AIR-HEATINGAPPARATUS.
SPECIFICATION forming part of Letters PatentNo. 558,215, dated April 14, 1896..
Application filed November 26,1895. berial No. 570,163. (No model.)
To all whom it may concern:
Be it known that I, CHRISTIAN P. SHIND- LER, a citizen of the United States, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Air-Heatin g Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in air-heating apparatus, and its novelty and advantages will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which- Figure 1 is a front elevation of the lower portion of my improved apparatus as it appears when placed in a dwelling-house or other building. Fig. 2 is a horizontal section taken in the plane indicated by the line as a:
of Fig. 1. Fig. 3 is a vertical section of my improved apparatus complete, taken in the plane indicated by the line y y of Fig. 2. Fig. 4 is a vertical section taken in a plane at right angles to Fig. 3; and Figs. 5, 6, and 7 are sectional views taken in the planes indicated by the lines 1] 3 z z, and w w, respectively, of Fig. 4.
Referring by letter to said drawings, A indicates the chimney or smoke-uptake of my apparatus, which may be built in the wall of a building like an ordinary chimney or uptake. B indicates the casing of the apparatus, which may be built of brick or other suitable material in the wall of a building and at the side of the chimney or uptake. 0 indicates the floor of an apartment in the building, and D indicates the fire-chamber, which is arranged in the casing B immediately above the level of the apartment-floor O, as illustrated. metal, and is preferably of a general rectangular form in cross-section, and it is so arranged in the casing B as to form an upright airpassage E between its rear wall and the rear wall of the casing, which passage is designed to conduct air past the fire-chamber to heat the air, and is preferably provided with plates, as d, designed to retard the upward passage This fire-chamber D is formed of of the air, so that the same will be Well heated before passingabove the fire-chamber.
The chamber D is provided at about the distance shown above the floor-level with a grate-frame F, which has eyes a, designed to engage hooks b on the fire-chamber walls, as shown. This grate-frame F, as better shown in Fig. 3, is provided with a dumping-section G, which is pivotally mounted in the frame and is designed and adapted to be turned through the medium of a suitable implement applied to one of its trunnions, and is also adapted, by reason of its pivotal or fulcrum point being arranged as shown, to automatically resume its proper operative position when released. The fire-chamber D is also provided with a protective lining of asbestos H, which extends about the proportional distance illustrated above the grate, and said firec-hamber, furthermore, has its front wall provided with the damper I for admitting air below the grate, the reversible folding doors J, which afford access to the interior of the fire-box for charging it with fuel, and which comprise a series of sections 0, connected together and to the wall in a hinged manner, and the upper proportionately small doors K, which are, for the sake of appearance, provided with mica lights, as shown. The sections 0 of doors J are connected in such a manner that the outer section may fold in or out with respect to the inner section, and hence I term said doors reversible folding doors.
L indicates dampers arranged in the bottom wall of the fire-chamber D and designed to be opened to feed air to the fire, and. Mindicates a chute, which is designed to convey ashes from the fire-chamber through the airchamber (presently described) and is provided with a pivoted dumping-plate P, which is designed to be turned when ashes are to be dumped into the ash-pit N atthe base of easing B and to be closed, as shown in Fig. 3, when the apparatus is in operation.
Q indicates a plurality of hot-air pipes, which communicate with the casing B and are designed to lead the heated air to any desired point or points in a building, and R indicates a smoke-conductor, which communicates at an intermediate point of its length and at its upper end with openings 6 f, formed in the wall between the chimney A and the casing B, as shown. The opening 8 is closed by a damper g, as shown, when a strong draft is not required, and the conductor R is preferably serpentine, as illustrated, so as to enable it to radiate the major portion of the heat in the smoke before the smoke reaches the chimney A. In consequence it will be seen that the air which passes up the passage E and through the screen S, at the upper end of said passage, will, before it reaches the hot-air pipes Q, be further and highly heated.
