12,011,205 p DOMESTIC-WATER, BOILER 1 Ivan Turner, Richmond, England Application September '1, 1934, SerialNo'. 743,142 V t In Great Britain March 15, 1934 8 Claims. (o1.12 s '132) This invention relates to domestic water boilers for houses or apartments with self-contained (hot water supply, and more particularly to cokejfired or like boilers which are employed for supplying hot water' 'for baths, radiators and other domestic purposes, independently-cf cooking stoves; these independentboilers, as commonly fitted in kitchens or living rooms, are* open to the objection that they do not provide the comfort of open fires, but on the other hand they may render the rooms unnecessarily warm when.

used tosupply-hotwater during the summer months.

The main object of the present invention isto provide for the supply] of hot water from the independent 1 boiler, without inevitably heating the kitchen or other' room in which the boiler is fitted, and for the separate or controlled-heating of theroom, without requiring a second fireplace recess and flues, the apparatus employed being adapted to take the place of the ordinary independent boiler; 7

According to this invention, I provide a hot water boiler of the independent type, that is in dependent of a. cooking stove, with which boiler I combine an open fireplace having its framework combined with that of theboiler. In the back of the open fire place, which conveniently forms part of the boiler front and may slope forward from above the level o'fnthe burning fuel towards the top front of the boiler, I provide a hinged or detachable door or doors, giving access to the front bars of the boiler fire, so that these bars can be removed 'forcleaning or laying the boiler fire; normally the door or doors will be kept closed, so as to retain the. heat, but they may be left open when the boiler fire is burning, if it be desired to warm the room when the open fireplace is not in use; The boiler. firebox is .fittedwitha loose grid or bottom bars, which i may be of the rocking 'or oscillatingqtype for front of the open fireplace. t The invention is hereafter described with refriddling the fire, with. control means at the jerence to. the accompanying drawings, in

Fig. 1 is an elevation showing the open fireplace as seen from the front, parts being broken Fig. 2 is a plan of the boiler, showing the 'flues 1 in section.

is arranged behind the open fireplace b, as clear- '10 ly seen in Fig. 3. The sloping back of the open fireplace is arranged to form part of the boiler frontc, which extends across the full width of the boilerand may support the back fire-brick b of the open fireplace the sloping part bulg- 5 'ing forward above the level of this fire-brick and extending towards the top plate (1 of the boiler which overhangs the open fireplace. The side frames e (see Fig. 4), which support the firebrick cheeks b of the open fireplace, are'tied together by a flanged plate 2 secured by setscrews c these side frames e are arranged flush with the sides of the boiler" so as to form extensions of the correspondingfboiler walls, and their rear edges areshaped to fit against the sidesof the boiler front c. Ifhe front frame ,1

of the open fireplace extends up as far as the top plate (1 of the boiler, its transomf supporting a hood or canopy 9 above the open fireplace. 'The frame members e f and the boiler "front 0 are secured tothe boiler by means of long horizontal studs h screwed into the boiler walls at the upper iand'lower frontcorners of the water spaces, with nuts h fitted to the ends of v these studs projecting through the'frame f; the

fianged'plate e is also secured to the boiler "front c by bolts 6? at the back of the open fireplace.

In the sloping portion 0 of the boiler front,

there'is provided a, rectangular opening 0 into which thefront bars 2' of the boiler fire are'fitted;

' these bars serve to retain the fuel heaped up on the boiler fire, it being customary to stoke boil- "ers of this kind at long intervals, say every'twelve hours. The bars iwhich may be separate or cast together, are accommodated inside the bulge in which the opening c -is formed and are held in place by notches c at the upper and'lower ends of the opening, the bars being removablethrough "theopening'qc (after lifting the bars clear of d the lower notches) for cleaning or laying the boiler fireL The opening c which thus gives access tothe boiler firebox, is adapted to beclosed by a jdetachabledoor or doors 7' provided with books 7' at the sides, these hooks engaging over wedge-shaped lugs c on the edges of the opening; a hole or holes 7' may be provided on the front of the door to facilitate its removal and. replacement.

