CHARLES B. RICE, OF CHICAGO, ILLINOIS.
STEAM AND HOT-WATER BOILER.
SPECIFICATION forming part of Letters Patent No. 351,070, dated October 19, 1886.
Applcation filed April 29, 1886.
To all whom it may concern.-
the following is a specification.
This invention relates to improvements on i the apparatus described in Letters Patent granted to Mortimer B. Mills and Charles B. Rice, assignors to Rice, No. 232,101, September 7, 1880, feedcookers, the apparatus de scribed in said invention having been mainly used for generating steam for cooking feed.
By means of the improvements herein described I utilize the apparatus for generating steam for the purposes of heating buildings, heating water, running engines and machinery, and for all purposes for which steam, either at high or low pressure, can be used. I also utilize the apparatus for heating water by circulation for the purpose of heating buildings, and for all other purposes for which hot water can he used, the object of my invention being to provide, first, a compact and self-contained apparatus of the water-tube style of boiler, simple in oonstruction,and with the tubes and other parts so arranged that a large area of heating-surfaceis obtained within asmall compass, and at the same time a large economy of fuel is secured and the fuel is utilized to the greatest advantage; second, an apparatus so constructed that it can be easily put in repair, if occasion require, with common tools and by ordinary workmen, which is easy to take care of and regulate, insomuch as it is built in such a manner that appliances can be easily attached to it for the automatic regulation of the water and fuel supply and steam-pressu re, as shown by my automatic valve and float, self-feeding fuel-magazine, and my automatic dampers; third, an apparatus which, when employed as a water-circulator or to heat water by circulation through it, by reason of the vertical position of the water-tubes and the unobstructed form of the water-spaces, together with the large amount of surface exposed to the action of fire, produces a rapid and perfeet circulation of the water through the-boiler and connectingpipes and radiators. I attain these objects by means of the apparatus shown in the accompanying drawings, in which- Serial No. 200,537. (No model.)
Figure 1 represents a sectional view of my apparatus, showing also the manner of attaching my valve and float for the automatic regulation of the water-supply. Fig. 2 is a sectional view of my combined safety and vacuum valve; Fig. 3, a horizontal view ofFig. 2, looking upward from the base of the View. Fig. at is a modification of my apparatus arranged with my dampers for automatically regulating the drafts to control the steam-pressure, and arranged with fuel-magazine to supply the fuel automatically. Fig. 5 is a sectional View of my apparatus when used as a watercirculator or for heating water by circulation through it.
The details of the construction and arrange ment of my apparatus are as follows, similar letters referring to similar parts throughout the several views.
The boiler consists of a hollow ring shaped casting, B, and water-front 13, connected with lower section of steam-dome A by a circular row of tubes. The sheet-iron or steeljacket E surrounds the tubes and waterfront and with them incloses the furnace.
O is the fuel-door.
The water-tubes C C are screwed into the base B and water-front B, and are connected at the bottom of dome A by a joint with double lock-nuts, or made with right and left threads and screwed into base and dome. The Waterfront B is connected with the casting B by a short piece of pipe.
The dome A consists of two hollow ringshaped castings, the openingsthrough which, formed by the inner conical tube of the castings, form the smoke-flue D from the furnace. The two castings for the dome are provided with flanges A A and held together by bolts, the joints being made water-tight by the packing P P. In the center of the casting B is placed the grate G, under which is the ashboX F. To the rod of the damper U is suspended the flame deflector T. R is the floatboX, containing the valve and float for automatically regulating the water-supply.
H is a pipe running from float-box through one of the tubes, and used to convey to the base the water for supplying the boiler.
K is the watersupplypipe; S, the valve for emptying the boiler.
I from aperture to.
5 In the modification shown in Fig. 4 I place the fuel-magazine V Within the smoke-flue D.
The smoke thus passes on the outside of fuelmagazine V and out through the pipeD at the point where the damper m is shown. t represents the cover to the fuel-magazine wherein the fuel is placed. When the pressure of the steam in dome Ais sufficient, itforces the water up the pipe 9 to the diaphragm contained in box 9, and the movement of the lever coni 5 nected therewith closes the damper in the pipe D and draftdoor it, connected by the chain, as shown.
In Fig. 5 my apparatus is shown when used as ,a water-cireulator, or for heating water by circulating the water through it in con nection with atank for heating water, or in connection with a coil of heatingpipes or radiators. The dome A in this modification is filled with water at all times and no steam is generated, the water 2 circulating through the entire apparatus and connecting-pipes.
In Fig. 2 I show the construction of my combined safety and vacuum valve. n represents the safety-valve weight; a, the aperture 0 in which rests the plunger 0; e, the seat; d, the
safety-valve; 7c, the valve-case; b, the casein which is placed plunger 0; h, the channel from dome to aperture a.
When the pressure of the steam is sufficient,
it raises the safety-valve and the steam'escapes below the seat 6, thus forming the ordinary safety-valve. thread, as shown, for attachiugit to the boiler. The aperture a in safety-weightn contains the 40 case b, in which is placed the plunger 0, as
shown. The upper part of valve (1 forms the seat e, and to the seat a is attached case b. Safety-weight n incloses case b and rests upon seat 0. Seat 0 is provided with grooves, as
' 5 shown in Fig. 3, and is provided with channel h, opening into valve d, so that when plunger 0 rests on 6 there is a free passage of air from the outside into aperture a, the grooves in seat 0, channel h, and valve d into theboil- When steam is up a very slightpressure will raise the plunger 0', so as to close the aperture a, thus preventing the escape of steam and condenses in the boiler, the steam-pressure is removed and the plunger 0 drops back onto seat 0 and allows the air to pass down The valve-case It has a When the steam goes down through aperture a, grooves in seat e,channel h, and valved into boiler. The formation of a vacuum in theboiler is thusprevented and the-annoyance from the suction back into the boiler obviated.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, 1s I 1. Theimproved steam boiler'and heater, consisting of the hollow ring-shaped casting B, water-front B, steam-dome A, consisting of two castings, and constructed with flanges A A and packing P P, smoke-flue D, jacket E, door 0, water-tubes G C, grate G, ash-box F, damper U, and supporting flame-deflector T, substantially as shown and described.
