JULIO H. RAE, OF MILFORD, DELAIVARE.
BOlLER-FEED.
SPECIFICATION forming part of Letters Patent No'. 404,730, dated June 4, 1889.
Application filed February 28,1889. Serial No. 301,503. (No model.)
To all wil/077@ t may concern:
Be it known that I, JULIO H. RAE, a citizen ot" the United States, residing' at Milford, in the State of Delaware, have invented new and useful Improvements in Boiler-Feed, &c., of which the following' is a specification.
This invention relates to an apparatus by means of. which the exhaust-steam of au engine can be returned into the boiler to which the engine is connected, so that the heat of the exhaust-steam is not wasted.
The peculiar construction of my apparatus is pointed out in the following' specilication and claim, and illustrated in the accompanying' drawing, which represents a longitudinal vertical section.
In the drawing', the letterA is a tank of sufficient strength to withstand the pressure to which it may be exposed. This tank connects by a pipe B with the exhaust-port of a steam-engine, and by a pipe C with the steamboiler D, from which the steam-engine derives its live steam. This feed-pipe C connects with the barrel of a pump E, the plunger of which may be operated from the steamengine or from any suitable source of power. In the inner end of the pu mp-barrel is a checkvalve a., and the feed-pipe C is provided with two check-valves b b.
F is a spray-pipe, which connects with a pump G, that serves to draw water from a well and force it into said spray-pipe and through a rose c, secured to the end of this pipe. This rose is situated in a chamber (l, Jformed in the -feed-pipe O.
Then the apparatus is in operation, the
exhaust-steam accumulated in the tank A is drawn into the pump E and driven therefrom through the feed-pipe C, and as it passes the spray-chamber d it is condensed and then forced into the boiler D.
It will be readily seen that by this apparatus all the heat (or nearly so) of the exhauststeam is utilized, and the great waste of heat which takes place when the exhaust-steam is permitted to escape into the open air is avoided. At the same time the pump E can be made of such a capacity that during the operation of the apparatus the pressure in the tank A never rises-much, if anything, above the atmospheric pressure, so that the exhaust from the steam-cylinder is not obstructed.
Vhat I claim as new, and desire to secure by Letters Patent, is-
The combination, with a steam-boiler and a tank for the reception of exhaust-steam from an engine, of a pump communicating with said tank, a valved feed-pipe leading from said pump to the boiler, and a-water-spraying pipe discharging into the feed-pipe between the tank and the boiler, whereby'the exhauststeam is drawn from the tank, forced into the feed-pipe, condensed therein, and forced into the boiler, substantially as described.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
