feed of such com ound to the boiler.
For a full un ersta'nding of the construction, merits, and advantages of my invention reference is to be had to the following description and to the. accompanying drawmg,-
which illustrates the feedin apparatus by a view in longitudinal vertica section.
Making renewed reference to the drawin 1 designates a' boiler feed-pipe, which lea s from a pump or irfector andconnects at the end '2 with a bo' er. (Not shown.) This pipe is preferably made in sections by interposing suitable couplings 3 and 4 between the ends of several ipe-sections, although these couplings maylbe dispensed with and the pipe 1 tapped in several places.
5 designates a tank or reservoir into which the liquid boiler compound is introduced, as by removing the screw-plug 6 at the top. From the lower end of this tank extends an intake-pipe 7, in which is a suitable stopcock 8. The end of the pipe is threaded and screwed within the coupling 3, although it may be screwed directly within the pipe 1. Its lower end 9 projects a considerable distance within the feed-pipe and is preferably cut at anangle, so as to provide a take-up for some of the water assing through the feed-pipe, as indicated y the arrowsin the drawing.
From near the top of the "reservoir 5; ex-
tends an escape-pipe 10. This pi e hasa suitable valve 11, and its lower en j is fitted into the coupling 4 and projects in'tothe feedpipe 1, being preferably cut so as to deliver the boiler-compound into the f -pi e, but not take up an of the water passing t ough the ipe, as in icated by the arrows.
en the reservoir 5 has been filled with a suitable liquid boiler com ound, some of he water passing through t e feed-pipe 1 will enter the reservoir 5 through the intake-pipe 7, the opening of which faces in a direction opposite to the flow of-the water through the feed-pipe to receive the im act of the water therein, causing some of t e water flowing through the feed-pipe to enter the said intake'pipe 7 and force the compound in the reservoir 5 out through the escape-pipe 10 and down to the feed-pipe again, where it is carried forward by the force of the "water intake-pipe, the openin of the esca e-pipe 10 being turned in the irection of t e flow of the water, so as not to receive the impact thereof. Thus it will be seen that there 1s an in'ection action at the take-up end of the inta e-pipe and an ejection action at the delivery end of the escape-pipe 10. A valve 8 may regulatethe flow of Water into the reservoir, and the valve 11 may regulate the discharge of the compound from the reservoir,- while the water in the reservoir may be drawn olf throu h the petcock 12.
Having thus escribed my invention, what I claim, and desire to secure by Letters'Patcut, is
In an apparatus of the class described, the combination with the boiler feed-pipe, and the reservoir, of means for forcin a boiler compound from the reservoir by t e flow of water through the feed-pipe, com rising an intake-pipe communicating with t e bottom of the reservoir and with the feed-pipe and having its end that enters the feed-plpe out obliquely with its opening facing in a direction opposite to the. flow of the water, where- BLAIR A.
