'The .present invention relates'to burners. More particularly the present invention relates to burners applicable kto hot blast stoves and blast furnaces. Inblast furnacey prac'- tice, When the hot blast stove is on gas, the

burner 4is connected. tothe furnace to direct air and gas into said stove, 'a port being. provided for the ingress of said air land, gas. Vhen they hot'blast stove-is oli-blast, said -port is closed by means of a door commonly disposedfuponthe outside of the-,hotxblast stove or its equivalent.` It has been common practice to move the entirek gasand air ydirecting mechanism when saidy door'is to be operated. vTn large installations said gas and air directing mechanism isquite heavy and the job of moving same is an arduous oneg `Ain objecty of the present'invention is: to provide a burner for a stove or the. like Which has the advantage that tlie: connection 4to'or vthe disconnection from said stove maybe readily accomplished. Y

A further object is itoprovide a burnerfapplicable vto stove practice Y which involves the movement of .only relatively light Weight parts vIvlien said burner is bei-ng connected to or disconnected from its stove. L

A further object is'V to provide 'a burner applicable to stove practice which is convenient to operate andnot likely to get out of order. f j i f Further objects Will appear as the description proceeds. v

The numeral 10 indicates a blastfurnace stove, and the numeral'll indicates asa Whole aburner adapted lto cooperate with the stove 10. The stove `1() is provided with the; port 12, bounded by the ivall 13, which iva-111113, may

comprise refractory material disposedwithi'n the'imetallic casing 14.

The'burner 11` includes the conduit 15,

which isprovided with the opening 16, which communicates `With .the casting 17l Said casting v17 is `operatively connected tov `the valve seat 18, which valve seat is connected to Ythe gas conduit 19. :As vvillbe noted from Figure 2, communication is hadl from-thefgas conduit .19', through" the valve seat 18, casting. 17 and opening 16,'tothe cond-uit 15.'V Co,- 1

Means'are provided, for moving the valve 2O selectably to open or closed position,iwhich means Will be referred to further presently.

regions with the trunnions 26-26, adapted to be disposed within the yokes 27-27 upon the two sides of the sleeve 25, which yokes are swingingly mount-ed upon a bracket 28 carried by an extension 29 of the casting 17. The yokes 27-27 are secured to the rotatable shaft 30, which shaft has secured thereto outwardly of the conduitV 15 the lever 31, by means of which said yokes may be manually swung about the aXis of the shaft 30. Swing`- ing movement of the lever 31 will, by reason of the engagement of the yokes 27-27 with the trunnions 2626, result in a reciprocating movement of the sleeve 25. Figure 2 shows two. alternative positions of one of the yokes 27. One of said positions is shown iii lines constituting short dashes, which position is the Vpositionin which the sleeve is held closed. The dash and dot line representation of the yoke 27 represents conditions when the In order to p guide the sleeve member 25 in a right line movement, said sleeve member has rigidly securedfthereto a pair of longitudinally extending -bars `32 32. Mounted upon theV shaft V3() are rollers 33-33, which support said ybars 32-32. Disposed rearwardly of the shaft are a pairof brackets 3a-T34, each'of'which carries spaced rollers :35e-35 adapted to engage the upper and lower edges ofthev bars 32-32. The parts are so disposed relative to one `anothertliat when the sleeve 25 is in its withdrawn position the forward extremities of the bars 32-32 rest upon the ro1lers'33e-33.

way ofthe length of the bars 32-32. `When the sleeve v25 isv in its right-hand position as the parts are shown iii Figures 1 and 2, the rearend portions Vof the bars 32-32 are in position to engage the rollers 35-35` and the mid portionsof said bars 32--32 are in position to rest upon the roll- `ers 33e-33. The sleeve 25 and the casing 14 ,p may, if preferred, have cooperating seats.

The sleeve 25 will be prevented at alltimes -from gettingout of'its proper axial align- Vto thelever 39, which may be weighted by the weight 40. Thelever 39 and the lever 31 *l* `arewpreferably upon Vthe Ysame side of the conduit 15, whereby the operator maycon-V veniently control both of said levers. The

lever 39 and theparfts associated therewith are so weighted thatthe valve 29 will remain in-either its closedfor its fropen position .when the.l lever 39 is correspondingly moved to one At this time theV rollers 35-35 are disposed substantially midside or the other of the vertical plane including the axis of the shaft 38.

` In the operation of the device, the opera tor may control the supply of gas by operating the valve 39, opening the valve 20 by swinging the lever 39 to the left as the parts are viewed in Figures 1 and 2, and closing said valve by swinging the lever 39 to the right as the parts are viewed in said figures. During operation, gas from the gas conduit 19 will mingle with the air delivered by the conduit 21,'forming acombustible mixture entering the port 12.

The relativesupplies of air and may be controlled by any of the well known means upon the market Vfor that purpose. Y When gas and air are being supplied to the hot blast stove, the sleeve 25 will, of course, be in its closed position, as indicated in full lines in Figures 1 and 2. llVhen it is desired to disconnect the burner 11 fromthe hot blast stove 10, the supply of gas and air will be shut ofi and the lever 31vwill be-swung to the left as the parts are viewed in Figures 1 and 2, whereby .the sleeve 25 will be moved away from the blast furnace 10, being guided in a straight line movement by reason of t-lie engagement of the bars 32-32witli the rollers 33-33 and the rollers 35-35. l/Vheii the sleeve 25 is moved tothe left, as shown in dot-ted? lines in Figure 2, ample room will be provided for manipulatingf the door (not shown) for closing the port 12.

Though a preferred embodiment of the .present invention has been described iii detail, many modifications will occur to those skilled iii the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

lVhat is claimed is* 1. In combination, a stove, a conduit for directing gas to said stove and a conduit for directing air to said. stove, one ofszid conduits being in, encircling relationship with the other of said conduits, said conduits stoppiiigshort of said stove, and a sleeve slidable along the outermost off said conduits, said sleeve being adapted to `complete kthe connection-between said outermost conduit and said stove. v f Y 2. In combination, a gas supply conduit7 an air supply .conduit communicating with` said gas supply conduit. one of said conduits being enclosed within the other of-saidcon duits, a valve controlling said supply conduit, a hot blast stove, said conduits being disposed in position to direct gas and air to said hot blast stove but stopping short of said hot'blast stove, a sleeve cooperatively ,associated with said. conduits and adapt-ed to complete the connection of said conduits witlisaid hot blast stove, and manually 0perable means for controlling said gas conduit valve and for controllingthe position of said sleeve, said manually operable means being llO disposed adjacent to one another upon the same side of said conduits.

3. In combination, a hot blast stove, means for directing an' and gas to said Stove, said ineens stopping short of said stove, and a sleeve slideble along said means for conducting a mixture of gas and air delivered by said means to said stove, said sleeve being adapted to complete the connection between said means and said stove.
