Carrier portions 84 also carry 50 stop pins 59 positionedabove hinge pins 55. Clo-y These means comprise horizontally projecting strips 85, suitably secured to the outer vertical faces’of side rails in adjacent the rearward por tions thereof, and positioned to lie within the channels of ?xed guide members ‘I5, and to have a small clearance in normal position with respect to the'vertical portions thereof. _ I - Provision is made to limit the withdrawal of frame 2| under normal operation, but to provide I sure hinge plates 55 have integrally formed latch _ for complete separation ‘and removal of the parts portions 60 which are ‘shaped and positioned when desired. For this Purpose, stops II are pro r to cooperate with stop pins 59 to hold closure vided on Side rails III of frame 2|. As shown, . member 24 inyertical position. The'elongation these stops project laterally from the ‘side rails, I 55 of slots 51 allows the closure to be raised slight 4 and overlie the tops of ?xed guide members ‘It. ly so that'latch portions 60 will clear stop pins 59, allowing the closure to be released and swung to horizontal position. ‘In open position, in tegrally formed stop portions 6| on hinge plates so 50 engage stop pins 59, thus maintaining thev closure 24 in open horizontal position. A.suit able handle is provided on closure 24 for the. con venient performancepf these operations, and also for use in moving the entire movable broiler Cooperating with stops 88 are dogs 8}, pivotally 5‘ mounted at .9 on the outer vertical portions of ?xed side brackets ‘Ii, lying in the path of stops II, and determining the normal outer. limit of movement. ‘When it is desired to completely separate the parts, dogs 88 aremanually lifted about their pivots to a position where stops It can pass clear of them.‘ .

These , detent means are mounted in the rear of cooking compartment II, and are positioned to cooperate vwith movable rollers 8| when. the parts are in operative position and include detent wheels 90 10 mounted for rotation upon arms 9|. Arms 9| are pivoted at their rearward ends .to brackets 92 ?xed to rear wall l3, the arms 9| projecting said liner to said frame for movement therewith and for ready detachment therefrom, a food sup port member, and means on said 'liner for sup porting said food support member at a desired elevation. , A ' 2. A stove of the character described compris ing a cooking compartment, a frame mounted for movement into an operative position‘ in said com partment, and for movement out of said compart ment to an inoperative position, a liner separate 10 from said frame, means connecting said liner to said frame for movement therewith and for ready detachment therefrom, and a closure for forwardly to movably position detent wheels 90 said opening carried by said frame and adapted. in the path of movable wheels 8|. The ‘forward ‘to close said compartment when said frame is 15, 15 ends of arms 3| are downwardly urged by springs moved into operative position within said com 93, the opposite ends Sof which are secured in holes in brackets 92.

Apparatusof the character described com— 30 on frame 2|, and thus releasably retains the frame prising a cooking compartment, a frame mounted in inner position. In operation of the stove, there is seldom any for movement into and out of said compartment, occasion to remove the broiler frame 2| from the cooking compartment ll. During broiiing, however, there is likely to take place a suf?cient amount of spattering so that frequent cleaning of ‘the broiler parts is necessary. The broiler liner 22, built inaccordance with the present invention, can be readily removed for such clean 40 ing, and it is also to be noted that broiler liner 22 ‘affords protection to the withdrawal mechanism, so that these parts seldom require attention. To remove liner 22, the frame 2| is withdrawn to its outer position, and closure 24 is swung about its hinges to open position. Then a lifting motion, applied as to the forward ends of side walls 44, will separate pins 49 from notches 35. During such lifting, the liner pivots about side supports 50, resting on the tops of frames 30, and rear support 52 moves downwardly out of contact .50 with rear cross piece 32. After the forward end ‘ has been elevated sufficiently to clear the forward parts of the frame, the liner may be pulled for ,wardly a short distance and-then lifted com 55 pletely free of the frame structure. To replace the liner, the procedure is reversed, and the sup ports are so arranged that the liner is guided easily and quickly to proper operative position. It will be noted that in the embodiment illus trated, the proportioning of liner 22 and its as ‘ sociated parts is such that it cannot be lifted out _ of operative position unless closure 24 is first a closure member for said compartment hingedly mounted on said frame and movable to an open position, a liner having an open end,'means for mounting said liner on said frame with its open end adjacent said closure member for movement " with said frame, said mounting means providing for removal of said liner from said frame when said closure member is moved to its open position on the frame, a food support member, and means on said liner for carrying said food support mem berand providing for removal thereof from said liner when said closure is moved to its open posi tion.
