Patented Mar. 15, 1932 UNITED. STATES THOMAS A. DIMETROFF, OF FR-EEIVLANyWASI-IINGTO-N RAIL mrrnn Application filed December 3, 1930. Serial No. 499,832

This invention aims to provide a novel fulcrum member, adapted to support a bar, whlch is used to raise a railroad rail, so

that a tie plate can be slid under the rail.

It is within the province of the disclosure 1 to improve generally and to enhance the utility of devices of that type to which the I invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combine,

tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes rearwardly inclined, pointed prongs 8.

in the precise embodimentof the invention herein disclosed, may bemade withinthe scope of what is claimed, without departing from the spirit of the invention. In the accompanying drawings: Figure 1 shows in elevation, a device con structed in accordance with the invention, parts being broken away;

Figure 2 is a top plan;

Figure 3 is a bottom plan of the fulcrum member;

Figure 4 is an elevation ofthe fulcrum member;

Figure 5 is a section on the line 5-5 of- Figure 2.

The numeral 1 marks the railroad tie, and the numeral 2 designates the railroad rail. Thenumeral 3 indicates a tie plate. The numeral 4 designates a bar, which, being introduced under the ball of the rail 2, is used to raise the rail, so that the tie plate 3 can be slid to place between the tie 1 and the rail 2. V

For the support of the bar 4 there is provided a fulcrum member, including a flat metal plate 5 provided near to its forward edge with a plurality of holes. 6. Parallel slits 7 are formed in the plate 5 in advance of the holes 6, the slits 7 communicating with the holes 6. The material freed in theformation of the slits 7 is forced downwardly,1as in Figure 5, toform downwardly extended,

The fulcrum member includesv an inverted, U-shaped metal bracket-comprising downwardly diverging legs .9 having outwardly extended feet 10 connected by securing elements 11 with the base plate 5. The upper ends of the legs 9 are connected by a saddle shown at 14, from front to back, and is concaved, as shown at 15 from side to side. The bracket is forwardly inclined, as shown at '12. The saddle 12 is upwardly convexed, as

16, to overhang the forward edge'of the base plate 5.

In practical operation, the bar-4 is engaged a under the ball of the rail 2, and is mounted,

intermediate its ends, in the saddle 12 of the fulcrum member. Because the saddle 12' is upwardly convexed from front to back as shown at 14, the bar 4 can rock readily on the saddle. Because the saddle is concaved,

as shown at 15, from side toside, the bar will not readily slipoff the saddle, .sidewise. The I bracket of the fulcrum member is forwardly inclined at 16, and the prongs-8am down wardly and rearwardly inclined, as shown in Figure 5. The result is that when pressure is put on the bar 4, to lift the rail 2, there is a tendency to slide the fulcrum member, as a ,whole, backwardly, a little, and thereby embed the prongs 8 in the tie 1, the backward movement ofthe fulcrum member thus being i stopped, and the fulcrum member remaining securely in place, as a support for the bar 4.

If, for any reason, it is desired to fasten the base plate down permanently, it canbe done by driving spikes through the exposed holes 6 of Figure 2. -Ordinarily,-however, and in the operation shown in Figures 1 and 2, there is no occasion for spiking down the 7 base plate, prongs 8 being entirely adequate to hold the plate against/backward move ment. It is only in unusual jobs, or where the fulcrum member is to remain in place fora long time that it may be desirable to spike it down through the holes6.

The device forming the subject' matter of I this application, is simplein construction, but it will be found thoroughly eifectiveto support a bar, such as the bar 4, when new ties'have been put in,and when it is necessary to raise the rail, in order that'the tie plates may be slid under the rail.

The structure hereinbefore described, willi be found to be of peculiar utility in replacing tie plates during the process of putting in new ties.

Having thus described the invention, what is claimed is:

In a device for raising railroad rails, a fulcrum member comprising a base plate and an upstanding bracket on the base plate, the v bracket being provided at its top with a saddle which is upwardly convexed from front to back, and concaved from side to side.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

THOMAS A. DIMETROFF.
