Altai 1103M UTE TAT% T QFFTQ HARDY ATTACHMENT FOR .ANVILS.

To all whom it may concern:

Be it known that we, CHRISTOPHER C. GRAY and MIKE GRAY, citizens of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Hardy Attachments for Anvlls, of which the following is a specification.

The present invention consists of a hardy attachment for anvils.

The hardy ordinarily employed in connection wit-h anvils consists of a cutting tool adapted to be placed upon the anvil by the workman, and usually a separate article entirely from the anvil. The hardy is often lost and again it is often so hot as to be difficult to handle in placing the same in position.

This invention is designed to provlde an improved means of the class in which the hardy is carried by an attachment mounted adjacent to the anvil, and is adapted to be thrown into and out of position by operation of suitable mechanism.

For a full understanding of the present invention, reference is to be had to the fol lowing description and to the accompanying drawings, in which Figure 1 is a perspective view showing an anvil and a hardy attachment embodying the invention in cooperation therewith; Fig. 2 is an end view of the anvil and support, the hardy being shown m an lnope'rative position; Fig. 3 is a deta1l fragmentary view, partly in section, showing the manner of attaching the hardy to the operatmg shaft.

Throughout the following detail descrip tion, and on the several figures of the drawings, similar parts 'are referred to by like reference characters.

Describing the invention specifically, 1 denotes the anvil which is of the ordinary type, being supported upon a base 2 of any suitable construction. The hardy or cutting tool 3 is rigidly secured to an arm 4 projecting horizontally from an angular extension 5, the latter in turn formlng an 1ntegral portion of an arm 6 projecting from a vertical shaft 7. The shaft 7 is adapted for partial rotative and vertical sliding movement upon a bracket 8, the latter having bearings 9 at its upper and lower ends to receive the shaft. At the lower extremity of the shaft 7 is formed a crank arm 10, and

a spring 11, preferably of the coil-ed type, is connected at one end to the base 2 and at the other end to the arm 10 aforesaid.

The operating device associated with the shaft 7, for actuating the latter to move the hardy 3 into an operative position, comprises a lever 12 pivoted between its ends at 13 to the support 2, a vertical operating rod 14: being connected with one end of the lever and sliding through a bracket 15 on the support 2. At its lower end, the rod 14 has a foot piece 16. A link 17 is connected at one end with the other end of the lever 12 and the opposite or lowermost end of the link is connected with the crank arm 10.

In the operation of the invention, assum ing that the parts are in the position shown in Fig. 2, when the workman desires to utilize the hardy or cutting tool 3, it is only necessary for him to depress the foot piece 1.6, and such action, through the link 17, will exercise an upward pull upon the shaft 7, raising said shaft against the tension of the spring 11 until the hardy 3 clears the upper side of the anvil whereupon the spring 11 imparts to the shaft 7 through the crank arm 10, a slight rotat-ive movement to force the hardy into a position over the central portion of the body of the anvil, as shown in Fig. 1. When the workman has finished using the hardy 3, it is only necessary for him to strike the tool a slight blow to force it laterally, said movement turning the shaft 7 until the hardy clears the upper side of the anvil, whereupon the spring 11 will, by a quick movement, pull downwardly on the shaft 7, forcing the hardy into the inoperative position shown in Fig. 2.

The spring 11, by reason of itspeculiar arrangement performs a dual function, so to speak, in that it tends to pull clownwardly upon the hardy 3 to force the same into an inoperative position, but when the shaft 7 is raised by the operation of the rod 14, the spring 11 tends to impart rotative movement to the shaft 7 to carry the hardy into its operative position on the central portion of the anvil Having thus described our invention, what is claimed as new is:

1. In combination, an anvil, a hardy attachment therefor comprising a support, a hardy carried by said support, means coacting with the support to normally hold the hardy in an inoperative position, and also tending to move said support to throw the hardy into an operative position, and an actuating device to elevate the support.

2. In combination, an anvil, a hardy attachment therefor comprising a hardy movable on and off the anvil, a vertical shaft supporting said hardy, means for moving said shaft vertically, and spring means coacting with the shaft to impart rotative movement thereto at a predetermined point in the vertical movement of the shaft to carry the hardy into an operative position on the anvil.

3. In combination, an anvil, a hardy attachment therefor comprising a hardy movable on and off the anvil, a vertical shaft attached to said hardy, means for moving said shaft vertically upward, and spring means coacting with the shaft to impart rotative movement thereto at a predetermined point in the upward movement of the shaft to carry the hardy into an operative position on the anvil, a support, and means connecting said spring means to the support so as to normally tend to impart downward vertical movement to the shaft.

4. In combination, an anvil, a hardy, a support supporting said hardy, means for imparting sliding movement to said support to move the hardy toward an operative position on the anvil, and a spring connected with the support and normally tending to move the same into a position in which the hardy is inoperative.

5. In combination, an anvil, a hardy, a shaft mounted for vertical sliding movement with respect to the anvil and attached to the hardy, an arm extending from said shaft, a spring connected with said arm to impartdownward sliding and rotative movement to the shaft for corresponding actuation of the hardy, and means for upwardly sliding the shaft.

6. In combination, an anvil, a shaft movable longitudinally and rotatively, a hardy carried by said shaft, the shaft being pro-;

vided with an arm adapted to engage the anvil to limit the rotative movement of the shaft, a spring connected with the shaft for imparting longitudinal movement thereto in one direction, and means connected with the shaft for imparting longitudinal movement thereto in an opposite direction.

7. In combination, an anvil, a support therefor, a bracket provided with bearings, a vertical shaft mounted in said bearings for sliding movement and rotative move ment, and having at its upper end a lateral arm, and an integral extension projecting from said arm, a hardy supported by said extension, said arm being engageable with said anvil to limit the rotative movement of the shaft, a crank arm projecting from the shaft, a spring connected with said crank arm to impart downwardly sliding movement to the shaft and also tendin to impart rotative movement to the shaft Wilel'l it is raised to bring the hardy above the anvil, and operating means comprising a link attached to the crank arm for raising the shaft by sliding movement until the hardy clears the upper side of the anvil.

In testimony whereof we aflix our signatures in presence of two Witnesses.
