Specification of Letters Patent.

Patented Feb. 1, 191m.

Application filed February 19, 1909. Serial No. M8325.

To all whom it may concern:

Be it known that I, ISRAEL KINNEY, of the town of Paris, in the county of Brant, in the Province of Ontario, Canada, have invented certain new and useful Improvements in PocketKnives, of which the following is the specification.

My invention relates to improvements in pocket knives, and the object of the invention is to devise a simple, strong and cheaply made knife of a minimum number of parts.

A further object is to so construct the knife that the spring controlling the blade will both act as a spring and a back.

A further object is to make the knife of such a construction that another instrument may be readily combined therewith.

A still further object is to strengthen the blade at the heel against lateral swing.

To eifect these objects I have constructed my knife of two sides suitably stamped up and connected together by a back, which straddles the edges of the sides and is fastened to each back at each side by a central pin or the like. The end of the spring back is provided with a notch in which the butt of the blade fits, and the parts are otherwise constructed and arranged as hereinafter more particularly explained.

Figure 1, is a perspective view of the simplest form of my knife. Fig. 2, is a longitudinal section at right angles to the plane of the blade. Fig. 3, is a longitudinal section on a plane parallel. with that of the blade. Fig. 4, is an enlarged cross section on the line ilk-j] Fig. 1. Fig. 5, is a view of an alternative form. Fig. 6, is a longitudinal section through Fig. 5.. Fig. 7, is a cross section on the line my Fig. 5.

In the drawings like letters of reference indicate corresponding parts in each figure.

In Figs. 1, 2, 3 and l I show the sides of the knife and the end formed up in one piece, one end being curved and closed. The sides I designate A and the curved end, which forms part of the sides I designate A. B is the back, which is made of spring metal and has downwardly extending side lugs B through which extends the retaining pin 0, which also extends through thesides A near the back edge. It will be noticed that the back B straddles the knife,

that is to say is formed substantially reverse U-shape in cross section, so that the sides of the U extend over the back edge of the sides of the knife. The end of the back B at the blade is provided with a notch B D is the blade, which is pivoted on the pin D and is provided with the usual shoulder D which abuts the inner end of the notch B The sides of the notch B serve to relieve the lateral strain on the blade at the butt. B is a slit in the back B and A? is an orifice made in the end A beneath the open end of the slit E is a pencil case, which is held within the back B by means ofthe laterally extending double lip E forming part of the pencil case. In order to use the pencil case it may be slid longitudinally in the slit B until it reaches the outer end. The lip E having a lateral spring serves to hold the pencil case securely in the slot.

In Figs. 5, 6 and 7, I show a modification in which the sides A and A are formed separately. This is a double bladed knife and the side A has an outward fold A at the open side. The side A has an outward fold A. This outward fold forms substantially a socket A in which a scale or slide rule 3 may be inserted, thus also providing a socket for the reception of a separate instrument, which may be convenient to use with the knife. The instrument, of course, would depend upon the occupation of the owner of the knife. The back shown in Figs. 5, 6 and 7 is vertically formed to the back 13 shown in Figs. 1, 2, 3 and I.

It will, of course, be understood various changes may be made in the form of the knife and even the construction of the spring back without departing from the spirit of my invention.

What I claim as my invention is:

1. A knife having its sides formed up by being folded, a blade suitably held in the open end of the side, a spring back of U-form straddling the back edges of the sides, and means for holding the back to the sides.

2. In a knife, the sides formed up by being folded, a blade suitably held in the open end of the side, a spring back formed substantially U-shape incross section and straddling the back edges of the sides, and having depending side lugs and a pin extending through the side lugs and sides of the knife spring designed to hold the spring in posinear the back edge as and for the purpose tion in relation to the sides of the knife as specified. l specified.

3. In a knife, a spring back formed U- ISRAEL KINNEY.
