JOHN RILEY-KELLEY, OF REELFOOT, TENNESSEE.
BOILER-FEEDING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 61 1,967, dated. October 4, 1898. Application filed February 11, 1898. Serial No. 669,969. (No model) To aZZ whom it may concern:
Be it known that 1, JOHN RILEY KELLEY, a citizen of the United States,residing at Reelfoot, in the county of LakeandState of Tennessee, have invented certain new and use ful Improvements in Boiler-Feeding-Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same.
My present invention relates to an automatic boiler-feeding apparatus.
The object of the invention is to provide simple, durable, and efficient mechanism automatically operated by the variation of the water-level in the boiler to cause the automatic introduction or feed of water to the boiler when the water contained therein falls Referring to the numerals on the drawing,
1 indicates a boiler of any ordinary construc-v tion, from the top or dome of which is led a steam-pipe 2, communicating with a preferably elongated cylindrical float-chamber 3, from the lower end of which is led a waterpipe 4, piercing the shell of the boiler at a point below the lowest level of water in the boiler. By this arrangement it will be seen that the water-level in both the boiler and.
feeding apparatus operated under steampressure. The extremity of the pipe 5, which pierces the upper end of the casing 3, is preferably bifurcated, as shown, in order to permit of the use of balanced valves 6 and 7,
oppositely disposedfiand carried at the opposite ends of-a valve-lever 8, pivoted at its centerto the lower extremity of a pendent bracket 9.- The valve-lever'is in turn connected to what may be termed a valve-stem 10, pivotally connected at its lower extremity to a horizontally-disposed lever 11, pivoted at one end to the side wall of the casing 3 and connected at its outer free end through a link 12 to what may be termed a float-lever l3, pivoted at the opposite side of the casing. The free end of the lever 13, which is located, preferably, axially with respect to the casing 3, is pivotally connected to the float-stem 14, extending upwardly through the top of the casing from a float 15 of any desired construction or dimension and from the opposite end of which depends a guide-stem 16. Suitable guides 17 are preferably provided at proper points to guide the stems 14 and 16 in order to prevent lateral play or vibration of the float 15.
18 indicates a water-gage of any suitable ordinary construction, which may be mounted immediately above the chamber 3 and operatively connected, in a manner not necessary to be described, to the upper end of the stem 14. If desired, a cock-controlled drip-pipe 19 may be led from the bottom of the floatchamber for the purpose of drawing off the water and sediment when it is thought desirable.
The operation of this form of my device will be obvious, since the float, when dropped sufficiently by the recession of the water-level within the float-chamber, will through the intermediate mechanism cause the valves 6 and 7 to open and will permit the steam to pass through the steam-pipe 5 to the pumpinjector or other device. As soon, however, as the level of the water has reached the proper point by the introduction of the feedwater into the boiler the float will actuate the valves to cut oif the steam-supply to the vpipe 5 and the feed will be interrupted until indicator or boiler-feeding device and operated' by the level of the Water within the boiler; but while the present embodiment of my invention appears at this time to be preferable I do not care to limit myself to the structural details set out, but reserve the right to change, modify, or vary them at will within the scope of the protection prayed.
hat I claim is The combination with a boiler, and a cylindrical float-casing in communication with said boiler at its upper and lower ends, of a steam supply pipe having a bifurcated extremity, the branches of which lead into the upper end of said casing, oppositely-disposed balanced valves controlling the passage through the branches of said pipe, a centrally-pivoted Valve-lever connected at its opposite ends to the respective stems of said valves, a float within said casing, a float-stem extending in opposite directions from said float, the upper end of said stem projecting through the head of said casing and operatively connected to suitable indicating mechanism, guides within said casing through which the float-stein passes, a float-lever fulcrumed at one end to the interior of said casing and pivoted at its opposite end to said float-stem, a lever intermediate of the valve and float levers fulcrurned at one end to the casing opposite the float-lever and connected at a point interme diate of its ends to the stem of one of said valves, and a link connecting the free end of said intermediate lever with said floatlever at a pointintermediate the ends of the latter.
In testimony whereof I affix my signature in presence of two witnesses.
