EALBERT B. HALVOBSEN, OI CHICAGO, ILLINOIS, ASSIGNOB TO SULLIVAN MACHIN- ERY OOMIPAIIY, A CORPORATION OF MASSACHUSETTS.

PRESSURE-FLUID LIFT PUMP.

Application med m 27, 1917. Serial :0. 188,171.

HALVORSEN, a citizen of the United States,v

' residing at Chicago, in the county of Cook 5 and State of Illinois, have invented certain new and useful Improvements in Pressure-Fluid Lift Pumps, of which the following is a full, clear, and exact specification.

My invention relates to pressure fluid lift pumps. i

It has for its object to. bring about a quicker and more thorough mixture of'the pressure fluid and the Iiquidto pumped, in such a manner as to increase thecapacity and efficiency of the system. More specifically, my invention has for its object to provide, an improved pump so dis osed with res ect to the supply of liquid to pumped and so delivering the pressure fluid thereto,

1 as to insure a quick and thorough mixture of the pressure fluid and liquid and thereby increase both the capacity and efliciency of the pump. A still further object of my invention is to provide an improved pump which is adapted to be readily inserted in or removed from the liquid supply line in such a manner as to facilitate the installation of the pump or the removal of the same whenever desired, as for instance during cleaning of the system.

In the accompanying drawings, I have shown, for urposes of Illustration, one embodiment w ich my invention may assume in practice. I

In this illustrative construction, I have shown a liquid supply pipe connected to a suitable riser 1, having a liquid receiving elbow 2 at its lower end and having at its upper end a discharge portion 3, herein, but not necessarily, removable and preferably slightly reduced in cross section to form a choke or venturi. Disposed within this riser is my improved pump.

This pump is provided with a suitable inlet 4 removably attached, as by threading.,-to a removable bottom plate 5 disposed -in an enlargement or extension 6 formed at the bottom of the, elbow 2, the'member 5 being suitabl attached to the extension, as by means 0 bolts 7. As illustrated, the .pump roper is also suitably connected, as throug an extension 8 of uniform and preferably restricted diameter, with the member 5, the lower end of the extension 8 preferably being also threaded in that member or formed integral therewith. Disposed above this extension 8, is a portion 9, preferably of circular cross section and conical form increasingin diameter toward the upper end of the elbow 2, and preferably imperforate, as shown, while disposed above this portion 9 and with its polnt of greatest diameter adjacent the outlet of the elbow 2,i. e., adjacent the lower end of the vertical section of the riser 1, is the hollow air discharging portion 10 of thepum which, as shown, is conical externally, an preferably internally, and hollow, and provided with a dispose throughout its length and adapted to deliver pressure fluid laterally and in an upward direction into the liquid surrounding the pump.. As illustrated, the upper end of this portion 10 of the pump is preferably also suitably sealed, as in a well known manner by a ca member 12 threaded in the upper end 0 the member 10.

the pump is delivered in successive streams into this relatively thin stream of liquid before it has materially increased in thickness and in an upward direction in such a manner that an exceedingly quick and thorough mixture oremulsion of the pressure fluid and liquid is obtained, which in practice has been found to increase materially the capacity and efliciency of the system. It will also be evident that through the rovision of my im roved construction inclu ing the removab 0 section 3, sections of diiferent throat area may be substituted when desired to enable the pum to operate at its greatest efiicienc and t at whenever it is desired the mem er 10 may be readily withdrawn by simpl removing the late 5, the process of instal in the pump eing likewise facilitated. I, ese and other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

While I have in this a plication specifically described one embo iment which my lurallty of series of air outlets 11 ply..nozzle connected to said riser member and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said riser and discharging into said riser member only in the portion thereof beyond said inlet. v

p 2. In an air lift pump, the combination with'a riser member provided with a lateral inlet for fluid to be pumped, of an air sup- .ply nozzle connected to said riser member and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said riser and having the portion which extends beyond said inlet perforated at longitudinally spaced points to provide for pumping fluid discharge, said riser and said air supply nozzle co-operating to form between them a passage whose cross sectional area is a minimum adjacent the lowest perforations and increases in cross sectional area thereabove.

3. In an air lift pump, the combination with a riser provided with a lateral inlet for fluid to be pumped, of an air supply nozzle connected to said riser and extending within it past saidinlet in a direction transverse to said inlet and longitudinal to said riser and provided with multiple perforations in the portion which extends beyond said inlet.

4. In an air lift pump, the combination with a riser having a uniform bore and provided with a lateral inlet for fluid to be pumped, of an air supply nozzle connected to said riser and exten ing within it past said inlet in a direction transverse to said inlet and longitudinal to said riser and havin the portion which extends beyond said mlet tapering in the direction of flow and proed with multi le perforations.

5.'Inan air .li pump, the combination with a riser provided with a lateral inlet for fluid to be pumped, of anair supply nozzle connected to said riser and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said riser and provided with multiple perforations in'the ortion which extends beyond said inlet and said inlet relatively reduced in transverse section.

6. In an air lift pump, the combination with a riser member provided with a lateral inlet for fluid to be pumped, of an airsupply nozzle connected to said riser member and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said riser and having the portion which extends beyond said inlet perforated at longitudinally spaced points to provide for pumping fluiddischarge, said riser and sai air supply nozzle cooperating to form between them a passage whose cross sectional area is a minimum adjacent the lowest perforations and increases in cross sectional area thereabove, therebeing a Venturi section arranged at a point above said discharge perforations, a I

7. In an air lift pump, the combination with a riser provided with a lateral inlet forfluid to be pumped, of a detachable air supply nozzle connected to said riser and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said riser; and provided with mulf.

tiple perforations in the portion which e ttends beyond said inlet.

8. In an air lift pump, the combination with a riser pipe section provided with a lateral inlet for fluid to be pumped, of a detachable air supply nozzle connected to one end of said section and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said section,

having the portion opposite iii and a Venturi section detachably connected to the opposite end of said section.

9. In an air lift pump, the combination with a riser ipe section provided with a lateral inlet or fluid to be pumped, of a detachable air supply nozzle connected to one end of said section and extending within it past said inlet in a direction transverse to said inlet and longitudinal to said section.

In testimon whereof Iaflix my signature.
