UNITED STATES PATENT QEEIoEo JOHN HABTMAN, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN AUTOMATIC VALVES FOR BLAST-FUR-NACES.
Specification forming part of Letters Patent No. 154,390, dated August 25, 1874; application filed May 15, 1874.
vandv curved or inclined inlet and outlet pipes.
Figure l is a side view. Fig. 2 `is a vertical longitudinal elevation. Fig. 3 is a top View.
A is the valve-body; B, the valve-chamber C D, the inlet and outlet pipes, and E thevalve-cap. The chamber B must be of a capacity to freely pass the blast. The inlet and outlet pipes O D are curved or inclined to and from the chamber B, to give the proper direc- F is a double-face valve in the chamber B. Its bottom face, a, seats on the lower valve-seat, b. Its upper face, a', seats against the upper valve-seat b. To. facilitate arranging the valve in place, and to enable it to be readily repaired and the valveseats reached, the chamber B is provided with a movable ring `or open cap, E, which can be easily taken off and the chamber B opened without first separating the valve' body from the blast-pipe. The center of turning, c, of the valve is shown partly in the ktop of the chamber, and partly in the cap. The upper valve-seat, b', is in this instance on the bottom of the ring or cap E. The gas-escape opening H is formed by the ring E, and an the blast from escaping. When the blast is` thrown o' the valve drops on its seat b, which closes the opening of the blast-pipe and opens the gas-escape H. The curvature of the outlet or discharge pipe D from the valve-chamber to the furnace prevents the backing gas from getting beneath the valve F, which would keep it from closing on its lower seat and prevent the gas-escape H from being opened.
In the operation of a blast-furnace experience has demonstrated that when the blast is thrown off the gas from the furnace is liable to accumulate in the blast-pipe, in the hotblast, or in the air-receiver. By igniting and exploding it causes the most serious and destructive results. The valve F, when the blast is thrown o", closes Aall communication between the blast-pipe and the furnace, and escapes the accumulated gas through the gasescape H.
I claim as my invention- 1. An automatic double-face valve, F, in combination with a valve-chamber, B, having' an upper and a lower valve-seat, for the purpose shown and described.
2. The combinationof a double-seat valvechamber, B, an open cap orring, E, a doubleface automatic Valve, F, and curved or inclined inlet andV outlet pipes C D, for the purpose shown and described.
In testimony whereof I hereunto sign my name in presence of two subscribin g witnesses.
JOHN M. HARTMAN.
