THOMAS G. RAKESTRAW, OF DETROIT, MICHIGAN.
FEED-WATER REGULATOR.
Specification of Letters Patent.
Patented July 30, 1907.
Application filed June 5, 1906. Serial No. 320.229.
To all whom it may concern.-
Be it known that I, THOMAS G. RAKESTRAW, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Water-Feed Regula tors; and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in water food regulators for steam boilers, shown in the accompanying drawing and more particularly set forth in the following specification and claims.
The drawing shows the water column of a steam boiler with my improvement connected therewith, by means of which, the valve governing the steam supply to the pump or water to the boiler is controlled.
The object of my invention is to provide an appa ratus which will automatically govern the opening and closing of the valve controlling the delivery of Water to the boiler or the passage of steam through the pipes to operate the feed pump. The construction of this apparatus is such that its action is not dependent upon the expansion or contraction of metal tubes, rods or other devices, but is positive and sure in its action under all conditions of temperatures.
Referring to the letters of reference shown on the drawing, A represents the water column of a steam boiler provided with the usual gage-cocks and gageglass A.
B is an auxiliary water column connected at top and bottom by nipples b 011 a line with the upper and middle gages oi the water column.
C is a ball float having a rod 0 rising from its top, its upper end connected with a short lever D pivoted at (l in a-yoke depending from the shell of the valve E. The stem E of the valve E being engaged to the lever D, the rising and lowering of the float G will control the opening and closing of said valve.
F is a pipe leading irom the valve E connecting the auxiliary water column D with the cylinder G.
G is a piston housed within the cylinder G, its rod 9 connected to the lever h' controlling the shut-off valve H governing the delivery of water to the boiler, or steam to the pump, as the case may be.
G and G are pipes leading from the exhaust ports.
G are valves for reducing the exhaust opening.
I is a bell crank lever pivoted in a yoke projecting from the shell of the valve J, one arm of said bell crank lever engaging the stem of the valve J, the other pivoted to the rod 0 of the float G.
K is a pipe leading from the auxiliary water column to the inlet port of the cylinder G, the delivery of steam to the cylinder being under the control of the valve J.
B is a suitable draw-off valve in the bottom of the auxiliary Water column B.
The operation of my invention will be readily understood. When the water in the boiler drops below its predetermined level, as indicated in the drawing, the float O in lowering will close the valve J and open the valve E, thereby admitting steam through the pipe F into the cylinder G, forcing the piston G to the end of its stroke, thereby opening the valve H admitting water to the boiler, or steam to the feed pump, as the case may be. When the water in the boiler again assumes its predetermined level, the float G in rising will force the valve E through its connection therewith to its seat, at the same time opening the valve J, by means of its connection with the bell-crank lever I. This action admits steam through the pipe K to the cylinder G at its opposite end, thus forcing the piston G to return to the position indicated in the drawings, and thereby closing the valve H against further admis sion of water to the boiler, or steam to the feed pump.
It will be evident that the form of the valves E and J may be varied from that shown in the drawing and the valves arranged to seat outside of the auxiliary water column without departing from the spirit of this invention.
Having thus described my invention, what I claim In a feed water regulator for steam boilers, a water column having connections with the boiler, a steam cylinder having connections with the column, a valve arranged to operate with each of the latter connections, a feed pipe communicating with the boiler, a shut-elf valve in the line of the feed pipe, a piston arranged within the cylinder and having connection with said shut-oll valve, a float valve disposed in said column and operatively connected with the valve of the second mentioned connections, and a continuously open exhaust from both ends of said cylinder.
In testimony whereof, I sign this specification in the presence of two witnesses.
