MERRILL A. TYLER, OF NEW DURHAM, NEW HAMPSHIRE, ASSIGNOR TO FRANKLIN W. OOBURN, OF SAME PLACE.
IMPROVEMENT IN WELT-TRIMMERS.
Specification forming part of Letters Patent No. 157,947, dated December 22, 1874 application filed October 14, 1874.
To all whom it may concern:
Be it known that I, MERRILL A. TYLER, of New Durham, in the county of Strafford and State of New Hampshire, have invented certain new and useful Improvements in VVelt- Trimmers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable dthefs skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
In said drawings, Figures 1 and 2 are opposite side elevations, and Fig. 3 a front end view, of an implement constructed in accordance with my invention. Fig. 4 is a transverse section taken on line x w of Fig. 1. Fig. 5 is a view of the stock and knife, with the guard removed. Fig. 6 is an inner side view of the guard.
My invention has reference to that class of devices employed by shoemakers for trimming or cutting out the welt or inner edge of the sole of a boot or shoe; and consists in the peculiar construction and arrangement of the several parts, as hereinafter more particularly referred to and claimed.
In the drawing, A denotes the stock, which is a block of metal secured by means of a tang to the handle B, in the ordinary manner. The lower edge of the stock is made of a curved shape, to rest on the sole while theimplement O is a curved segmental cuttingblade, which is disposed within a correspond.- ing segmental guiding-chamber, a, formed in the interior of the stock, as shown in Fig. 5. D is the guard, which has the shape as shown in Figs. 1 and 6, such guard having a lip, c, projecting at a right angle from its outer face, as shown in Figs. 2 and 3. This guard has on its inner face two projections or lugs, 01 01,
having a space between them corresponding with a segmental projection, 6, (formed on the inner face of the stock,) such lugs 01 61, when the guard is in place, abutting against the opposite sides of the projections e, and serving to maintain the guard in a fixed rigid position on the The guard is made to overlap and rest stock.
on the body of the knife, and by means of a screw, E, passing axially through the guard and into the stock, serves not only to clamp the knife in the desired position, but the guard firmly to the stock.
Thus it will be seen that while the guard is stationary, the knife, as it becomes worn, may be readily moved up, (being guided by its chamber,) and adjusted with relation to the guard, whose lip slightly projects over the point .of the knife, and thereby prevents the latter from coming in contact with the vamp or upper while the implement is in use.
It will also be seen that by forming the guard detachable, and so applied to the stock as to overlap the shank of the knife, such guard serves as a clamp to hold the knife when adjusted most effectively to the stock, and in due relation to the guard, while a single screw firmly secures both knife and guard to the stock without theintervention of a clamp-plate.
I do not claim, broadly, the combination of a lipped guard, and a knife or cutter applied to a stock to constitute a welt-trimmer; nor do I claim, broadly, a welt-trimmer havingits cutter and guard so made and applied to its stock as to be adjustable, as I am aware that such is not new; nor do I broadly claim a welt-trim mer,so made that the knife and guard may be detached from the stock, as 1 am also aware that such is old. 7
Having thus described my invention, what I claim is- In a welt trimmer, substantially as described, the stock A, provided with the segmental chamber a, to receive and guide the segmental knife 0, the guard D, formed and applied to the stock so as to lap upon the shank of the knife, and the screw E, arranged to clamp the parts together, as shown and described.
In testimony that I claim the foregoing as my own invention I affix my signature in presence of two witnesses.
F. P. HALE, I 0. HALE.
