Application led April 1, 1911. Serial No. 618,434.

To all whom it may concern:

Be it known that l, JOHN T. CLARK, a citizen of the United States, residing at Provo city, in the county of Utah and State of Utah, have invented certain new and useful Improvements in Railway-Ties and F asteners, of which the following is a specification.

The purpose of my invention is to provide a railway tie, and a fastener to secure the rails thereon, which will have the sustaining surface necessary for the rails, and one having the central portion so formed as to prevent lateral movement of the tie.

A further object is to provide such a tie and fastener therefor as will prevent lateral and longitudinal displacement of the rails, and any tendency to bend at the joint of the rails, and also to provide a perfectly insulated rail for use in the block signal system.

A further object is to provide a railway tie and fastener on, and by which the rails may be secured and removed within less time than now is required.

Other objects and advantages will appear from the following specifications and drawings, forming a part hereof.

In said drawings similar figures of reference indicate like parts throughout the several figures.

Figure l is a side elevation of one end of the tie, with the rail and parts of the insulation in section. Fig. 2 is a vertical longitudinal section of one end of the tie and fastener, on line a a; Fig. 4. Fig. 3 is a plan of one end of the tie and a central portion of a rail thereon. Fig. 4 is a plan of one end of the tie, with a portion of two rails at the joint, also a central portion of one of the bridge fish-plates. Fig. 5 is an end elevation of three of the ties, and a side elevation of the bridge fish-plates, parts cut away. Fig. 6 is a plan of the tie, with rails and insulation removed. Fig. 7 is a plan of one end of the tie, with the straps removed, parts cut away.

My tie is made of sheet metal, bent to form an upturned channel l. Near each end a section of the sides of said channel is cut away, and metal straps 2, are transversely placed therein, forming a partial cover for said channel l, and between said straps 2, the sides of said channel 1, are further cut away. The metal portion of the bottom of said channel l has H-shaped cuts or slits 3 therein, and the inner or tongue parts of said cuts are each bent downward at right angles to the bottom of the tie, thus forming depending lugs 3', the purpose being to embed said lugs 3 in the road-bed, and prevent lateral displacement of the tie. Said straps 2 have vertical slots 4 cut therethrough, preferably at an angle cf about 45 degrees from the longitudinal of the tie. Within the covered portions of the'tie are placed short blocks of wood or other fibrous material 5, the upper side of which extends above the edges of the deeper cuts in the sides of said channel. Over the said blocks 5, and within said covered portions of the tie, are placed metal rail plates G, having vertical slots 7 cut therethrough, preferably at an angle of about 45 degrees from the longitudinal axis of the tie, and vertically alined with the said slots 4 in the straps 2. rlhe purposes of said blocks of wood are; first, to provide a certain amount of resiliency or cushion effect under the rails A, second, to hold the bolt or spike that is to be driven through the slots 4 and 7 and into the said block of wood. At each end of each of said blocks 5 and within the covered portion of the tie, and between t-he said rail plates 6 andthe said straps 2 is driven one portion of a bracketshaped metal wedge 8, having the inserting edge thereof tapered to engage and slide on the upper side of the flange of the rail. The vertical portion of said bracket-shaped wedge 8 covers the outer end of said wooden block, and is made the same length as the distance between the upper side of the bottom of said channel l and the lower side of said straps 2. Cut through the horizontal portion of each of said bracket-shaped wedges 8, are slots 9, preferably at an angle of about 22 degrees from the longitudinal, and so alined with the said slots 4 and 7, that when the said wedges are being driven into place, some part of said slot 9 will be in vertical alinementwith said slots 4 and 7. lf desired, two of said series of slots 4, 7 and 9 may be placed on one side of the rail. When a bolt or spike 10, having a flanged head 11, and with the squared portion l2 adjacent to said flange, is inserted through the said slots 4, 7 and 9the wedge 8 cannot be removed until t-he said bolt is withdrawn. To prevent the said bolts or spikes 10 from being jarred from slots 4, 7 and 9 by the vibrations caused by passing trains, the lower end of the said bolt is driven a short distance into the said wooden block 5. The squared portion 12 of the said bolt 10 is of a length equal to the thickness of said straps 2, and each side of the square is the same width as the width of the said slots 4 andv 7. This prevents any tendency of the said bolt 10 to roll. To prevent water, either rain or melted snow from entering through the said slots and injuring said blocks 5, a washer 17 is carried on each of said bolts 5, shaped to cover the said slot 4.

Placed on the outside and at the juncture of two rails A, and bolted thereto by the bolts 15 is the bridge fish-plate 13. The upper side of said bridge fish-plate is placed fiush with the tread of the rails. The said bridge fish-plate is made of length suflicient to transversely cross or c'over three of my ties, when the ties are in place on the road bed. At each tie, and held by the bolts 15, is placed a brace-block 14, having a shoulder 16 cut lnear each end, forming a depending lug, which fits over the edge of the said channel 1. rlhe purpose being that when said bridge fish-plate and the brace-blocks are inzposition and firmly bolted to the rails, any longitudinal movement of the rails will be prevented. 1f it is desired to insulate the rails, a strip of insulating material 18, is placed under the rail, the bridge fish-plate and the brace-block, and over the tie and other parts of the fastener. The said bridge fish-plate, covering at it does three ties, prevents any vertical movement of the ends of the rails, when the train passes over that partof the track, and the consequent breaking ofthe insulation. The different angles of the slots 4, 7 and 9 form a different opening or hole for said bolt or block at each position of the said wedge, as it is inserted or withdrawn thus enabling me to fasten the said wedge at any position, and to form a spring tension clamp for rails of various weights, or thickness, or width of flanges, and to take up any shrinkage from wear or otherwise, of said wooden blocks 5. Also I provide a hole for the spike or bolt that is adjustable in position.

Having thus described my invention, I desire to secure by Letters Patent and claim:
