WALTER R. SCOTT, OF BUFFALO, NEW YORK.

TROLLEYBREAKER.

SPECIFIQATION forming part of Letters Patent No. 538,390, dated April 30, 1895.

Application tiled December 19, 1894. vSerial lilo. 532.310. (No model.)

To all` whom i5 may concern:

Be it known that I, \VALTER R. SCOTT, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Trolley-Wire Connections, of which the following is a specification.

This invention relates to the hangers for supporting trolley wires and particularly to coupling hangers employed for uniting adjoining trolley wire sections.

My invention has for its object to provide the hanger with simple means for facilitating the attachment of the wires to the same.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, showing my improvements applied to an insulatinghanger whereby the ends of two trolleywire sections are connected. Fig. 2 is a top plan View of the saine. Figs. 3 and 4 are cross-sections thereof, on an enlarged scale, in lines 3 3 and e 4, Fig. l, respectively.

Like letters of reference refer to like parts in the several figures.

Referring to Figs. l to 4, A A represent the end pieces of the insulating hanger to which the adjacent ends of the trolley Wire sections B B are respective] y attached. Each of these end pieces is provided at its outer end with a longitudinal. eye or sleeve a through which theend portion of the adjacent Wire passes.

' c represents a pair of uprightlugs` or ears projecting from the upper side of the end piece a short distance in rear of the longitudinal eye ra, and separated by Ia space in which the wire is arranged. I

d 's are'movable transverse pin which passes v'through openings formed 'in said ears and i I f Yaround .whichthe end portion of the wire is pins cl and e are withdrawn from the openings of the parallel ears and the wire is passed through the longitudinal eye a and placed with its end portion between the parallel ears. The rear pin is then inserted in its openings in the ears and the wire is bent or doubled forwardly over said pin in the form of ahook as shown, after which the front pin is put iu place. The closedl longitiu'linal eye at the outer end ofthe end piece firmly and securely holds the Wire in place at this point while the pair of lugs and the transverse pins enable the end of the wire to be readily and conveniently attached to the end piece.

F is a bar or block of wood or other insulating material which connects the end pieces of the hanger. This bar is provided at each ond with a contracted portion f forming a shoulder f". 'lhe contracted portion f is seated in a socket g formed in an enlargement G on the inner side of the adjacentend piece and the shoulderf bears against the inner end of the end piece around the socket. 'lhe insulating bar is secured inthe sockets ofthe end pieces preferably bylongitudinal bolts g' which pass through the enlargements G and through longitudinal openings formed length wise in the end portion of the bar, as shown in the right hand portion of Fig. l. In fastening the end pieces of the insulating bar the screw'nut at the inner end of each bolt g is dropped 'into a lateral opening g2 of the bar which communicates with the inner end ofthe longitudinal opening and the bolt is then screwed into said nut, after which the outer nut of the bolt is tightened against the end of the enlargement. This mean of fastening the insulating bar tothe en pieces forms a Very strong and reliable connection between these parts and prevents the end pieces from becoming displaced on the insulating bar. The lower edges of the end pieces are substantially Hush with` the trolley wire.

H is a bar or rail of wood or other insulating material arranged between the inner ends vof the end pieces below the insulating bar F and having its lower edge'arranged flush with that of the end pieces of the connection s o as to form practically an unbroken continuation thereof. The ends of this rail are seated in sockets h formed at the inner ends of the end pieces below the sockets g, the ril 4being pret erzibly further secured in its sockets by transverse pins h. y

I represents n supporting yoke whereby the hanger is suspended from the usual cross wire J and Whichembraces the upper insulating barF. The yoke is provided at its top with n cross head K which terminates ilu hooks under which the cross wire engages, th`e`w'i'r being,r held in engagement with said hooks by defiectingits intermediate portion around the central boss of the yoke through which the fastening bolt 7o' of the cross head passes.

My improved means for connectingtlie ends of the wires to the/end pieces may also be used for connecting the sections of n trolley l wire which do not require to be' in'suia'ted, in

which cas''th'e two end tegrally. i

I claim as' my 'invention-g 1. A hunger or coupling having it its' end a'closed longitud-inni eye form'e'd" integ'rlly with the end piece of the bange'rorcoupling and adapted to receive a. wire", and provided in rear of said `integral eye with @fastening piecesV mafy be east indevice for `,the end of the wire,` substriii'tially as set forth.

2. Ahanger provided/with apar of upright ears separated by a veprice which receives the `provided with :i longitudinal eye formed in-l tegrally therewith a'nd adapted to receive a wire and having in rear of said eye a pair ot' upright ears sepa'jrzited by a. space which receives the end portion of the wir-e, .andrfront being bent around theV rebut-pin, aindjthe front substantially s'et forth.-

Wmiess my hand this 1on1 day or De'enber, 1891i. y y
