RAILROAD-TIE.`

SPECIFICATION forming' part of Letters Patent N0. 577,714, dated February 23, 1897.

Application filed September 4, 1896. Serial No. 604,826. (No model.)

To all` whom t may concern:

Be it known that I, BENJAMIN BRADLEY, Sr., of Bellefonte, in the county of Centre and State of Pennsylvania, have invented a new and useful Improvement in Railroad-Ties, of which the following is a specification.

My invention is an improvement in railroadties, and has for its objects, among others, to provide a durable and efficient tie the removable blocks or wearing parts of which can be readily replaced; and the invention consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinaft-er described, and pointed out in the claims.

In the drawings, Figure 1 is a top plan view of the frame. Fig. 2 is an end view of the frame. Fig. 3 is a side View thereof. Fig. 4 is a detail view of one form of rail-lock. Figs. 5, 6, and 7 are detail views of the bearingblocks. Fig. 8 is a top plan view of the tie with the rails in place, and Fig. 9 is an end view of the tie with the rails in place.

The tie is formed with a metallic frame llaving main plates A A, of angle-iron, steel, or the like, which plates are bent in or oset at ct near their ends, forming chambers B, in which the bearing-blocks are fitted and held. The base-wings a of the angle-plates A form seats for the base-plates D, which rest thereon and are riveted or bolted in position. These base-plates D are arranged in pairs, one pair for each rail, and are spaced apart, the rail resting above the space between them, thus securing the advantage incident to the use of a wood or similar bearing-block, insuring more elasticity for rolling-stock and neutralizing the rigidity of iron frame-bearings. At the inner edges of the inner baseplate of each pairI provide cross-bars E, connecting the main plates and forming the inner walls of the chambers for the bearingblocks and also bracing the main plates.

The bearing-blocks F, F, and G rest upon the base-plates and iit within the chambers B snugly between the main plates A A. The outer blocks F are inclined on their inner edges f and fit snugly between the cross-bars E and the offsets a. The block Gr is wedge shape and ts between the blocks F and is made longer than the blocks F, so its point may be cut o and it driven in from time to time to take up shrinkage. These wedgeblocks are held by the bars H, which connect the ends of the main plates, and these bars II may be set in from time to time to correspond with the adjustments of the Wedge-block, a

plurality of holes h being provided for thev bolts securing said bars H, so the latter can be set in as may be required. These blocks F and Gr project above the frame, so the rails will not bear upon the metal. tice make the blocks of wood, paper, grass, wood-pulp, cotton, or other substance suitable for the purpose.

The bearing-blocks, being made alike for the different Widths of ties, could be seasoned and painted before using, thusmaking them last longer, and when necessary such blocks can be readily replaced without removing the main portion or frame of the tie, the manipulation of the bearing-blocks being easily effected through the ends of the main frame, which can be opened by removing the crossbars II. The frame when in position and properly ballasted is practically indestructible.

The rail-locks I and J iit the outer and inner sides of the rails and are bolted to the plates A A, being provided with shoulders fi, resting on the upper edges of the said plates, as shown in Fig. 2. These locks I and J are hooked together at j and fit in the hollow of the rails, the outer locks I bearing snugly up against the under side of the ball of the rail, while the inner locks J hook iirmly over the base of the rails. Where these locks come opposite fish-plates, they must be formed accordingly, as will be understood from the lock at the right in Fig. 8. For narrow ties (or curves of railroad) the outside locks may be notched in the upper edge of the plate A with a lug K on the lock to enter the notch of the plate, as shown in Fig. 4.

It will be understood that my invention avoids the necessity of spikes and dispenses with their use.

By covering the frame With ballast expan- I may in prac- IOO Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. A tie comprising the metallic frame ha V- ing the main plates of angleiron the baseplates resting on the lower wings of said main plates and the bars connecting said main plates substantially as shown and described.

2. A tie comprising the frame having main plates provided near their ends with offsets extending at right angles to the direction of length of the tie and forming the outer end walls of the bearing-block chambers and with cross-bars forming the inner walls of said chambers and the bearing-blocks iitted in said chambers substantially as shown and described.

3. In atie the combination with the frame of the outer bearing-blocks, and the inner wedge-block such blocks havinginclined faces whereby the inner block may be set up to take up wear (be. substantially as shown and described.

4. A tie consisting of the frame having main plates of angle-iron and provided near their ends with offsets, the base-plates resting on the lower wings of the main plates, the crossbars connecting the main plates and forming the inner walls of the bearing-block chambers, the bearing-blocks in said chambers,

and the end cross-bars connecting the main plates all substantially as shown and described.

5. The combination of the tie-frame, the bearing-blocks fitted in and projecting above the tie-frame and the rail-locks secured to the tie-frame substantially as shown and described.

6. A tie composed of the metal frame, and the removable wear-blocks held in said frame and consisting` of the outer blocks and the inner wedge-blocks such blocks being arranged at their upper faces to support theA rail and the inner block being tapered and movable longitudinally in the direction of length of the tie whereby it may be set longitudinally without affecting the bearingplane for the base of the rail substantially as shown and described.

.'7. The combination of the tie-frame having a notch and the rail-locks hooked together and secured to the tie-frame one of such locks having a lug entering the notch of the tie-frame substantially as shown and described.
