To all whom, t may concern:

a citizen of the United States, residing at New York, county of New York, and State of New` York, have invented certain new and useful Improvements in Cigarette-Cutting Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relatesfto that class of cigarette-machines in which a continuous cigarette-rod is formed, which is then cut into suitable lengths to form the cigarettes.

The object of my invention is to improve` the cutting mechanism of this class of machines 3 and to this end my invention consists in various constructions and combinations of parts, which will be more particularly de-v scribed' in the specification and pointed out in the claims.

In the accompanying drawings, forming a 406,610 and 406,611.

Referring to said drawings, Figure 1 is side elevation of the delivery end of the ma- I' Fig. v2 is Fig. 3 is a plan. Fig. 4 is a detail vertical section of the oscili Fig. 5 is a detail;y Fig.:y

latin g and sliding frames. horizontal section of the sliding frame. (i is a detail vertical section of the guide.

A is the bed-plate or frame of the machine, i

in which are supported the pulleys B, around which passes the endless grooved belt C by: which the cigarette-rod D is fed through the guide E, which forms also a support for the g cigarette-rod.

Supported upon arms F, extending from the bed-plate A, is the shaft G, by which the cutting mechanism is actuated, and which is operated by connections with any suitable source 0f power. Arms II, extending from the end of the bed-plate, support the table I, upon which the severed cigarettes are delivered from the guide E through a chute, (not shown,) as is usual in this class of machines.

Referring now to the mechanism in which my invention is embodied, 1 2 are short shafts extending from and supported in thecnd of Be it known that I, DANIEL J. CAMPBELL, i

held vthereon by'means of removable collars 6, are two split collars 7, these collars being free to oscillate upon the sleeve. The vcutter K is secured-to the short shaft S, which carries a pulley 9, rotated by a driving-belt 10, connected to any suitable source of power. This short shaft 8 is journaled inthe cutterframe, which is preferably made-in two parts 1l 12, connected by slot and set-.screw connections 13, as shown in Figs. 3 and 4, whereby the cutter-blade maybe adjusted at an angle tothe cutting-die, as hereinafter described.

The lower section 12 of the cutter-frame is provided with the collars 7, previously referred to, by which the cutter-frame and cutter are supported upon the sleeve 3 and f ree to oscillate thereon.

Secured to the cutter-frame above its axis of oscillation and preferably to one 'of the collars '7, asshown, is the arm 14, extending lfrom a bar 15, which is operated in one direction by means of a spring 16, secured to the lower end o f the bar and to one of the table supports H. At its upper end the bar 15 is provided with a small plate 17, adjustably and nuts 19, as shown in Figs. 2 and 3. Upon the sliding frame 5 is carried also the standard 20, on which is supportedthe guide E, previouslyreferred to. This guideE consists, preferably, of lthe two dies 21 22 upon opposite sides 0f the plane of movement of the cutter, the die 21 being preferably provided, as shown, with a flaring opening serving as a centering-guide to the cigarette-rod on entering the die. A steel bushing 23 is adjustably secured in the die 21 and serves as a wearing-face for the cutter K.

The cutter K is preferably mounted so that its blade forms a slight angle with the wearing-face of the die, as shown in Figs. 3 and 6, a shearing cut thus being produced, which gives a smooth cut edge to the wrappers. The

cutter also by angular contact with the steel wearingsface is kept properly sharpened, being formed with a thin blade, preferably beveled on the side opposite the die. By the adjustment of the bushing and cutter, as previously described, the pressure between the blade and wearing-face and the angle of the blade may be varied as desired. By the use of a thin cutter-blade of large radius I am able also to obtain the requisite yielding` pressure between the die and blade without the use of springs, which have heretofore been employed for this purpose.

For operating the parts thus far described, so as to impart to the cutter K a movement transverse to the cigarette-rod and at the same time to move the cutter and guide longitudinally of and at the same speed as the rod, I provide the following mechanism: The shaft G, by means of beveled gears 24.-, operates a short shaft 25, journaled in a standard 2G upon the bed-plate A, this shaft 25 having an eccentric connection with a collar 27, carryin g pitman 2S, which is pivotally connected at its outer end to the carriage 5. The shaft if is provided also with a cam 29, carried by a sleeve 30, ad j ustablysecured upon the shaft by a set-screw 31, as shown in Figs. 1 and 3. rl`his cam engages the plate 17 at each rotation of the shaft G, thereby rocking bar 15 against the tension of spring 1G. i

The operation of the device is as follows: As` the cigarette-rod is fed by the endless band C through the guide E to the length required for a cigarette, cam 29 engages the plate 17 and rocks the bar 15 against the tension of spring 16, thus oscillating the cuttersupport and critter upon the sleeve 3 and carrying the rotating cutter K into contact with and through the cigarette-rod. As the cut ter engages the cigarettea'od the carriage 5 is operated by eccentric-collar 27 and pitman 2S to carry the cutter and guide forward with the cigarette-rod and at the same rate of speed, all buckling of the cigarette in cutting thereby being avoided. The cigarette having been severed, the cutter-frame is oscillated by the spring 1G and bar 15 to retract the cutter K from the guide, and the carriage 5 is operated by the eccentric to return the cutter and guide to their normal position longitudinally of the cigarette-rod.

It is evident that the mechanism embodying my invention may be varied and that the invention is not to be limited to the specific devies shown nor to the special form of machine to which the cutter mechanism is appivotally mounted and sliding cutter-frame,

of the cam 29 for oscillating said frame in one direction and the spring 16 for returning the frame, and positive driving means for reciprocating the frame in a straight line at right angles tothe plane of it-s oscillation, substantially as described.

2. The combination with the cutter and pivotally-mounted cutter frame, of bar 1.5 connected with said frame, adjustable plate 17 carried by said bar, a cam 29 engaging said adjustable plate, and spring 1G for returning the bar and frame, substantially as described.

The combination with the guide E having the die 23, of the disk cutter K rotating at an angle to and in contact with the face of said die, substantially as described. j

4. The combination with the guide E having the die 23, of the disk cutter K rotating at an angle to and in contact with the face of said die, and means for adjusting the angle at which the cutter engages the die, substantially as described.

5. The combination with the guide E hav ing the die 23, of the disk cutter K rotating in contact with the face of said die, and a cutter-supporting frame adjustable in the arc of a circle at right angles to the plane of rotation of the cutter whereby the angle at which the cutter-blade engages the die may be adjusted, substantially as described.

G. The combination with the sliding guide E having die 23, of the rotary disk cutter K, its shaft 8 and driving-pulley 9, and an oscillating and sliding cutter-frame adjustable in the arc of a circle at right angles to the plane of rotation of the cutter, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

DANIEL .I CAMPBELL.
