Manufactured by Utilitool Company - Chicago IL

The tool combines jaw segments with two different jaw styles with handles that can be rotated so that either pair of jaws can be used. The handle ends can be formed as conventional screwdriver and tack claw. Versions of the patent were granted in several countries. British patent 27,540 of 1913 (GB-191327540) granted to Wernimont and William Rauen provides some insight into early production, with Wernimont and Rauen forming the Wernimont-Rauen Co. at Chicago. Some marketed as UTILITOOL from Jefferson, WI or Chicago (Utilitool showed a Chicago address in the early 1920s) -- some produced by Utility Tool Company of Chicago. Improved by patent no. 1,514,488, which adds supplemental supporting structure to the connection between the jaw and handle pieces.

Assigned to United Screw & Bolt Corp. - Chicago, Cook County IL

This patent is for Clutch Head screws that were used on General Motors vehicles from the 1940's to the 1960's. Abstract: This invention relates to screws such as wood screws, machine screws, or the like and its purpose is to provide a novel head for a screw whereby the screw may be more readily and securely driven into place equally well with a hand or power driven screw driver or wrench. As manufactured today screws adapted to be driven with a screw driver are provided with a central slot to receive the end of the screw driver. The use of slotted head screws requires that the axes of the screw and the screwdriver must be substantially coincident with the 16 driving faces of the screw driver blade substantially in line with slot to admit proper locating of the screw driver blade in the screw slot. To properly locate a screw driver in the screw slot sometimes proves to be not only a very annoying but also a costly operation; especially if screw head is in an inverted position or in a position otherwise difficult of access. In slotted heads the tendency of the 26screw driver is to work out of the slot due to the wedging action of the tapered sides of the screw driver against the side walls of the slot. This is particularly true of round head screws. It is further difficult to retain a screw driver within the slot after being located therein since the screw driver not only tends to work outwardly in a direction parallel to the axis of the screw but also laterally in a direction perpendicular to the axis of the screw. Failure to locate, and failure to 36 keep blade in proper engagement frequently results in badly distorted slots which are thereby made useless, or at least far less effective for further use, even with a well- proportioned, well-made screw driver, and not infrequently presents a serious safety hazard. Claim: A screw comprising a threaded shank and a head thereon, said head having recesses therein surrounded by a wall, said recesses being of substantial and uniform depth and having a pair of tapered teeth therebetween extending from diametrically opposite sides of the head toward the center there-of, the angle between the side walls of the teeth being ninety degrees.
