To all whom, it may concern:

Chester, England, have invented new and useful Improvements in and Connected with the Propulsion of Street, Tramway, or other Railway Cars or Carriages, (for which I have;

obtained Letters Patent in Great Britain, No. 16,991, dated November-22,1888; in France, No. 199,833, dated July 26, 1889; in Belgium,

No. 87,168, dated July 27, 1889; in Germany; 110. 51,397, dated August 2-1, 1889; in Austria-Hungary, No. 32,401 and No. 62,47 6, dated February 17 1890; in Italy No. XLI, 383, dated July 30, 1889, and in Spain, No. 9,884,

, datedOctober 28, 1889,) of which the following is a specification.

This invention mainly relates to those systems of propelling street-tramcars and otherrailway-cars in'which compressed air is the motor fluid used and wherein such compressed air is laid on in pipes or conduits along the route in contiguity to the track and the air used by the motors is supplied to their reservoirs for feeding the motors at certain points along the said route.-

In applying compressed air to the above purpose it has heretofore among other modes been proposed to store up the compressed air in reservoirs or receivers carried on a separate locomotive-engine or on a special form of car at a sufficiently high pressure to last out the whole journey and back to the starting-place, 'or to lay a continuous air-main along the route provided with valves at he quent intervals, from which the reservoirs on the car are recharged, when necessary, by

stopping the car close to the nearest valve and making connection between the reservoirs and the main by means of a flexible pipe, the reservoirs so charged and thevalves being then closed and the pipe disconnected by an attendant on the car.

The mode or system of operating or-work ing tramway-cars and other railway cars or engines and the means and mechanisms or apparatus employed therein involving my invention consist asfollows: V

The mode of operating the tram or other cars or carriages consists in making connections between the air conduit or main and the air-reservoirs of the car or engine and charging or replenishing the reservoirs from the compressed -air conduit at points at certain intervals apart along the route, and then breaking such connections, the making or breaking connection being effected by the motion of the car itself. It will therefore be seen that instead of having to stop the car at the charging-valves and make and unmake connection with the air-main by hand we effect such connection or break it automaticallyi. 6., by the action or movement of the car. By these means the loss and inconvenience of frequent stoppages to make connection by hand in order to recharge the reservoirs is avoided, the car being thus enabled to run its course, picking up the compressed air for the replenishing of the receivers on its way as required. The means by which these operations are effected consist of automatic connecting and disconnecting devices, one of which is placed and works on the car and communicates with the reservoir and the other is placed on the air main or conduit, These two devices are so formed and operate that they form a substantiallyair-tightconnection when connected with each other: At certain intervals along this air-main we provide devices provided with valves, which for convenience of description we hereinafter call supply devices. Upon the car or in connection with the receivers, which are attached to or form a part thereof, we also provide devices provided with valves which we call receiving devices. These devices are so constructed that as the car continues running the receiving devices may be caused at the will of the driver to engage with the supply devices and so form a temporary connection between the air-main and the receiver, disengaging themselves immediately afterward as the car moves forward. One form of apparatus by which this connection is or, may be made consists of a hollow trunk or trunks, say, of cylindrical form, one or more of such trunks being arranged on or in connection with the compressed-air conduit, that or those on the car or engine and that or those arranged in connection with' the air-conduit being so constructed that it or they can slide upon or within the other and so disposed and arranged relatively to each other that while the car is in motion this sliding connection is first made and then broken or unmade. The trunks would be made or mounted in such a manner that they may adjust their altering relative positions or inclinations themselves during the action of making and breaking connection, said alteration of position being due to the movement of the car or engine. Both the trunks on the car or engine and those in connection with the air-conduit would also be provided with suitable valves operated automatically by the connecting-trunks or by the movement or the car or other suitable means, by which direct connection would be formed between the conduitand the reservoirs.

For street or road tramways it is necessary that the air-mains and supply devices should be so arranged as not to interfere with the other traffic on the roadway, and to effect this we therefore lay the air-mains below the surface of the street and covered on and by the road metalling, and we place the supply devices in boxes or chambers sunk below the level. of the street and closed by lids level with the street, and we cause these lids to be automatically opened by the car in passing to enable it to make connection with the supply device below. These lids are raised by means of a device such as a scoop carried on the car and suitably shaped, say, somewhat after the manner of a ploWsha-re,

- and so arranged that it can be lowered as the car approaches the box containing the supply device. The scoop enters and inserts itself under the lid, and raises it as the forward movement of the car drives the scoop farther under the lid until the box is fully opened. The lid is then retained in its open position during the passage of the car by a light bar or bars or other device carried along the car, and drops back into its shut position as soon as the car passes clear.

Instead of the car-trunk device being operated as just described, it may be a fixture below the car, in which case it would be arranged to run in agutter by the rails, and the supply device would be arranged horizontally on the air-main.

In cases where the nature of the route allows it the supply-valves, instead of being placed in boxes underneath the roadway, may be fixed in boxes at the side, or on elevated pillars with arms projecting far enough to reach the receiving-valves placed near the top of the ear.

Having thus specified generally the nature and effects of the invention, I will now proceed to describe it with reference to the accompanying drawings, which illustrate examples of apparatus according to the invention, and show means for carrying the invention into practical effect as an ordinary tram-" way, such means at the same time constituting examples of apparatus constructed and adapted to operate according to the invention.

