Filed Sept. 28, 1929 2 Sheets-Sheet 2 l v f/ll'l'l'l'l'fl 1 Ill-I Inventor A itomey Patented May 12, 1931 UNITED, STATES mm am or roansr nuns, NEW YORK DRAIN crriaimn Application med September 88, 1928. Serial No. 895,887.

This invention appertains to new and useful improvements in drain cleaners and more particularly to a device of this character which is used in connection with a fluid under pressure. 7

The principal object of this invention is to rovide a drain cleaner which may be rea ily connected to a faucet of the usual municipal water supply for flushing and clearin the drain.

Anot er important object of the invention is to provide a drain cleaner including means whereby fluid under pressure may be concentrated on the drain.

These and other important objects of the invention will become more ap arent as the invention is better understood rom the following specification and claims.

In the drawings:

Figure 1 represents an elevational view of the invention and a sectional view of a commode into which the device has been engaged.

' Figure 2 represents a sectional and partial sectional view of the drain cleaner in pressed 25 sealing engagement with the bottom of a sink for cleaning the drain thereof.

Figure 3 represents an end elevation of the cleaner looking toward the force cup structure.

Referring to the drawings, wherein like numerals designate like parts, it will be seen that the novel device includes an elongated hose 5, which is reinforced at its op osite ends as at 6 and 7, the end 6 being thic ened for receiving a faucet and rovided with a sleeve extension 8 for dlSPOSltiOIl around the faucet in the manner shown in Figure 2 so as to securely pack the connection to prevent loss of pressure. v

The end 7 of the hose is ada ted to be flexed over one end of a rigid tu e or pipe section 9. The opposite end of the ipe section 9 is to be disposed within the necl r portion 10 of the force cup 11. This force cup is of bell shape and when employed for clearing sink drains, the same is disposed with the nipple portion12 flexed inwardly. This entire cup is constructed of some heavy resilient material such as rubber and a V-shaped notch 13 is provided in the nipple 12 to permit it to flex to the rojected position as shown in Figure 1. he thickness of the walls of the nipple gradually tapered toward the free end and from the base of the on to the nipple end to impart flexibility t ereto. The drawings somewhat exaggerate the thickness of the walls of the .mpple as in actual practice-they may taper from-a thickness of onelieighth of an inch to one-sixteenth of an 1nc Obviousl when the device is employed on a clogged d i'ain in a sink, the positioning of the cup around the drain opening by pressing the bottom of the device in sealing engagement with the bottom of the sink and the sleeve 8 of the end 6 of the hose engaging the faucet, will not permit any of the pressure of the water su ply to become lost.

When it is desired to clear the'drain of a water-closet bowl, the nipple 12 is flexed outwardly as shown in Figure 1 and engaged in the drain canal of the commode. When the nipple is used in this capacity, it is simply wedged into the drain canal and the pressure of the water delivered through the hose 5 is concentrated through the area clogged.

While it is preferable that the cup 11 be manufactured of rubber, the same may be produced of any suitable material, as. may

e the hose 5 and the pipe section 9. Obviously the shape of the individual parts of the device may be modified without departing from the spirit and scope of the claims appended.

Having described the invention, what is claimed as new is z.

1. A drain cleaner comprising a hose section, a rigid pipe section for attachment at one end to one end of the hose, and a resilient force cup for. attachment to the'opposite end of the rigid pipe section, said cup being of bell-shape, said bell-shaped cup being provided with a normally inwardly disposed vnipple adapted to be flexed outwardly when the cup is to be used for clearing pipes into which it must project, said nipple being provifded' with a notch to facilitate flexing there 0 2. In a device of the class described, a resilient force cup provided with a flexible nipple adapted to be flexed within said cup or flexed to extend outwardly therefrom, de

ending upon the particular type of drain to Ea cleaned, and a V-shaped notch extending inwardly from the free edge of said nipple for facilitating free inward and outward flexing of said ni ple.

In testimony w ereof I afiix my si nature.
