ClGAR-BUNCHING MA CHINE.

SPECIFICATION forming part of Letters Patent No. 572,170, dated December 1, 1896. I

Serial No. 541,994. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. IsLEY, of Jersey City, county of Hudson, and State of New Jersey, have invented a new and Improved Oigar-Bunching Machine, of which the following is a full, clear, and exact specification.

My invention relates to improvements in cigar-bunching machines, which improvements have for their object simplicity in construction and action, durability, and economy.

Another object of the invention is to regulate the variable tension of the bunchingapron, so that it will not wrinkle or gather upon the rolling-table in front of the roller, for the reason that when so wrinkled the apron will not perform to a satisfactory degree the function for which it is intended.

My invention is illustrated by the accompanying drawings, in which Figure 1 is a side elevation of my invention, showing rolling-table support, partly in section. Fig. 2 is a front elevation of the machine. Fig. 3 is a sectional view taken on the line .1: 00, Fig. 2. Fig. 4 is a plan View of my invention, the parts being in the position indicated in Fig. 3; and Fig. 5 is a side view of a detailed portion of the invention.

Similar letters refer to similar parts throughout the several figures.

A is a bench or table of any desirable pattern. Mounted over an opening in said ta ble is a framework or base B, upon which the moving parts find their support, as hereinafter described. Projecting upwardly from said base B is a standard D. In the upper portion of this standard there is provided a concavity or depression E. Projecting from one side of this concavity or depression and supported, preferably, by the said standard D is a rolling-table F.

G is a tension-frame pivotally mounted in the lower part of the base B on suitable journal-bearings H H.

I is an adjustable roller revolubly mounted at the upper end of the tension-frame G.

J is a jam-nut by which the said roller I is tightened or loosened, so that the same may be permitted to roll freely or held stationary as desired.

P is an apron one end of which is by preference fixedly secured to the forward under edge of the rolling-table F, while the other end is supported and carried by the adjustingroller I. The normal position of the shaping-frame is indicated in Fig. l, in which position it is shown as resting against a stop Qon the framework orbase B. The normal position of the tension-frame is shown in the same figure, in which it is seen to rest against the opposite side of the said stop Q. The said shaping and tension frames seek the normal position by the action of the counterweights N and L, respectively, and when in this position the bunching-rollers O O repose on the side of the concavity or depression opposite the roll-table, leaving the said concavity or depression E open, so that a bight of the apron may be pushed thereinto.

R is a crank-arm secured to and projecting from the journal H of the tension-frame G.

S is a cam secured to and projecting from the journal N. The journals H and N are substantially parallel, and the cam S is adapted to move in the path of the crank-arm R, so that when the shaping-frame is moved so as to carry the bunching-rollers O 0 over the rolling-table F the said cam S will contact with the crank-arm R, causing the tensionframe G to swing back into the position indicated in Fig. 3, the cam and crank-arm;

when the parts are in that position being indicated in Fig. 5, causing the bunching-apron P to tighten to the proper degree.

In operation a charge T of tobacco is first placed on the bight in the apron which rests in the concavity E. A binder U is placed upon the rolling-table, so that its forward edge by preference projects nearly to the edge of the concavity E. The shaping-frame is then moved, the bight in the apron is closed by the bunching-roller, the tension-frame is thrown back by the fixed and positive action of the cam S against the crank-arm R, and the charge T is carried over the rolling-table F, taking up the binder as it advances. At the forward end of the rollingtable the pocket or bight in the apron P is opened and the finished cigar-bunch is discharged into a suitable receptacle. A handle V or the ordinary foot-treadle may be provided as a medium by which the shaping-frame may be moved.

It will be observed that the essential feature of my invention consists in the novel means herein described to provide a fixed and positive tension to the apron at the proper instant. I am aware that heretofore it has been common to make use of a spring whereby the tension-frame is retracted, but in all such instances the normal position of the tensionframe is away from the rolling-table, causing a constant tension of the apron, which is overcome by the intervention of separate mechanical means at intermittent periods. Furthermore, the tendency of the spring is not as positive as the action of the cam, which cannot yield. In machines of this character where the resistance offered to the bunchingroller by the apron varies it is desirable that a positive means be atforded'whereby a uniform movement may be given to the tensionframe. Furthermore, in operation when the cigar-bunch is discharged from the machine the parts resume their normal position automatically, thereby affording sufficient time for the operator to take the cigar-bunch out of the receptacle and place it in the separate mold commonly employed. In utilizing this invention there is no tendency for the apron to wrinkle or gather up in front of the bunchi'ng-roller as it is advanced over the rollingtable, for the reason that the tension-frame cannot yield to permit the slack which must necessarily be present to permit the apron to so wrinkle or gather up.

