B. A. ELLISON.
Reversible Anvils. Y No.52,351. APatentedme 23,'181`4-.
UNITED STATES PATENT OFFICE.
BENJAMIN A. EIILISON, OF EXETER, NEV HAMPSHIRE.
IMPROVEMENT IN REVERSIBLE ANVILS.
Specification forming part of Letters Patent No. 152,35l, dated June 23, .1874; application filed April l, 1874.
To all whom it may concern:
Beit known that I, BENJAMIN A. ELLIsoN, of Exeter, of the coun-ty ot' Rockingham and State of New Hampshire, have invented an Improved and useful Reversible Swage-Block or Anvil; and do hereby declare the saine to beully described in the following specification and represented in the accompanying drawings, of which- Figure l is'a front elevation, Fig. 2 a top view, Fig. 3 a transverse section, and Fig. 4 an end elevation, ot' the swage-block and its supporting-frame.
In such drawings, A denotes a block of metal, in the form of a rectangular prism, rabbeted along one edge, as shown at c, and having two journals, b b', projecting' from its opposite ends. Furthermore, the block has a series of swagc notches or recesses, c or el, made in each of its opposite edges, such varying in width and depth, as occasion may require. It also has another series of swage recesses or notches, c, leading from the rabbet, as shown. In other words, the rabbeted edge is provided with two series of such notches, the lowermost ot' which are closed at their inner ends, such closing of them being convenient for finishing the end ot' a bar during the process of swaging it. The rabbet also causes the notches of one series to be e11- tirely above those ot the other, with a space or distance between the two series, such enabling any one of the upper series to be used for some kinds of work or articles which could not be swaged by it were it on a level with the notches of the other series. One of the journals is nicked or slitted diametrically across its end, with two slots, fg, at right an gles to each other, such being to receive a spring-latch, B, fixed to the end of the supporting-frame C of the swage-block, and arr. nged with it and the swage-block in manner as shown. Furthermore, the swageblock also has a series of holes, h, made in or through it transversely from one or both sides of it, such holes being what may be termed punchholes,77 as they enable the block to be used in supporting a plate or bar while being punched, the bar or plate resting upon the block and over one of the holes, so that the part separated by the punch may be driven through the hole.
'llhe block may be revolved in its frame so as to bring either edge or side of the block uppermost, as occasion may require, the block being held in either ot its four lpositions by the spring-latch, and one of the slits for its reception.
A swageblock so made is very useful for blacksiniths, especially in the making of nuts or other forged articles of metal for carriages.
The block may be made without the rabbet, and with but one set of notches in each of its opposite edges; but it will not be so exl tensively useful as when it is connected with the rabbet, and two ranges of notches in one edge, disposed as represented.
I do not claim a rotary swage 'made as described in the Patent No. 88,125, as my swage -is not a circular block with swage-notches formed in its periphery in the direction of its axis, my swage being a rectangular block, having the notches in its opposite edges, and each in a direction at right angles to the axis ot' motion, or ot' the journals ot the block. This enables me to bring all ot' one range ot' notches in one horizontal line, and avoids the necessity of turning the block preparatory to the use oi' each notch.
I claim- 1. A rotary swage-block having not only a series of punch-holes, h, made in or through it laterally from one or both sides of it, but provided with pivots or journals b b at its oppositeends, and two series of notches, c d, arranged in its opposite edges, all being substantially as described.
2. A rotaryswage-block, not only rabbeted on one edge, and there provided with two series of swage-notchcs, c c, all substantially as represented, but provided with a series of swage-notches, d, in its other edge, and two journals, b b', projecting from its ends, all being essentially as specified.
BENJAMIN A. ELLISON.
