ELECTRIC' RAILWAY.

SPECIFICATION forming part of Letters Patent No. 729,136, dated May 26, 1903.

Application led February 21, 1901- Serial No. 48,203. (No model.) i

To au whom, it may concern:

Be it known that I, ALBERT N. CONNETT, a citizen of the United States, residing at London, England, have invented certain new and useful Improvements in Electric Railways, of which the following is a specication.

This invention relates to electric railways of the conduit type, wherein the conduit is any suitable inclosure for protecting the electric conductors which supply the vehicle-motors and wherein a collector or plow which is suspended from the vehicle extends through a slot in the upper portion of the conduit and makes electrical contact with the conductors in the conduit.

The invention consists in means for moving a portion of the inclosure in order that when necessary the plow may be removed therefrom.

Of the drawings, Figure 1 is a lateral crosssection of a track and roadway to which my invention is applied, and Fig. 2 is a longitudinal section of the same.

The slot through which the collector extends into the conduit is necessarily Very narrow in order to prevent vehicle-wheels and other objects from entering it, and hence the shank of the plow must be very narrow in order to have free movement within the slot. Furthermore, it is necessary that contact-shoes or current-collecting mechanism on the lower portion of the plow within the conduit should be of considerable size in order that they may be successfully operative. Hence it will be evident that the plow cannot be raised or lowered through the slot and'that some means must be provided for temporarily removing a portion of the upper wall of the inclosure or, as is shown herein, of widen ing the slot.

Usually a plow is attached to the car in the car-barn, where the car is located over a large hole or open portion of the conduit; but there are several reasons why it is desirable or necessary to provide means out on the road for removing the plow from the conduit. The chief of these occurs in the combined urban and suburban roads where the conduit system is used within the city limits and the overhead line is resorted to in the suburbs, the cars being adapted to receive current the car.

from either system. In this case it becomes necessary to remove the plow from the conduit when the end of the conduitv system is reached and to lower the plow into the conduit on the return trip when the end of the overhead system is reached. In other cases it may -be desirable to remove a damaged plow from a car without first pushing the car to the barn. These dillcnlties have previonsly been recognized and have usually been overcome in practice by stationing a Workman at the end of the conduit, who when the car came to a stop would make thenecessary changes, which in some cases consisted in removing the plow from the car. In a railway equipped with my improvements, however, it is not necessary for any one to de scend into the conduit nor to work beneath The apparatus is such that the motorman or conductor can from the car-platform in a manner similar to which a roadswitch is operated or from a position in the roadway alongside the car actuate the mechanism which controls the conduit cover or covers to move the latter, so that the conduitplow may subsequently be removed from or lowered'into the conduit in any suitable manner-such, for instance, as that described in my application for patent, Serial No. 48,204, filed February2l, 1901.

In the drawings, C C represent the conduitcovers, which are moved to the position shown in dotted lines by the removable hand-lever Q in the hands ofthe car operator. The car runs on the rails R and carries the collector or plow L, which after the covers C have been moved tothe position shown in dotted lines may be raised, as also shown in dotted lines. fThe collector L in normal operation extends through the slot into the conduit J, and the contact-shoes N, carried by the co1- lector, engage with the positive and negative mains M. At the particular portion of the road at which the cross-section is taken the conduit J is enlarged to make room for the cover-lifting apparatus.

The supports K have depressed portions upon which the covers C closely rest in their closed positions, so that their upper portions are on a level with the road-bed.

Operating in bearings formed by the sup IOO port K and the piece K', attached thereto by bolts T are shafts S2 and S3, to which shafts are rigidly mounted the arms H and I, which are pivoted to the lower side of the cover O at that portion of the cover which does not rest upon the depressed portion of the support K. The arms or levers H and I are arranged parallel to each other, so that when the shaft S2 is given a movement of partial rotation the cover C will be raised away from the position in which it closes the conduit to another position which is parallel thereto.

Both covers C will be raised similarly and simultaneously, so that the slot, which normally is just sufficient to permit the passage ot' the shank of the plow, is widened to such extent that the plow can be freely raised or lowered without contact of any portion thereof with lthe covers. Furthermore, in case a heavy weight, such as a wagon or truck, should bear on the portion of a cover nearer to the slot than to that portion of the cover upon the stationary support K the l cover would not be depressed at such point, since it can move only parallel to its normal position, and thesupport K prevents movement of the other part ofthe cover. Also the strain on the part of the cover nearer the slot would be divided between the cover-support K and the arms or levers H and I. In no case if the parts are properly designed to have sufficient strength will the cover be depressed below its normal closing position.

The means by which the motormans lever Q imparts a movement of rotation to the shaft S2 will now be described. A main shaft S is suitablyjournaled in bearings in the bottom of the conduit As shown to the right in Fig. l, an arm A2 is rigidly mounted upon the shaft, and pivoted to this arm is a twopart linkAD, connected by an adjusting turnbuckle. A second arm B is pivoted to the upper end of the link D and rigidly secured at its farther end to a short shaft S', which is suitably journaled in the conduit. Secured to the shaft Sj is a socket-lever P, which extends toward an auxiliary slot Uin the roadway andis adapted to be engaged and reciprocated by the motormans implement Q. From this description it will be clear that the reciprocation of the implement Q will cause opposite movements of rotation to be imparted to the shaft S.

Rigidly secured to the shaft S are arms A and A', and links FI F are pivoted at their lower ends to these arms and are connected to the mechanism which operates the covers C C. A description of the mechanism for one of these covers will be sufficient to show the'operation of both. The link F', for eX- ample, is pivoted at its upper end to the lever Gr, which is rigidly mounted 'on the shaft or pivot-piece S2. Thus as the arm or lever H is also rigidly secured to the shaft S2 a bellcrank lever is formed, whereby when the implement Q partially rotates the shaft S the greales link F will pull down the arm G of the bellcrank leverand the arm II will carry the cover O to its upper position, which is parallel to its normal position, owing to the operation of the parallel lever I.

As shown in Fig. 2, the cover C is of considerable length, so that upon the shafts S2 and S3 are rigidly mounted a plurality of the above-described arms H and I, respectively. Also rigidly mounted upon the shaft S are arms A3, upon which are adjustably mounted weights W. These are for the purpose of giving inertia to the apparatus and maintaining it in stable equilibrium in any position. Thus in Fig. 2, for example, when the implement Q is moved to the right and the cover C is elevated the weight YV tends to maintain it in its open position.

As shown in Fig. l, a manhole with a cover O is provided, so that for purposes of repair access may be had to the interior of the conduit.
