WATER-HEATER.

srnorFIoA'rroN forming part of Letters Patent No. 517,572, date April 1894- Application filed January 18. 1892. Serial No. 418,432. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD HAYES, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Water-Heaters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in heating apparatus particularly applicable for use with the portable boilers of fire engines and like devices, and hasfor its object the production of a simple and effective construction which is readily connected to the portable boiler for causing a constant circulation of hot water to flow therethrough and is read-' ily detached therefrom for permitting the hasty removal of the portable boiler; and to this end it consists, essentially, in a heating system, a watery circulating system, the water of which is. heated by the former system, a pair of fixed pipes connected to the Watercirculating system and having their extremities adapted to be connected to the inlet and outlet pipes of the portable boiler, and movable rods in the fixed pipes for opening check valves upon the inlet and outlet pipes of theportable boiler. j

The invention furthermore consists in the detail construction and arrangement of the parts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention,reference is had to the accompanying drawings, forming a part of this specification, in which, like letters indicate corresponding parts in all the views.

Figure 1 represents an elevation, partly in section, of my improved invention shown as supported on sections of a pair of floors and as operatively connected to the portable boiler of a fire engine. Fig. 2 is a longitudinal vertical sectional view of my improved heating apparatus. 7 Fig. 3 is an enlarged longitudinal vertical sectional View of one of the pipes projecting from the portable boiler and one of the fixed pipes of the water circulating system adapted to receive the end of the boiler I pipe, illustrating clearly the rod movable in upon the upper face of said floor.

Fig.4 is a similar view to Fig. 3, the twopipes being separated and the movable rod withdrawn from operative position. Y

A- represents any suitable construction of fire engine adapted to be normally supported upon a floor a and having its boiler -B provided with a suitable inlet and outlet consisting preferably of projecting pipes b and b provided at their ends with check valves b the pipes-bb' being preferably provided with removable wearing ends b v cc represent a pair of fixed pipes connected at one end to a water circulating system --C and formed with the removable Wearing extremities c having the bell shaped outer end -c for receiving the wearing end -b of the pipes bb, when the portable boiler is backed into its normal position in proximity to the water circulating system. The endsc of the wearing extremities c of the pipes -c-c' are provided on their interior with suitable packingo Fig. 3, for makinga tight joint when the ends b of the pipes bb are in position, thus permitting the circulating water to How through the boiler from the water circulating system O c-c' are held fixed in any desired manner as by a bracket o having one'end formed with suitable open eyes o c for receiving the wearing extremities of the pipes and the other mounted upon the floor a, and by means of the pipes C andG presently described, to which the fixed pipes cc' are respectively secured. These pipes -O -O are passed through an opening a in the floor a, and are provided with a shoulder a**-, which rests Movable within each of said pipes -c cis a rod -D- having one extremity -dextending beyond the pipe through a bushing dand provided with a hand piece d" and the other extremity -d movable in a bearing d within the pipe and adapted to project beyond the outer ends o of said pipes and within the check valve -b* for rocking the valve piece b backwardly and opening the check Valve to'permit the circulation of the Water.

When the fire engine is returned from a fire The pipes" or other outdoor service, the operator engages the hand engaging pieces d*-- and draws the movable rods D backward until their progecting ends are within the extremities -c so that the engine may be backed into position without liability of bending said rods, and, after the engine is connected with the water circulating system by backing the same 1nto suitable proximity to the pipes -cc'-, the rods D- are then forced toward the portable boiler for opening the check valve.

In order to guide the engine in its movement upon the floor atoward the pipes -cc-- for connecting its boiler B- with the water circulating system -C I preferably use guides -a consisting of ribs proecting upwardly above the floor a. I have here illustrated only one of said guides as at the outside of one of the wheels, but it will be readily apparent that a second guide 1s arranged at the outside of the other wheel. In some cases the fire engine is drawn upon 1ts supporting floor a-- front first instead of being backed thereupon, and, as it is then necessary to reverse the position of the engine, the guides -a are formed very short and utilized to guide only the extreme rearward movement of the engine when reversed to its normal position.

