ASSIGNOB TO THE EYMON CROSSING COMPANY,
A. COBPQILATIOH OF OHIO.
RAILROAD-CROSSING.
Application filed Iu nc 10,
7?) all whom it may concern:
Be it known th.t I, Brnox E. \Vxnsox, a citizen 'of the United States residhgg at Marion, in the county or Marion and tate of Ohio, have invented a new and useful Railroad-Crossing, of which the following is a specification.
This invention is a cross-over device for intersecting tracks of railways.
One of the objects of the invention is to provide a cross-over device of simplean economical construction by means of which cars may pass across the rails of either of the intersecting tracks without creating the jar, noise and clatter incident to crossings now in general use. A further object is to provide means whereby the intersection blocks of the cross-over device may be conveniently manipulated and constructed to permit of the ready disengagement of the parts for repairs .and renewal without necessitating the raising of the base or otherwise disturbing the roadbed.
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying a top plan view illustratin device constructed in acco once with the invention. Figs. 2 and 3 are sectional views taken at right angles to each other on the lines 2-2 and 3-3 respeetively,Fig. 1,illustrating the shiftable intersection blocks. Fig. 4 is a detail view illustrating the connection between an intersection block and its actuating rod.
Referring to the drawing, 10 designates a base provided with crossover rails 11 an 12, intersecting each other at up roxilnately right angles as shown in the rawing, although the angle may be varied. Each ews'sdrawing Figure 1 is a cross-over over rail is provided with a groove for'theflange of the car wheel, and at the points of intersection, said rails are provided with extensions 14 so dis iosed as to form angular ru'cs a-s. Coiipcrahng with the extensions 14 to complete the recesses are rails having branches 15 and 16 connected by an angular portion, the branches 15 forming extensions ofthe rails 11 and the branches 16 forming extensions for the rails 12. Located within the ieccsscs formed by the extensions 14 are intersection or cross-over blocks 17 free to slide within the recesses, and provided with cam receiving lugs 18 which project through Specification of Letters latent.
Patented Nov. 11, 1919.
1919. Serial No. scams slots in the base 10. 'Each block is provided with one straight edge 19 to bridge the space between a rail 11 and a branch 15, and a correspondin edge 20 to bridge the space between a. ran 12 and a branch 16.
The means illustrated for shifting the blocks 17 consists of two bars 21. passed through and guided by suitable openings in the base 10, and each having an ofi'set portion 22 to provide a two-edged cam portion which is engaged by a cam receiving lug 18 of one of the blocks 17. The bars are guided in their longitudinal movement in any suitable manner, and may be shifted in any desired way, the action being to shift the intersection blocks 17 so that one edge 19 or the other edge 20 of each block is selectively caused to aline itself .with its rail 11 and branch 15 or its rail 12 and branch 16 as may be required.
The bars 21 are preferably shifted by' a construction such as illustrated in Letters Patent 967.179 to J. H. Eymon, dated August 16th, 1910, consisting of a three armed lever pivoted at 24, and having two of its arms slotted to engagtzpins on the bars. The third arm is connec y means of a 24 with a suitable operating device.
The construction above described is very similar to that disclosed in the patent to l'lymon above referred to. The construction of said patent, while efficient in operation. is open to the disadvantage that the operating liar-i cannot be disconnected from the intersection blocks without raisin the base upon which the parts are mounts and otherwise disturbing the roadbed. This objection is overcome in thepresent invention bg making the ofl'set cam portion 22 of eac .operailng bar 21 of substantially greater width than the main portion of the bar, and making the bar in two sections so connec at the points 25 (by nuts and bolts, for instance) as to permit the earn section to be readily separated from the other section. The width of the opening in the cam lug 18 'is much greater than the width of the bar 21 beyond either end of the cam portion 22. By reason of this arran ment, t e bar may be moved so as to entire y withdraw the cam portion 22 from the opening in said lug, and because the poition of the bar 21 beyond said opening is much narrower than the opening, ample clearance is provided tn permit th portion of the bar to be drawn straight through the lug 18, so that the block 17 may be raised without disturbing the base or the surroundin roadbed.
Having t us explained the nature of the invention and described an operative mannor of constructing and using the same, al-
- though without attempting to set forth all of the forms in which it ma be made, or allof the forms of its use w at is claimed is:
1. A railroad crossing of the character described comprising a, base, intersect-in cross-over rails carried by said base an provided at their oints of intersection with recesses, slideble intersection blocks located in said and each having edges positioned to selectively prolong the intcrsectin rails formin the recess in which it is placecfi each block aving a cam receiving lug extending through the base, operating bars having angularly disposed cam ortions engaging the respective lugs, an means for actuating said bars to shift the lugs, said cam portions of the bars being materially its intersecting bioclz to permit tic latter to be raised.
e2. A railroad crossing of the character described comprising a base, intersecting cross-over rails carried by said base and provided at their points of intersection with recesses, slidablc intersection blocks located in said recesses and each having edges positioned to selectively prolong the intersectin" rails formin the recess in which it is placed: each block iaving a cam receiving lug extending through the base, operating bars having angula-rly disposed cam portions extending beneath the base and engaging the respective In S, and means for actuating said bars to s lift the lugs, said bars and lugs having complcmental means whereby the burs m-a' be disengaged from the lugs to permit t 1e blocks to be raised.

In testimony whereof I have hereunto set my hand.
