Application October 3 1947, Serial No. 777,659

1 Claim. 1

The present invention relates to certain new and useful improvements in novel tongs which are especially, but not necessarily, useful on a welders bench to expedite the step of holding various sizes and types of work pieces for welding and other purposes.

An object of the invention is to structurally, functionally and otherwise improve upon plierlike tongs, in that same are provided with long, conveniently usable handles and correspondingly long coacting jaws, said jaws being especially shaped to enable the user to attain the desired ends with speed and reliability.

More specifically, novelty is predicated upon elongated handles and jaws coacting in enabling work pieces to be securely held when the handles are close together, whereby to permit the tongs and work to be held in one hand, while performingattending tasks with the other hand.

Other objects and advantages will become more readily apparent from the following description and the accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a perspective view of a pair of bench tongs constructed in accordance with the principles of this invention, showing the handles and jaws closed.

Figures 2 and 3 are enlarged cross-sectional views, taken on the planes of the lines 2-2 and 33, respectively, of Figure 1, looking in the direction of the arrows.

Referring now to the drawings by distinguishing references, the elongated

straight handles

5 and 6 are flattened and crossed, as at the points 1 and 8, where they are pivotally joined, as at 9, in pliers-like fashion. The offset lower jaw l 0 is rectilinearly straight from end-to-end and the work-gripping surface is flat, as at H. The tip is shaped, as indicated at [2, to cooperate with a correspondingly shaped tip I3 on the coacting upper jaw I 4. The surface of the tip I 3 is also flat, as at l5, and therefore, the two tip portions I 2 and I3 come close together for gripping fine gauge work parts, such as thin metal sheets and the like. The remainder of the upper jaw is provided with a compound bend formation and the bends I6 and I! define curvate gripping surfaces l8 and 19, respectively. The curvatures of the faces and bends are such that the surface l8 coacts with the jaw ID for gripping small rods and pipes, while the surface l9 coacts with the same jaw to satisfactorily grip and hold pipes and rods of larger diameter.

It is obvious that the curvature and dimensions of said bends may be varied to handle different types of work and job performance. In fact, a single elongated bend might, if desired, be within the purview of the invention.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

Having described the invention what is claimed as new is:

Welders bench tongs adapted to grip a piece of work in such a way that the welder may grasp and hold the tongs and work in one hand with the other hand free to perform other activities, comprising a pair of crossed linearly straight handles, the crossed portions of said handles being pivotally connected together and the portions outwardly of the pivotal connection constituting work grasping and holding jaws, one jaw being of appreciable length and having an uninterrupted straight edged work basing and clamping surface, said surface being in a plane which is paral lel with the plane of said handles, the remaining jaw having a straight elongated terminal portion at its outer end adapted to firmly contact the corresponding end of said work basing surface, said remaining jaw including progressively enlarged transverse longitudinally spaced bends, the crotch portions of said bends being laterally spaced from said work basing surface and said bends being adapted to embrace major portions of the work in order that the latter may be pressed and held against said work surface, each handle and its companion jaw being of one-piece construction.
