WILLIAM H. WOOD, OF CLEVELAND, OHIO, ASSIGNOR T0 STANLEY W. COOK, TRUSTEE, OF CHICAGO, ILLINOIS.

METAL-WORKING- WORK-I-IOLDING' ANVIL.

Z i; .ff/7 w71 om t may concern.

Be it known that I, VILLIAM H. lVooD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Metal-forking fork-Holding Anvils, of which the following is a specification.

My invention relates to improvements in metal working, work-holding anvils, and has for its particular object to provide a simple, inexpensive and satisfactory appliance for employment in forming metallic arch-support-plates to conform with humanfoot curvatures.

The single or plural metallic plates of arch supports are usually machine-shaped, in course of manufacture, in compound curvatures that, in the assembled device, give an approximation of average curvatures of the under surface of the human foot, but in the fitting of arch supports to individuals, the curvatures often must be altered, and this may be done by pounding the plate with a hammer upon a suitable anvil.

In my anvil construction herein shown and claimed I provide a simple and inexpensive device facilitating this plate-forming-operation, and in the drawings, wherein I have illustrated a particular embodiment of my invention- Figure 1 is a perspective view thereof;

Fig. 2 is a longitudinal vertical section; and

Fig. 3 is a transverse vertical section on line 3 3 of Fig. 2.

10 indicates the metal anvil body that usually is secured to a suitable table 11 as by bolts 12 extending through anchorage ears 13 of the body, said body being in general of oblong shape, traversed, approximately centrally, by a recess 14, that preferably tapers transversely of the plate and that has communicating therewith a longitudinally-extending recess or bay 15. By shifting the approximately-pre-formed archplate to bring any suitable portion over the recess 14 or the bay 15 a peeninghammer (suggested in dotted lines at I-I) may be employed properly to re-form the curvature. The bay 15 is especially advantageous in facilitating the formation of a hump or node in the anterior portion of an arch support plate for purposes well understood by arch support fitters.

Specification of Letters Patent.

' Application led December 16, 1916.

Patented oet. 1c, i917.

Serial No. 137,323.

To one side of the body 10, preferably adjacent to the vertical plane of the axial line of the recess 14:, I attach the flexible workholding strap 20, that is preferably made of leather, that has a narrow fast end pivotally secured, as on a suitably washered screw or pin 22 extending into the body of the anvil, and that has a prolonged narrow loose end or finger piece 23 adapted to be passed under the transverse guide-bar of a staple-formed guide 24', secured in the side of the anvil body opposite to the pivotal fastener 22. Between said narrow portions I provide a broad mid-portion or cover-part 24 adapted to overlie the anvil and the arch support to be placed thereon, this broad cover-part providing at one side the offset portion 24a to extend over one edge of the recess 14C and at its other side the extension tab 24h to overlie the bay 15 in the anvil. In use, the' arch support (suggested in dotted lines at A) is laid on the anvil, to bring the portion that is to be bent into appropriate relation to a suitably shaped portion of the anvil, and then the strap, thrown over the positioned arch support, has its linger piece 23 passed under the staple 24, and is pulled taut and firmly held by the operator with one hand, while he peens the metal arch support plate with the other hand, the broad enlargement or cover-part of the strap affording a protective cover whereon the hammer blows impinge, so that the surface of the metal may not be scarred.

While I have herein described in some detail this specic embodiment of my invention it will be apparent that changes in detail of construction and arrangement may be made without departure from the spirit of my invention and within the scope of the appended claims.

Having described my invention, what I claim is:

1. An anvil of the character described providing a body having a concaved recess and bay, a holding strap secured to one side of said body, adapted to overlie the body and the article placed thereon, and a guide for the free extremity of said strap positioned on the other side of the anvil body.

Q. In a device of the character described, the combination of an anvil body having' a recess and bay, of a strap connected with one side of the body for extension of its free end across the recessed portion of the body and down the other side thereof, the loose end of the strap constituting a linger grip portion, a guide on said other side of the anvil body to receive the loose end of the strap, said strap having a broad intermediate portion to overlie the recess and bay.

3. As anV article of manufacture an anvil having in its top a recess and bay, said anvil carrying a fastening device and a guide on opposite sides of said body in line with said recess, a strap having its fast end secured by said fastening means and having its loose end adapted to pass under the guide, said Copiesy of this patent may be obtained for strap having a broadened portion to overlie the recess.

4. As an article of manufacture'an anvilv comprising a body lO having in its top a recess 14 and bayl l5, a strap 20 pivoted to one side of thev body, having a broadenedl portion 24: to overlie the recess and a tab 2LP to overlie the bay, the strap being narrow,

Y at its loose end,-and a guide 24 to receive the WI'LLIAM- H. WOOD.