The boiler is fitted with bottom fire-bars in the form of a loose grid 70 which rests upon lugs or ledges k cast on the inner walls of the boiler a (see Figs. 3 and 4); beneath this grid, there is provided a transverse shaft Z supported on two brackets l secured to the boiler front 0, the shaft having two pairs of oppositely extending arms Z connected by transverse bars Z lying beneath the grid is towards its front and rear ends. A crank arm m dependent from the middle of the shaft 1 is connected by a rod m to a knob or handle m at the front of the grate, so that the boiler fire can be shaken or riddled by oscillatting the shaft Z so as to rock the grid is. I a The open fireplace I) is shown as fitted wit a removable grate bottom it having rear supports n secured upon the flanged plate e the 'front edge n of the grate bottom is turned up to hold the fuel in place and it is supported for example on pegs f projecting inwardly from the frame 1, the underside of the grate bottom being notched at f? to fit over these pegs so that it cannot slip forward accidentally.

In the bottom of the frame, and extending from front to rear under both fires, there is fitted a large ashpan o, the front 0 of which is provided with a handle 0 and a suitable draft-regulator o for controlling the admission of air to the boiler fire; the front 0 may also be notched at 0 for the passage of the rod m which is guided at this point by a hole or eye m is a vertical rib e below the front of the flanged plate e Above this ashpan and underneath the open fireplace, I provide a second ashpan p carried on the flanged plate 6 which is of open hexagonal shape, as seen in Fig. 5, the pan p normally covering this opening, so as to exclude all draft from above this pan into the boiler fire, and also from below this pan tothe open fire, and the air for the latter being admitted through a regulating shutter p inthe front p of this second ashpan, which is fitted with a handle p The ashes collecting in the second pan p can be tipped into the large bottom ashpan o by sliding the former outwards, as indicated in Fig. 4, and tilting it up, a scraper bar p? hinged at n beneath the grate bottom it serving to clear the pan as itis drawn out, and the ashes then falling through the open center of the plate e into the bottom ashpan o.

The water spaces at the vertical sides a of the boiler increase in width from the line where the sloping portion 0 of the boiler front begins to bulge forward over the open fireplace b; thus there is a relatively small firebox at the bottom of the boiler, but from a few inches above the bottom bars 70 the combustion space widens out towards the front, as can be seen in Fig. 3, so that ample heating surface and fuel capacity are provided. An opening :1 in the fiat top plate at of the boiler allows fuel to be added after removal of the lid d the smoke outlet q being located directly behind'the firing'hole 11 Suitable tappings r r 1' for the flow, return and drain-off water pipes are provided, togetherwith one or more manholes r if desired.

- The combustion gases from the open fire place 1), which forms the front of the combined apparatus, escape from the top of the slopingback c and beneath the boiler top plate (2, which extends over the open fireplace, into horizontal fiues s at the two sides of theboiler and thence ordinary open fireplace, as seen in Fig. 1., and at the same time to retain the heat radiated from the exterior of the boiler a; the space above the boiler top plate d may then be closed in by extending the front frame 1 upwards above the canopy g and providing a hinged door m, which when opened (as shown in dotted lines in Fig. 3) allows the fuel to be fed to the boiler; a handle 10 with a suitable catch enables the door to be opened and closed, hinged door stays 10 being provided if desired. If preferred, however, I may dispense with the door 10, and leave the space above the boiler open as illustrated in Fig. 6, the top plate d of the boiler being in that case formed with a suitable beading d or the like. A guard fence may be placed round the sides and back of the firing hole 01 or this fence may be arranged at the edge of the top plated, as indicated at a: in Fig. 3.

The boiler a and front frame i may rest upon a base 1 at the front of which there is arranged a loose tray 2 to catch any cinders falling from the ashpans or from theopen fireplace.

'By this combination of an open fire place b with the hot water boiler a, I provide a highly adaptable boiler, which can be employed not only independently of the cooking stove, but either alone, with or without heating of the room by opening or closing the door 7' above the open fire place, or in conjunction with the open fire when the room requires heating, or can be put out of operation, the heating of the room being then provided, if required by a fire in the open fire place I) alone. Under normal conditions, the boiler will be maintained in operation for supplying hot water for domestic purposes; the heating of the room will then be provided by the opening 0 part of the heat from. the boiler combustion space being transmitted into the room. When heat from the boiler combustion space is not needed to heat the room, the door 7' will be closed; similarly the door 7' will be closed whenall of such heat is required to heat the water in the boiler, but in this case a separate fire can also be provided in the open fire-place, if heating of the room is desired. Lastly if the boiler is out of operation, and it is required to warm the room without delay or for a short period, a fire can be lighted in the open fire place alone. Both fires are preferably arranged to burn the same fuel, e. g. coke, anoz either or both may be provided with gas ignition means, as indicated at b in Fig. 3, but it will be understood that either the boiler or the open fire place, or both, may be gas-fired, suitable supply pipes and burners being provided as well known in the art.
