IMPROVEMENT IN RAILWAY RAIL-JOINT.

The :Schedule referred to in these Letters Patent and part of the' same To all whom it may conce/rn:

Be it known that I, EDMUND l?. DWIGHT, of the city of Philadelphia, iniV the State of Pennsylvania, have invented a new and useful Improvement in Rail- Joints; and Ido hereby` declare the following to be.I f a full, clear, and vexact description ofthe same, which will enable others skilled in the art to which it appertains to make and use my invention, reference being had'to the accompanying drawing which forms a part" .ofthis specification, and inrwhich- Figure 1 is a side View of myy improved rail-joint; .Figure 2, a transverse section of the same-,taken ,on the line l 2, fig.` 1 and- Figure 3, a perspective view ofthe stop-washer.

The same letters denote the same parts in all the figures. Y V

A and A' represent the adjacent ends of two contiguous rails. V r

4 B B'aretwo clamps', each constructed so as to embrace :ind support the bases of the rails and with the lower part bent downward to form a liange, as shown at b b. The end of one of these flanges is again bent, Vso as to `form a shoulder or second ange,.which serves as the bea-ring for the flange of the opposite clamp.

i Theconstruction thus far described is oldan'd well known, but my improvement upon it consistsin beveling the contiguous bearing. ends of the anges, as

shown at az, tig. 2.

Each of the clamps B B is perforated forthe pas-- sage of bolts C. When the bolts are inserted Vinto their position, the head of each bolt bears against the under side of one of the clamps, and a metal block, j', bearing against the under side of theopposite clamp, is then slipped 'over the bolt as far as the flange of thevclamp permits. A stop-washer is` then slipped over the end of the bolt and against the'metal block, after which the-nut d is screwed on, and the ends of the washer bent upon the'nnt and block, as shown at i fi',

fig. 3.

In theoperation of these devices, the nut cannot turn without turning the stop-washer and metal block, whichv latter, as well as the head of the bolt, is prevented from turning .by the clamps. By this means-I prevent the joint from loosening under the jar of passing trains.

4 What I claim as my invention, and desire to secure 'by Letters Patent of the United States, is'

1. T heclamps, 'constructed' each with aange, thc end-of one of which flanges is formed into a beveled shoulder for the bearing of the beveled end of the oppositeflange.

2. The combination of the clamps, bolt, metal block,

-stop-washer, and nut, when these partsare constructed and arranged to operate as described. l
