AIR-H EATER.
SPECIFICATION fOrming part of Letters Patent No. 553,750, dated anuary 28, 1896.
Application filed March 9, I894.
DOHRMAN, of Steubenville, in the county of J efferson and State of Ohio, have invented a new and Improved Air-Heater, of which the following is a full, clear,and exact description.
The object of the invention is to provide a new and improved air-heater for conveniently Figure 1 is a front elevation of the improvement. Fig. 2 is a transverse section of the same on the line 2 of Fig. 1. Fig. 3 is a sectional plan View of the same on the line 3 3 of Fig. 2. Fig. 4 is a similar view of the same on the line 4.- t of Fig. 1. Fig. 5 is an enlarged front face View of the regulating device for the dampers, and Fig. 6 is a transverse section of the same on the line 6 6 of Fig. at.
The improved air-heater is provided with an open fireplace A, of an approved construction and built in the wall B in the usual man ner, the said fireplace being provided with a grate 0 containing the fuel to be burned for heating the rooms in the building, as hereinafter more fully described.
The upper end of the fireplace A is closed by a cap D, from which leads a series of pipes F extending upwardly .in a shaft E preferably made in the shape of a chimney, but disconnected entirely from the interior of the fireplace A by the cap D. The flues F are adapted to be closed at their lower ends by the valves F, pivoted on the under side of the cap D, as plainly shown in Fig. 2, the said valves being provided with knobs F arranged on one side of the wall, so as to be under the control of the operator to open or close the said valves to regulatethe escape of the smoke, gases and other products of combustion from the burning fuel in the fire- Serial No. 502,996. (No model.)
place A to the said flues F. The latter are supported in the air-shaft E by one or more open spiders or grates G, and the upper ends of the said flues discharge into a soot-receptacle H held in the extreme upper end of the airshaft E and discharging through the shaftcap I into the outer air above the roof of the building. A similar soot-box H is arranged in the cap D directly below the fiues F, so that any soot passing down the said flues collects in this soot-box and is not liable to pass into the room.
The air-shaft E is preferably lined interiorly with tiles or other suitable non-conducting material, and into the lower end of the said air-shaft leads a flue J connected with the outer air, as plainlyindicated in Fig. 2, so that fresh air from the outside can pass into the lower end of the said air-shaft to be heated therein by coming in contact with the flues F heated by the escaping gases, smoke or other products of combustion passing through the said flues from the fireplace A, as above described.
In the fresh-air-inlet flue J is arranged a damper K provided on its stem with a knob K extending into the room in which the fireplace A is'located, so as to be under the control of the operator, to permit the latter to open and close the said damper K, to regulate the amount of fresh air passing into the air-shaft E and up the same to be heated, as previously described.
From the air-shaft E lead registers L into the several rooms to be heatedthat is, rooms located above the room in which the open fireplace is situated, the said rooms also being alongside the said shaft E, as will be readily understood by reference to Fig. 2. The registers L are of any approvedconstruction and eachis provided on one of its trunnions with a knob L under the control of the operator in the room in which the register is located so that the operator can regulate the amount of heated air passing into the room.
In order to regulate the burning of the fuel in the open fireplace A and the escape of the products of combustion passing from the open fireplace into the several flues, as above described, I provide a hinged damper-plate N made of suitable non-conducting material and formingthe back for the fireplace A, as plainly indicated in Figs. 1 and 2. This plate N is secured at its lower end on a pivot N journaled in suitable bearings in the sides of the fireplace A, the outer end of the said pivot being provided with a knob N under the control of the operator, so as to permit the latter to swing the plate N into any desired angular position directly over the burning fuel in the fireplace A. On the upper or free end of the plate Nand at the sides thereof are journaled friction-rollers N adapted to travel on segments N secured in the sides of the open fireplace A. The downward-swin gin g motion of the plate N is limited by the upturned ends N formed on the segments N and adapted to engage the rollers N whenever the latter swing into a lowermost position.
In order to enable the operator to set the plate N or the valves F or the damper K or the register L into any desired position, I preferably provide the knob of each of the said devices with a fixed pin 0, (see Figs. 5 and (3,) adapted to engage one of a series of notches 0 formed in the periphery of a disk 0 forming part of the bearing for the corresponding pivot-rod or other device on which the partis hinged, fastened, or pivoted. Now by the operator pulling on the knob N the arm 0 is disengaged from the respective notch 0 to permit the operator to turn the knob so as to swing the plate into an inclined position, and then by releasing the knob N a spring 0' pressing on the pivot N draws the latter, as well as the knob N and the arm 0, inward to engage the free end of the latter with the corresponding notch 0, so as to lock the plate in the desired angular position. The spring 0*, previously mentioned, is coiled on the pivot N and is contained in a casing O fastened to the back of the disk as plainly shown in Fig. 6. One end of the spring 0 rests on the back of the disk 0 while the other or inner end presses on a collar N on the pivot N, so as to force the latter inwardly whenever the operator releases the pressure on the knob N as previously described. It is to be understood that the pivots and knobs of the valves F, registers L, and damper K are constructed and operated similarly to the knob and pivot of the plate N. Now it will be seen that the solid particles of the products of combustion passing up the fines F will pass intothe soot-box ll in which the same aecumulate,while the gaseous products of combustion pass out of the cap I into the outer air above the roof of the building. Now the soot-box, H can be, from time to time, conveniently cleaned so as to remove the soot, it being understood that the soot is prevented from passing down the airshaft F. through the several registers L into the rooms, as the said soot-box is made sufficiently tight to prevent the soot from escapin g.
The removal of the soot-box ll gives access to the fines F for repairing the same, when necessary, or for other purposes.
The fireplace A is preferably provided with a removable ornamental plate forming part of the front of the mantel, and permitting access to the interior of the heater for cleaning, repairs, (to.
It is understood that the form of the lines F is governed altogether by the radiation of the different forms of pipe, and maybe straight, curved, or otherwise without regard to the shape or construction of the air-shaft or chimney. All flue-joints must be screw-joints or some other equally good joint.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination in an open-fireplace heater, with the grate, of a swinging back plate having a pivot N at its lower rear edge jonrnaled adjacent to the rear upper ed go of the grate and having an operating knob or handle exterior to the fireplace and by which the upper free edge of the back plate may be swung toward the open side of the fireplace to direct the products of combustion outwardly and around the free edge of the plate, substantially as shown and described.
2. A fireplace-heater comprising a grate, caps closing the flue thereabove, vertical series of smoke-pipes connecting said caps to heat the air in the flue therebetween, a damper F hinged below the lower ends of one series of smoke-pipes to swing up and close them; said damper being provided with means for operating it exterior to the fireplace, and a removable soot-receptacle suspended from the lower cap within the fireplace and out of the path of said damper and back plate, substantially as described.
An air heater provided with an open fireplace having a hinged back under the control of the operator, friction-rollers on the free end of the said back, and segments on which travel the said friction-rollers, each segment being provided at its lower end with an upturned flange to form an abutment for the said friction-rollers, substantially as shown and described.
4. An air-heater having a hinged back piece or regulating device provided with an operating mechanism, comprising a pivoted rod carrying a knob, an arm secured on the said knob, a notched disk adapted to be engaged by the said arm, and a spring pressing on the said pivot to hold the said arm in. en gagement with one of the notches in the disk, substantially as shown and described.
