"0 all whom t may concern: longitudinal curvilinear portion 6 which is Be it known that I, BENJAMIN B. BETTs, of adapted to tit upon one sidev of the trolleythe city of St. Louis, State of Missouri, have wire 7. The portion 6 extends into an upinvented certain new and useful Improvewardly and outwardly flaring side plate S, the

ments in Trolley-Wire Hangers, of which the upper outline of which is tapering from the 55 following is a full, clear, and exact descripends upwardly to a rectangular portion 9, tion, reference being had to the accolnpanyfrom which depends a plate following the ing drawings, forming a part hereof. saine outline as the plate 8, and both of said My invention relates to improvements in sides S and 10 forming, together with connect- Io trolley wire hangers and consists in the ing portions l1 a chain ber 12 as shown in Fig. 6o novel arrangement and combination of parts, 3. The lower edge 13 of the side 10 is not the as will be more fully hereinafter described same in form as the curvilinear portion 6, and designated in the claims. but at a point above the lower terminus of The object of my invention is to improve said portion 6, is provided with an inwardly upon a class of articles,known as trolley-wire projecting portion 14. Into thechamber12 and 65 hangers, and in connection with certain parts providing the other half of the clamping surforms a secure fastening for the same by face to the trolley-wire, is disposed a remov- Ineans of which it is suspended from poles or ablejaw 5,thelongitudinal portion 15 of which cross-wires. is the same in cross section as the portion 6 of 2c In the drawings: Figure 1, is a detail elethe plate 8. The upper part 16 of the jaw is 70 vation of a trolley-wire held in position by substantially the same outline as the interior means of my invention. Fig. 2 is a perspecofthe chamber 12,to prevent anylongitudinal tive view of my improved clamp.

Fig. 8 is a sectional view of the jaw 5, and are adapted to engage the with parts brokenaway of an additional modiconductor 7. It will also be perceived that fied means of manipulating the clamping-jaw. if some means for keeping the upper portion 85 Fig. 9 is a perspective view of the wedge and 16 of the jaw 5 away from the side 8 and tolocking-wireas usedin the construction shown ward the sidel 10 the trolley-wire 7 will be in Figs. 1, 2, 3 and 4. tightly clamped Y between the faces 18 and Referring to the drawings: As is usual in 19 and to this end I have designed several 4o street railway constructions, supporting posts means. 90

1 are made use of and located at determinate In Fig. 9 is shown a view of a wedge 20, distances apart. The poles 1 are preferably the sides alone of which are tapered, all of located upon both sides of the street or roadthe taper being upon one side of same with way, in alignment and connected by crossthe opposite side rounded oft'. The wedge 2O wires, from which depend insulation clampis provided in its upper surface with agroove 95 holders 2. To these holders 2are adapted to 2l connecting near the broad end of said be secured trolley-clamps 3, constructed afwedge with an opening 22 extending downter the method ot' my-invention. The clamp wardly through the saine. In the manufac- 3 comprises a frame 4 and a removable adture, a wire 23 is placed in the opening 22 5o justable jaw 5. The portion 4 consists of a and then bent downwardly into the slot 21. 100

When said wedge is driven through openings 24 in the top 11 of said frame 4, the wire 23 is bent upwardly against said rectangular portion 9 as shown in Figs. 2 and 4, and this prevents the backing out of the wedge from between the upper end of the jaw 5 and the edges of the opening 24. This construction admits of the adaptation of my invention to different sizes of conductors, as the securance of the conductor depends upon the position of the Wedge 20, and the farther in that the wedge is driven, the closer together the curvilinear faces, 18 and 19 are brought. The rectangular portion 9 is surmounted by a portion 25 provided with an opening 26, by means of which the same is secured in the clampholder 2.

In Figs. 5 and 7 is shown a modified manner of adjusting the jaw 5. The plate 8 is provided near the rectangular portion 9 with a horizontal slot and with a projecting lug 27 located in alignment with the lower edge of said slot and projecting outwardly from said plate. Pivoted to said plate 27 is an eccentric cam 28 having a manipulating handle or arm 29. The main portion of the eccentric 28 extends into the chamber 12 and engages the portion 15 of the jaw 5. When the cam is in position as shown by heavy lines in Fig. 7 the jaw 5 is necessarily held in a rigid position, but when said arm 29 is drawn into position as shown by dotted lines in said figure, the eccentric is out of engagement with the jaw 5 and the same is therefore in position for adjustrnent.

In Fig. 8 is shown a modification of the means for securing the jaw 5 and consists in providing a thickened portion 30 upon the plate 8 and placing a screw-threaded opening therein and through said plate 8. An adjustable set screw 51 operated in said screwthreaded opening, determines the adjustment of the jaw 5. The frame 4 is notched or recessed at its ends, as shown at 32, to accommodate the end edges 33 of the jaw 5.

The description above given and the annexed drawings will facilitate a clear understanding of the case and the details will readily be seen, and as a whole the hanger embodies features which combine to make it an important; and valuable improvement.

All of the parts of my invention are made of some suitable and cast metal and owing to their relation with each other will enable the adjustment of the jaws over the wire when desired.

Having fully described my invention, what I claim is 1. As an improvement in trolley-wire hangers, the combination, with a casing comprising side plates one of which being provided With a longitudinal curvilinear r portion, the other side being provided with an inturned edge located above said portion, of an adjustable jaw comprising a shank disposed within the casing and provided at its lower end with a longitudinal groove adapted to receive said inturned edge of the casing side, and a curvi linear portion carried by said shank and corresponding to and arranged reversely to the curvilinear portion of the casing, and means for adjusting the shank laterally within the casing; substantially as set forth.

2. As an improvement in trolley-wire hangers, the combination, with a casing provided with alstationary jaw and in its upper end with coincident slots, and an adjustable jaw provided with a shank disposed in said casing, of a wedge adapted to be received by said slots and adjust the movable jaw, and means for locking said wedge in position; substantially as set forth.

8. An improved trolley wire-hanger having a fixed jaw, an adjustable removable jaw, a wedge adapted to hold said adjustable jaw in a clamping relation over an electrical conductor, and a wire fitted in said wedge and adapted to be bent upwardly against the fixed jaw, when said Wedge is in position, substantially as set forth.

4. An improved trolley wire-hanger having a fixed jaw provided with a projecting perforated lug by means of which said hanger is secured to an insulated holder, said fixed jaw provided with an interior chamber, the sides of which converge toward each other at the bottom, the longitudinalcurvilinear lower edge of said xed jaw adapted to fit upon the wire, said fixed jaw provided with slots, a removable adjustable jaw adapted to tit into said interior chamber in said fixed jaw, a wedge adapted to project through said slots between the fixed and removable jaw-plates. and hold the lower curvilinear end of said removable jaw over the other side of said wire, substantially as set forth.

5. An improved trolley wire-hanger having a wedge adapted to clamp a removable jaw located within a xed jaw over an electrica. conductor, said Wedge tapered upon one side and provided in its upper surface with a slot terminating in a vertical opening in said wedge, an L-shaped piece of Wire adapted to normally rest in said slot and opening, and the free end of which is adapted to be bent upwardly, against the fixed jaw and hold the wedge in a determined position to secure the lower curvilinear clamping face of said adjustable jaw against the electrical conductor, substantially as set forth.

In testimony whereof I affix my signaturein presence of two witnesses.

BENJAMIN B. BE'lTS.