Figure 1 is an elevation, and Fig. 2 a crosssection, showing a part of a tramway-car with details of the automatic connecting compressed-air-supply mechanisms. Figs. 3, 4, and 5 show in sectional elevation and plan further details of the automatic connecting mechanisms shown in Figs. 1 and 2; and Figs. 6, 6 6 and 6 are details of same to a larger scale.

With reference to the drawings, a. are the side-frame members of the car, consisting of tubes.

b are tubular vessels placed underneath the car and surrounding the axles c of the wheels (1, the axles c passing through internal tubes 1) and having clearance for the rise and fall of the car on its springs. These vessels b form annular reservoirs round the axles and are connected together by tubes b at right angles to them, and they may also be connected with tubes extending under the end platform of the car.

e is the engine for driving the car. It is of the revolving type, such as Riggss or Wilsons revolving engine. The engine c works a shaft 6', carried across the car and geared to the two axles c by chain and chain-wheels f. The engine is a reversing one, regulatinglevers being connected to levers fixed on the platforms of the car at both ends, so that the engine can be controlled from either end thereof.

Referring to Figs. 1, 2, 3, and 6, A is a hollow trunk of duplex form and adapted to move about its axis and engage automatically with the device M, hereinafter described. B is a bearing supported by the bracket B to the body of the car, and B is a bracketin which, respectively, the hollow trunnion A and the solid journal A of the receiving device A are placed and work. B is an an nular passage in the bearing B, communicating with the interior of the hollow trunnion A by ports A in said trunnion, and C is the pipe, which communicates between the passages 13 and the air-reservoir at any suitable point. M is the supply device with which the trunks A engage automatically, and consists, mainly, of four hollow pistons mounted on the l1ollow body N, which is adapted to revolve upon the hollow trunnion N. O is a box, the upper surface of which lies even with the surface of the street. P is the compressed-air main. P is the pipe communicating between the main P and the trunnion N, and P is a stop-valve on said pipe P. D isa scoop device adapted to engage with and open the door or lid 0 of the box 0, and is hinged to the plate D, which is supported to the body of the car by brackets E, said scoop being operated by the lever F and rod F from the carplatform. A scoop D, plate D, bracket E, and lever and rod F and F are provided in double-ended cars in duplicate-that is,

ITO

on each half of the caras in Fig. 1. The plates D'- support brackets E, which in turn support the bracket B for receiving the journal of the receiving device A. The lid 0 is hinged at 0 and is provided with channels 0 formed by projecting bars 0 which are adapted to receive the rollers a on the trunk A-and guide the same. Q is a grooved rail provided for av certain distance on each side ofthe box 0, in which the toe of the scoop D slides as it approaches the box 0, the door of which is cut awayatits leading edges at 0, Figs. 4 and 5, to receive the toeof the scoop.

The detailed construction of the receiving and supply devices A and M are shown in Figs. 6, 6 6 and 6 and Fig. 6 shows these devices engaged with each other and in the position cut 06.

in which communication is formed between the air-main P and the car-reservoirs. In the position shown in Fig. 3 no air can flow from the main up the arm Mthat is, it is cut off. This cutting off and supply is effected by the movement of thedevice by means of the valve m, in which a port is provided in the top, (see Figs 6 and 6 so that as soon as the openings of the arms M come opposite the valve openings or port by the rotation of the device upon the trunnion N, air is admitted.

to said arms and upon at'urther movement is The valve m is fixed by the pin m, and the joint between the body N and the trunnion N is kept air-tight by the packing m The trunnion A of the deviceA is made air-tight with the socket or hearing B by pack ings j, and'air is prevented from escaping by way of the device from the pipe 0 and reservoir by the non-return valves A The joint between the arms and the trunks A is effected by a cup-leather j. 1

In the operation of charging the reservoirs position the lid 0 is held by. the bar D until all the operations presently described are completed, when it falls down of itself and closes the box. In the open position of the lid 0' the rollers a of the trunks A will lie in line with the entrance of the channel 0 of the lid and will enter same; and as the car moves still farther forward the trunk A is, owing to the channel 0 and roller 0/, caused to move about its axis and to assume the position'shown in Fig. 3, and eventually to engage with one of the arms M, the axis of which lies in line with the direction of the.

channel 0 when the lid is up. The receiving and supply devices A hl having become engagedwith each other, the-continued movement of the car forward will cause the device M also to move about its axis, and in so doing admitting air to and allowing it to flow from the main P up one of the arms M, and so on past the valve A of the trunk A into the carreservoir. If a number of trunks Asay threebe provided on a car or the supply devices M be placed sufficiently frequently along the route. or the size of the air-passages of these devices be made large enough, or any combination of these things be provided, the car may be charged with compressed air without stopping at all; but if the desired volume and pressure of air cannot fiowquickly enough from any cause while the car is in motion, then it must be stopped, and at a point when the devices A and M are in about the position shown in Fig. 6.

In the action of breaking the connection of the devices A and M the roller a, which entered the leading channel 0 when making connection, now passes upward through the channel at the opposite end of the lid 0, and in so doing causes the arms M to be left in the correct position for another engagementnamely, that given in Fig. 3. This roller and guide also brings the device A into'the position shown in Fig. 1, in which position they are locked bythe spring-retained catches Z which fit in the mouth of the hollows of the trunks A, and so arranged that theyareeasily pressed back when the rollers a enter or leave the guides 0 After the device A and the scoop D are clearof the door 0' the door 0 falls down and closes the box.
