LOCKING- HANGER.

SPECIFICATION forming are of Letters Patent No. 729,440, dated May 26, 1903. Application filed October 31,1902. Serial No. 129,584. (No model.)

To all whom/ it may concern:

Be it known that 1, Louis Srnrivenncnaa citizen of the United States, and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and State of New York,

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi-l cate corresponding parts in both figures.

Figure 1 is a side elevation of my hanger, and Fig. 2 is a vertical section upon the line 2 2 of Fig. 1 looking in the directionof the arrow.

The cap 1, of insulating material, is rigidly connected with a bolt 2, provided witha head 3, this head and a portion of the bolt being preferably embodied in the cap, as indicated The bolt 2 is further provided with" Y I the bolt 2 is once set in a predetermined poin Fig. 2. an enlarged threaded portion 4: and with a comparatively small threaded portion 5. A

metallic yoke 6 of the usual construction is 7 provided with a conical opening 7 and is engaged by a substantially conical insulating member 8, provided with a central passage 9, whereby the same is given a somewhat annular form.

A member 10 for supporting the wire or ca ble is integrally mounted upon a web portion 12, and thereby integrally connected with a socket 11, which is threaded internally and screwed upon the threaded portion 5 of the bolt. A lock-nut 13 is threaded internally, as shown, and screwed upon the larger threaded portion 4 of the bolt.

My invention is used as follows: The yoke 6 being mounted in the usual manner, the bolt 2 is inserted therein from the top, the cap 1 being centrally disposed, as indicated in Fig. 2. The cone 8 is next fitted concentric to the bolt and to the opening 7 of the yoke 6. The locknut 13 is now passed upward over the lower end of the bolt and is screwed upon the en.- larged portion 4 thereof until the upper surface of the'nut is forced rigidly against the lower surface of the cone 8, thereby forcing the cap 1 and the bolt 2 downward and the cone 8 upward, .or the nut is dropped over the socket of the clip. The clip is then screwed fast on the lower end of the bolt, and the nut is thenscrewed tightlyon the larger threaded portion of the bolt, thereby clamping the cone, yoke, and cap firmly together. It will be observed that when the parts mentioned 1 are in the position just described a composite structure of great strength is formed. The ear is next mounted in position, which is done by 3 simply screwing the threaded socket 11 upon the comparatively small threaded portion 5 at the lower end of the bolt. It will be observed thatthe screw-fastening between the socket 11' and the threaded portion 5 of the bolt is entirely independent of the screw-fastening between thelock-nut 13 and the larger threaded. portion .4: of the bolt; The result is that the'lock-nut 13 may be loosened or tightened at will for the purpose of adjustment or for any other purpose and that as an independ ent proposition the ear may he removed and replaced at will. 7

By means of the device just described if sition and locked rigidly in that position by means of the lock-nut 13 the ear when taken off and replaced will always arrange itself in a predetermined position-say, for instance, at right angles to the general direction of the yoke 6. The operative need not hesitate to take oif the ear, as the same can always be replaced so as to occupy its original position. If through any usage the threads are worn and the ear works into a position awry, the same can be easily corrected by loosening the lock-nut l3, adjusting the cap 1 relatively to the yoke 6, and then tightening the locknut 13.

It will be observed thatv the lock-nut 13 is slightly larger than the socket 11. This is for the purpose of enabling the lock-nut 13 to be loosened or tightened while the socket 11 is in position and without disturbing the same. In other words, the lock-nut 13 can be removed from the threaded portion 4 and allowed to drop downward a short distance the bolt.

' ulation.

In the old style of hangers of similar construction the cap, yoke, and cone are held together by screwing the clip or ear onto the threaded end of the bolt embedded in the cap portion. 0 wing to the swaying of the trolleypole and to many other causes the parts soon become loosened, and finally the cap twists itself free from the threaded socket of the clip, and in consequence the line drops and interferes with the proper work of the current.

One object of my invention is to lock the cap, yoke, and cone firmly together, irrespective of the clip. In consequence the swaying of the trolley-pole cannotloosen the hanger parts, whereby loss of time is avoided and much trouble and expense are prevented.

I do not limit myself to the particular form of device above described, as many other forms may be employed all coming Within the scope of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A hanger, comprising an insulating-cap, provided with a depending member, a meiallic yoke engaging said cap, an ear provided with mechanism for engaging said depending member, a cone of insulating material for engaging said member, and a locking device for engaging said member and said cone.

2. A hanger, comprising a cap of insulating material provided with a depending member, an ear detachably connected with said de pending member, a metallic yoke engaging said cap, and means independent of said ear for securing said cap and said yoke rigidly together.

A hanger, comprising a cap of insulating material provided with a depending member, a cone of insulating material for engaging said member, an ear detachably connected with said depending member, a metallic yoke engaging said cap and said cone, and mech anism independent of said ear for securing said cap, said cone and said yoke rigidly together.

4. A hanger, comprising a cap of insulating material provided with a depending member, a metallic yoke engaging said cap, and means for detachably securing said cap and said yoke together, and an ear for engaging said depending member.

5. A hanger, comprising a cap of insulating material provided with a depending screw, a metallic yoke engaging said cap, an ear provided with a threaded socket for engaging said screw, and locking mechanism independentof said socket for securing said cap and said yoke rigidly together.

6. A hanger, comprising a cap of insulating material provided with a depending screw, a metallic yoke engaging said cap, an ear pro vided with a threaded socket for engaging said screw, and means, controllable at will and independent of said socket, for securing said cap and said yoke together.

7. A hanger, comprising a cap of insulating material provided with a'depending screw, a metallic yoke engaging said cap, an ear provided with a threaded socket for engaging said screw, and a locking device, controllable at will, for securing said cap and said yoke together and releasing the same Without disturbing the position of said screw relatively to said ear. 8. Ahanger, comprising a cap of insulating material provided with a depending member, a yoke engaging said cap, an annular cone of insulating material encircling said member, means for locking said yoke, said cap and said cone together, and an ear provided with mechanism for securing the same upon said depending member.

10. A hanger, comprising a cap of insulating material provided with a depending bolt, said bolt being provided with a threaded portion, a yoke for supporting said cap, an annular cone encircling said bolt, a nut mount ed upon said threaded portion and free to en gage said cone, an ear, and means for detachably securing the ear upon said bolt.

12. A hanger, comprising a cap provided with a bolt, said bolt having a plurality of distinct threaded portions, a metallic yoke for supporting said cap, an annular conical member encircling said bolt and engaging said yoke, a lock-nut engaging one of said threaded threaded socket engaging the smaller of said.

threaded portions.

14. As an article of manufacture, a central member for supporting a trolley-ear, comprising a cap of insulating material and a bolt connected therewith, said bolt being provided with a plurality of distinct portions for engaging a locking device and a clip-socket respectively,

15. As an article of' manufacture, a central member for supporting a trolley-ear, comprising a cap of insulating material, and a bolt connected therewith, saidbolt being provided with a threaded cylindrical portion for en gaging a clip-socket, and with a comparatively large threaded portion for engaging a locknut.
