SPECIFICATION forming part of Letters Patent No. 700,724, dated May 27, 1902. Application filed April 5,1900. Renewed March 25, 1902. Serial No. 99,973. (No model.)

To on whom it may concern.-

Be it known that I, BENJAMIN F. BLOOD, a citizen of the United States,residing at Forestgrove, in the county of \Vashington and State of Oregon, have invented certain new and useful Improvements in Swage-Blocks; and I do hereby declare the following to be a full,

clear, and exact description of the invention,]

such as will enable others skilled in the art to to which it appertains to make and use the same.

My invention relates to iron-forging appliances, and more particularly to what is commonly termed a swage-block; and it consists in certain novel combination and con- 1 5 struction of parts, as will be hereinafter fully described, and pointed out in the claim.

The object of my invention is to provide an adjustable anvil which will be found very desirable and useful to blacksmiths and other iron-workers, and it will be seen that my improved swage-block is easily and readily adjustable and that it is provided upon its several surfaces with variously-shaped depressions, grooves, &c.

In the accompanying drawings, Figurel is a perspective View of my invention complete ready for use. Fig. 2 is a perspective view showing the frame of my swage-block, the block being entirely removed from its bear- 3o ings. Fig. 3 is a detail of a portion of the swage-block. Fig. 4: is a detail view of an attachment designed to be received by a groove or recess formed in one side of my swageblock.

3 5 In order to conveniently refer to the several details of my invention and their cooperatingaccessories, numerals will be employed, of which 1 indicates the swage-block proper or adjustable anvil, which, as will be seen, is provided at each end with journals 2, de-

signed to rest in suitable bearings or seats 3, secured to the upper ends of the frame-sections 4, said frame-sections being bolted. or otherwise secured directly to the floor or to the base members 5. The base members 5 are secured in their operative positions by the rods 6, though it is clear that in case the end sections 4 are bolted directly to the floor said rods 6 may be dispensed with. The upper portions of the end sections 4 are adj ustably secured in their operative positions by means of the clamping-rod 7, which passes loosely through anaperture provided in the cross-bar 4, attached to one of said end sections, while the opposite end of said clamping-rod is received by a threaded aperture in the cross-bar a attached to the opposite end section, and in order to adjust the clampingrod 7 so that the upper ends of the end sections 4 may be so adjusted that they will be brought to bear firmly or loosely against the ends of the swage-block a controlling handle or lever 8 isattached to said rod 7.

To each of the upper ends of the end sections 4: I secure the inwardly-directed flanges 9, designed to provide a firm support for the edge of the swage-block, and it is obvious that by a proper adjustment of the anchoring-rods 7 said projecting flanges 9 may be brought under the ends of said block when the latter is disposed in a horizontal position. It will be observed that the upper edges ofthe supports or flanges 9 are beveled in order that said flanges may be more readily brought under the ends of the swage-block, inasmuch as the lower edge of the block is normally slightly above the extreme inner edges of the flanges 9, thereby permitting said free edges to freely pass under the swage-block and insuring that when the clamping-rod 7 is properly adjusted the flanges 9 will be caused to move under the ends of the block and slightly raise the same as it rides upon said beveled edges. By this arrangement itis insured that the'flanges 9 will contact with the ends of the block, and thereby insure that it will be held in a truly horizontal plane. The central portion of the flange 9 is entirely cut away, thereby providing the notch or recess 9, the object of said recess being to receive the ends of the swageo block as the latter is adjusted in a vertical position, it being understood that the width of the recess 9 coincides with the thickness of the swage-block, thereby causing the said flange upon each side of the block to firmly engage it in such a manner that it will be held against rotation even though the clamping-rod 7 be not securely adjusted. By this arrangement it will be observed that the flanges 9 will performa double office--namely,

my improved swage-block may be readily adjusted either in a horizontal or vertical position by first separating the upper ends of the end sections t by a proper rotation of the clamping-rod 7 sufficiently to move the flanges 9 out of contact with the ends of the block, when said block may be freely turned upon the journals 2 and disposed in the desired position, when a reverse movement of the clamping-rod 7 will cause the flanges 9 to take under the ends of the swage-block in case the latter is in a horizontal position or cause the ends of said block to be received by the recesses 9 if the block is to be secured vertically. It is therefore obvious that my improved block may be quickly changed from one position to another by first turning the clamping-rod 7 so as to release the binding action of the flanges 9 against the ends of the swage-block, when said block may be freely turned upon its j ournals 2 until it is in the desired position, when the clamping-rod 7 may be so turned that it will bring the flanges 9 tightly to bear against the ends of the block, and thereby cause said flanges to engage the grooves 20.

While it is obvious that the surfaces of my improved swage-block may be shaped in any preferred manner to best accommodate the same for the varying uses to which it may be applied, yet it will be understood that I reserve the right to shape said surfaces as deemed productive of the best results. I will hereinafter set forth some of the preferred shapes and details of construction which may be applied to my block in order to fit it for the large variety of uses.

The edge of my improved swage-block is preferably provided with a series of transversely-disposed recesses or notches, as indicated by the numerals 10, 11, and 12, it being understood that any preferred number of said notches may be formed. It is thought that said recesses will prove very advantageous in assisting to form the surface of a piece of ironas, for instance, the angular recesses 10 may be employed to preserve the angles of a square rod while the other angles are being formed by the hammer, there being two sizes of said recesses. In like manner the recesses 11 will be found desirable in preserving the round side of a rod while the other side is being hammered into the desired shape. A

'series of cup-shaped recesses 13 are formed directly in the side of the sWage-block and may terminate as cup-shaped recesses or extend entirely through the block, if desired.

14 indicates a cup-shaped recess provided with an aperture 15 in its bottom, which extends entirely through the bloek and will be found desirable and useful for various kinds of work.

' 16 indicates a series of square or oblong recesses of varying sizes, which will also be found useful for various purposes. The opposite edge of my improved swage-block is preferably formed with one or more curved sections or recesses 17 of uniform or varying sizes, as'preferred, while the numeral 18 indicates a removable former designedfor various useful purposes, as for holding a part of a plow-share, enlarged recesses 17 being useful for forming horseshoes and other curved objects. The removable former 18 is provided with a flared lower edge 1 9, designed to fit within any properly-formed recess, and thereby held. reliably in an adjusted position during the movement of the swage-block.

It will be readily apparent that my improved adjustable anvil or swageblock may be quickly disposed in any desired position by first rotating the clamping-rod 7 by means of the handle 8. After the swage-block has been adjusted the clamping rod is then rotated so that its threaded end will take into its seat, when the flange 9 will be brought tightly to bear against the end of the swage-block, and thereby hold the same secured until a reverse rotation of the rod 7 is made. In order that the flanges 9 may reliably grasp the contacting surface of the end of the swage-block, I provide in each of said ends a series of radiating grooves 20, into any one of which said flanges may project after the block has been adjusted as desired. The said grooves 20 I prefer to make very shallow, as shown in Fig. 3, in order to merely roughen the surface of the end of the block, so as to insure that sufficient frictional contact will be set up between the block and the flanges 9, it being understood,however,that said grooves 20 may be made of much greater depth than illustrated in the drawings, if deemed desirable.

It will be understood that any preferred shape may be imparted to the recesses formed in the surface of my swage-block, thereby fitting said block for any special variety of work it is desired to perform, and I therefore desire to reserve the right to form said details in any preferred way as may be deemed productive of the best results.

The end sections 4, together with the base member 5, may be cast or otherwise formed in one piece, and the parts of my improved swage-block may be very cheaply manufactured and assembled in their respectve operative positions, and the complete machine may be quickly separated into its elements and placed ready for shipment or storage.

Believing that the advantages and construction of my invention have been made fully apparent, I will dispense with further reference to the details thereof.

Having thus fully described my invention,

what I claim as new, anddesire to secure by I a clamping-rod 7 and means to rotate said Letters Patent, is

The herein-described swage-block having its edges and sides provided with a plurality of forming-recesses; a-jonrnal 2 formed on each end of said block; a series of radiating grooves 20 formed on each end of the block adjacent to said journals, in combination with supporting end sections 4 having bearings Sin the upper ends thereof; flanges 9 located adjacent to said bearings and adapted to cooperate with the radial grooves 20, and

rod whereby the sections 4 may be drawn tightly into engagement with the ends of the swage-block or released, as desired, substantially as specified and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN F. BLOOD.
