Patented June 9, 1942 E KNIFE Henry Vossler, Providence, R. I., assignor to Imperial Knife Company, Inc., Providence, R. 1., a corporation of Rhode Island Application January 19, 1940, Serial No. 314,649

3 Claims.

This invention relates generally to knives. More particularly, this invention relates to an improved construction for knife handles.

One of the objects of this invention is to provide an improve knife handle construction of the character described in which an ornamental scale supporting member is attached to the knife in such manner as to present to the finished knife a smooth uninterrupted peripheral edge.

Another object of this invention is to provide an improved knife handle construction of the character described which shall be quickly and easily attachable to a knife frame in such manner that the same will be held in rigid attachment thereto and in which the means for effecting such attachment shall be concealed and protected.

Still another object of this invention is to provide a knife handle construction which shall comprise relatively few and simple parts, which shall be relatively inexpensive to manufacture, simple to assemble and which at the same time shall represent a general improvement in the knife art.

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 drawing, in which is shown one of the Various possible embodiments of this invention,

Fig. 1 is a top plan view of a knife constructed in accordance with this invention and having a portion of the outer covering thereof broken away to disclose the interior construction;

Fig. 2 is a cross-sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a cross-sectional View taken substantially on the line 3-3 of Fig. 2;

Figs, 4 and 5 are end elevational views of the knife illustrated in Fig. 1;

Fig. 6 is an elevational View of. the scale supporting member of the knife shown in Fig. 1 but removed therefrom and viewed from the underside thereof; and

Fig. 7 is a top plan view of one of the plates shown in Fig. 2, but disassociated from the knife frame.

Referring now in detail to the drawing, there is disclosed a knife constructed in accordance with my invention, such construction being of the type generally disclosed and described in Patent No. 2,170,537, dated August 22, 1939, for Knife handle and component parts thereof, and comprises a pair of knife blades l0 and H pivotally mounted in a frame. The said frame comprises the parallel, spaced plates |4, l5 and I6, held together by suitable rivets iii. The blade H in closed position is received in the housing space A formed between the plates I4 and I5 while the blade ID, in closed position, is received in the housing space B formed between the plates I5 and I6. As fully described in the said Patent No. 2,170,537, knives of the character herein described are provided with a pair of ornamental scales I1 and I8 which may be of any suitable material such as a plastic material and which may also be mounted on scale supporting members H! and 29. The said scale supporting members l9 and 20 may be of the type having pairs of bolsters lQa and 29a at the ends thereof and in which the ornamental scales l1 and I8 are disposed between the pairs of bolsters.

In knives of this type the method of assembly relating to the attachment of the scale supporting members to the knife frame heretofore consisted of providing the said supporting members with a pair of prongs at the extreme opposite ends thereof, which prongs were received in corresponding notches cut in the extreme ends of the frame plates.- By such construction it was found that, when completely assembled, the said prongs and notches were visible at opposite ends of the knife, often resulting in a break in the peripheral contour of the knife when viewed from the top or ends. This detracted materially from the appearance of the knife and was additionally a weak point in the knife assembly,

In accordance with the present invention, therefore, I have provided the following novel means for attaching the scale supporting members I9 and 20 to the frame, whereby the smooth unbroken uniformity of the peripheral contour of the knife is preserved. As clearly shown in Figs. 2, 3 and 6, each of the scale supporting members l9 and 20 is provided with a pair of projections 2| and 22 which may be struck out from the material of the supporting members l9 and 20. It is noted that the pairs of projections 2| and 22 are spaced a predetermined distance inwardly from the ends of the said supporting members l9 and 2|] and between the pairs of bolsters |9a and 20a. The said projection 2| and 22 are designed to be received in corresponding openings 23 and 24 in the frame plates I4 and I6. The portions of the projections 2| and 22 passing through the said openings 23 and 24 and into the spaces A and B are folded over as shown, to thereby retain the supporting members l9 and 20 in fixed attachment to the knife frame.

In view of the above described construction, the uniformity of the peripheral contour of the knife is maintained unbroken throughout, as clearly shown in Figs. 1, 4 and 5 of the drawing. In order not to interfere with the free pivotal movement of the blades I0 and II within the spaces A and B, portions 14a of the plate [4'- and portions lBa of the plate l6 adjacent the openings 23 and 24 are slightly depressed to permit the inturned portions of the projections 2| and 22 to lie flush with the inner surfaces of the plates I4 and IS.

The knife constructed in accordance with this invention and described above facilitates quick and simple assembly due to the fact that the supporting members l9 and 2E! may be stamped with the projections 2| and 22 and the frame plates I4 and I6 ma also be stamped'with the openings 23 and 24 and the offset portions I 4a and [6a. In attaching the scale supporting members 19' and 20' to the frame, it is merely necessary to place the projections 2| and 22. in the corresponding openings, after which, by means of a suitable tool, the ends of the projections 2| and 22 in the spaces A andB are merely bent over.

It willthus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted.

comprising a plate having apertures therethrough, a scale supporting member comprising tips or bolsters and a depressed portion interconnecting said bolsters, downwardly projecting tongues in said depressed portion, said tongues being received in said plate apertures and having portions thereof bent over to lie parallel to the plane of said plate, and recessed areas in said plate adjacent said apertures, said bent over tongue portions being received in and completely filling without projecting from said recessed areas.

2. In a knife handle construction, a frame comprising a plate having apertures therethrough, a scale supporting member comprising tips or bolsters and a depressed portion interconnecting said bolsters, downwardly projecting tongues in said depressed portion, said tongues being received in said plate apertures and having portions thereof bent over to lie parallel to the plane of said plate, recessed areas in said plate adjacent said apertures, said bent over tongue portions being received in and completely filling without projecting from said recessed areas, and an ornamental scale member on said supporting member, said scale member being disposed in said depressed portion between said bolsters and concealing the openings therein formed by said struck out projections.

3. In a knife handle construction, a knife receiving compartment, one side of which comprises a plate, a scale supporting member, and means to support said member on said plate, said last named means comprising downwardly projecting tongues on said supporting member and cooperating pockets in said plate, said pockets being struck away from said knife compartment and-provided withapertures to receive said tongues, said pockets being of sufficient depth to full accommodate said tongues without permitting the same to project into said knife compartment, said tongue substantially filling said pockets.
