SPECIFICATION forming part of Letters PatentNo. 537,097, dated April 9, 1895.

Application filed July 31, 1894:.

To aZZ whom it may concern: Be it known that 1, JAMES N. WOOD, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvementsin Cigarette-Machines; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention isan improvement in cigarette machines and consists in the novel features of construction and combination of parts hereinafter fully described, reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying my invention and said invention is fully disclosed in the following description and claims. A

charging the cigarette into the trimming mechanism and illustrating in dotted lines the operation of the trimming mechanism. Fig. 18 is an end View of the trimming mechanism.

The main frame of my improved machine consists of two vertically disposed side plates A A supported by brackets a a secured to a base plate A and braced by cross bolts (1 a.

B represents a tobacco feeding trough or chute which is formed in this instance in the shape of a trough having a bottom and sides, and is held fora portion of its length between the side plates A, A at an angle to the base plate A to facilitate the feeding of the tobacco. This chute or trough may be of any desired length and size which may be found desirable. The tobacco is fed positively along the trough or chute in this instance by a reciprocating feeding plate or rake B of any desired length which is of a width to work between the sides of the chute B and is disposed at an angle to the bottom of the trough or chute. This plate is provided at its forward end with laterally projecting studs 19 which engagerecesses in the sides of the chute B (see Fig. 5) and the said plate is reciprocated by a crank shaft B journaled in the side plates A, and provided with a suitable crank engaging a bearing 1) secured to the feeding plate B, as shown in Figs. 4 and 5.

The feeding plate or rake is provided on its under side with toothed portions having straight and inclined faces, adapted to feed the tobacco with the forward movement of the rake and to pass over the tobacco during its backward movement and said rake is curved upwardly at its rear end to enable it to take the tobacco readily.

By means of the trough B and rake B it will be seen that the tobacco is fed forward and compressed into a compactstream and projected from the delivery end of the tobacco trough or chute and I prefer to term the said trough and feeding plate the compressing feeding chute. Adjacent to the delivery end of the said chute is located the tobacco separatingknife or plunger 0. (See Figs. 5 and 6 particularly.) This knife is preferably formed in cross section as shown in Fig. 5 having its lower edge provided with a longitudinal groove and forming a sharp cutting edge on the side nearest the trough B.

The shank c of the knife or plunger C is pivoted to a bracket 0 secured to one of the side platesA (see Figs. 2 and 6) and the knife is held in its highest position by a spring c secured thereto and to a yoke c secured to the upper edges of the side plates A A. The tobacco separating plunger or knife 0 is depressed by the following instrumentalities: A vertical push bar 0 is mounted in guides secured to one of the side plates A adjacent to the bracket 0 to which the knife is pivoted, the lower end of said push bar having a friction roll engaging the shank c of the knife or plunger O as shown in Figs. 2 and 6. A knife operating lever c is pivoted upon a stud secured to the side plate A and has its forward end pivotally connected to the push rod 0 as shown in Fig. 2. The rear end of said lever is provided with a friction roll engaging a knife operating cam C secured on a cam shaft D journaled in the side plates A and extending through both of said plates. It will be noted that the knife operating cam C has two high grades 0 each of which produces a depression of the knife, the grade 0 depressing the knife farther than the grade 0 In operation when the grade 0 strikes the lever 0" the knife will be depressed and will out OK the tobacco projecting from the delivery end of the trough or chute B. The roll on the end of lever c then strikes the cut away portion 0 of the cam between grades 0 and c and allows the knife to rise so as to clear it from the tobacco and the grade 0 then depresses the knife again and carries it farther down causing it, by reason of its concave lower face, to act as a plunger and positively press the tobacco into the cigarette forming devices which will be held in position to receive the tobacco as shown in Fig. 5.

