To (all 007mm it may concern:

lie it known that l, HARRY E'riimnnsn, a citizen ot the lvnited States, residing at Zellenoplc, in the county ot Butler and State oli Pennsylvania, have invented certain new and useful lnnliroveinents in hilotor Leads Connections for StreeteC/ars; and l do declarc the tolltjnving to be a t'ull, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to nmlY and use the same, retcreuce being had to the accompanying drawingsl` and to the letters and vfigures ot roten ence marl-ted thereonr` which torni a part ot this specification.

v invention has for its objects the provision ot' a leads connection between the conduits and motors carried by electrically operated street cars, whereby flexibility of said leads is attained between their fixed points, permitting the trucks carrying the motors to follow any curvature and thus prevent crystallization and consequent breaking oit the leads heretofore occasioned therein when disposed in the ordinary manner.

liurther objects oit my invention are to dispose the leads in a position over the top ot the motors where they are less apt to sustain iuiuryr` and where access thereto may be readily had when necessary.

Again, the invention has ttor a further object the sogar-ating and holding ot the leads connections in operative position as they issue from the conduits, the means employed to etl'ectmy objects being fully shown in the accompanying drawings and set forth in this specification.

In said drawings. Figure I, is a side elevation ot a portion ot a double car truck, in longitudinal section, together' with the conduits carried by the car and slimviug the application or my invention thereto. F ll, a plan view ot the same. Fig. lll, is an enlarged side elevation ot one ot the leads connections, and Fig, lV, is a transverse sectional view through the conduit outlet member, in all ot which views similar detail. parts are designated by numerals of like character.

Upon it'urther reference to 'the drawings the numeral 1 designates the line ot the car body, i2 the leads conduits secured to said body and the motors carried upon the wheel axles it ot the truck and the transverse truck traine portions 5, the pivotal point of the truck to the car body being designated by the character X, all of which are well known in the art.

The invention comprises a T connection. G carried by each conduit 2, each T having rigidly secured thereto a horizontally disposed outlet member formed oit the two parts 7 and 8 connected to one another and provided with registering parallel grooves be tween which are clamped insulating tubes 9, the conductor leads 1G, 11, 1Q and 13 within the conduits being passed down into the said outlet member and extending part way into the said insulating tubes the ends ot each carrying a connecting terminal 1l. i

The insulated connecting leads 10, 11, 1Q and 13 located above the motors are each connected to one ot the conductor terminals within the insulating tubes of the outlet member by means of screws passed through duplicate terminals 14: carried thereby, said leads connections being each formed into a horizontally disposed loop projecting` from and in the direction oit the said outlet meinber tor some distance and then returning in the opposite direction and passing into the motor, each or the leads loops being in parallel relation with one another and in the same horizontal plane and secured in position upon the motor by cleats 15.

Upon the ends o1 the insulating tubes, where they issue from 'the conduit outlet members, and the` leads connections, is secured a secondary clamping member 1G divided longitudinally into two parts secured to one another by screws and said leads being protected throughout by a covering termed o spirally wound brass wire 17.

By means of the described leads connections tor the motor it will be readily apparent that as the truck carrying the motor adjusts itself .in rounding any curvature ot the track the said leads connections will like wise adjust themselves in accordance to the truck movement the strain thereon being distributed throughout the length ot the loops.

Then it is desired to remove the motor and attending truck for repairs, etc., the lower section S of' the conduit outlet member is detached and the secondary clamping member 16 is slightly loosened, atter which the insulating tubes 9 and secondary clamping member are slipped along upon the leads loops, sutlicient to expose the connecting terminals 14 and 14, after which the said terminals may readily be disconnected and the motor and truck removed, and as the secondary clamping member and insulating tubes remain intact upon the leads loops they may be easily replaced in position, the terminals connected and the outlet member section replaced ai'ter the motor and truck have been restored in position.

Having thus fully shown and described my intention, what I claim as new and desire to secure by Letters Patent, is:

l. rlhe combination With a motor carried by a car truck and a conduit carried by the car body, of a plurality ot conductors extending through and from said conduit to the motor, said conductors, between the motor and conduit, beingeach formed in an approximate horizontally projected loop disposed edgewise in approximate parallel relation With one another. and a member carried by the conduit to distribute the conductors and rigidly secure the same in spaced relation thereat.

Q. The combination With a motor carried by the car truck and a conduit carried by the car body, of a plurality ot' conductors ex t tendine,l through and from said conduit to the motor, said conductors, between the motor and conduit, being each formed in an l approximate horizontally projected loop disposed edgewise in an approximate parallel relation with one another, and a mear ber carried by the conduit to distributie the conductors and rigidly secure the same in approximate horizontally projected loop il.

disposed edgewise in approximate parallel relation with one another, and a member carried by the conduit to distribute the conductors and rigidly secure the same in spaced relation thereat, the loop portion ot each conductor being detachabljtv connected to the main portion and all insulatedly connected to one another where they issue from said member.

In testimon-y whereof, I afiix my signa- 5' ture, in presence of two Witnesses.
