ANVIL ATTACHMENT.

SPECIFICATION forming part of Letters iatent'No. 610,137, dated August so, 1898.

- Application filed February 23, 1898.1 Serial No. 671,807. (l lo model.)

To all whom it may concern:

Be it known that I, JAMES A. GUILES, a citizen of the United States, residing at Hadley, in the county of LapeerandState of Michigan,

have invented an ew and useful Anvil Attachmen t, of whichthe following is a specification.

This invention provides a device for use in connection with anvils to lessen the labor of blacksmiths and to enable them to dispense with a helper when sharpening or forming calks upon horseshoes, the means being of such construction as to be applied to an anvil without requiring the boring thereof or any special construction in its outline to provide for the application thereto of the device.

The attachment consists of a clamp to be fitted to the body of the anvil and having an obliquely-disposed arm projecting from one of the members of the clamp, a lever pivotally connected with the obliquely-disposed arm and adapted to cooperate with a side of the anvil toclamp the article to be operated upon and having its lower end turned, forming a treadle, upon which pressure is exerted to cause the jaw of the clamp to grip the horseshoe or other article, and a spring secured to the block of the anvil and having linked connection with the lever, so as to hold its advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure l is a rear view of an anvil, showing the invention in operative relation. Fig. 2 is a side view thereof. Fig. 3 is a perspective view of theattachment, showing the parts in operative relation and the anvil and block in dotted lines.

Corresponding and like parts are referred to in the following description andtindicated tion.

the upper end or jaw of the said lever.

in the views of the drawings by the same reference characters.

The anvil 1 and block 2 are of ordinary construction and illustrate the application of the invention which is especially designed to cooperate therewith, A clamp is applied to the reduced portion of the anvil and consists of parallel bars 3 and 4, having transversely-alining openings, and bolts 5, passing through the openings of the'bars 3and l and clamping them against the sides of the anvil, the bolts being arranged so as to engage with the ends of the anvil, and thereby prevent movement of the clamp when in proper posi- An end portion of one of the bars, as 4, is extended and bent, forming an obliquely disposed arm 6, towhich a lever 7 is ful-' crumed, the upper end of the lever forming a jaw to act jointly with a side of the anvil, so as to clamp the work. The lower end of the lever 7 is bent, and its terminal portion is expanded to provide a treadle 8, which re ceives the pressure exerted to turn the lever upon its pivotal connection with the arm 6, so as to grip the work between the anvil anjg spring 9 issecured at its lower end to the block 2 and is provided at its upper end with a hook 10, which engages with one end. of a link 11, by means of which the free end of the spring is connected with the lever 7 at a point below its pivotal connection with the arm 6. This spring 9 holds the jaw or upper end of the lever 7 away from the anvil a sufficient distance, so as not to interfere with the ordinary use of the anvil when the assistance of the attachment is not required. The relative height of the attachment can be adjusted by moving the clamp up or down, so that the upper end of the lever may come about on a level with the upper face of the anvil, thereby admitting of the attachment being applied to different makes and sizes of anvils within certain prescribed limits. The horseshoe, article, or other work to be held is gripped between the jaw of the lever 7 and the side ofthe anvil contiguous thereto, the degree of the gripping force depending upon the pressure applied to the treadle 8. Upon removing the pressure from the treadle the release the work and move the upper end of the lever away from the anvil to a safe distance, so as not to interfere with the free use of the anvil in connection with Work not re- 'quiring to be clamped thereto.

In order to adaptthe attachment for a wide range of adjustment, the bars 3 and 4 have longitudinal slots 12 at one end, through which one of the bolts 5 passes, and the lever 7 is composed of two sections adjustably connected, the contiguous or overlapping ends of the sections being longitudinally slotted, as shown at 13, and receiving bolts 14, by means of which the sections are secured when adjusted, thereby enabling the lever 7 to be lengthened or shortened to adapt it to the relative height of any anvil and its supportingblock.

Having thus described the invention,what is claimed, and desired to be secured by Letters Patent, is-

1. The herein-described attachment for anvils consisting of a clamp comprising longitudinal bars and bolts connecting the end portions of the bars and clamping them against the sides of the anvil, one of the bars having an end portion extended and bent to provide an obliquely-disposed arm, a lever fulcrumed near'its upper end to the said oblique arm and terminating in a jaw to grip the work between it and a side of the anvil, and having its lower end bent and flattened to provide a treadle, a fiat spring to be secured at one end to the anvil-block, and a link connecting the free end of the spring with the lever to hold the latter normally out of action, substantially as set forth.

2. An attachment for anvils, consisting of a clamp comprising parallel bars having longitudinal slots at one end, bolts connecting the bars, one of the bolts operating in the longitudinal slots thereof and one of the bars having an upwardly-extending arm, a lever fulcrumed to said arm and composed of sections having their end portions overlapping and longitudinally slotted, fastenings operat ing in the slots of the lever-sections and adjustably connecting them, a spring, and a link connecting the spring with the lever, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

JAMES A. GUILES. Witnesses:
