May 23, 1933. MLT. CLARK CIRCULAR GRIP PLIERS Filed Sept. 28, 1932 llomey Patented May 23, 1933 UNITED STATES MAJORTAYLOR CLARK, F. ELHsFoRD, NEW vom:

CIRCULAR GRIP PL'IEns Application filed September 28, 1932. y SerialvNo. 635,253.

This invention relates to pliers which are mainly designed for removing bulbs from electric light sockets but which of course can be used for other purposes, the general object of the invention being to provide the pliers with jaws of substantially semi-circular shape in cross section and having teeth on their inner surfaces for gripping the base of the bulb so that the bulb can be removed easily and quickl and withoutv danger' of breaking the bul which often results in injury to the operators hands.

This invention also consists lih certain other features of construction` and inthe combination and arrangement of the several parts to be hereinafter fully described, illustrated in theaccompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawing wherein ylike characters denote like or corresponding parts throughout the several views, and in which i Figurel is an elevation of the improved pliers.

Fig. 2 a section on line 2-2 of Fig. 1.

Fig. 3 is an end view of one of the jaws showing hcw it is attached to a part of the pliers.

Fig. 4 is a sectional view showing how the pliers are used to remove an electric light bulb.

As shown inthese views, the pliers comprises a pair of kmembers l and 2 which are pivotally connected together intermediate their ends as shown at 3-with a spring 4 having a part coiled around the pivot with its ends engaging the handle parts of the members l and 2 for normally holding the jaw .carrying parts separated, as shown in Fig. l.

As shown in these figures, the members l and 2 are preferably of channel-shape in cross section. Each jaw carrying part of the members l and 2 is of slightly curved construction as shown inFig. 1 with its end provided with a curved part 5 on its inner face which forms a seat for the semi-circular jaw 6, said jaw being fastened to the seat forming part by the rivets 7, or otherwise,as shown 1n Fig. 3.

Each jaw has teeth 8 on its inner surface and when the pliers are closed the jaws form a substantially circular gripping part 515 for engaging an object such as thebase of a bulb B in Fig. 4 whereby the bulb can be easily removed from the socket A in Fig. 4 without danger of breaking the bulb or damaging the parts of the socket. Each jaw e@ is eXteriorly flared or tapered as shown at 9 so that the jaws can readily grip a part of the base of thebulb by entering the flaring part of the porcelain portion of the socket, as shown in F ig.'4. 65

As shown in Fig. 2, the jaws extend lengthwise at right angles from the members l and 2 of the pliers and the teeth carrying part of each jaw is thickened so that the thin portion will not contact the bulb as 7@ shown in Fig. 4.'

'Thus it will be seen that I have provided vsimple means including semi-circular jaw members for removing bulbs from their sockets without danger of breaking the bulbs or injuring the parts of the sockets.

It is thought from the foregoing description that the radvantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be e" made in the construction and in the combination of and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having thusdescribedmy invention, what I claim as new is A device of the class described 'comprising a pair of members pivotally connected together intermediate their ends and each including a handle part and a aw carrying part, the free end` portion of each aw carrying part having its inner face of concave shape, a pair of substantially semi-circular jaws of considerable length and extending at right angles to said jaw carrying parts, each jaw having a part of its convex face fastened in the concavity of a jaw carrying part, with one end of a jaw Hush with one face of the j aw carrying part and the other end projecting beyond the other face of said jaw carrying part, said projecting portion of the jaw being exteriorly tapered and said jaw having a thickened portion extending from the outer end of the projecting portion to a point an appreciable distance from that end of the jaw Which is iush with one 'face of the jaw carrying part, said thickened portion being located on the inner face of the aW and longitudinally extending teeth on said thickened portion.

In testimony whereof I aflix my signature.

MAJOR TAYLOR CLARK.
