop the machine. The clutch mechanism referred to is fully described in the aforesaid patent of Richard A. Bright, but any suitable clutch mechanismv may be employed. In the ordinary operation of the machine, the operator allows the machine to come to rest after each revolution of the gear. The gears 6 and 7 are of the same diameter and therefore, in operation, the shaft 8 makes one revolution each time the clutch is released, and then stops.

The mechanism for forming the bunches is the same .as shown in my aforesaid application. The filler f is held between bolts 0 and (Z, wound on a reel 0, and these belts are drawn from the reel on to spools ,7 and h, delivering the filler on to an endless travel ing belt 10, (Fig. 7) which feeds the filler to a pocket or receiver 1", wherein it is packed by sets of fingers 11 and 12, operator by cams on the shaft 8 which fingers move alternately into and out of the receiver to At each operation of the shaft 8, a knife 13 moves transversely through the receiver, cutting off a bundle of filler; a gate 14, which forms part of the wall of the receiver, then moves downward and an ejector 15 then moves forward and carries the bundle of severed filler down on to an apron 16, and this apron is then operated to roll the binder upon the filler and form the bunch.

The improvements which constitute the subject of the present invention all relate to mechanism added to the bunclrforming machine, but timed therewith and adapted to apply a paper mold to the completed bunch when it passes from the rolling apron 16. .Vhile the traverse arms I; and t which operate the apron roller 16 are moving for ward, in the operation of rolling a bunch, a sheet of paper of the proper length and width to form a mold is delivered into position to receive the bunch from the apron, and while the traverse arms are receding, the paper wrapping and twisting mechanism rolls the sheet of paper on to the bunch and twists the ends of the paper, and the bunch, inclosed in the paper wrapper or mold, is then delivered from the machine.

The paper feeding, cutting and wrapping mechanisms are all operated intermittently from a segmental gear 17, upon the shaft 5'. This gear, as shown in 1 and 3, at each half revolution of the shaft 5, engages another segmental gear 18, upon a shaft 19. These two gears are formed so as to constitute a stop movement, and the gears are proportioned so that during one-half revolution of the gear 17, the gear 18 will be revolved twice, and during the succeeding half revolution of the gear 17, the gear 18 will remain stationary. The gear 18 drives the shaft 19 and upon said shaft is mounted a beveled gear 20, whlch meshes with a beveled gear 21, upon an inclined drive shaft 22, which latter, as shown in Figs. 1 to 4, inclusive, carries at its upper end a beveled gear 23, meshing with a beveled gear 24, upon a shaft 25, extending transversely of the machine. The shaft 25 carries a segmental gear 26, which meshes with a gear 27, these two gears constituting a stop movement and the ratio of gearing being such that during one-half revolution of the gear 26, the gear 27 will make two revolutions, and during the succeeding half revolution of the gear 26, the gear 27 will remain stationary. The gear 27 is mounted upon a shaft 28,'which. carries a spiral gear 29, meshing with a similar gear 30 on a shaft 31. This shaft 31 carries a spur gear 32, which meshes with a spur gear 33, of the same diameter, upon a shaft The shaft 31 carries a feed roller 35, and the shaft 34 carries a pressure roller 36, which rollers, when the shafts are operated, feed paper from a roll of paper 37. The paper is fed from the paper roll transversely of the machine into position to receive a bunch from the apron 16. At each: revolution of the shaft 5, and while the traverse roller of the bunch-forming mechanism is rolling the binder on to the bunch, a sufficient length of paper to form a mold is fed from the paper roll and as soon as the paper feeding operation ceases, this length of paper is cut off by a rocking knife blade Z0, leaving a sheet of paper, indicated at p in Figs, 2, 7 and 3, in position to receive the bunch from the apron.

The knife blade Z1 is mounted upon a rock shaft 38 and operates against the shearing edge of a stationary blade 39. This knife blade is rocked, at the moment when the feeding operation ceases, by a cam 40, Figs. 3 and 4 on the shaft 25. This cam operates the knife blade through the medium of a push rod 41, which is constantly pressed toward the cam by a spring 42 and is connected to a lever 43 on the rock shaft 38,

'whicl'rcarries the knife blade.

Immediately after the paper strip has been severed, the bunch passes from the apron on to the paper sheet, the position of the bunch I). and of the paper strip, at this moment, being indicated in Figs. 7 and 8. The traverse roller and apron then recede, to the dotted line position, Fig. '7, to receive another bundle of filler, and at the commencement of this retreating movement, the paper wrapping and twisting mechanism commences to roll the paper about the bunch. This mechanism as shown in Fig. 4, and Figs. 7 to 14, inclusive, comprises an endless belt 44, which is driven by a roller 45, the roller in turn being driven by a gear 46, on the roller shaft 46*, which meshes with a larger gear 47 on the shaft 25.

The endless belt 44 extends upwardly over a roller 48, which is mounted in fixed bearings, thence downwardly around another roller 49, which is also mounted in fixed bearings, thence upwardly over a roller 50, which is movable, thence downwardly around another movable roller 51, and thence over an idle roller 52 to the driving roller 45. In the normal positions of the movable rollers, the belt, passing around the rollers 48, 4:9, and 50, forms a pocket 4;, almost directly beneath the point where the bunch is delivered from the apron, and the bunch passes from the apron into this pocket. The roller 50 is carried by a spindle 50", in arms and 53, Figs. at and 8, which arms are secured to a shaft 54, journaled in bearings 55, upon forked ends of a lever 56, which is secured to a rock shaft 57. Springs 58, surrounding hubs on the arms 53, and engaging the bearings 55, normally tend to move the roller 50 from the position shown in Figs. 8 and '9, toward the roller 48, as shown in Fig. 10, but this movement is prevented by a spring stop or latch 8, (Figs. i and 6) which is engaged by the spindle of the roller 50 at the end of each paper wrapping operation. An arm 59, secured to the rock shaft 57, engages a cam 60 on the main cam shaft 5, of the cigar bunching machine and a spring 61, secured to the lever 56, in advance of the rock shaft 57, holds the arm 59 in engagement with the cam 60.

The latch 8 comprises a bolt sliding in the side frame and having a disk 63 at one end and a conical head 63 at the other end. A spring 63 normally presses the latch inward into position to be engaged by the spindle 5O of the roller 50, as indicated in Figs. 8 and 9.

When the traverse roller and apron move down to deliver a bunch into the pocket 0), a forked projection 62, secured to the bearing 25 on the traverse arm t, engages the conical head 68, of the spring latch s, as shown in Fig. i, and moves the same outwardly, withdrawing the disk 63 from the path of the spindle of the roller 50; but simultaneously therewith, a projection 64, carried by the arm'of the traverse roller comes in line with said spindle and, taking the place of the disk 63, prevents the springs 58 from moving the roller 50 to close the pocket while the traverse roller is in its extreme forward position and the bnnch'is being delivered on to the paper strip, (see Figs. 7, 8, and 9). WVhen the traverse roller recedes, this projection 64L is removed from the path of the spindle, and the springs 58 then swing the roller inward, closing the pocket over the bunch, as illustrated in Fig. 10.

The wrapping belt 4% is started into operation by the train of gearing heretofore described simultaneously with the closure of the pocket. When in the pocket, the bunch is engaged on opposite sides by the belt and also by a small roller 65, which rests upon and is driven by the roller L9, but turns in the opposite direction, and the paper strip is quickly rolled about the bunch. After the bunch has been given eight to ten revolutions in the pocket, which suflice toroll the paper around the bunch, the ends of the paper, which project beyond the bunch, are engaged for an instant, while the hunch is rotating, by a pair of twisters in the form of pins or rods 66, which are swung from below upwardly toward the center line of the bunch and engage the extended ends of the paper. As the bunch revolves with these twisters bearing against the paper near its ends, and pressing said ends toward the axis of the bunch, the ends of the paper are twisted, thus closing the paper over the bunch and giving form to the ends of the bunch. These twisters are fastened to sleeves 67, (Figs. 8 and '17) secured to the spindle 68, which carries the roller as, and are rocked into position to twist the ends of the paper, at the proper time, by a cam 69 on the shaft 25, which actuates a push rod 70, connected to a rocker arm 71, on one of said sleeves, (Figs. 8 and 9 to 1 inclusive). The cam 69 normally holds the push-rod in an upper position. and thetwisters are thereby held in their lower position. When the depression in the cam passes the lower end of the push rod, the latter drops by gravity, thereby throwing the twisters upward, as shown in Fig. 11, and immediately thereafter the push rod and twisters are restored to normal positions by'the cam which rotates in the direction indicated by the arrow.

