To-all whom it may 0mm;

Be it known that I, WrLm G. WILSON, a sub'ect of the King of Great -Britain,-residin in t e city and county of Denver and State o Colorado, have invented certain new and useful Im rovements in Air-Com ressors; and. I do declare the following to lye a full, .clear and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains same, reference being had to the accompanyrence marked thereon,which form a part of this specification. y I My invention relates to improvements in air compressors and specifically to a device in which water is used as a vehicle to carry the air into the receiver and through the same.

In carrying out the invention I employ a centrifu al I pheric air is introduced to t e body of water and carried with the latter into the receiver. The body of water or other liquid in the receiver is such that there is always an air s ace above in which the air is compressed. rovision is made, after a given or predeter mined body of water has accumulated in the receiver, for drawing off the water as fast as it enters, thus maintaining a uniform quantity of water in the receiving tank. While the water is drawn off the air is tra ped and the compression of the air is broug t about by thecontinual introduction of air into the space above the liquid. 1 Having briefly outlined my im roved construction'I will proceed to descri e the same in detail reference bein made to the accom panyingdrawing in w 'ch is illustrated an embodiment thereof. In this drawing, Figure 1 is a-section taken through an a paratus illustrating my imrovement. ig. 2 is a section taken on the iine 22 of Fig. 1 Fig. 3 is a perspective view in detail of one of the nozzles for introducing the air to the chamber of the ump, whereby it is acted on by the stream 0 water. Fi 4 is a view partly in'section showinga mod' ed form of construction.

The same reference characters indicate the same arts in all the views.

Re erring first to Figs. 1, 2 and 3, let the numeral 5 designate a centrifugal -pum which so far as its general construction is concerned may be of any approved form. In

to make and use the 1 drawings, and to the letters and figures of pump so arranged that atmoslarged as sh thisppmp, 6 is the casing; 7 the induction conduit; 8 the eduction conduit; 9 a controlling valve interposed between the educt1on conduit and the receiver 10; 12a return condultleading from the bottom of the rece ver to the supply'tank 13, :in Whichconduit ls-interposeda valve 14;-15 theshaft of the1mpeller16,the said shaft bein journaled in a suitable support 17 and rovicied with an operating pulley 18. The back wall of-the casing is provided with an opening 19 around the Impeller shaft, said openingbeing surrounded an exteriorly protru ller on the side of the pump corresponding with the opening 19, is provided with open ended nozzles 21, one extremity of each of which projects into the opemn 19, while. the opposite extremity is directe outwardly toward the periphery of the casing, to facilitate the introduction of air during the action of the pump. The outer extremities of these nozzles are enown at 22, to further facilitate the introduction of air, the said nozzles being ppoperly directed to produce this result.

ithin the housing 20 is preferably located a fan 23 whose function is to draw atmospheric air 'thereinto and pass it thence to the mduction nozzles.

When the device is in operation the impeller shaft being rapidly rotated, imparts a correspondin movement to the impeller 19 and the nozz cs 21, whereby liquid as water is drawn from the supply tank 13 up through the conduit 7, into the pump chamber, where it is acted on by the revol impeller. As the water is thrown outwar y into the perifphery of the casing due to the rotary actlon o the impeller, air is drawn into the water and forced upwardl therewith into the receiving tank 10. en the o eration is commenced, the valve 14 shoul be closed until a bod of water 24 accumulates in the receiver. he valve 14 is then opened sufliciently to allow only as much water to escape through the pipe 12 as enters the receiver through the ipe 8. By virtue of this arrangement, t e water is continually drawn ofi, thus leaving a uniform air space within the receiver, into which the air is forced durn the continued operation of the apparatus;

11 the form of construction shown'inFig. 4, the receiving tank will be designated 10, the same as in Fig.1 In t casea cen- Patented Oct. "13, 100s.

trifugal ump 25 is employed and water is delivered to the bottom of the tank 10 from a conduit 26 leading from the pump, the water being delivered to a nozzle 27 projecting into an inverted funnel-shaped housing 28 surrounding an induction opening or port in the bottom of the tank 10. When the pum is in 0 eration, the water is driven throu ii the in uction opening with great speed, t e air being forced with the water or other liquid into the tank 10. As soon as a sufiicient quantity of Water has accumulated in the receiver 10 of this form of construction, a valve 29 in a return conduit 30 is opened and the liquid returns to the pump 25. In this way the water is used over and over again for air compression purposes. This is simply another form of construction whereby air may be compressed through the employment of a liquid vehicle.

Attention is called to the fact that in the form of construction shown in Fig. 1 the supply tank 13 may be dispensed with, and the conduit 12 connected directly with the pipe or conduit 7.

acac a Having thus described my invention, what I claim is:

The combination with a receiving tank, a supply tank, a centrifugal pump arran ed to take water from the supply tank an discharge it into the receiving tank, the said pum comprising a casing, a hollow rotatable 1m e ler located within the casing, a water in uction conduit connected with the casing and communicating with the impeller on one side, open-ended air inlet nozzles connected with the impeller on the opposite side from the induction conduit and extending throu h the casing to an air opening, the sald nozz es being radially dis osed rotating with the imeller, whereby t e air and water enter the impeller from opposite directions and are forced together into the receiving tank.

In testimony whereof I afiix my signature in presence of two witnesses.
