DISH-CUTTING MACHINE.

Specification of Letters Patent.

Patented Nov. 19, 1912.

Application fllejd October 20, 1911. Serial No. 655,777.

To all whom it may concern: 4

Be it known that I, PAUL RAYMOND SIM- MONS, a citizen of the United States, and a resident ofMarion, in the county of Grant and State of Indiana, have invented anew and Improved Dish-Cuttin Machine, of which the following is a 1111, clear, and exact description.

My invention relates to a dish-cutting maconfiguration of knives, and by regulating.

the pressure of the other roller against the lmife-carrying roller, so as to cut a roll of paper passing between the rollers into the configuration outlined by the knives.

With the above and other objects in view,

as will more fully hereinafter appear, the

present invention consists in certain novel detalls of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which t Figure 1 is a front elevation of a'pre-' ferred embodiment of my machine, certain parts being broken away to disclose details;

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1; Fig. 3 is a perspective view showing one of the knifeblocks detached from the roller, and Fig. 4 is a part of a roll of paper showing the patterns cut therein.

Spaced apart upon a base 1 and fastenedv to said base by bolts 5, is a pair of uprights 6 of any suitable construction, each of which uprights has a bearing 7 therein, carrying a shaft 8; rigidly upon said shaft, interme-.

diate the uprights 6, isa knife-carrying drum 9. One end of the shaft 8 terminates into outside of the adjacent u right in a power wheel 10, the opposite en of said shaft out side of its ad acent end having rigidly mounted thereon a gear wheel 11. This gear wheel is in permanent mesh with a similarly constructed gear Wheel 12 rigidly mounted upon one end of a shaft 13, which shaft extends above and arallel to theshaft 8, and rigidly mounted upon the shaft 13 and coactlng with the drum 9 is a roller 14;

ticularly in Fig. 2, and are capable of vertical movement in slideways 16, and enlarged portions 17 of the uprights 6, and above each of the bearings 7. The journal boxes 15 are supported bycoil springs 18 disposed in pockets 19 above the bearings 7, and the roller 14 is adjustably pressed into engagement with the drum 9 by means of a bearing bolt 20 mounted in the top of each upright By this construction it is seen that the tension between the rollers 14 and 9 may be regulated.

As shown more particularly in Fig. 2, the roller 9 has a series of pockets 21 spaced about its periphery, each longitudinal side of each of said pockets being in a plane to form pyramidal pockets passing through the axis of rotation of the drum; Adapted to be disposedin the several pockets 21, are knife blocks 22, said knife blocks having positioned thereon, cutting knives 23, and extending through said blocks are apertures 24 by means of which the blocks may be knives 23 may be of any desired configuraments of circles, so that several of the knifea roll of paper 25 passing between the rollers into the shapes shown in Fig. 1. Further, several of the blocks may carry straight cutting knives 26, whereby cuts 27 may be made from the edge 28 of the roll of paper .to. theedge of a pat-tern 29. The edges of adjacent patterns are tangent to each other, whereby the greatest number of plates may be .cut from the minimum amount of paper.

In order to guide the rollof paper, a pair of fingers 30 are disposed on opposite sides of the roll, said fingers being rigidly mounted upon a rod 31 journaled at opposite ends removably fastened to the drum 9. These' The shaft 13 is loosely mounted in a pair of journal boxes 15, which journal boxes are square in cross section, as shown more par- 6, and bearing upon the journal boxes 15.

carrying blocks suitably arranged will cut in brackets 32, which brackets are mounted I means comprising a knife-carrying roller upon the front of the uprights 6.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

- 1. In a paper-cutting machine, a roller, a series of removable blocks carried by said roller, and rigid knives mounted on said blocks, said knives being independent of each other and arranged to cut a circular pattern in the paper, certain of said blocks carrying knives common to two circular patterns, whereby the knives common to two 4 circles may be carried by one block.

- 2. In a paper-dish-cutting machine, means for cutting a roll of paper into designs, said.

having a series of spaced-apart frusto-pyramidal. pockets dis osed about its periphery, a knife block isposed in and fitting each of said pockets, means for removably fastening said blocks in position, and a knife carried by each block, the knives of adjacent blocks coacting to cut a pattern.

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

PAUL RAYMOND SIMMONS,
