GAS-VALVE FOR HOT-BLAST STOVES.
SPECIFICATION forming part of Letters Patent No. 439,926, dated November 4, 1890.
Application filed January 6,1890. Serial No. 336,015. (No model.)
To all whom it may concern.-
Be it known that I, BENJAMIN BEISEL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Gas-Valves for Hot- Blast Stoves, of which the following is a specification.
One object of my invention is to so construct a gas-valve section of a hot-blast stove that when the valve is closed the section can be entirely disconnected from the stove, thus preventing the rapid destruction of the valve and its connecting-fines.
A further object of my invention is to so combine the valve with the section that the valve will be automatically closed when the section is disconnected from the stove, as fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a sectional view of sufficient of a hot-blast stove with the gas-valve open, so that gas may pass from the flue into the hot blast stove. Fig. 2 is a sectional view showing the valve closed and the section disconnected from the stove. Fig. 3 is a plan view of Fig. 1. Fig. 4 is a view of the trunnions, showing the adjustable bearings, and Fig. 5 is a view of a modification.
A is the hot-blast stove.
B is the gas-main having a flue b, communicating with the inlet-opening a in the blaststove through the valve-section D. The valvesection is pivoted, as shown. Its trunnions d d are mounted in suitable boxes 0 in the standards e of the base-plate E. The boxes can be moved either transversely or vertically by means of set-screws 0', so that the valve can be fitted to its seat.
F is a ring surrounding the opening a in the stove and havinga beveled mouth adapted to fit the inclined portion f of the valve D, forming a ball-joint.
The base E has an orifice b and has a seat g turned true from the pivot-point of the valve, and adapted to this seat is the base D of the valve having a segmental projection h, which when the valve is tilted, as shown in Fig. 2, closes the gas-flue.
In the base E is a sliding damper H, provided with a suitable handle. By moving this damper in or out the flow of gas can be regulated.
When the valve is tilted, as shown in Fig. 2, a cap or cover plate I, pivoted at tto the ring F, is placed over the opening in the ring, and a clamp-bar .I is swung into position in front of the plate and secured. A man-hole is formed in the rear of the valve-section, and is closed by a cover K. It will be seen that by having the trunnions of the section D ad- 3' ustable both transversely and verticallyI can at all times have a gas-tight joint both at the junction of the valve with the gas-flue and with the stove.
The operation is as follows: \Vhen the valve is in the position shown in Fig. 1, gas is admitted to the stove from the gas-flue, the flow being regulated by the damper H. If at any time it is wished to cut off the flow of gas the valve D is simply tilted to the position shown in Fig. 2, the valve being so proportioned that it will be balanced in this position, or in some cases weights may be used to cause the valve to remain in the open position, and also catches may be used, if necessary, to hold the valve in the position shown in Fig. 1. When the valve is in the open position, the section h closes the gas-outlet, and the cap or cover I is swung around to close the gas-inlet in the stove. By this means the hot air in the stove will not affect the communicating pipe and valve, as the valve is independent of and disconnected froin the stove. Byv simply removing the cap I and turning the valve on its pivot, as shown in Fig. 1, communication can again be established between the gas-flue and the stove.
In some instances the valve may be made independent of the section D, as shown in Fig.5, the valve being first closed, the section then tilted, and the cover-plate applied; but I prefer, where permissible, to use the construction shown in Figs. 1, 2, and 3.
I claim as my invention- 1. The combination of a hot-blast stove, a gas-inlet therefor, the gas-main and cut-oft valve, a horizontallypivoted flue section forming a communication between the gasmain and the stove, trunnions on the side of said flue section, and bearings therefor,
K i i whereby the section can be swung clear of the gas-main and stove, substantially as set forth.
2. The combination of the hot-blast stove, the gas-main, a pivoted flue-section forming communication between the main and the stove, and a base-plate havingan openin gforming a continuation of the gas-main and having a seat on the radius of the circle described from the pivot-point of the flue-section, said fluesection having contact-surfaces bearing on the said seat, and a surface adapted to a seat on the hot-blast stove, substantially as de scribed.
3. The combination of a hot-blast stove, the gas-main, abase-plate having bearings, blocks mounted in said bearings adjustable both transversely and vertically, and a flue-section having trunnions adapted to said blocks, said
