REPAIRING RAILWAY-BARS.

To all whom t may concern Be it known that I, JOsEPHD. CAwOoD, of the town of Marshall, county of Calhoun, and State of Michigan, have invented a new and useful improvement in the common anvil or swage-block for the purpose of welding up and reforming the ends of railroad-rails when t-hey have eXfoliated or become shattered from unequal wear occasioned by the inequalities of the road, siX

. inches or so of the eXtreme end of the rail being frequently destroyed, while the remainder is perfectly sound; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part in this specification, and giving a perspective view of the machine, A representing the bed sill on which the anvil is placed; B, the anvil orswage block, of cast iron; C, C, recesses or dies across the `face,`the shape of the side of the rail; D, solid block making a part of anvil, with its side shaped to the side of rail while placed in its natural position; E, a movable press block held down to anvil by dovetail tongues a on the anvil and grooves in the movable press block and Operated by two eccentric cams F back and forth in a longitudinal direction to press the rail together while forming its end and with sufficient travel to eXtricate the rail without altering its vertical position; G, a rail of the T form in its position, between the press blocks.

I usually make `my improved anvil and swage block of cast iron between four and five feet long and 16 inches wide across the face, with two forms or recesses `C C at one end, right and left, of a form corresponding wit-h the side of the rail; close to these is cast a raised block D nearly as high as the rail, and with its farthest edge also shaped to fit the side of the rail when it lies across the Specification of Letters Patent No. 15,687, dated September 9, 1856.

of a vise. This block I Work by two eccentric cams F on a shaft, which is attached to the anvil by two standards I-I, I-I, with bearings I, I, either cast on, or bolted to the edge of the same, so that half a turn Of the crank will move the press block over a space a little more than the eXtreme width of the rail. l

The mode of using this machine, is eX- tremely simple and effective. A piece of iron (being of a size suitable to the deficiency of the rail) having beenprepared and put in the fire, the rail being suspended by its middle to the level of the anvil, is brought to a welding heat, and then swung around fromthe fire into the space between the two blocks, where it is by a half turn of the crank, pinched together by means of the cams F. The welding piece is then laid on the top of the rail and welded to the rail,in the usual way, and leveled up and shaped by a swage, held by the smith, of the form of that section which projects above the blocks-thus accomplishing at one heat, what usually requires three Or more. Should any imperfections remain, which is not usual, if the first Operation is properly gone through with, they can be removed by proper hand swages, after placing the rail in the recesses C C for that purpose.

I do not claim the anvil block nor its recesses, but

What I do claim as my invention and desire to secure by Letters Patent is- The movable press block E having its edge formed to the side Of the rail Gr in combination with another block D, with its edge of a similar but reversed form, (the mov able blocks to be Operated by 2 cams or in any other convenient manner) for the purpose of pressing between them a T or otherwise shaped rail, thereby greatly facilitating the `diflicult operation of welding and re'- newing the ends of such rails after they have been damaged in the manner herein described and set forth.