The cigarette is rolled or formed in what I term a rolling blanket E of flexible material secured at its rear end to a traveling roller E adapted to move in a curved path and passing forward over the pivoted rolling table E has its forward end secured to said table. In order to allow said blanket to be readily removed and a new one inserted I prefer to construct the roller E in two parts and to clamp the blanket between them as shown in Fig. 9,by means of screws, or I may employ any other suitable construction for this purpose. The table E is pivotally mount ed in the side plates A A and is provided on its under side with a detachable plate e between which and the bottom of the table, the forward end of the blanket E is clamped. (See Fig. 8.) The table E is thicker at its rear edge than at its front edge providing a broad rear side of considerable width between which and the roller Ethe rolling blanket is depressed to form the pocket to receive the tobacco filler. The table is also provided with a curved upper face which is given the same curvature as the path of the roller E. The roller Eis carried by two armsff projecting from a rock shaft F journaled in the side plates A A and the shaft of the roller E is provided at one end with a pinion e which gears with a toothed rack E secured to one of said side plates as shown in Fig. 3, so that as the roller is moved forward by the arms ff, the roller will be revolved rearwardly and caused to roll up the blanket E as it travels over the pivoted table E The rear face of the table E is given a slight inward curvature to accommodate the pocket of the rolling blanket, into which the tobacco is forced by the tobacco knife and said rear face meets the upper face of the table at a very. considerable angle. The required movements of the roller E are imparted to it by a roller operating cam E, on the cam shaft D, (see Figs. 3, 3 and 3 which cam engages a roller e on a sliding bar e having a slotted yoke a engaging the shaft D, the said bar having its forward end connected with one of the arms f of the rock shaft F. A spring e extends from the yoke e to a suitable stationarysupport which holds the friction roll e always in engagement with the cam E but in order to insure the positive retraction of the bar 6' and the roller E, the cam E is provided with an auxiliary grade a for this purpose. See Figs. 3 and 3 Forward of the tobacco knife or plunger 0 is a stationary shield or partitionu as shown to prevent tobacco from getting into proximity to the pasting devices and forward of this partition is the paste roller G having its shaft journaled in the side plates A. Motion is imparted continuously to this roller when the machine is in motion, in this instance from the cam shaft by the following means: A belt connects a pulley d on the cam shaft D with a pulley on a short shaft G provided with a pinion G engaging a similar pinion G on the shaft of the paste roller, as shown in Figs. 3 and 4. Above the paste roller G is the paste receptacle G which consists of a box open at top and bottom secured to the side plates A and having its sides adjacent to the paste roller made to conform closely to said roller so as to allow only a thin film of paste to be taken by the said roller. G is a weight fitting the interior of the paste box, for pressing the'paste down into engagement with the roller G.

The paper is fed into the machine from a paper roll H and is of a width equal to the length of the finished cigarette. The said paper roll is mounted upon a suitable drum, the trunuions of which engage suitable recesses in the ends of supporting arms hh secured to the side plates A A at one end of the same. In order to prevent the paper from being drawn off too rapidly and causing slack, I provide the arms h h with adjustable slides h h carrying a pivoted brake shoe 7L2 provided with aspring 72 for causing it to exert a certain tension on the paper roll.

The paper is fed into the machine by a milled or roughened feed roller I journaled in the side plates A A and. having its shaft provided with a ratchet wheel'iand a pivoted armiz" carrying a spring pawl i engaging said ratchet. The arm 7." is slotted and is engaged bya stud '5 projecting from the end of a lever 1' pivoted on a stud projecting from one of the side plates A and having a beveled portion in position to be engaged by a grade I on the cam E which operates the roller E, see Figs. 3 and 3, thereby feeding in sufficient paper to form a single wrapper at every operation.

In order to hold the. paper in engagement with the feed roller I, I provide a yoke I pivoted to the'side plates A A and carrying a milled or roughened pressure roller 11 which .is held in engagement with the feed roller I by means of a spring 2' having one end connected to a cross bar of said yoke I and the other to a cross bar 1' supported in this instance by the paper supporting arms h h. The paper is'guided after leaving the rollers I, '6 between stationary guide plates i 77, see Fig. 5, adjacent to whichis located the paper cutting mechanism for severing the paper web into individual sheets sufticient each for a wrapper. This paper cutting mechanism consists of the shears illustrated in detail in Fig. 2". Y r

K represents a horizontal stationary blade extending across the machine above the path of the paper and'provided with a bracket arm is secured to one of the side plates A and K is a movable blade pivoted to thestationary arm, the shears being set at an angle so as to cut in a direction perpendicular to the paper web, as illustrated in Fig. 5. A spring 70 secured to the movable blade and to a fixed stud on plate A (see Fig. 2) servesto hold the shears open and allows the paper to be-drawn between the blades. The movable blade is provided with a bearing surface 10 whichis engaged by one arm of a bell crank lever K pivoted on a stud secured to the plate A, (see side of the tobacco knife operating cam.

When this roll or stud K strikes the projection on the arm of the bell crank lever K the other arm of said lever is brought into en- .sive.

gagement with the bearing surface k of the movable shear blade therebv operating to close the shears and sever the paper.

In order to bring the severed end of the paper wrapper into engagement with the paste roller G, I employ a pivoted pasting flap or blade L. See Fig. 5 and Figs. 10 to 17 inclu- This blade L is carried by two arms I Z on a shaft Z journaled in the side plates A A in the positionindicated in the figures and when the paper is introduced into the machine it passes from the guide plates ibetween the shear blades K and K, then over the pasting blade L and then projects into the pocket formed by the blanket-E to receive the tobacco. As soon as the paper is cut off, this pasting blade is turned rearward on its shaft and this brings the upper edge "of the paper directly into contact with the paste roller and thoroughly pastes it. and 13.) The blade is moved far enough to carry the pasted paper beyond the paste roll and holds it in this position until it is drawn out of engagement with the pasting blade by the rolling of thecigarette, thereby preventing the pasted portion from coming'into contact with loose tobacco or anypart of the machine that could become gummed up in consequence, see Fig. 14, after which the blade L returns to its normal position.

The proper movements are imparted to the pasting blade 'at the proper time by the following devices: The shaftl is provided with an arm 1 outside of the plates A A. (See Fig. 2.) This arm is connected by a link Z with the lower end of a lever Z pivoted to astud Z and having a bearing surface l to be engaged by a stud or roll L on the inner face of cam G, the said bearing surface being long enough to hold the blade L inits rearward position untilthe paper is withdrawn from it by the rolling of the cigarette. A spring Z connected with the lever Z and with a stud on plate A restores the blade to its normal positionafter the stud L releases it.

p The operation of the cigaretteforuiing devices I have illustrated progressively in Figs. 11 to 17 inclusive and I will now describe the operation of forming a cigarette.

V The parts being in the positions shown in Fig. 5, the paper feeding devices are operated by their actuating devices to feed the paper into the machine until the end of the paper lies just within the pocket formed by the blanket E to receive the topacco, when a sufficient amount of paper wi l have passed the shear blades K K to form the wrapper for the cigarette. The tobacco knife is then operated. It descends far enoughto cut off the tobacco projecting beyond the end of the hopper or trough B, then rises as before stated to clear itself from the tobacco and then descends carrying the tobacco cut off down into the pocket formed in the blanket as shown in Fig. 11. At this point the roller Eis moved forward by its operating cam E into engagement with the rear side of the table E thus rear end below the plane of the roller E so as to allow the rolling operation to begin. The

proper movements are imparted to the table -by an arm on on a rock. shaft M mounted in (See Figs. 10

the side plates A A (see Figs. 2, 5 and 7) which has an arm m outside of the plates A A connected pivotally with an operating lever m having its rear end provided with a friction roll held in engagement with a cam M (see Figs. 1 and 1) by aspring m secured to the lever m and to a stud on the base plate. The cam M is provided with a grade indicated at 5 toimpart the desired movement to the table. The table is provided with an arm m to which a spring 071 is secured to hold the table in engagement with the arm m and to return it after it has been operated by said arm and said table is also provided with an arm on which engages in this instance a portion of the shaft F, to limit the forward movement of the table under the influence of the spring. The spring m holds the table normally in a position with the broad rear side in the path of the roller E and with the curved face of the table away from the path of said roller. Returning to Fig. 14, as soon as the table is tilted as previously described to bring the upper curved face of the table concentric with the path of the roller E the said roller is moved forward over the table E the roller being caused to revolve rearwardly during its forward movement by the rack and pinion before described thus rolling the tobacco within the blanket into cylindrical form and rolling the paper wrapper around the tobacco as shown in Figs. 14 and 15. As soon as the paper has been drawn far enough into ,the blanket E to disengage it from the pasting blade L, the said blade is returned to its normal position as shown in Fig. 15 and the paper will fly over into the position shown in this figure and lie upon the table E with the pasted portion uppermost. The continued forward movement of the roller E and consequent winding up of the apron as it moves forward draws the paper entirely within the blanket and rolls the pasted portion upon the wrapper forming a complete cigarette as shown in Fig. 16. At this juncture the forward end of the table E is given one, two or more (in this instance three) upward movements to compress the cigarette at the point where the pasted edge is rolled down (see Fig. 16) by means of three small grades indicated by 1, 2 and 3 in Figs. 1 and 1, thus insuring the accurate pasting of the wrapper. The further forward movement of the roller E carries it beyond the end of the table E and discharges the finished cigarette from the blanket E and in order to facilitate the discharge of the cigarette I preferthat the table E should be tilted up slightly by its operating cam as shown in Fig. 17, the grade of the cam M indicated at 4, being employed for this purpose. In order to trim the tobacco which is liable to project from the ends of the cigarette, I provide a trimming device best shown in Figs. 17 and 18, into which the cigarette is discharged from the blanket E. In this instance the trimming mechanism includes a trough N carried by two arms n n secured to a rock shaft N jonrnaled in the side plates, or I may dispense with a trough N and deposit the cigarette in two recesses in the upper ends of the arms 1?. it. To the arms 77. n I pivot a shear or knife blade at at each end of the trough, the said blades being mounted on suitable studs and held away from the trough N by springs 12 as shown. The rock shaft N is provided outside of the plates A A with an operating arm it, see Figs. 1 and 2, which is engaged by a stud on a lever n having its rear end in position to be engaged by the stud or roll L on the cam plate .0 to depress said arm and bring the trimming mechanism into the position shown in full lines, Fig. 17, to receive the cigarette. A spring n secured to a stud on the base plate A or other rigid support and to the lever n draws down said lever when it is released by the roll L and throws the arms not of the trimming mechanism forward into the position shown in dotted lines in Fig. 17. A cross bar N is supported by suitable arms secured to the side plates A A in position to be struck by the shear blades or knives n n as indicated in Fig. 17, thereby stopping them while the arms at it continue to move forward causing said knives or blades to cut off the projecting portions of the tobacco after which the cigarette falls from the trough N of the trimming mechanism and may be deposited in any suitable receptacle.

'The main driving mechanism of the machine is as follows: 0 represents the driving shaft which is mounted in bearings 0 0 secured to the base plate A and is provided with a driving pulley O to which power is applied for driving the machine. Upon the driving shaft 0 is a pinion 0' which gears with a gear wheel D on the cam shaft D and imparts motion thereto, as shown in Figs. 3 and 4. Upon the cam shaft D is agear wheel D gearing with a pinion Won the crank shaft B which imparts motion to the reciprocating feed plate or rake B.

The operation of the machine will be readily understood from the foregoing description.
