Patented Dec. a, 1896.-

UNITED STATES PATENT OFFICE.

DANIEL GRUHLKEY, OF MARSEILLES, ILLINOIS, ASSIGNOR OF ONE-HALF TO WILLIAM H. GRUHLKEY, OF SAME PLACE. A

RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent No. 572,702, dated December 8, 1896.

Application led March 2 8, 18 9 6.

To all whom it may concern.:

Be it known that I, DANIEL GRUHLKEY, a citizen of the United States of America, residing at Marseilles, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Railroad- Crossings, of which the following is a specification, reference being had therein to the accompanying drawings and the letters of reference thereon, forming a part of this speciiication, in which- Figure l is a plan of the crossing. Fig. 2 is a side View of one of the sliding blocks of the swing-rails of the crossing-rails, and Fig.

3 is a side view of a portion of one of thei swing-rails and of one of the crossing-rails and a cross-section of one of the main rails.

This invention relates to certain improvements in railroad-crossings, which improvements are fully set forth and explained in the following specification and claim.

Referring to the drawings, A A represent the two main rails, which are unbroken where they are crossed by the cross tracks or rails. B represents swing-rails forming a section of the cross-rails between the main rails A and pivotall57 connected at their inner 'ends at a, from which pivotal point a the swingrails may swing, as indicated by the broken lines, so as to swing off;l from over the main rails. The cross-rails and said swing-rails are on a plane a little higher than the main rails, as shown in Fig. 3, so that the head of sliding blocks S traverse a rail R, as shown particularly in Fig. 2, and said rail is secured firmly to bed-plates L. In order that the said cranks may operate without obstruction, a

Serial No. 585,202. (No model.)

portion of the rail R and bed-plate-L are cut In operation the sliding blocks are caused i to move to or from each other by means of rotating shaft E by any means desired and not necessary to be shown,and thus the swingrails are swung on their pivotal centers a, as indicated by the broken lines, so as to form a crossing over the unbroken main rails, or turned off of the main rails, so a train can pass on the main rails. In Fig. l the swingrails are turned so as to form a crossing over the main unbroken rails. The sliding heads are shown connected with a double crank for sliding them, but they may be moved to swin g the swing-rails by any other desired means, and the crank-rod E may be operated by any means desired.

The swing-rails may swing back over the main rails, as shown in Fig. 1, and rest at their outer ends against a solid block or stop V, secured on the bed L, so as to prevent the car-wheels from spreadin g them apart at their free outer ends.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

In a railroad-crossing the combination of the unbroken main rails the cross-rails, the swing-rails forming a section of the cross-rails between the main rails and arranged` on a higher plane than the main rails so as to swing over them, the sliding heads and their guiderail, the rods for connecting the swingrails respectively with the sliding heads, and the means for reciprocating said sliding heads and swinging said swing-rails all arranged to operate substantially as and for the purpose set forth.
