Fixed `to the inner or rear end" olf the broiler drawer are winged extensions 30 (see 3)y which, respectively, lap by the open sides ofthe Vvreslgxective inner strips. (See Fig. 11:) Each winged-extension v3|lbears a hub `31 'on which turns Va roller 32 located to lie between the `flanges 21- -and Z2-of Eeachinner strip. Fixed to the outer or ifo-re end fot the `side f2llof veach of the inner strips is an extension 34 bearing a hub 35 on which turns 1a roller '3B Aengaging the bottom llaites Il ofgtlie broiler drawer. `@See Figs. 5 and When the vdrawer Ihas been moved full into the broiler compartment, `as shown 'in Fig. 2, its front panel 3V will ihave bearing aga-inst the Iface of the range body and the drawer will be resting `along the fore end port-ions of its 'bot-tom plates 1 di; rec't'lywupon `the rollers 36 borne by the `inner strips, land valongV its rear end portions, throng-h the rollers 132, `upon the bottom fiamges V22, of the inner strips. i As the drawer 'is pulled out the inner strips, Vupon which the draw-er is then resting, will gbe 'telesoopioally withdrawn from the outer strips, the inner strips then riding upon the rollers 23 and the rollers 29 borne by the inner strips then running upon the bottom flanges I9 of the outer strips. During this withdrawal the hubs 28 of the rollers 29 will draw along the slots I6 in the sides l5 of the outer or fixed strips. The telescopic withdrawal of the inner strips, bearing the drawer, will continue until the hubs 28 engage the outer ends of the slots I6 when further withdrawal of the drawer by way of telescopic withdrawal of the inner strips is stopped. Withdrawal of the drawer continues by the draw.- er continuing to run on the rollers 36, borne by the inner strips, while its rollers 32V will first run upon the bottom flanges 22. of the inner strips and later the overbalancing weight of the drawer will cause the rollers 32 to engage andrun upon the top anges 2| of the inner strips.' Complete withdrawal of the drawer is prevented by contact of the rollers 32 borne by the broiler drawer with the rollers 36 borne by the inner strips, the inner strips then being held against furtherI withdrawal. Completewithdrawal of the drawer is also prevented by means later to be referred to.

Located within the drawer are sets of arms 38,

38, and 39, 39, respectively. Each set of arms is connected by a plate 40. This plate is preferably made of sheet metal and the arms are in the nature of flanges turned from the ends of the plate. Each set of arms is pivoted to the sides of the drawer, the pivotal connections comprising a screw 4| on the shank of which is arranged a spacing sleeve 42 arranged between the head of the screw and the side of the drawer and upon which sleeve the arm turns; (See Fig. 9.)' The screwfafter passing through the sleeve and side of the drawer, is secured by a cap nut 43. The arms are pivoted to the sides of the drawer at points adjacentr the bottoms of its sides so that the arms may be turned to assume a downturned position or an upturned raised position. The sets of arms are connected to turn in unison by a plate 44 interposed between the top ends of the respective sets of arms. This plate is provided along its sides with upturned flanges 45 by which the top ends of the respective arms 39 lap on the outside (see Fig. 8) and are secured by fastenings which provide both a pivotal connection between the sets of arms and the plate 44 and bear, also, rollers 46 which extend in part above the respective flanges. Each of these rollers turns upon a hub 4l. This hub is provided with an extension 41 of lesser diameter than the main hub and this extension fits within an opening formed in the flange-45, afterwhich the hub is secured by a screw 48 passed from the inside through the hub and its extension and through an opening in the end of the arm 38 and then secured by a nut 49, a lock washer being preferably interposed between the nut and the side 'of the arm.

Resting upon the rol1ers46 is the broiler pan 50 containing a grid 5|. The broiler pan has the Vgeneral form of the top of the drawer but spaced fromv the sides and ends of the drawer to fit loosely therein. Consequently as the sets of arms are raised or lowered the broiler pan, riding upon the rollers 46, willhave a substantially vertical rise and fall within the drawer.

The weight of the broiler pan and grid will normally be suflicient to maintain the arms in a downturned position.` This is preferably counteracted, to a certain extent at least, by providing the sets of arms 38, 33 each with a spring 52 ywhich tends to raise all the arms.. These 4 springs are arranged upon the hubs 42 with one end bearing against the arms and the other against the drawer, the springs being tensioned to assist in raising the arms as aforesaid.

The sets of arms bearing the broiler pan are raised into an upturned'position elevating the broiler pan within the broiler drawer or the arms allowed to ldrop for lowering the broiler pan, as the drawer is moved in and out,V by a cam 54 which slides upon the bottom 6 of the broiler drawer.

The general form of this cam is shown in Fig.

v rear end 58. Itis provided along its fore end por'- tion with sets of rollers 6U borne by its sides 5l.V

These rollers lie interposed between the sides of the cam and the adjacent side, plates 8 of the broiler drawer. Elevation of these rollers is prevented by plates 6 I secured to the plates 'l of the drawer with lateral extension over the respective rollers. The rollers have extension to have engagement with the bottom of the broiler drawer and roll thereon, thus giving easy slidability to the cam, although the rear end portions of its sides may engage the bottom ofthe drawer, trailing thereon. When theV cam isrmoved back inthe broiler drawer its less elevated rear portion will pass through the opening 9 left below the back of the broiler drawer and between it and the bottom of the drawer, as previously explained. 'Ihe cani may be moved back in the broiler drawer until its rear set of rollers 60 engages xed'stops 62 which are Iixed to the plates 'l of the drawer to lie in theY path of'the rollers'l At about the same time that the rollers engage the stops the surface of the cam will have engaged the bottom edge of the back of the broiler drawer which also acts as a stop'for limiting the rearward movement of the cam. As will presently be explained the cam is held xed when vits surface engages.

the bottom edge of the back;of the broiler drawer and the cam will prevent any undue withdrawal of thedrawer from `out of the broiler compartment and from the respective stops.

Engaging the .cam surface 55 are rollers 63, each borne by a bracket 64 xed to the plate 40 which connects the set of

arms

38, 38. The rollers are held in contact with the cam surface to follow its contour by the weight of the broiler pan, grid borneby it, and material being broled. ,The arrangement is such that when the rollers 63 are engaging the high surface of the cam, as shown in Fig. 3, the arms will beraised to support the broiler panin its uppermost raised position in the broiler drawer, and when the rollersare engaging the lowl surface ofthe cam the arms will assume a downturned position, as shown in Fig. 2, where the arms are shown supporting the broiler pan in its lowermost position in the broiler drawer. Thus thebroiler` pan is raised bythe cam, dependent upon its position in .the broiler drawer and permitting of lowering by gravity, dependent upon the position ofthe cam in the broiler drawer.
