IMPROVEMENT IN RAILRQAD-RAIL JOINTS.

Specification forming part of Letters Patent No. 177,7S5dated May 23, 1876; application led Y April 2o, 1876.

Z'o all whom 'it may concern:

`"Be it known that I, CHARLES F. ARNOULD, of Titusville, in the county of Crawford and State of Pennsylvania, haveinvented certain new and useful Improvements in Railroad- Rail Join ts; and I do hereby declare the following to be a full, clean-and exact descripl tion of the invention, such as will enable others skilled in the art towhich it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specication.l

My invention relates to an improvement in railroad connection-locks for uniting the ends of rails; andit consists in the arrangement and combination of parts which will be more fully described hereinafter, whereby the usual lish-plates, bolts, and the making ot' holes in the rails are entirely done away with, and at the same time a stronger and a better lock produced.

y The accompanying drawings represent r'ny invention. i

a represents the bed-plate,- which is made long enough to extend from tie to tie, and

which has four stays, c, formed upon its face, Y.

two of which catch against the sides of each rail near its end, and thus' prevent any side motion or displacement. Hinged to each edge ofthe platea, just opposite where the ends of the two railsd meet, are the two clamps e, so shaped at their inner edges as to catch over the flanges formed on the lower edges of the rail, and against the sides of the rail, and thus hold it irmly and securely in position. By hinging these clamps e to the bed-plate by means ofthe staples g, the clamps 'can never in the bed-plate sufficiently tar to have wedge, o, driven through it, as shown. The

wedge is of a concave semi-cylindrical form,

and, passing through both links, it draws both clamps down tightly upon the rails.

` It will be readily seen that the usual lishplates and bolts are done away with, and that no cutting of the edges of the rail or drilling holes through them is necessary. It can be adjusted between ties, and in a moment of time 5 it saves labor and timein applying them; does not interfere with the expansion of the rails; it holds the ends so rrmly thatthey cannot Abe bruised by shaking or jarring; b esides many other advantages which will readily suggest themselves to those familiar with the usual fastenings.

Having thus described my invention, I claim l. The combination of the bed -plate a,

clamps e, and staples g, substantially as shown.

2. The combination of the clamps c, having the linksh secured thereto, slot t', and wedge o, substantially as described.

' In testimony that l claim the foregoing I have hereunto set my hand this 11th day of April, 1876.

CHARLES F. ARNOULD. Witnesses:
