POCKET KNIFE Filed OCL 25, 1930 fa 2411@ a] Patented Apr. 28, 1931 UNITED stares rAT'r ori-frcs HENRY VOSSLER, 0F PROVIDENCE, RHODE ISLAND, ASSIGNOR T0 IMPERIAL KNIFE COM- IPANY, NC., A CORPORATION OF RHODE ISLAND POCKE-TKNIFE Application filed Get-eher 25, 1930. Serial No. 491,110.

My invention relates to pocket-knives and more particularly to the type wherein a non metallic material is employed in the handle scales.

The essential objects of my invention are to provide rigid and unyielding areas in the handle halves for sustaining the end rivets which perform the functions of blade pintles, or pass through the s )acing block when such a blocl7 is employed in place of the second blade; to avoid the use of holsters whose mass involve heavy drilling operations; to guard, shield. and protect the constituent parts of the side members; to minimize the quantity of Celluloid or other expensive ornamenting material; and to facilitate, simplify, and cheapen the assemblage and interengagement of the constituent parts of the handle.

To the above ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a )art of this s iecitication Figure 1 is a side elevation of a pocket knife embodying my invention,

Figure 2, a vertical longitudinal section thereof,

Figures 3 and Ll, sections respectively on lines 3-3 and 1 -fl of Figure 1,

Figures 5, 6 and 7, perspective views of a cup member, a compensating plate, and a handle scale respectively, and

Figures 8 and 9, like views of the individual pivot retaining plates.

Like reference characters parts throughout the views.

ln the form of my invention herein illustrated my pocket knife consists of a handle represented in a general manner by 10 comprising side members 11 and 12 of identical construction in the present instance so that a indicate like description of one of the members will serveV for both, and simile r reference characters willr be employed for the corresponding parts of both members.

Two blades 14 are shown supported between the side members, although it is evident that the number of blades is immaterial,

and. that when one blade only is present the usual spacin g block replaces the second blade. rlhe tines of the blades engage the ends of any usual or desired back spring 16 provided with an opening 18 for the rivet.

The two metal frame pieces or companion plates 2O Awhich form the walls of the blade pocket have integral peripheral flanges 21 which constitute the side walls of a cup member 22 of which the frame pieces 20 constitute the bases, and the iianges 21, the sides. The

peripheral Icontours of the frame pieces are ofY any convenient -form to Ybest accommodate the blades or otherimplements desired to be mounted 1n the handle. Near they ends of the cups are perforations 2B, and intermediatev these, a perforation 24. Y

In each cup a metal compensation plate 25, of substantially the same peripheral contour and area as that of the base, and of any-pre-A ferred shape in cross section,vrests against the latter, and hasperforations 27 and 28 registering respectively with the perforatio- ns 23 and 24. Y

Resting against an intermediate portion of each plate is a handle piece or scale 30, of Celluloid, bone or any other similar non-V metallic material, and of any preferred peripheral outline or lof any preferred cross sectional shape, with its lateral edges contacting with the flange 21, andy provided with an intermediate perforation 31, registering with the perforation 28.

Resting against the end portions of each plate 25 are metallic attaching plates 32 and 33 of any preferred transverse or longitudinal sectional contour engaging the flange 2.1, and having inner edges abutting against the ends of the adjacent handle scale 30. lTheplates S2 and 33 have perfor-ations 36 registering with the perforations 27.

After the contentsof the cup members have been disposed therein as above described the upper transversely tapering peripheral edges of the 21, which abut against the peripheral edges o-f all the enclosed parts, are by suitable dies inwardly swaged-v over the marginal portions of the outer facesof the members 30, 32 and 33 and constitute retaining lips 38 which prevent lthepingress of dust and retain or assist in retaining the assembled parts.

The spring 16 is secured to each of the sides by a rivet 39 passing through the opening 18 and through the perforation 24 of the frame piece. In this instance this rivet also extends through the perfcrations 28 and 31 in the members 25 and 30, but this extension isnot essential and is preferably absent. The end rivetsY 4l pass through openings 43 in the tines of the blades leland through the perforations 23, 27 and 36 in both side members, so that the ends of the rivets are eX- panded into firm engagement With-the metallic attaching plates 32 and 33.

'lheV omission of holsters-in this structure eliminates the expense of heavy drilling, and the presence of the compensation plate 25 enables the employment of a minimum of material in the handle scale 30, Which material is comparatively expensive. The metallic attaching plates 32 and 33 insure firm interengagement of and seats Afor the blade rivets llLand a security which would be absent were the rivetsv to be expanded in a nonmetallic strip. The cup Amembers 22 protect and laterally house the various parts assembled therein. and the bases 2O of the cup members are utilized as frame pieces. The lips 3S may assist in securing the members 30, 32 and 33 'and make the presence of a rivet in the scales 30 unnecessary.

Without departing from the spirit of my invention other modes of applying the principles thereof may be employed than that eX- plained., change being made yin the construction herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I claim 1. In a knife-handle, a frame piece, a compensation plate engaging the frame piece, a handle scale engaging the compensation ,plate, attaching plates supported by the frame piece adjacent the ends of the handle scale, and a peripheral flange upon the frame piece engaging the peripheral edges of the handle scale, and attaching plates.A

2. In a knifefhandle, a cup member comprising a frame piece, and a lateral peripheral flange upon the frame piece, a compensation plate upon the frame piece, a handle scale upon the plate, attaching plates upon the compensation plate abutting against the ends of the handle scale, and a peripheral inwardly directed lip upon the fiangeengaging the handle scale and the attaching plates.

3. In a knife-handle, a frame piece, a handle scale supported upon the frame piece and of less length than the frame piece, attaching plates supported by the frame piece adjacent the ends of' the handle scale, anda peripheral flange upon the frame piece engaging the scale and the attaching plates.

4. In a knife-handle, a frame piece, a

handle scale supported by the frame piece, attaching plates supported by the frame piece adjacent the ends of the handle scale, a peripheral fiange upon the frame piece surrounding the scale and the pla-tes, and a lip upon the flange engaging the plates and scale.

5. In a pocket-knife, frame pieces, blades between the frame pieces, handle scales carried by the frame pieces and of less length than the frame pieces, attaching plates adjacent the ends of the scales, peripheral flanges upon the frame pieces engaging the scales and attaching plates, and rivets in the attaching plates engaging the frame pieces and the blades.

In testimony whereof I have affixed my signature. v

HENRY VOSSLER.
