- specification.

My invention relates to machines for cmbossing paper, wood, and other similar materials; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings, and to the claims to be hereinafter given.

Figure 1 of the drawings is a side elevation of so much of a machine as is necessary to illustrate my invention. Fig. 2 is a central vertical section of the same, the cutting-plane being parallel to the side of the machine.l Fig. 3 is an elevation of the side of the machine opposite to that shown in Fig. 1. Fig. 4 is a front elevation of the upper portion of the same with the feed apron and roll removed, and Fig. 5 is a section ofa portion of the feedapron. Y

In the drawings, A A are the side frames of the machine, connected together by the tierods B B, and having bolted to their upper edges the stands A A', slotted to receive the boXes O C, in which is mounted the engraved embossing or die roll D. The upper ends of the stands AA are tied together by the cross- 'head E, provided with the long slot a, in which is fitted the wheel-nut F, which works upon the screw b, firmly secured in the tie-bar G, connecting the boxes C C in such a manner that by turning the wheel F the boxes C C and the embossing-roll D will be moved upward or downward, according to the direction said Wheel is turned. The lower ends of the stands A A' are firmly bolted to the bed-girt I-I, provided upon` its upper side with a rounded rib, c, the apex of which is directly beneath the axis of the embossing-roll D, as shown.

I is the feed-apron, mounted upon the rolls I and I2, and composed of a layer or thickness of leather, d, and a layer or, thickness of rubber, c, the two materials being firmly secured together over their entire contact-surfaces by means of rubbercement or other suitable adhesive material, so that the rubber, while it may yield to the pressure of the embossingroll, cannot stretch longitudinally or laterally. 'y

This belt or apron passes between the embossing-roll D and t-he bed-girt I:I, and upon its surface rests the sheet or web of paper or other material to be embossed as it is being fed through the machine.

The shaft of the embossing dierol1 D has mounted upon one end thereof the spur gearwheel J, with the teeth of which the teeth of the pinion J engage to impart to said roll a rotary motion. The pinion J is mounted upon one end'of the shaft K, mounted in bearings in the arms L, secured to or formed in one piece with the boxes C C, and carrying at its other end the driving-pulley M. The shaft of the die-rollD also has mounted thereon the gear-wheel N, which, acting through suitable intermediate gears, N and N2, and the gear N3, secured upon the shaft of the roll 12, imparts to said roll IZ a rotary motion, and causes the apron I to be moved around said rollat a speed corresponding to the speed of the periphery of the die-roll D.

O is an endless metallic apron mounted upon the roll O' and another (not shown) at any suitable distance from O', said apron being moved in unison with the apron'I by means of the gearwheel O2, mounted upon the roll O,'and the intermediate gear-wheel meshing into said gear-wheel O'l and the gear N3, as shown. The apron O is heated by means of a coil of pipe, P, interposed beneath the upg per portion of said apron, into which steam is admitted through pipe P', connected with any suitable source of supply, and from which it is discharged at the opposite end of said coil.

It is designed to make the apron O of sufficient length and extend the coil of steam-pipe to sufficient distance to completely dry the moistened paper before rolling it up after being embossed.

R is a tie-girt connecting the main side frames of the machine with the stands for supporting the outer roll for supporting the apron O, which roll is not shown inv the drawings, but may be of any ordinary construction.

S is a shaft mounted in bearings in the main frames of the machine, and has mounted thereon the roll of paper, S",which is to be embossed. The paper to be embossed is moist- IOO ened, and the end of the Web is placed upon the apron I and passed beneath the die-roll D, and is thus subjected to a heavy preasure between the die-roll D and the apron I along a narrow line above the apex of the rounded rib c of the bedgirt H, the rubber outer surface of the apron I yielding to permit the projecting portions of the design on the die-roll to embed the paper in said rubber Without so stretching the apron, either longitudinally or transversely, as to wrinkle or Vtear the paper. The embossed paper passes from the apron I upon the heated metallic apron O, to be conveyed to a sufficient distance away to be thoroughly dried, when it is rolled up or otherwise disposed of to put it in suitable condition for the market.

Other materials-such as paper or paperpulp combined with cloth or wood-may be embossed successfully upon this machine.

l/Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine for embossing paper,wood, or other material, the combination of a revolving die-roll, a fixed bed-girt beneath said dierolland havingarounded upwardlyprojecting rib extending longitudinally thereof and opposed to and parallel with the under surface of said roll, and a flexible and yielding feed-apron vsupported by said rounded rib, and. mechanism, substantially as described, for moving the periphery of said dieroll and the upper surface of said apron in unison, as set forth.

2. In a machine for embossing paper,wood,' or other material, the combination of a revolving die-roll, a fixed bed-'girt beneath said dieroll and having a rounded upwardly-projecting rib extending longitudinally thereof and opposed to and parallelvvith the under surface of said roll, an endless feed-apron supported by said rounded rib, and mechanism, substantially as described, for moving the periphery of said die^rol1 and the upper surface of said apron in unison, as set forth.

In testimony Whereofl have signed my name to this specification, in the presence of two subscribing Witnesses, on this 22d day of June, A. D. 1887.
