CIGARETTE-CUTTING DEVICE FOR CONTINUOUS-CIGARETTE MACHINES.

SPECIFICATION forming part of Letters Patent N o. 558,646, dated April 21, 1896i. Application filed May 17, 1895. Serial No. 549,645. `(No model.)

To all whom t may concern.-

Be it known that I, ROBERT IjlARDIE, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Cigarette-Cutting Devices for Oontinnous-Cigarette Machines, of which the following is a specification.

My invention relates to improvemeuts'in those devices which are used in machines automatically forming a continuous cigarette or a iller-rod inclosed by a paper wrapper to divide up the cigarette as it issues from the machine into appropriate lengths.

I will describe a cutting-off device for a continuous-cigarette machine in which are ernbodied the features of my invention, and then point out its novelty in the claims.

In the accompanying drawings, Figure l is a plan view of a cutter embodying' my inven tion. Fig. 2 is an end view thereof. Fig. 3 is a longitudinal section on the plane of the line 3 8 in Fig. l.

Similar letters of reference designate corresponding parts in all the figures.

As the present improvement is in no way dependent in its action upon the special form or construction of the cigarette-prod ucing machine to which it is applied, but may be combined with any cigarette-machine which produces a continuo us-tobacec-iiller rod inclosed within a wrapper, (the so-called continuous cigarette,) I have not deemed it necessary to illustrate such a machine, except so far as showing at A a portion of the framing of the machine upon which the cutter is supported.

B is a plate secured to the framing A and having two ton gue-pieces projecting from the main portion of the plate, to which tonguepieces there are secured the blocks a and a,

respectively. Fitted to the V-block a and adapted to move lengthwise of the continuous cigarette to and fro is a sliding carriage O. Similarly C is a carriage fitted to the V- block a.

Each carriage O and O carries a cutter, presently to be described, comprising a sharpedged disk. The cutters are duplicates of each other, each being alternately out of action and then in action, in which event the tobacco-iiller rod inclosed by the paper wrapper, or, in other words, the continuous cigarette, is severed. Each cutter has also during the act of cutting off a length from the continuous cigarette a simultaneous longitudinal movement with the latter.

After the length has been cut and the cutter has reached the limit of its simultaneous longitudinal movement. with the onwardlymoving' continuous cigarette issuing from the machine the former is withdrawn from the cutter, which thereupon returns to the opposite limit of movement, ready again to pass through the same series of motions.

I will now proceed to describe the construction which I prefer to employ to secure the reciprocation of the carriages, as well as the action of other mechanisms by which the operation as described is brought about.

The plate B is provided at I) with an extension, to which there is pivoted at CZ a double-armed lever E, whose ends are slotted and embrace studs e and e', extending from the carriages O and O', respectively.

F is a cam-shaft journaled in bearings secured to the framing of the machine. To it there is affixed a cam F, against the periphery of which bear two cam-rollers f and f. These cam-rollers f and f are journaled to st uds projecting from a sliding plate F2, working in suitable guides to permit of this movement. The sliding plate F2 imparts its motion to the lever E through alink F3, pivoted at one end to the lever and at the opposite end secured to the sliding plate in a manner to permit it to conform to the slight changes in direction caused by the turning of the lever E on its center without cramping. As shown, this connection may comprise a forked end formed on the link, to which there is secured a cross-pin f3, the latter having a bearing in the plate F2.

It is evident from this construction that a rotation of the cam-shaft FA will produce a vibration of the lever E, and consequently a reciprocation of the carriages O and O in opposite directions.

To the carriage O there is secured a pedestal Gr and to the carriageO a pedestal G. A sharp-edged disk G2, forming a cuttingdisk, is secured to a shaft by suitable means, the latter being journaled in pedestal G,while a similar disk G3 is similarly mounted in the IOO pedestal G'. These cutting-disks are rotated by a belt G"L driven by any suitable drum or pulley. (Not shown.) The cutting-disks will preferably be driven in opposite directions, and their motions at the adjacent portions of their peripheries will be downward.

H is the continuous cigarette formed by the machine, Il' being a portion of the iiexible belt common to this class of machines, from which the cigarette is withdrawn by the iin ger Zz.. A V-shaped trough H2 receives the continuous cigarette as delivered from the machine, it being carried by an arm ZL', extended from the framing of the machine.

A bent lever I is fulcrumed at the point z' to a boss of the carriage C, while to the boss of the carriage C' there is fulcrumed at the point z" a similar lever I'. These levers consequently are carried bodily with their respective carriages during their movements. During the bodilyT movement of each lever in the reverse direction to that in which the cigarette is moving its upper extremity is depressed below the cigarette by means presently to be described. During a movement in the opposite direction, however, the lever is elevated and the cigarette seated on a supporting-piece and carried across the periphery of its respective disk. In the present nstance the supporting-pieces are made in the form of plates, with their lower edges bent trough-shaped.

K designates the supporting-plate, secured in any suitable way to the upper extremity of the lever l, while K' designates the corresponding supporting-plate of the lever I'.

For securing the movement of the bent lever I upon its fulcrum-points I provide an arm L, pivoted at the point Z, whose upper extremity is extended laterally to form a bearing-surface Z', over which the lower extremity of the lever I slides as it is moved to' and fro by the reciprocation of the carriage C, Preferably a friction-roller Z2 will be j ournaled to the lever I and bear upon the surface Z'.

