RAILWAY-TIE.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed January 31, 1917. Serial N 0. 145,700.

To all whom it may concern:

Be it known that 1, WILLIAM P. DAY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

This invention comprehends certain new and useful improvements in railway ties, and relates particularly to that type known as the twin tie or rail support embodying spaced bars or members extending transversely of the rails, and plates connected to said members and extending longitudinally, in laterally spaced relation to each other, beneath the rails and riveted or otherwise operatively secured to the transversely ex tending members or bars.

The invention has for its primary ob ect an improved construction of twin t1e which may be very cheaply and easily manufactured out of standard stock and which will be positively and absolutely insulated, and prove entirely successful in use, especially in connection with steam traffic.

A further object of the invention is a tie of this type in which blocks are employed to directly support the rails, said blocks resting upon, but not rigidly secured to the plates hereinbefore mentioned, and belng carried loose thereon in order to allow the rails to take their natural wave as the train passes over the same.

The invention has for a further object, subsidiary to the foregoing, to provide a tie of this character in which the rail supporting and insulating blocks are prevented from creeping out of the trough of wh ch the said plates form the bottom, by abutting against or engaging the angle or other bars that constitute the transversely extending spaced members of the tie, the sides of said trough not only serving to prevent any sidewise movement of the blocks therein, but serving to support the plates across the tie.

A still further object of the invention is an improved construction of metallic tie in which the rail supporting blocks on each side of the track are held in spaced relation from each other by means of the ballast, whereby they will be prevented from creeping toward each other, while at the same time the blocks are permitted to move slightly with the traffic and may be readily changed and placed under the rails without disturbing the tie or the roadway, being The invention has for a still further object an improved construction and arrangement of rail supporting blocks whereby they are rendered interchangeable, being square in cross-section so that they may be turned over from time to time as they wear, this operation being capable of easy accomplishment owing to the fact that the blocks are not secured to the plates upon which they rest, and are only secured to the rails by spikes or the like, as hereinbefore specified.

Another object of the invention is an improved construction of twin tie in which the plates which support the blocks and also indirectly support the rails, are bent down at their side edges in order to produce a tamping area and to receive and maintain the ballast and which, with the angle bars or the like that form the transversely extending members, and the interposed and laterally spaced longitudinally extending angle or other bars riveted to the plates, form therewith troughs to receive and hold the blocks, in the manner hereinbefore indicated. Theshape of these plates, besides anchoring the ballast, also allows the tie to take a small deflection as the train passes over the tie, the tamping area of the track being carried longitudinally with the rail and the load being carried longitudinally and all possibility of the track becoming center-bound being precluded.

Another object of the invention is an improved twin tie wherein the construction and arrangement of the parts give the laborers easy access or space for the tamping operation and in addition thereto permit the ballast to be removed with a very small amount of work. The downwardly bent portions of the plates hereinbefore referred to prohibit any motion of the track during the operation of the train and insure that the plates will absolutely anchor the track in the roadbed and all liability of the tie lifting up out of the bed when the trains run over the same being obviated.

A still further object of the invention is a tie of this character in which the down-' wardly bent side edges of the plates produce between the latter and the bars that constitute the sides of the trough, spaces for drainage which feature, as is manifest, possesses advantages, particularly in aconstruction where wooden rail supporting blocks are employed.

And the invention also aims to generally improve devices of this class so as to render them more useful and commercially desirable.

WVith these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter more fullydescribe and claim.

Fora full understanding of the invention, reference' is to be had to the following description and accompanying drawing, in Which Figure 1 is a perspective view of-a twin tie embodying the improvements of my invention, the blocks being omitted at one side of the .tie,

Fig. 2 is a longitudinal sectional view of a portion of a track embodying the improvements,

Fig. 3 is a transverse sectional view through the tie, and c Fig. 1 is a detail plan view of one of the plates.

Corresponding and like parts are referred to in the following description and designated in all of the views of the accompany ing drawing by like reference characters.

