y T 0 all -zcLom z't may Concern:

Be it known that FRED E. VHITE and Fnlininncii E. llooinn, citizens of the United States. and residents of Gardner. Massa.- chusetts, haveini'entcd certain new and useful Improvements in Oil-Stoves. of which the following is a specifi ation This invention relates to oil stoves. and the application constitutes a division of an application tiled rby us April 4. 1916. No. 88.888 now ,Patent No. 1,210,522, granted September 1S. 1917.

The invention .is an oil store of the type known as blue fjame. in which kerosene oil isused as a fucl'and is fed from a reservoir through a horizontal pipe line from which project vertical extensions supporting burn ers which are vertically movable to vary the level of the oil therein. the reservoir being;r of the, maintained oil level type. The present application is directed particularly to the, details ot' the mechanism for raising and lowering' the burner bowls and maintainingan oil-tight'connection in the movement.

ln the accornpanyinglr drawing` Figure 1 .shows a partial View of the stove with the supporting and operating means partly in section and partly in elevation.

Fig'. 2 is a view at right angles showing a section taken through the front of the stove.

' Fig'. 3 is a detail of vthe elevating means.

Fig. 4 is a section on line l--l-ot Fig. 1.

Figs. 5. (i and 7 show details of the packing for effecting the oil-tight connection between the. moving parts.

The top otthe stove is made of sheet metal as shown at a, with ordinary gratings a, removably located in theI usual openings in the, stove top. The pipo line of ordinary construction is shown at I. having vertical extensions m to support the burners fw. The combustion chamber is composed of concentric tubes v. perforated. and supported from the burner bowl. which has an initial lighting medium m, the burner bowl being supplied with oil through theI tube y. This tube enters the top of the stand pipe Im, through an oil-tight connection shown especially in Figs. 5, 6 and 7. The pipe y its within the pipe m and a nut z engages the threaded end ot the pipe m, providing a space between the upper end of the pipe and the nut tor an asbestos packing a. ll'e apply the packing by threading 'the stand-pipe lm.. shown in Fig'. o, externally. and reducing its internal diameter as shoe at /1 so as' to make a close lit 'for Vthe time ff clearance being provided beneath the .tt o between the inside ot' the pipe m and the exterior ot the tube y. The packing; in the form of a` round cord ot asbestos is inserted within the nut rv, as shown in Fie'. il. and then the lint is forced down until the ,nacking is closely compressed when it forms a "t" `perfect oil tie'ht joint. a most important threaded end ot' the pipe m. through the Incdium oi a turned down threaded piange c formed by punching r through the bracket and the adjustment ot' the parts may thus be etl'ected. 'llie bracket c has a right angledextension parallelinet the pipe m, Ishown at f Fig. 2. and is bent a second time horizontally as at g with an opening therethrough which encircles the pipe mY and tends to strengthen the connection. The rei-tical extension has ears It Vstruck up out ot the metal of-the part and these ears form guides for a double metal part i which bolted at its upper end to a bracket is se cured to the bowl.

Between the double portions of the part il is inserted a toot-hed rack Z shown in Fig. 23 and this rack is provided with projections m. which extend out. through openings in the. double wall ot' the part i tending?,l hold the rack in place. requiringl no further attaehinj.r means and also serving incid To: tally as stops to limit the upward and down ward movement, of the burner, these stops coming in contact with one of Ythe ears .ity of the, part f. Vertical movement is given the rack through a tlat gear n secured to Btl the e d will an operating lever o and supported irl a long bearing p and 4by the tnrning'bf the Operating handle vertical movemlznt, is given the burner. The stove is provided W1th a front plate g extending lfrom side to side and this plate carries indicating' devices So that the handle Which has a pointer 8 as it is rotated indicates *what action is effected by its movement. The long hearing p is preferably secured in it-,lace by a screw and nut clamping an ex-y tension thereof to the bracket c.

lin, Fig. 4 the combustion chamber, it will be cbserved, is of very simple construction, beingI made of two concentric tubes o with a bottom section 'U' perforated, andan upper section c having a central opening.

-v What We claim is:

l. In an oil. stove, a vertically movable burner, ar oil supply pipe supporting the Same havn ,q a turned in end, and an oiltight connection between the parts comprising a threaded nut fitting over -the turned in end of the standpipefwith a packing Within the nut above the end of the standpipe, substantially as described.

i2. In an oil stove, a standpipe for supplying oil, a vertically movable burner, and means for supporting the burner upon the standpipe comprising a bracket lo extending -laterally lroni the inside of the burner bowl,

a part carryingY a rack depending from said bracket, and an operating handle supported from the standpipe carrying a pinion meshing' with the rack to move the burner, substantially as described.

3. In an oil stove, a Standpipe, a burner supported thereby, a bracket having ears in'its vertical face, a vertically movable double part held by said ears, and a rack carried by said part andhavinzg` projections serving' to retain the rack in place and also as stops to limit the up and down movement of the burner, substantially as described.
