Application filed. May 1a, 1912. serial No. 698,347.

To all whom it may concern:

Be it lmown' that L'WADE H. Wmmne TON, a citizen of the United States, residing use in railway crossings.

-' 5 of labor and time rg ui 3 The main object of the present invention is to provide means for retaining the upper member or members of the crossing in position and for withstanding the lateral and vertical strains incident to the use of the crossing by means of engaging parts on said upper and lower members which are formed integrally with said members, thereby dispensing with the use of bolts or like devices for such purpose, and obviating the liability of loosening or displacing the said members. by reason of failure or loosening of such bolts or like devices.

A further object of the invention is to i provide means for connecting the upper and lower members of the crossing in such mannor as to reduce to a minimum the amount red for removing or replacing the crossmg. Another object of the invention is torreduce the cost of the renewal of the crossing to a minimum.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate embodiments of the invention, and referring thereto: Figure 1 is a plan of the crossing. Fig. 2 is a vertical section of one side of the crossing, showin one form of construction of the upper an lower members. i

The crossing comprises a'lower member 1 which may be cast or forged of iron or steel and is secured in permanent position at the location of the crossing, being, for exam I? secured to ties or embedded in a cement -or otherwise fixed ri dl'y in position. '1 is lower member may e'formed of integral casting or forging, or of any desired number of pieces secured together in any suitable manner, and may be providedwith a foot and ahead or top portion at at the top of the web 3, said top portion 4 being provided with flanges 5 and 6 at its edges, said flanges 5 and 6 extending upwardly and then inwardly to form grooves T and 8.

The top member comprises a tread rail 10 and a guard rail 11, said tread rail 10 being formed with a tread portion or head' 12 and with a foot portion 13 resting on' the top portion 4: of the bottom member, said foot portion 13. having a lateral extension or tongue 13 which extends and fits into the groove 7 of the bottom member. guard rail 11 is provided with afoot portion 14 having a laterally extending flange or tongue 14 fitting in the groove 8 of the bottom member. Furthermore the two rails 10 and 11 fit or interlock together by longitudinal tongue and groove joint, one of said rails being formed with a longitudinal rojection l7 and the other member wit a groove 17 fitting said projection. When the rails arefitted together in this manner, the effect of their own weight and of the weight of the train passing over them is to press the rails 10' and 11 more firmly in position on the bottom member. In order, however, to avoid any. liability of the rails jumping out of position by reason of vibration throu h movement ofthe cars or vehicles over t e same, suitable connectingnieans such as pins 19 may be used, extending through said rails and held 1n wedgesor keys 20.

The lower member 1 is apermanent fixture in the roadbed' and in case' the crossing position by "is tobe repaired, it is only necessary to remove and renew the upper member, this be, ing done by driving out the wedges 20 and then tipping rail members 10 and "11 up-' into tight engagement with said grooves.
