CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent-No. 259,090, dated June 6, 1882.

Application tiled August 8, 1881.

To all whom it may concern:

Be it known that we, JAMES BURNS, of Brooklyn,E. D., State of N ew York, andALEX- ANDER yBUOKMAN, of Schedack Depot, Rensselaer county, State of New York, have invented an Improvementin Cigarette-Machines, of which the following is a specification.

The present improvements are made for siniplifying the machinery for making cigarettes.

We iutrod uce a strip of paper, and as it passes into the machine theadhesive material is applied near one edge to the under surface. This becomes the outside of the wrapper. The paper is folded up int' the shape of a trough, the tobacco, in the proper condition, is passed in between 'guide-plates vand fed along by4 a wheel with pins in its periphery and packed iutoithe cigarette-former, the pressure of the pins against the tobacco 'causing it to move along through the former and draw with it the paper wrapper. This insures uniformity in the cigarette, because it only moves as fast as the tobacco is properly packed and moved along. The paperis closed up around the former and tobacco, the plain edge lapping upon the gummed edge, and the parts are held together while moving along on a belt, and then the strip is cut off in proper lengths by a vibrating knife. In the drawings, Figure l is a plan of the machine with the holding-bar removed. Fig. 2 is an elevation, part of one pulley and a connecting-rod being removed for greater clearness. Fig. 3 is a side view of the lling-wheel and section of the bed-former and adjacent parts. Fig. 4 is an elevation ofthe former, and Fig. 5 a plan of the former, in larger size, and adjacent parts below the line x x ot Fig. 3. Fig. represents the paper and the guide-plates and part of the hopper. Fig. 7 shows the lower edgeof the feed-wheel as' it is delivering theV tobacco into the paper trough and former. Fig. 8 shows in section the former, with the paper ready to be folded over the tobacco-aud the stripper-grooves and toothed wheel. Fig.

45 9 shows the first edge of the paper as pressed down toward the tobacco. Fig. 10 shows parts that consolidate the tobacco laterally and press the second edge down upon the ad hesive edge. Fig. 11 is a side view of the cut- 5o ter and section of the bed-slide. Fig. 12 is a paste.

face viewof the same. Fig. 13 represents the pulleys and gearing. Fig. 15 is a cross-see tion, in larger size, of the holdin g-bar and belt.

The paper c. is supplied from a reel of convenient size, and the width of the strip is such that it will pass around the tobacco and lap sufficiently to be made to adhere b'y glue or The roll of paper a is supported by an adjustable bed with standards a upon ythe bed A of the machine. The paper passes over the roller b and down beneath the guideroller c. The roller bis supported by an adjustable bed and standard, and is made in two parts, there being a disk, 2, of the same size as the roller b, on the same shaft, adjacent to but not touching the main roller b, and this` disk runs in a trough, d, containing mucilage, paste, or other suitable adhesive material. This disk applies to the under surface of the paper aline of adhesive material close to the left-hand ed ge.` The terms right77 and left 7 hand will be used for convenience, the presumption being that the person is standin g at the end of the machine and looking in the direction in which the cigarette-paper and its tobacco are being moved along. The edge of the disk 2 may be notched, and there is a scraper to remove the surplus gumfrom the edge of this disk. After passing below the guide-roller c the paper rests upon a guide-bar, e, that lies dat on the bed f and extends along as far as the end of the former, hereinafter referred to. This bar is a little wider than the diameter of the complete cigarette; hence the gummed portion of the paper is kept up Off the bedfand does not come into contact with anything.I In this condition the paperis moved along beneath'the stationary guide-plates c' c', that extend downwardly below the hopper g, into which hopper the tobacco is placed.

There are folders 3 4 beyond the guide-plates c c' havin g rounded or inclined ends, that turn up the edges of the paper without touching the gummed portion. The folder 3: is L-shaped, the bottom part being the same thickness as the guide-bar c and continues beyond it. The folder is attached to the bed by screws, so that it can be removed for cleaning, if needed. These guide-plates c c extend to the feed-wheel h, and'their forward ends are segmental to fit IOO against the periphery of this wheel h. There are numerous pins ou this feed-wheel h., preferably arranged in two peripheral rows, as seen in Figs. 7 and 8. These pins serve to draw down and force into the trough-shaped paper and cigarette former the tobacco as it is fed from the hopper by hand to this wheel h. These pins are not long enough to touch the paper as it lies upon the folder 3.

The cigarelte-former i performs a double duty--of holding down the tobacco, stripping it from the pins, so that said pins will draw out of the tobacco at the ascending side of the feedwheel, and also of a guide over which the edges ofthe paper are folded down to their position.

le remark that the feed-wheel his to be driven by any'suitable means. We have shown the driving-pulley k and cross-belt from pulley l to the pulley l as a convenient mechanism.