Referring .to the drawing, the numeral 1 designates longitudinally spaced members which extend transversely of the track rails and which, in the present embodiment of the invention, are composed of angle bars, as shown, with .the angles facing upward and toward each otherthat is, with the horizontally disposed members projecting toward each other as clearly illustrated in the drawing; and 2 designates the plates which are secured to and upon the horizontally eX- tending portions of the angle bars 1, preferably by rivets asshown. 3 designates angle bars that extend longitudinally in laterally spaced relation to each other, upon the plates- 2 at or near the'side edges of the latter, and are riveted to said plates and preferably also to the bars 1, these angle bars 3 being preferably disposed in such position that their verticalmembers face or confront each other and their horizontal members project outwardly or away from each other.

The plates 2 and the bars 3 and those portions of the bars 1 which extend between the bars 8, constitute troughs, as is evident, and in these troughs are blocks 1 preferably of wood, said blocks being designed to rest upon the plates '2 and to directly support the rails, being secured to the latter by spikes or similar fastening devices, as desired. It is-to be particularly noted that the blocks 1 arenot secured to the plates 2 but are relatively loose therein and they are spaced from 'eaohother, as shown, whereby the ballast their side edges to form laterally and downwardly eX-tendingflanges 5, the lower edge of each flange being curved downwardly from its ends toward its middle, as shown, and the flanges extending from one terminal portion of the'plate to the other terminal portion thereof with the lower edges of the flanges ly-ing substantially parallel to each other and to the longitudinal axis of the plate. These flanges not only make a tamping area and serve to anchor the ballast, but they allow the tie .to slightly rock or take a small deflection as the train passes over, and furthermore-serve,

in connection with .the ballast which extends over, above and around them, to prohibit any motion of the track during the operation of the train, and positively prevent the tie from lifting out of its bed when the trains operate over the Same.

From the foregoing description intconnection with the accompanying drawing, it will be seen that I have provided a Very practical, durable and efficient construction of twin tie which will fulfil or attain all of the objects hereinbefore set forth, and which can be very easily and cheaply manufactured. The downwardly bent side portions of the plate 2 which constitute the flanges 5 produce at the sides of the trough and underneath the bars 3, longitudinally elongated spaces .6 which constitute drainage openings.

Preferably the blocks 4 are square in cross section, whereby they may he turned over from time to time as they are found more or less worn.

While the accompanying drawing. illustrates what I believe to be the preferred embodiment of my invention, it is to be understood that the invention is not limited thereto but that various changes may be made in the construction, arrangements and proportions of the parts without departing from the scope of the invention as claimed.

Having thus-described myinivention, what is claimed, is:

.1. A tie of v he character-described, comprising spaced members, plates secured to said members and extending longitudinally from one to the other at the ends thereof, bars extending longitudinally on said plates and connected thereto at the side edges thereof, and rail supporting means-138 resting loosely on said plates between said bars, as and for the purpose set forth.

2. A tie of the character described comprising spaced members, plates secured thereto and extending longitudinally from one member to the other, rail supporting blocks resting loosely upon said plates and the end blocks abutting against said members, for the purpose specified, and means for preventing the lateral movement of said blocks.

3. A railway tie of the character described, comprising spaced members, plates extending longitudinally and connected to said members in laterally spaced relation to each other, rail supporting blocks resting loosely on said plates and the end blocks abutting against said members, for the purpose specified, and bars extending longitudinally on said plates and connected thereto at the side edges thereof and engaging said blocks whereby to prevent any lateral movement of the same, the side edges of said plates being bent downward to form flanges and to also form drainage openings underneath said bars.

4. A railway tie of the character de scribed, comprising spaced angle members, flat plates secured to said members at the ends thereof and extending from one memher to the other, angle bars connected to said plates and extending longitudinally at the side edges thereof, said side edges being bent downward to form flanges that are curved downwardly from their ends toward the middle and the side edges of the bars extending substantially parallel to each other and to the longitudinal axes of the plates, said flanges producing openings beneath said angle bars, and wooden blocks mounted loosely upon said plates between said bars and engaged by the latter, the end blocks being engaged by the angle mem bers, as and for the purpose set forth.

5. A railway tie of the character described, comprising angle members spaced from each other, plates extending from one angle member to the other and connected thereto, said plates forming the bottom of troughs and the ends of the angle members forming the ends of said troughs, bars secured to said plates and forming the sides of the troughs, and rail supporting blocks loosely supported in said troughs, the end blocks adapted to abut against the ends of the troughs and the sides of the troughs preventing any lateral movement of said blocks.

In testimony whereof I aflix my signature in the presence of two witnesses.
