SPECIFICATION forming part of Letters Patent No. 758,909, dated May 3, 1904. Application filed October 12,1903. Serial No. 176,597. No model.)
T 0 (1 7 l IUILO'III/ it TI'MLU concern:
Be it known that I, FREDERICK A. GALE, a citizen of the United States, and a resident of Chicago, in the county of Cook, State of lllinois, have invented certain new and useful Improvements in \Vater-Heating Apparatus, of whichthe following is a full, clear, and exact description.
This invention has for its object to provide an improved construction of water-heater which while suitable for the heating of waterfor many other uses is more especially designed for the heating of water to be used in the washing or charging of steam-boilers.
The invention consists in the features of improvement hereinafter described, illustrated in the accompanyingdrawings, and more particularly pointed out in the claims at the end of this specification.
Figure 1 is a view in side elevation of an apparatus embodying my invention. Fig. 2 is a view in vertical section.
The water-heating chamber A consists,pref erabl y, of a casing titted upon its interior, with tubes leading from end to end of diaphragms u and a, that extend across the casing A adjacent its ends. The construction of the heater is very similar to that of an ordinary tubular boiler and need not be more particularly described, it being understood, of course, that the water to be heated will circulate about the tubes and between the diaphragms a and a. The water to be heated will be delivered to the chamber A by a supply-pipe B, and this pipe B preferably leads from a forcepump 0 of usual or suitable construction. The water within the casing-A is to be heated by steam (preferably exhaust-steam) from a suitable source of supply, this steam being delivered to the end of the heating-chamber A by a branch (l of the main steam-pipe D. At the opposite end of the heating-chamber is connected a pipe E, by which the water of condensation will be withdrawn from the heatingchamber, and this pipeE is connected to a suction-pump F of usual or suitable construction. Live steam will be admitted by a pipe Gr to the valve-chamber c of the pump C, whence it will pass in the usual manner to the steamcylinder 0, and similarly live steam will be delivered by a pipe R to the valve-chambenf' of the pump F, whence it will pass to the steam-cylinderf" of said pump. The waterheating chamber A will be provided with a water-discharge pipe K. by which heated water will be withdrawn from time to time, as required for use, and preferably the chamber A will be provided also withasafcty-valveA.
From the construction of parts as thus far defined it will be seen that steam passing through the steam-pipe D will not enter the tubes of the water-heating chamber A in any considerable quantity except during the time that hot water is being withdrawn from the chamber and cold water is being admitted thereto, at which time the pump F will operate to withdraw water of condensation from the adjacent end of the water-heating chamber. So, also, it will be seen that so long as the pump C is out of action no water will be delivered to the water heating chamber. hen, however, the pump is in operation, water will be forced into the water-heating chamber A and around the tubes of said chamber, and at such time water of condensation will be withdrawn from the chamber by the pipe F. Hence it will be seen that steam from the pipe l) will be used only at such times and in such quantity as may be required to effect the heating of the water within the chamber A.
In order to render automatic the delivery to the chamber A of the water and the withdrawal from the chamber of the water of condensation, 1 provide governor mechanism that serves to bring the pumps C and F into operation when water is withdrawn from the heating-chamber A and fresh water and steam are to be admitted thereto and which serves to throw these pumps out of action when the plenum or predetermined pressure of water exists in the water-heating chamber. The governor mechanism M (shown in the accompanyingdrawings) is what is commonly known as the Fisher steam-pump governor, although it will be understood that other suitable typcs of governors might be employed without departing from the spirit of this invention. casing m, the induction-port 2 of which is This governor M comprises a valveconnected with a live-steam-supply pipe G, and the delivery-port 3 of which casing is connected with the pipe G, whereby live steam is admitted to the valve-chamber of the pump C. As shown, the casing of the gov ernor M is formed with an interior extension having duplicate valve-seats m and m ,whereon rest the valves m and m that are connected together. The stem m of the governor-valves passes upwardly through a suitable stuffing-box and into a chamber M, wherein is held a coiled spring M The bottom of this spring M bears against the subjacent part on the casing, while the upper end of this spring bears against the piston m", that is secured to the upper end of the stem 1n. The top of the casingM is formed with a port 722 from which leads a pipe N, that is connected by a branch pipe N with a casing C in communication with the discharge side of the water-cylinder of the pump C. In like manner a similar governor M is connected to a pipe R for the admission of live steam and with a pipe whereby live steam is delivered to the valve-chamber of the pump F. The upper end of the governor M is connected with the pipe N.
From the foregoing description it will be seen that the pistons at the top of each of the governors M and M will be subjected at their upper sides to the pressure of water within the discharge side of the pump (1, which pressure will correspond, of course, with the pressure within the water-heating chamber A, and the tension of the coil-springs of the governors M and M will be so adjusted that when the pressure of water Within the chamber A is reduced by the withdrawal of water from the chamber A the coil-springs of the governors M and M will lift the valves m and m of each of the governors from their seats and will admit live steam to the valve-chambers of the pumps 0 and F, thereby bringing these pumps into operation. When the pumps C and F are thus brought into operation, fresh water will be delivered by the pump G into the chamber A, and water of condensation and exhaust-steam will be Withdrawn from the chamber A by the suction-pump F. As soon,
thereby throwing these pumps out of action.
It is manifest that the precise details of construction above set out may be varied by the skilled mechanic without departure from the spirit of the invention.
So far as I am aware this invention presents the first instance of a water-heating apparatus in which the supply of water and steam to the heating-chamber is automatically controlled by the withdrawal of water from said chamber.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A water-heating apparatus comprising a water-heating chamber provided with a pipe for delivering cold Water thereto and with a pipe for withdrawal of heated water therefrom, a pipe for admitting steam to said waterheating chamber, a pipe for withdrawal of water of condensation from said chamber, and governor mechanism for automatically and simultaneously causing the admission of fresh water to the heating-chamber and the withdrawal of water of condensation therefrom.
2. A water-heating apparatus comprising a water-heating chamber, a pump for delivering cold water thereto, a pipe for the discharge of hot water therefrom, a pipe for admitting steam to said water-heater, 'a pump for causing the passage of steam through and withdrawing the water of condensation from said water-heating chamber and automatic governor mechanism for controlling the passage of live steam to said pumps and a pipe whereby said automatic governor mechanism is subjected to the pressure of the water within the heating-chamber. c