"When the portable boiler is quickly withdrawn from the water circulating system, as is required in the use of a fire engine, the operator has no time to turn valves and similar 1 devices, and for this reason I have provided the check valves -b-, which close automatically and prevent the escape of water from The water circulating system C- is heated by a heating system -F, and consists,

essentially, of a series of pipes or conduits -O' mounted within a shell C suitably supported beneath the floor --aas upon a -F, which, as presently stated, forms a part of the heating system.

Upon reference to the drawings it will be or conduit C through the pipes -C -cinto the boiler l3-, thence from the boiler B through the pipes -c-C and into the lower head or conduitC The water within the circulating system is thus shut off from entrance into the chamber or conduit --F and, as previously stated, the water within the pipes -cc'- is free to escape into the catch basin E.

To permit entrance of water to the water circulating system for replenishing the waste caused by the operation of the engine in order that its boiler may be full when starting for a fire I provide a suitable inlet pipe -G- connected to thelower end of the return pipe -C and provided with a valve It is frequently necessary to remove the water from the heating system, and for permitting this operation I provide an outlet pipe G- having one end connected to the lower horizontal portion of the return pipe --C, which, it will be noted, is beneath the lower head -C and having its other end directly above a catch basin -g'- from which the water is conducted by a waste pipe g The outlet pipe -G'- is formed with a valve --g, which is closed when the water is circulating through the system -C- and the boiler -13.

The heating system -F- consists, essen of the water tank and the upper extremity of the chamber -F and the pipe or conduits F between the upper extremity of the water leg -F and the lower extremity of the chamber F The heater -F'-may be of any desirable form, size, and construction being here shown as provided with a combustion box f, a fuel inlet door an ash-box l--f", a smokepipe -f--, and as mounted upon a floor --a beneath the upper floor -aupon which the engine A-- is supported.

The shell C for supporting the pipes or conduits -G- ot' the water circulating system and containing the chamber or conduit F of the heating system is preferably supported with its upper end abovethe corresponding end of the heater by means of a suitable bracket -l'I secured to the heater section --F The feed tank -F is supported above the heater lf-- upon the floor a, and may also be of desirable form, size, and construe tion, being here shown as cylindrical and as supported upon a bracket f Upon reference to the drawings and the foregoing description of the heating system it will be evident that as clearly shown by the arrows 2 at Fig. 1 the water passes from the upper extremity of the water leg F through the pipe F into the chamber F through the pipe F to the upper extremity of the feed tank F thence through the pipe -F into the lower extremity of the water leg F Water is admitted to the heating system by a pipe I- discharging into the lower end of the pipe F and formed with a valve 1I--, and is withdrawn from said system by an outlet pipe I having one end opening from the base of the water leg F and provided with a valve i and the other discharging into the catch basin g'.

It will be particularly noted that the water or' other fluid used in the heatingsystem is entirely shut off from the water of the-circa lating system so that the circulation within the heating system continues constantly without being affected by the presence or removal of the portable boiler B-, whereas the removal of the portable boiler -B breaks the circulation of the water circulating system. This construction enables the firemen or other attendantsof the heating apparatus to use the water from the circulating system for bathing orother purposes, without permitting thewithdrawal of the water from the heating system and thus affording a liability of the same being unduly burned through lack of water therein.

The operation of my invention will be readily perceived from the foregoing description and upon reference to the drawings, and it will be particularly noted that the parts are simple, strong and effective, and well suited for the designed purpose; that the water of the circulating system is entirely shut off from that of the heating system; that a constant circulation is passed through the boiler of the engine when in position, and that the same may be readily withdrawn without the operation of any valves or liability of escape of water from the boiler of the fire engine.

It is evident that the detail'construction and arrangement of the parts of my heating apparatus may be somewhat varied from that shown and described Without departing from the spirit of my invention, hence I do not herein limit myself to such precise detail construction and arrangement.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
