VICTOR W. HELAND EB, OF SAN PEDRO, CALIFORNIA.
Application filed November To all whom it may concern Be it known that I. Vroron W. HELANDER,
a citizen of the United States, and a resident phonic flow of a liquid from a receptacle and in such manner that the siphon can be broken and renewed at the will of the operator, thereby providing complete control of the exhaust of the liquid from the receptacle. c
I will d'escribeonly two forms of sipho n pumps embodying my invention, and will then point out the novel features thereof in claims. In the accompanying drawings Figure 1 is a view showing in vertical longitudinal section one form of siphon pump embodying my invention, with the parts thereof in position for exhausting the air from the barrel of the pump;
Figure 2 is a view similar to Figure 1, showing the parts of the pump in position for drawing a liquid into the barrel toinitiate the siphonic flow of liquid through the pump;
Figure 3'is a vertical sectional viewtaken on the line 33 of Figure 1;
Figure 4c is a a detail perspective view of the outlet valve embodied in the pump shown in the preceding views; v
Figure 5 is a horizontal sectional view taken on the line 5-5 of Figure 1;
Figure 6 is a fragmentary vertical sectional view showing a modified form of siphon pump embodying my invention.
Similar reference characters refer to simi lar parts in each of the several views of the drawing.
Referring specifically to the drawings, my invention in its embodiment as shown in Figures land 2 comprises a barrel 15, the lower end of which is interiorly threaded to receive a plug 16 having a bore 17 normally closed at its upper end by a flap valve 18 which is movable inwardly to an open positi on as illustrated in Figure 2, such open position being defined by a cage 19 secured 2, 1925.. Serial No. 66,407.
'to the plug 16. The plug 16 is shouldered as indicated at 20 to limit its inward securmg movement, and the lower end of the bore 17 is; enlarged and its walls screw threaded to receive an exteriorly threaded collar 21 having a flange 22 to which is secured a'cup V shaped filtering member Adjacent the upper end of the barrel 15 a discharge spout 2% is formed integral with the barrel and late "ally disposed,'with its vouter end constructed to provide an inclined valve seat 25 against which an outlet valve 26 normally rests toclose the nozzle.
shown in Figure i, this valve 26is in the form of an ovate disk, with the ends thereof'provided with recesses 27 which, as shown in Figure 3, loosely reccive'a cage 28 in such manner that the ca e functionsto support the valve for movement to open and closed positions, and because of the inclination of the valve seat 28 the valve-normally gravitates to closed position. The cage .28 is secured at its endsto the nozzle 24, and a portion of the nozzleis exteriorly threaded to receive a cup shaped connector 29 provided with a tubular expansion 30 exteriorly corrugated to receive one end of flexible tube 31. v Q i In the upper end of the barrel 15 is secured a broad plug 32 having a tubulareX- tension 33 exterior-1y corrugated to receive a bulb Si formed of rubber or other suitable material, while adjacent the plug 32 the barrel is formed with a tubular extension 35 shaped at its point of connection with the barrel'to provide a conical seat 86 normally engaged by a conical valve 37 provided with a stem 38, to the outer end of which is keyed a knurled head 39. .A spring 40 is interposed between the valve 87 and the head.
39 for normally urging the valve to closed pushing the valve head inwardly against the tension of the spring 4:0 the valve 87 will be opened. valve atmospheric air is supplied to the barrel through a port ll in the tubular extension 35. y
In operation, the filtering cup is adapted to be submerged in the liquid to be elevated, the filtering cup serving to strain the liquid and prevent entrance of solid particles into the barrel. With the cup submerged, the bulb 34.- is squeezed to the contracted position shown in Figure 1, thereby placing the air in the barrel under pressure to maintain the In the open position of the I ill) ly of the barrel through the nozzle Eat, it be mg understood that the force of the liquid will operate to open the outlet valve 26 so that the liquid can be discharged into the tube 31. \Vith this siphonie action once established it will be understood that the liquid will continue to flow through the pump until the siphon is broken. The siphon may be broken by opening the valve- 3? to admit atmospheric air to the barrel as has been described. In this manner any amount ot liquid can be discharged from the receptacle and the flow of the liquid terminated at the will of the operator through the manipulation oi the valve 37.
Referring now to Figure 6, I have here shown the upper end of the barrel 15 provided with a cap e2 upon which is slidably mounted the rod 43 of a plunger 44- reciprocable in the barrel by reciprocating the rod through a handle 45, The plunger 44- is adapted to take the place of the bulb 34: to create a negative pressure in the barrel 15, and the plunger is particularly designed for use in relatively large siphon pumps where a relatively high negative pressure is necessary to initiate the siphonic flow of the liquid.
Although I have herein shown and described only two forms of siphon pump each embodying my invention, it will be understood that various changes and modifications may be made herein without departing from 7 the spirit of the invention and within the spirit and scope of the appended claims.
1. A siphon pump comprising a barrel, a
plug in the lower end of the barrel having a bore constituting a liquid inlet for the barrel, a flap valve normally closing the inlet and opening inwardly, a cage secured to the plug for defining the open position of the valve, a filtering element detachably secured to the plug, a nozzle extending laterally trom the barrel and having an inclined valve seat, a cage secured to the nozzle, an oval shaped flap valve movable on the cage and normally engaging the seat to close the nozzle, said valve provided with notches loosely receiving the valve cage, a connector for housing the second valve and cage and detachably associated with the nozzle, a tubular extension on the barrel provided with an air inlet port, a valve disposed in the extension for controlling said port and normally urged to closed position, a plug disposed in the upper end of the barrel and having a tubular extension and formed with a bore comn'iunicating with the barrel, and a manually operable element connected to the extension for creating a negative pressure in the barrel.
2. A siphon pump comprising a ba "rel, a plug in the lower end of the barrel having a bore constituting a liquid inlet for the barrel, a flap valve normally closing the inlet and opening inwardly, a cage secured to the plug for defining the open position of the valve, an outlet nozzle extending laterally from the barrel and l'iaving an inclined seat, a flap valve normally engaging the nozzle seat normally closing the outlet nozzle and opening outwardly, a cage secured to the nozzle for defining the open position of the said valve, a tubular extension on the barrel provided with an air inlet port, a plunger valve disposed in the extension for controlling said port and normally urged to closed position, a plug in the upper end of the barrel having a bore communicating therewith, an extension on the plug, and a manually operable element connected to the plug ex tension for creating a negative pressure in the barrel.
