' TOOL HANDLE FASTENING llorsellil. Waters, Belmont, N. Y. Application June 6, 1950, Serial No. 166,477

This invention relates to knives and more particularly to large knives used principally by woodsmen and relates specifically to the handle construction of such knivesyit" of course being understood that the novel handle construction is capable of use with ,any kind of knife or other tool handle.

The main object of the invention is to provide a knife with the usual blade, the blade terminating in a handle supporting tang, said tang having stamped out from the metal thereof at its end a toothed locking pin having a plurality of formed teeth, which teeth engage the teeth and, the shoulders of corresponding teeth formed within the tang slot when the toothed wedge is driven home to lock the handle leathers upon the tang.

A further object of the invention consists in welding or otherwise suitably attaching the lock ing wedge to a solid metal cam member, whereby the wedge can be quickly and easily driven into its locking position with the tang by simply striking the cap with a hammer or the like.

Other objects and advantages will become apparent when considered in the light of the following description and accompanying drawings in which:

Fig. 1'is a side elevational view of the assembled knife; r

Fig. 2 is a view in side elevation with the handle leathers and knife guard in section and showing in detail the locking wedge in its assembled relation;

Fig. 3 is a perspective view of the handle cap and locking wedge; and

Fig. 4 is a detailed view of the end-of the tang showing the locking wedge removed.

Referring specifically to the drawings in which like numerals have been used to indicate similar parts throughout the various views, the knife blade is shown at'6, said blade having the usual cutting edge 1 and back 8. The blade 6 is further 2 Claims. (Cl. 30342) and rear discs, the discs thus gradually reducing in size from the center of the handleto the're'ar and front thereof to form a hand grip which will follow the contour of the users hand.

The tang 10 along its center portion and adjacent its outer end has stamped out'therefrorn as by a stamping die or the like a wedge shaped locking pin I2, said pin during thes'ta'mpin'g operation being cut to provide along its opposite sides or edges a plurality of ridge engaging teeth l3. The tang H] from which the locking pin I2 is die cut is left with a longitudinal slot [4 and inprovided at its rear end with a finger guard 9 as an integral part of the blade, which guard prevents the fingers and hand of the user from slipping into contact with the cutting edge of the blade when in use.

The blade 6 terminates in its inner end with a tang [0 which is somewhat reduced in size as respects the blade, the tang being rectangular in shape. A. multiplicity of oval shaped handle forming leather discs l I having rectangular slots therein, which slots are adapted to be of the same size as the tang whereby the same can be slid onto the handle tang ID, the intermediate discs being of larger circumference than the adjacent front wardly extending teeth portions I5 on opposite sides of the slot, the slot l4 further terminating at its innermost end in a circular opening lfi'which may have been previously cut therefrom, and it will be noted that by the removal of the die out looking lug I2 from the same material as that of the tang 10 that the side members I! and ill of the tang contain a certain natural resiliency which tends to urge theprongs l1 and I8 together or at least toward each other.

Each tooth I3 is provided along its respective less steel cap 2| of oval form to the central inner surface of which is welded or otherwisesecurely fixed the outer end or base of the locking pin I2. In the assembly of the knife handle, the tang I portion [0 is first die cut to remove thetoothed locking pin [2. Thereafter, the pin 12 is welded or fixed to the cap member 2l; After this has.

been accomplished, the plurality of oval shaped handle leathers l I' areprogressivelyfed onto the tang and of course in the proper relation to give shape to the handle. After the'handle leathers have been pushed onto the handle tang it is only necessary to take the toothed pin l2 and its cap and upon placingthe leading end of the pin in alignment with the slot l4, and thereafter striking the head 2| with a hammer or mallet to drive the toothed pin home, that is into the tang slot, whereupon the teeth l3 interengage with the teeth l5 of the tang which securely locks the cap 2| to the tang and in addition the inner face of thecap 2| engages the outermost handle leather and forces and holds'the same in tightly abutting the same it would be necessary to cut through a sufllcient number of the leathers to allow sidewise removal of the toothed pin. Thus, I have provided a very efiicient, time saving and low cost means of locking the various handle leathers of, a plurality of handle forming leatherv discs to a knife-handle. It will of course be realized I that the invention could readily be adapted for use not only with a, knife handle, but with many tool handles, such as hammers, chisels and the like, and the invention as disclosed is in the preferred form but'is capable of considerable 'variation and'modific'ation within the scope of the following claims.

I claim:

1. .A knife comprising in combination, a blade' provided with a rearwardly extending tang,-. a plurality of handle forming discs mounted upon and extending the full length ofthe tang, a handle cap having a toothed locking pin secured thereto, the tang having a toothed slot therein, the teeth of the locking pin and the "teeth of the toothed slot in locked engagement when the locking .pin is driven into the slot, the inner surface of the handle cap contactingtheoutermost discs to compress the same and hold the discs upon the tang,

2. A knife comprising in the combination, a blade provided with a rearwardly extending tang, said tang being substantially rectangular in shape and having a slot extending inwardly of mounted upon the tang, an end cap for the handle, and a toothed locking pin secured to the cap, and adapted to be driven into the tang slot whereby the respective teeth of the tang engage the teeth of the locking pin to prevent its withdrawal, the cap member engaging the outmost leather'disc and holding the plurality of discs upon the tang.
