CHESTER P. HALL," OF CHICAGO, ILLINOIS.
APPARATUS FOR FEEDING SCALE-PBEVENTlVl-i COMPOUNDS T0- BOILEIiSr SPECIFICATION forming part of Letters PatentNo. 49,479, dated November 5, 1895.
Application filed March 14, 1895. Serial No. 541,796. (No model.)
To all whom it may concern:
Beit known that I, CHESTER P. HALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Apparatus for Feeding Scale-Preventive Compounds to Boilers; and I do hereby declare the following to be a full, clear, and exactrdescription of the same, ref: erence being had to the accompanying drawing, forming a part of this specification.
This invention relates to an apparatus in which the scale-preventive compound is fed to the boilerat a point, between the boiler and feed-pump, so that the packing, &c., of such pump will not be exposed to the corrosive and injurious action of such compound;
and the object of the present invention is to provide a simple and eflicient form of apparatus by which such "gradual, uniform, and continuous feed of the scale-preventive is effected, and which, in addition, embodies the featuresof a ready and convenient recharging of the apparatus and avisible feed of thetcompound in its passage from the apparatus into the feed-water pipe of the boiler. I attain suchobjects by an apparatus of the construction'and arrangement of parts substantially as illustrated in the accompanying drawing, which represents a-view, thereof in sectional elevation.
In the feeding of scale-preventive compounds to steam-boilers as heretofore practiced it hasbee'n customary to feed the com pound in comparatively large quantities and atlong intervals into the boilers or to mix the same with the feed-Water before it has passed through the feed-pump.
\Vith the present invention the scale-preventive compound is fed in a gradual, uni
form and constant manner in the form of drops to the feed-water after it leaves the feed-pump and before it enters the boilers, so as to be thoroughly and uniformly mixed with such feed-water during thepas'sagq of the same to the boiler; and the present invention admits of the feeding of 'any desired quantity of the scale-preventive compound in a continuous manner and in a proportionate relation to the amount of feed water passing into the boiler.
In the carrying out of my present improved method I make use of an apparatus such as shown in the accompanying drawing, refering to which- 1 1 represents a single-acting cylinder for the "scale-preventive compoundhaving a piston 2.
3 is a double-acting operating cylinder of a comparatively larger area thanthe, cylinder 1 and provided rod 5. t
with a piston 4, connected I rigidly to the piston 2 by a connecting piston- 6 is'a'reversingwalve of a usual and well known form and having port or pipe communications 7 and 8 with the respective ends of the cylinder 3, a supply-pipe connection 9 p with the feed-water pipe 10,that extends fronr the feed-pump to the boiler, and a waste-pipe connection 11 through which the waste or exhaust takes place in'the operation of the cylinder 3. ,The valve 6 will be provided with an operating-handle .12 for convenient operation charge. a
13 is the storage tank or reservoir for the scale-preventive compound connected, .to the top portion of the cylinder .1 by a pipe-connect-ion 14, in which is inserted a check-valve 15 to prevent a backflow of the compound from the cylinder 1 to the tank 13 in the op- I eration of the. apparatus.
by the engineer or other person in 16 is a pet or air cock in the top portion of the cylinder 1 to admit of the escape of airder 1 by a connection 19 andat bottom with.
the feed-water pipe 10 by'a connection'20.'
This visible feed attachment is intended to contain a body of oil inthe'vertical passage 17, down through which the scale-preventiye com pound'descends by gravity in its passage to the feed-water pipelO. 21Jis a regulating-valve at the top of th compound fromtthe cylinder 1( The operation of my improved apparatus is as follows: In filling the apparatus the reversing-valve 6 is shifted so as to bring pressure through pipe or port 7 upon the upper side of the piston 4. The pistons-2 and 4 are thus caused to descend to their lower positions. The scale-preventive compound is thus drawn as well as forced by gravity into 7 and exhaust-pipe 11, which are now in communication. The pressure on the under side of the piston 4 causes the same to gradually ascend, forcing the piston 2 upward in unison and displacing the compound above the piston 2 out of the cylinder-1, through the visible feed 17, into the feed-Water pipe 10 in a gradual and uniform manner.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent isi 1.
