AUTOMATIC FEED-WATER REGULATOR FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 609,544, dated August 23, 1898. Application led December 18, 1897. Serial No. 662,423. (No model.)

To @ZZ wil/m it may concern:

Be it known that I, PRESTON ON EAL l-Irrr, a citizen of theUnited States, residing atWarren, in the county of Bradley and State of Arkansas, have invented certain new and useful Improvements in Automatic Feed-W`ater` Regulators for Steam-Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is a device for keeping a steam-boiler automatically supplied with water; and it consists of a steam ball-float valve having an arresting-arm in combination with a steam-pump and is described as follows:

Figure lis a longitudinal sectional view of a steam-boiler, showing an end view of my ballfloat valve and arresting-arm in position. Fig. 2 is an end view of a steam-boiler with the head cut away, showing the boiler in perspective and in position, also showing an end view of the steam-pump and its connections with the valve and boiler. Fig. 3 is a longitudinal sectional view of my valve, and an arrestingarm, with the lever and handle of the valve removed. Fig. 4 is a transverse sectional view of the valve on the line ce 0J, Fig. 3.

. 1 is the steam-boiler.

2 is the dome.

3 is the valve.

4 is the lever.

5 is the balliioat.

6 is the pipe leading from the valve 3 to the pipe 7.

7 is a pipe leading from pipe 6, conveying steam from valve 3 through pipe G into cylinder 8 of the steam-pump 9.

10 is a pipe which conveys the water from the water-reservoir 1l into the boiler 1.

The valve 3 consists of ahollow cylinder 12, provided with a steam-inlet 13 and with packing- heads 15 and 16. 12 is a shaft 17, having at its middle portion an enlargement 18. This shaft is hollow from point 19 to its left-hand end 14. Said enlargement 18 has an opening 20, concentric with and corresponding to opening 13, said opening opening onto the hollow part of shaft 17. On the end 21 of shaft 17 is rigidly secured a lever 4, and on the free end of said lever is secured a hollow ball-float 5.

The dotted line 22 represents the low-water mark in the boiler, and dotted line 23 rep- Fitting in this cylinder resents higlrwater mark, and the valve 3 is so set that when the Wateriin the boiler is so exhausted as to be down to the low-water mark the openings 13 2O are opened and the steam passes through said openings and opening 14, thence through pipes 6 and 7 into cylinder 8, and operates the steam-pump 9 and forces the water from reservoir 1l through pipe 10 into the boiler below low-water mark. When the water rises to high-water mark, the opening 13 is closed by the turning of the shaft 17, preventing the further escape of steam, and the pump remains idle until the water becomes sufciently low in the boiler to open the passages 13 2O 14 for the steam to again enter the pump.

24 is an arresting-arm secured to the packing-head and situated to arrest the downward movement of the lever 4 and prevent it from falling low enough to cut off the steam from the openings 13 2O should the water get lower than the low-water mark 22.

Thus it will be seen that with my device a steam-boiler may be fed automatically and kept at all times with a sufiicient amount of Water in the boiler.

Having described my.. invention, whati I claim as new, and desire to secure by Letters Patent, is

The combination of the steam-boilerl; the valve 3, secured on the inside of said boiler and consisting of the hollow cylinder 12, provided with a steam-inlet 13,',and packingheads 15 16; shaft 17, provided with an enlargement, 13, and working on the inside of cylinder 12, said shaft being hollow from point 19 toits end 14, and having an opening 20, corresponding to opening 13 passing into the hollow of said shaft 17 5 lever 4, rigidly secured to said shaft 17 and its end 21; hollow ball 5, secured on the free end of lever 4; arresting-arm 24 secured to packing-head 15; pipe 6, one end secured to the end 14 of valve 3, and passing thence through boiler l, and adapted to convey steam to a steam-pump, 9, substantially as shown and described and for the purposes set forth;

In testimony whereof I aflix my signature in presence of two witnesses.

PRESTON ONEAL IIIPP.