In order to prevent a too-free escape or passage of heat up the conveyerR, I provide the damper T. (Better shown in Fig. 3 of the drawings.) This damper T is pivoted in the side walls of the fire-chamber D, as indicated by h, and it has its upper end weighted, as indicated by 1', so that it will of itself remain in the positions to which it is adjusted. hen said damper is in the position shown by dotted lines in Fig. 3, a free passage is afforded to the conductor R. This is highly desirable when the fire is first started or when fresh fuel is placed in the fire-chamber but after the fire commences to burn well it is desirable to ad just the damper T to the position shown by full lines, so as to retard the passage of heat and particles of combustion to the conductor R, and thereby enable the fire-chamber to radiate a portion of its heat into the apartment in which it is placed.
U indicates an oven, which is arranged immediately above the fire-chamber D and is provided with doors 70, (see Fig. 1,) having a pan U in the inside for water for moistening the hot air and attracting poisonous substances, and V indicates what I term the foul-air chamber, because it is designed to be connected with one or more apartments by a pipe \V, so as to receive impure and cold air therefrom. This foul-air chamber is connected with the passage E by an opening on, controlled by a damper X, and this damper is sov arranged as to control communication between the chamber V and the passage E and communication between the fresh-air-induction pipe Y and said passage E, the arrangement also being such that when communication between the cylinder V and passage E is established communication will be closed between pipe Y and'passage E, and vice versa. The oven-doors 71, also have upper panels provided with registers as shown.
As will be readily observed byreference to Figs. 1 and 2, the fire-chamber D and oven 3 B extend but a slight distance within the apartment, so as to take up but a minimum amount of the space thereof, and they are such a height as to admit of them being placed beneath a mantelpiece Z, which may be ornamented so as to enhance the appearance of the apartment. For the same purpose the front of the fire-box and oven may be ornamented in a suitable manner.
In the practice of the invention the pipe IV is preferably connected with the apartment or apartments to be heated at points adjacent to the floor thereof, so as to receive the cool and impure air which occupies the space adjacent to the floor. The pipe or pipes Q, on the other hand, are connected with the apartment or apartments adjacent to the ceilings thereof. In consequence of this it will be seen that when the damper X is in the position shown by full lines in Fig. 3 the fresh air will pass from the open air through the pipe Y, passage E, and the upper portion of the casing B to the pipes Q, and from thence into the apartment to be heated. This air is highly heated in its passage through the casing 13, and it displaces the cool air in the compartment. This cool air and impure air passes through the pipe IV to the chamber V and from thence passes up through the dampers L into the fire-chamber D and serves to promote combustion of the fuel. In this way the apartment or apartments are continuously supplied with fresh heated air and are continuously exhausted of cool and impure air, and this without creating a draft. When the damper X is adjusted to the position shown by dotted lines in Fig. 3, the air will circulate continuously through the apartment or apartments tobe heated and my improved heater and will in consequence be highly heated. This mode of procedure is desirable when the weather is very cold, and when the atmosphere becomes impure fresh air may be admitted by moving the damper X to the position shown in full lines for a short time.
In addition to heating one or a plurality of apartments with the consumption of but a minimum amount of fuel, my improved apparatus is highly desirable, because the necessity of removing the ashes from the firebox into a receptacle placed on the floor O is obviated. As stated in the foregoing, the
ashes falling from the grate are dumped into the ash-pit N, which may be in the cellar of 'a house and may be provided with an open- 1 ing through which the ashes may be removed when necessary. In this way it will be appreciated that the ashes may be removed from the apparatus without soiling the carpet or furniture of the apartment in which the apparatus is placed, which is an important desideratum.
The even U comprised in my improved apparatus may be used for baking as well as heating articles of food.
Having described my invention, what I I claim is 1. The heating apparatus described comprising a casing, the fire-chamber having a grate and arranged in the casing and serving in conjunction with the same to form a passage E, the foul-air chamber arranged below the fire-chamber and connected therewith by j a damper-controlled opening, a smoke-conductor arranged in the casing and connecting the fire-chamber and an opening in the easing, a pipe WV, connected to the foul-air chamber and adapted to be connected with an apartment, a hot-air pipe connected with the interior of the casing and adapted to be connected with an apartment, a fresh-air-induction pipe leading into the casing and a valve for controlling communication between the fresh-airinduction pipe and the passage E, and communication between said passage E, and the foul-air chamber, substantially as specified.
