IMPROVEMENT` IN KN IFE-GUARD.

The Schedule referred to in these Letters Patent and making part of the sama To all whom fit may concern:

Be it known that I, DAN PERRY, ot' North Providence, in the county ot'Provideuce, and State of'I Rhode Island, have invented a new and uset'ul Improvement in Knife-Guards; and Ido hereby declare that the t'ollowing is a full, clear, and exact description thereot', which will enable others skilled in the art to make and use the sal ne, reference being had to the accompanying drawings, forming part 0f this specication.

This invention relates to a new anduseful improvement in knife-guards for cutting-blades, and consists in-pivoting to the blade or handle of a knit'e, a metallic guard, so constructed that the thickness of the shaving is regulated by screws,and, when not wanted for use, can lbefolded into the. handle, leaving the blade free to be sharpened, cleaned, or Vused the same as if there were. no guard attached.

Figure 1' is a sideview.

Figure 2 is anledgc or back view.

'Similar letters ot' reference indicate corresponding parts in both figures.

To enable'others'skilled in the art to fully understand and construct my invention, I will proceed to describe it.

` A The spring-guard Gis constructed so as to embrace both a spring and guard, and .consists ota round wire, properly bent at both ends, to receive the pivot Pand screw S, the end at pivot P being bent like the main spring of a gun-lock. The long part is bent, at letter O, at right angles, to form the guard proper.

The pivot Pconsists of a machine-screw, Without thread, where it passes through the blade B, and a head, riveted, so that it cannot draw out, yet allowing 'it to turn easily in the blade B.

The screw S, on guard G, has a recess turned near the end, to receive the edge of' blade B. l

Tile projection E is fastened to the handle H, and pivot.P, passing through it, serves the double purpose ot' holding the upper end ot' pivot P, aud securing the blade B to handle H. Y

The guard Gis attached to the blade B by pivot P.

' The screw S, passing through the gua-rd G while in use, has its recess slipped on to the. edge ot' blade B, and is held in position by the spring on the end ot' guard G, under projection E, pressing against the handle H, or its equivalent.

The pivot P and screw S also serve to regulate the thickness of the shaving, which, by turning, raise and lower the guard G.

Folding the guard G, as seen in dotted lines in tig. 1, into the recess in handle H, leaves the.- blade free to be sharpened or used like any other knife.
