Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed June 20, 906. Serial No, 322.575.

To all 'IIJ7'L0'I'7'L it may concern:

Be it known that I, THOMAS citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful KEENAN, a I float 3 sinks, and the lever Improvements in Feed-l/Vater Regulators, of f which the following is a specification.

This invention relates to means by which the water-supply for a boiler can be auto matically kept at required level.

This invention is set forth in the following specification and claims, and illustrated in the annexed drawings, in which.

Figure 1 is asectional view of a device embodying this invention. 2 is a detail view.

In the drawings is shown a reservoir a, which can be supplied, as well as discharged, by conduit Z). The supply from conduit 0 is prevented from flowing back by check-valve (Z, and the discharge 6 has a check-valve, as shown atf. A pressure-inlet tube 9 communicates with the steam or pressure space of either the boiler h or of a space communicating with the boiler. I11 the drawings is shown the table or hollow platei of a dryingpress; but the invention is not limited to such use. The reservoir a has a lever is fillcrumed at m. To this lever is pivoted a stem 0 with two nuts or bumper-points p. A float 9 slides on the stem to bump against one or another of the points 7). A counterweight at one arm of lever ittends to balance the other arm or the stem 0, and easy operation is attained.

hen the water in reservoir a is below a certain level, the float 9 coming against the lower bumper-point p actuates the lever it to open the escape-valve s and close the pressure or steam entrance valve t at pressureinlet 9. The valve at s when open allow pressure in the reservoir to escape, and the water-pressure from the main through intake 0 will fill the reservoir a. As the float rises to the upper contact-point p the lever 7c is moved to close valve 8 and open valve t.

The pressure from valve If in reservoir a will cause the reservoir to discharge through conduit e into the'chamber 2. In this chamber is a float 3. This float or its stem is pivoted to a lever 4, fulcrumed at 5 and having a counterweight 6. This lever 4 actuates a valve or plug 7, sitting against inlet e.

' allow the when the water in chamber 2 is low, the

4 moves valveplug 7 away from the mouth of inlet 0 to fluid to enter or the chamber 2 to be charge: As the float is carried up by the rising fluid the valve 7 is closed and the flow from inlet a stopped. The chamber 2 communicates with the boiler h. As the water in the boiler is consumed the level in the boiler, as also in the chamber 2, sinks, and the descending float 3 opens the inlet 6. A feed thus occurs which is continued until the water in the boiler has returned to the desired level. The float 3 then again cuts off the supply until the water sinks below the required level.

The pressui'e conduit 9 can be closed by a valve 9, if required. The device, as seen, is automatic. As the water sinks in the reservoir a the pressure-valve .9 opens for the main supply from c to fill the reservoir. As the water sinks in the boiler or in the floatchamber 2 the valve 7 is opened to allow refilling. Sight-glasses can be applied. The valve 7, being at the mouth of the entrance 6, will break the force of the inflow or charge so as not to agitate the level visible through the sight-glass 10. A blowofl' cock can be applied, as seen at 11. In case valve 9 is closed and valve 12 at reservoir a is opened then the air in reservoir a can escape at valve 12 as water feeds in, from supply 0. The boiler h and floatcha1nber 2 have a common waterlevel therein. The steam or pressure from the boiler rising into the space i can communicate thence with the reservoir a by way of pressure-inlet tube 9.

I claim 1. The combination with a reservoir and waterinlet, of a pressure-inlet extended through the water-inlet and having a valve, a float-actuated valve in the reservoir, a feedwater tube communicating with the reservoir, and a float-actuated valve in the feed-water tube.

2. The combination with a boiler, of a float-chamber and inlet, a float in the chamber, a counterbalz'niced lever connected to the float and having a valve for the inlet, a reservoirhaving a pressure-outlet, a pressureinlet tube extended from the pressure or steam space of the boiler into the reservoir, a discharge-pipe from the reservoir made to ICC communicate with the inlet, valves for the pressure-out1et and pressureinlet, and a floatactuated lever for opening and closing the valves in the reservoir.

3. The combination with a boiler and a float-chamber having a common Water-level,

I inlet, valves for the pressure-outlet and pressure-inlet, and a fl0at-actuated lever for opening and closing the valves in the reser- I5 voir.

In testimony whereof I have hereunto set my hand in the presence of two subscribing inlet-valve for the chamber, a float'and lever Witnesses.

for actuatin the valve a reservoir having a pressure-outlet, a pressure-inlet tube eXtend- THOMAS KEENAN' ed from the pressure or steam space of the Witnesses:
