Application filed January 28, 1918. Serial Ito. 214,179.
To all whom it may concern Be it known that ll, DAVID E. GULicK, a citizen of the United States of America, residing at 84:5 Sutter street, San Francisco, in
5 the city and county of San Francisco and State of California, have invented new and useful Improvements in Ball-Cocks, Other-' wise Known as Float-Valves, of which the following is a specification.
This invention relates to ball cocks, otherwise known as float valves, and its object is to produce a device noiseless in operation giving a full flow under all pressures and at the same time simple in construction and positive in operation. p
In carrying out the invention, I construct a casing. This casing is divided at a convenient point by a piston or movable diaphragm-into two chambers, the lower chamber having an inlet opening for connection to service supply and also a discharge outlet controlled bya valve.
The upper chamber has an open waterway connecting it with the lower chamber. It also has a waterway connecting with the discharge outlet, said waterway being controlled by a valve.
This last mentioned valve is the initiating valve and is acted upon by a lever with a rod and float connected thereto.v The opening and closing of the initiating valve is caused by the lowering and raising of thefloat but all other operations are automatic.
When referring to upper and lower chambers it will .be understood that this refers only to the position of the device in the drawing as it may be set in any convenient position for practical use.
I have illustrated my invention in the accompanying two sheets of drawings.
Figure 1 is a top view of the device.
' Fig. 2 is a longitudinal .section taken at the line 2, 2 of Fig. 11 J Fig. 3 is a longitudinal section showing valve 5 is secured to diaphragm 3 by means of a nut 6. To the lower side of main valve 5, there is attached a washer 7 and guide 8.- 5t Theinitiating valve 9 is fitted with washer waterway F.
the casing modified with a piston instead of.
10 and guide stem 11. The initiating valve 18 held in place by cap 12 andis acted upon by lever 13 to whichis attached rod 14 and It will be seen that diaphragm 3 divides the casing or main chamber into two subchambers C and D,and that these sub-chambers are connected by waterway E and that they are also connected with outlet B by means of waterway or bypass F, said waterway F being controlled by initiating or auxiliary valve 9; Guide stem 11 passes through waterway E and moves out and in upon the opening and closing of initiating valve 9, and, therefore, insures that said waterway cannot become clogged or closed by any sub stance lodging over the open ng. A further purpose of guide 11 is to partially close waterway E so that the flow through said waterway will not equal the flow through A is the service or inlet connection to chamber O and B is the discharge outlet from said chamber.
The operation of the valve is as follows The valve is placed in position for filling the tanlr or other receptacle and is adjusted so that when the initiating valve 9 is closed the float 15 will rest on the surface of the water at'the'level it is desired to maintain, then when the level of the surface of the water falls, the float drops also, following it and thereby opens initiating valve 9, relieving the pressure in chamber D. Imme diately the pressure in chamber C lifts diaphragm 3 and main valve 5, which is attached thereto, thus forcing the water from chamber 1) out through waterway F and at the same time opening dischargeoutlet 1B.
- The water will continue to flow through the valve until the level of the surface of the water has lifted the .fioat15 up to the point i where it closes the initiating valve 9 at which time water from chamber O passes through waterway E up into chamber D and vforces diaphragm 3- down until main valve 5 contact? with its seat and closes discharge outlet The operation of valve as illustrated in Figs. 3 and 4' is identical with the fore- -going,--the casing bein modified to adapt it for-use with piston an a piston being used instead of I a flexible diaphragm,-pistons and diaphragms being well known substitutes for each other and their. action being;
identical and Well understood, they need not further be described.
With the object in view and to the end of securing quietness in operation I have avoidedall sharp corners and angles in the main waterway and have avoided a raised seat for the main valve,-said seat being conical or slightly hollowed with a conical or rounded washer on main valve seating thereon. The water flows full capacity until the initiating valve is closed, whereupon the main valve closes immediately. The fore going manner of construction and operation prevents the shrill whistling and long continued hissing sound which is so objectionable. especially with a water closet tank while it is filling and the hall cock or float valve is closing off.
Another novel feature is the construction using an automatically movable stem operating through the. waterway leading to the closing chamber. which prevents any particle from lodging over the opening and thus insures that the said waterway must remain open always.
I am aware that ball cocks or float valves have previously been made using piston or diaphragm, but. believe I have embodied novel and new features of arrangement and construction which are in improvement over such others.
Having thus far described my invention in full, clear and exact terms as required by law, and believing that it comprises novel, useful and valuable improvements in the art to which it pertains, I claim and desire to secure Letters Patent of the United with said waterway, a float operated initiatmg valve controlling the opening and closmg of said bypass, a stem attached to the initiating valve and within said waterway and movingwith initiating valve thus keeping the said waterway free of obstructions.
2; A float operated supply valve comprising a casing, a movable partition dividing said easing into two chan'ibers, one of said chambers having an inlet port and a main discharge outlet, a main valve attached to the aforementioned partition and controlling the main discharge outlet, at waterway joiir ing the aforementioned two chambers, a bypass joining the discharge outlet with said waterway: a float operated initiating valve controlling said bypass, a member attached to the initiating valve and within said \\'aterwa v and moving with the initiating valve thus keepingthe said waterway free of obstructions.
3. A supply device comprising a chamber with an inlet and a discharge outlet, within the atorenientionedchamber a movable main valve dividing said chamber into two subchambers,-a waterway joining said. subchambers, a bypass joining said waterway with the discharge outlet, an initiating or auxiliary v'alve controlling said by-pass, said initiating or auxiliary valve having an extension or stem attached and moving therewith and being within the said waterway.
4. Tu a float operated valve, a casing having an inlet and an outlet, a partition in the casing and ope a ted by fluid pressure from above and below thepartition, a valve suspended by and movable with the partition,-
said partition dividing the easing into two chambers, waterways leading to said chambers, an initiating valve having a stem working in one. of the waterways, and a float device for operating the initiating valve.
5. In a float operated valve, a casing having an inletand an outlet, a fixed partition dividing the easing into a closing chamber and an inlet chamber and having a movable central portion, a valve suspended by said portion and working in ,one of said chambers, said latter chamber having a waterway, an initiating valve having a stem partially closing the said waterway, and a float device for operating the initiating valve.
