ANVIL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 426,280, dated. April 22, 1890.

Application filed December 2'7, 1889. Serial No- 335,158. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. KING, of Downievillc, in the county of Sierra and State of California, have invented anew and Improved Anvil Attachment, of which the following is a full, clear, and exact description.

My invention is adapted to be attached to an ordinary blacksmiths anvil; and the object of my invention is to provide means whereby metal may be quickly and easily bent and cut oif upon the anvil.

.lleretofore when a blacksmith has had oecasion to bend a piece of metal it has been the practice to take the metal in aheated condition to an ordinary vise and bend it in the vise, or have an assistant hold a bending-piece upon the anvil and bend the metal over that; but my invention obviates this difficulty by providing means whereby the blacksmith may bend and cut off the metal upon the anvil without the help of an assistant.

To this end my invention consists in a swinging arm provided with a grip and actuated by a chain or cord connected with a treadle-lever and attached to the anvil-block, so that by dopressin g the lever the grip will be swung upon the end of the anvil in position to hold a piece of metal thereon. This construction will be hereinafter fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of an anvil and block provided with my invention, with a portion of the anvil-block in section to show the manner in which the invention is at taohed, and with the grip and swinging arm depending from the anvil-block. Fig. 2 is a front elevation of the same, but showing a grip without a hardy and clasping the end of the anvil, ready for use. detail showing the manner in which the swinging arm is held and pivoted to the anvilblock, and Fig. t is an enlarged detail of the pivot end of the swinging arm.

The anvil A and anvil-block B are of the usual construction, except that the anvilblock is hollowed out upon each side near the bottom, so that the lever C, which is attached Fig. 3 is an enlarged thereto, will not project beyond the sides of the anvil-block and interfere with the blacksmiths work.

The U-shapcd lever C is pivoted to the sides of the anvil-block B by the pin a, and is provided with a suitable treadle'b, so that it may be easily actuated by the foot. of the blacksmith. A chain (Z is attached by one end to the lever C and by the other end to the end of an arm D, pivoted in a bracket E, attached to the anvil-block.

The arm D is provided at its free end with a grip e, which is of a rectangular shape and is large enough to clasp the end f of the anvil and to admit a fair-sized strip or bar of metal between it and the face of the anvil; and the other end of the arm is formed into a disk g, which is pivoted between the pro jecting sides of the bracket E by the bosses or strips g, and the disk is provided upon its periphery with a groove, as shown in Fig. 2, to receive the chain or cord d.

The bracket E is provided with flanges 9, having screw-holes therein, by means of which it is attached to the anvil block B. The bracket E is also provided upon each side with a vertical slot j, enlarged and circular at the upper end, which circular ends receive the bosses or strips g by which the arm D is pivoted to the lug, and from the bosses 9 project axially the pins h. The arm D will be capable of a vertical movement in the bracket E a distance corresponding to the length of the slots 7'.

The strips 9 are attached to the sides of the disk g, or may be made integral with it and project therefrom so that they will enter the slotj of the bracket E and turn in the upper enlarged circular part of the slot. The strips are so attached to the disk that when the arm D is in a vertical position and the treadle-lever C is depressed they will slide into the lower part of the slotj and will be retained by the sides of the slot so that the arm D cannot be tipped down.

Springs 7e are attached to the anvil-block B and extend outwardly along the sides of the bracket E and underneath the ends of the pins 71., which project from the bosses or strips g and press said pins and strips to the top of the slot j of the bracket E, so that when the arm D is in a vertical position, with the grip e clasping the end f of the anv ii, the springs acting upon the pin 7?, strips g, and arm D will hold the grip in an elevated position, as shown in Fig. 2, so that there will be a space between the top of the grip and the face of the anvil, in which metal may be inserted and held, as hereinafter described.

The chain 01 is attached to the lever 0 directly und erneath the bracket E, and the other end of the chain is attached to the disk g of the arm D, near the inner side of the arm when it is in a vertical position, so that when the arm is tipped down, as shown in Fig. 1, the chain d will be wound nearly around the disk 9, as indicated by the dotted lines in the same figure.

When the foot is placed upon the treadle Z), the lever O is depressed, the chain 0?! is tightened, and this, acting upon the disk turns the disk upon the strips g in the enlarged part of the slot 3' and raises the arm D, so that the grip 6 will clasp the end f of the anvil with the grip in an elevated position, with a space between the top of the grip and the face of the anvil. Byincreasing the pressure upon the treadle b the pins h, which bear upon the springs lo, will depress the springs, the strips 9 will slide downwardly in the slots 7' of the lug E, and the arm D will drop vertically, thus bringing the grip e firmly upon any metal which may be between the grip and the anvil, or, if there is no metal there, the grip will be forced down to a solid bearing upon the anvil, so that the hardy Z may be used in the usual manner. By removing the pressure the springs will lift the'arm D'an'd grip e, and the action may be repeated as often as necessary.

To bend a piece of metal, the blacksmith places the end of the piece to be bent between the face of the anvil and the grip 6, By increasing the pressure upon the treadle b the grip e will be forced down upon the metal, and it will be held as in a vise, so that the metal may be bent over the end of the anvil f by a few blows from the blacksmiths ham- The grip 6 may be provided at the top with a hardy Z, so that by forcing the top of the grip 6 upon the face of the anvil A to make a solid bearing a piece of metal may be cut off upon the hardy Z in the usual manner.

This invention is especially valuable to the blacksmith in fittinghorseshoes. By pressing upon the treadle b the grip e and hardy Z will be thrown into position in the manner described for cutting the heels of the shoe, and by removing some of the pressure the springs 70 will raise the grip 6, so that the shoe may be held between the grip and anvil and turned into the required shape.

WVhen the grip e or hardy l is not in use, the arm D is tipped down into the position shown in Fig. 2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an anvil and anvil-block, of a vertically-swinging arm pivotally attached to the anvilblock, having at one end a grip adapted to clasp the end of the anvil, and means for actuating said arm, substantially as described, and for the purpose set forth.

2. The combination, with an anvil and anvil-block, of a vertically-swinging arm pivotally attached to the anvil-block, having at one end a grip adapted to clasp the end of theanvil, and having the other end connected by a chain or cord with a suitable lever for actuating said arm, substantially as described, and for the purpose set forth.

3. The combination, with an anvil and anvil-block, of a vertically-swinging arm pivotally attached to the anvil-block, having one end provided with a grip adapted to clasp the end of the anvil and a hardy for cutting off metal, and the other end connected by a chain or cord with suitable treadle-lever for actuating saidarm, substantially as described.

4. The combination, with an anvil and anvil-block, of avertically-swinging arm pivotally attached to the anvil-block, having one end provided with a grip adapted to clasp the end of the anvil, the other end connected with a suitable lever for actuating said arm, and a spring for raising said arm to the top of its bearings, substantially as described.

5. The combination, with an anvil and anvil-block, of a slotted bracket, an arm pivoted in said bracket having one end adapted to clasp the end of the anvil, a treadle-lever, and