Rigidly secured to the arm L is a dependent crank L', by the movement of which the arm L may be swung about its fulcrum-point.

Mis an elbow-lever pivoted to a stud at m and having at the extremity of one arm a pin m', bearing against a friction-roller Z3, journaled to the lower portion of the crank L. The remaining arm connects by a rod M' with a stud bearing a cam-roller m2.

A cam is shown at M2 affixed to the shaft to move the lever I upward. The cam-roller l m2 is hung from the framing of the machine by a suspension-link f2.

At O is shown a spring-tongue secured at one end to the table C, while at its upper portion it bears against a pin o, extending from the upper arm of the lever, when the upper arm of the lever I is moved upward to lift the continuous cigarette from the bottom of the trough H2. Then the lever I moves downward, the spring-tongue O in following the pin 0 to assume its normal position will press against the continuous cigarette and prevent its retaining its elevated position to the left. A helical spring O' may be used for returning the lever I to its lowermost position.

The construction for securing the necessary movements of the lever I' may be similar to that already described, P being an arm pivoted at the point Z and having a laterally-extending bearing-surface p, upon which a friction-roller p', supported on the lever I', rests.

R is an elbow-lever fulcrumed at r and provided at one end with an upright pin r', which bears against a friction-roller p3, journaled at the lower portion of a crank P'. The lever R is vibrated through a rod R2, pivoted at one end to one arm of the lever R, and at the opposite end carrying a cam-roller r2, bearing against the periphery of the cam M2 under the influence of spring M3. The camroller r2 may be supported from the framing of the machine by a suspension-link f2.

Springs S and b" are suitably positioned to perform functions already described as pertaining to the springs O and O'.

I may add that the extremities of the supporting-plates K and K', from which the continuous cigarette passes, are arranged very closely to their respective disks, so that when the continuous cigarette is carried up across the face of the disk to sever the same there will be a true shearing action and an absence of bending action and consequent distortion.

I have shown a sharpening device for applying to each cutting-disk for keeping the same sharp. As the device for each disk is the same, when l describe the construction and position of its parts relatively to one disk it will equally apply to the other disk.

T is an arm extending from a shaft T', 1itted to bearings on the carriage C. The arm supports a plate t, to which there is pivoted at t a block T2. A fixed stud t2 enters an aperture in the block T2, it preferably being so secured therein as to be longitudinally adjustable. This adj ustability may be secured by providing the block with a longitudinal slot passing through into the aperture, a screw t2 entering a tapped hole in one of the side pieces of the slot to clamp the block upon the stud.

V is an emery or similar sharpening-wheel, slightly conical, and mounted upon the stud t2, its periphery bearing against the periphery of the corresponding disks. A cam-shaped .piece t bears against the block T2, it being rotated by a spindle t' to shift the emerywheel from the surface of the cutting-disk. A spring t2 is provided to move the emerywheel toward the cutting device.

Preferably each pedestal G and G' will be so mounted as to permit the cutting-disks to be moved toward and away from each other. This adj ustability I may secure by providing each shaft T with an arm V', having an arcshaped slot r3, through which passes a bolt IOO IIO

IZO

fut, whereby the pedestal may be adjusted to any position anduclamped.

It will be seen that the stud t2, upon which the sharpening-wheel rotates, is inclined to the axis of the cutting-wheel, as seen in both the side and the end view of the machine. Such a mounting of the sharpening-disks, in addition to its conical form, will permit it to bear for approximately its entire width of periphery against the cutting-disk, while at the same time it will be slowly rotated on its axis during the rotation of thc cutting-disk. These facts will preclude the formation of a shoulder or .other configuration of the sharpening-wheel tending to destroy the cutting edge of the disk.

The operation of cutting off the appropriate lengths from the continuous cigarette may be described as follows: The continuous cigarette issuing from the machine passes through and out of the trough Il?. Supposing now the parts are in the position shown in the iigures, in which the upper arm of the lever E is about to move toward the left, carrying the carriage C with it, the cigarette being lifted that the cutting-disk G2 may sever it. The carriage C simultaneously moves toward the right, the elbow-lever R being moved upon its pivot that the supporting-plate K may be depressed in a manner already described to carry it below the cigarette.

lVhen the upper arm of the lever E has reached the limit of its movement to the left, the elbow-lever M depresses the supportingplate K, the lever -R elevates the supportingplate K and presses the continuous cigarette against the cutting-disk G3 as the carriage C is moved to the left to sever another length from the continuous cigarette. These movements of the cutting-disks continue alternately throughout the operation of the device.

Having described myinventiomwhat I consider as new, and desire to secure by Letters Patent, is-

l. The combination of longitudinally-reciprocating oppositely-mounted and oppositclyfor reciprocating the carriages, and mechan- I ism for causing a relative movement of the cigarette and oneV cutter toward each other while the supporting-carriage is moving forward, and then a relative movement of the cigarette and the other cutter towardeach other, substantially as spcciied.

3. rlhe combination of longitudinally-reciprocating oppositely-mounted and oppositelymoving carriages, the forward movement of each carriage corresponding to the forward movement of the cigarette issuing from a continuous-cigarette-forming machine, cutters mounted upon the carriages, supportingplates for the cigarette carried by the cary riages, a lever for reciprocating the carriages and levers for causing a movement of first one plate, with the cigarette, and then the other plate, toward its respective cutter, this movement corresponding with the forward movementof the respective carriage, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
