Hoi-BLAST VALVE..
SPECIFICATION forming part of Letters Eatent No. 659,805, dated October 16, 190. Application filed March l, 1900. Serial No. 6,933. (No model.)
To all whom, t may concern.-
Be it known that I, DAVID BAKER, of Chi; cago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Hot-Blast Valves, of which the following is a specification.
This invention has reference to valves designed more particularly for use in connection with blast-furnaces to control the hot blast; and the invention consists of an improved construction of the val-ve, having in view its reversibility on the valve-seat.
The invention consists also in an improved mode of attachment of the valve-stem to the valve, designed to admit of its ready removal without injury and its attachment to the opposite side of the valve.
The invention consists also in the details of construction and combination of parts hereinafter described and claimed.
In the accompanying drawings, Figure l is a vertical sectional elevation of the valve, its stem, and casing. Fig. 2 is a sectional elevation, on an enlarged scale, through the valvebody and the stem, showing how the latter isA detachably connected with the body.
Referring to the drawings, l represents a valvecasing formed with a circular valveseat 2, on which is seated a valve 3, consisting of a hollow body having on its peripheral edge two opposing` valve-surfaces 4 and 5, identical in form and either adapted to rest on the valve-seat in the reverse positions of the valve-body. The valve-body is hollow to admit of the circulation of a cooling medium therethrough and is formed in opposite sides at the centers with threaded openings 6 and 7, either adapted to receive a hollow tubular stem 8 and a plug or stopper 9, the latter being threaded exteriorly to fit the openings and adapted to close one when the valve-stem is tted in the other, so that the valve-body may be reversed when desired. The end of the tubular stem is expanded tightly in a sleeve or bushing l0, which is threaded eXteriorly to iit the openings in the valvebody, which peculiar form of attachment will permit the stem to be quickly and easily removed Without injury `to it, so that it may be readily changed from one side of the valve-body to the opposite side when the valve is to be reversed and so that the stemt when several valves are employed may be changed from one to the other, as is often desired in prac; tice. rPhe tubular stem is extended upward through the top of the casing and surrounds a tubular core ll,in to which a cooling medium from any suitable source may be introduced into the valvebody,whence it passes between the stem and core and out through an opening l2 in the stem, whereby the circulation of the cooling medium is maintained.
By the construction described in the event of wearing or the ill-itting of one of the valvesurfaces the valve-body may be reversed to bring into operative position the opposite surface, which is accomplished by unscrewing the stem and removing the plug, after which the body may be reversed, the stem again screwed in place,and the plug inserted to close the opposite opening. The life of the valve is thus doubled and a close tight t insured at all times.
Having thus described my invention, what I claim isl. In combination with a valve-seat,a valvebody movable to and from the seat at right angles to the plane of the valve-seat and provided on opposite sides with valve-surfaces either adapted to rest on the seat, an operating-stem extending at right angles to the plane of the valve-seat, and means for connecting the stem detachably with either side of the valve-body as desired.
2. In combination with a valve-seat, a hollow valve-body provided on opposite sides with valve-surfaces, either adapted to rest on the valve-seat, and formed in opposite sides with openings, a hollow detachable stem adapted to fit in either opening, means for closing one of said openings when the valvestem is fitted to the other, and means for circulating a cooling medium through the valvebody.
In testimony whereof I hereunto set my hand, this 17th day of February, 1900, in the presence of two attesting witnesses.
DAVID BAKER.
