1 Claim.
This invention relates to drain flushers and more particularly to flushing devices of the type by which drain or Waste pipes of sinks, urinals,
and wash and closet bowls or the like, are freed from clogging or obstructive matter through the medium of a forcibly injected stream of water.
It is an object of the invention to provide a device of the above stated character, in which the water stream is directed to the pipe to be cleaned, in a peculiarly effective manner. Another object resides in providing a flushing device inclusive of a cup capable of deformation, for its application to fixtures of varying forms and contours. A further object is to provide in a flushing device, a connection inclusive of an interchangeable member which renders the device applicable to faucets of either the plain or screwthreaded type. Another object is to provide a connection applicable to faucets of different sizes,
and still other objects are to be found in details of construction as will be fully set forth in the course of the following description.
In the accompanying drawing in the several views of which like parts are similarly designated,
Figure 1 is an elevation, partially in section, showing the improved flushing device in its preferred form as applied to a water-faucet and a fixture to be flushed,
Figure 2 is a section on the line 22 of Figure 1,
Figure 3 shows a faucet of the screw-threaded type, with a correspondingly formed part of the connection of the flushing device, and
Figure 4 is an enlarged section taken on the line 44 of Figure 1.
Referring further to the drawing, the numeral 5 designates a water-faucet of conventional construction, having a plain or smooth-surfaced e0 spout 6 to which, in practise, the flushing device is applied, for the supply of water under pressure from the source with which the faucet is connected.
The flushing device comprises a cup I made of inelastic flexible metal which in an inverted position is attached at the end of a flexible tube 8 by which the device is connected with the faucet.
The tube as shown in Figure 1, consists of two sections 9 and Ill, detachably connected by a screw-threaded union l2 of conventional construction. The section Ill of the tube as shown in Figure 1, is formed for the insertion of the smooth-surfaced spout of the nozzle, but should the spout of a faucet adjacent the fixture to be flushed be of the screw-threaded type as illustrated at ill in Figure 3, the section It) may be replaced by another similar section having a swiveled screw-threaded nut M for its application to the faucet. It will be apparent without further illustration that the sectional construction of the 5 tube is of advantage in lengthening the connection by the use of an intermediate section or that in case the device is invariably used in connection with a faucet of either the plain or screwthreaded type, the tube may be made of one con- 10 tinuous piece. In order to render the connection applicable to plain faucets of different diameters, the end-portion of the tube may be stepped internally as shown in Figure 4, to provide two, three or more sockets l5 of gradually decreasing 15 diameters into which the correspondingly formed spout of the faucet may be inserted.
Connected with the tube at its end at which it is attached to the cup, is a nozzle it which extends to a point in close proximity to the plane 20 of the rim of the cup at which it engages the surface of the fixture to be flushed as will hereinafter be more fully described.
The end portion of the nozzle is contracted as at ll, and its extremity I8 flares outwardly from the 25 point of contraction to produce a Venturi effect upon the water stream causing it to issue from the nozzle with increased force and intensity.
The cup is made of flexible metal such as copper so that it may be laterally deformed under 30 manual pressure, as indicated in broken lines in Figure 2. The edge of the cup is inserted into a correspondingly formed groove of a rim I9 made of rubber or other elastic material which in practise, forms a contact ring by which the cup is held 35 in fluid-tight engagement with the surface of a fixture 2E! to which the flushing device is applied.
The ring being elastic, remains constantly in place on the cup in any form thereof under laterally applied pressure and in case of wear or 4.0 breakage it is readily removed and replaced by another similar ring.
In the use of the device, the rim of the cup is pressed against the surface of a urinal, sink, wash bowl, closet bowl or other fixture over the open- 45 ing 2! of a drain or waste pipe 22 to be flushed and while thus being held in its operative position, the cup may be subjected to pressure in a lateral direction, to cause it to conform with the contour of the surface of the fixture. 59
After the tube has been applied to the spout of a water faucet in any of the manners shown and described, the faucet is opened and water under pressure is directed in a stream into the opening of the waste or drain pipe with a force greatly increased by the Venturi form of the nozzle and by its position in close proximity to the opening 2|. Any surplus or water rising in the fluid-tight cup, will cause a compression of air which further adds to the intensity with which the water stream is injected into the opening of the drain.
It has been found in actual use, that the device constructed and applied as herein described, can wash out an entire sewer system with 60 to 110 pounds of water pressure, keeping it clean and sanitary at all times and rendering the use of cleaning compounds unnecessary under most conditions.
Where acloset fixture is to be opened the cup is inserted into the opening therein and the periphery of the ring [9 engages the side of the opening. Since the openings in closet fixtures are seldom round, the ring and the cup must bend to conform to the shape of the opening and the metal cup has therefore been made of readily bendable material, such as copper, so that it may assume forms such as that shown in Figure 2. The lower surface of the ring is rounded to facilitate its insertion into an opening and its diameter is greater than that of the cup so that it alone will contact with the Wall of the opening.
What we claim and desire to secure by Letters Patent is:
A drain flusher comprising a metal cup laterally flexible to conform with varying contours of fixtures to be flushed, a flexible resilient contact ring of greater diameter than the cup and attached to the rim of the cup, a nozzle in the cup, and a conduit to connect the nozzle with a source of Water-supply.
