RAILWAY-TIE.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed May 2, 1908. Serial No. 430,435.

To all whom it may concem:

Be it known that 1, JAMES LEAI-IY, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Railway-Ties, of which the following is a specification.

The object of this invention is to provide a cast steel railway tie of simple and substantial construction, which can be easily cast, and which is adapted to be securely and firmly embedded and anchored in the ballast of the track so that it will not move or creep endwise or longitudinally of the track.

In the accompanying drawings Figure 1 is a plan view of a tie embodying the inven tion. Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 3 is an elevation showing one end of the tie illustrated in Fig. 1. Figs. at and 5 are, respectively, plan and side views showing another embodiment of the invention.

The tie is preferably made of cast steel and in a single casting and it comprises a base 6 having end entrance pockets formed at its ends to receive the bearing blocks 7 for the rail 8. The bearing block pocket is formed by an inclined end wall 9 and two side walls 10, and the end wall may be located at the inner end of the pocket, as shown in Figs. 1 and 3, or at the outer end of the pocket, or the end wall may be located at the inner end of one pocket and at the outer end of the other pocket, as desired. The bearing block may be secured in the pocket in any suitable manner as by means of a locking plate 11 provided with a lateral flange 11 and adapted to be seated in a transverse groove 12 in the base of the tie. The locking plate is secured to the tie by a bolt 13 and cotter pin 14 or other suitable means.

In Figs. 4 and 5 I have shown the pocket formed by a short end wall 9 and the two side walls 10, and the block secured in place by a bolt 15 extending transversely through the sides 10. This bolt 15 may be located in any suitable position to secure the block in the pocket and, if desired, the block, which is shown rectangular in shape in Figs. 4: and 5,may be wedge-shaped, as shown in Figs. 1 and 3, and the end wall 9 and bolt 15 correspondingly arranged to secure the block in the pocket.

The tie may be provided adjacent to the pockets with lateral flanges 16 which are preferably provided with openings 16 to receive ballast. A transverse rib 17 is arranged on the underside of the tie beneath each pocket and side flanges 18 extend preferably throughout the length of the tie between the transverse ribs 17. These side flanges are also preferably provided with openings 18 to receive ballast although both the lateral flanges and the side flanges may be made without openings, as shown in Figs. 4 and 5.

The tie is constructed to taper from each pocket to its middle, the sides being illclined preferably on straight lines so that the tie is narrowest at its middle. The side flanges 18 on the base of the tie form a channel to receive the ballast and by reason of the taper of this channel from the pockets to the middle of the tie and the embedment of the tie in the ballast movement or creeping of the tie endwise will be entirely avoided. The transverse ribs 17 may be provided as a further precaution against the movement of the tie but these ribs may be omitted as shown in Figs. 4: and 5, if desired. The ribs and flanges on the underside of the tie also prevent the tie from moving lengthwise of the track and the side flanges 16 broaden the bearing of the tie on the track bed to prevent tilting and to maintain the tie in proper fixed position. The base of the tie may be provided with openings 19 for the same purpose as the openings 16 and 18 are provided (Fig. 1).

My improved tie is designed so that it can be easily made of steel in a single casting and it is strengthened lengthwise and transversely by the flanges to withstand shocks and jars to which it may be subjected in service.

The tie is constructed to be firmly and securely anchored in the ballast so that it will not creep endwise of the tie or longitudinally of the track.

-What I claim and desire to secure by Letters Patent is:

l. A cast steel railway tie. comprising a base having pockets thereon adjacent to its ends to receive rail bearing blocks and tapered from said pockets to its middle, trans verse ribs on the underside of the base beneath the pockets, lateral flanges on the base opposite said pockets, and depending flanges at the side edges of the base between said transverse ribs.

2. A cast steel railway tie comprising a base having pockets thereon to receive rail bearing blocks, said base projecting beyond the pockets, transverse ribs on the underside of the base beneath the pockets, lateral flanges on the base opposite said pockets, and depending flanges at the side edges of the base and extending from the rib beneath one pocket to the rlb beneath the other pocket, said base being tapered from said pockets to its middle, and said base on each side of the pockets and s'aidlateral flanges and depending flanges having openings therein to recive the track ballast.

3. A cast steel railway tie having end entrance pockets to receive rail bearing blocks and groove in its base at the open end of each pocket, a locking plate to enter said groove to secure the block in the pocket, and means for fastening the locking plate in place. 1
