SPECIFICATION forming part of Letters Patent No. 565,967, dated August 18, I896.

Application filed March 6, 1896.

' To all whom it may concern-j Be it known that I, JAMES H. DUNN, of the city and county of New York, in theState of -'New York, have invented a new anduseful Improvementin Oigarette-ld'achines,of which in-cigarette-fnachines' in which provision is foraccomplishing the abovemamed-results" and to. so arrange the operative parts that the *machine'will be compact and capable of be made for automatically separating a filler from a supply, rolling it within the wrapper," and trimming the rolled cigarette.

.' The object-is to simplify the mechanism ing attended without requiring special skill --f the operator. i I V In theaccompanying drawings, Figure 1 is Fig. 2 isa view in frontclevat'ionr Fig; 3 is 'a-viewin' vertical section from front to rear falongtheplaneof the linej3- 3 ofFig. 2; and :flFiglet' is a partial viewin s'ideelevation at iopposite'side from that shown iniFigi 1,

table, thence ,upwardly to a rod d means of a set-sorewd is located a permanent front wardly from the swinging Serial No. 582,030. (No model.)

d, fixed at one end to the front of the table D and extending thence overthe table and down into a depression (1 at the rear of the engaged with the frame A, where its opposite end is detachable from the machine,

renewal or cleaning,'by having its rear end provided with aloop (2 through "which. the.

removable rod 62 passes and which latter has its ends'engaged with the sides of the supporting-frame A. The opposite aprond is held fast between the underside of the table 1) and a clamping-block dfl'which maybe adjusted to and-from the table D by Above the depression d, in which apronfi'xed. The rolling-aprond is made readily I for purposes of end ofthe naturally falls into the position shown in Fig. 3 to receive the fillerfrom the supply, there I plate 7E, having s des e c, and a swinging top c -ef 8?, respectively, which,

together with the front plate E and its sides,

form a receptacle of, a blunt V shape at its bottom in crosssection for the charge of material which is to form the filler. The bottom e of this recepe tacle is located intermediate between the plane on which thetobacco whichis to form bottom, sides, and

the filler is fed and the rolling-apron and serves the purpose of' leveling the -ch rgewhich is to form the filler and permitting-it,

when the bottom 2 together-with the sides ,e, are swung away toward the front into the position shown in dotted lines,to fall in a compact evenly distributed mass into the, open loop in the apron: A spring a fixed at one end to the front of the plate E and at its opposite end to an arm eflprojectingfora hold the bottom and sides in their rearward top, e ,'s'erves to i 0 position to complete the receptacle for the filling-charged tobacco, and these parts are positively swung forwardly to drop the charge into the loop in the apron by means of a tripleverF fixed to a springactuated rock-shaft f, one arm of said lever being imposition-to engage a rearwardly-extending arm e on the swinging top e of. the receptacle to open the receptacle, and the other armjof which isin positionto engage an operating-nose g fixed IOO to reciprocate with the knife G which severs the charge of tobacco from the supply,

The knife G is mounted to reciprocate vertically in the front portion-of the frame A, and is operated by the free end of a leverg, pivoted to the frame A at 9 and connected by a rod 9 with the cam C on the shaft B. The cam C by its engagement with the connecting-rod g serves to lift the rod, and hence the lever g and hence the knife, until the laterally-extending stud or roller 9 on the rod g reaches the ledge on the cam, when the said rod and the knife G connected therewith are caused to suddenly drop by means of their own weight and the tension of the actuating-spring 9 connected with the rod g and with the fixed support upon the pedestal-zA.

The supply of material to form the fillers is fed to the knife G by means of an endless apron H, carried by drums or rollers h h mounted in the frame A. v The drum or roller h is operated by means of a ratchet wheel 7&2 fixed on its shaft, (see Fig. 4,) which ratchet wheel is operated upon bya pawl h, carried by a vibrating arm h mounted concentric with the axis of the roller h. The vibrating arm h has a slot-and-pin connection, of any well-known or approved form, with a connecting-rod 7L5, which leads to the cam C on the main shaft B, by which the arm h is vibrated at suitable intervals to advancethe apron H carrying the supply forward to be severed by the knife G.

The vibrating arm h is given a throw to move the pawl h the full distance which will be required for the greatest charge of filler that may be desired, and its effective action in turning the ratchet-wheel h is limited at pleasure to make the feed, and hence the charge,less than the greatest amount by means of a circular curved guard h", having a screw h engaged therewith and with the supporting-frame A in such a manner that the guard h may be slipped in one direction or another around the periphery of the ratchet-wheel k to protect more or less of the ratchet-teeth from the action of the pawl 71 as may be desired.

