CUTTING MECHANISM FOR FORMING PROJECTIONS ON MOUTHPIECE MATERIAL.

SPECIFIGATION forming part of Letters Patent No. 716,535, dated December 23, 1902.

Application filed May 14, 1902. Serial No. 107,332. (No model.)

To (0Z6 whom it may concern:

Be it known that I, KARL HARNISOH, a citizen of the Swiss Republic, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in Cutting Mechanism for Forming Projections in Mouthpiece Material, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The invention relates to certain improvements in devices for forming retaining projections on mouthpiece material.

The mouthpieces of certain kinds of cigarettes have been heretofore provided with a series of tongues which project inwardly from the mouthpiece, said tongues forming a retaining-wall having a central orifice which prevents the tobacco in the cigarette from passing into the mouthpiece, but permits the smoke to be drawn therethrough. These retaining projections have been heretofore formed by means of pivoted cutters, which have been of such a shape that the projections produced thereby are generally rectangular in outline. The cutters referred to operate upon a strip of mouthpiece material, which is fed to them and which is afterward cut up into blanks. \Vhen, however, a blank which is provided with these rectangular projections is rolled up or coiled into a mouthpiece, the projections necessarily overlap. The result is that they do not fall readily into position and do not therefore form a perfect retaining-wall. Furthermore, it is necessary in the practical manufacture of cigarettes that the projections referred to before the blank are rolled up intomouthpieces be given a bend which is preferably greater than a right angle, so that the projections underlie the edge of the material. In the con structions heretofore employed the cutters have been depended upon to bend down the tongues, and it has been found difficult to so arrange the construction that the cutters both out the material and effect the bending.

This invention has for one of its objects to produce an improved cutting mechanism for forming the projections on mouthpiece material which operates to give apointed form to said projections,so that they come readily into position when the mouthpiece is rolled up.

Afurther object of the invention is to produce an improved mechanism for bending the projections on mouthpiece material at an angle to said material after the projections have been formed and prior to the time when the mouthpiece is rolled up.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter described and then more fully pointed out in the claims hereunto appended.

Referring to the drawings which form a part of this specification, and in which like characters of reference indicate the same parts, Figure 1 is a plan view of the improvedcuttingandbendingmechanism. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a side view. Figs. 4 and 5 are top and side views, respectively, of the strip of mouthpiece material; and Figs. 6 to 14, inclusive,

illustrate'a concrete embodiment of the invention is designed to operate upon a strip of mouthpiece material, which is thereafter cut up into blanks which are coiled into mouthpieces.

In the drawings, 140 indicates a support or table over which the mouthpiece material may be fed in any suitable manner. In an organized machine the mouthpiece material may be given its movement by a pair of intermittently-operating milled feeding-rolls, which are indicated at 47, the operating devices for which have been omitted in the interest of clearness of illustration. The support will preferably be provided with suitable guiding devices, which operate to properly direct the strip in its movement over the ta ble. As shown, these devices include a guide 141, which is preferably made adjustable by any desired means. As shown, the guide is slotted and is secured to the table 140 by means of screws 142. A presser-block 143 is also provided, said block being, as shown, se-

cured by a screw 144 to a block 145, said block being supported on a bracket 146,which is connected in any suitable manner to the bed-plate of the machine. This block 145 is preferably provided with a slot 147, through which the paper runs, the inner side of the slot acting as a guide for the paper.

The cutting devices employed may be varied in construction. In the construction shown they embody a movable cutter and a stationary cutter. The movable cutter comprises a block 148, which moves in ways in the block 145. The operating-face of this block, which is marked 149, is provided with a series of angular cutting projections 150. These projections are preferably formed by V-shaped grooves 151, and in the preferred form of construction these grooves will be long enough to form projections of the same length in the body of the block. As shown, the projections formed by the grooves extend the entire length of the block, although it'is obvious they might be shorter, if desired. The block 145 is provided with grooves 152, which are engaged by the projections 150, so that the cutter-block 148 is accurately guided in its movement. Preferably, furthermore, the operating-face of the block 145 will be given a sharp bevel, as shown, so that the ridges and edges of the cutting projections form points. These points enter the paper in advance of the remainder of the cutting edges of the projection, and these in co6perating with the cutter, to be hereinafter described, produce a shearing cut. The coopcrating cutter, which is in the present construction shown as stationary, consists of a block 153, said block being preferably seated in a recess in the bracket 146 and being secured thereto in-any desired manner. This block is grooved, so as to produce cut-ting pro- -jections 154, which correspond in shape with the cutting projections on the block 148. These projections are, however, arranged so that they register with the grooves in the block 148. The operating-face of the block 153 preferably lies in the same plane with the face of the table 140. The projections, the face of which form the cutters on the block 153, preferably extend some distance from the face, but decrease in height, so that the clearance is given for the pieces of paper which are cut out by the cutter.

