JOSEPH I-IAGGAS, OF UXBRIDGE, ASSIGNOR OF ONE-HALF HIS RIGHT TO VILLIAU GOODESHAM, OF TORONTO, ONTARIO, CANADA.

IMPROVEMENT IN FEEDING LOGOMOTIVE-TENDERS.

Spccilication forming part of Letters Patent No. 206,560, dated July 30, 1878 application tiled May 25, 1378.

To all whom it may concern:

Be it known that I, JOSEPH HAGGAs, of the village of Uxbridge, in the county of Ontario, in the Province of Ontario, Canada, mechanical engineer, have invented a certain new and useful Apparatus for Supplying Locomotive-Tenders with lVater, which apparatus is fully set forth in the following specification and accompanying drawing.

The object of the invention is to provide an apparatus for raising water which will enable railway companies to dispense with the cX- pensive elevated tanks and pulnping-gear now used and necessary for supplying the locomotive-tenders with water; and it consists in fixing to some convenient part of the locomotive an injector connected to the tender by a suitable pipe, and furnished with other apparatus so arranged that a small quantity of steam taken from the locomotive-boiler will raise water from below the level of the track and force it into the tender.

Figure l exhibits arrangement of my elevator connected to a pipe leading to a groundtank 5 Fig. 2, sectional detail of my spherical injector, Fig. 3, sectional detail of a groundtank and pipe.

In all injectors with which I am familiar the amount of steam required to raise a given quantity of water is so excessive as to render them impracticable for lifting a large body of water in a limited space of time. As my injector is designed for a service in which time is a main object and economy in steam neces sary, all the details in iis construction have been directed toward accomplishing the desired ends.

The injector itself is formed by a spherically-shaped vessel, A, having an inlct`port, b, as' nearly opposite to the outlet-port l as the required position of the steani pipe a permits, the said steam-pipe being relatively of small diameter and projecting within the vessel A beyond the entrance of the port b. This arrangement of the ports b and d and steanrpipe a permits the free passage of the water, and does not, as in other injectors, present any angle or obstruction to check the velocity of the water passing through. Con` sequently, as the full effect of the velocity is retained the amount of steam necessary is con` siderably lessened, the desired effect being' further assisted by the steam-pipe a project-ing within the vessel A beyond the port b. The requisite vacuum is thus better maintained.

The pipe B is attached to the port el, and connects the injector to the tank C. The jet a is supplied with steam from the boiler D by the pipe E, which is furnished with a cock, F, placed in any suitable position convenient for the driver in charge of the locomotive.

In Fig. l I show the suction-pipe G coupled to the inlet-port d, and an elbowpipe,l, which leads into a tank below the level of the track I. This latter pipe is optional, as the suctionpipe G could be len gthened and made to serve the whole purpose. I prefer, however, using an elbow-pipe, H, as a permanent iixture to ground tanks or wells when used.

The joint g between the suction-pipe G and elbow-pipe H is a tapered male and female, as shown in Fig. 3, and is not bolted or in any other way fastened together except by the atmospheric pressure. Although it will, of course, be advisable to provide frost-prooi' tanks at convenient points ofthe road, one ot' the many advantages of my invention is that in case of necessity' the locomotive can draw water for the tender from an adjacent river or well, the distance'bein g regulated by the length of the suction-hose supplied and the law of pneumatics which governs the height to which water can be raiscd by atmospheric pressure. It should be noted that the injector A and pipes B and E are permanently connected to the locomotive, while the suction-pipe Gr is detachable. This latter pipe, when not in use, may be carried under the running-board J, as suggested by dotted lines, or in any other place upon the locomotive which the driver may consider most convenient.

The foregoing description, taken in connection with the accompanying drawing, is sufficient to enable any engineer to understand the application and operation of my invention. I will therefore merely add that the steam, rushing through the jet a, produces a vacuum in the injector A, causing the water to rush through the pipe B into the tank C, the water thus supplied being of course raised in temperature by the steam which accompanies it.

It is not necessary to specify the dimensions or the material used, as the knowledge of the purpose for which the invention is used will enable any competent engineer to determine them.

What I claim as my invention is- 1. A spherically-shaped vessel, A, having inlet and outlet ports and a steam-pipe, all arranged as described, and provided With suitable suetion and discharge pipes, combined with alocomotive-boiler7 for the purpose of raising Water to the locomotive-tank, substantially as set forth.

2. An injector having a suction-pipe provided with the joint g, constructed as de.- soribed, and a tender-supply pipe and oonnections7 combined with and arranged with relation to a locomotive-boiler, substantially as and for the purpose specified.

Dated at Toronto this 1st day of May, A. D. 1878.
