EDMUND PBIESTMAN, OF SHEFFIELD, ENGLAND.

POCKET-KNIFE AND TOOL-PAD.

Specification of Letters Patent.

Patented Nov. 15, 1921.

Application filed March 19, 1920. Serial No. 367,150.

T 0 all whom it may concern Be it known that I, EDMUND PRIns'rMAN, a subject of the King of Great Britain and Ireland, residing at heffield, in the county of York, England, have invented new and useful Improvements in or Relating to Pocket-Knives and Tool-Pads, of which the following is a specification.

This invention relates to pocket knives and tool pads of the kind in which the blade portion is pivotally mounted in a bowed spring handle with longitudinal grooves to hold the blade rigidly in position, and which blade can be turned sidewardly so as to lie within the hollow portion of the handle. My invention consists in a simplified construction of such knives and tool pads by making the tang of the blade portion with square edges and square projecting pegs, and the bowed spring handle with a rounded longitudinal inner groove in the form of an expanded U with outwardly splayed sides.

My invention will be better understood on reference to the accompanying drawings in which Figure 1 is a front elevation of the form of handle I employ for holding an implement such as a blade.

Fig. 2 is a right hand end view of same.

Fig. 8 is a side elevation of a blade adapted to fit into said handle.

Fig. 4 is an edge view of same.

Fig. 4 is a cross section on the line A B Fig. 3.

Fig. 5 is a view of a handle and blade assembled.

Fig. 6 is an edge view of same.

Fig. 7 is a cross section on the line C D Fig. 6.

The same letters refer to similar parts throughout the several views.

In order to reduce the relatively large amount of labor entailed in the manufacture of implements of the class to which my invention relates, I make the handle a of a bent strip of metal rolled with a rounded or splayed U groove a The handle a has two holes a formed in it, to serve as bearings for the pegs of the blade.

The blade .7) as shown in Figs. 3, 4 and 4 is of uniform thickness at the tang portion 6 and the edges 6 are at right angles to the face of the tang portion. The pegs b are rectangular, square or approximately square in cross section and of any convenient length.

6 are shoulders formed on the tang, said tang tapering from said shoulders to the pegs 6 It will be readily understood that the tang portion of such a blade can be cut to its finished form at one operation.

It will be seen on reference to Fig. 5, that when the blade and handle are assembled (and whether in the open position as shown in full lines, or in the closed position shown in dot-ted lines) the angular corners only of the tang portion 6 of the blade, bear against the face of the rounded groove a and in like manner the corners of the pegs b bear against the sides of the holes of, as shown in Fig. 6.

Two parallel grooves may be formed in the handle so that two blades can be carried at the same time. Likewise in the case of handles carrying only one blade, an additional implement such as a screw driver, can opener, or other suitable article may be formed on the rear end of the tang portion of the blade.

I am aware that it has hitherto been known in connection with implements having a blade or tool portion adapted to fold into a U shaped handle, to employ a handle with an internal rounded or U shaped groove, and for the shank of the implement to be adapted to the shape of and to fit into the contiguous grooves of the handle, and for the pivot pins on which the implement turns, to be of a corresponding sectional contour to the holes in the handle with which they engage, and I do not claim as my invention any such forms of construction.

Having now described my invention, what I claim and desire to secure by Letters Patent is 2-- A pocket knife and tool pad, comprising a U-shaped metallic handle having a groove on the inner side thereof, said handle being provided in each prong near its end with a round opening, a tool adapted to lie within the handle in its closed position, a tang at one end of the tool and provided with square shoulders, said tang being of uniform thickness and having rectangular pegs projecting from the edges and adapted topivot in the openings in the handle, said tang tapering from the shoulders to the pegs.

In testimony whereof I have signed my name to this specification.

EDMUND PRIESTMAN.
