RAILROAD-TIE AND PLATE.

Specification of Letters Patent.

Patented Apr. :22, 1913.

Application filed November's, 1912. Serial No. 730,256.

To all whom it may concern:

Be it known that I, CHARLES H. Wssr, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Railroad-Ties and Plates, of which the following is a specification.

This invention relates to a combined railway tie and clamping plate. I

The object of the invention is to hold securely the rails and also to prevent sagging of the rails due to the rotting of the wooden ties. At the same time it is found desirable to employ a certain amount of wood in connection with a railway tie, as this material possesses certain properties not found in ties constructed entirely of concrete, or of metal. A solid concrete 'tiedoes notpossess the elasticity requisite in a perfect tie and under heavy pounding is liable to split. A solid metal tie is subject to a conslderable amount of contraction and expansion be- 5 In the accompanying drawings, Figure 1' is a plan view. of a portion of a track Withmy improved ties and clamps in use. Fig. 2 is a longitudinal section through one of said ties, the rails being shown 'in transverse section. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig.4 is a section on the.line 44 of Fig. -1.. Fig. 5 is a'detail perspective view of one of the clamping plates.

In constructing my device, I employ a metallic trough or pan 1, said pan haying a length, width, and depth substantially those of the ordinary wooden tie. Within and at each end of said trough is arranged a wooden block 2, and similar blocks 3 are arranged transversely within the trough and at a distance from the blocks 2 equal to the width of a rail base. The distance between the blocks 2 and 3 should not be less than that mentioned and is preferably slightly greater, so that the base of the rail does not overlap the'said blocks. The space 'ed to fit over the rail base.

the plate 8 are bent downwardly forming between n blocks is filled' in'with concrete as mdlcated at- 4. The longitudinal central portion of the tie, that isbetween the blocks 3, is also filled in with concrete as shown-at 5, the said concrete having embeddedtherein a cross shaped metallic reinforcing bar 6, the ends of which bear upon the adjacent faces of the blocks 3. The

rails 7 rest upon the concrete blocks 4 formed between the blocks 2 and 3. In

' order to clamp the rails in position I employ plates 8, which upon one side carry a laterally and upwardly extendingflange 9 adapt- The ends. of

perforated. ears-10. These plates fit upon the wooden'blocks 2 and 3' and the cars 10 extend .down over the outer faces of the trough 1. Both the locks and the sides of the trough are 'suita y perforated, theper- 'forations of the cars- 10 registering with those of the trough and blocks. The. plates 8 are locked in position by means of bolts '11 which'pass through the ears, the sides of the trough and the wooden blocks, suitable nuts 12 working upon the threaded ends of the bolts. These bolts prevent any movement of the plates in a direction at right angles to the rail, and the ears prevent any longitudinal movement of the plates. As

these plates rest upon wooden blocks the bolts and nuts are not subject to the'jars and vibrations to which they would be subjected if there was a continuous metallic surface between the said bolts and nuts and the top rails. Furthermore, by employing wooden blocks as shown, I provide a tie which is especially adapted for use where electric wires are run alongside the track for the purpose of operating switches and signals. Where metallic ties have been tested it has been found that there is more or less danger of a short circuit being formed through the tie itself. The wooden blocks therefore form suitable insulating surfaces to which the electric conductors may be safely secured.

What I claim is: 1'. A device of the kind described, comprising a metallic troufgh, wooden blocks 2. -A device of the kind described comprising a metal trough, wooden blocks arranged therein, concrete blocks molded in said trough, and spacing the wooden blocks apart, said trough and the wooden blocks having alining perforations, and rail-clamping plates provided with depending perforatedearsfthe'perforations of the ears being adapted to register with those of the and spaced-from the endfblocks,a distance equal to the width of a rail base, concrete.

blocks arranged between the wooden blocks at each end of the tron h, respectively, a concrete blockarranged 1n the trough and extending from-one of the second mentioned blocks to the other, a metallic reinforcement in' the last mentioned concrete block, said reinforcement bearing at its ends upon adjacent-faces of the second mentioned wooden blocks, rail clamping lates having depending ears extending ownwardlv over the sides of the trough, and suitable bolts for securing said ears to said trough, said bolts 30 passing through, said wooden blocks.
