TRAMWAY-LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 276,075, dated April 17, 1883.

Application filed August 14, 1882.

To all whom it may concern:

Be it known that we, JOSEPH QUICK and JOSEPH QUICK, J r., subjects of the Queen of Great Britain, residing at 29 Great George Street, in the city of Westminster, England, civil engineers, have invented certain new and useful Improvements in Tramway-Locomotives and other Locomotives or Motive- Power Engines, (for which we have received Letters Patent in Great Britain, No. 5,575, dated December 20, 1881,) of which the following is a specification.

This invention has for its object improvements in tramway-locomotives and other locomotives or motive-power engines. On locomotive or portable engines'which require to carry a large quantity of gas fuel we provide a gas-holder in which gas can be stored under pressure, and we provide pumps on the locomotive or portable engine to be worked by the gas-engine for the purpose of forcing the gas into the gas-holder. From the pressure gasholder the gas is drawn off for use into a .bellows-like holder, and the valve between the two holders is opened by the collapse of the bellows-like holder and closed as it becomes inflated. The gas, in expanding, cools the passages through which it passes, and we cause the water by which the cylinders are cooled to pass through contiguous passages,thus restor ing heat lost during compression and expanding the gas to its ordinary working-pressure. The pistons of the engine we cause to give motion to a crank-shaft on which is a belt-pulley, and an endless band passes from this pulley to a loose pulley upon the main or driving axle. Upon the crank-shaft there is also a toothed wheel driving another like wheel on a countershaft, on which also there is a belt-pulley driving by a belt another pnlleyloose on the main axle. Between the pulleys on the main axle there is a double cone revolving with the axle and capable of sliding along it uponafeather. A neck formed in the cone is embraced by a fork which can be moved laterally by a screw and lover handle. The cone forms part of a friction-clutch and enters recesses in the loose pulleys, so that the pulley toward which the cone is moved becomes fast with the main axle, and movement is given to the wheels. Thus without interfering with the gas-engine, which (No model.) Patentedin England Decemberflt), 1881, No. 5,575.

runs continuously, the locomotive can be started or stopped or reversed.

In order that our said invention may be most fully understood and readily carried into effect, we will proceed to describe the drawin gs hereunto annexed.

Figure 1 is a side elevation of an eightwhceled tramway-locomotive. It is provided with a reservoir for carrying gas in a compressed state. Fig. 2 is an end elevation, and Fig. Sisa sectional plan, of the same; and Fig. 4, a cross-section on a larger scale. Figs. 5, 6, and 7 are views showing, on an enlarged scale, details of the low-pressure service-reservoir or regulator-bellows, of its connections with the high-pressure reservoir, the engine, and the valve by which to regulate the passage of gas from the high-pressure reservoir, and of the water-circulating devices for heating the gas on passingto the regulator-bellows. Of these views, Fig. 5 is a side elevation, with parts in section, showing the bellows collapsed and the regulator-valve opened; Fig. 6, an end view; and Fig. 7, a side view with parts in section, the bellows being opened and the valve closed.

A are the cylinders of the gas-engine; B, gas-supplypipe from regulating-bellows to engine; O, regulator-valve on pipe D, which leads from high-pressure gas-reservoir to regulator-bellows E; F, lever by which the regulator-bellows open or close the valve 0. The way in which this is effected is shown clearly at Figs. 5, 6, and 7. G is a gas-compressing pump by which the high-pressure gas-reservoir can be filled; H, supply-pipe to pump. It can be'coupled to any gas-supply pipe. I, delivery-pipe from pump to highn'essure reservoir; J, water-circulating pipe from watertank J tojacket surrounding cylinder A; K, water-circulating pipe from cylinder-jacket to jacket surrounding the pipe D and valve 0; L, water-circulating pipe from this jacket back to the water-tank J. It enters above the water-level in the tank. The water circulates by reason of its hmemieahea d iatheiae surrounding the cylinder A. M is the highv ser sas-r serrem By the above arrangement it will be seen that the gas'is first expanded from the highpressure reservoir M into the bellows E, and that heat is supplied to the gas as it expands.

If the pipe D and valve 0 were not kept heated, they would quickly become choked by the deposition of solid material from the gas. The regulating-valve O and pipe D are surrounded by the jacket C, which is warmed by the water which passes from the tank through the pipe J to the jacket surrounding the cylinder A, then along the pipe K to the jacket 0, and finally back to the tank through the pipe L. The pump G is for refilling the reservoirM with compressed gas, and is worked, as shown at Fig. 1, by a crank-pin on one of the driving-pulleys.

The crank-shaft N of the engine has upon it a belt-pulley, 0. It also, as shown at Figs.

1 and 4, drives in a contrary direction a second belt-pulley, O. The belt-pulley O by an endless belt drives a belt-pulley, P, which is loose upon the driving-axle Q; The belt-pulley O by an endless belt drives a belt-pulley, P. Either the pulley P or the pulley P can be locked fast to the axle by the frictionclutches R, and so the axle can be driven in either one or other direction, as required.

\Ve claiin- The combination, substantially as herein described, in a locomotive or other motive-power engine, of a high-pressure gas-reservoir, M, a low-pressure service-reservoir, E, a gas-engine, and water-circulating device for withdrawing heat from the cylinders and imparting it to the gas during expansion on passing out of the high-pressure reservoir, as set forth.
