UNITED STATES GEORGE A. COLTON, OF CHICAGO, ILLINOIS.

SCREW-DRIVER.

SPECIFICATION forming part of Letters Patent No. 438,097, dated October 7, 1890.

Application filed April 18, 1890. Serial No. 348,500. (No model.)

To all whom t may concern:

Beit known that I, GEORGE A. CoLroN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Screw-Drivers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in pocket implements, such as screw-drivers 5 and it has for its object, among others, to provide a device of this character which can be carried upon a key-ring or will serve also as a key-ring, if desired, and in which dierent sizes of screw-drivers may be embodied, the device comprising, essentially, two jaws pivotally connected together and formed upon one side of their` pivot in the form of a screw-driver and upon the opposite side of said pivot with broken rings or bows adapted when in one position to provide a communication to the space inclosed within the rings or bows to permit it to be placed upon a key-ring or to receive keys, as preferred, and when in the other position the separation thereof will be prevented. At or near the ends of the broken bows or rings I provide teats or projections to prevent their being opened except by direct pressure in the proper direction. rIhe device is applicable also for other uses-for instance, for securing show goods and cards to a line or wire.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part vof this specification, and in which- Figure l is a side view of my improved device, showinga card in dotted lines.. Fig. 2 is a like view with the parts in such position as to admit a ring or other device. Fig. 3 is a plan of Fig. l, and Fig. e'. is a plan of Fig. 2.

Like letters of reference indicate like parts in all the figures of the drawings.

Referring now to the details of the drawings by letter, A and A designate the two parts of the device pivotally connected together by the transverse rivet a of any suitable construction. Each of these parts A and A consist of a shank or arm, the free end of which is tapered or sharpened, as shown at b, Figs. 3 and 4, and at the other end, upon the opposite side of the pivot, with a ring-like portion B, which, however, is not a complete ring, but is what I term a broken ring or bow, it having an opening c, as shown best in Fig. 2. In practice the two arms or Shanks maybe of the same size both as to length, breadth, and thickness, or they may be of different length, different widths, or different thicknesses, as preferred, it being designed, generally, to have them of dierent sizes, so as to provide two sizes of screw-drivers, the said shank, as it will be readily understood, being formed into screw-drivers. lThe openings in the two ring portions are arranged in different planes-that is, upon opposite sides of a line drawn centrally through the arms and pivot, so that when the two arms are closedr upon each other in the same plane, as shown in Fig. l, a portion of one ring will overlap the break in the other, as indicated in full lines in said Fig. l. i

lVhen it is desired to open the ring to. receive a line, wire, or other obj ect, or t0 place the device upon a key-ring, one of the arms is turned at an angle to the other, as shown in Fig. 2, so as to bring the openings in the two ring portions coincident.

At or near the ends of the broken Wings or bows I form oppositely-arranged teats or projections OZ, as shown best in Fig. 3, which as the parts are closed increases the friction be tween the said part-s and serves to hold them closed and prevent their being opened except by direct pressure in the proper direction, as will be readily understood from Figs. 3 and 4.

WVhen it is designed or desired to use the device for the purpose of suspending cards or analogous objects from a line, the rings are opened to enable the same to be placed upon the line and the card placed between the two arm portions, when by bringing the arms together the rings will be closed upon the line and the card held between the arm portions, as indicated in dotted lines in Fig. l.

The device may be made of any suitable material and as fanciful in design as desired.

What I claim as new is l. A device for the purpose described, consist-ing of two portions pivotally connected IOO together and each extending upon one side of the pivot and upon the other side of the pivot shaped into a broken ring, substantially as specied.

2. In a device for the purpose described, consisting of two portions pivotally connected together and extending upon one side of the pivot and upon the other side of the pivot shaped into a. broken ring provided with oppositely-projecting teats at the end thereof, substantially as specified.

3. The tool described,consisting of twoparts pivotztlly connected together and each part E. W. SMITH, H. H. MUNGER.
