CIGAR-WRAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 496,453, dated May 2, 1893.

Application filed April 8, 1892. Serial No. 428.337. (No model.)

.To a/ZZ whom it may concern:

Be it known that I, FREDERIC STILEs, a citizen of the United States of America, residing at Binghamton,in the count-y of Broome and State of New York, have invented certain new and useful Improvements in Cigar-Trapping Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

In a machine for wrapping and finishing cigars it is desirable that the rollers should be adapted to conform to the shape of the cigar operated upon, and should be adj usted to different sizes and shapes of cigars mechanism should be provided by means of which the wrapper may be fed evenly and without wrinkling; and that the machine should'also finish the cigar by completely wrapping the head without requiring special hand labor for Further, it is desirable that the machine should be so constructed that it may be opened to receive the bunch and the stopping and starting also should be controlled by a treadle so that the hands of the operator may be left free to manipulate the material. It is also desirable in some cases to provide a machine capable by adjustment and by replacing some of the parts to wind either right hand or left hand wrappers. In the machine hereinafter described and in which my invention is included I have sought to accomplish these objects and I have hereinafter set forth the particular constructions and combinations in which my invention con- Sists.

The machine is illustrated in the accompanying drawings, in which:-

Figure l shows a rear elevation of the machine. Fig. 2 represents a plan view of the machine. Fig. 3 shows'a section on line :2c-:c of Fig. 2. Fig. 4 is a longitudinal section of one of the rollers. Figs. 5, 6 and 7 are perspective views of details.

In the drawings, A, A represent the end pieces of the frame of the machine.

A is a plain casting in the form of a standard in which the rods or barsB are fixed connecting it to the end piece A, and in which also are the bearings of the various shafts.

It is provided with a horizontal slot in which is located the block a, forming the bearing of the left hand end of the shaft b; this block slides in the slot and is provided with a stem extending lengthwise of the slot through a cap piece c. The end of it is threaded and is provided with a nut d having a milled head. A coiled spring e, is placed on `the stern one end bearing upon the cap and the other end upon the block so as to hold the block normally pressed against the inner end of the slot. may be turned to the front against the press ure of the spring in order to adjust the shaft b. The end piece A has a similar slot provided with a block, stem, spring and nut marked by the same letters. By means of these either end of the shaft h, or both, may be adjusted in horizontal directions. The shaft b, carries one of the rollers by which the cigar 'is held and turned. The main roller is upon the shaft f, which has'fixed bearings in the end pieces A, A. The right hand end is provided with a pinion h, which meshes into a pinion t' onthe driving shaft I. This shaft is mounted in bearings in an extension A2 of the part A, these parts being preferably cast in one piece. a loose wheel'k, which may be held to thc shaft by means of a clutch Z, splined on the shaft and mountedin` the upper-end. of abell crank lever m, pivoted` on the eXtensionand movable by connections with they' treadle. The shaft b is driven by a pinion b meshing with the pinion on the l shaft I. The vertical slot of the screw 3 is shown in Fig. 2. The position of the screw 4 is shownin Fig. 3, and the vertical slot is in part shown above the screw. The third roller is on the shaft g, which is mounted in a swinging frame, and this shaft has a pinion g also in mesh with the pinion t' when the machine is in working position. The shaft g is mounted in a frame H; the bearings in which it turns are vertically adjustable on this frame. These bearingsare marked l and 2 and their lower eX- tensions are held by set screws 3, 4, in vertical slots in the frame so that they maybe slightly raised or lowered on the frame H.

6o By means of the nut the bearing block rlhe shaft is provided with The bearing 2 has an arm 6 extending laterally and carrying a third bearing to support the shaft g the end of which carries the pinion.

The frame H has pivoted sockets '7 and S on its lower part, which are pivoted upon rods m, n, set adjustably in holesinthe end pieces and held by set screws 9 and 10. The frame II rocks on these rods so as to move the roller upon the shaft g toward or from the cigar when the latter rests on the roller on main shaftf. This movement may be for the purpose of adjustment, or, when carried to its full extent for the purpose of opening the machine to receive the bunch orto drop the finished cigar. To effect these movements and to regulate the normal position of the roller, I have provided an arm 13 on the frame Il in which is a regulating screw 14: arranged to bear on a stud 15 set in the end piece A. This regulating screw has a jam nut 16 to hold it securely in place. The frame is normally held inward by a spring 17. Another arm 18 on the frame H is provided with connections which lead to a treadle similar to that which releases the clutch of the driving wheel so that the machine may be arrested by one treadle and opened by the other.

lt will be observed from the description above given of the frame H and its connection, that it may be shifted laterally, and to permit this the pinion g is held on the shaft g by a set screw, so that When the frame H is shifted in that direction the shaft may pass through the pinion without displacing it. This adjustment laterally is required when the apparatus is changed from a right hand Winding to a left hand Winding as hereinafter more fully explained.

The rollers on the shafts heretofore explained, are marked respectively B and F and Gr. They are arranged coterminously, and the two upper (B and G) in such relation to each other and to the lower on which the bunch rests, that it is held in the grasp of the rollers, and is turned as they revolve, and in the turning the wrapper is wound upon the bunch.

