TIE-@LATE The present invention relates to new andv useful improvements in railway roadbed appliances and has particular reference to a new and improved tie-plate for supporting railway rails on wooden ties or the like.

The primary object of my invention is to provide a tie-plate of the class described having meansfor reinforcing the rail holding element, which in the present instance would be the usual spike, means for preventing lateral displacement of the rail, and means for preventing skidding of the tieplate on the tie.

Another object of my invention is to provide a tie-plate of the class described formed from a single casting with the element mentioned in the foregoing associated therewith whereby to reduce the cost of manufacture of such devices without materially reducing their effectiveness.

Other objects and advantages to be derived from the use of my invention will appear from the following detail description and the claim, taken with an inspection of the accompanying drawing, in which Figure 1 is a perspective view of a rail and tie showing my improved tie-plate applied in operative position;

Fig. 2 is a top plan view of the same; and

Fig.`8 is a bottom' plan View of the same.

Referring more particularly to the drawing, wherein similar characters of reference designate like and corresponding parts throughout the various views, 1 designates the body portion of my invention which is rectangular in configuration in the -preferred form of the device. The intermediate portion of the plate l receives a rail, a plurality of intersecting grooves 2 being diagonally arranged on the upper face of said plate to permit moisture to drain between the rail and the plate.

The upper face of the plate l is also provided with reinforcing elements, said reinforcing elements being formed of lugs 3 having vertical walls thereof arranged adjacent apertures et formed in said late.

These lugs 3 serve to reinforce the rail' old` lthe plate 1, said vmanently collect between the specification of Leiters ratent. Patented Sept, g5, 1191"; Application filed May 23, 1916.

ing elements which in the present instance are the usual spikes 5, best shown in Fig. 1. An intermediate reinforcing lug 6 is providedhaving the vertical end wall thereof engaging a rail. It will be seen that in the provision of the lug 6 I afford means for preventing spreading of the rails, one of the most predominant causes of wrecks on railways at the present time, this lug 6 being found particularly useful when used in connection with the outside rail on a curve. A second pair of apertures 7 are provided in at a distance fromt ie apertures 4 and being adapted to receive spikes or similar fastening elements.

The under side of the plate 1 is provided with a plurality of intersecting diagonally arranged ribs 8 and 9, there being sets of each at each end forming a chamber 10 approximately centrally of the under face of the plate whereby to form means for preventing lateral or. longitudinal displacement of the plate on the tie. It will be obvious` that when the spikes are driven home the chamber 10 forms a suction on the tie assist' ing in maintaining the plate against displacement. In Fig. l I have shown a rail way rail 11 of the usual formation and a.l tiev l2. In the present instance the tie isl formed of wood, but, of course, it will be understood that various. materials may be substituted therefor. A pair of flanges 13 and 1.4L extend along the longitudinal marginal edges of the plate 1 and extend downwardly from the .under face thereof, said iianges assisting in preventing lateral displacement of the tie plate.

In the use of my improved tie plate it will be seen that not only are the A@staining elements, such as the spikes 5, prevented from distortion under strain, but the rail itself is prevented from being laterally moved, ordinarily termed spreading In manu faoturing my device the cost will not be materially increased over the cost of the tieplate now in use, but the effectiveness of the device is materially increased. It will be readily apparent that no moisture can perrail and the tie owing to capillary action, which in the present instance is the drain 2.

From the above description taken in connection with the accompanying drawing,it

is thought that a clear and comprehensive a ertures being arranged prevented by means of' understandingI of the. construction, operation and advantages of my invention may be had, and while I' have shown and described my invention as embodying a specific strucv ture, I desire that it be understood that I may make such changes in structure as do not depart from the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

The combination in a tie plate of the class i t. described, of a body portion having a pair of openings on each side thereof, lugs formed on the said body portion adjacent the rear., edges 0i the openings on the uppei face thereof, a reinforcing lug formed intermediate the said lugs for engagement with a rail, Ythe said body portion being provided with a pair of intersecting recesses terminating at a pointl adjacent the outer edge of the formed by the intersecting of the said ribs. to prevent displacement of the plate on thi.1

tie. v

In testimony whereof, Iaiiix my signature hereto.
