INSULATOR.

To-al'l whom fitfmafgco'awem:

Be it known that we, MAX NEUBERT and Rnvivronn P.. Jones', citizens. of the United States, residing at Glen Jean', in the county of llayette andi Statey of West Virginia, have inventer-l1 new and: useful Insulator, of which the followingis a specification.

'lhis invention relates to sectional insulators for electric trolley' systems and has for' its object to." provide ai sectional? insulatoiathe-construction of which is such that' Athe trol'l'ey Wheel Will. remaiznin contact with' the .terminals oil the. insulator darin its passage over the latter' so that shoufl ..the

y will: be' ine a: position tio-start the motor.

A lfurther object ci the inventionA is to Vprevi-de ai section insulator the terminal contacts'o which are over-lapperilf` at the center of the insulator and! connected with' eachl other" by a switch -or bridge wire so that in event ci any disturbance on the' line the section' oi the conductor or linewre containing the insulator may be cut out or disconnected troni the rest of the line. y

' Further objects and advantages will ap- 'l'.iear'L in the follxiwing` description, it being` understood that various changes in form, 'proportions and' minor details of construction'. mar-y he resorted to within the scope of thefazppended-claims.

In the accompanying drawings forming; apart of this specication: Figure l is a side 'elevation of a section insulator constructed `in accordance with our invention. Fig. 2 'is a top plan view of the same'. 3 is a b ottonr plan View oi? the saine. Flg. 4: is a perspective view of one of the end pieces or contacts' detached. .Fi-g. 5- is atransverse Fig. 1.

parallel side walls

7 and 8 spaced apart to form anl intermediate socket 9 for the reception of a strip of, insulating material l0, said end` pieces being secured to the strip 10 by means of screws or similar fastening devices ll.

Each end piece is provided with a lonagiv udinal extension 12 having its lower face formed `with a longitudinal groove 13 for the reception of the adjacent end of the-line wire 14, there beinginclined grooves 15 piercing the extensions 12 and communicating with the longitudinal `frooves 13, as chown.

The line wire I4 mayA be or any desired r ross sectional formation and in the present instance is shown in the form of a figure right, the terminals of said line wires being extended within the grooves l5 and locked in contact with the end pieces by screws 0r :-in1ilar clamping devices 16.

The lower longitudinal edge of each end piece at the adjacent extension 13 is formed with a lip 17 adapted to be bent upwardly in engagement with the lower surface of the line wire" 14 thereby to forni a bridge piece and permit the ready passage of the trolley wheel over the base of the insulator.

The arms 9 of the end pieces are provided with reduced extensions 18 which over-lap at the'center of the insulating strip l() and ere providedy with curved 'tcrniil'ials 19 disposed' one on each side ot' the insulating strip 10, as shown.

Secured to one oi' the terminals iS) is a clip 20 in which is pivotally n'iountod at 21 thev adjacent end of a switch 22, the opposite und of which is adapted to contact with a similar clip mounted on the saine side of the insulator as the clip 2t.

lrI"he switch 22v is preferably in the form of a flat longitudinal bar the free end of which is provided with an operating` handle 24 by means of which the switch may be moved. to operative and inoperative positions thereby to connect the contacts or end 'pieces 5 and withthe line wire or to disconnect said' end pieces from the line wire.

The' clip 23 is secured in position on the insulating block lO by means o' a bolt or pi'n- 25 which extends transversely through the insulating strip 10 for engagement with the reduced terminal? 19 of the adjacent arm `S), asbest shown in Fig. l() of the drawings,

sothat when the switch 22 is in closed posiand 6 may tion the current is free to. pass from the trolley 14 through the adjacent end piece to the switch and thence through the opposite end piece or contact and ott to the line.

' The lower longitudinal edges of the side plates S and 9, are preferably cut awayvto expose the lower longitudinal edge of the insulating block or strip l0, a portion of .each end piece, shown at the eXtreme ends of Fig. -1` being disposed flush Wirth thebase of the insulating strip l() to permit the ieady passage of the trolley wheel. It will thus be s eeii` that when the `switch is in closed position and the trolley wheel passes over the insulator said trolley wheelwill contact with the side platesA 9 and '10 so that should the motor stop when the trolley wheel is on the insulator said trolley wheel will be in-a position to start the motor.

By moving the switch laterally to inoperative position the end pieces or contacts 5 sulator may be cut out or disconnected from the remainder of the line should any disturbance occur on the latter.

Projecting upwardly from the upper longitudinal edge. of the insulating block or strip l0 is a bracket 26 having a socket 27 formed thereinfor the reception of a rod or hanger 28 by 'means of which the insulator may be readily suspended from an over-head support. I Secured to or formed integral with the end pieces 5 and 6V are cylindrical members 2.9 having openings 3() formed therein and extended transversely across the end piecesl will be separated from each other by the insulating strip 10 so as to cutout that section of the line wire carrying the insulator.

l The bridge wire 31 may be nsdalone or in connection with a switch, it being preferable to use the two together so that in case the switch should get out .of oider the bridge Wire 3l may be brought into service.

While there is shown a figure eight 'type of line wire it is obvious that said line wire may be circular in cross section or of any.

4other desired cross sectional contour in Which event the longitudinal and inclined be disconnected electrically so` v that the sect-ion of the line carryingthe ingrooves iny the end pieces may be made of a corresponding shape to lit said wire.

It will also be understood that any other for the switch shown in Fig'. 1 of the drawings without departing from the spirit'of the invention. Having thus described the invent-ion what is claimed is: y

1. A section insulator for electric trolley Isystems including spaced end pieces constituting contacts leach providedy with a re improved type of switch may be substitutedi duced extension over-lapping the reduced` A extension of the other end piece at approXiQ-'v apart, and bent. upwardly in the direction of hetop of the insulator to produce curved terminals there being longitudinal grooves formed in the end pieces for the reception of a line wire, an insulating strip interposed between the terminals, a clip secured tonne mately the center of the iiisulatoi, the ends` l` .of said' reduced extensions being spacedy side ot' the insulating strip above the 'lower longitudinal edge thereof'and connected with one of the upwardly curved terminals, a similar clip disposed on the same side of the insulator and also spaced from the lowerthe center of the insulator, an insulating strip' interposed betweenV the end, pieces', means carried by the end pieces for engagenient with a line wire, vthe lower longitudinal edges of. the endl pieces being spaced from the lower longitudinal edge of the insulating strip for a portion of their length, there being lips formed on the end pieces and adapted to bebent kupwardly `into engagement with the line wire, transverse sockets formed in the end pieces, a single point switch secured to the insulator on oneside thereof `and spaced from the lower longitudinal edge ot' the insulating strip for connecting ther over-lapped terminals of the end pieces, and an auxiliary switch disposed on the other side of the insulatorl and including a. bridge wire' adapted to detachably engage the sockets. i' f In testimony that we claim the foregoing as our own, we have hereto aixed our signaturesin the presence of two witnesses.`
