COOKER.

To all whom itmay concern.'

Be it known that I, JOHN E. CHAMnnns,

-a citizen of the United States, residing at Shelbyville, .in 'the eountyof Shelby and State of Indiana, have invented certain new and useful Improvements in Cookers, ot'` and which is so constructed that it .may be lused either as an ordinary gas stove or the gas burner may be utilized to merely 'turnish an initial heat and the device subsequently used as a tireless cooker.

The present invention relates more particularly to the burners ordinarily positioned' at t-he top oi' the stoves and one of the primary objects of the invention is the j provision in connection with such a burner of a hood which may be so positioned as to .constitute together with the top of the stove an airtight heat insulated chamber within which the burner is positioned.

A further object of the invention is the provision oi' improved means for supporting the hood so thatit vmay be adjusted to any desired position relative to the burner and may be swung out o' the way when it is not desired to use the same.

A further object of the invention is the provision of means for clamping th-e hood irmly against the top of the stove so as to vform an air tight joint therebetween.

Other objects of the invention'will be apparent from the detailed description hereinafter when read in connection with the aecompanying drawings forming a part hereof, vwherein a convenient embodiment of the invention is illustrated and wherein like nii-- mer-als of reference refer to similar parts in the several views.`

In the drawings, Figure l is a fragmentary side elevation `of the improved cooker., partly in section the hood being shown in its lowered position. Fig. 2 is a fragmeir tary rear elevation of the cooker, Fig. 3 is a fragmentary top pla-n view, `parts being broken away, and Figs. 4, 5 and 6 ,are detail views. Y l

Referring new more particularly to the drawings A designates the body of the stove which is provided .with a suitable oven therein, which maybe of any4 convenient con- Specification of Letters Patent.

struction, as it forms no part of the present invention. The body of the stove is formed throughout with double walls, which may be of sheet metal between which is positioned a packing ot' any suitable insulated material. The upper edges ofthe outer Walls of the stove body areconnected by a plu. rality of transverse steel angle-bars a, the downwardly extending flanges of which are embedded in the packing in the stove body. Supported upon the 'angle-.bars a is a plate of asbestos board, or other suitable heat insulated material, the outer surface of which is covered by a layer of thin sheet metal which constitutes the top of the stove. F rm this construction it'will be seen that a top is provided which has all of the advantages of a metallic top and which will at the same time absorb a comparatively small amount of heat.

B designates a gas burner which may be et any well known type and is supported upon the top oi the stove by legs b depending therefrom, which serve. to hold the burner slightly away 'from the upper surface of the stove. The body of said burner has a threaded connection with the upper end of a gas supply pipel which projects through the top ol the stove, the body ofv said supply pipe .heilig embedded in the packing at the top of the stove and projecting` through one side thereofto permit its connection with a suitable feed pipe. To prevent twisting of the bui'ncr around the supply pipe, one of the legs thereof is made in the 'form of two separated pins between which is adapted to beprojected a bolt 1'/ which is slidably lmounted in any suitable bearing upon the stove top. lVhen it is desired to detach the burner for any reason, this can be readily accomplished by retracting the bolt and unscrewing the burner from the supply pipe.

C designates a pot or kettle rest which is positioned just above and 4around themexterior of the burner.and. is maintained in such position by legs c which depend therefrom and engage the top of the steve. The kettle rest C is prevented from shifting around on the top otl the stove by prtu'iding the upper portion thereof with'a plurality of depending projections c which lit in recesses formed in the periphery o't' the burner.

l) designates a hood which is open at its bottom only and of a size to incluse the.

burner and kettle rest when positioned thereover. The hood 1s formed of an inner and outer wall conveniently of sheet metal, be-

tween which is secured a packing of heat insulated material, so that when the saine, is positioned over the burner with the bottom thereof in-contact with the top of the stove,

amairtight heat insulated chamber is formed within which the burner is positioned. The top of the hood D is provided centrally thereofwith an eye d which is adapted to detachably engage the hooked end of a bracket E, the other end' of which is pivot-v aily mounted upon a suitable support so that the' hood may be swung out of the way when not. in use. In the form of the invention illustrated in the accompanying drawings,

the means employed for supporting the hood so that it may be readily raised and lowered and swung` into and out of position cornprises a'casting in t-he form of a transversely curved plate, which is secured in any suitable manner to the back of the stove and is provided in the front thereof with a longitudinally arranged slot f and inthe upper and lower portions thereof with vertically alined oenings in which is slidably mounted an e ongated vertically disposed rod G.

Secured to the rod G and lying within the slot f in the 'plate F is a collar g which is provided with lateral projections-g which voverlie the front of the plate'F and serve to prevent rotation of the rod Gr. Rigidly secured to the rod G adjacent ,the topthereof are two spaced collars between which' is confined the inner' end of the bracket E heretofore referred to,.s aid bracket loosely encirclinor the rod G so that it ma readilv be Y, c u

swung thereon. The collar immediately below the,bracket Eis provided with an upward projection g2, which is so positioned respectively to the collar g secured on the.

that when the bracket E is swung a sufficient extent to contact therewith, the hood will be positioned directly over t-he burner. Any suitable means may be utilized to raise and lower the rod G and the hood carried thereby and to hold the same in various positions of adjustment. In the present embodiment ofthe invention a pulley h is secured to the upper end of the plate F and a cable passes over said pulley and has its ends connected rod G and to a-weight H. The weight H is sufficiently heavy to hold the rod G and the operation of the burner.

be extinguished and the hood lowered until it is brought' into contact with the to ofthe stove, thereby forming an airtight insulated compartment in which the cooking wilhbevcontinued, in a manner well understood.

lVhile the weight H will serve to hold the hood in any position to whichit-may be adjusted, it may be -found desirable to provide means for clamping the hood tightly against the top of t-he stove toprevent any possib'lity of air passing .under the lower edge thereof and in the drawings means are shown for accomplishing this purpose. The upper portion ofthe plate F is formed with an inwardly extending hook F. Secured to the shaft G below the hook F is a collar I and rotatably supported upon the shaft Gr and resting upon the collar I is a lever K which is provided with a cam surface 7c which extends partially aroundthe pivotal portion thereof. Depending from the lever K is a lug la which isadapted to coperate with suitable stops carried vby vthe collar I. Vertical movement of the lever K on the shaft G is prevented by means of 'a pin which is secured in said rod directly abovethe lever. The arrangement of the stops is such that when the lever is moved to its extreme position in one direction, the cam surface lo will be moved out from under the hook F and the hood may then be adjusted to anydesired position. lVith the lever in this position and the hood lowered, if `the lever is shifted, the cam surface ,7c will be brought into engagement with the underside of the hook F and the lower edge of the hood D will be forced tightly, into en agement with the top of the stove so as to orInl an airtight joint therewith. The thickness of the cam surface 7c is such that if such cam surface is permitted to rest on the top of the hook' F, the lower edge of the hood will be held a sutcient distance from the top of the stove to permit the proper operation of the burner and at the saine time to retain and absorb practically all ofthe heat that is generated.

lVhile a convenient embodiment of the invent-ion is illustrated in the accompanying drawings, it will be understood that many changes may be madel to the form and c'onstruction therein shown Without in any way departing from the spirit and scope of the invention.
