Application filed July l0, 1922. Serial No. 573,771.

provements in Tweezers, of which the following is a specification.

This invention relates to tools of the tweezers type, and its object is to produce a tool of this kind which is very simple in construction, and therefore capable of being easily and cheaply manufactured.

The invention also has for its vobject to provide a. tool of the kind stated which will firmly and vautomatically hold the object grasped thereby.

Wth the objects stated in view, the invention consists in a novel combination vand arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing, wherein:

Figure l is a perspective view of the tool; Fig. 2 is a section on the line 2 2 of Fig.A l. Fig. 3 is al view similar to Fig. l showing a modification, and Fig. l is a section on the line 4 4 of Fig. 3.V

Referring specifically to the drawing, the

tool is constructed of a single strip ofV 0 spring metal which is bent intermediate its ends to form two spring arms 10, the free end portions ll of which are the jaws of the tool. The arms lO are laterally spaced and near the end portions l1 they are brought together and loosely connected. The. connection, as shown in Figs. 1 and 2, is a rivet consisting of a shank l2 and heads i3. Forwardly of this rivet, the end portions il are bowed outwardly7 or away from each other, with their extremities or tips coming together.

The arms 10,Y due to their inherent resil-A iency, have a normal tendency7 to spread, which, owing to the connection between the end portions 1l thereof, keeps the extremities thereof in contact, and hence the'jaws formed by said end portions are normally closed. To open the jaws, it is necessary only to press together the arms 10 some dis tance back of the connection. This action causes the jaws to spread or open up as shown dotted in Fig. 2, to grasp the object to be held, and upon releasing the arms l0, they automatically spread and cause the jaws to close up and firmly grip to object.l

In order that the rivet heads 13 may not interfere with this movement of the arms l0 and the jaw portions ll, said heads have their surfaces'which are next to the arms and jaw portions beveled in opposite directions, as shown in Fig. 2.

Figs. 3 and 4f show a different connection between the arms lO. Here, a sleeve' lll is employed which envelops the arms,`and is flared from a point midway between its ends inthe direction of each end, to permit the Ahereinbefore play of the arms and the jaw portions thereof.

The loop l5 connecting thearms l0 enables the tool to be hung on ones finger with an object in its grasp, so as to be handy for the work in progress.

I claim:

l. A gripping tool comprising connected y spring arms, the forward portions of which are curved inwardly to define opposed rounded contact surfaces, the portions of said arms in advance of said opposed rounded contact surfaces being bowedv and having' their YeXtren/iities normally in contact, and means connecting the arms at the said inwardly curved forward end portionsy of the same, whereby the said rounded contact surfaces are maintained flatly in en-l gagement with veach other. I

2. A gripping tool comprising connected spring arrrs, the forward portions of which are curved inwardly to define opposed rounded contact surfaces, the portions of said Y Aarms in advance of said opposed rounded contact surfaces being bowed and having their extremities normally in contact, and a pinextending through and loosely connecting the arms at the said inwardly curved forward end portions of the same and having heads, the inner sides of which are rounded to conform to the curvaturev of the adjacent portions of said arms.

3. A gripping tool comprising connected spring arms, the forward portions of which are bowed inwardly to define opposed rounded contact surfaces, the portions of said arms' in advance of said kopposed rounded contact surfaces being bowed outwardly and having their forward extremities normally in contact. e

In testimony whereof l affix my signature. Y
