RAI LWAY-T RACK STRUCTU RE.
SPECIFICATION forming part of Letters Patent No. 517,277', dated March 27, 1894.
Application tied oaber 1s, 1 89s.
{zen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Railway-Track Structures, of which the following is a specication.
vThe object of my invention is to provide a permanent way for railways which, while practically indestructible, will compare favorably in economy with road beds having ordinary wooden cross ties, both as regards cost of material and expense of laying.
In the accompanying drawingsz--Figure l is a transverse section of a street railway with permanent way constructed in accordance with my invention. Fig. 2, is a plan view of one of the rail supports and its rail fastenings; and Figs. 3 to 6, inclusive, are views illustrating certain modifications of the invention.
Although in the drawings Ihave shown my invention as applied to the road bed of a street railway, it should be understood that it is not limited thereto, but is also applicable to the formation of permanent way for railways of every class.
In the drawings A A represent the opposite rails of the track, each rail being mounted upon a foundation consisting primarily of a block B of artificial stone, cement, concrete or the like, said block having a Vmetal cap plate a which is firmly united to the block by means of a pair of depending diagonal yokes b embedded in the block and riveted or otherwise secured to said cap plate ot. The cap plates are perforated for the passage of bolts d the heads of which'are embedded in the blocks B, the bolts on the inner sides of the track also passing through openings near the ends of a tie bar D which extends across the `road bed from one block to the other and thus serves to properly space the blocks B to accord with the desired gage of track and prevent any spreading or other lateral displacement of the same, said tie bar also serving to properly and accurately gage the rails A of the track by reason of the fact that the ends of said tie bar abut against the inner edges of the base flanges of said rails as shown in Fig. 1.
The rails are secured in position vertically by means of clamps f retained by nuts applied to the upper ends of the bolts d, a slot- Serial No. 488,030. (No model.)
ted filling block g, interposed between the cap plate a and theouter clamp platef, serving as a bearing for the outer edge of the base iange of the rail.
Between the base flange of each rail and the cap plate a of the foundation block is interposed a pad or cushion. 'm preferably of paper, which serves not only to provide a semi-elastic base for the rail,but also to deaden the noise which might otherwise be caused by the contact of the base of the rail with the metal plate.
The blocks B with their cap plate, tying yokes and bolts can be readily formed by pouring the artificial stone or cement composition into a box or mold in which said cap plates and yokes have been previously placed, the box or mold being removed as soon as the block has become set, so that the same mold is available for forming a large number of blocks.
The base of each blockB is tapered slightly at each side so thatwhen an opening approximating the proper depth has been dug in the road bed the block B can be used as a rammer until it has been caused to firmly seat itself in the'base of the excavation, and at the proper distance below the desired road level, the earth being, if desired, tamped under the edges of the block in case these portions are not firmly seated as the result of the ramming operation. t
Although the construction shown in Fig. l is to be preferred in most cases, various moditieations of such structure may be adopted within the scope of my invention, for instance, the cap plate a may have side flanges with inwardly projecting tongues for engaging with the block B and locking the cap plate thereto, as shown in Fig. 3 for instance, or the plate may be locked to the block by means of a central bolt having a hooked end or head embedded in the block, as shown in Fig. 4:, or the cap may, in some cases, be dispensed with eni tirely and the bolt-s may engage with a plate wholly embedded within the block as shown in Fig. 5, or a bolt may be embedded in the block, as shown in Fig. 6, the bolts in all cases being firmly united to the block so as to be undetachable and difcult to loosen.
Y In some cases a continuous longitudinal mass of artificial stone or cement may be formed beneath each rail and adapted to a longitudinal trench formed in the road bed, and such construction is included in the term block as used in the claims, although the detached blocks are preferred because they provide a foundation having ample stability with an expenditure of less material and with a less amount of excavation than would be involved in the use of the longitudinal trench with its contained bed of cement.
A road bed constructed in accordance with my invention is practically indestructible, While its cost compares favorably with that of an ordinary road bed having wooden cross ties which require to be frequently renewed.
Having thus described my invention, I claim and desire to secu re by Letters Patent- 1. The combination in a road bed for railways, of the rail, the foundation block of artilicial stone or cement, clamping devices securing the rail to said foundation block, and means whereby said clamping devices are firmly and immovably united to said foundation block, substantially as specified.
2. The combination in a road bed for railways, of the rail, the foundation block of artilicial stone or cement, clamping devices whereby the rail is secured to said foundation block, and a plate to which said clamping de vices are vertically confined, said plate being irmly and immovably secured to the foundation block, substantially as specilied.
3. The combination in a road bed for railways, of the rail, the foundation block of artificial stone or cement, the cap plate mounted upon said block, means for rmly and immovably uniting said cap plate to the foundation block, and rail clamping devices having securing bolts passing through said cap plate and having heads on the under side of the same, substantially as speciiied.
4. The combination in a road bed for railways, of the rail, the foundation block of artiticial stone or cement, the cap plate mounted upon said block, diagonal yokes secured to said cap plate and embedded in the foundation block, and rail clamping devices conned to said cap plate, substantially as specitied.
5. The combination in a road bed for railways, of the opposite rails, foundation blocks of artificial stone or cement, clamping devices for securing the rails to said blocks, securing bolts immovably confined to said blocks and tie bars adapted to the inner clamp bolts and serving as a means of spacing both the foundation blocks and the rails, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
