To all whom it may concern:

Be it known that I, BENZION KARFIOL, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Paper Cutting and Emboss- Figure 1, is an elevation of my device viewed from the side. Fig. 2, is a top view of the same omitting the revolving brush g Fig. 3, is a sectional view taken on the lines 22. Fig. 4, is a sectional view of the guide roller.

A, is a frame provided with ways, a, a a and carrying the shafts journaled therein, B, O. The shaft, B, is provided with the pulley,

' b, at one end outside of the frame, and at the other end with a pinion, 17 also outside of the frame. The shaft, 0, carries the gear wheel, 0, which engages the pinion, b

movement of the screws, the. shaft carrying the revolving brush will be moved.

A brace D is secured between the frames A A, preferably secured thereto by bolts, as d and 01 shown on one side in Fig. 1, but not shown on the opposite side. tional view Fig; 3, the holes for these bolts This brace D is provided with an aperture d which forms a way throughout its length, adapted to receive and carry the bracket d". Shown in Fig; 3. The bracket d is provided at one end with the journal bearing d adapted to receive the shaft 0 of the die. It rests on the brace D and slides in the way (1. The bracket d is secured to thebrace D by the screw d nut d and thus may be adjusted to any position on the brace D. It will be understood that two of these brackets support the die. They are shown in Fig. 2 at d and (i As stated the shaft 0 is journaled in the frame A A. The cylindrical die g is preferably keyed to this shaft, and the journal bearings 01 and d of the brackets 01 and 01 are run upon the shaft 0, and adjusted as close as practical to the ends of the die thus lending support to the shaft on which the die is keyed, when pressure is exerted against the die.

The stays E and E are provided with slot throughout their length forming ways. I have shown a sectional view thereofin Fig. 3. The brackets e and e are secured to the stay E by the screw e and nut 6 and may be adjusted to any position on the stay E, by movin g the samein the ways thereof. The brack ets e and e are provided with the journal In the secbearings e and c and the ways e and e The shaft Z is journaled in thejournal bearings e and 6, which are adjusted as near as practical to the roller Z. The roller 6 is journaled in the movable bear-ings e and e which move in the ways a and e. Such movement is controlled .by the screws, 6 e, to cause the roller, e, to bear u pontheroller Z.

6 is a metal bar preferably square, or made so as to present a cutting or planing edge to It moves in the ways e7 e and its movement is controlled by the pressure screws e a which cause the same to bear on the roller Z.

The stays E and E, and their attachments,

are identical with the exception that in operatin g the apparatus, as will be hereinafter described, the compression roller, e, and the cutting edge, a are omitted when the brackets are used to carry the embossing roller.

The rollers w and are suitably mounted on, and secured to their respective axles, 0c and .2, which are journaled in the brackets e e. The roller 1 is secured to the shaft, 0, and revolves therewith. The roller y is the die roller, the roller .2 the cutting roller and the roller :0 the matrix or embossing roller.

The die roller is of metal, usually engraved according to a design on its periphery, the die being made to present in certain parts cutting surfaces to cut the paper or similar material presented to it, and at other parts to present concave or convex surfaces to emboss or indent the paper, all according to a predetermined design intended to be impressed upon the paper.

The cutting surfaces of the die, are a degree elevated above the embossing portions. This is illustrated in the drawings Fig. 4, in which a section of the die is shown, the parts indicated ast'-i, being the cutting surfaces, and those indicated as j--j are embossing surfaces.

The roller .2 is known as the cutting roller, for the reason that it cooperates with the cutting edges of the die to cut the paper. It has a smooth surface, or periphery, and when brought into contact with the die roller, en gages the cutting edges which as heretofore recited, are a degree elevated above the embossing portion of the die. The paper is passed between these rollers and the cutting action is performed.

Heretofore it has been customary to employ as the material of which the cutting roller was made, a soft metal such as lead, or material similar to leather. I may employ in this press, rollers made of any suitable material, but I prefer to use for such rollers, as best adapted for the purpose, the material described and claimed by me in my application for United States Letters Patent, dated the 8th day of January, 1894, filed February 12, 1894, Serial No. 499,846, in which I describe a chemically treated and compressed paper, or vegetable fiber, for use in this connection.

I have shown in my drawings, and described, a roller, e, and a cutting edge, a intended to bear on the roller ,2 for the purpose of smoothing the surface thereof, as the same is afiected by the cutting edges of the die. hen soft metal, such as lead, is employed as the cutting bed, it is necessary constantly during the operation of the machine, to plane oif, and roll down the surface, in order that the same maybe kept as smooth as possible. The hard metal bar presents to the rollerachisel edge, and is pressed against the same by the screws, 6 e", operating to plane or scrape the surface of the roller as it revolves, but it is not always necessary however to plane or scrape the cutting roller. Often it is sufficient to cause the roller e which is of some hard metal, to bear upon the cutting roller by means of the screws, c, 8 while the cutting roller is revolving. This operates to smooth the surface of the cutting roller by pressure. WVhether the cutting edge or roller or both are employed is dependent upon the material of which the cutting roller is made and must be determined by a proper adjustm ent of the parts accordingto the work to be done. I have found that where a roller made of chemically treated and compressed paper, or vegetable fiber is used as the cutting bed, it is unnecessary to use the cutting or planing edge a or the compression roller 6. These may, therefore, be omitted in this case.

