SUCTION PUMP Filed March 9, 1937 2 Sheets-Sheet l Inventor view/at Attorneys A. FONTENOT Sept. e, 1938.
SUCTION PUMP Filed March 9, 1957 2 Sheets-Sheet 2 I Inven ior 2077/28 noi' Attorneys Patented Sept. 6 19 38 UNITED STATES 1 Claim.
The present invention relates to new and useful improvements in suction pumps for use particularly in removing obstructions from clogged drain pipes and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arrangement of parts through the medium of which pipes of considerable length may be expeditiously cleaned or opened with a minimum of labor.
Another very important object of the invention is to provide a pump of the aforementioned character embodying a novel construction and arrangement of base and suction cup for providing a leak proof joint or connection between the pump and the pipe to be opened.
Other objects of the invention are to provide a pump of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in side elevation of a pump constructed in accordance with the present invention.
Figure 2 is a view in vertical section through the invention.
Figure 3 is a view in horizontal section through the base, taken substantially on the line 3-3 of %igure 4 is a detail view in elevation, showing the discharge neck or spout.
Figure 5 is a detail view in elevation of the hinged check valve for the discharge spout.
Referring now to'the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a barrel I of any suitable metal having a cap 2 threaded on its upper end. The cap 2 is provided with air vents 3. Extending slidably through the cap 2 into the barrel is a rod 4 having fixed on its upper end an operating handle 5. Fixed on the lower end of the rod 4 for reciprocation in the barrel I is a piston B. A coil spring 1 encircles the rod 4 and rests on the piston 6 for cushioning said piston against the cap 2 on the upward stroke of the pump. A coil spring 8 encircles the rod 4 and rests on the cap 2 for cushioning the handle 4 on the downward stroke of the pump.
Projecting from the lower portion of the barrel I is a discharge spout 9 having mounted on its outer end a seat In of suitable material. The reference numeral II designates a check valve for the discharge spout 9 which is provided with an arm I2 which is pivoted on a bracket I3 which projects from the barrel I. The check valve II is engageable with the seat I0 and said check valve is provided with a face I4 of suitable material. A spring I5 yieldingly urges the valve toward closed position.
Threaded into the lower end of the barrel I is a substantially dome shaped base I6 of suitable metal having threaded thereon a bottom I'I provided with an inlet opening I8. Mounted on the bottom I! is a gasket I9 of suitable material, such as leather or rubber, having an opening 20 therein aligned with the opening I8. A check valve 2| is provided for closing the openings I8 and 20, said check valve 2| being of leather, rubber or other suitable material. Check valve 2| comprises a tongue 22 secured to the gasket I9 by suitable elements 23. Further, the check valve 2| is stiffened and weighted by a metallic disc 24 secured thereon.
Mounted on the lower end portion of the barrel I is a rubber suction cup 25. A suitable clamp 26 secures the suction cup 25 on the barrel As illustrated to advantage in Fig. 2 of the drawings, the suction cup 25 encloses the base I6 and extends therebelow.
It is thought that the manner of using the device will be readily apparent from a consideration of the foregoing. The bottom ll of the base I6 is engaged with the mouth of the pipe to be opened or with the basin, sink, bowl or the like to which said pipe is usually connected. The rubber suction cup 25 engages the sink, basin or bowl for providing a leak proof connection in a manner which is thought to be well understood. As the piston B is drawn upwardly in the barrel I the water and other matter in the pipe is sucked past the check valve 2| into the base I6 and the barrel I. On the downward stroke of the piston 6 the check valve 2| closes and the check valve II is opened as the water and other matter is discharged through the spout 9. Of course, the valve II is closed on the upward stroke of the piston 6. The substantially dome shaped base I6 functions as a support for the cup 25 in a manner to permit the creation of an exceedingly strong vacuum or suction without collapsing said cup 25.
It is thought that the many advantages of a 55 ed for reciprocation in said barrel, a rigid substantially dome shaped base mounted on one end of the barrel, a dome-shaped flexible suction cup embodying a neck secured to said end of the barrel and enclosing the base, said suction cup being spaced outwardly from the walls of the base and projecting beyond the bottom of the base, said base constituting an internal support for the suction cup, said base having an intake opening in its bottom, and an inwardly opening check valve mounted in the, base for. controlling .said intake 10 opening.
