SPECIFICATION forming part 0f Letters Patent NO. 605,240, dated J une '7, 1898.
Application filedJanuary 29, 1898.. eral No. 668,423. f (Noinodel.) i
To @ZZ whom it may concern:
Be it known that I, CHARLES IV. TROTTER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Furnaces; and I do hereby declare the following to be a full, clearpand exact description of the same,ref erence being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.
My present invention relates to hot-air furnaces, and has for its object to improve their construction and operation, whereby the heat derived from the combustion of the fuel may be economized and thoroughly distributed and all the apartments evenly heated irrespective of the length or inclination of the conductorpipes; and to these ends it consists in certain improvements and combinations of parts, all as will be hereinafter fully described, and the novel features pointed out particularlyin the claims at the end of this specification.
In the drawings, Figure 1 is a longitudinal sectional view of a furnace containing my improvements; Fig, 2, a cross-sectional view, and Fig. 3 a horizontal sectional View onthe line w of Fig. 2.
Similar reference-numerals indicate similar parts.
The furnace proper embodies asuitable body l, preferably rectangular and having the firebox 2, lined with fire-brick 3, as usual, the
of Fig'. l. ployed for holding the collars-as, for in- `tached to the ends of the pipes 8 are dependingair-supplypipes 14, preferablyof sheet metal, extending toward the bottom of the furnace, but within the outer casing 15, and adapted-to receive air, which enters said casing through the cold-air pipe 16 or otherwise, and cause it to rise through the pipes 8 and the extensions 12.
17 and 18 indicate conductor-pipes connected to the upper portion of the casing 15 and ar-` ranged to receive the Warm air and distribute it to the various chambers, and 20 are movable collars sliding upon the upper ends of the extensions l2 and preferably longer than the distance between said extensions and the conductor-pipes 18, arranged over them and constituting a direct connection between the extensions 12 and the conductors. The air drawn into the pipes 14 is heated in the pipes 8, which are directly over the fire, and delivered directly intothe conductor-pipeslS, so that each of the latter may be supplied ,with sufficient'hot air irrespective of its length or inclination. I have shown four pipes 8 and corresponding conductor-pipes 18; but it will be understood that a greater or lesser number could be employed, if desired, and the length of the furnace increased or diminished. The pipes 18-are provided with suitable dampers 2l, by means of which they can be closed when desirable "or necessary, and in order that the heated air fromthe pipes 8 whose conductors are closed may beutilized the collars 2O are adjustable, so as to permit pipes 8 and 12 to discharge into the casing 15 and the heated air be permitted to pass through the general conductors 17 or through others of the conductors 18 whose connecting-collars 2O are open, as shown at the right Any suitable devices may be emstance, notched rods 22, coperating with the sides of suitable apertures formed on the casing 15.
The smoke-pipe of the furnace (indicated by 23) is preferably arranged at the rear and upper part of the furnace, and the pipes 8, in connection with the top of the furnace, form a smoke-flue. If said pipes 8 are arranged as far apart as shown or are made round, I close or partially close the spaces between them and also between the last pipe of the IOO series and the rear of the body by means of plates or slabs 24, preferably provided with apertures 25 to permit the escape of gas. A space is left between the front pipe 8 and the casing, so that all the heat and products from the fire will operate upon the lower sides of all of the pipes 8, then pass to the front and over said pipes to the smoke-pipe, thereby eifectually heating them on all sides and also the upper part of the furnace-body, thus utilizing in the best possible manner all the heat derived from the fuel. By making the plates 24 flush with the top of the pipes 8 and providing a cleaning-door 2G in the front of the furnace the tops of the pipes and the smoke-flue formed thereby may be readily cleaned, the contents being drawn forward and permitted to drop directly into the firebox.
The size and capacity of the furnace may be increased as desired by the employment of additional pipes 8, with their attachments, and by the damper arrangements shown any or all of the conductor-pipes 18 may have a separate direct supply of hot air, thus obviating the difculty incident to the use of the ordinary furnace, in which all the conductors are supplied from the surrounding casing, and the supply of hot air from some conductors will be Very voluminous and from others very meager.
Other forms of damper and connections between the pipes 8 and the conductors l18 may be employed instead of the adjustable collars 20; but those are simple and cheap inconstruction and I prefer them for this reason.
By arranging the pipes 8 so that the heated products from the lire pass under and over them they are not liable to burn out and at the same time they are thoroughly heated a all times.
I claim as my invention- 1. The combination with the furnace-body having the fire-box and smoke-pipe, of the pipes arranged substantially horizontally over the fire-box provided with the vertical extensions, the partitions therein, and the depending supply-pipes at the ends, the outer casing, the conductor-pipe leading therefrom, and means for connecting the extensions directly with the conductors, substantially as described..
2. The combination with the furnace-body having the fire-box and the smoke-pipe, the horizontal air-pipes arranged over the rebox, and forming a smoke-Hue between said as described.
4. The combination with the furnace-body and the fire-box and smoke-pipe, of the horizontal air-pipes extending over the lire-box and below the smoke-pipe and forming a flue at the l[op of the body and between it and the pipes, a casing around the furnace-body, conductor-pipes leading from the top thereof, and detachable pipe connections between the horizontal air-pipes and the conductor-pipes, substantially as described.
5. The combination with the furnace-body having the fire-box, the horizontal air-pipes 'arranged above the fire-box having the vertical extensions passing through the furnacebody, and the partitions therein, of the outer casing, the conductor-pipes connected thereto and having dampers therein, and means for connecting the vertical extensions of the horizontal pipes directly with the conductorpipes or permitting them to discharge into the casing, substantially as described.
6. The combination with the furnace-body having the iire-box, the horizontal air-pipes .arranged above the fire-box, having vertical extensions passing above the furnace-body, of the outer casing, the conductor-pipes leading therefrom, the vertically-adjustable collars cooperating with the pipe extensions and with the conductor-pi pes, substantially as described.
7. In a furnace, the combination with the furnace-body, andthe fire-box, air-pipes passing over the fire-box and discharging above the furnace-body, of the outer casing, the conductor-pipes connected therewith and adj ustable collars for connecting the pipe extensions with the conductor-pipes, substantially as described.
