SAMUEL P. STRAHAN, OF KANSAS CITY, MISSOURI, ASSIGNOR '10 HENDRICKS P. STRAHAN, OF KANSAS CITY, MISSOURI.

ANVIL ATTACHMENT.

Application filed March 28, 1917.

To all whom it may concern:

Be it known that I, SAMUEL P. STRAHAN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Anvil Attachments, of which the following is a specification.

My invention relates to an attachment for anvils.

Blacksmiths usually bend heated metal like rods and bars with the aid of a vise, but in carrying out such method find it difficult and usually impossible to heat the metal to such a degree of temperature that it will effectively retain its heat during transfer from the forge to the vise as an appreciable amount of time is lost in the operation. My

invention aims to overcome this difficulty,

and to that end aims to provide a means whereby the heated metal or work may be readily held against an anvil and brought into the proper or desired shape.

Further it is an object to provide means to accomplish the end stated consisting of a clamp lever attachable to an anvil and movable relatively thereto; to provide such a clamp lever having means whereby it may be detachably connected to an anvil at the heel, and to provide a clamp lever having an angularly disposed portion through which the anvil heel projects and having a lug to enter an opening of the anvil to prevent movement of the lever longitudinally of the anvil.

lVith the above and additional objects, such as will become apparent, as the description 'of the invention hereinafter progrosses, one preferred embodiment has been devised and illustrated in accompanying drawings wherein Figure 1 is a top or plan view of an anvil having my improvements associated therewith;

Fig. 2 is a side elevation, partly in section, of the parts of Fig. 1, and

Fig. 3 is a perspective view of the attachment alone.

Referring specifically to the drawings, wherein like reference characters designate like or similar parts, an anvil has been conventionally shown at 4: of which 5 is the heel and 6 the usual square opening provided therethrough.

With relation to the attachment, it com- Specification of Letters Patent.

Serial No. 158,024.

prises an elongated relatively wide lever or clamping member 7 from one end of which extends integrally, an angularly disposed frame 8 providing an opening 9. Also depending integrally from the plate 7 and substantially at a right angle thereto at the junction of the frame therewith is a lug 10. A shank 11 is formed at the opposite end of the clamp members, and thereon a handle 12 in the form of a sleeve is slidably mounted. Movement of the handle 12 on the shank 11, however, is limited, in view of the fact that a pin or lug 13 extends laterally from the shank 11 and is disposed within an elongated slot 14 of the handle.

In use the attachment is applied to the anvil in such a manner that the heel 5 extends through opening 9 loosely and lug 10 extends into the opening 6 loosely so that the plate or clamp member 7 may be swung in a vertical plane from the heel 5 as a fulcrum. The lug l0 prevents undue movement of the lever or clamp member 7 longitudinally of the anvil. The heated rods, bars or other work are adapted to be disposed intermediate the clamp member 7 and the anvil top and by means of manual manipulation of handle 12 be securely clamped to the anvil. One blacksmith or workman may shape the work by the use of a suitable tool like a sledge hammer and another blacksmith or workman may maintain the handle 12 depressed and the work securely clamped to the anvil. The handle 12 is extensible to permit its operator to move the same to different positions according to his objection to the heat from the work.

I do not limit myself to any particular material from which the attachment may be made but it is preferably constructed from untempered tool steel in order that it may be as stiff as possible and danger of fracture from jars received from sledge hammers or other tools may be minimized.

The details of construction may be varied without departing from the spirit and scope of the invention provided they fall within the spirit and scope of appended claims.

I claim:

1. A device of the class described having a clamping member, means extending at an obtuse angle therefrom provided with an opening therethrough for attachment to a support as set forth, and a lug extending 10 means extending laterally from said member at the junction of the angularly disposed means therewith, adapted to engage the upper part of said opening to prevent undue movement thereof. 7

In testimony whereof I affix my signature 15 in presence of two witnesses.

SAMUEL P. STRAHAN.
