UNITED STATES PATENT OFFICE.

ANTON SOHUERMANN, OF DFOATUR, ILLINOIS.

SHEARS FOR USE IN VISES.

SPECIFICATION forming part of Letters Patent No. 613,322, dated November 1, 1898. Application filed August 8, 1898. $erial No. 688,062. (No model.)

To all whom it may concern: 7

Be it known that I, ANTON SGHUERMANN, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Shears for Use in Vises, of which the following is aspecification.

This invention is intended to provide shears that may be used in an ordinary vise to cut metal of moderate thickness. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

The shears is embodied in a pair of frames hinged together and provided with shear-jaws in their swinging ends. The cutting edges of the jaws converge toward each other at one side of the shears, and they swing in curvilinear surfaces concentric with and parallel to the pivot-axis of the frames. One of the frames is longer than the other, so that one shear-jaw may overlap the other, and both are cut away or forked at their hinged ends to fit over the screw of the vise with which theyareconnected. Theframeshavesprings that tend to separate the jaws, and they also have stops to prevent the jaws from opening needlessly wide. Depressions are formed in the outside surfaces of the frames at the swinging ends thereof to receive thejaws of the vise.

In the drawings forming part of this specification, Figure 1 is a central section through the shears on line a: in Fig. 2. Fig. 2 is an elevation of the shears. Fig. 3 is an end view or plan of the same.

One shear-jaw is shown at 6 and the other at 8. The legs of jaw 6 are shown at 1, and those of jaw 8 are shown at 2. The legs are hinged together at 3. Stops 4 preventthe jaws from opening needlessly wide, and a spring or springs, as 5, tends to hold the jaws open. The legs of jaw 6 are shorter than those of jaw 8, so that jaw 8 overlaps jaw 6 in operation. Jaw 6 has a fixed cutter-blade 7 in its upper inner edge, and jaw 8 has an adjustable cutter-blade 9 in its lower inner edge. The frames, including the jaws, are preferably made of malleable iron, and the cutterblades are made of steel. The cutter-blade 7 is fixed to the jaw 6 by screws or the like, while blade 9 is fastened in its jaw in a man- 5o'ner permitting adjustment toward and from blade 7. The means employed to adjust blade 9 comprise a set of adjusting-screws 10 set in jaw 8 with their inner ends pointed toward the hinge of the frames and bearing against the outer surface of the cutter-blade, and the transverse binding-screws 11 aid in holding the blade in any desired position. The binding-screws are screwed into the blade, and they extend through slots in jaw 8 at right angles to blade 9. The slots give play to the screws toward and from the hinge of the frames, and when such screws are loosened the cutter-blade may be readily ad justed to cooperate accurately with the relatively-fixed blade 7. Thelegs of the frames are curved more or less to suit difierent conditions and requirements, and there is no restriction in this regard. Seats, as 12, are formed in the frames to receive the jaws of the vise, and such seats provide against downward motion of the shears in the vise through force of gravity and sidewise motion of the shears in the vise through the operation of the shears. The upper ledges of the seats sustain the shears against gravity, and the side ledges sustain it against motion that might otherwise result from pressure of the shear-jaws against the metal to be cut or from pressure of the metal against the jaws in a sidewise direction.

In operation the shears is placed between the jaws of a vise, as suggested in Fig. 1, where the jaws of a vise are shown in dotted lines at cc and y. The metal is placed between the open jaws, and the vise is screwed up in the usual manner until the metal is cut. The hinges 3 hold the cutter-blades accurately and firmly in alinement one with the other, and the convergence of the blades gives the shear motion, whereby the point of cutting action travels from one side of the shears to the other.

I The shears is cheap, simple, and easily manipulated. It Will do the work of much larger and more pretentious shears, and it is particularly convenient for an occasional job of shearing.

What I claim is- 1. A shears for use in vises, comprising a pair of frames hinged togetherand having seats for the jaws of a vise, and shear-jaws in the swinging ends of the frames disposed approximately parallel with the hinge-axis of the frames.

2. A shears for use in vises, comprising a pair of frames hinged together and having seats for the jaws of a vise, and shear-jaws set convergently in the swinging ends of the frames and disposed approximately parallel with the hinge, whereby the shear-jaws swing in surfaces concentric with the hinge-axis of the frames and the point of cutting action moves from one side of the shears t0 the other.

3. A shears for use in Vises, comprising a pair of frames hinged together and having seats for the jaws of a vise, a stop to prevent extreme separation of the swinging ends of the frames, a spring tending to force the swinging ends apart, and shear-jaws in the swinging ends of the frames disposed approximately parallel With the hinge-axis of the frames.

In testimony whereof I sign my name in the presence of two subscribing witnesses. ANTON SOIIUERMANN. lVit-nesses:

W. H. ELWOOD, W. E. ADAMS.
