CIGAR-BUNCHING MACHINE..

SPECIFICATION forming part of Letters Patent N o. 377,748, dated February 14, 1888. Application led September 30, 1886. Renewed uly 7, 1887. Serial No. 243,634. (No model.)

' of Detroit, in the county of Wayne and State of Michigan, have invented new and useful.

Improvements in `.Gigar-Bunchi'ng Machines; and I do hereby declare that the following is a. full, clear, and exact description thereof, reference bein gv had to the accompanying drawings, which form a part of this specification.

This inventionrelates to new and useful improvements in cigar-bunching machines of that class in which the bunch is producedby rolling the wrapper and filler within a fold of the bunching-cloth, and wherein additional mechanical devices are provided for dropping or depositing a regulated amount of filler for each bunch ontothe bunching-cloth 5 and my invention ,consists in the construction, arrangement, and combination of different parts, by means of which I obtain an improved Operation of the machine, all as hereinafter described, and set forth specifically in the claims.

In the accompanying drawings, which form a part of this specification, Figure l is a perspectiveview of my machine. Fig. 2 is a side elevation thereof. Fig. 3'is a plan of the bunching-table removed. Fig. 4 is a vertical central longitudinal section on the 'line x w of Fig. 1. Fig. 5 is a cross-section through the compression-chamber. Figs. 6, 7, and 8 are diagram sections illustrating the different pof sitions of parts in the operation of bunching.

A is the bunching-table, upon which the bunches are rolled. The forward end of this table is provided withJ the individual fillerpocketB, formed with -closed or partially-closed ends, sides, andbottom. Farther forward the table is provided with the bunch-receiving opening C, and to the forward end of said table is secured the roller D, to which the forward end ofthe bunching-apron E is attached,

the rear end of said apron being attached to a roller, D', secured above the bunching-table between the roller D and the compressionchamber. The rollers D D' are preferably removably secured, and one may be provided with suitable devices for adjusting the slack of the bunching-cloth."

Fis the carriage which carries the bunchingrollersG H. Itis supported on the bunchingtable by anti-friction rollers a, which engage vwith the V-shaped edges b of the bunchingtable, and is provided with handles c, all so arranged that the operator by taking hold of the handles can reciprocatingly actuatethe Acarriage between its rearmost position (shown PATENT QFEICEH in Figs. 1, 2, 3, 4, 6) and its foremost position,`

(shown in Fig. 8.) In the first of these positions the rollers G H are in rear of the fillerpocketl B, while inthe last positionfthesel rollers are in front of the bunch-receiving' lopening C, suitable stops being provided ,to

arrest the travel of the carriage at these posi-,

tions. f y

The bunching-roller His the bunch-forming roller proper, and it is preferably cut away to correspondwith the desired shape of Vthe bunch, and may be removably secured in its journals in any well-known way, to permit yof exchanging it for rollers of other desired shapes.

filler-mold is shown in cross-section in Fig. 5,

where itis removably secured by the set-screw d, so that it may be ,readily exchanged for a mold of different form.

L is a reciprocating plunger in the compression-chamber K and mold K, and is of a shape corresponding with the contour of the mold used. It is detachably securedy to the plunger-rod L, for thel purpose of exchanging it readily to fit differentshaped filler-molds.

A vertically-reciprocating gate, M, is held in guides g at the front end of the 1illerboxr I,

and this gate carries at its upper end a rack- .bar, h, which engages with the segmentgear i, koperated by the hand-lever jand supported on top of a suitable standard, f, to whichis also secured a guideroller, k, for thev rackbar h. y

The gate M is formedwith a recess, N, in ywhich a vertical plunger, O, moves, and to the back of the gate is secured the knife P. The plunger O fills the recess N of the gate. It has a retract- IOO The bunching-roller Gguides the bunching- Y k `the forked end of a lever, n.

ing-spring secured to the plunger-rod Z, which latter slides in a suitable guide on the gate, and has aprojecting stud, m, engaging between The lever n is fulcrumed to the gate M, and to its rear end is pivotally secured the rod o, which slides' through a guide-hole in the stationary bracket p, and has the stop-pins q q secured to it, to arrest its up-and-down travel when the gate Mis moving, in order to produce a separate movement of the plunger O within the recess N of the gate M.

