IMPROVEMENT lN METHODS OF PREPARING FABRICS TO BE CUT INTO ORNAMENTAL SHAPES.

Specification forming part of Letters Patent No. 179,575, dated July 4, 1876; application filed February 26, 1876.

.desired to produce considerable numbers of elaborate shapes for decorative and other purposes at short notice, or in too small quantities tojustify the execution of dies. Our invention applies to such cases, and allows the production of great numbers with a high degree of perfection, and at a very moderate cost.

We provide thin boards of wood, (one penciled or otherwise marked with the desired pattern, suitable to guide the operator in cutting with a jig-saw,) and we strongly compress a number of layers of paper or cloth between the two boards, and secure the edges firmly together in the compressed position by strips of muslin glued thereoinand uniting the whole into a single compact slab. .lhus prepared, we find that the layers may be sawed through by ajig-saw in good condition, and that, after treating the whole exactly as if it were a sin gle thickness of wood, the parts may be separated, and twenty shapes, more or less, of paperwill befound to have been thereby produced, exact fac-similes of each other, and accurate reproductions of the pattern which was penciled on the upper piece of wood.

WVe prefer to compress about three-quarters of an inch thickness of paper between two boards, each of a half-inch in thickness. In treating woven goods the best work will be performed by making the pile of fabric still thinner-say, about half an inch of cloth between two half-inch boards. Oare,should be taken to execute the minute figures near the center of the pattern before the edges are much out, so as to release, or partially release, the material from pressure.

The accompanying drawings form a part of this specification. v

Figure 1 represents a quantity of material partly shaped according to our invention. Fig. 2 is across-section through the mass before being shaped.

Similar letters denote like parts in both figures.

A is the pile of paper or cloth. B is the upper board. 0 is the lower board, and D is the binding of muslin, which is glued upon the edges, while in a compressed condition, to firmly secure the whole together.

We have found no particular difficulty attending the compressing operation, and do not esteem it necessary to describe it by drawings. Any simple screw or lever press may be used having flat surfaces of a proper size, with a clear space around, to allow the application of the muslin D.

We claim as our invention-'- The within-described process .of preparing cloth or paper for sawing into ornai'ncntal shapes, consisting of compressing a number of laminae, A, between boards .13 G, and gluing or cementing the edges of the whole with a strong fabric, 1), substantially as herein specified In testimony whereof we have hereunto set our hands this 24th day of February, 1876, in the presence of two subscribing witnesses.
