PATTERN.

Aft-E(.IIEICATION forming part of Letters Patent No. 373,451, dated November 22, 1887.

Application filed March 12, 1887. Serial No. 230,636.

To all whom, may concern/.-

Beit known that I, GEORGE E. FEosT, of Sheboygan, county of Sheboygan, XVisconsin, have invented certain new and useful Im- 5 provements in Patterns, of which the following is a specification.

My invention relates to that class of patterns which are used by laying them upon the object and cutting around the pattern; and it Io consists in the particularshereinafter set forth. Heretofore patterns for this purpose have been made of pasteboard and bound around the edge with brass to prevent their being bent or broken, or cut by the knife when in use.

These patterns are expensive, and the brass edge tends to dull the knife when in use, besides which, as the edge is bound with brass, the central part of the patterns will not lie smoothly and evenly upon the material to be 2o cut, but there will always be more or less of a space between the pattern and the material, which will allow the material to pucker and wrinkle, and thus get ont of shape. To avoid these objections, I use material formed of two or more veneers or laminze of wood, with the grain crossing and glued together, which I have found by experiment to be particularly suitable for this purpose when the patterns are constructed as I shall hereinafter explain.

In the drawings I have shown patterns for parts of a shoe, Figures 1, 2, and 3 beingplan views of various parts, and Fig. 4 being van edge view showing the beveled edge at a a.

I make my patterns by first cutting them out of flat pieces of three-ply veneer, thus giving them the desired outline. The edges must be smooth, so as not to catch the knife when in use, and I nd it preferable to give them the rounded or beveled form shown in Fig. 4,

4o which I find will not catch the knife. Besides,

the nature of the material is such that instead of blunting and dulling the knifein use,itacts to whet and keep the knife-blade sharp; and this feature may be still further availed of by oiling the edges of the pattern, as indicated by the shaded lines in the drawings, which will (No model.)

cause it to not only whet the blade better, but also to polish and presentV a smoother surface to the blade. Again, the pattern being flat, without any raised edge, its whole surface will 5o lie evenly and smoothly upon t-he material to be cut, and allow no room for it to wrinkle or pucker or slip ont of shape, as is the ease in using the brass-bound patterns; and while my improved pattern is light and very durable, it is very much cheaperto make than the old style, is easily packed without fear of injury, and will be found by the trade to be a very desirable article.

Laminte of wood glued together with the 5o grain crossing are peculiarly well adapted as material for cutting out patterns, as they lie perfectly ilat and never twist. The edges ot' the exterior laminte may be beveled, and they will still support and be supported by the o5 central lamina on all sides ofthe pattern. The edges are uniformly hard and smooth all round, and the pattern is lnot vliable to split away or break off at sharp corners. The pat-- terns cost less than brass-bound patterns, and 7o the beveled edges clear the knife, so that its edge is not bluntedand the pattern is notI cut.

A brass-bound pattern cannot be given beveled edges, except at very great cost.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the 'United States, is-

As a new article of manufacture, a cuttingout pattern formed of three laniinze of wood glued together with the grain crossing, the 8o edges of the said lamin being smoothly polished for the knife to bear against, and the outer laminze beveled to clear the knife edge and still support the center lamina, thus producing a hard grainless edge all round the pattern, substantially as and for the purpose set forth.
