RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent No. 249,707', dated November 15, 1881.

(No model.)

To all whom it may concern:

Be it known that I, FREDnIc G. WEIR, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Railroad- Crossings, of which the following is a specification.

My invention relates to that class of crossings which are constructed of rails.

Figure 1 is a plan of vmy invention. Fig. 2 is a sectional elevation on line .fr a', Fig. l. Fig. 3 is a sectional elevation on line y y, Fig. 1. Fig. 4 is a sectional elevation on line z z, Fig. 1., with corner-piece removed. Fig. 5 is a sectional plan of one of the corners of the cross ing, showing the arrangement of the anglearm plates for strengthening the rails where cut away.

In constructing the crossing I use for the foundation, as it were, two rails, A A, of sufficient length to permit of notching the heads at the gagewidth B of the track that is to cross it and reach outside ot it at either side, enough to permit ofthe solid bent rail cornerstrengthening pieces C and the sh-plates of the adjoining trackD being fastened to them. These two rails I use for the track that has the greatest service over it. After notching at B these two rails, I provide wrought-iron anglearm plates'E, with the arms F projecting outwardly from them. These angle-arm plates E are sufficiently long to reach across the cut through the head of the rails, and are firmly riveted or bolted through the web G, thereby restoring as far as possible the loss of strength kof material by the cutting away ofthe head of the rail to permitof the passage of the flanges of the wheels, and at the same time furnishing an angle-arm, F, to rivet or bolt to the interto the proper gage, I strengthen the structure by adding at the outside corners, las shown,

strengthening-angles (l or J, or both, formed from the same-sized rail as the body of the crossing itself, and I likewise form inside continuous guard and additional strengthening angles, K, also formed from the same-sized rail, bent at two corners and joined at the two others by strengthening-plates L, the whole system ot' rails being held apart, where necessary, by spacing-blocks M and bolted through the several sections of rails, as shown. Where necessary to protect the throat or the openings into the crossings that are not guarded by bended corner rails, I use short guards that are spaced away from the main rails and bolted to the spacing-blocks.

The object of this invention is to provide a stronger and more durable crossing without the use ot' the base-plates frequently used, and thereby furnish through the additional strengthening-corners, inside as well as outside, a sudiciently broad bearing to enable the crossing to be laid on the ordinary ties, in-

stead of the large and expensive timbers required in many cases, and, besides, making the crossing a more elastic portion of the road-bed than can be done with the use of plates under it.

It is obvious that different-sized rails from those used for the main tracks might be used; but the same size is preferable.

I have shown my improvement as applied to a right-angle crossing. It is obvious that it is equally adapted to any other required angle.

Having described myinvention,whatIclaim 1s l. A railroad-crossing constructed of two rails of a length greater than the gage of the intersecting track, Vand having notches cut through the heads of said rails to permit the passage of the ianges of the wheels on said intersecting track, said rails being strengthened by angle-arm plates reaching by said notches on either one or both sides of said rails sufciently to permit their being riveted or bolted to the webs of the said rails, substantially as specified.

2. A railroad-crossing constructed of two main rails notched through the heads to the gage of the track that is to cross it, and having its intersecting rails swaged upward, so that their bases shall rest on the top of the IOO flanges of the main rails, substantiallyas specitheir heads to the gage ot' said intersecting I5 fied. l track, and having its inside and outside cor- 3. A railroad-crossingr constructed of two ners strengthened bysolidly-bent cornersfrom main rails notched through the heads to the the same material as the body of the crossing,

5 gage of the track that is to cross it, each of said said strengthening corners also acting as rails having a strengthening-plate on one or guards, substantially as specified. zo both sides thereof at each notch, said plate In testimony wh'ereof Ihave hereunto set my having an arm-plate attached thereto and prohand in the presence of two subscribing witjecting therefrom at the required angle, to n esses.

1o which the intersecting rail is riveted or bolted substantially as specified. 7 FREDRH WEI' 4. A railroad-crossing constructed of two Witnesses: main rails of a length greater than the gage of EUGENE L. FIRNKoEss, the intersecting track, and notched through F. W'. BROWNE.