The plunger L in the mold K of the compression-chamber K is operated by means of a foot-lever, Q, fulcrumed at 1', and provided with a foot-rest, B', pivotally secured to its lower end. A roller, s, is secured in the heel of this foot-rest, and travels on a guide-track, t, in which is an offset, s', which holds the footrest in its forward position against accidental displacement.

To the upper end of the foot-lever Q is fulcrumed at a the lever B, the upper free end of which engages into a slot of the plunger-rod L', while the lower end is connected by means of a link, S, to a rock-arm, T, secured on a rock-shaft, U. VTo another rock-arm, T, on the same rock-shaft is adjustably secured the weight V. A stop, o, on the rear side of the rock-arm T arrests the rock-shaft U from turning farther backward under the action of the weightV, thereby holding the parts connected therewith in the normal position shown in the drawings.

The rock-shaft U is provided with a third.

rock-arm, T, to which the lower end of the detent Y is pivotally secured'. This detent passes through a guide hole in the standard w, and is adaptedv to engage with its free end into a notch, f1, of the segmental circular rock-arm Z, which latter is secured upon a rock-shaft, z. To the same rock-shaft z is secured another rock-arm, a', which carries the feed-door J, and two coil-springs, b c', are placed upon the rock-shaft, so arranged that the tension of the spring b keeps the feed-door open, while the spring c acts as a cheek-spring to prevent the said door from opening too far.

The top of the box I is provided with a lateral extension, d, which forms a small table in front of the filler-receptacle f, secured in rear thereof and communicating therewith through a small opening, g.

The whole machine is supported on a table, preferably on short legs, to raise it ashort distance above the top of the table,to keep it free from the spilled tobacco and permit ofits being cleaned readily. The supporting-table is from the machine, while No. 2 operator, facing the left side of the machine, keeps the table d supplied with filler material from the fillerreceptacle and feeds the same into the compression-chamber K when wanted. .He also places a binder for each bunch on the bunching-apron from a pile of prepared binders,with which he has supplied himself previously.

The operation of bunching is carried on as follows: N o. 2 operator fills the compressionchamber K with filler, then closes the door J. The closing of this door actuates the rock-shaft, to which it is attached,and carries the notch y into engagement with the detent Y, which latter is raised up suiiicientlyby the weight V to engage into said notch. The feed-door being thus locked, the ller inclosed in the conipression-chamber is now compressed by operator No. 1 actuating the foot-lever Q by placing his foot on the foot-rest R', tipping it up to pass it over the o'set s', and pushing it ahead. By means of the connections described the free end of the lever R pushes the plunger into the compression-chamber until the compression obtained overcomes the resistance of the weight V, when the lever B will cease to further compress the filler and merely turn on its fulcrum u and lift up the weight V. By proper adjustment of the weight V on the rock-arm T any desired compression of the filler may thus be obtained. The filler is now con tained in a compressed body in the forward end of the compression-chamber K, projecting into the recess N in the gate M and abutting against the face-plate ofthe gate M. Operator No. 1 now seizes the hand-lever J, and, pushing it backward, causes the gate M to descend. This movement first causes the knife l? to cut off all that portion of the compressed filler contained in the recess N, and then causes the plunger O to expel that cut-off portion.

from the recess N and deposit it on the bunching-cloth, which by this time has been pressed by the descending gate into the bunch-pocket B, as shown in dotted lines in Fig. 6. lThe plunger O is moved up and down by the gate M, and is given an additional movement by t-hexupper pin, q', on the rod o, which, when arrested during the downward movement of the gate M by the guide-bracket p, causes the forked lever n to oscillate and push the plunger downwardly, while in the reverse movement of the gate M the lower pin, q, strikes the under side ot' the guide-bracket p and restores the plunger O again into normal position. The filler having been deposited on the bunehing-apron, the operator reverses the movement of the hand-lever j, which operation is assisted by the counterweightj. Operator No. 2 places a suitable binder, X, on the bunching-apron as soon as he has attended to the feeding and closed the feed-door. The position ofthe bunching-apron before the filler is deposited is shown in Fig. 4, wherein the bunching-apronis shown tobe folded under the two rollers G H. This fold is partially drawn out in forming the bight A'for the filler, as shown in Fig.7,; and asf-op- .erator No. l now proceeds to roll the bunch by drawing the carriage F toward him, this fold is entirely used up, but not before the filler is entirely inclosed in the bunching-apron,

' and the roller having passed over it, or nearly so, as shown in Fig. 8, when in the further i movement of the carriage the bunch will be rolled in the bight of the bunching-apron. Duringthis rolling ofthe bunch the binder is drawn around it, andthe bunch is kept in contact with the launching-roll H. The forward movement of the carriage is arrested by a suitable stop, S4, in the position shown in Fig. l,

. wherein the perfected bunch is shown to have dropped into the opening C, being still held in the bight of the bunching-apron. After having drawn the carriage forward the operator vimmediately reverses it,^which movement takes the bight out of thge bunching-apron and carries the rollers G H back into the starting position and frees the bunch, which is removed by the operator and placed into a mold. (N ot shown.) vWhile operator No. 1 is rolling the bunch, operator No. 2 proceeds to again supply new ller into the compression-chamber. Although the chambercontains enough for several more bunches, it is preferable to feed after each compression, so as'to avoid any great variation in the travel of the foot-lever. The door J opens automatically as soon as the compression of thefiller in the chamber K/ has attained the desired degree, on account of the withdrawal of the detentY from the notch y as soon as the weight V rises. As soon as the operator, however, releases his pressure against the foot-lever Q, the weight V is free to drop 'and re-'engage the detent as soon as operator No. 2 closes the feed-door after feeding the filler. The foot-lever Q will ease off automatically on account of the counterweight Q'.

The use of two bunching-rollers, G H, constitutes an important improvement in the operation of the machine, as I am'. thereby enabled to use a much larger bight in the bunching-apron than with one roller. The advantage I gain thereby is that the filler becomes completely inclosed in the bi ght in the bunching-.apron before there is any tendency to roll the bunch, as shown in Fig. 7.

A further advantage in the operation of the machine is afforded by the location of the bunch -receiving opening C, which does not alone require a shorter travel of the carriage than in the old way of placing the same at the front end of the table, but affords the advantage of bringing the slack in the bunchingapron in rear of the carriage. The filler is thus delivered into the pocket B against the bunching-apron, which only yields gradually to form a pocket as the gate depresses it, and the filler, in passing from the recess N in the gate onto the bunching-apron,is not disturbed at all. rIhe use of two bunching-rollers, .G H, also presents the advantage that thebunchingroll H may be made of any desired shape to form the bunch without.k interfering withgthe proper movement of-the bunchingapron,

which is guided by the front roll.

The automatic openingl of the feed-door .I indicates to the operator that the required compression of the filler in the compression- :chamber is obtained, and ne therefore stops pushing the foot-lever Q'any farther; but, if desired,an automatic stop may be added; and to thisend I provide the rock-arm T', which swings the weight V,withaforward extension, t', and to this I attach a connecting-rod, t, which holds one end of the plate t, the other end of which is pivotally secured tothe lower end ofthe foot-lever. This plate carries one or more dogs, w, so arranged in connection with a rack-bar, w', secured underneath, that when the plate t' is lowered, by means of its connection with the rock-arm'ofthe lever V, the dog or dogsengage into the rack-bar, andV thereby automatically stop the further moves ment of the lever after it has accomplished its Work.
