6 Claims.

This invention relates to knives of that type provided with a finger rest operating over the unsharpened edge of the knife blade adjoining the inner end of the handle and has for its object the provision of a finger rest construction and mounting. therefor, that will firmly and securely anchor the finger rest in position and so hold it there thatit will have no tendency to become loose or be capable of any appreciable movement relatively either to the blade or to the handle of the knife.

With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevation of a knife constructed in accordance with the present invention;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is an elevation of the knife as viewed from the point of the blade thereof; and

Fig. 4 is an elevation of the end face of the ferrule mounted on the inner end of the handle of the knife, showing the construction by which it cooperates with both the finger rest and the shank of the knife blade.

Heretofore in the construction of knives embodying finger rests, it has generally been customary to either form the finger rest integrally with the unsharpened edge of the blade adjoining the inner end of the handle; or to provide a laterally disposed extension at the inner extremity of the finger rest, having an opening thereinfor the passage of the blade shank whereby the extension is clamped between the inner end of the handle and the inner extremity of the blade; or to provide a tongue or tongues at the inner end of the finger rest which are driven into the handle upon each side of and usually flush against the shank of the blade. These prior constructions are open to certain objections, principally because of the finger rest frequently becoming loosened and having some appreciable movement relatively to the blade and handle.

The present invention contemplates a finger rest that will be securely and firmly held in its position with reference to the unsharpened edge of the blade adjoining the inner end thereof and which will be substantially incapable of becoming loosened or having movement relatively to either the blade or the handle, thereby overcoming the principal objections to most forms of finger rests which have gone before.

Reference being had more particularly to the drawing, II] designates the handle of a paring knife having any suitable shape and size and being formed from any adaptable material, preferably and usually of wood. A knife blade II, provided with a shank I2, is attached to the handle I by having the shank I2 embedded in the handle II]. This shank I2 may be held in its position within the handle I0 by friction but if so desired, a headed pin or brad I3 may be driven into one side of the handle I0 to engage said shank I2 thereby firmly holding the shank in the handle ID.

The inner end 'of the handle I0 is shouldered, as at I4, and has a ferrule I5 mounted thereon. The outer extremity I6 of the ferrule I5 is closed by a face which covers the end or inner end of the handle I0 and through which the shank I2 must pass to become embedded in said handle. To that end a vertical slot I1 is provided in the face lfi of the ferrule and is crossed and intercepted by a horizontal slot I8 likewise formed in the face. I6. These slots I! and I8 are positioned centrally with respect to the diameter of the ferrule I5 and cross or intercept each other at the approximate center of the face I6 of the ferrule. The shank I2 of the blade I I passes through the vertical slot I I in the face I6 of the ferrule I5 and rather snugly occupies the entire slot. Thus when the shank I2 of the blade II is in its operative position, the ferrule I5 is fixed on the reduced or shouldered extremity I4 of the handle I0 and any tendency for movement thereof with reference to either the handle ID or the blade I I is largely overcome.

A finger rest I9 of any suitable shape and construction bears over the inner end portion of the unsharpened edgeof the blade I I and provides or creates a relatively wide rest for the index finger of the user of the knife. The inner extremity 28 of the finger rest I9 is bent downwardly at substantially right angles to the body of the finger rest to occupy a position fiush against the face I6 of the ferrule I5. This right angularly disposed extension of the finger rest I9 terminates in substantial alignment with the horizontal slot I8 in the face I6 of the ferrule I5.

At its extremity this right angularly disposed extension 20 of the finger rest I 9 is provided with two tongues 2| spaced one from the other laterally of the extension and extending rearwardly therefrom upon each side of the shank I2 of the blade II. One of these tongues passes through each portion of the slot I8 in the face I6 of the ferrule upon opposed sides of the vertical slot I1 and therefore may be and are embedded horizontally in the inner end portion of the handle I0 flanking and adjoining the shank [2 of the blade I I which rests vertically within the handle.

Movement of the finger rest I9 laterally with reference to the plane of the blade II, or to the handle I0, is effectively prevented by the engagement of the tongues 2I with the limits of the slot I8 in the face I6 of the ferrule I5 and any movement of the finger rest I9 longitudinally of the blade II and away from the handle I0 is prevented by the partial engagement of the extension 20 of the finger rest I9 between the inner extremity of the knife blade II and the face I6 of the ferrule I5.

This construction provides additional security over and above the normal frictional engagement of the tongues 2| with the handle I0 for holding the finger rest I9 firmly and securely in position.

From the foregoing it is manifest that the present invention provides a mounting for a finger rest cooperating with the unsharpened edge of a knife blade that will prevent the finger rest from becoming loosened or having any substantial or noticeable movement relatively to the knife blade or to the handle of the knife. In other words, any turning action of the blade II, ferrule I5, or finger rest I9 with respect to the handle I0, is effectively overcome by the coaction of the shank I2 and the tongues 2I with the slots I1 and I8 of the ferrule and with the body of the handle I0.

What is claimed is:

1. In a knife, the combination with a blade having a handle shank at one extremity thereof, of a handle adapted to receive and engage said shank, a finger rest coacting with the inner end portion of the unsharpened edge of the blade, a ferrule mounted on the inner end of said handle having a closed outer end and a vertical slot therein for the passage of the handle shank and a horizontal slot crossing said vertical slot, and means on said finger rest to' be engaged in said horizontal slot to mount and hold said finger rest against movement.

2. In a knife, the combination with a blade having a handle shank at one extremity thereof, of a handle adapted to receive and engage said shank, a finger rest coacting with the inner end portion of the unsharpened edge of the blade, a ferrule mounted on the inner end of said handle having a closed end and vertical slot therein for the passage of the handle shank and a horizontal slot crossing said vertical slot, and a rearwardly extending tongue on said finger rest adapted to pass through said horizontal slot to rest within the handle aforesaid.

3. In a knife, the combination with a blade having a handle shank at one extremity thereof, of a handle adapted to receive and engage said shank, a finger rest coacting with the inner end portion of the unsharpened edge of the blade, a ferrule mounted on the inner end of said handle having a vertical slot therein for the passage of the handle shank and a horizontal slot crossing said vertical slot, and rearwardly extending tongues carried by said finger rest adapted to pass through said horizontal slot and be embedded in said handle upon each side of the handle shank aforesaid.

4. In a knife, the combination with a blade having a handle shank at one extremity thereof, of a handle adapted to receive and engage said shank, a finger rest coacting with the inner end portion of the unsharpened edge of the blade, a ferrule mounted on the inner end of said handle having a closed outer end and a vertical slot therein for the passage of the handle shank and a horizontal slot intercepting said vertical slot, a right angularly disposed extension on said finger rest, and rearwardly extending tongues on said extension adapted to pass through the horizontal slot aforesaid and be received or embedded within the handle upon each side of said handle shank.

5. In a knife, the combination with a blade having a handle shank at one extremity thereof, of a handle adapted toreceive and engage said shank, a finger rest coacting with the inner end portion of the unsharpened edge of the blade, a ferrule mounted on the inner end of said handle having a. closed outer end and a vertical slot therein for the passage of the handle shank and a horizontal slot intercepting said vertical slot, a right angularly disposed extension at the inner end of said'finger rest positioned between the inner endof the handle and the inner extremity of the blade, and rearwardly extending tongues on said extension and spaced laterally'one from the other to pass through said horizontal slot upon each side of the handle shank and be embedded in said'handle.

6. In a knife, the combination with a blade having a shank at one extremity thereof, of a handle adapted to receive and house said shank, a finger rest'coacting with the unsharpened edge of the blade, means for'engaging said finger rest in position to be held against longitudinal movement with reference to the knife blade including a ferrule mounted on the inner end of said handle, and a tongue and slot connection between said ferrule and said finger rest for holding the latter against lateral movement with reference to the knife blade.
