BENJAMIN PASCHAL BLOODWORTI-I, OF WEST SAVANNAH, GEORGIA.

TIE-PLATE.

Specification of Letters Patent.

Application filed March 4, 1911.

Patented Oct. 24, 1911. Serial No. 612,214.

To all whom it may concern:

Be it known that I, BENJAMIN P. BLooD- woman a citizen of the United States, residing at West Savannah, county of Chatham, and State of Georgia, have invented certain new and useful Improvements in Tie-Plates, of which the following is a specification.

My invention relates to tie plates, that is to metal plates which are placed between the flange of the rail and the wooden tie.

The object of my invention is to provide an anti-creeping tie plate, that is, a tie plate which will have no tendency to move longitudinally of the tie from the constant vibration as is common with tie plates of the ordinary form.

A further object of my invention is to provide a tie plate provided with means for clamping the rail and for protecting the spikes from the wheels of the derailed cars.

Other objects will appear hereinafter.

With these objects in view my invention consists generally in a tie plate formed of two similar sections having diagonally disposed abutting edges, interlocking members on the abutting edges and the bottom faces of the sections provided with ribs which, when the plate is in position, extend transversely of the tie or longitudinally of the rail, and the ribs on the two sections being inclined in opposite directions.

My invention further consists in a rail tie plate formed of two sections having interlocking edges and each provided with an upwardly and inwardly extending U-shaped member adapted to project over the flange of the rail and impinge against the web, the sections being provided with spike holes arranged within the arms of the U-shaped member, whereby said members shall tightly clamp the rail and shall protect the spike from the wheels of derailed cars.

My invention further consists in various details of construction and arrangementof parts all as will be fully described here1nafter and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompany ng drawings forming a part of this specificatlon and in which-- Figure 1 is a top plan view of a tie plate embodying my invention in its preferred form, Fig. 2 is an end elevation of the same, Fi 3 is a bottom plan view of the plate an Fig. 4 is a side elevation thereof.

Referring now to the drawings 1 indicates the body of the tie plate which is preferably of rectangular form and provided with a flat upper surface 2. The plate is divided diagonally into two substantially triangular sections 3 and 4, the abutting edges of which are provided with interlocking members 5 and 6 respectively. The members 5 and 6 consist of a plurality of parallel tongues or fingers extending in direction longitudinally of the rail and spaced apart a distance somewhat greater than the width of the members to permit those on the opposite edges to be readily interlocked. The under faces of the sections 3 and 4 are provided with ribs 7 and 8 respectively which extend longitudinally of the rail or transversely of the tie, and which are adapted to become embedded in the tie to prevent movement of the plate longitudinally thereon. The ribs are formed with a broad inclined bearing face 9 and a substantially vertical face 10 and the ribs on the two sections are inclined in opposite directions as shown clearly in Fig. 2. By this construction the plate is prevented from creeping in either direction longitudinally of the tie.

Formed upon the upper face of each of the sections 3 and 4 is a U-shaped member 11. These are formed integrally with the sections and are attached thereto at their outer ends adjacent the edges of the plate. The members 11 extend upwardly and in wardly and are formed with bearing faces 12 on their inner ends which impinge against the web of the rail, the flange of the rail resting between the upper face of the plate and the under face of the members 11. 13 and 14 indicate spike holes provided in the sections 3 and 4 respectively which are arranged between the arms of the members 11 in order that said members shall protect the spikes from the wheels of derailed cars.

It is obvious that with a plate as described the rail will be firmly clamped and that the greater the Weight or strain on the rail the tighter the clamping action will be. Furthermore, creeping of the plate is entirely prevented and spreading of the rails in a large measure obviated. Also should a car become derailed the spikes will be protected from the wheels and thereby injury to the track prevented.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A tie plate comprising a rectangular body portion divided diagonally into two similar sections, the diagonal abutting edges being provided with a plurality of interlocking and parallel members extending longitudinally of the plate and the under faces of said sections being provided with inclined ribs, the ribs on the two sections being inclined in opposite directions, substantially as described. c

2. A tie plate comprising a body portion divided diagonally into two similar sections, a plurality of parallel longitudinall extending interlocking members on the ia onal abutting edges, upwardly and inwardly projecting U-shaped members on said sections adapted to extend over the flange of a rail and impinge against the web thereof, and said sections being provided with spike holes between the arms of said U-shaped members, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
