Another object of the invention is to so mountv the trays and so connect them with the door l of the oven that when the door is open, the

trays will not only be shifted longitudinally of the oven in an outwardly moving direction, but

also have upward-movement imparted to them and thus lift the frame of the trays out of en- 15 gagement with the bottom of the oven and prevent wear upon the frame by scraping engagement with the bottom of the oven.

' It is another object of the invention to so mount the frame of the traysthat during open- 20 ing or closing of the oven door, the frame and Vthe trays carried thereby will be maintained in substantially a' horizontal position andv thus prevent spilling of the contents ofl pans placed upon the trays.

Another object of the invention is the provision of adevice of this character which is.

simple in construction and may be very easily applied to an oven ot a conventional construction.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a sectional view taken vertically through an oven'with the door closed and the trays housed within the oren.

35 Figure 2 is a view similar to Figure 1 show-y ing the door swung outwardly to an open position and the trays moved outwardly with the` door.

Figure 3 is a sectional view taken horizontally through Figure 2 along the linea-r3.

Figure 4 is a sectional view taken along the line 4-4 of Figure 2.

Figure 5 is a fragmentary view illustrating the manner in which end portions of bars or strips are connected to forni an upper corner portion ofthe frame.

FigureA 6 is a perspective view illustrating the manner of connecting the rear corner posts with the upper side bars of the frame.

'Ifhe` stove, which is indicated in general by the numeral I, is of a conventional construction and j-has a baking compartment or oven 2 located over a lower compartment 3 in which burners or heating units of a conventional conl 55 struction are to be mounted. The frame of the (CL B12-174) trays `has a bottom plate l which serves as a lower tray, front and

rear corner posts

5 and 6 and upper side bars 1 upon which the upper tray 8 rests. 'I'he bottom. .plate l is formed of sheet metal and has marginal portions bent to 5 provide depending ilanges 9 along its sides and iront and rear ends. The corner posts' and 6 are formed of angle metal and are disposed vertically at corners oi the bottom plate with their lower ends riveted to the depending side and 10 endilanges of. the bottom plate. At their upper ends, the front corner posts are split and their iront flangesl bent to form rearwardly extending tongues i0 upon which rest the inwardly extending horizontal anges of the side bars l which are also formed of angle metal. Forward ends o! the horizontal ilanges of the side bars are riveted to thetongues I0, as shown at il, while the vertically extending flanges of the side bars are riveted against the inner` faces of the upwardly projecting side flanges of the corner posts, as shown at i2. The rear corner posts 5 are also split from their upper ends and their side anges bent inwardly to form tongues I3 upon which resty rear end portions of the horizontal anges of the side bars. The vertical ilanges ci the side bars project rearward- 1y beyond the horizontal anges thereof and are bent inwardly to form tongues I4 :which bear against the upper end portions oi the rear anges of the rear corner posts. Rivets I5 have been shown as means for rigidly securing rear end portions of the side bars to upper end portions of the rear corner postsA but it is to be understood that welding may be used in place of rivets and also that the forward end portions of the side bars may be secured to upper ends of the corner posts by welding instead oir'by rivets. By forming the side bars 1 and the front and rear corner posts of angle metal and secur- 40 ing front and rear ends of the side bars to the corner posts, as shown in Figures 5 and 6, the side bars will constitute Atracks open at their forward'ends and having abutments at their rear ends. p Therefore, the upper tray or grid 0 may 45 be easily set in place upon the inwardly extending 1horizontal flanges of the tracks or side bars and slid longitudinally into position to rest thereon, as shown in Figures 3 and 4. When it is desired to remove this upper tray or grid, it can be grasped at its front end and drawn forwardly along the horizontal flanges of the side bars and then lifted out of place. It may then be thoroughJy cleaned and returned to the side bars. l If soMdeSired, side -bars corresponding to the side bars 1, and a rear corner bar may be em#- ployed in place of the bottom plate 4 and a removable tray or grid corresponding to the tray 8 set in place thereon.

The'frame and trays are to be mounted for shifting movement as a unit longitudinally of the oven from the housed or retracted position shown in FigureA 1 tothe extended position shown in Figure 2 when the door I8 of the'oven is open. In order to do so, .there have been provided runners I1 which are formed of angle metal and have rear ends of their vertically disposed flanges pivoted to lower ends of metal links Il, the upper ends of which are pivoted to the vertically disposed ilanges of the side bars 1, as shown at Il.

The forward end portions of the vertically disposed flanges of the runners I1 project beyond the horizontal flanges thereof, as shownl in Figures 1 and 2,to provide arms 20, the forward ends of which are pivoted to metal strips 2|. 'I'hese strips 2| are welded or otherwise rmly secured in crossed and transversely extending relation to metal arms 22 which against the inner face of the door in spaced relation to the hinged ends thereof. It will thus be seen that the frame of the device is pivotally connected with rear arms Il and front arms 22 to which the runners l1 are also connected and that when the oven door is swung outwardly and downwardly from the closed position shown in Figure 1 to the open position` shown in Figure 2, the arms 22 will exert uiting and pulling action upon the frame, while the runners will be slid longitudinally. bracketsor arms 22 are pivoted to the brackets 24 carried by the side bars 1 of the frame provides a very good pivotal connection between these parts and permits the front end portion of the frye to be easily lifted and the frame shifted fo ardly out 'of the oven when the door is swung downwardly to the open position. Attention is further called to the fact that as the door is swung outwardly and downwardly towards the open position, the relation of the pivotal connection 25 to the hinges 26 ofthe door will cause the forward end portionsof the runners to be lifted. Therefore, during outward and downward swinging movement of the door, only the rear ends of the runners will rest upon the bottom of the oven and the runners may move very easily from the retracted position of Figure 1 to the extended 'position of Figure 2, The frame is lifted Ibodily from the runners during the outward movement by the swinging movement'of the arms it and the arms or brackets 22 and maintained in substantially horizontal podtion. "Therefore, articles placed in the oven upon the upper tray I l or the lower tray 4 will not be liable to roll on of the same or become spilled due to tilting of a dish. An improved koven tray .and actuating means therefor has been provided which may be very easily applied to an oven of a conventional'construction. It will also be notedthat the device operates very easily as frictional resistance is reduced to a-minimum and that when the oven dooris opened, the frame and trays carried thereby will be shifted outwardly toa position in which articles may be placed upon or removed from the trays`without reaching intothe hot oven.

Having thus described the invention, what is claimedas new is:
