ROBERT L. morrn'r'r, OF CHICAGO, ILLINOIS.

Application filed May 28,

,binations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a kitchenknif which consists "of means for holding an ordinary safety razor blade of a well known type firmly in such a position that one edge of the razor blade serves as a cutting edge for the device, while the opposite edge of the razor blade is sheathed to insurethe back edgeof the device being blunt. I

A further object of my invention is to provide a device of the type described that is particularly suitable for use in cutting and paring fruit, vegetables, and the like, cutting cloth, paper, threads and any light household work requiring a device having a sharp cutting edge.

A further object of my. invention is to provide a device of the type described in which means is provided for utilizing safety razor blades whichwould otherwise be discarded and thrown away.

A further object of my invention is to provide a device of the type described that is inexpensive to manufacture effective in service, and thoroughly practlcal commercially.

Other objects andadvantages will appear in the following specification, and the .novel features of the, invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in wh1ch- Figure 1 is a plan view of the device, a part therecf being shown out of operative position, v

Fig. 2 is a plan view of the device completely assembled,

Fig. 3 is a side elevation of the device, a portion being broken away and portions being shown in section, j

Fig. 4 is a view of the op osite side of the device to that pictured in ig. 2, a portion of the device'being broken away.

Specification of Letters Patent. Patented Nov. 23, 1920.

ieeo. Serial No. 384,905.

In carrying out my invention, I provide ahandle .1 having aferrule 2. The shank 3 of-a' blade holding member 4 is inserted within a central slot 3 in the handleand is maintainedtherein by the binding action of the ferrule .2; ,member 4 has an arrow-shaped remote en provided with converging cutting edges 6 and 6, making the same suitable for use in removing eyes, spot, and the like from potatoes, cores from fruit, and in similar uses.

' The plate supporting member 4 has studs 7 which are located in alinement with the median line of the handle 1. A safety.

razor blade 8 of a well known type is placed in position on the blade supporting member 4, the studs 7 projecting through openings 26, which are ordinarily provlded in the safety razor blade.

It is to be noted that one cutting edge 9 of the razor blade projects beyond the adjacent edge 10 of the blade supporting member 4 and that, the opposite edge 20 of the blade supporting member projects slightly beyond the adjacent cutting edge 11 of the safety razor blade. Inorder to maintain the safety razor blade rigidly in position, I- provide aspring clamping member 14 which has a depressed tongue onkeeper 13. The latter is arranged to enter a slot 12 provided in the shank of the blade supporting member 4 adjacent the handle 1. I The spring clamping member 14 is then pressed downwardly in the direction of the .razor blade 8 and is moved laterally until a hook 16, which is provided at the other'end of the W en it is de-" The blade supporting sired to disassemble the device, as for instance, to replace the razor blade or to reverse the same to present a new cutting edge, it is only necessary to place an article, such as a lead pencil, against the portion of the hook 16 that projects beyond the re-' cess. .17 and to move the hook laterally by pressure against the same. The resiliency of the spring clamping member 14. will cause the same to move upwardly, the depressed tongue or keeper 13 acting as afulcrum.

vmember 4 is beveled at 22 and the It is to be noted that the side edges 21 and 24 of the clamping member 14 coincide With the edges 20 and 10 respectively of the blade holding member 4 when the device is in its assembled position. Consequently,

the comparativelyblunt edges 21 and 20 extend beyond the sharp edge 11 of the safety razor blade 8 and provide a non-cutting back for the device. The sharp edge 9 of the safety razor blade projects beyond the edges 24 and 10 of the clamping member 14 and the blade supporting member 4 respectively, providing a cutting edge for the device.

Since the clamping member 14 and the blade supporting member 4 are relatively wide in extent and cover a greater portion of the surface of the safety razor blade, the latter is rigidly clamped therebetween. The blade supporting member 4 flares at 18 and 19, as best seen in Fig. 2, to provide a guard to protect the hand if the latter should slip from the handle 2. The blade supporting spring clamping member 14 is beveled at 23, the edges 10 and 24 being sharp. Consequently, the blade supporting member 4 and the spring clamping member 14 do not interfere with the cutting operation of the device but extend sufiiciently near the cutting edge 9 to insure the flexible razor blade being rigidly held in position. Furthermore, portions of the articles out, such as fruit, cannot penetrate between the blade supporting member 4 and one side of the razor blade and the spring clamping member 14 and theother sideof the razor blade When the device is being used. The ends of the studs 7 are sunk below the surface of the blade supporting member 4 and the spring clamping member 14 When the device is in its assembled position, as pictured in Fig. 2, and do not interfere withthe operation of the dev1ce. I

'From the foregoing description of the various 'p'arts of the device, the operation thereof may be readily understood and requires no detailed description. My improved kitchen knife comprises an effective and economical means for performing light household work, such as hereinbefore described.

I claim:

1.,A device of the class described comprising a handle, a relatively wide blade supporting member carried thereby, said member being formed With studs arranged to project therefrom, said studs being positioned in alinement with the median line of said handle, whereby one side edge of a safety razor blade projects beyond the corresponding side edge of the blade supporting member when the former is placed on the latter, the studs being projected through openings provided in the razor blade, and a spring clamping member for holding said razor blade in position, said clamping member being formed with a depressed tongue at one end arranged to enter a slot in the shank of the blade supporting member, said clamping member having an opening positioned to receive each of the studs which blade and being formed with a hook arranged to engage the blade supporting member adjacent its remote end, whereby the razor blade is rigidly clamped in position, the side edges of the clamping member coinciding with the side edges of the blade supporting member, one cutting edge of the razor blade being sheathed therebetween.

2. A device of the class described comprising a handle, a blade supporting member consisting of a body portion having a shank inserted in the handle, and an end portion .formed With converging cutting edges, said shank being provided with a slot and said body portion being formed with spaced apart studs projecting therefrom, said studs being adapted for projection through openings in-a safety razor blade when the latter is placed thereon, whereby one of the side edges of the razor blade pro,- jects beyond the side edge of the blade supporting member, and -a spring clamping member adapted to be removably secured to said blade supporting member to rigidly clamp the razor blade therebetween, said spring clamping member being formed with a depressed tongue at one end thereof adapted to enter the slot provided in the shank of the blade supporting member, spaced apart openings adapted to receive the projecting ends of the studs, and a hook at the other end of the spring clamping member adapted to engage the blade supporting member adjacent its remote end, whereby one cutting edge of the razor blade is sheathed between the blade supporting member and the spring clamping member, forming a blunt
