3 Claims.

This invention relates to knives and, more particularly, to an improved knife handle.

It is an object of my invention to provide a knife handle whose covering means includes a thin non-metallic scale embodying a. metallic ornament which extends through an accurately matching aperture in the scale.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of Which the scope of application will be indicated in the claims.

In the accompanying drawings, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a side view of a knife embodying my invention;

Fig. 2 is a front view thereof;

Fig. 3 is an enlarged sectional view taken substantially along the line 33 of Fig. 1;

Fig. 4 is a back view of a finished covering means for one side of the knife handle;

Fig. 5 is a top plan view of a scale member comprising part of said covering means;

Fig. 6 is a top plan view of a combination scale holding and bolster or tip forming member, which comprises the other part of the covering means; and

Fig. '7 is a sectional view through a die used for the formation of the metallic ornament.

Referring now to the drawings, l denotes a knife embodying my invention and comprising a pair of spaced elongated lining sheets l2, l4 joined by a plurality of rivets l6, I8, 20. One of the rivets; It forms the pivot on which a knife blade 22 is rotatably mounted. The curved tang end of said blade bears against a standard resilient spacer 24 located intermediate the lining sheets I2, I4 adjacent one pair of longitudinal edges of said sheets.

The knife construction thus far described is conventional and provides a rough frame of which the two exposed faces of the lining sheets must be suitably concealed. For this purpose, each side of the frame has mounted thereon a covering means 25, 28 which may be fabricated, in general, in the manner shown and described in United States Letters Patent No. 2,284,833 issued June 2, 1942. Essentially, each covering means includes a combination scale supporting and. bolster or tip forming member 30 (Fig. 6) hereinafter called the "support and an ornamental scale member 32 (Fig. hereinafter called the scale.

The support is fabricated from sheet metal and comprises an elongated, interiorly concave stamping whose plan configuration conforms approximately to the plan configuration of that side of the knife frame on which it is adapted to be mounted. Bolsters or tips 34, 34 at the .opposite ends of the support exactly conform to the contour of the ends of the lining sheets which they overlie. An intermediate portion 36 of the support, which integrally connects the bolsters 34, 34, has a configuration similar to but smaller than that of the underlying part of the knife frame so that the scale, when superimposed thereon in a manner later described, will conceal the longitudinal edges of said portion and the entire covering member, including the scale and support, will jointly present a contour exactly matching the configuration of a lining sheet. The ends of the intermediate portion 36 are slightly lower than the bolsters whereby, when said portion is covered by the scale, the top surface of the scale will be substantially flush with the top surface of the bolsters.

The scale 32, which may likewise be fashioned from sheet material, comprises a plastic substance and preferably one which can be plasticized by heat and pressure, such substances including by way of example Celluloid, cellulose acetate, cellulose acetate butyrate, regenerated cellulose, cellulose nitrate, styrene resins and acrylic resins. If desired, plastic materials which can be plasticized in other manners may be employed, such materials including, for instance, phenol or urea formaldehyde resins. The scale has an elongated central portion 38 which overlies the intermediate portion 36 of the support and has lateral extensions 40, 42 bent around the edges of said intermediate portion, as described in said patent so as to secure the scale in position, said scale being locally plasticized where it is bent around the support.

Suitable means is also provided to secure the covering means 26, 28 to the knife frame. Said means may include tangs 44 integrally extending away from each end of the support and adapted to be forced into pockets 46 on the ends of the lining sheets l2, l4.

Pursuant to my invention, I incorporate a metallic ornament in the non-metallic scale in a novel manner which involves no extra expense for material and only a slight additional expense, if any, for labor. This is to be contrasted with previous practice, wherein, when metallic or-
