Application April 16, 1945, Serial No. 588,615
2 Claims. (Cl. 1 -255) This invention relates to improvements in sucliln plungers for clearing clogged drains or the An object of this invention is to provide an irnproved suction plunger which igsimp-le in construction and will automatically return to its normal position, the device including inner and outer suction cups, said cups cooperating with each other to provide an eiiicient suction action for quickly cleaning or loosening drains in various types of xtures.
Another object of this invention is to provide a device of this kind which, by reason of the novel construction thereof, is more'powerful in its operation than conventional suction cups.
With the above and such other objects in view, as may hereinafter more fully appear, I have invented the device shown in the accompanying drawing, in which:
Figure 1 is a vertical section, partly rbroken away and in detail, of a suction pump constructed according to an embodiment of this invention.
Figure 2 is a sectional View taken on the line 2 2 of Figure 1.
Referring to the drawing, the numeral Il) designates generally an outer resilient. cup member which is formed at the lower large open end thereof with a flange or rib Il. rThe cup member I9 is formed at the upper end thereof with a boss I2 having an opening I3 therethrough, the purpose for which will be hereinafter described.
An inner resilient cup member I4 is disposed within the outer cup member I B, and opens downwardly. 4'Ihe inner cup member I4 terminates at its lower open end adjacent the lower end of the outer cup member I0, and is secured to the inner yside of the outer cup vmember ID, as indicated at The inner cup member I4 may be vulcanized or otherwise rmly secured to the outer cup member I so as to form substantially an integral bond. The inner cup member I4 is provided with an upwardly extending boss I6, and, as shown in Figure 1, when the device is in normal position the upper end of the inner cup member I4 will be disposed in downwardly spaced relation to the upper end of the outer cup member I0. The lower end of a plunger rod I1 is threaded into the boss I6, and
slidably engages through the opening I3 of the boss l2.
A spring IB is positioned about the plunger rod Il, bearing at its lower end against'the upper end of the boss I2, and bearing at its upper end against a transversely extending pin I Slengaging through the rod Il,
In the use and operation of this device, the cup member Hl has the flange or rib II thereof engaged about the drain opening. The plunger rod Il is then moved downwardly so as to flex and distort the inner cup member I0, as shown in dotted lines in Figure 1. Pressure in a downward direction on plunger rod I'I will compress the spring I8 so that the outer cup member I0 will be tensioned against the surface of the fixture about the opening. As the inner cup member I feXes downwardly the air inside of this member will be forced downwardly and this air will provide a force for unclogging the drain. y
The plunger rod il may be worked up and down and as the plunger rod I1 is released the spring I3 will force this rod upwardly so as to return the inner cup member Id to substantially its normal position. In this manner the pump will operate automatically on its return stroke and, the downward pressure on the outer cup member II! will provide sufficient pressure to seal the flange I I about the drain opening.
The above is the preferred embodiment of my invention but it is to be understood that modifications may be resorted to that fall within the scope I of the claimed invention.
What I claim is: Y
1. A suction plunger comprising a resilient outer cup having an opening rand a boss about said opening, an inner cup secured at its lower end to said outer cup, said inner cup having an opening aligning with the opening of said outer cup, and a plunger rod secured to said inner cup and slidably engaging through said rst opening.
2. A suction plunger comprising a resilient outer `cup having an opening and a boss about said opening, an inner cup secured at its lower end to said outer cup, said inner cup having ank opening aligning with the opening of said outer cup, a plunger rod secured to said inner cup and slidably engaging through said first opening, a spring about said rod bearing at one end against said boss, and a spring tensioning member iixed relative to said rod and bearing against the opposite end of said spring.
