'SWQAGE-YBLOCK.

SPECIFICATION forming part of Letters Fatent No. 727,885, dated May 12, 1903. Application filed October 3, 1902- Serial No. 125,765. (No model.)

To all whom it may concern:

Be it known that I, HORACE BENJAMIN BLOOD, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented a new and Improved Swage-Block, of which the following is a full, clear, and exact description.

The invention relates to swage-blocks such as shown and described in Letters Patent of the United States No. 700,724, granted to Benjamin F. Blood on May 27, 1902.

The object of the invention is to provide a new and improved swage-block designed for the use of blacksmithsand other iron-workers and arranged to permit of securely clamping the anvil in the desired position and to.

allow of a quick release of the anvil-whenever it is desired to adjust the anvil to a different position. I

The invention consists of novel features and parts and combinations of the same, as

will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the improvement. Fig. 2 is a plan View of one end of theimprovement, parts being shown in sec-' Fig. 3 is a perspective view of part of tion. the clamping device. Fig. i is a side elevation, partly in section, of a modified form of the improvement. Fig. 5 is a similar view of another modified form of the improvement.

Fig. 6 is a like view of another modified form or secured on the top of standards D D, conected with each other at their lower ends by ods E, as plainly shown in Fig. 1. A clampto, so that further description cal recesses D for engagement by the ends of the anvil to hold the same in either a horizontal or vertical position at the time the standards D and D are drawn together by the clamping device, the same as shown and described in the Letters Patent above referred thereof is not deemed necessary.

The rod F of the clamping device carries at one end a crank arm or handle G under the control of the operator, and on the other end of the rod is formed a screw-thread F, screwing in a not H, the rod passing loosely through a bearing H. The bearing H and not H are removably held in the cross-bars D D of the standardsDand D, the said bearing and not being providedwith notches fitting into forks in the cross-bars to hold the bearing and nutagainst longitudinal movement, but to allow of lifting them out of the cross-bars wheneverit is desired to disconnect the clamping device from the standards- Now by turning the handle G in the proper direction a rotary motion is given to the rod F to screw the same in the nut H,-'and as the shoulder of the handle G comes in contact with the outer face of the bearing H the hearing and nut and consequently the standards D and D are drawn towardeach other.

In order to quickly release the ends of the anvil A from the standards D and D at the time the upper ends thereof are moved apart, I interpose springs I and 1 between theends of the journals B B and lugs C C formed on the bearings C O, the outer ends of the springs I and I being held on pins 0 projecting from the inner faces of the lugs 0 C and the inner ends of the said springs are set in recesses formed in the ends of the trunnions or journals B B, as plainly indicated in Fig. 2. Now when the ends of the standards D D are drawn together by a corresponding action of the clamping device then the springs I and l are compressed and the pins G" pass in to the openings in the trunnions to hold the latter and consequently the anvil A against upward movement in. the bearings C 0. As soon as the clamping device is actuated to move the upper ends of the standards D D apart then the springs I I exert their pressure on the trunnions and standards to immediately disengage the ends of the anvil from the inner faces of the standards to allow convenient turning of the'anvil to another position. This result may also be obtained by other means-for instance, as shown in Fig. 4, by the use of flanges B formed on the ends of the trunnions 01' journals E the said flanges being adapted to engage shoulders D on standards D so that when the standards move apart the corresponding shoulder D, engaging a flange B pulls the anvil A with it, so as to move the opposite end of the anvil out of engagement with the opposite standard. The end of the journal B is formed with an opening B, adapted to be engaged by a pin 0 on a lug 0 either integrally formed on the standard D as shown in Fig. 4, or bolted thereto, as indicated in Fig. 6.

In the modified form shown in Fig. 5 the anvil A is formed with conical trunnions B engaging correspondinglyshaped bearings C on the standards D so that when the upper ends of the standards are moved apart the trunnions slide down the bearings C thus moving the ends of the anvil out of contact with the inner faces of the standards. Vhen the upper ends of the standards I) are drawn together, then the trunnions B rise, and their apex ends engage lugs 0 formed on the bearings C toholdthe trunnions,and consequently the anvil, against upward movement.

The clamping device shown in Fig. 8 consists of a rod F having one end F polygonal and secured in a corresponding opening in the cross-bar D of one of the standards by heads F, held on the said end F and abutting against the faces of the said cross-bar. The other end F is threaded, and on this end screws a handled nut G, under the control ,of the operator and arranged to abut against the outer face of the other cross-bar D on the opposite standard, and the said end F extends through an elongated aperture D in the said cross-bar. A spring J is coiled on the threaded end F and rests with one end on a collar F, secured to the rod F the other end of the spring abutting against the inner face of the cross-bar. Now by screwing up the nut G on the end F against the crossbar D the standards are drawn toward each other, and at the same time the spring J is pressed, and when the nut G is screwed outward on the end F then the standards are pressed apart by the action of the spring J.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A device of the class described, comprising a frame having standards connected with each other at their lower ends, open bearings in the upper ends of the said standards, an anvil having journals engaging the said open bearings, a clamping device for moving the upper ends of the standards toward each other, to engage the standards with the ends of the anvil, and resilient means for separating the standards and the ends of the anvil on opening the clamping device to permit the anvil to turn freely on its trunnions, as set forth.

2. A device of the class described, comprising a frame having standards connected with each other at their lower ends, open bearings in the upper ends of the standards, an anvil having journals engaging the said bearings, a clamping device for moving the upper ends of the standards toward each other, to engage the standards with the ends of the anvil, a retaining device on the standards, adapted to engage the journals, to hold the latter against upward movement in their bearings at the time the upper ends of the standards are drawn toward each other, and resilient means for separating the standards and the ends of the anvil, when the clamping device is actuated to release the anvil, thereby permitting the anvil to turn freely on its trunnions, as set forth.

3. A device of the class described, comprising a frame having standards connected with each other at their lower ends, open bearings in the upper ends of the standards, an anvil having journals engaging the said bearings, a clamping device for moving the upper ends of the standards toward each other, to engage the standards with the ends of the anvil, and springs interposed between the ends of the journals and the upper ends of the standards, to move the anvil out of engagement with the standards on opening the said clamping device, as set forth.
