SPECIFICATION forming part Of Letters Patent N0. 717,818, dated January 1903.

l Application filed March 8, 1902. Serial No. 97,247. (No modal.)

To @ZZ whom it may concern:

Beit known that I, JOHN HENRY CROWLEY, a citizen of the United States, residing at Duluth, in the countyV of St. Louis and State of Minnesota, have invented certain new -and useful Improvements in Railroad-Track Securers, of which the following is a full, clear, and exact description.

The object of myinvention is to provide a securer adapted to keep the rails of a railroadtrack from spreading apart or from turning or rolling.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar characters of Yreference indicate corresponding parts in all the views.

Figure l is a plan view of a railroad-track itted with my improved secu rer and showing one rail in position, Fig. 2 is a side view of the same, a rail being shown in cross-section; and Fig. 3 is a perspective view of the chair or tie-plate.

The chair or tie-plate l is made of suitable metal and has formed on its upper face two ribs 2, perpendicular thereto and parallel to each other. The space between these ribs is sufficient to admit a rail, and the height of said ribs is suflicient to allow them to be bent over to grip the base-flanges of said rail to form jaws. The ribs starting at alternate edges of the tie-plate l extend rand each terminates just short of the opposite edges, thus leaving spaces 3 on opposite sides of the rail and diagonally disposed to each other. In these spaces are located the spike-holes 4, through which spikes 5 are driven into the ties, the heads of said spikes being adapted to overlap and grip the base-flanges of the rails.

In laying a track the chairs or tie-plates 1 are spiked to the ties by spikes 6 driven` through holes 7, located at the four corners of said tie-plates. Before being spiked down the tie-plates are set to gage, the ribs 2 thereon running parallel to the direction of the track. The rails are then placed between these ribs .and secured by bending said ribs over onto the base-flanges of said rails. Then to make the track absolutely secure the spikes 5 are driven into the ties, their heads also gripping 5o said base-flanges. By this arrangement I have a very secure fastening device. The

rails are gripped by rm substantial jaws eX- tending virtually across the whole width of the plate, said rail at the same time not depending entirely upon said jaws for its fastening, but having additional security in the spikes 5, which also grip the rail and are driven directly into the tie. The described location of the spikes minimizes the danger of breaking or splitting the tie, gives a better- 6o distributed gripping area, and prevents that rapid deterioration of the tie due to the mutual proximity of a cluster of spikes.

As a precaution against spreading, especially on curves, I employ in connection with my tie-plate the tie-rods 8 and 9. In each tie-plate, near one end, is a slot l0,` running parallel to the ribs 2. The metal between said slot and the adjacent edge of the/tieplate'is shaped to form an arched member 11, 7o leaving an' archway l2 just large enough to admit the shank of the tie-rods 8 and 9. The tie-plates are placed on the ties with said arched members facing the center line of the track. Beforespiking down thetie-plates the 7 5 heads 13 ofV each pair of tie-rods are slipped under the arch-pieces ll and into the slots 10 of the respective tie-plates placed on opposite sides of the track. The ends of each pair of rods S 9 are threaded right and left, respec- 8o tively, and meet near the centerof the track in the turnbnckles 14. After the track has been set to gage and properly spiked and gripped these turnbuckles are operated to take up all slack, and a lock-nut 15 is screwed 85 up against each turnbuckle to keep it from working loose.

My tie-plate can be easily applied to a track already built by prying up the rails sufdciently to allow said plates to be slipped bego tween Vsaid rails and the ties, when they can be secured in the manner already described.

The advantages of my form of tie-plate will be particularly appreciated when it is necessary to shim under the rails. On account of the jaws which grip the rails the tie-plates will come up with said rails when the latter are lifted, and the shims can be placed under the tie-plates without disturbing the ties.

Having thus described my invention, I loo claim as new and desire to secure by Letters Patent- 1. A tie-plate having parallel continuous ribs extending nearly across plate and between which a rail may be placed and secured by bending down said ribs over the baseilanges of said rail, to form clamping-jaws.

2. A tie-plate having ribs thereon approximately perpendicular to said plate, and extending from alternate edges thereof, and each terminating short of the edge opposite that from which it starts, said ribs being of a height suciently greater than the baselianges of a rail to allow them to be bent over and to clamp said flanges.

3. A tie-plate having spike-holes disposed diagonally and spaced transverselya distance, to leave a rail-seat therebetween, the said holes being adjacent to opposite edges of the plate, the said plate also having bendable ribs rising from the upper surface a height suilcient to be bent over onto the rail-flanges, the said ribs extending from opposite edges to points adjacent to the mentioned spikeholes, and lying in line with said holes.

4. A tie-plate adapted to receive near each of its four corners spikes for securing said plate, adapted also to receive one spike at each end of the tie-plate adjacent to the rail but on opposite sides thereof, said spikes being adapted to grip the base-flanges of the rail, said tie-plate having also ribs on each side of the rail running parallel thereto and extending clear across the surface of the tieplate except for spaces diagonally disposed at opposite edges of said tie-plate.

5. A rail-securer consisting of a plate having ribs or jaws thereon between which the rails may be placed and secured by bending down said jaws over the base-flanges of said rail, said plate also having a slot and arched member adapted respectively to receive and hold the head of a tie-rod.

6. A rail-securer consisting of a plate having ribs or jaws thereon between which the rails may be placed and secured by bending down said jaws over the base-flanges of said rails, said plate also having a slot and arched member adapted respectively to receive and hold the head of a tie-rod, in combination with said tie-rod.

7. In a railroad-track securer, tie-plates having jaws thereon adapted to grip the baseilanges of a rail, and also having slots and arched members adapted respectively to receive and hold the heads of tie-rods, in combination with tie-rods, means for'adjusting said tie-rods, and means for holding said rods in adjustment.

8. A tie-rod having a head at each end, in combination with tie-plates having slots for receiving said heads and openings to receive the tie-rod, said openings leading out through the under face of the plate and to said slots.

9. In a railroad-track securer, tie-plates adapted to receive near each of their four corners spikes for secu ring said plate, and adapted also to receive one spike at opposite edges of the plate adjacent to and on opposite sides of the rail near enough thereto to grip the base-llanges of said rail, said tie-plates having also ribs on each side of the rail parallel thereto, and of a height sufficiently greater than the base-danges thereof to allow them to be bent over and clamp said flanges, extending clear across said tie-plate except for a space at alternate ends of said plate, said tie-plates also having each a tie-slot and arched member adapted respectively to receive and hold the head of a tie-rod, in combination with tie-rod, means for adjusting said tie-rod, and a means for securing the rods so adjusted.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN HENRY CROWLEY.
