WILLIAM ROCKWELL CLOUG-H, OF ALTON, NEW HAMPSHIRE.

POCKET IMPLEMENT.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 28, 1918. Serial No. 242,342.

To all whom it may concern:

Be it known that I, WILLIAM ROCKWELL CLOUGH, a citizen of the United States, and a resident of Alton, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Pocket Implements, of which the following is a specification.

The invention pertains more particularly to pocket implements of the character known and classed as pocket vknives and comprising a handle and suitable tools pivoted between the sides thereof and to fold therein, these tools sometimes consisting of cork screws having a worm portion and an integral tang, as heretofore made. There has not been much difficulty connected with the manufacture of pocket-knife handles, but considerable expense has been involved in the manufacture of the cork-screws intended to be pivotally secured between the opposite sides of said handles.

Thepurpose of my invention is to materially simplify and lessen the cost of manufacture of cork-screws for handles of the pocket knife type, and in carrying out my invention I form the worm of the screw and the tang therefor in separate pieces capable of being properly assembled and applied tothe handle. The tang will usually be of a different character of metal from that of the body of the worm of the corkscrew, and it will be formed from a block or blank of untempered stock, and the tangblank will have a socket therein to receive the shank-end of the worm, and finally I will preferably secure said shank-end in said socket by driving portions of the blank between integral portions thereof, after which the blank will be finished off to con, stitutea tang of the requisite shape and dimensions. The material of the tang blank may be readily hammered, ground and drilled, and in addition may be of a metal which would insure smoother or' easier opening' and closing movements of the cork-screw than is customary in instances in which the body and tang of the cork-screw are in one piece of tempered or hardened steel and in which the hardened tang is to move against the inner side surfaces of the parts of the handle.

The advantages of my invention may be readily appreciated in considering its use in the manufacture of cork-screws for pocket knife handles. These cork screws have heretofore been of forged metal, and the body and tang thereof have been in one piece and in the customary and regular manufacture these cork-screws have added materially to the expense of the pocketknife, which expense vmy invention materially'lessens and at the same time improves the character of the cork-screw for practical purposes.

In accordance with my invention I form the body or worm of the cork-screw from arod of wire, spirally coiled, and the tang thereof is a separate piece in which the shank end of said body is secured, said tang being formed from a blank and adapted for correct application to a handle of the'pocket knife type. It will appear obvious that the cork screw of my invention is simpler and -less*expensive than the one piece forged metal cork-screws that have heretofore been universally employed in pocket knives.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the ac companying drawings, in which:

Figure 1 is a side elevation, partly broken away, of a pocketrknife having its corkwith andjembodying the invention, said member being illustrated as opened outwardly from said handle;

.screw member constructed in accordance Fig. 2 is a side elevation, partly broken away and partly in section and on an enlarged scale, of the cork-screw worm and blank for the tang thereof illustrated in their preliminary associated relation;

Fig. 3 is a transverse section through the same, taken on the dotted line 3-3 of Fig. 2;

Fig. 4 is a corresponding section of the same illustrating the tang-blank having had its opposite sides driven inwardly between portions of the shank of the worm for fasand 18 being presented as illustrative of the various implements commonly employed in connection with pocket-knife handles.

The blade 16, cork-screw 17 and gimlet 18 are shown in Fig. 1 as'secured to finished tangs numbered, respectively, 19, 20 and 21, and these tangs are secured to the handle 15 by means of customary pins numbered, respectively, 22 and 23.

Figs. 2 to 5 inclusive illustrate the method of carrying my invention into effect, as applied to the cork-screw 17 and tang 20 thereof. The body of the corkscrew 17, in accordance with my invention and which is one of the advantages thereof, is formed from a rod of wire spirally coiled to form the worm in the customary manner, and the tang 20 is formed from a separate blank, block or piece of metal numbered 24 in Figs. 2 to 5 inclusive. The blank 24 is of suitable dimensions to be shaped into the tang 20, which in finished outline may correspond with the cork-screw tangs to be found at present in pocket-knives and which are integral with specially forged and wrought worms.