To accommodate the machine to various sizes of bunches, the adjusting-roller which carries one end of the bunching-apron P may be loosened and set so as to give the proper slack thereto. If desirable, also bunchingrollers of varying shapes and sizes may be substituted. It is obvious that the cam S and the crank-arm R may be readily modified as desired, and a roller might be added to the end of the crank-arm to reduce the amount of frictional contact between the parts, if found expedient, without departing from the spirit of my invention. If desirable, springs could be substituted in place of the counterweights above described.

I am aware that it is not broadly new to combine in a cigar-bunching machine a rollin g-table having a concavity therein, a bunchdium of the crank-arm as the bunch is being rolled.

Having thus described my invention,what I claim, and desire tosecure by Letters Patout, is-

1. In a cigar-bunching machine the combination with a rolling-table having a concavity in rear thereof, of a pivotally-supported tension-frame normally held in rear of and adjacent the said concavity, a bunching-apron secured at one end to the upper portion of the tension-frame and at its other end to the forward end of the rolling-table and a pivotally-supported shaping-frame also normally in rear of said concavity but in front of the tension frame, and means carried by the journal of the shaping-frame for positively engaging the tension-frame and moving it in the direction opposite to the direction of the shaping-frame; substantially as described.

2. In a cigar-bunehing machine, the combination of a rolling-table, a concavity in the rear thereof, a bunching-apron, a pivotallysupported tension-frame supporting one end of said apron, means for normally causing the tension-frame to swing toward the rear of the rolling-table, and a crank-arm secured to the journal of the tension-frame, with a pivotally-supported shaping-frame carrying a bunching-roller, a cam secured to the journal of said shaping-frame and adapted to operate the tension-frame through the medium of the crank-arm, substantially as and for the purpose specified.

3. A cigar-bunching machine consisting of a pivotally-mounted tension-frame adjustably carrying the rear end of a bunchingnal-bearing of said tension-frame, in combination with the rolling-table and bunching: apron, and a pivotally-supported shapingframe carrying a bunching-roller toward its upper end, and carrying a cam upon its journal-bearing adapted to engage with the crankarm on the tension-frame to cause the upper end of said tension-frame to move rearward away from the concavity in the rear end of the rolling-table, for the purpose of affording tension to the said bunching-apron during the entire process of rolling the bunch and with the counterweight located on an arm projecting from the tension-frame journal-bearing and operated as described.

4. In a cigar-bunching machine, the combination of ;a pivotally-supported tensionframe, a rolling-table having a concavity as 1 15 apron, a crank-arm'projecting from the jourdescribed, a bunching-apron, and means to cause the said tension-frame to normally swing toward the concavity in the rear of said rolling-table, a stop Q, with a pivotally-supported shaping-frame and means to cause the same to normally swing toward the rear of the rolling-table where it is checked. by said stop Q, a bunching-roller carried by the shaping-frame, and with means as described including a cam and crank-arm for causing positive and cooperative action between said tension-frame and shaping-frame so that as said shaping-frame is moved toward the front of the rolling-table the tension-frame will be moved in the opposite direction.

5. In a cigar-bunching machine, a piv0ta1lysupported tension-frame G, an arm K projecting from said frame G, counterweight L, crank-arm R adjustably carried by said arm K projecting from said tension-frame bear ing, and an adjusting-roller I supported by said tension-frame, in combination with a pivotally-supported shaping-frame M, a bunching-roller 0 carried thereby, arm N projecting from said shaping-frame axle and carrying a counterweight N with a cam S, a stop Q on said framework for checking the frames G and M, and a concavity E in the upper end of said framework, and with a rolltable and apron P, one end of which apron is secured to the forward end of said roll-table, the other end being secured to the said adj listing-roller I, substantially as described.
