F. E. THARP DRAIN PIPE CLEANER Filed April 15, 1935 April 7, 1936.
3mm fianklz Thar '17 Patented Ap 7, 1936 UNITED STATES PATENT OFFICE DRAIN PIPE CLEANER Frank E. Tharp, Worland, Wyo.
Application April 13, 1935, Serial No. 16,233
1 Claim. (Cl. 4-256) This invention relates to a drain pipe cleaner, and it is primarily an object of the invention to provide a device of this kind whereby a drain pipe may be effectively cleaned by the use of water pressure from a faucet.
Another object of the invention is to provide a device of this kind including a reversible nozzle whereby the scope of use of the device is materially enlarged.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved drain pipe cleaner whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:-
Figure 1 is a view partly in section and partly in elevation illustrating a drain pipe cleaner constructed in accordance with an embodiment of my invention and in applied position;
Figure 2 is an enlarged fragmentary detailed view taken through the outer end of the hose and through the associated head, the adjustment of the iliead being reversed to that illustrated in Figure Figure 3 is a view in perspective of the means herein disclosed for closing the overflow drain openings.
As disclosed in the accompanying drawing, I denotes a section of flexible hose of desired length, one end portion of which carrying a clamp 2 whereby said end portion may be effectively held against displacement after-being fltted over the nomle of a faucet I.
Securely fastened to and surrounding the opposite end portion of the hose I is a threaded ferrule l which permits detachable connection of said end portion of the hose to a head 5. This head I is made of a rubber compound or of other material as may be preferred and, as disclosed in the accompanying drawing, this head I5 is in the general form of a parabola having a flat end face 6. The head 5 has disposed axially thereof a bore 1 in which is tightly fitted a sleeve 8, the opposite end portions of which being threaded, as at 9, whereby the head 5 may be detachably engaged with the hose I and readily reversed as desired.
With the head 5 applied to the hose I with the rounded portion outwardly directed the same is in adjustment for use in cleaning the drain pipe of a lavatory, bath or laundry tub, etc. When the head 5 is engaged with the hose I with the flat face 6 outwardly directed, it is in adjustment for use in connection with the cleaning out of drain pipes leading from kitchen sinks or other relatively large drain openings.
In the accompanying drawing the device is shown as for use in connection with a conventional lavatory and before the water from the faucet 3 is allowed to pass out through the hose I, the usual drain I0 for the soap container is closed by a plug I I. This plug II is preferably of a rubber composition and is in simulation of a thumb screw. The overflow drain openings I2 in the bowl of the lavatory are also closed by a plate II. As herein disclosed, this plate I4 has a rubber facing I5 which contacts directly with the wall of the bowl and passing through the central portion of the plate I4 is a threaded shank I6. One end portion of this shank I6 carries a cross head I! whereby the shank may have proper anchorage to the wall of the bowl. The outer portion of this shank l6 has threaded thereon a winged holding or clamping nut I8. The outer end portion of the shank I6 is also preferably flattened, as at I9, the resultant flattened face serving as an indicator to show the position of the cross head I'l after it has been inserted through one of the drain openings in the wall of the bowl.
From the foregoing description it is thought to be obvious that a drain pipe cleaner constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
A device for cleaning out plumbing drains comprising a flexible hose, means at one end portion of the hose for securing the same to a faucet nozzle, the opposite end portion of the hose being threaded, a head'in the general form of a parabola havinga flattened end face, said head being of distortive material and having a bore disposed axially therethrough, and a sleeve tightly fitting in the bore of the head and extending from one end to the other with the opposite end portions of the wall of the sleeve being threaded for selective engagement with the threaded end portion of the hose.
