TROLLEY HANGER.
APPLICATION FILED JUNE 5.1915.

TROLLEY-HANGER.
To all whom it may concern Be it known that we, WILLIAM T. ROBIN- SON and CHARLES D. HYLToN, citizens of the United States, residing at Ethel, in the county of Logan and State of West Virginia, have invented certain new and useful Improvements in Trolley-Hangers, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to trolley hangers, and particularly trolley hangers for use in mines where the law provides that the trollley wires shall be protected.
The primary object of our invention is the provision of a trolley hanger so constructed that it may be readily fastened to the roof of a mine, and further so constructed that it will support parallel depending timber guards disposed on each side of the trolley wire. 7
A further object of the invention is to provide a trolley hanger of the character de scribed, so constructed as to protect trolley wires at overhead crossings in mines.
Other objects will appear in the course of the following description.
Our invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a top ulan view, diagrammatic in its nature, showing intersecting mine tracks and our trolley wire guard and hanger applied thereto; Fig. 2 is a sectional view of a portion of a mine roof showing the guards applied thereto, the guards being in elevation; Fig. 3 is a like View to Fig. 2 but showing the end of one of the guards; Fig. 4 is a top plan view of our improved hanger; Fig. 5 is a transverse sectional view of the hanger.
Referring to the drawings, and particularly to Fig. 5", it will be seen that our iniproved trolley hanger comprises a standard insulated bell 2 formed on its lower face with a socket 3 and with a depending stud bolt 4: adapted to engage with any standard trolley clamp, designated generally 5. Formed integral with the hell 2 and extending laterally in opposite directions therefrom are the yoke arms 6, these being downwardly curved at their ends, and formed with feet 7 which extend at right angles to the aXis of the bolt a, these feet being perforated for the passage of bolts 8. Carried by the bolts 8 and bearing against the un- Specification of Letters Patent.
Application filed. June 5, 1915.
Patented Sept. 7, i915.
Serial No. 32,399.
der face of the feet 7 are the guard boards or timbers 9. These timbers are preferably two by four, and the inner faces of the timbers are spaced from each other a distance of about nine inches. The timbers extend downward below the trolley wire. The hanger is provided in line with the bolt 4} with a screw threaded socket 10 adapted for the reception of a standard expansion bolt 11 which is insertible into the roof of the mine, this roof being designated A.
As illustrated in Fig. 2, the guard timbers 9 are used at overhead crossings in mines. The trolley wire, which is designated 12, is disposed to one side of the track B, as shown in plan view in Fig. 1, and where one track, as for instance C, intersects the track B, the trolley wire of track C will have to be carried across the track C to the trolley wire of track B. The guard boards are used to protect the trolley wire 12 of the track C where it crosses track B. Preferably, the timbers constituting the guard 9 or guard boards are made in two sections, spliced as at 13, by forming a scarfjoint onthe adjacent ends of the sections of the joints, the bolts 8 passing through this scarf joint as clearly shown in Fig. 9..
The hangers as above described are cheaply constructed, are applied as easily as an ordinary hanger, and thoroughly protect the trolley wires in accordance with the laws of the several States regarding the protection of trolley wires in mines. It will be seen that the guards may be readily applied or readily removed, and that inasmuch as these guards simply consist of two by four timbers there will be no difliculty in replacing them from time to time when necessary.
Having thus described our invention, what is claimed is:
1. A trolley hanger for mines comprising a yoke embodying oppositely disposed arms and a depending bell, the bell being provided with a stud bolt for engagement with a trolley clamp, the extremities of the arms being formed with perforated feet, guard timbers bearing against the under faces of the feet, and bolts passing upward through the guard timbers and through said feet.
2. A trolley hanger comprising a yoke embodying oppositely projecting arms and a bell, the bell being formed with a downwardly projecting stud bolt, the upper face of the yoke above the beii being formed with our signatures in the presence of two witan upwardly proJectlng screw threaded nesses. socket, the outer ends of the arms belng i WILLIAM T. ROBINSON. formed with feet, guard tlmbers disposed against said feet and depending therefrom, CHARLES HYLTON' and bolts passing through the guard tim- Witnesses: bers and through the feet. J. W. BUNTING,
In testimony whereof We hereunto affix J. B.
