Specification of Letters Patent.

POCKET-TOOL.

Patented Feb. 4, 1908.

To all whom it may concern:

Be it known that we, AUGUST F. MnissnL- BACH and PLINY CATUCOI, citizens of the United States ,residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Pocket-Tools; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make, construct, and use the same.

Our invention relates to improvements in pocket tools, wherein the handle is made of a strip of metal U-shaped in cross-section and bent into a substantially elongated oval, the ends of said oval being brought together to form a fastening means for the blade of the screw driver or other implement to be used in connection with the improvement. The two arms of the handle are clamped against the face of the flat blade by means of a forrule which is secured in position by means of a bayonet joint.

In the accompanying drawings forming a part of this specification, Figure 1 is a plan view showing the blade of the imple ment extended. Fig. 2 is a side elevation of the same. Fig. 3 is also a side elevation, showing the clamping ferrule removed and the blade in the act of reversing. Fig. 4 is an end view of the device complete. Fig. 5 is an enlarged view of the clamping end of the handle, showing the blade in position, and also the structure of the handle itself. Fig. 6 is a view similar to Fig. 5, showing the clamping ferrule in position with the blade clamped between the ends of the jaw members.

Similar letters of reference refer to like parts throughout the specification and drawmgs.

The handle A is made of a strip of metal bent into U-shape in cross-section and also longitudinally into an elongated oval or pear shape, with the ends of the members brought together as shown in Fig. 5, to form the jaws a, a. The extreme ends of the jaws are-tapered or made conical as at b, 1). Back of the conical portion and towards the handle is a cylindrical portion a, c. In one limb or jaw a, we secure in the cylindrical portion 0, the outwardly projecting pin d. The jaws a from the cylindrical portion 0, extend rearwardly as clearly shown in the several figures to form the enlarged handle.

Between the jaws (L and located at some distance back from their points, is the shouldered cross pin 0, pivoted in the arms of the handle A, and held in position against accidental removal by means of the shoulders f. This pin carries the blade B of the tool, the pin 6 passing through an aperture in the face of the blade B, and riveted in position so that the blade B becomes pivoted and can swing around between the jaws a, a so as to bring either end of the blade into position for use, when desired.

In order to clamp the blade in position, and hold it against accidental displacement, we provide the clamping ferrule C, said clamping ferrule having a cylindrical internal portion 9 and a conical internal portion 7i, to receive the corresponding portion a and Z) of the jaw members of. In the side of the ferrule, we provide a bayonet slot '5, to receive the pin (1 on the jaw a.

When the blade B is adjusted in desired position, the ferrule O is restored to the cylindrical portion 0, c of the jaws with the pin d in the slot 01. The forward portion of the slot 1' is slightly inclined so that when the ferrule is given a slight turn, it will be crowded farther up on the jaws a, a, and the conical internal portion h of the ferrule will ride upon the conical jaw ends I), so as to bring them into bindin contact with the face of the blade B. Fn this manner, the blade B is firmly clamped between the aws a, (1 against displacement.

I/Vhile we have shown the blade as provided witha screw driver, yet we do not wish to limit ourselves to the use of a screw driver alone, as the blade may be provided with tools of various kinds at its point, as for example, the blade may be pointed to serve as a scratch awl it may be provided with a button hook; or it may be a saw blade, etc. etc.

The principal feature of our invention resides in the lightness of the handle being of the U-shaped metal construction, and also in the non-detachable, but reversible blade, together with the clamping means for securing said blade firmly into the handle.

We claim:

1. A pocket tool, comprising a handle composed of a strip of metal U-shaped in cross-section and bent into an elongated oval shape, to form a pair of externally tapered metal bent into an elongated oval, the ends clamping jaws, a flat blade or tool pivotally connected to said. jaws and a clamping ferrule detachably secured to said jaws to clamp the same to said blade or tool.

2. A pocket tool, comprising a handle, a pivoted blade or tool and a clamping ferrule, said handle consisting of a strip of hollow half round metal bent into an elongated oval with the ends thereof forming a pair of eX- ternally tapered clamping jaws to receive and clamp said pivoted blade, with the ferrule secured in position upon said jaws to prevent their separationl 3. A pocket tool, comprising a handle formed from 'a strip of hollow half round thereof forming a pair of tapered clamping jaws, a clamping ferrule having a tapered bore to receive said jaws, a bayonet slot in 20 said ferrule and a pin upon one of said aws. I

for cooperation with said slot to draw said jaws into clamping engagement with a blade or tool to be held therebetween.

, This specification signed and witnessed this 25 22nd day of November, 1907.
