SAMUEL S. FLEMING, OF SARVERSVILLE, PENNSYLVANIA.
FEED-WATER MECHANISM FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 468,014, dated February 2, 1892.
Application filed May 22, 1891. Serial No. 393,747. (No model.)
To aZZ whom it may concern..-
Be it known that I, SAMUEL S. FLEMING, a citizen of the United States, residing at Sarversville, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Feed-\Vater Mechanism 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 intended as an improvement on my prior patent, No. 445,760, dated February 3,1891, the object of my present invention being to provide a more perfect and an automatic arrangement for feeding the wa ter to the boilers.
\Vith this end in view my invention consists in the peculiar features and combinations of parts more fully described hereinafter, and pointed out in the claims.
In the accompanying drawings, Figure 1 represents a perspective view of my complete invention; Fig. 2, arear end view; Figs. 3 and at, views of details.
Referring to the drawings, the referenceletter a denotes a pair of twin boilers provided with fines and adapted to be placed upon any suitable setting. A pair of twin water-tanks l) b, cylindrical in shape and extending longitudinally with the boilers, are placed over the latter and a drysteam drum 0 is interposed between these tanks with its lower circumference resting upon the boilers, as more clearly seen in Fig. 2. This dry-steam drum is thus placed, in order that the steam may be better reheated as it passes out to the engine, and also to give compactness to the whole structure. A vertical steam-receiving dome (Z is mounted uponthe top of the forward portion of the dry-steam drum 0 and receives the steam directly from the boilers through pipes c c. Any condensed steam will be carried off through lateral pipes (1, leading down to the tanks Z) I), while the live steam passes on down through pipe 6, leading into the front end of dry-steam drum 0. The water-tanks I) Z) and dry-steam drum 0 are shortened at the rear ends to accommodate an auxiliary water cylinder or tank f, placed transversely over the rear ends of the boilers. The supply of water enters the top of this tank f through valved pipe 7L and branch pipes h to the water-tanks b l), thence through these tanks into the boilers through branch pipes 7t". It is then generated into steam,
which rises into dome (Z, thence passes down through pipe e and out through dry-steam chamber 0 and up through pipe 1' to the engine.
The general structure just described, being shown and fully set forth in my prior patent before mentioned, will not require further description.
I will now proceed to describe the automatic feed-water mechanism used in connection therewith and which forms the principle subject-matter of the present specification. This mechanism consists of a horizontal driven shaft 75, provided with alternating eccentric cams 7t driven by a beveled gear 7;". These eccentric cams reciprocate a pair of second-class levers Z, fulcrumed on standards Z and connected with vertical rods Z", which.
rods are in turn attached to valves m m in horizontal water-supply pipe 9 and also the valvej in pipe h, Fig. 3. The auxiliary watertank f is provided with a dome f, which contains a float f and it is also provided with a water-gage o to indicate the height of the water within. The float actuates a governorvalve m" through the medium of a bell-crank lever o, fulerumed in the side of the tank, and a vertical rod 0. The latteris provided with a turn-buckle o for adjusting its length, and hence regulating the amount of cut-off to the valve and the supply of water to the tank. The dry-steam cylinder is conn'ected with the pipe and tank f through short vertical pipe g. The flow of water from the auxiliary tank f through pipes h is regulated by a valve j in short pipe 71 Fig. 3, which valve is operated by the rod Z", connected to lever Z, whereby both the valves m and j are opened simultaneously, the latter to draw cit the water and the former to admit steam into the tank to overcome or balance the back'pressure from the boiler.
The preferred construction of my machine having thus been set forth, I will now proceed to describe its operation. \Vater is supplied to auxiliary tank f through pipes g and g. \Vhen the tank becomes full, the float rises, lifts the bell-crank lever, and cuts off or lessens the supply by closing the governorvalve m". The cam-shaft k is made to continuously revolve through the medium of bevel-gear 7c", and in so doing intermittently opens and closes the valves m m j. If governor-valve m is closed, no water will be admitted to the tank by such intermittent opening and closing; but when it is open the water enters the pipe 9 between valves m and m and is emptied from the pipe as soon as the eccentric cam Zc lifts the lever Z and opens valves m and j, Figs. 1 and 8. At each admission of water to the tank f the eccentric cam 70 allows the lever Z to descend and close Valve m, so that the dry steam from chamber a forces the water down into the tank f. Simultaneous with the admission of water to the upper part of the tank it is drawn off below and passes on to the tanks 1) Z), from which it passes to the boiler and pursues the course hereinbefore outlined. Any-excess of steam escapes at the safety-valve g.
It is evident that my invention could be varied in many slight ways that might suggest themselves to a skilled mechanic. Therefore I do not limit myself to the exact construction herein shown, but consider myself entitled to all such Variations as come within the spirit and scope of my device.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 4 1. In an automatic feed-water device for steam-boilers, the combination of an auxiliary tank provided with a float, a water-supply pipe provided with a valve actuated by said float, a driven shaft carrying alternating eccentric cams, a pair of levers operated by said cams, valves located in said water-supply pipe and actuated by saidlevers, and a valved outlet-pipe leading from the bottom of the auxiliary tank, all arranged and adapted to operate in the manner and for the purpose substantially as described.
2. In an automatic feed-water device for steam-boilers,'the combination of a pair of boilers, a pair of tanks, a steam-drum, dome, and connectingepipes, substantially as described, an auxiliary tank, a water-supply pipe communicating with the top of said drum and tank, an outlet-pipe leading from the auxiliary tank to said pair of tanks, a float located within the auxiliary tank, a governorvalve actuated by said float, and a pair of alternating levers connected to operate valves commanding the pipes. leading to and from said auxiliary tank, in the. manner and for the purpose substantially as described.
In testimony whereof I affix m y signature in presence of two witnesses.
SAMUEL S. FLEMING.
