CLEANING FEED-WATER REGULATORS.

Specification of Letters Patent.

Application filed January 22, 1908.

Serial N 0. 412,204.

To all whom it may concern:

Be it known that I, THOMAS KEENAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Cleaning Feed-VVater Regulators, of which the following is a specification.

This invention relates to means by which an inlet valve of a feed water regulator for a boiler or other appliance can be readily washed or flushed clean. In case of a boiler or the like the pressure therein can also be made to serve as a means for cleaning or blowing out any sediment that is lodged on the seat of the inlet valve.

This invention is set forth in the following specification and claim and illustrated in the annexed drawing in which- Figure 1 shows a cleaning feed regulator embodying this invention. Fig. 2 shows a modification.

The feed water regulator comprises an inlet pipe (1 outlet pipes l) b and a float 0 connected to an inlet valve e; these parts are not new. The new feature of the invention consists in providing the feed water regulator with a passage or channel f located below the inlet valve 6 and having an outlet cock or valve 9 at the end of the passage f. The passage or outlet f is formed by a division wall 7:: overhangin the outlet f, and inlet water from a wil carry any sediment contained therein to the inner end of said passage under the valve 6. Such sediment is prevented from being caught or trapped at such end of the passage under valve 6 as on opening valve 9 the current from inlet opening a will sweep about the end of the partition or division Wall 7c and wash away any accumulation or mud at the end of the passage under the valve 6. The feed water inlet a communicates with said passage f and when the out let valve g is opened the mud and other sediment which has accumulated under the autorn atio valve 6 will be flushed out through the said outlet valve.

In case any obstruction has lodged on the seat of inlet valve 6 the same can be removed as follows. The inlet a is closed and the blow off cock 9 is opened. Then the valve 6 being held by said obstruction from its seat steam from the float chamber -will blow through the valve passage and clean out the same or dislodge the obstruction. In case a heavier float is used a counterweight as shown at h Fig. 2 can be applied. If valve 6 should be blocked or stopped for any reason then by opening direct feed i water will flow from the main a through direct feed valve i to the boiler or float chamber.

The direct feed 71 is formed or bored through a casting or block in which same casting is formed or bored the outlet or passage f and the seat for the valve 6. By applying such one piece casting, all the required feeds or assages with valve seat are likewise applied Such casting is readily applied by bolts or suitable fastening means. The valve e is applied against the valve seat from the interior so that pressure in the boiler will tend to press the valve to close the seat or check waste or outflow through passage a. By having the valve not secured. to but loose from the float c or the lever actuated by the float, the latter can sink orcmove away from the valve and the latter will be still held by the pressure in the boiler to the valve seat in case the inflow pressure from feed a, is'interrupted or weak while the level of water in the boiler is low. As the level of water in the boiler rises and moves the float, the valve, if open, is pressed back to 4 its seat by the lever from the float.

I claim A cleaning feed water regulator for low pressure steam boilers or hot water heating plants and the like, com rising a block adapted to be secured to sue boiler and provided with an inlet valve seat, an inlet valve and a direct feed passage leading into the valve seat and continuing on, under and by said seat, a division wall about which said passage leads, said passage terminating in a downwardly extending portion provided with outlet valve and forming a sediment or mud chamber under the division wall and inlet valve seat so as to enable sediment under the inlet valve seat to be carried past the same and to separate from the feed water before the latter is allowed to pass into the inlet valve seat, said passages being all formed in said block to be attached and detached with the same.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

THOMAS KEENAN.
