CHARLIE E. HUBBS, OF STREATOR, ILLINOIS.
UNDERGROUND TROLLEY SYSTEM.
SPECIFICATION forming part of Letters Patent N0. 549,920, dated November 19, 1895. Application filed May 23, 1895. Serial No. 550,403. (No model.)
T0 at whom it may concern:
Be it known that I, CHARLIE E. HUBBs,a citizen of the United States, residing at Streator, in the county of La Salle and State of Illinois, have invented a new and useful Underground Trolley System, of which the following is a specification.
My invention relates to electric street-railways, and particularly to a trolley system adapted to be arranged below grade or below the plane of the track-rails.
The objects in View are to provide a simple and efficient construction and arrangement of parts whereby a conductor of large cross-sectional area may be employed, to provide simple and efficient means for insulating the con ductor to prevent leakage, to provide means for supporting the conductor out of the path of rain and snow admitted through the slot, and, furthermore, to provide efficient means for operating the trolley-pole.
Further objects and advantages of this invention will appear in the following description,and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings,Figure 1 is a transverse section of a road-bed constructed in accordance with my invention. Fig. 2 is a detail view in perspective of one of the castings which combine to form the conduit. Fig. 3 is a detail View of the joint between the ends of two connected sections of the conductor. Fig. 4 is a side View of the means for operating the trolley pole or arm, a portion of the road-bed being shown in section to indicate the manner of mounting the trolley-wheel. Fig. 5 is a detail view of the means for guiding the trolley arm.
Similar numerals of reference indicate corresponding parts in all the figures of the drawlngs.
Arranged upon horizontal transverse ties 1 is a cement bed 2, the center of which is depressed to form a drain-basin3, which communicates by means of suitable piping 4 with a sewer (not shown) whereby water entering the conduit is carried off and prevented from accumulating therein. Resting upon the cement bed 2 are transversely-opposite castings 5 and 6, provided at their outer ends with ears '7, which are bolted to the webs 8 of. the rails 9, said rails having their bases resting upon the upper surface of the cement bed. These 7 castings comprise horizontal bases 10,webs 11, and concave fianges'12, the flanges 12 of the opposite castings having their concave faces arranged to connect with or merge into the concave surface of the basin 3. The lateral ears 13, which are flush with the upper edges of the webs of the castings, support roadplates 14 and 15, which are bolted thereto, the plates 14, which are arranged upon one side of the slot 16, being provided at intervals with hinged sections 17, whereby access to the interior of the conduit may be had for the purpose of repairing the conductor or cleaning the conduit. The casting 5 comprises a main or body portion or section and a removable or auxiliary section 18, the contiguous ends of said main'and auxiliary sections being provided with cars 19, connected together by bolts 20, and in the contiguous edges of the main and auxiliary sections is formed a seat 21 for the conductor 22, said conductor corresponding approximately in cross section with a T rail and having a flanged base 23, a web 24, and a tread or head 25,
the latter being preferably of copper. Interposed between the base of this conductor, which is arranged in the upwardly-flared or dovetailed seat 21, and the seat is an insulator 26, preferably formed of glass. The slot 16, being formed between the outer extremity of the auxiliary section 18 and the contiguous end of the casting 6, is removed laterally'from the plane of the conductor a distance .sufiicient to prevent water entering the slot from coming in contact with the conductor, and also toprevent objects inserted through the slot from the exterior from touching the same. The lower or free edges of the insulator 26 are flared outwardly toward their lower extremities, as shown at 27, to act as guards, and the auxiliary section 18 of the casting 5 is provided between its inner extremity and the seat 21 with a depending drippoint 28 to prevent water running down the face of the casting from passing inward beyond said point.
The trolley-arm 29 extends vertically downward into the conduit and is provided with a horizontal extension 30, terminating in upstanding ears 31, in which are mounted the trunnions of the trolley-wheel 32. Said trun- ICO nions are mounted in bearin g-blocks 33,which are fitted to slide in vertical slots 34: in the ears, tension-springs 35 bein employed to cause the wheel to follow any irregularities of the conductors without jarring or straining the trolley-arm. The conductor is preferably formed in sections provided with halved or rabbeted extremities, as shown at 36, said ends being preferably soldered and riveted together.
The trolley-arm is provided with a rack 37 and is fitted in a guide 38, having a removable face-plate 39, said face-plate being held in place by means of keyhole slots 40 formed therein engaging headed studs 41 at the sides of the guide. Engaging said rack is a pinion 42, to which are secured sprocket-wheels i3, engaged by endless chains ll. By means of these chains motion may be communicated in either direction to the trolley-arm by means of the operating spindles 15.
From the above description it will be seen that aheavy conductor may be employed, and that when arranged in the seats provided for its reception in the conduit it is protected from contact with foreign substances introduced through the slot. It will be seen, furthermore, that any desired section of the conductor may be removed and replaced when necessary, and that the mounting of the 0011- duetor in the seats is facilitated by the removable section of the casting, between which and the main section of the casting the seat is formed.
The hinged portion 17 of the road-plate rests upon the castings, and the conductor is supported solely by the castings. The hinged sections 17 are preferably arranged eontiguous to every other or alternate castings, and in practice the insulating material maybe arranged upon the alternate or intermediate castings.
The feed-wire 40 is arranged in the aligned openings of the castings 11 at one side of the conduit, and the return-wire 47 is arranged in the aligned openings of the other casting, and the return-wire should be tapped to the rail at intervals corresponding with those at which the feed-wire is tapped to the conductor or trolley-wire. Said feed and return-wires are insulated throughout and are supported by pins 48, having suitable insulating-seats 49, through which the wires extend.
In practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
Having described my invention, what I claim is- 1. A conduit for underground trolley systems, having transverse ties, a cement bed supported by the ties and having a centrally depressed drain-basin connected with a drainpipe, sets of opposite castings cut away at their inner ends above said basin and terminating contiguous to each other to form a slot,
