NIPPERS AND SIMILAR TOOL.

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be itknown that 1, WILLIAM A. BERNARD, of the city and county of New Haven and State of Connecticut, have invented new and useful Improvements in Nippers and Similar Tools, of which the following is a full, clear, and exact description when taken in connection with the accompanying drawings.

This invention'relates to nippers, and more particularly to that class known as end nippers, in which the cutting edge extends at right angles to the plane of the tool.

The invention has for its object, the production of a tool of this character, formed of sheet metal bent up into shape, and is shown applied to a tool formed of two parts, wherein one jaw and one handle are formed integral from. a single blank of sheet metal.

To this end, the invention consists of the several improvements and combinations of parts set forth and claimed hereinafter.

Referring to the drawings, Figure 1 represents a side elevation of a tool embodying the invention, Figs. 2 and 3, top and end views, respectively, of the same, Fig. 4, a longitudinal central vertical section through the tool, Fig. 5, a top view of one part of the tool, Fig. 6, a transverse vertical section on line 6-6 of Fig. 5, and Fig. 7, a view of the blank from which the part is formed.

In all figures, similar letters of reference represent like parts. I

The parts designated by the letters A and B represent the handle levers or gripping portions of the tool, and C and D, the jaws formed integral with the respective handles A and B. The handle portions, as shown more particularly in Figs. 2 and 4, are provided at their forward ends with parallel forwardly projecting plates E and F, through which the fulcrum pin G extends. At the forward ends of the plates E and F, the jaws C and D are formed, as hereinafter described.

The blank H is stamped out to substantially the iorm shown in Fig. 7, having a slot or mortise I. The blank is then brought to a form substantially U shaped in cross section wherein the parts .I are brought parallel to each other to form the parallel plates E or F. The lateral edges K of the rear or gripping portion are then brought together, as more particularly shown in Figs.

2 and 5, to form a smooth surface on the outer as well as the under side of the gripping portion of the handle. The forward end of the blank H is doubled on substantially the lines L and M, the part N forming the jaw C or D, with its cutting edge 0. The triangular pieces P between the lines L and M form the back of the outer ends of the jaws, as shown more particularly in Fig. 6. By this construction, the line of meeting of the lateral edges of the portion of the blank forming the gripping surfaces of the handles is on the outer side of the tool, and the jaw or cutting portion of the tool is formed by bending the forward end of the blank at right angles with the plane of the tool. By this construction, an cflicient tool is constructed, of few parts, in a very simple manner, and the parts are easily assembled by merely widening the mortise between the plates F, so as to admit the insertion of the handle A, (Figs. 1. and 2) and inserting the fulcrum pin G through the plates E and F.

Having now described my invention, what I claim and desire to secure by Letters Patent, is:

l. Nippers, or similar tools, comprising two hollow sheet metal handle levers, pivoted together, and having at their forward ends transversely extending integral cutting edges, substantially as described.

2. Nipper-s, or similar tools, comprising two hollow sheet metal handle levers, having at their forward ends parallel extending plates pivoted together, and transversely extending cutting jaws integral with said plates, substantially as described. 75

3. In nippers, or similar tools, the combination with handle levers; of jaws at their forward ends formed of sheet metal partially doubled on itself, and having cutting edges at right angles to the line of the tool, substantially as described.

4. In nippers, or similar tools, the combination with handle levers; of jaws at the forward ends formed of sheet metal partially doubled on itself, and bent backward to form substantially parallel attaching plates, substantially as described.

5. In nippers, pliers, or similar tools, the combination with handle levers, having at their forward ends jaws connected therewith, the gripping portion of said levers being formed of sheet metal, having its lateral edges bent to meet on a substantially longitudinal line on the outer 90 side of said gripping surfaces, said gripping portions being curved longitudinally, substantially as described.

In witness whereof, I have hereunto set my hand on the 20th day of March, 1907.

JOHN .W. Bnrs'ron, SAMUEL H. FISHER.