The particular construction of the rollers is hereinafter described. To secure the even and unwrinkled application of the Wrapper (which is of prime importance), l provide a feed plate having a guiding edge, fitted to guide the Wrapper to the bunch. This edge is therefore inclined to the axis of the bunch,

as it lies in the grasp of the rollers. The plate is shown at P. lts front rests upon the flange p of a bracket ],held on a bar Q which is supported upon the end pieces A, A. The feed plate is curved as shown in the sectional view Fig. 3, and is held to the bracket by set screws set in the bracket and passing through slots in the feed plate said slots being in line of movement to and fro the rollers. The

[it of the set screws in the slots is loose so that the feed plate may be adjusted more or less at either end, to conform to the particular shape of the cigar operated upon. The plate curves over the roller B and down close to it, but not in contact with it.

AIn the drawings the machine shown is arranged for right hand winding.

The left hand end of the plate which is opposite the tuck end of the cigar, is farthest back, and does not, in the form shown, extend quite over the roller B. It inclines forward toward the right to follow the taper of the cigar toward the head thereof. The guiding edge is rounded and is approximately in the form of a rib, the plate in front of the rib being depressed, so that the wrapper, as it is drawn over the rib or edge bears upon it alone, and does not bear upon the plate in front of the rib.

The incline of the guiding edge is designed to be approximately at right angles to the line of the wrapper in the process of Wrapping the bunch. At the most advanced end of the feed plato, which in the form shown,is the right hand end, is an arm R carrying the header r. This arm is held to the bracketby a set screw passing through slots in the arm of the bracket into the bar. The bracket at the other end is also held by a slotted connection so that it may be adjusted laterally and held in place by the set screws. The arm R lies up against the plate and is flush with its upper surface forming practically a continuation of the plate, and the guiding edge is prolonged in the form of a finger as shown at U, over the front and downwardly turned end of the arm just above the header. The header has a cone shaped cavity litted to receive the head of the cigar; it is open on the upper side and the front face of the arm curves continuously down into the cavity of the header. The lip son the opposite side is curved down, with a groove t extending from the tip of the header cavity down to the end of the header. The end of the guiding edge which projects from the arm and above the header cavity is curved down also so that the fingers of the operator, pressing upon the tip of the Wrapper may follow it and retain the touch upon it quite down to the cavity, and by this construction the operator is enabled to guide the wrapper close down tothe header cavity Where it is received, and by the cavity itself accurately wrapped upon the head, as the Wrappers are cut by suitable dies to tit the size and shape of the bunch operated upon.

The mechanism above described completes the wrapping and finishes the cigar with accuracy and certainty.

As has been explained, the guiding edge and the rollers B and Gr may be adjusted accurately to conform to the shape of the bunch to be wrapped. The wrappers having some elasticity may be held over the guiding plate and permitted to move over the guiding edge perfectly smooth, and may bc laid upon the bunch without Wrinkling, even if the guiding IIO edge be not accurately parallel with the side of the cigar; but it is designed to conform substantially in its inclination to the shape tip.

of the cigar, and the extended part which projects across the face of thearm and over the header continuously guides the wrapper to the the upper edge being slightly curved and the yss face Vmade smooth and slightly rounded to bear gently against the side of the bunch and to smooth the wrapper as it is wound upon the bunch. Being held by' a single screw it may be moved forward and turned so as to conform accurately to the shape of the bunch, and when adjusted properly upon the plate 2O it is carried by the frame, and the amount of pressure applied to it by the spring is regulated by the adjusting screw which regulates the frame II.

The rollers consist of flexible sleeves preferably of rubber, or some of its compounds which are held upon the shafts by means of thimbles 25. These have upon them collars 26 and the ends of the thimbles are inserted into the ends of the roller sleeves 28 being fitted to hold the roller sleeves by frictional contact. The thimbles are set adj ustably upon the shafts and held by set screws so that by pressing them together or extending them the shape of the roller may be modified. As the rubber ts tightly over the thimbles the air is held therein and a free yielding roller is produced. tightly fittin g supplemental tapering roller or spool 28 which may be slid into or out of place. When it is brought into place it is in position to bear upon the tuck end of the cigar. This is used when the tuck end is extended and reduced. The extended tuck end would rest upon the other side upon the supplemen- V tal roller or spool 29 on the shaft f.

It will be observed that in Fig. 4 the front rollerB is placed in a lower plane than the rear roller G and that the feed plate is also lower and does not cover the space between these two rollers. This arrangement while it does not interfere Vwith the gripping of the rollers upon the bunch at the same time permits the operator to see the cigar in the process of wrapping, so that if he should fail properly to lap the wrapper, he can arrest the machine by motion of his foot and readily correct the mistake. The pinions on thek ends of the adjustable shafts are formed with teeth Upon the shaft b, is set a of sufficient depth to allow the required movement of adjustment without losing the mesh.

The bunch rests on the roller F with its end on the supplemental roller on the same shaft. The roller B rests against the frontside, and the roller G on the rear, a little above the center. The bunch is thus held in the grip of the rollers, but with the upper side exposed. VIn the machine as shown, the rollers turn in the direction of the arrow. The wrapper-folded and tucked on the tuck end, the bunch placed7 and the machine started, it rolls the bunch into or upon the wrapper, after the manner of hand wrapping, and the wrapper is guided and smoothed in its application to the bunch by the guiding edge. Each fold or wrap, as it is formed, is also smoothed and press/ed by the wiper, as the bunch turns up on the other side but the head of the wrapper is thus smoothed and pressed by the cavity of the header which is made to conform to the shape of the bunch, and may be removed when the form of bunch is changed.
