SPECIFICATION forming part of Letters Pateilt N0. 549,570, dated November 12, 1895.
Ap lication fi1 dhpril8,l89 5. Serial to. 545,025; (Nomodeh) To all whom, it may concern.-
' Be it known that I, THOMAS H. JONES, a citizen of the United States, residing at Chicago, in-the county of Cook and State of llli nois,have in vented certain new and useful Improvements in Apparatus for Preventing Boiler-lncrustation andl do hereby declare the following to be a full, clear, and exactde scription of the invention, such as will enable others skilled in the art to which it appertains' to make and use the same.
' This invention relates to an improved apparatus for preventing incrustation in steamboilers, and has particular reference to the use of metallic mercury therefor.
It has been found from practical experiments that mercury slowly volatili'zes under hot-water pressure at the common temperatures-of feed-water for steam-boilers, and that the exhalations therefrom prevent the carbonates or other impurities in the waterfrom adhering to or incrusting the parts of the boiler. v
The object of the invention is to provide a suitable apparatus adapted to be connected to the feedwater pipe between the heater and boiler, by which the process of volatilization' maybe conveniently carried out in a simple and efficient manner.
The invention consists in the novel features of construction and combination of parts hereinafter described and set forth, reference being had to the accompanying drawings, in which--= I 1 Figure 1 is a central longitudinal section of my improved apparatus, taken on the line 1 1 of Fig. 2. Fig. 2 is an end elevation of the same. Fig. 3 is a'transverse section on the line 3 3 of Fig. 1; and Fig. 4 is a section taken on.the line fl f Figs. 1 and 3, showingaplan view of theperforated cover-plate.
Referring to the drawings, 1 designates a hollow cylindrical casting adapted to' form a connection and continuous passage between the feed-water pipes 2 2 ,into which the ends of said pipes are adapted to be screwedto forma tight joint therewith. Saidhollow cast mg is provided with a chamber 3, projecting from one side thereof and cast integral there with. Said chamber is adapted to form a vessel or reservoir for holding the mercury 4,

.my invention.
fcurial vapors. i
plate?) is fitted to rest upon shoulder 6,formed at the sides and ends of said chamber. Said cover-plate is adapted to'be inserted within said hollow casting through the feed-pipe opening 7 in the end'thereof. 'Said opening,
is'made of sufficient diameter for this purpose, and is closed up by means of a scgew-l a1 feed-pipe ends do not terminate at the inside of the hollow casting ends, but are extended some distance toward its center and brought nearer together to reduce the turbulence or agitation of the water therein. 9 is ascrewplug fitted to an opening through the top of said hollow casting, and a central opening or perforation 10 is formed through the coverplate in the line with said plug-opening for the'purpose of replenishing and refilling the mercury-chamber. A pet-cock ll'is provided at the top for the removal of air from within the hollow-casting, and the feed-water pipe is connectedwith the feeding apparatus, heater, and boiler, and'provided withthe usual appliances of cocks and valves therefor.
The apparatus is adapted in size to thecapacity of the boiler for whichit is designed.
In practice it is found (starting with aclean boiler) that for a period of six months three pounds of mercury per hundred horse-power will give the" desired resuht. The boiler should have the customary periodical wash-- out, at which inspection should 'be made "to ascertain the quantity of mercury remam'ng in the apparatus, for which purpose a s all spoon adjustable upon a wire rodis provided,
adapted to be inserted through the central openings, by which thedepths of mercury is measured.
- 1 unaware that metallic mercury, combined with other materials, has heretofore been used for internally coating the surfaces of steam-boilers to prevent rust and incrustation therein, and I make" no claim to such as In my invention no union or amalgamation to form a coatingis designed v or efiected, the, scale-formationbeing pre-. vented solely by the continuous impregnation of the feed-water with the exhaledmen It is obyious that my invention should not be restrictedto the use of I metallic or free mercury, as various compounds of other ma- IOO terial could be used as a vehicle for the mercury, and,'in fact, any combination of material for the purpose capable of being slowly volatilized or evaporated might be made use of without departing from the spirit of my invention.
Having described my invention, I claim- 1. The herein described apparatus for preventing scale formation in steam boilers comprising", in combination with the feed water pipe, a hollow casting connecting with said feed pipe, a chamber or reservoir formed integral with said casting, adapted to contain mercury or other evaporative substances, and a cover plate for said reservoir provided with perforations through which the feed Wateris brought in contact with the mercury in said reservoir, substantially as and for the purpose deseribed.
2. The combination with the feed water pipe of a steam boiler, of an apparatus for impregnating the feed water with the vaporized exhalation of mercury or other slowly evaporative material substances, adapted to prevent inerustation in steam boilers, consisting of a hollow casting 1, connected with said feed water pipe, a chamber or reservoir 3, cast integral with said hollow casting, a perforated cover plate 5 for said chamber or reservoir, and an opening 7 in the end of said 30 THOMAS H. JONES. TWitnesses:
