2 Claims.

This invention relates to fixtures or appliances adapted to be attached to work-benches and is particularly directed to a bench anvil or block.

It is an object of this invention to provide a fixture of this nature which is readily attachable to a work-bench and which is of heavy cast construction for providing a sturdy anchorage in bending operations. The fixture is adaptable for anchoring bars or" various shapes, such as square, rectangular, or round stock, and addl tionally includes equipment or means for punching apertures in metal or the like.

It is another object to provide an improvement over the various devices which have been used for anchoring the ends of metal to be bent, such as Vises, clamps, etc., wherein the device of the present invention includes an horage sockets in a heavy solid body contoured to provide forms upon which any particular curvature or radius may be given to the object being bent. To this end the device provides sockets having their openings flared to include the curvature desired in the bend of material.

It is another object of the invention to provide a bench-block having punch openings in its upper surface, in which block a cored cavity is included for receiving the punchings and a clearing opening extended from the cavity for re moving the punchings.

It is a further object to include, at the edge of the anvil, a means for bending over the corner of a piece of sheet metal.

Other objects and certain advantages will be more fully apparent from the description of the accompanying drawing in which:

Figure l is a perspective view showing the appliance or fixture applied to a work-bench.

Fig. 2 is a sectional view taken on line 22, Fig. 1, detailing the punch holes and the aperture for bending rectangular metal stock or bars.

Fig. 3 is a sectional view taken on line 33, Fig. 1, illustrating a socket for anchoring a square metal bar permitting the accomplishment of various types of work upon the anchored bar.

Fig. 4 is a top plan view of the appliance or fixture.

The device is formed of a cast or forged metal body 5 cored to reduce the weight of the body at those points where strength is not required. This body is substantially rectangular in outline and of considerable thickness. The sides are undercut as at 6 to provide a base flange which does not extend beyond the general outline of the block or cast body. At each corner 930. Serial No. 471,848 (Cl. 153-32) of the formed flange, an attaching device such as a bolt may be applied through apertures 7 in the flange.

The undercutting is irregular at one side of the block, namely, the forward side or the side disposed toward the workman. This side of the block includes two portions 8, 9 which are not undercut but present straight flush sides. Extending inwardly through the portion 8, a rectangular socket 10 is formed (see Fig. 2). The socket 10 is rounded at its outer end as at 10a for the purpose of bending the metal bar, inserted in the socket, on a corresponding radius.

The socket 11 formed in the other portion 9 also extends directly laterally into the side but is of circular shape and includes a flared opening formed by rounding one side of the socket, as at li the curve uniformly terminating in the outer face of the side wall of the anvil in the same manner as the socket 10. These sockets may be of any desired form such as square, rectangular or circular and the curvature at the mouth of the socket may be generated on any desired radius depending upon the curvature desired at the bend of the metal bar.

For the purpose of holding a square bar of metal, a socket 12 is formed downwardly in the upper face of the anvil, this socket being rounded similar to the others as at 12. The socket 12 may be used for anchoring a square bar firmly in place while a bending operation is being performed upon the bar in the same manner as the horizontal sockets extending into the side of the anvil. These described sockets function efficiently for supporting the bars while various other types of work are being performed.

The block is further provided with a series of punch holes 13 extending downwardly in its face and opening into a cored cavity 14 in the block. Any number of apertures of any size may be provided at this point for punching apertures in sheet metal. The cored region of the block is provided with an exit which is in the form of a slot 15 cut through the lower portion of the rear side of the block. This provides a means for removing the punchings dropped through the punch holes into the cavity.

A longitudinal slot 16 is formed in the base of the anvil extending the entire length thereof and adapted to engage over a bench rail for rigidly attaching the block or anchor in position. The block or anvil provides a flat top surface upon which surface sheet-metal may be placed and punched, and has one corner 17 chamfered to enable the workman to turn the corners of metal laid upon the top surface.

The Workman can rapidly apply the work to the block and it is securely held by the heavy block While he periorms various operations.

Having described my invention, I claim:

1. A new article of manufacture comprising a one-piece metal block of rectangular form, said block having a flat full dimension wcrl; ing top surface and including a cored. interior, said top including a series of punch holes entering into said cored interior, and said interior including a clean-out opening for removing punchings, said block having its sides partially undercut to provide an attachment flange, the portion of the sides not undercut adapted to include a series of socket holes having mouths of varying contours for bending pipe on various radii.

2. A new article of manufacture comprising a one-piece metal block of rectangular form, said block having a flat full dimension working top surface and including a cored interior, the sides of said rectangular block being partially undercut to provide attaching flanges at the base of said block, the portions of said sides not underout including socket holes, the mouths of which have varying contours for bending pipe on various radii, the top of said block adapted to include punch-holes, and the cored interior adapted to receive the punchings.

ALBERT T. HARLAND.
