Specification of Letters Patent.
"Patented Aug; 3, 1915.
. Application'filed Deoember14;-1911. -Seria1No. 665,743.
the following to be a full, clear,,and exact description of the same.
This invention has been devised for the purpose of providing means whereby hydraulic rams may be cleared from matter choking the delivery pipe and valve, or the air dome and its valve and the waste pipe with a minimum of trouble and without any necessity for disconnecting any of the parts or for stopping the flow of water.
The invention consists in forming the top of the air dome with an opening which is normally kept sealed and providing it with an air inlet valve through which air under pressure may be introduced into the dome. A second air inlet valve is arranged in the waste pipe of the ram through which also, air under pressure, may be introduced into such pipe.
The opening in the top of the dome will allow for the dome being opened and cleared of any dirt or obstructions within it by the rush of the water that would then pass through the dome, and then be reclosed; while the air inlet valve thereon will provide for air being pumped into the top of the dome to force the water level down and to provide the necessary air pressure in the dome for the working of the ram. Likewise the air valve upon the waste pipe will provide for air being forced into such pipe to clear it of any dirt or other obstructions preventing the proper working of its outflow valve.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of a ram constructed according to this invention, the valves and valve fittings being shown in elevation. Fig. 2 is an enlarged sectional elevation of the top of the air dome and the valve in position therein.
A is the air dome; B the main flow pipe and C the waste pipe having the outlet gravity valve '0 all arranged the usual relative and operative positions.
In this invention the air dome A is formed with the openingD in its top into which opening a bush E is secured by means of the nut F.
passage G into the dome isthus provided. This passage is sealed by the, hollow =screw plug'H which. plug is provided with qthe air valve J opening through it. 'This valve is of any approved construction and preferably. such as will normally keep closed and will open when air is forced into it so as to allow the air to pass through. In the drawings the valve represented is of the ordinary pneumatic tire type of valve adapted to receive the flexible union of an air pump.
K is the second air valve of similar construction which is fitted into the waste pipe G at a point close to the dome A in order t me that air may be forced through it into such V pipe.
In operation, by unscrewing the plug H and removing it and the valve.
The inside of the dome may then be inspected and any matter removed or stirred up by inserting a tool through the opening in the bush E. The water flowing through the main B will then flow up through the dome and carry the dirt and other matters out through the top of the dome or along the waste pipe. The opening may then be closed and sealed by reinserting the screw plug H, after which air may be pumped in through the valve J to provide the required air pressure in the dome.
When the valves J and K are not being used, they may each be covered and protected by a cap M placed thereon.
The construction and fitting of the valves the air dome may be opened departing from the spirit of this invention and it is to be understood that I do not wish to confine myself exclusively to the means for carrying outthe invention described herein and shown in the drawings.
What I do claim as my invention and sire to secure by Letters Patent is I 1. In a hydraulic ram, the combination of a waste pipe having an outlet valve; an air dome communicating therewith at a distance from said valve, and having an opening at the upper part thereof; an inwardly and outwardly threaded hollow bush in said opening and having a shoulder engaging the inner face of the dome; a nut screwed to and engaging the outer threads of the bush the outer face of the dome and clamping the plug in said opening; a hollow screw plug screwed in the hollow bush; and an inwardly opening normally closed valve in the outer threads of Qopies' 0t this patent may be obtained for the outer face of the dome and clamping the plug in said opening; a hollow screw plug the bush and engaging screwed in the hollow bush; an inwardly opening normally closed valve in said plug and having a threaded end for the reception of a pump-connection; and a protecting cap placed over said valve and resting on the hollow screw plug. 7 a
In testimony whereof I have signed this I specification in the presence of two subscribing witnesses.
