HEATER.
Specification of Letters Patent. Patented June 14, 1910,
Application filed October 12, 1908. Serial No. 457,384.
To all whom 'it may concern:
Be it known that I, R NOLDS O. FRAME 'roN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Heaters, of which the following is a specification.
The invention relates to heaters and particularly to hot Water heaters for use in house heating systems, and has for its primary objects; the provision of a simplified and eflicient heater which may be used with .either gas or solid fuel without any change or alteration of the parts whatever; the provision of a heater of the character speclfied wherein, radiation from the heater casing is reducedv to a minimum; and the provision 'of a heater wherein both solid and gaseous fuel may be used efficiently together and the temperature of the water automatically and positively regulated. One embodiment of the invention is illustrated in the accompanying drawing, wherein "The figure 1s a longitudinal section through the heater.
Heretofore heaters capable of using both gas and solid fuel, such as coal or wood,
have been constructed, but the constructions have been such that considerable alteration was necessary in order to change from one form of fuel to the other, such as the removal of the gas burners to permit coal to be used, and the removaliof the coal grate to ermit the installation of the gas burners.
This changing is a matter of inconvenienceand difficulty, and my invention is intended to obviate the difficulty by the provision of a construction in which the combustion chambers for gas and solid fuel are entirely independent .and separate, so that the grates and urners may be left fpermanently in position, and either solid uel orgas may be burnedf Without the necessity of removing the partsnot in use. Another objection to the majority of the old arrangements whereinthe: fuel was interchangeable, arose from R'eferring first to the general arrangement, shown in the drawing, 1 is the casing of the heater provided at its upper end with the outlet flue 2; 3, 4, 5 and 6 are vertical coils verse pipes; 10 is the outlet pipe leading to,
the radiators; 11 is the return pipe from the radiators; 12 is the combustion cham her for the solid fuel, whichchamber is provided with a grate 13 beneath which is the ash pit 14; 15 is the gas combustion cham-' ber provided at its lower end with a set of burners l6 fed from the gas pipe 17; 18 and .l
19 are water containing walls, 20 is the pipe leading from the upper portion of the water containing wall 18 to theleft hand end of the transverse pipe 7 21 is a pipe leading from the lower end of the return pipe 7 t0 the lower portion of the water containing wall 18; 22 is a thermostat rod carried by a copper tube extending'into the transverse pipe 7 whereby the flow of gas through the pipe 7 is automatically controlled; and 23 is a manually operable valve for controlling the flow of gas through the pipe 7. I
The thermostat rod 22 operates the valve disk 21 through the medium of the cooperating levers 25 and 26. The particular kind of thermostat employed is immaterial as far i as the present invention is concerned, and Wlll therefore not bedescribed in detail. A
"pilot light 27 is preferably employed, and this pilot light is supplied by means of the pipe 28 which connects with the gas pipe above the valve 23. The water containing walls 18 and 19 are connected together by means of thepassages 29, 30, 3 1, 32, 33, 34 and 35, so that an effective circulation may be had. The gas combustion chamber 15 located intermediate the Water containing walls 18 and 19 opens at its u per end into the casing just beneaththe 001 s 3, 4, 5 and (3, and the heat not'absor'bed by the Water containing walls passes up about the copper coils, the products of combustion pass ng through the flue 2.
In \operation the water heated in the water containin walls 18 and 19 passes u through t e pipe 20 to the transverse pipe? and thence outthrough the outlet pipe 10. 116
the coils.
. or throughout the heater.
The water heated in coils 3, 4, 5 and 6 passes upward therethrough and out into the transverse pipe 7 and thence through the outlet pipe 10. On the return through the pipe 11, part of the water passes down through the pipe 21 to the lower portion of the. walls 18 and 19, while another portion of the water is diverted laterally into the transverse pipe 8 from which it passes into It will be seen from the foregoing that a proper circulation is provided The advantages of the construction will be readily apparent. 5 Solid fuel may be burned upon the ate 13 without in,any way interfering with the operation of the burners 16, and the burners 16 may be operated without interfering with the use of solid fuel upon the gr'ate13. The two kinds of fuelmay'be used separately or if desired, both fuels may be used at the same time. The latter method of 0 eration is advantageous when it is desire to heat the water very rapidly, or in casethe as pressure is low and insuificient to provi e the requisite amount of heat. It will be noted that by making the two combustion chambers en-,
tirely independent there is no necessity of any alteration or rearrangement of the parts when it is desired to change from one. fuel I to another, and that the shape of the chambers is such that an.efiicient o eration is insured when either class of fue is employed.
The use of the water containing walls 18' and 19 reduces the amount of radiation fro'm at a uniform temperature regardless of the condition of the fire upon the grate. Other advantages incident to the construction will be Iaipparent to those skilled in the art.
aving thus described myinventi'on and illustrated its use, what I claim as new and desire to secure .by Letters Patent is the following 1. In combination in a water heater, a.
container for water to be heated, and two independent combustion chambers arranged in telescopicrelation w1th an interposed water containing wall in communication with the container, the chambers being positioned so as to. supply heat to the container and the inner chamber being provided with a grate for solid fuel and the outer onewith gas heating means. I 2. In combination .in a water heater, a.
container for water to be heated, and two independent combustion chambers arranged containing Wall outside the outer chamber.
