VALVE FOR REGENERATIVE FURNACES.
SPECIFICATION forming part of Letters Patent No. 610,076, dated August 30, 1898. I
Application filed January 26, 1895. Serial No. 536,339. (No model.)
To all whom it may concern.-
Be it known that I, GnoRcE'W. MCCLURE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new.
hot-blast stoves set in position in the blast main and provided with my improvements. Fig. 2 is a sectional plan view, partly in section, on the line II II of Fig. 1.
In the drawings, 2 3 represent the masonry of the blast-main of a hot-blast stove, the sections of which are divided and are faced with metal rings 4 4:, between which the valveseat is interposed.
5 5 are links by which the sections of the main may be tied together. The valve-seat casting, preferably made of phosphor-bronze or other suitable metal, comprises a horizontalannular portion 6, which forms the valveseat proper and is a complete annulus, and a vertical portion or casing 7, which extends along and above the portion 6, around a portion of the circumference of the latter, and has parallel tangentially-projecting legs 8, connected above and below by horizontal webs 9, constituting, with the legs 8, a casing within which the valve may move. The up per edge of the vertical water-cooled portion 7 extends above the level of the top of the valve and abuts against the base of the section of the valve-chamber or fine above it, and the valve-seat projects inwardly beyond said portion 7 to afford a ledge on which the valve slides freely. An outwardly-extendin g prolongation of the casing is constituted by a box or cap 10, having at the end a hole through which the rack on the valve-stem projects.
The annular portion 6 is made'hollow and is divided by a partition 11. An inlet waterpipe 12 enters the same on one side of the partition, and an outlet-pipe 13 is on the other side. Similarly the vertical portion 7 and the parts 8 and 9 are made hollow, communicatin g with one another, and in the portion 7 is a partition 14, on opposite sides of which are an inlet-pipe and an outlet-pipe. Through these pipes constant cooling-streams of water are maintained through all the parts of the casting, and by the use of the partitions the water-coo1ing of the valve-seat and casing is effected in the most thorough manner.
15 is the valve, which slides horizontally within thecasting on the seat portion 6. It has a water-cooled stem 16, which is pivoted to the valve at b and extends through the hole in the cap 10 and is provided with rackteeth 17, meshing with a pinion 18, by rotation of which the valve is moved on its seat. The cap 10 is provided on its upper or lower face with a manhole 19, which permits the stem to be uncoupled easily from the valve, and with lateral manholes 20 to enable the cap to be cleaned.
By the arrangement of the water-cooled passages in the valve'seat casting the valveseat casting and-the valve are preserved much more effectively than in any prior construction known to me, and the construction which I have described affords numerous advantages which will be appreciated by those skilled in the art.
The form and construction of the parts may be varied within the scope of my invention, since What I claim is- 1. The combination, with a furnace-flue, of a water-cooled valve-seat set therein; a sliding valve 5 and a casing interposed between the seat and the flue above, having ver tical water-cooled portions extending above the level of the top of the sliding valve upon which the upper flue is adapted to rest, and. water cooled webs extending horizontally above and below the valve between which the valve may slide; the valve-seat having a hollow water-cooled led ge'proj ecting inwardly beyond the casing, upon which the valve slides; the chambers of the casing and of the posed between said seat and the flue above having vertical water-cooled portions extending above the level of the top of the sliding valve and partially around the circumference of the valve-seat, and having tangentially projecting vertical water cooled legs connected at top and bottom by horizontal Water-cooled webs, between which the valve may slide; the valve-seat having a hollow water cooled ledge projecting inwardly beyond the casing; the upper flue being supported partially by the vertical portions and my hand.