In the operation of the construction so far described as the cutter-block is moved downward by the mechanism to be hereinafter described its pointed projections first pierce the paper and engage the bottoms of the grooves between the cutting projections 154 on the block 153. The further downward movement of the block 148 causes the pieces of paper on the edge of the mouthpiece material to be severed with a shearing cut, and the pieces thus severed drop from the cutter, this operation being facilitated by the decrease in height of the projections on the block 153.

The means for operating the movable cutter may be of any suitable description. As shown, there is provided a bracket 155, which is secured by screws 156 or in any'other suitable manner to the bracket 146. This bracket is provided with dovetailed ways in which moves a slide 157. This slide has extending from it a pin 158, which engages a recess in the cutter-block 148. In the preferred construction the block 148 is held yieldingly against its guiding-block 145, and, as shown, this is effected by means of a spring 159, which surrounds the pin 158. The reciprocating movements of the slide may be produced in any desired manner. In the construction shown they are effected by means of a bent lever 160, said lever being pivoted to the, bedplate of the machine at 161 and being provided with a cam-roll 162, which runs on the surface of the cam 163, mounted on a shaft of the machine. A spring 164 is provided to produce the movement of the lever in opposition to the cam. This lever 160 is connected to the slide 157 by means of a connecting-rod 165.

After the cutters have operated to produce the pointed projections on the edge of the paper the paper is moved forward and is operated upon by a bending mechanism, which is independent of the cutter. This bending mechanism may be widely varied in construction. As shown, it embodies a bending-block 166, this block being preferably beveled, as shown. The block cot'iperates with an abutment which maybe formed by the edge of the support 140, and in the preferred construction the edge of the abutment will be undercut, as shown at 167. The bendingblock may be mounted and operated in any desired manner. Preferably, however, it will be yieldingly mounted, and in the construction shown it is carried on a spring-plate 168, said plate being secured, by means of a setscrew or in any other desired manner,to a hub 169. This hub 169 is adjustably mounted, by means of a set-screw 170 or in any other suitable manner,-on an arm which is secured to the slide 157, the connection being effected by means of a screw or in any other desired manner. As the slide 157 reciprocates, therefore, the bending-block will be given reciprocating movements and striking the projections formed by the cutters on the edge of the paper will bend them under the edge of the abutment.

While the bending device so far described may be sufficient to bend down the projections, it is preferable to give the projections a still further bend, so as to insure that they do not fly up when the mouthpiece material is rolled, and an auxiliary bending device is employed for this purpose. This auxiliary bending device may be of any suitable character. In the construction shown it consists of a pair of overlying plates 171172, which are arranged to form a space between them. The plate 171 is beveled on its edge slightly, as indicated at 173, to permit the strip of paper to easily enter between the plates, and

several parts.

the plate 172 is provided with an angular edge 17 4, across which the pointed projections travel. This edge lies at an angle to the line of movement of the strip, which is preferably an obtuse angle. The projections thus ride easily across the edge of the plate 172 without catching on it, and as the strip passes between the plates the projections are bent still farther under the edge of the strip, as is shown in Figs. 4 and 5.

While the mechanism which has been described is particularly adapted for operating upon a strip of mouthpiece material, it is obvious that the invention could be applied to machines in which mouthpiece-blanks are separately fed to the cutting devices. It is also obvious that many changes could be made in the relations and operation of the The invention is not, therefore, to be limited to the specific construction which has been hereinbefore described.