The forincrt' has two plates, 6 and 7, extending back at each side of the feed-wheel h, and also a segmental surface at 8, corresponding to the curvature of the wheel h, and in which are slots j ust wide enough to allow the teeth of the wheel h to pass, and thereby the former strips off and retains beneath itself and within the trough of the paper the whole or almost all the tobacco as the teeth draw away from the tobacco. W'e, however, employ a stationary brush at m to remove any particles of tobacco. These fall into the box u and are removed by hand. The guard o, above the toothed feedwheel h, serves to prevent injury to the attendant by contact with the feed-teeth.

The general form of the cigarette as it is made is square, and the former fi, being above the tobacco, holds it down within the trough of paper, and the consolidating-wheels 14 compress and consolidate the tobacco laterally, and in so doing` the edges of the strips of paper are brought to a position where rst one side of said paper can be folded down and then the other folded to lap upon the first-named edge and the adhesive material.

There is a thin plate, s, that extends to the rear of the former t', and the finger r turns the gummed edge of the paper inwardly over this plate s, and then the other edge of the paper is turned inwardly over the gummed edge by means of the presser-arm t, so that the two edges adhere and hold the tobacco, and the long tube of ,paper filled with tobacco .runs along in a groove in the under face of the holding-bar c and upon the elastic belt u, by means of which the paper is kept in place a sufficient time for the gum to set and hold the folded edges together.

The revolution of the wheel his one force that causes the paper tube to move along, because this wheel runs at a greater peripheral speed than the movement of the paper tube, so as to pack the tobacco into the paper tube, and by the pressure of the teeth against the tobacco cause the same and the paper tube to move through the machine. The belt u, however, also has a motion given to it by the gears l5, 16, and 17, that rotate the belt-pulley u', and the rear belt-pulley, a2, is also revolved by the belt 18 and pulleys 19 and 20, so as to prevent strain on the elastic belt u. The gearwheel 17 and pulley 19 are preferably made as one. The gear-wheel 15 is removably secured on the driving-shaft and can be replaced by a larger or smaller gear when it is desired to increase or diminish the speed of the belt n, and the stud for the gear-wheel 16 is adjustable in a slot, so as to be placed to suit the size of wheel 15 made use of. The wheel 15, as containing a greater or lesser number of teeth, causes the cigarette to be cut in different lengths by giving more or less motion to the elastic feed-belt u between each reciprocation of the knife. This elastic belt a is supported at intervals upon rollers q, the object being to hold the cigarette into a groove that there is in the under edge of the supporting-bar o, in which the cigarette moves along by the joint action of the belt a and the'feeding in of the tobacco by the wheel h.

The cigarette tube is cutoff in suitable lengths to form the cigarettes. This is acco|nplished by means of the reciprocating cutter stock w and cutter 21.

The elastic belt u has pieces of rubber a cemented to its surface, as seen in Fig. 14, and between which a groove is formed, in which the cigarette travels, and the edges of these pieces grip the sides of the cigarette and compel its motion to be more certain and steady.

The bed 20 is in guideways 22 on the table or frame A, and the cutter-stock w slides in these guideways 22, being moved back and forth by the crank-pin 24 and connecting-rod 25.

The wheel 3l on the driving-shaft, to which the connecting-rod 25 is secured, is slotted to adj ust the connectin g-rod 25, in order that more or less motion may be given the cutting devices when it is desired to cut extra long cigarettes.

The cutter 21 is held in guides on the stock w, so that it may slide vertically, or nearly so. We prefer to make the cutting-edge or concave, so as to cut oft' the cigarette-tube without tending to open the gummed lap. The spring 26 acts to lift the cutter and the switch or cam 27 forces it down. This switch-cam is pivoted at one end to the stationary bracket w', and the other end is kept np by a spring, 28. At one side of the upper end of the knife 2l there is a pin, 30, projecting. As the stock and cutter draw back toward the feed-wheel h the spring 26 holds the cutter out of the way of the cigarette, and the pin 30 passes above the Switch -cam 27, depressing the same. Then the switch springs up. During this time the cutter is above the cigarette and untouched thereby. When the reciprocating cutter-stock moves in the other direction at about the same speed as the cigarette is being moved the pin 30 under runs the cam-switch and the cutter 21 is forced down, and the length for the cigarette is cut ofi". This is accomplished without injuring the paper tube, because the cutter IOO IIO

stock is moving at about the same speed as they cigarette. Y The cigarette drops down through a hole in the bed into a suitable receptacle. The cutter 21 is thrown up by its spring 26 as soon as the pin on said cutter passes beyond the end of the switch 27, and it returns above the switch, as aforesaid. v
