RAILWAY-CROSSING.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed April 2, 1910. Serial N0. 552,972.

To all whom it may concern:

Be it known that I, JOHN A. STRALEY, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Railway-Crossing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, ref erence being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to railway crossings, and has for its object the provision of simple and improved means for shifting the rail sections at the crossing of two lines to alternately and selectively open or close one line and simultaneously close or open the other line, which means is easy and efficient in its operation, inexpensive in its construction and maintenance, and composed of a minimum number of parts.

The invention is fully described in the following specification, and a preferred embodiment of the same illustrated in the accompanying drawings, in which,

Figure l is a plan of a crossing embodying the features of my invention. Fig. 2 is a sect-ion of the same on the line 02 w in Fig. 1. Fig. 3 is a section on the line 1 y in Fig. 1, and Fig. at is a perspective view of one of the parts of the invention.

Referring to the drawings, 1 designates the fixed tracks or rails running in one direction, and 2 the fixed tracks or rails of the crossing line, all of which at and adjacent the point of crossing are mounted upon a suitable base frame 3, shown in the present instance as being formed of I-beams. Each rail of a track is connected between the rails of the other track by two movable rail sections at, 4, which are supported by the frame 3 and, when in longitudinal alinement, adapted to fill the space between the rails of the crossing track.

Each rail section 4 is mounted adjacent its outer end for longitudinal sliding movements in a rail-chair or member 5, which is pivoted for horizontal rotary movements upon the frame 3, and has flanges 6 adapted to overlap the base flanges of the section to slidingly hold the section to the chair. In the present instance the rail-chairs are shown as having pivot-studs 6 working Within registering sockets in the frame 3 (see Fig. 3) and as being rotatably held to the frame by fingers 7, which project from such frame and hook over the rounded edges of the chairs, as indicated.

The inner ends of each set of rail sections 4 are pivotally attached at their other sides in any suitable manner to the opposite ends of a. cross-arm 8 of a bar or draft member 9, which projects inwardly between the inner ends of the sections. The inner end of such bar is provided with a laterally angled arm 10 having a longitudinally-extending slot 11 therein which parallels the rails of the track with which it is associated. The arms 10 of the opposing bars 9, which are adapted to overlap each other, extend in opposite directions from their respective bars and their slots 11 vertically register with the like slots in the arms 10 attached to the rail sections at of the other track.

J ournaled in a frame part 3 centrally of the several rail sections 4 is a short vertical shaft 12, which carries a cross-arm or bar 13 at its upper end beneath the plane of the bars or draft-members 9. Studs lt project upwardly from the ends of the cross-arm l3 and each works within the registering slots 11 of two of the bars 9, one of which projects from a set of rail sections 4 of one track while the other projects from the set of sections of the other track toward which the arm 10 of the first bar projects, as shown. A nut 15 is shown as being threaded to the outer end of each stud lt to retain the asso ciated bars 9 in engagement therewith.

Upon a turning of the cross-arm 13 in the proper direction, outward longitudinal movements are imparted to the bars 9 of two of the opposed sets of rail sections to move the sections of such sets into alining positions to close the associated track, and inward movements are imparted to the other bars 9 to move the opposed sets of sections 4: of the other track out of alining positions, as indi cated, and upon giving the arm 13 a reverse quarter turn the above action is reversed. The bars 9 are guided for true horizontal movements by fins 16 projecting downwardly therefrom and working in longitudinal slots 17 provided in the subjacent frame parts 3"-, which parallel such bars.

18 designates a horizontally-disposed lever, which is fulcrumed beneath one of the slotted frame parts 3 and is provided at one end with a segmental series of teeth 19, which mesh with a pinion 20 on the shaft 12, and at its other end with a segmental series of teeth 21 in mesh with the teeth of a reciprocatory rack-bar 22. This rack-bar is mounted for horizontal reciprocatory movements on the inner side of a portion of the frame 3 beneath one of the sets of rail sections at and has one end extended without the line of the other track and provided at such end with a vertical slot 23 in which the wrist-pin 24: of a crank-arm 25 works. The crank-arm 25 is carried at the end of a rockshaft 26, which is journaled in a part of the frame 3 beneath the plane of the track and in a bearing part 3 secured to the frame An operating lever 27 is carried by the shaft 26, and is secured in adjusted position by a pin 28 passing through registering apertures in such lever and a plate 29 fixed to the bear ing part 3 30 designates stop flanges which are secured to the frame part 3 in position to overlap the outer base flanges of the rail sections 4 at their inner ends and to coact therewith to limit the outward or closing movements of such sections, thus preventing their inner ends from being thrown outwardly beyond a line in longitudinal alinement with the rail of the associated track.

The operation of my invention is as follows. Supposing the track to be set as indicated in the drawings with the rail sections 4: of the track 2 closed to provide continuous rails for such track, such rail sections may be thrown to open position and the rail sections of the other track thrown to closed position with their respective rails by simply throwing the operating lever 27 to the opposite side of the shaft 26 from that shown in the drawings thus imparting substantially a half rotation to such shaft. As the shaft 26 is rotated in this manner the wrist-pin 2st carried by the crank arm 25 of such shaft works within the slot 23 in the end of the rack-bar 22 and eifects a longitudinal movement of such bar to oscillate the lever 18 due to the outer tooth end of such lever meshing with such rack. Upon a rocking of this lever its inner pivoted end which is in mesh with the pinion 20 on the shaft 12 imparts a quarter rotation to such pinion and shaft to cause the studs l-Lt to be moved a quarter of a revolution about such shaft and to work within the slots 11 in the inner connected ends of the respectively engaged bars 9 to draw the outwardly projected bars 9 inwardly to break or open the rail sections at of the track 2 and at the same time to force the other set of opposed bars 9 outwardly to move the attached rail sections 4: to close the track 1 for the passage of a train thereover. As the rail sections t are moved to open the track such sections have slight inward sliding movements in the rail chairs or members 5 to retract the outer ends of the rail sections from the continuous rails to provide a space for the passage of the flange to the car wheel.

It is thus apparent that I have provided a simple and inexpensive form of crossing, the movable rail sections of which are positively moved to alternately and selectively open or close one line of the track and simultaneously close or open the other line.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.