The blank 24 is preferably of rectangular outline and of suitable length, width and thickness, and at one end the blank 24 is formed with a socket 25 to receive the folded-over end 26 of the shank of the corkscrew 17, and which end has its

members

27, 28, except where they merge into each other, spaced apart, the member 28 setting off at an angle to the member 27 and an approximately inverted V-space 29 being left between said members. The end 26 of the cork-screw shank is inserted within and, by preference, tightly binds againstthe walls of the socket 25 in the blank 24, this feature of the construction, aside from other advantages, serving to properly aline the corkscrew and blank; and after said end 26 is properly seated within the socket 25, I drive one or both sides of the blank 24, at the location of the V-space 29, inwardly against and between the

members

27, 28 of said end 7 26, so that the blank becomes transformed from its initial condition shown in Fig. 3 to that illustrated in Fig 4, in which I indicate that both sides of the blank have been driven or pressed inwardly against and between the

members

27, 28. The pressing inwardly of the sides of the blank 24 against and between the members or

portions

27, 28 of the shank of the cork-screw has the effect of rigidly connecting said blank and corkscrew in a very eflicient manner and without any further securing means being required. The driving inwardly of the sides of the blank 24 results in a displacement of portions of the metal of the blank and this creates in said sides the grooves or indentations 30, which I remove by grinding downthe faces of said sides until said indentations disappear, leaving the blank with smooth opposite faces, as I represent in FVhen the stage of manufacture indicated in Fig. 5 has been reached, the cork-screw and tang-blank securely connected there with will be subjectedto such further treatment as said blank may require to shape and proportion it for the handle 15 and back-spring 31 therein.

In carrying out my invention I may depress one or both sides of the blank 24 against and between the

portions

27, 28 of the shank of the cork-screw but preferably both of said sides will be so depressed, as I illustrate, in order to secure a highly efficient connection of the tang-blank and worm. p p

The portion 28 of the shank end 26 of the cork-screw will be placed at that edge of the blank 24 which in the finished tang will be at the inner edge thereof when the the cork-screw isturned into the handle 15, so that the body of the worm will be eccentric to the pivot-pin 23 and lie exposed within the side-recess 32 of the handle 15, as will be understood on reference to Figs. 1 and 2. p

'In accordance with my invention the worm of the cork-screw may be formed of spirally coiled wire, such as has been found effective in the practical manufacture of 7 cork-screws, as distinguished from corkscrews made from metal wrought and public. In addition, the' cork-screw constructed in accordance with my invention is more eflicient than the cork-screw heretofore placed in pocket-knives madeof forged metal.

What I claim as m invention and desire to secure by Lettersatent, is:

1. A handle comprising opposite sides and a back spring, having, in combination, a tang cooperating with said spring and pivotally secured between said sides, and a spirally coiled wire cork-screw having a" The presence of the" worm and shank in one integral piece, said shank having at its outer en a folded over portion or return bend, and said tang having a socket holding said outer end of said shank and also having a portion of its metal interposed between portions of the members of said return bend.

2. A handle comprising opposite sides and a back spring, having, in combination, a tang cooperating with said spring and pivotally secured between said sides, and a spirally coiled wire cork-screw having a worm and shank in one integral piece, said shank having at its outer end a folded over portion or return bend, and said tang having a socket holding said outer end of said shank and also having a portion of its metal interposed between portions of the members of said return bend, and the pivot for said tang being set off from the central longitudinal plane of the body of said Worm.

3. A handle comprising opposite sides and a back spring, having, in combination, a tang cooperating with said spring and pivotally secured between said sides, and a spirally coiled wire cork-screw having a worm and shank in one integral piece, said shank having at its outer end a space between contiguous portions thereof, and said tang having a socket holding said outer end of said shank and also having a portion of its metal interposed into said space.

Signed at Alton, in the county of Belknap, and State of New Hampshire, this 26th day of June A. D. 1918.
