A TTOR/VEK Patented July 7, 1942 UNITED STATES PATENT OFFICE VISE CUTTER George M. Ernst, Edgewater, 0010.

Application January 17, 1941, Serial No. 374,903

2 Claims.

This invention relates to a cutting attachment for adapting an ordinary bench vise to a cutter for cutting metallic rods, bars, etc., and has for its principal object the provision of an economical and highly efiicient device which can be quickly and easily adapted to fit the jaws of any given vise; which can be instantly put in place thereon when needed; and which will quickly and easily cut metallic material by the simple operation of rotating the vise screw.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efliciency. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective view illustrating the improved attachment in place on a typical bench vise;

Fig. 2 is a face view of one of the attachment members illustrating it as furnished to the user and before being fitted to the vise;

Fig. 3 is a plan view thereof; and

Fig. 4 is a longitudinal section, taken on the line 4-l, Fig. 2.

In the drawing, the fixed jaw of a typical Vise is illustrated at H), the movable jaw thereof at H, and the handle for rotating the vise screw at I2.

The improved cutting attachment consists of two similar devices, one being applied to each of the vise jaws l and H. Each of the devices consists of three parts, a metallic strap l3, an angle plate I4, and acutting knife IS.

The strap I3 is of sufficient length to allow its extremities to be bent back over the ends of the widest expected vise jaw, as indicated at It in Fig. 1. The angle plate is shaped to extend vertically across the strap l3 thence backwardly over the top of the vise jaw. The angle plate is secured to the strap by means of cars H which are formed in the strap. The cars extend through suitable openings in the angle plate and are turned inwardly against the face of the latter to clamp the same rigidly in place.

The knife [5 has a T-shaped cross section to provide a flat base having oppositely projecting side flanges l8. The knife projects through a vertical slot in the angle plate I4 and the angle plate is formed with overlapping portions which lie over the flanges 18 to hold the knife in place. The knife cannot be moved upwardly or downwardly due to the limiting confines in the slot in the angle plate 14 and cannot be moved sidewardly due to the engagement of the overlapping portions 19.

The devices are furnished to the user in the condition shown in Figs. 2, 3, and 4. The user places the angle plate over the middle of the vise jaw and then bends the ends of the strap around the ends of the vise jaw, being careful to maintain the two plates in alignment with each other. No further adjustment is required. When not in use, the device can be simply lifted from the vise jaw. When desired for use, they can be simply slipped thereon.

For cutting bar stock the latter is placed between the two opposing knives of the device and the vise screw handle I2 is rotated to cause the jaw l l to approach the jaw 10. This forces the two knives into the bar. This forcing can be continued until the entire bar is severed or the bar can be indented sufficiently on all Sides to allow it to be broken to form a more regular fracture.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

A cutting attachment for vise jaws comprising: two similar cutter members each consisting of a horizontal strap extending across the face of a vise jaw; rearwardly turned extremities on said strap engaging the ends of a vise jaw; an angle member extending upwardly across the face of said strap and rearwardly over said vise jaw; a vertical knife member having a T- shaped cross section to provide two oppositely extending side flanges, said knife member extending through an opening in said angle member and projecting beyond the face of said strap; means for securing said angle member to said strap; and said side flanges projecting between said angle member and said strap to hold said knife member in place.

2. A cutting attachment for vise jaws comprising: two attachment members, each of said attachment members including a strap; means for supporting said strap horizontally across the face of a vise jaw; a knife member extending vertically of said strap, said knife member having a T-shaped cross section to provide two uppositely extending base flanges; an angle member extending upwardly over the face of said strap and rearwardly over said vise jaw and provided with openings in its vertical portion, said knife member extending through one of said openings with its base flanges contacting the rear face of said angle member; and tongues formed. on said strap and extending through the remaining openings said tongues being bent over the face of said angle member to clamp said base flanges between said strap and. said angle member.