The drum or roller it has fixed to rotate therewith a gear-wheel h, which intermeshes with a gear-wheel b fixed to rotate with the compression-roller h which serves to compress the supply of tobacco into a flat compact sheet before it reaches the path of the knife G. The apron H is kept at a suitable tension by means of a tightening-roller I carried in the free end of an arm i of an anglelever pivoted to the frame A at i, the opposite arm 1' of said lever having engaged there with a set-screw 2' bearing at its free end against the top A of the supporting-frame, and so that by turning the screw in or out of the roller 1 may be forced toward or away from the apron H to tighten or loosen it.

The rolling-apron D is operated to roll the cigarette, after the filler has been dropped therein and the wrapper laid thereon, by the following mechanism: A vibrating arm K is pivotally secured at-its lower end at to the pedestal A and extends upwardly to a point to the rear of the rear portion of the apron D, where it is provided with a rocking compressor L, pivoted thereto. The vibrating arm Kis provided intermediate of its pivotal. point and the compressor with. alaterally-extending stud carryingan antifriction-roller 7a, which is located in position to bear against the cam G, which, as the shaft 13 is revolved, forces the arm K forwardly, carrying the presser L along over the rolling-table D." The arm is retracted by means of a spring 71: The compressor L bears normally against the belt, as shown in Fig. 3, near the pintle on which it rotates, but as it is advanced by the arm K it is rocked into an upright position (shown indotted lines in Fig. 3) by the engagement of an arm Z (see Fig. 1) extending an angle to the compressor L and preferably carrying on its end an antifrictionl-roller Z, which engages the track Z at the side of the table I),

so that the slack of the rolling-apron is taken up, and, when the arm K finally reaches the position shown in dotted lines in Fig. 3, the

pocket in the rolling-apron, which originally contained the filler in which the wrapper was finally'rolled around the filler, will be straightened out and the cigarette, having undergone its primary rolling to place the wrapper around the filler, will be ej ected from the apron into a downwardly-slanting passage-way m between a slanting fixed plate M and the face of the secondary or finishing rolling-apron m. The compressor L is retracted by means of a spring when its arm Z is disengaged from the track Z as the arm K is returned.

' The secondary or finishing rolling-apron is mounted upon drums or rollers m m, the latter having fixed to rotate therewith a sprocket-wheel m, which is connected bya chain m with the wheel 6 on the shaft B. The apron m is tightened and loosened, as may be desired, by means of a tightenerroller m, mounted in sliding boxes m carried by the hanger a, and adjusted by means of screws m As the cigarette passes from between the plate M and the apron m, it is received at or near its ends upon the curved edges n of stationary blades N, and while so supported its ends are trimmed squarely off by means of rocking blades 0, pivoted to the stationary blades N so that their cutting-edges shall IOO IIO

- rocking of the compressor L into an upright the station ry blade, as shown in" Fig; 3,'by-.

- means of a rodo, connectedat one end to the shank-of the blade and at" the oppositeend 7 provided with a laterally-projecting stud preferably provided with -an antifri'ction-r'olL,

brought into engagement with the cam,which again gradually forces the-blade O backout of the way of the next,-succeeding'cigarette.

by the rockingblades O, thecom'pletedcigarette falls from the knives intoa suitable re:

ceptacle, to be removed atpleasnre.

For'the purpose ofkeep ng the edges of the cutting-blades O and N free from gum and in condition to do' their work, perfectly,

I; provide for wiping off any foreign-substancewhich may accumulate uponthem as follows: Abrush Q is fixed to a suitableisupportoqextending forwardly from the arm K to; effect the primary rolling operation the brush- Q will beforced between thecntting blades located at the opposite ends of thecigarette and rubbing against them with 'sufli- 3 each'advance movement of the arm K.

The operation of the machine is "as follows! The parts being in the position shown in full lines in Figs. 1 and 2, as the cam C, is further rearward movement it will advance the sup: ply of. tobacco on the feed aprOn'H, sothat, p the charge will project in front of the path of the cutting-edge of the knife G. At this moment the cam 0 which operates the knife G, has reached the point where the rod 9 is permitted to drop from the periphery toward the center of the cam, and the blade G will fall,

the supply to form one filler. As the blade G descends, the nose g on its face will pass idly V .by the lever F. The return movement of the blade Gwill rock the lever F, by the engagement of the nose 9 therewith, in a direction to swing the sides and bottom 1 e e of the temporary receptacle for the filler toward the front, thereby permitting the charge within the temporary receptacle to fall into the pocket formed in the rolling-apron within the depression-d of the table. As soon as'the filler is adjusted on the rolling-apron, the

arm K, carrying the compressor L,is advanced by the cam 0', thereby closing the apron cl around the filler, and, the wrapper having been laid upon the belt d before the advance of the arm K, the said wrapper will be tightly rolled about the filler as the latter is carried along within the loop ir the apron over the stationary table D, Ti apron d, as soon as the rolling action begins, is tightened by the O forward to cut-,wliile the stud ois promptly a As the ends of. the cigarette are trimmed" and so arranged that as the arm K advances the primary rolling action is taking place on 'cient friction to thoroughlyclean them v at rotated to carry the rod- 7 to the limit of itssevering a suflicient qnantii y of tobacco from- ';position, and is ,so held until the -.a'm K reaches thelimit of its forward stroke, (shown in-dotted lines in Fig. 3,) at which moment the cigarette will'b'e ejected fromthe' loop'in the'apron" d into the passage-waybetween the secondary rolling-apron mand the plate M. After passing between the said apron and plate and receiving its finishing rollingyit will rest upon the stationary bladesN. As the arm K is advanced'it carries the brush Q forwardly into engagement with 1311613111111 -ming-blades, and as it begins its rearward movement while the cigarette isbeing rolled between the apron 'm and the plate M, the 8c brush is carried back from its wiping'post tion and the movable -trimming-blades'- O are promptly operated to trim the cigarette by" -I the action of the cam 0 which, just after the cigarette is dropped onto the stationary 8'5 blades, reaches a position which permits the.

rod 0 to drop from the. periphery toward 11 1 center of the cam under tensionof'the; springP. v. in The-timing ,of the parts issuch that while the. table D a previously-rolled 'cigaretteds' being trimmed by the blades N O and th'e supply isbeing fed rearward and a charge to form' the filler' severed and deposited in the temporary receptacle. The temporary re-jceptacle' is openedand the filler deposited in the pocket in the a'p'ro'nd just as the farm K reaches the limit of its-rearward stroke, and thepreviously g'ummed wrapper may be I placed on the apron-d on the tableD at any moment after the arm K' has receded to lay the apron d on the table and before it is advanced, so as to-bring the closed loopjn the apron into engagement with it.

-What I claim is-- I 1. The combination with. the feeding and rolling mechanism, the knife for severing the filler from the supply as it is-fed and means for operating the feeding and rolllng mech anism and the knife, of a atcmporaryrcceptacle for the filler, the said receptacle having a stationary front and a swinging bottom and .means under the control of the knife for swinging the bottom along the lower edge of U5 the stationary front to crowd the filler against the stationary front and finally permit it to drop into engagement with the rolling mechanism, substantially as setforth. v 2. The combination with the feeding an rolling mechanism,- the knife for severing the filler from the supply as it is fed and means for operating the knife, of a temporary 're-' ceptacle for the filler comprisingaperma'nent front plate, a swinging bottom, sides andtop 12 5 hinged to the front plate, aforwardly-extended arm carried by the swinging parts, a spring between the said arm and the permanent front plate for normaliy holding the swinging bottom closed,, a 'rearwardlyextended 13o arm, an operating-nose carried by the knife IOO the nose and to engage the rearwardly-extended arm for swinging thebottom forwardly to release the filler from the receptacle, substantially as set forth.

3. The combination with the rolling mechanism and. the trimming-blades, of a Wiper under the control of the rolling mechanism to free the trimming-blades from foreign substances and means for operating the rolling mechanism, the trimming-blades and the,

Wiper, substantially as set forth.

4. .The feeding mechanism comprising an apron for carrying the substances to be fed, a ratchet-toothed Wheel for actuating the apron, a Vibrating arm carrying a pawl for engaging the ratchet-Wheel and ag-uard consisting of a segment of an annular ring surrounding a portion of the periphery of the ratchet-toothed wheel and means for clam-ping the guard in diiferenr fixed positions able support, a feed mechanism, means for separatingthe filler from the supply advanced by the feed'mechanism, a primary rolling mechanism, a secondary rolling mechanism,
