TROLLEY-I-IANGER.

Specification of Letters Patent.

Patented J an. 9, 1912.

Application filed June 21, 1910, Serial No. 568,232.

To all whom it may concern.

Be it known that I, RoYnnN O. CoUcI-I, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Trolley-Hangers, of which the following 1s a specification. V

The present invention relates to hangers for trolley wires and has for its purpose to provide a device of that character having means whereby the wire engaging members are secured to the wire through a means which simultaneously secures the wire engaging members to their own supporting means; and the arrangement of these parts is such that they may be easily separated for the removal and insertion of the wire.

A further object of the invention is to provide wire engaging elements having means adapting them to fit on any standard hanger to which end the same are provided with neck portions having threaded sections and which, when united, provide effective means for securing the wire engaging elements to a supporting bolt.

The invention further contemplates the construction of a hanger of the above type, which is particularly adapted to catenary work.

The invention is shown in its preferred and modified structures in the accompanying drawings, wherein,

Figure l is a side elevation of a hanger embodying my invention; Fig. 2 is a vertical central section of the same; Fig. 3 is an end view of a hanger, partly in section and partly in elevation, showing an adapter ring for any standard hanger.

1 is a malleable iron or stamped'steel shell provided with a boss 2 on its top tapped to fit standard bolts, the tap terminating in an undercut groove 3 in which the head of a bolt may be seated. Instead of the boss, the shell can be made for span wire suspension or with a fiat oval base, whereby it may be secured to a mine roof or timbers by means of lag screws. The lower edge of the shell is provided with a series of damp ing fingers 4.

5 is a porcelain, glass or other suitable insulator which is pressed into the shell and held firmly therein by pressing down over it the fingers 4 of the shell. The porcelain is provided with the water-shed 6.

7 is a bolt, the head of which is seated in a recess 8 formed in the top of the POIOQ-f lain insulator, and 9 is insulating material secured'in said recess above the head of the bolt. This bolt extends through the in-f;

lower ends to clamp a conductor wire havmg the cross section of the figure 8. These clamps have a swell 14 about midway their length, on which are formed seats 15 adapt- 'ed to receive respectively the head of the bolt 16 and the nut 17. The upper ends of the clampingjaws 12 and 13 are flat as at 18 to adapt them to fit snugly against the lower face of the .porcelain insulator 5, while' the under faces 19 are formed on a bevel corresponding to the bevel of the upper face of the ring 11.

The jaws l2 and 13 are fitted on each side of the conductor wire and around the bolt 7, whereupon the bolt 16 is passed through the jaws and the jaws are drawn together by means of the nut 17 The angle of the bevel face 19 on the ring 11 and the angle 10 on the upper end of the jaws being the same, the jaws slide on said ring 11 and are forced in the space between the ring 11 and the lower face of the porcelain or other insulating substance 5 with the action of a wedge, so that in tightening or clamping the jaws on the trolley wire by screwing up the nut on the bolt 16, the bevel ring 11 causes the jaws to seat firmly between it and the insulator 5 and likewise pulls down on the bolt 7, so that all the parts of the hanger and clamp are firmly locked in position, preventing all wear and jar due to loose parts.

From the above, it will be seen that a hanger constructed according to my invention is simple in construction, cheap to manufacture has great heat resisting qualities, and has a maximum strength. The low height of the hanger and clamp makes it especially valuable in mining where there are low veins. In addition to these features,

the present invention is particularly adapted for the purpose specified by reason of the absence of the usual intricate joints on such structures, which are subject to rust or corrosion; and the means for assembling the wire engaging elements disclosed herein afford perfect alinement of the trolley wire at all times since from the very manner in 1. In a trolley wire hanger, the combination of the shell and insulating block secured in said shell, and a bolt secured in said insulating block and depending therefrom, of a wedging ring secured on said bolt and conductor wire clamping jaws, a bevel face on said jaws to engage with the wedging ring between the ring and block, and means to draw the jaws together to force the jaws against the insulating block, whereby to secure the several parts in firm relation to each other.

2. In a trolley wire hanger, the combination with a bolt, insulating material secured around said bolt, said bolt depending below the insulating material, of a ring secured on said bolt and-having an upper cam face and jaws having cam faces on the upper ends of said jaws, whereby when the jaws are clamped together the cam face on said ring forces the ends of the jaws up against the insulating material, thereby binding the several parts in firm relation to each other.

3. In a trolley wire hanger, the combination with a shell, an insulating block secured in said shell, and a bolt secured in said shell and depending therefrom, of a ring secured on said bolt and having an upper cam face,

conductor wire clamping jaws, the upper ends of which are provided with cam faces constructed to engage the cam face of said ring, and means to clamp said jaws together.

The foregoing specification signed at Micco, Florida, this 17th day of J une, 1910.