Figs. 8 to 14:, inclusive illustrate the operation of rolling the wrapper on to the bunch and of twisting the ends of the wrapper. In Fig. 8, the apron roller 16 is inits ex treme forward position, and the bunch I) is being delivered from the apron 16 on to the paper strip 2), and the latch s is withdrawn from its normal position by the forked arm 62, (Figs. 4 to 6) the roller 50 being held away from the roller 48, in Fig. 8, by the arm 64, carried by the traverse arm. In Fig. 9, the apron roller 16 is about to recede and the bunch 5 has dropped into the pocket on to the small roller 65. The projection 64 on the traverse arm is moving out of engagement with the spindle on the roller 50, but the latch s is still held away from its normal position by the fork 62 on the traverse arm. Immediately after the disengagement of the stop projection from the spindle of the roller 50, the springs 58 throw-the roller 50 inwardly to the. position shown in Fig. 10, the roller spindle being permitted to pass the latch because the fork 62 on the traverse arm holds the latch from normal position until the roller 50 can move inwardly to close the pocket. 1m mediately thereafter the fork 62 becomes disengaged from the latch. and the latter returns to normal position. Simultaneously with the delivery of the bunch into the pocket, as shown in Fig. 9, the wrapping belt 44 is started into operation, in the direction indicated by the arrows, by the train of gearing heretofore described, which actuates the driving roller 45. This causes the belt 44 to roll the bunch in the proper direction to wrap the paper strip on to the bunch and the immediate closure of the pocket causes thebunch to be pressed in a more uniform cylindrical shape as the paper is wrapped about it. lvhen the paper has been wrapped about the bunch, the twisters move upward momentarily, as shown in Fig. 11, causing the extended ends 22 of the paper strip to be twisted, which action gives a taper to the bunch at each end and permanently incloses theends of the bunch. When the paper mold has thus been applied, the wrapped buncln'indicate'd at b in Figs. 12, 13, and 14, is then automatically ejected from the pocket. In order to eject the bunch, the forked lever 56 (Fig. 8) is rocked by the cam 60 and thereby the rollers 50 and 51, carried by said lever, are swung downwardly into the successive positions illustrated in Figs. 12 and 13, thereby opening the pocket in the belt and permitting the bunch to drop out, as indicated in the last mentioned figure. The bunch with the mold wrapper thereon falls into a delivery chute m, the bunch showing one of the twisted ends of the wrap per being illustrated in Fig. 14.

After the bunch has been ejected, the lever 56, carrying the rollers 50 and 51, returns these rollers to their normal positions. lVhen the rollers return to normal positions, the roller 50 must be held away from the roller 48 in order to leave the pocket in the belt open for the reception of the next bunch. To accomplish this, a swinging guide 72 is provided, this guide, as shown, being in the form of a bell crank having a downwardly projecting arm provided with a guiding flange 7 2 A spring 73 holds the depending arm of the guide against the bracket 74, which forms a stop, and in its downward movement the spindle of the roller 50 engages the guide flange 72, as shown in Fig. 12, and rocks the guide 7 2 out of its path. As soon as roller 50 passes below the guide flange 72, the guide swings to normal position, as shown in Fig. 13, and as the: roller 50 moves upward, it engages the right hand side of the guide flange as shown in Fig. 14 and rides upward thereon into a position back of the disk 63, on the stop 8, as

shown in Fig. 9, thus leaving the pocket.

open. As before described, when the apron roller moves downward to deliver another the stop 64 on the traverse arm. hen the bunch is delivered into the pocket, and the traverse arms recedes, this stop 64, as before explained, is moved out of the path of the spindle of the roller 50 and the latter then moves toward the roller 48 to close the pocket.
