CROSSING FOR TROLLEY CONDUCTORS.

Application filed December My invention relates to overhead-trolley line construction For electric railways and particularly to adjustable crossings there for having deflector bars.

One object of my invention is to provide a device of the above-mentioned character in which the body members and deflector bars may be readily adjusted to suit any angle at which the overhead line conductors cross each other.

Another object of my invention is to provide a device of light weight and one in which the ends of the deflector bars will not project very far beyond the body members at any time.

In practicing my invention, I provide a crossing comprising two pivotally connected body members and deflector bars that may be attached to the body members at points near the center of the crossing when the body members cross each other at a wide angle. but which may be moved to positions near the ends o1 the body members when they cross each other at a small angle.

My invention will be more readily understood by reference to the accompanying drawing, in which the single figure is a bot-- tom plan view of a crossing and deflector bars embodying my invention, two positions being indicated.

Referring to the drawing, the construction therein shown comprises two main or body members 1 and 2 that cross each other approximately at right angles and are pivotally connected at their center by a pin 3, the projecting head of which acts as a stud for guiding the wheels or shoes of trolley collectors as they pass over the crossing, in accordance with a familiar practice. Each of the body members 1 and '2 is provided with suitable ribs 4 for further guiding the trolley collector wheels or shoes over the crossing and may also be provided with bayonet approach members 5 at each end for gripping and holding trolley conductors, (not shown).

In order to reduce the danger of a misalined trolley collector from becoming lodged between the body members 1 and 2 of the crossing, guard members or deflector bars 6 are placed across the V-shaped openings therebetween. One end of each deflector bar 6 is pivotally secured by a bolt 7 to an apertured lug 8 on the body member 1 2a. 1925. Serial No. 78,140.

near the center of the crossing, and its other end is located in a suitable recess 9 in the body member 2.

The body members 1. and 2 are shown in full lines as crossing each other pl'ttCtltlfllly at right angles, and the deflector bars 6 are located near the center of the crossing. The body member 1 is further provided with another set of apertured lugs 10 that are respectively located farther away from the center than the corresponding lugs 8, and the body member 2 is also provided with a corresponding set of recesses 11 near its ends, the lugs and recesses being adapted to re ccive and hold the ends of the deflector bars 6 when the body members 1 and 2 are erected so that they cross each other at a small angle, for example, as shown by the dotted lines.

Inasmuch as the deflector bars 6 may thus be readily shifted from an inner position in the crossing to an outer position, depending upon the angle at which the crossing members are placed in service, it will not be necessary to make them more than approximately one-halt as long as the deflector bars heretofore used in adjustable crossings. The use of short deflector bars will also decrease the weightof the crossing, which is of material consequence in overhead line co11- struction, and the ends of the bars that pass through the recesses 11 will not project to such degree as to be liable to catch trolley collectors if they become misalined and lodge against the side of the crossing.

lVhile I have shown and described a particular form of my invention, I desire it to be understood that changes may be effected therein without departing from its spirit and scope. as set forth in the appended claims.

I claim as my invention:

1. An adjustable crossing for trolley conductors comprising a deflector bar and two pivotally connected body members provided with a plurality of means for securing said deflector bar at various distances from the center of the crossing.

2. An adjustable crossing for trolley conductors comprising a deflector bar and two pivotally connected body members provided with means for securing said deflector bar near the center of the crossing when the body members cross each other at large angles and having means for securing the deflector bar near their ends when they cross at small angles.

3. An adjustable crossing for trolley conductors comprising a plurality of pivotally connected body members, and a deflector bar attached to the body members, each of said body members being provided with a plurality of means to which one end of the deflector bar may be attached and having a plurality of means adapted to receive the other end of the deflector bar.

4. An adjustable crossing for trolley conductors comprising a plurality of body members pivotally connected at one point. and a deflector bar adopted to connect the body members at another point, each of said body members being provided with a plurality of apertured lugs to which one end of the deflector bar may be connected and having a plurality of recesses adapted to receive the other end of the deflector bar.

5. An adjustable crossing for trolley conductors comprising two pivotally connected body members and a plurality of interchangeable deflector bars adapted to be secured to the body members in different positions.

In testimony whereof, I have hereunto subscribed my name this 16th day of December, 1925.

WILLIAM SCHAAKE.
