STANISLAW USTRZYCKI AND JOSEPH BUKOLA, OF CHICAGO, ILLINOIS.

PLUNGER.

Specification of Letters Batent. Patented lIay 11, 1920.

Application filed November 1, 1919. Serial No. 335,171.

To all whom it may concern:

Be it known that we, STANISLAW Us- TRZYGKI and JOSEPH BUKOLA, citizens of P- land, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Plungers, of which the following is a specification.

The object of the invention is to provide a simple and effective means whereby obstructions may be removed from drain pipes of sinks, bath tubs, closets and the like, under conditions involving the minimum effort and loss of time upon the part of the op erator, and to this end the same consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, it being understood that changes in form, proportions and details may be resorted to within the scope of the claims without departing from the principles involved.

In the drawing:

Figure l is a vertical sectional view of the clean out pump applied in the operative position to a sink outlet, the piston being shown in full lines in its depressed and in dotted lines in its elevated position.

Fig. 2 is a detail sectional view showing the application of the device to a closet,

and embodying anchoring means peculiarly adapted for that purpose.

Fig. 3 is a plan view of the grapple shown in its operative position in engagement with a sink strainer.

The casing embodies a cylinder 11 and is adapted by reason of a foot 12 provided with a rubber or other elastic gasket 13 to be seated either upon a, sink bottom 14: around the perforated outlet 15 thereof or in contact with the inner surface of a bowl 16 shown in Fig. 2, said gasket having both a bottom and a peripheral bearing surface to adapt it for these several purposes. Mounted in the cylinder 11 is a plunger 17 with which is connected a strong spring 18 anchored at its lower end to a transverse bar 19 which in the construction as illustrated consists of a shaft provided at one end, outside of the casing with a hand wheel 20 and having associated therewith locking means consisting of the ratchet 21 and pawl 22, so that said shaft may be secured in an adjusted position. Grappling arms 23 may be associated with the device when it is to be used in connection with sink outlets and similar devices for engagement with the openings in the grating or strainer 15, said arms being connected with a ring 24 which in turn is attached to the end of a chain 25 reeled upon a drum 26 carried by said shaft 19.

In the construction illustrated in Fig. 2, when the device is adapted for application to a closet bowl, the grappling arms 27 consist of rods having terminal hooks 28 for engagement with the bowl rim 29, turn buckles 30 being employed to secure the forcible depression of the casing so as to properly seat the foot 12' upon the inner surface of the bowl.

Also connected with the plunger 17 is a rack 31 extending through a guide opening in the head 32 of the cylinder and engaged by a mutilated gear 33 adapted for actuation by a worm 3 1 engaging a worm gear 35 secured to the mutilated gear or the spindle which carries the same, said worm having its shaft 36 fitted with a hand wheel 37 by which the operator may communicate motion through the worm and worm gear and the mutilated gear to the rack to. elevate the plunger in opposition to the tension of the spring 18. When the elevation of said plunger has proceeded until the blank portion 38 of the mutilated gear is brought to a position facing the rack, so as to; engage the teeth of the mutilated gear fromthe rack, the plunger is released to be forced downward by the spring to expel any obstructing accumulation in the pipe in communication with which the casing has been arranged. Obviously the operation of the plunger may be repeated by a continuous manipulation of the hand wheel 37 until the obstruction has been displaced.

What is claimed is:

1. A clean out pump having a cylinder and a spring advanced plunger, and means for securing the same with the cylinder in airtight communication with a pipe to be cleaned, a rack connected with the piston and a mutilated gear engaged with the rack and adapted upon retraction of the same to release the piston for actuation by its spring.

2. A clean out pump having a cylinder and means for securing the same in air-tight communication with a pipe to be cleaned, a spring advanced piston arranged in said cylinder, a rack connected with the piston, mutilated gear in engagement with the rack for retracting and releasing said piston and means for actuating the mutilated gear.

3. A clean out pump having a cylinder and means for securing the same in air-tight communication with a pipe to be cleaned, a spring advanced. plunger in the cylinder, a rack connected with the piston, a mutilated gear in engagement with the rack and adapted to release the same upon retraction of the piston, and means consisting of 10 a Worm and Wor-mgear for communicating rotary motion to the mutilated gear.

In testimony whereof We ME); 0111' signa- 'tures.
