To all whom '52? mug concern Be it known that l, Bonner V. Mouse, e
' citizenof the United States, residing et lithof which the following is u specification.
This invention relates to sir-compressing epperutus of. the type in which n pump is employed for circuleting or other l quid, and air is drawn circulated with the liquid. The air may then he allowed to separate from the water vor other liquid, end
be stored in e tank, or in csse'oi' vecuuin pump, may be sllowedto escape with the dischergerreely to the atmosphere.
:Cne object of my invention is to increase the-efdciency of pumping apparatus of this.
type, both for compression and vacuum pur poses by introducing the sir into the liquid ntthe. suction or intake ot the pump and passing both the water and the err through said pump. The water ebsorhs the heat of compression thus giving practiced isothermsl compression with its consequent advenzteges.
v.rluiother feature of my improvement re- :lutes to gtheseving of power by utilizing the discharge or" the water or other liquid from the separator or storage tank for assisting in driving the circulating pump.
Another object of myiinvention is to provide unimproved combined epperstus having the double 'ilunction or draining mines or other places of water, and at the some time furnish compressed air for o crating :mining tools, such es pneumatic orills, or for other-purposes.

In the practice of my invention, any suit ,able form of liquid circulating puncp may be employed, suchesthe rotary or centrifuhs-igalpump, 5, as shown in Fig. 1, having a suction p1pe, '6, communicating with e resercvmr, 7, mother source of watersupply, the

pump being driven from any suitable source of ower such as the motor, 8.
ccording to one of the features of my improvement, the air is introduced or drawn in to the suction pipe of the pump, or at any point where the pressure is less than atmospheric, and any desired amount of air may he admitted by any suitable means, one such device being shownin Fig. 3, in which the suction pipe is contracted at the pump intake and the air inlet nozzle, 9, leads into the central portion of said intake; The air intake pipe, 18, may be provided with u throttle valve, 10, and an automatic check vslve, 11, which does not open until the suction is suficient to have filledthe pump with water A check valve, 12,, may be located at the foot of the water uptake or suction pipe, e. As the water is drawn into the pump through the restricted suction opening eround the air inlet nozzle, the increased velocity of the water serves to draw in the air in the form of u continuous stream or" bubbles, which ere pocketed by the water end with it forced through the pump where the air is compressed and discharged with the water through the outlet pipe, 13, into n separating and storage tank, 14. Any suitable. means may be employed for separating the compressed air from the Water discharged from the pump.
According to the modification shown in Fig. 4, theeir inlet pipe, 18, may communicute with e chamber, 15, surrounding the water suction pipefi, and having it series of holes, 16, through which the air is admitted in the form of bubbles into the Water as the some is. drawn into and forced through the As the mixture of com ressed air sud water is discharged throng pipe, 13, into tank, 14, the bubbles rise and the air is separated from the water and stored under pressure in the top of the tank from whence it may be drewnofi' for use by a valve in eny manner desired.
The water in the tank is normally maintained at o constant level by any suitable menus and the return water which discharges through pi e 19, under the pressure of the tank is pre erably utilized upon an as a multi-stage pump, as shown in Fig. 5,
' V In this case, the pump an may be used where higher pressures are desired, as will be readily understood. When the pump stops, the valve, 12, closes and retains the intake pipe, 6, full of water. Upon starting the pump, the air inlet pipe may be closed by means of valve, 10, which may then beslightly opened to permit the admission of the desired amount of air without interrupting the water suction of the pump. The check valve, 11, in the air inlet pipe may also be so loaded as to remain closed until the suction is sufiicient to have filled the pump and intake pipe with water. It also serves to throttle the admission of air to some extent and closes automatically whenever the suction is broken or the pump stops;
As shown in Fig. 2, the improvement is applied as a vacuum pump for exhausting air from a chamber communicating the air pipe, 18, and the discharge pipe, 13, from the pump may lead directly to the atmosphere, or return to the reservoir and the air allowed to escape, as indicated. a In this case, it will be apparent that the height of the water column in the intake pipe, 6, indicates the measure of the degree of vacuum maintained in the air intake pipe and chamr. g As illustrated in Fig. '5, my improvementis ap lied in connection with a multi-stage centrifugal or turbine pump, 5, used for draining mines, or other dplaces, of water.
motor are refs erably located near the bottom of the s aft, while the separating tank, 14, may be situated at any convenient position, and the discharge; ipe, 20, from't e tank, leads to the top of-t e shaft for carryin ofi the drainage water. Air is introduce by inlet pipe,
18, into the suction intake, 6, of the pump, 7
and is forced throu h the same withthe water which is then elivered through pipe, 13, into the separating tank, -14,-where the com ressed air may be stored ready'for use.
' ere, as is thecase in many mines, great quantities of water must bepumped out contlnuously, there will be suflicientwater available,'and the return ipe, 19, andim ulse -wheel, 17 may then 'dispensed'wit if desired; Ibe ap aratus then operates as an efiicient s stem or pumping out drainage water an at the same time compressin air for use in connection with pneumatic rills and other mining tools, as indicated'at 21. The height of the column of water in the drainage dischar e 20 above the separating tank determines t e air pressure in the tank,
and the latter may be laced at the pro r elevation to give the esired result m t is res ect.
f there is not sufiicient draina water to 3 handle the desired quantity of air for comression, some of the water may be returned with said intake, a source of power for riving,
