RAIL-CLAMPING DEVICE FOR THlN OR SHEET METAL RAILWAY-TIES.

SPECIFICATION forming part of Letters Patent N 0. 671,607, dated April 9, 1901.

Application filed August 15,1900. Serial No. 26,923. (No model.)

To all whom, it nuty concern:

Be it known that I, CY RUs OLDROYD, a citizen of the United States, residing at Morrisdale Mines, in the county of Clearfield and State of Pennsylvania, have invented a cerrain new and useful Improvement in Rail- Clamping Devices for Thin or Sheet Metal Railway-Ties,of which the following is a specilication.

My invention relates to rail-clamping devices for thin or sheet metal railway-ties.

My invention is illustrated in the accompanying drawings, Wherein Figure 1 is a side elevation of a tie with a section of rail secured in position according to my invention, with the parts shown in two positions by means of dotted lines. Fig. 2 is a longitudinal section through the same. Fig. 3 is a plan View of the same. Fig. 4: is a side elevation of a modification.

Like parts are indicated by the same letter in all the figures.

A is a thin or sheet metal railway-tie, and the same may be made of pressed steel. In that form of my invention which is shown in Figs. 1, 2, and 3 this railway-tie has certain holes and lugs struck on it, preferably by means of a die at one action. These parts consist of the flange B, the side lugs O O, the bolthole D, and the slot E.

F illustrates a section of the rail.

G is the rail-clamp, which has the two side lugs O to engage the lug O, the flange B opposite the flange B, the bolt-hole for the bolt D and the inner downwardly-depending wedge-shaped projection H. This clamping device may be made of the same material as the tie and may be made and formed in the same manner.

The application of the clamping device to the tie is readily seen by reference to Fig. 1, where in dotted lines the clamp is shown in the first position of application. Now if the outer end of the clamp be forced downwardly toward the tie it is evident that the lug C will take under the lugs O, the flange B will overhang the flange of the rail, and as the outer end of the clamp is further depressed the wedge or are shaped piece H will engage the outer end of the slot E and force the clamp toward the rail, whereby all the parts will be firmly forced together in position to securely clamp the rail to the tie. The bolt D in this case screw-threaded into the parts, is then set in position. The bolt, however, can be attached in any desired manner, as by a nut on the bolt instead of a screw-thread on the tie.

The modification shown in Fig. 4 differs principally in this, that the arc-shaped or wedge-shaped portion of the clamp is on the outside, and instead of the slot against the end of which it is intended to bear the pin J is substituted. The action, however, is substantially the same in each case.

It will be evident that considerable modification can be made in the form of this device, and Ihave simplyshown these two forms to give a good illustration of the general nature of my invention without desiring thereby to limit myself to the particular form shown.

I claim 1. A clamp for railway-rails, comprising a flange on the tie to overhang one of the railflanges, sidelugs on the tie below the railand a movable clamping device, having lugs adapted to take under the side lugs on the tie and a flange adapted to overhang the other flange of the rail and an are or wedge shaped projection adapted to take against a portion of the tie and, when the clamp is pushed into position by its wedging action, to force the parts securely into place.

2. A clamp for railway-rails, comprising a flange on the tie to overhang one of the railway-flanges, side lugs on the tie below the rail and a movable clamping device, having lugs adapted to take under the side lugs on the tie and a flange adapted to overhang the other flange of the rail and an are or wedge shaped projection adapted to take against a portion of the tie and, when the clamp is pushed into position by its wedging action, to force the parts securely into place, and a securing device to hold the clamping-piece in such final position.

3. In a rail-clamping device, the combination of a sheet or thin metal tie, having a flange on the top and projections on the side, with a clamping-piece, having lugs and a flange at its forward end to coact with the lugs ar'id flanges on the tie, and a slot in the tie and a downwardly-depending wedge or are shaped projection on the clamping-piece adapted to pass into said slot.

4. In avail-clamping device, the eembinaadapted to pass into said slot, said several tion of 2'; sheet or thin metal tie, having a flanges, lugsand' projections formed respec- 10 with a clamping-piece, having lugs and a flange at its forward end to coact with the lugs and flanges 0n the tie, and a slot in' the Witnesses:

tegrai therewith.
