Definitions

• the object of my invention is to facilitate the labor of scalloping shoe-button laps or flies, and to avoid the necessity of making nailholes in the stock; and the invention consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.
• Figure 1 is a plan View of my new and improved button-fly clamp, showing the method of using the clamp; and Fig. 2 is a side elevation of the same.
• A represents the base of the device, which i may be the top of a table or bench.
• the main casting B which is formed with the overhanging arm or extension 0, through which the screw D works.
• the arm 0 is formed with the side projections, b, which have the plain orifices 0 made in them.
• the clamp-plate D which is curved, as shown in Fig. 1, and formed or provided with the pins cl, which enter the orifices c, and thus serve as guides to the up-anddown movement of theplate D in using the clamp.
• the stock to be scalloped and shaped into button laps or flies is first properly placed under the plate D, as shown at E.
• the pattern F is then placed upon the stock and the screw D turned by the handle D for bringing the clamp'plate D down snugly upon the pattern and stock, for holding the same while the stock is being cut and scalloped.
• the clamp is convenient and practical for its purpose 5 and in order to prevent' the pattern F from coming in contactgu with the casting B, so as to become worn and injured, I provide the casting B, at its forward corners, with the cushions c e, of leather,
• the plate D In a button-fly clamp, the plate D, swiveled to the operating-screw, and provided with pins d for guiding the plate, substantially as described.
