Specification of Letters Patent.
Patented Feb. 3, 1920.
Application filed June 17, 1919. Serial No. 304,842.
To all whom, it may concern:
Be it known that I, BENJAMIN JENKINS, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented new and useful Improvements in Flushing Devices for Lavatory-Bowls, of which the following is a specification.
The device which is the subject matter of the present application for patent has been designed for the purpose of flushing out and removing obstructions from the overflow of lavatory bowls, basins and similar fixtures, and the invention has for its object to provide a very simple and highly efficient device for this purpose, which can be easily attached and made ready for use, and also readily removed.
The object statedis attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.
In the drawing,
Figure 1 is an elevation of the device showing its application, and
Fig. 2 is an enlarged vertical section thereof.
Referring specifically to the drawing, 5 denotes a bowl, basin or similar lavatory appliance having a bottom outlet 6 and an overflow opening 7 leading to an overflow channel 8, which latter communicates with the outlet. This is a. well known structure, and as nothing is claimed therefor, a detailed description is not necessary. The invention is applicable to anyordinary bowl having an overflow which opens into the outlet.
The flushing device is in the form of a cylindrical plug 9 having a diameter to enter the basin outlet 6. The top of the plug is fitted with a nipple 10 for attachment of one end of a flexible hose 11 having its other end connected to the spigot 11 from which the water supply to the bowl is obtained.
The plug 9 has a central water channel 12 closed at the top and open at the bottom, and surrounding this channel a water chamber 13 is formed in the wall of the plug. This chamber is continued across the top of the plug, as shown at 1 1, and it is here in communication with the water inlet nipple 10.
The length of the plug 9 is such that it extends down into the outlet 6 past the point where the overflow channel 8 opens into the latter, and above and below this point, the plug is enlarged diametrically as shown at 15 and 16 to seat in the outlet with a water-tight fit. Between the enlargements 15 and 16, and also above the enlargement 15, the diameter of the plug is such that it is spaced from the wall of the outlet. Above the enlargement 15 the plug 9 has side ports 17 from the outer surface thereof into the central water channel 12, and from the water chamber 13 extend ports 18 which open through the side of the plug between the enlargements 15 and 16.
hen the plug 9 is inserted into the outlet 6 and the water is turned on, the water enters the chamber 13 escapes therefrom through the inside ports 18 into the overflow channel 8, and passing up the latter it flows through the opening 7 into the bowl 5, from which latter it passes into the space between the upper end of the plug and the wall of the outlet, above theenlargement' 15, and escapes through the ports 17 into the channel 12, and as the latter is open at the bottom and communicates with the outlet below the point where the overflow channel enters, the water is allowed to escape into the waste pipe connected to the outlet.
It will be seen from the foregoing that there is a continuous circulation of water through the overflow, with the result that all obstructions are dislodged and discharged into the bowl from which they escape through the outlet of the latter. The device is very simple and readily applied or removed, and it effectually serves the purpose for which it is designed.
1. A flushing device comprising a plug having a water channel opening through one end thereof, with ports leading from the side of. the plug into the channel, the plug also having an internal water chamber, and ports leading from said chamber and opening through the side of the plug, and a water supply connection to the chamber.
2. A flushing device comprising a plug having a water channel opening through one end thereof, with ports leading from the side of the plug into the channel, the plug also having an internal Water chamber, and ports leading from said chamber and 0pening through the side of the plug, said plug 5 being enlarged diametrically on opposite sides of the second-mentioned ports to shut ofi' therefrom the flow t0 the first-mentioned ports, and also to shut off the flow from the second-mentioned ports past the plug, and a Water supply connection to the chamber. 10