The roller 00 is the matrix or embossing roller. That which has been said herein regarding the material employed in the manufacture of the cutting roller is also true of this roller. Lead and other soft metals have been used, also leather and kindred materials, but I prefer to use as best adapted for the purpose the material described in my said application. The matrix is made by bringing the die roller and a roller of suitable material into contact under pressure, and revolving the same repeatedly, until the elevations and depressions of the die are fullyimpressed into the surface of the matrix roller.

It has been my observation and experience with apparatus heretofore constructed for the purpose of cutting and embossing paper, that they were frequently inoperative for the reason that it was impossible in their construction to adjust the parts to a perfect center, or to bring the die in such relation to the cutting and embossing rollers as to be successfully operative. One of the causes of this difliculty of adjustment in the apparatus referred to, is the fact that the pressure directed against the die roller, or the cutting or embossing rollers, as the case may be, in the operation,

is calculated to bend the shaft or axle upon which they are mounted, thus causing the operation of the machine to be impeded, and the die and its cutting bed, or the die and its matrix to be thrown out of uniform engagement. This is the case for the reason that in ma chines constructed for the purpose heretofore, the rollers have been mounted on shafts or axles of a length sufficient to accommodate a die and its rollers of any length. With this construction the shorter the die and its rollers, the more liable were the shafts and axles to bend, as the pressure thereon was brought nearer the center thereof. To obviate these difficulties I have constructed a machine in which the pressure of the cutting roller and matrix roller is directed against the die in one plane running through the center of the three rollers. Then I have provided brackets with journal bearings to carry and sustain the shaft on which the die roller is'keyed, said brackets being adjustable so that they may sustain the shaft on both sides of the die roller and close to the same, and act as a brace to the shaft to prevent the same from bending, on the principle that the shorter the shaft the greater its strength or power of resistance.

In like manner I have provided adjustable brackets having journal bearings, to carry the axles of the cutting and matrix rollers, intended to be adjusted to sustain the axle of the rollers, on both sides thereof and close to the rollers. It will be observed that with this arrangement, whatever may be the Width of the die and other rollers, the brackets may be adjusted to sustain the'shaft or axles close to the rollers, and avoid the danger of the shaft or axies bending, as heretofore recited.

In the drawings, Fig. 1, I have shown a revolving brush 9 which is omitted in Fig. 2 j ournaled in the movable bearings, g, and actuated by the belt, 9 The position of this brush is determined by the movement of the screws,f and f and it is intended to bear on the die rollers and paperin the operation ofthe machine, and in its revolution to brush away the portions of the paper which have been cut out of the paper band as it passes between the die and the cutting roller, in order that such particles of the paper may not interfere with the embossing operation byfilling up the matrix or otherwise.

By the arrangement of adjusting screws, it will be observed that I can bring a high degree of pressure to bear on the cutting and matrix rollers, in directing them against the die, and that I can regulate this pressure to either end of the rollers, so that should there be any irregularity in the roller, I can compensate for the same by operating the screws.

I have so constructed the frame of the device that the die roller is in the center thereof, and I have formed three ways, or guides, in which the stays carrying the rollers and brush may move. I may, therefore, with this arrangement, shift the position of the rollers and brush at will, that is to say, I may change the places of the matrix roller and brush, or cutting roller and brush, or matrix or cutting rollers, as I may find the efficient operation of the machine may require.

The operation of the device is that of passing a band of paper, as H wound on a spool h, under the guide, if, thence between the die rolleryand cutting roller 2, when these operate to cut the paper; thence between the brush, g, and die roller, the brush operating to remove the particles of paper out out as stated; thence between the matrix roller 00 and die roller 1 to perform the embossing of the paper; thence to the spool h Power is conveyed from the pulley, I), through the train to the die roller, and the cutting and embossing rollers are caused to bear on the die roller and revolve therewith. The brush, 9 receives its motive power from the belt,

g but it may, of course, be operated otherwise.

What I claim is 1. In a paper cutting and embossing machine, the combination with a cylindricaldie suitably journaled, and cutting and embossing rollers, of brackets provided with journal bearings, to carry the shafts upon which the rollers are mounted said brackets being supported by stays having ways in which the brackets are adjustable, according to the length of the axes of the rollers, and said stays working in ways at right angles to the axis of the die and rollers and means to compress said rollers against said die and to adjust said pressure substantially as described.
