BOOT-TOP AND MANUFACTURE OF THE SAME.

SPECIFICATION forming part of Letters Patent No. 369,240, dated August 30, 1887.

Application filed June 215, 1887. Serial No. 242,309.

To all whom it may concern:

Be it known that I, J OHN THOMAS GRAY, of Grayfitutsman county, Dakota, have invented certain new and useful Improvementsin B0ot- Tops and in the Method of Forming the Same, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, forming part thereof, in which Figure l is a side elevation of the front section of a boot-top prior to forming the fold. Fig. 2 is asimilar view showing the fold formed, and also showing the back section of the leg. Fig. 3 is a sectional view on the line or m of Fig. 2, and Fig. is a side elevation of the two sections secured together.

The object of the invention is to lessen the labor and therefore the cost of making boots; and the invention consists,principally, in form ing the front section with a fold or swell adjacent to the lower ends of its edges at the rear of the vamp, substantially-as hereinafter described and claimed.

A represents the frontof the boot leg,which is crimped over double,and having the edges of its leg portion a formed straight from the top to the point cf, which is somewhat below the top of the instep and thence inclined rearward, as at a, on a straight line, as shown'in Fig. 1. The inclined portions of are now brought into line with the straight edges of the part a, and doubled over to form the folds or swells G, as shown in Fig. 2, which folds are kept in shape by pressing or hammering, or in other suitable manner. The front is now ready for the crimped back B,which is formed with approximately straight edges.

As the swell or fold C has been previously formed, I have only straight seams to stitch, and therefore merely form a lap-joint and stitch the two parts of the leg together, and both hands wili be free to manage the work and the machine.

If desired, the front and back may be cc (No model.)

mented together instead of stitched, or both means may be used in some instances.

The folds or swells 0, formed as described, provide the vamp with the desired fullness, allowing it to be very quickly fitted to the concave waist of a last at each side next to the sole of the boot, and straining of the leather is entirely avoided. By this method a great deal of time will be saved, as only previouslyformed straight edges have to be united, and no turning of the completed boot-leg is required. By actual experiment I find that I can by my method save one honrs time over the ordinary method of making a single pair of heavy boot-tops. After the front and back have been crimped it only requires about twenty minutes to form the fold G and stitch the sections together.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is-

1. In the method of forming boot-top fronts, the steps consisting in cutting the front with approximately straight rear edges to points at or near the ankle, and with the rear anguiar extensions therefrom below said points, and finally bringing the angular extensions in line with the straight edges above them and forming the folds, substantially as set forth.

2. A boot-leg front formed with straight rear edges, and having the fold 0 extending from the point a to its lower edge, substantially as set forth.

3. The combination, with the criinped front A, having straight rear edges, and the. folds (1, extending from the point a to its lower edge, of the back B, lapped and stitched to the previously-formed straight rear edges of the front section, substantially as set forth.
