My invention relates to reversing valves, that is, to valves for Vreversingtheiflow of gaseous fluid through a system',
My invention is primarily adapted. for use of producer-gas in conjunction with open- Y hearth furnaces, wherein the gas is, directed through the lire-room (hearth) rst in one direction and thenin another, or the gas is directed alternately through a pair of heating chambers. However, my invention is not to be limited to such specific use but may be adapted for other purposesrwherein it is y desired that the intake and exhaustl gases may be controlled and reversed by al single valve. While the invention may be used for various purposes, l have illustrated and will describe the same as used in conjunction with a reversing blast furnace and particularly wherein a. fuel gas is employed for the blast instead of air only.
The object of' my invention is to provide an improved valve ofthe class mentioned wherein the blast gas vmay be directed through the system first in one direction and then inanother and'wherein the exhaust gas may be directed from either of two exhaust channels to a single flue or chimney. A yfurther object of my invention is to provide a device as mentioned so `constructed thatk the incoming fluid Ygas will be' automaticallyV shut olil during thek reversing operation. A further object ofi-my invention is to provide al device as mentioned which shall vbe of comparatively simple construction and easyto operate and one which will not readlly get out of order. Other objects will appear hereT inafter.
With these objects in view my invention consists generally in upper and lower casing elements and a bell arranged between the same with water sealed joints between the bell and the upper and lower ,casing eleA ments., conduits leading from the lower' casing element and partitions in the bell maintaining a separation between the fuel and exhaust gases and for directing'said gases to the desired channels. My invention further consists in a device as mentioned'in combination with meansfor. raising and lowering the bell and for turning theJl same af,- ter elevation. My invention further consists in a device as mentioned of such constrnction as to automatically shut off the flow of fuel gas to the bellwhen the latter is raised for turning, and reversing the iow of gases. My invention further consists in various de.-
tails. of constructionv andu arrangements of parts, all as lwill be fullyf described herein@ 1 after and., particularly! pointed '011.6' inf the Claimsstood by. reference'. t0, the accompanying drawings' forming a VPalit Of this Specification'.

by threera'dial/Achannels 4, 5 and 6, forming openlngs or portsv 7, 8 and 9 in the bottom of'l the device, which communicate with ducts or 'conduits 10, v11 and 12,1 eading re:
spectively to a chimney 18, and to heating chambers 14 vand 15, as indicated in Figs. 2 and 6. The chambers 14 and 1 5 arev 'connected tothe blast furnace' 16 by blast "ducts 17 and 18 and also by exhaust gas ducts 19 and 2Q. `The mouths of these ducts 1 7, 18,
19 and 20,7`where`they enterl vthe chambers n 14 and 15 arecontrolled by suitableA dampers 21 and 22 so that the blast duct-of one chamber is open when `the exhaust to the other is open and vice versa. e Y
The top element of the casing comprises a gas chamber formed of innerandute'r con centric cylindrical walls 23 and 24 `respecconnected. at their. upper ends by an annular plate .25y constituting; the ltop` of the chamber.' This is supported in anysuitable way, as by a frame-work'26, which is illustrated diagrammatically only i-n- Fig. 1Q 27 indicates the gas inlet connected with any suitable source of supply. Between the upper and'y lower casing elements is a bell :28
comprising inner and' 7onter cylindrical Vrest within theanriular` channels 2 'and 3 of the bottom elements, which channels, to gether with the radial channels 4, 5 and 6, are filled with water to form a gas seal. The top of the bell 28 is provided with in ner and outer concentric channels 32 and 33 respectively, which receive the lower edges of the walls 23 and 24 of the top casing element or gas chamber. rIhese channels are filledv with water to form a seal between the gas* chamber and the bell. Arranged within the bell 28 are radially disposed vertical partitions 34, the lower edges of which terminate short of the bottom of the walls 29' y and 30, but normally extend'into the radial channels 4, 5 and 6, dividing the bell into a blastgas compartment 35 and awaste gas compartment 36. r1`hese partitions are pref-r erably double walled as illustrated so as to containl water for cooling the same. rlhe top of the bell 28 is provided with a gas inlet port 37, about which is arranged a short vertically extending pipe 38. The length of the pipe 38 is such that its upper end will closely Contact the top 25 of the gas chamber when the bell is raisedsuiliciently to permit the lower edges of the partitions 34 to pass overthe walls of the channels 4, 5 and 6 for a purpose hereinafter described.
A. fixed shaft 39 is provided which constitutes a guide for the bell 28, a pair of bearings 40 being fiXedly arranged within the cylindrical element 29 of the bell. Fixed to the upper bearing member 40 is an upwardly extending sleeve 41 upon which is formed an annular flange 42. 43 indicates a sleeve arranged about the sleeve 41 and provided with racks 44, meshing with pinions 45. The sleeve 41 is rotatable within the sleeve 43, whereas the latter is prefer ably non-rotatable. The upper end of the ysleeve 43 is provided with a flange 46 between Vwhich and the iiange 42 are ballbearings 47. t isl obvious that by turning the pinions 45, the bell 28 may be raised or lowered as desired. rlihe sleeve 41 Aextends above the ange 42 and slidably mounted upon the upper end thereof is a pinion 48 meshing with a gear 49 adapted to be driven in any suitable manner. By means of the pinion and gear 48 and 49, the bell may be rotated. The bell isCOunterweighted as shown to facilitate the operation of the device. 25 indicates the counterweights. which may be connectedy to the bell in any desired manner.
The operation of the device is as follows: The bell 28 normally rests in a position indicated Iin Fig. 1 with the lower edges of its walls 29 and 30 resting in the bottoms of the channels 2 and 3 and the lower edges of the partitions 34 submerged in the water of the radial channels as illustrated.A Fluid gas under pressure is passed through 27 to the gas chamber from which it passes As illustrated in the drawings,
perature, and passes trough the duct 12, and
the Vport l9, to chamber 36 of the bell, and out through the port 7 to the chimney duct 10. After the chamber 15 is sufficiently y heated, the bell 28 is raised by means of the mechanism above described and then turned approximately l2()O until its walls 34 are above the channels 5 and 6, and then lowered. lt will be noted that this will reverse the flow of gas 'through the heating chambers and furnace, as the blast gas will now pass through the port 9 to the duct 12, thence through the chamber 15, where the gas is heated andI then through the blast duct 18 to the furnace 16. lt is to be understood that when the bell isV shifted the dampers 21 and 22 are also operated to close the ducts which were formerly open and to open those formerly closed. rllhe waste gas passes out through the duct 19 to the heating chamber 14, which it heats to a high temperature and then passes out through the duct 11 to the port 8 into the chamber 36 of the bell and through the port 7`to the chimney ductlO. `When the bell 28 is raised the end of the pipe 38 engages the top25 of the gas chamber and automatically cuts ofl' the flow of gas to the bell while the latter is being turned. TWhen the chamber 14 is suciently heated, the valve is again reversed, as vare also the dampers 21 and 22, and the operation repeated. f
