FURNACE-BE GULATOR.
Specicatoniof Letters Patent.
Patented Feb. 23, 1909.
Application filed February 4, 1908. Serial No. 414,276.
To all who-'mit may concern:
Be it known that I, FREDERICK D. KEES, a citizen of vthe United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented a new and useful F urnace-Itegulator, of which the following is a specification.l
This invention has reference to improvements in furnace regulators, and it is ldesigned to produce a regulator for the draft openings of a furnace which shall be an imrovement on a furnace regulator patented I y Willum Hager, the patent being numbered 870,028, and bearing date Nov. 5, 1907.
The invention consists essentially in providing the furnace regulator of Hager with certain improvements w creby the ash-pit door may be limited in or restrained from movement while the air inlet valve is at all times under the control of the regulator, and is unrestrained in movement Within the limits of the regulator movement.
As constructed in accordance with the above. mentioned patent the regulator opens the draft ofthe ash-pit door at the same time thatit closes the air valve on the smoke pipe and closes the latter at the same time that it opens the former. The instant the furnace cools off a little the draft is opened and the check closedso that there is always a draft on the fire. It has been found almost impossible to hold a fire in the furnacel over night or to keep the temperature down in mild weather. Thus, the consumption of the'coal is continuous under all conditions of Weather. In the present invention the purpose here is to prevent, when desired, the ash-pit door from opening or to limit the amount of opening thereof while at the same time theair valve in the smoke pipe works automatically. This is found to produce a more even temperature and a smaller consurrvption of coal.
ith the above and other objects in view the invention consists in the second novel dev tails offarrangements and combinations of parts, fullyv described, illustrated in'l the accompanying drawings, and particularly set forthin the claim. 1.-
Inthe accompanyin drawings like characters of reference indicate likeparts in the several views.
Figure 1 is a side view of a furnace equipped with this invention. Fig. 2 is a detail view of a modification of'certain pa'rts of the device.
Referring to the drawing above mennaceis also provided with the -usual pipe 4,
having an air inlet valve 5, which is similar to that provided in ordinary furnaces.v A chain 6 passes over a sector 7 and ltransversely over a pulley fastened to the floor 9 above the furnace by means of a suitable hanger, and thence downward to connect to the valve 5. The sector 7 is provided with a hub having -a short radial arm 8. A hanger 9 carrying a wheel 10 is connected to the sector 7 by 8, 6, 9, and 11 and provided with a wickered arm 12. l
The furnace 1 is provided with a. dome 13 connected' with the wheel by means of a rod 14. Attached to a suitable portion of the furnace and to the door casting is a latch 15 which latch lmay be in the form of a bar having a number of litt-le holes therealong as shown in Fig. 1 or may be a simple hook as indicated in Fig. 2. Attached to the lower end of that portion of the chain which passes downward from the ,sector 7 is a spring 16 preferably of: spiral form. In the is attached to the lower end on said spring 'a wire 17 connected with the valve 3. The
Referring again to Fig. 1 the openings the latch 15 are so arranged that when the wire hook 18 is inserted in the lowermost opening, the spring will be drawn downto such a position that the valve 3 will at all .times remain closed. By positioning the It is to be observed that,v Whether the valve 3 be arranged to remain entirely shut or Whether it be allowed `v`a .limitedv amount of opening movement, the valve 5 can at all times be actuated by the movement of the sector 7. It is thus seen that it is not only possible to control both the valve 3 and `the airfvalve 5 ,by the regulator but it is possible S0 to adjust the parte of the device that the air valve 5 may be Amore fully under control of the regulator than the ashpit doorvalve 3. It Will be evident, however5 that the operation of this device. When once adjusted,
is entirely automatic. f
Having thus described the invention, what is claimed, is
In a furnace, a dome capableof the ex ash-pit, a smoke pipe, an air valve for the 20 smoke pipe, a chain connected to said air valve, means connected to the dome ar' ranged to move said chain, a spring carried. on said chain, means to connect said spring to the ash-pit draft valve, and co-acting 25 means on said furnace and spring to 'limit the upward movement of the spring.
In testimony that I claim the foregoing as my own, Ia have hereto affixed my signature in the presence of two Witnesses.
