PUMPING DEVICE.

vented a certain new and useful Improvement in Pumping Devices, of which the following is a specification.

This invention relates to pumping devices of the ejector type and, more particularly, to an improvement in. the special type of ejector pumping apparatus patented by me Dec. 13, 1898, No. 615,992. a

The object of the invention herein is to simplify the said former patented device, to reduce its cost of manufacture and repair and to render it more eflicient for the re quired service that combines the lifting of water and other fluids from a vertical as well as horizontal intake, as well as to further force or eject the water beyond the mere lifting stage but-not against pressure such as is present in connection with an injector device.

The constructive features of the present take and, also, with an auxiliary cold water service attachment that adapts it to the pumping of water or other fluids of ahigher temperature than that possible with my previously patented device, and Fig. 2 is a central vertical section, partly in elevation, showing my device with a vertical intake, but with the controlling valve of the auxiliary hydrant attachment omitted.

1 indicates the body portion or main shell containing the vacuum-chamber 2 and extending upwardly into an outlet or discharge end 3, the latter having a slightly contracted throat 4, all as best seen in Fig. 2.

5 indicates a steam inlet-nozzle having a screw-threaded portion 6 that engages a .threaded opening 7 in the body portion 1 and centrally alining with the outlet 3. An angular-formation 8 is provided on the outer portion of the steam-nozzle for use in turning it to and from operating position and, also, in properly adjusting said nozzle for the best suited delivery of the steam-jet in the vacuum chamber 2. The extreme outer end of the nozzle is threaded, as'shown at Specification of Letters Patent.

Patented Nov. 2, rare.

Application filed April 16, 1913. Serial No. 761,570.

for the desired engagement of the steam supply-pipe that is not shown herein. The nozzle has a tapered inner end 10 and an inwardly-beveled mouth or inlet-opening 11, and its internal bore has a wide passage 12 that terminates in a narrow passage 13, a shoulder 14 intervening, whereby the volume of steam is somewhat compressed in its passage through the nozzle.

A vertical Y-branch 15 extends laterally and downwardly. from the body portion or shell 1 and is intended for the upward passage of water or other fluid that is to be lifted from below. This Y-branch has an internal screw-thread 16 in its lower end or mouth for the engagement of an externally threaded coupling-pipe 17, to which latter an elbow 18 is attached in Fig. 1, and a vertical pipe 19 in Fig. 2, said elbow 18 having a horizontal pipe 20 engaged with its outer end for a horizontal passage of the water from below, and the pipe 19, of Fig. 2, forming a vertical intake from below. It will be observed that the ejector portion of my device herein remains unchanged for both the horizontal and vertical intakes, which'forms an important feature of the invention herein and is of great advantage to users of this class of pumping devices.

In the operation of the device it will be observed that the upward passage of the water from the intake into the curved branch 21 is not impeded by any material obstruction and is smoothly guided into the vacuum-chamber that is occupied by the tapered point 10 of the steam-nozzle, the jet of steam that projects into the throat of the discharge-orifice 3 efiectually providing the necessary vacuum into and beyond which the water rushes for its upward lift, either for. an ordinary flow or discharge above, or for an extended pressure or force beyond, as desired. The extended pressure or force of the water beyond the ordinary lifting and flowing stage is accomplished by means of an increased pressure of steam beyond .that which is necessary to simply lift the fluid. Besides, the discharge-passage is not a small one. although somewhat smaller than that of the curved passage 21,,the latter leading from the intake-coupling 17 and, also, somewhat larger than the boi'e of said intake- .coupling 17.

While the device is capable of pumping cold and hot fluids alike, its capacity to pump fluids of a very high temperature is augmented by means of the auxiliary hydrant pressure or service device that is attached to the inlet 22 made in the Y-branch of the shell and is composed of a short nating from the screw-coupling 17 of the intake is atonce intermingled with the cold water and so reduced in temperature as to be ready for immediate advance into the vacuum-chamber 2 and thence projected beyond into the discharge-orifice without choking or clogging the vacuum-chamber. This cold water auxiliary or adjunct is an important feature of the invention herein be cause it adds materially to the use and capacity of the former device in which the pumping of fluids of as high temperatures could'not be reached. Water at as high a temperature as 170 degrees can thus be cooled right at the vacuum-chamber sufficient to properly pass into the vacuum-chamber and thence into the discharge-orifice, without the entrance of the latter being choked or clogged by any accumulation therein. Hose can be attached to the screw-threaded exitend of the discharge-orifice for use in throwing water for fire, cleaning, flushing, or other similar service.

4 In using the device in connection with a horizontal intake it is obvious that it will not require the same amount of lifting power or pressure that it will in connection with the use of a vertical intake and, in such event', the use of a horizontal intake is adapted to water as well-as steam power or pressure in the power nozzle for'effecting the required vacuum for both lifting and forcing any water or fluids that enter said horizontal intake. This is an important fea- 'ture in connection with the adaptability of the invention herein, to either a horizontal or vertical intake, but necessitating the use of the steam pressure in connection with the vertical intake unless an abnormalpressure of water can nozzle.

I claim v 1. An ejector device comprising a shell having an, outlet or discharge orifice, a steam-nozzle mounted in said shell in axial lalinement with said discharge-orifice, a

downwardly-curved Y-branch leading from said shell at a point coincident with the extreme exit end of said steam-nozzle, and an intake leading from either a horizontal or a vertical source of fluid-supply into a curved passageway in said Y-branch that discharges said fluid-supply into the vacuum-chamber be supplied to the power at the point of said exit-end of the steamturned and curved Y-branch leading from said shell at a point axially coincident with the point or extreme exit end of said steamnozzle, anintake coupling in the inlet end or mouth of said Y-branch adapted to receive the connecting end of either a vertical or a horizontal intake, and a valve controlled cold fluid supply-pipe leading under hydrant pressure into said Y-branch at a point thaltl precedes that of the vacuum in the she THOMAS E.
