TIE PLATE.

Application filed August 12, 1925. Serial No. 49,831.

My invention relates to an improvement in tie plates to furnish a seat for therail in railway construction, so that the said rail may be firmly secured and supported upon the cross ties.

In the ordinary securing of a rail to the cross tie, the rail is either seated directly upon the tie or has beneath it a plate of iron or steel. These plates, when used, do not avoid wear upon the tie which is ordinarily of wood, and where the plate is not used, the rail itself, under the agitation and vibration of traffic, wears away the tie to such an extent as to alow the rail-movement relative to the tie to impair the firm support of the rail.

It is an object of my invention to provide a tie plate which will fit firmly upon the tie and support the rail so that no movement of the rail relative to the plate, or of the plate relative to the tie, may occur.

It is also an object to provide a tie plate which may he quickly and easily secured upon the tie, and on which the rail may be quickly secured and firmly supported.

Other objects and advantages of the invention will more clearly appear from the detailed descriptiofl which follows.

Referring to the drawing herewith, Fig. 1 is a broken side elevation of a cross tie showing my tie plate thereon, the rail being shown in transverse section. 2 is a top plan view of the plate, the rail being in section on a line 22 of Fig. 1. Fig. 3 is a broken side elevation of a rail supported upon a plurality of cross ies, each of which is provided with my improved plate. Like numerals of reference are employed to designate like parts in all the views.

In the present construction of railway cross ties, it is common to saw these ties from wood in certain lengths and widths, and I contemplate forming my tie plates of usual sizes of cross ties which are used upon railways. In'the drawings I have shown a broken section of cross tie, indicated at 1. and upon thisis placed my improved tie plate, indicated generally at 2. The plate is approximately rectangular in shape, having its ends b'ent downwardlyto form side flanges 3, spaced apart the proper distance to include between them the usual cross tie. These side flanges 3 fit the tie so accurately that no longitudinal movement of the tie will be possible.

The upper portion of the plate is provided with a longitudinal slot of suflicient width to receive the base 5 of a rail. One side of the slot has a portion of the plate bent upwardly to form a lip 6, which, when the base 5 of the rail is seated in the slot 1, will projectover the upper edge thereof to maintain the rail base firmly in position, thus doing away with the necessity of other clamping means upon that side of the rail. The plate 2 is of suilicient thickness to correspond with the ordinary base 5 of a rail so that the rail will contact at both sides of the cross tie with the upper edges 7 of the side flanges 3. It will therefore rest at each side of the tie upon the plate, and be supported laterally by the side walls of the slot 4, into which it fits.

The plate 2 has two recesses to receive the spikes 8. Said spikes are approximately square in cross section, but slightly wedge shaped at their lower ends. The recesses are as long as the spike is wide, but not quite so deep as the spike is thick. The result is that the spikes 8 serve to wedge the rail resiliently beneath the lip 6 when they are driven into place. The heads 9 of the spikes further act to hold the rail in position. A spike 8 on the opposite side of the plate is driven through an opening therein to hold said plate to the tie.

In the use of this device, the plate may be placed upon the tie. and the rail inclined somewhat so as to bring the edge of the base 5 beneath the lip 6, after which it may be dropped into slot 4, into which it will fit snugly. The spikes may then be driven into place and the rail is secured. It has been found that when thus mounted upon the tie plate the wear of the rail relative to the plate and to the tie is very slight, and the mounting will not have to be altered or adjusted for long periods of time. It is believed that the further advantages of this construction will be plain to those skilled in the art without further description.

VVhatI claim as new and by Letters Patent is:

1. A tie plate for securing a rail to a cross tie, comprising an approximately rectangular plate, end flanges on said plate bent plate relative to the desire to protect ill) ltll) downwardly to fit on each side of said cross tie, said plate having a slot therein adapted to receive the base of said rail, a lip on one side of said slot adapted to fit above the base of said rail, said plate having recesses therein opposite said lip to receive spikes for securing said plate and rail to said tie, said spikes being adapted to Wedge between said plate and said rail to force said rail be neath said lip.

2. A. tie plate for securing a rail to a cross tie, comprising a plate of rigid, Wear-resisting material, having its ends bent down- Wardly to fit the sides of said tie, a slot in said plate to receiv the base of said rail. there being openings on one side of said slot to receive spikes to secure said rail and plate to said tie, and overhanging means on said plate to secure the opposite side of said rail to said plate, spikes in said openings of sufiicient thickness to Wedge said rail beneath said means in the manner described.

3. A tie plate for secuiling a rail to a cross tie, comprising a plate of metal having a transverse slot therein to receive the base of said rail, an overhanging lip on one side of said slot, said slot having recesses in the edge opposite said lip, said recesses being at slightly greater length than Width, and spikes adapted to be driven in said recesses, said spikes being of slightly greater thickness than the Width of said recesses, and adapted to Wedge said rail beneath said lip.

In testimony whereof I hereunto aifix my signature this 5th day of August, A. D. 1925.
