I UNITED sr-ArEs PATENT oFF- oE- IVAN '1. BRANSON, or'sroox'roiv, CALIFORNIA.

To all whom it may concern s, Be .it known that I, vIvan T. BRAnsoN, a citizen of the UnitedStates of Amer1ca,-re

siding at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful. Improvements in Rotary Anvils; and I do declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in anvils and particularly to that type used under steam and trip hammers and the like, the principal object being to produce an anvil which has a plurality of faces, any one of which may be positioned and held directly under the hammer head.

A further object is to provide the faces of such anvil with recesses of difierent sizes and forms, to serve as dies whenever any particular shape is desired in the metal being forged.

In present practice, the anvils have a single flat face and if it is desired to bend a piece of metal under the hammer or shape it in any way, blocks of iron are laid on the anvil or a single die having the desired shape is placed thereon.

When the hammer drops to bend a piece of metal between the blocks, these blocks fly off the anvil to a considerable distance, and are apt to injure the workers or cause other damage. In the case of the dies, each one is temporarily secured to the anvil when wanted, and then taken off again. This is a process consuming much time and each die form being separate, results in their becoming mislaid about the shop.

With my improved anvil, any desired die form may be adjusted under the hammer head with a very few minutes work, and the anvil and dies being integral, no parts can fly off or get lost.

A still further object of the invention is to produce a device which will be simple and inexpensive and yet one which will be exceedingly efficient for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of ROTARY AiWILl Specification of Letters Patent.

the parts aswill fully appear by a perusal of the following specification. and; claim;

On the drawings, similar characters of reference indicate. corresponding parts in the several, views i Figure 1 is a side elevation of the anvil as-setnp. 5w j I Fig. 2 is an endlelevationof the anvil block removed from its bearings.

F i2. 3 is an enlarged section taken on a line 3-3 of Fig. 1 showing a lockingdevice.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the base or pedestal of the anvil composed of two units bolted to the floor, one on either sideof the anvil block 2. 7 This anvil block is formed with a plurality of faces 3, preferably siX, one of which faces is fiat; another has an oval depression, as at 4, for the plain bending of metal plates,

bars, etc; another has a plurality of differ-- ent sized square shaped dies, as at 5; and others circular dies, as at 6. V

A shaft 7 projects on either side of the block 2, on the outer ends of which shaft are flanges 8. The anvil block, shaft and flanges are preferably formed of one piece of metal for the sake of rigidity, but of course could be constructed separately and held firmly together by any suitable means.

The shaft 7 is rotatably journaled in the recesses 9 when it is desired to turn the anvil 2. The recesses 9 are so positioned that a pair of such recesses will always be in position to engage with the blocks 10 when the anvil is turned to present another face to the hammer. I

If desired, a similar faced block may be mounted to the hammer head, each face registering with the corresponding face on the anvil block. This device of course is adapted to be used with drop hammers, trip hammers or may be used as a plain anvil.

All parts thereof are of course so proportioned and positioned to present a rigid surface to the blow of the hammer and be as vibrationless as it is possible to make the same. 7 7

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such devia tions from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended c aim.

Having thus described my invention, What I claim as new and useful and desire to secure by Letters Patent is A rotary anvil comprising a base, an

anvil block having a plurality of faces, a

shaft on the block journaled in the base, flanges on the outer end of the shaft, a plurality of notches in the periphery of the flanges, and locking blocks pivotally mounted to the base and adapted at one end to engage with the notches whereby the shaft and anvil block thereon are held in a pre determined position. a

In testimony whereof I afliX my signature in presence of two Witnesses.

IVAN T. BRANSON.
