BUNCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 681,679, dated September 3, 1901.

,Application led October 5, 1900. Serial No. 32,198. (No model) provements in Bunching-Machines, of which the following is a specification.

This invention relates to improvements in that class of 'machines designed for rolling binders around the llers of cigars; and the objects of these improvements are, first, to control the amount of fLller fed to each binder; second, to automaticallyT roll the filler in the binder, and, third, to automatically deliver the bunch from the machine.

The invention consists in the construction and combination of the various parts, as hereinafter fully described and then pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a cigar-bunching machine, the parts occupying their normal positions; Fig. 2, a similar View, but showing the parts in the positions occupied thereby as the rolling of a filler in a binder is completed; Fig. 3, a vertical section of the hopper and the frame on broken line 3 3 of Fig. 1, the other parts being shown in elevation; Fig. 4, a perspective view of the feed-cylinder and its case detached, and Fig. 5 a similar view of the feed-cylinder detached. Fig. 6 is a longitudinal vertical section showing the parts in their normal positions; Fig. 7, a View similar to that shown in Fig. 6, but illustrating the parts in the positions occupied thereby when the bunching-roller reaches the limit of its outward movement; and Fig. 8, a longitudinal section of a part of the machine, showing the bunching-roller in the position occupied thereby as it forms the bight wherein the bunch is rolled.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicates theside walls of the frame supporting the operating mechanism open at the front end a, A the rear wall of said frame, and A2 standards formed on side walls A, to the rear edges of which is hinged the hopper B, as shown at b. HopperB is adapted to be turned backward about said hinges for a purpose to be described.

D indicates slots or guideways extending diagonally downward and backward from the fronts of standards A2 into side walls A, and in the lower ends of slots D are formed semicircular seats d, wherein normally rest the spindles e of the bunching-roller E. Above and somewhat in front of said seats d is a cross-bar F, supported by side walls A and placed higher than the table F', located in front of the openings into slots D and supported in and between said side walls. The rear end of table F curves downward to form a lip f. To cross-bar F is secured the rear edge of the bunching-apron G, and the front edge of said apron is secured on the rear end of table F', which front edge of the apron is located adjacent to the rear edge of a transverse slot f in table F. The front end of apron Gr, from its front edge backward to the face of lip f, normally rests on table F and on said lip, and the body of the apron forms a pocket G' between the lip f and bunchingroller E when in its normal position. Behind and on a line with cross-bar F are two rollers H and H', and around these rollers passes an endless feed-belt H3, adapted to feed the binders to the bunching-apron, as is usual.

K indicates a revoluble feed-cylinder having its spindles K journaled in the meeting edges of standards A2 and of hopper B, the pillows of the journal-bearings being formed in the edges of said standards and the caps in the edges of hopper B, so that by turning the hopper back on its hinges b feed-cylinder K may be removed. In the periphery of feedcylinder K are a number of pockets K2, disposed lengthwise thereof and of different sizes, as shown. Inclosing feed-cylinder K is a cylindrical case comprising a stationary bottom L, having its ends rigidly secured in standards A2, and a cap L', hinged to one edge of bottom L, as shown at Z. In the to of cap L is a slot Z, through which the fillers v IOO the back edge of slot Z3 is formed a depending lip Z4. Case L L' prevents any displacement of the fillers in the pockets of the feedcylinder as they are carried from the feed to the discharge slots in said case and holds them in the pocket in the feed-cylinder until the same is in position to discharge into the pocket in the bunching-apron.

M indicates a crank-shaft journ'aled in the sides of hopper B, and from the crank m of said shaft is suspended a plunger M', having its stem m' .connected with said crank by a link m2. Plunger-stem m passes through a guide-slot m3 in a cross-bar M2, and the various parts are so disposed that the plunger is operated vertically above slot Z' of cap L'. The mechanism is actuated through a train of gearing on both sides of the frame. 0n one end of spindle K' of feed-cylinder K is keyed a gear-wheel N, to which power is applied through a crank-arm N', and on the other end of said spindle is keyed a gearwheel n. Gear-wheels N and n, respectively, mesh with idlers Pand p, located above them, and idlers P and 1o again mesh, respectively,

with gear-wheels Q and q on the ends of crank-shaft M. Gear-Wheels N and n also mesh with gear-wheels E and fr' on the ends of a shaft R', passing through the side walls A of the frame and between the folds of feedbelt H3', and the gear-wheelsR and r' mesh with p inions T and on the spindles of beltroller H, whereby said belt is actuated.

S indicates curved connecting-rods, the rear ends whereof are pivoted on gear-wheels R and t and adjacent to the peripheries thereof, and the front ends of said connectingrods are pivoted on spindles e of bunchingroller Of the wheels in the train of gearing just` described the wheels N and a, P and jp, Q and q, and R and r are all of the same diameter. With the beginningof each revolution fthe bunching-roller E is in its normal tresitionwith the pocket K2, that has just emptied' l a charge of filling into pocket G', locatedv tracted) position,.,a charge of iillling is supposed to be in pocket G' of bunching-apron G', with a wrapper W ini place to; be rolled about the same, the feed-cylinder K is inpo- -over slot Z2' of case L L", and the plunger Mfis raised, all as illustrated in Fig. 6. With the first half of the revolution of said wheels -bunching-roller E.advances,.rolling the wra-pper around the filling, as shown in Fig. 8, and discharging the completed bunch through slot j'of table F', feed-cylinder K is revolved until said pocket K2 is on top and beneath slot Z' of the cap of cylinder-case L L', and plunger M' is depressed and forces a fresh charge of illing into pocket K2. As said movements are completed the continuing revolution of the Wheels retracts the bunching-roller, a pocketl G' is again formed, the feed-cylinder revolves until pocket K2 empties another load intol pocket G', and the plunger is again elevated.

The pockets K2 of feed-cylinder K are of diftute one of said pockets for another, hopper B is turned back about hinges b until the feedcylinder is uncovered, and then said cylinder is taken from its position and again replaced with another of said pockets K2 in an operative position. If it is necessary to this end to change the relative positions of gearwheels N n on the spindles of the feed-cylinder, those gear-wheels can be removed by withdrawing split keys n' and then replacing the gear-wheels on said spindles in position to mesh with the adjacent gear-wheels of the train. Rim Z2 of slot Z of cylindrical case L L' prevents the entrance into pockets K2 of surplus filling material when the plunger is raised therefrom, and lip Z4 on the edge of slot Z3 of said case serves to direct the filling into pocket G' as it is discharged from the feed-cylinder.Y

In a shoulder in the lower end of the upper Wall of each guideway D is secured one end of a forwardly-projecting spring-plate V, the front ends of which are free and project over the sides of table F'. These springs are adapted to bear on the spindles of bunchingroller E as said roller is moved forward to hold the roller down to its place and yet permit it to rise should any unyielding matter be discharged into pocket G with the filler.

I do not confine myself to the details of construction herein shown and described, as it is obvious that many alterations may be made therein without departing from the principle and scope of my invention.
