D. Roper Corporation, Rockford, Ill., a corporation of 'Illinois 19 Claims.

My'invention relates to an improvedv door for broiler drawers in cooking ranges.

Porcelain. enamelled fronts on cooking ranges are, in accordance with recent trends in design, made up of oven ldoors and utility drawers and other panels, allwith their fronts substantially flush with one another and with their edges in closely spaced' relation.- It has often been noticed how the lower edge portions of oven doors Yori-franges Aof such design become s'cu'ed and chipped where the clearance is not quite sufcientfor the doons to open without scraping on the upper edge portions of whatever panels are immediately beneath. The doors on broiler drawers presented a still greater problem because ofthe way they are, of necessity, hinged on the drawersto swing down` to a position with the -inner surface on a level with the bottom of the drawer. As a result unless the housewife took [special precautions to pull the drawer out part way beforemswinging. the door down, the lower edge of thefdoor rode more or less solidly on. the upper edge vof the panel beneath, with resulting strong likelihood of damageto both contacting parts. The door alsohad to be closed before the drawer was pushed in or even worse damage was apt to result, especially if the drawer was movedin with any appreciable speed. It is, therefore,the principal object of my invention to' provide a door for a broiler drawer which is equippedwith means for positively spacing the door and drawer front outwardly relative to the range beforethe door can be swung down, the said meansY functioning to protect the door and adjacent parts of the range front alike inthe opening andclosing of the door.

The broiler drawer in accordance with my invention has the door hinged thereon, and the door is oper-atively connected by a link with one end ofa kick-out plate vpivoted intermediate its ends 'to the side of the drawer and having a lateral projectionA on its other end slidably engaging the front of the range frame alongside the 'broiler `oven compartment, whereby as the door is swung down the kick-out plate is turned and causes the drawer to be moved outwardlyfar enough for the door to have its lower edge clear the front of ,the range'.` The kick-out plate also has another lateral projection intermediate its ends and in radially spaced relation to the pivot which is arranged to engage a stop on the side of the drawer to limit turning of the plate and accordingly limit outward swinging movement of the door so as to support the same in a substantially horizontal position extending outwardly from the drawer.

In the drawings- Figure 1 is a perspective view ofV a cooking range showing the broiler drawer with its door in the open position so as to illustrate the action of the kick-out plates;

Fig. 2 is a vertical section onV the line 2--2 of Fig. 1, but showing the door closed;

Figs. 3 and 4 are diagrammatic views illustrating the kick-out operation by showing the door indifferent positions in the process of being opened;

Fig. 5 is a vertical sectional view on the line 2--2 of Fig. 1, similarly as Fig, 2, but showing the door fully open and the drawer moved part way out;

Fig. 6 is a horizontal section'on the line 6-5 of Fig. 5, and Y Fig. '7 is a horizontal section on the line l-l of Fig. 2.

The same reference numerals are applied to corresponding parts in these drawings;

AThe cooking range 8 contains a broiler cornpartrnent 9, access into which is afforded by opening a door Il. 4The door II is of hollow sheet metal construction comprising a front panel I2 in spaced relation to an inner panel I3 but connected therewith by telescoping its marginal ange I4 over a corresponding flange on the panel I3, lugs I5 on the one flange being en- .tered in slotsIG in the other, asv shown. The door handle IIa (Fig. l) is suitably mounted on studs, the supports for which are between the panels and serve aas additional means for securing the same together, as disclosed in copending applications of Grover F. Whitehead, Harold H. Ring and John F. Hennessy, Serial Nos 307,215, filed December 2, 1939, and 348,126, filed July 29, 1940, respectively. The broiler compartment 9 contains an open front drawer n9a having opposed side walls I1 and I8 interconnected by a bottom wall I9, the side walls having integral horizontal ribs 2! thereon for the support of a broiler pan 2| at any one of a plurality of levels. The pan 2l contains a removable grill 22. The front end of the drawer is reinforced by a U- shaped metal band 2lil which extends beneath the front edge of the bottom wall I9 and upwardly along the front edge of both the side walls Il and I8. The drawer 9a and broiler `compartment 9 are provided with suitable intertting drawerguides (not shown) in order that the drawer may be veasily moved outwardly and inwardly. The indicia at 24 in Fig. 1 serves to designate different levelsof the setting of the pan ZI in the broiling of different foods.

Sheet metal brackets 25 have attaching ears 26 bent therefrom in opposite directions. These vbrackets are spaced inwardly from the side and.

bottom edgesof thedoor II andare secured to the inner door panel I3 by screws 2l. Projecting lears 28 on the brackets 25 are pivotally secured to the reenforcement band 23 on the drawer 9a by rivets 29, so' that the door II is hinged to the drawer 9a and may be swung upwardly and downwardly from the open and closed positions, thereby serving as a front wall for the drawer 9a and as a closure for the broiler compartment 9.

Links 3| are pivotally secured at one end to struck out ear portions 32 of the brackets 25 by rivets 33 while the opposite ends are pivotally connected to one end of kick-out plates or levers 34 by rivets 35. The levers 34 are each pivotally mounted by a struck-in intermediate portion 35 on the band 23 by a bolt 3B at a point above the rivet 29. This pivotal mounting of the levers 34 spaces all but the struck-in portions 35 thereof from the band 23, thereby reducing friction therebetween in the movements of the levers 34. For rigidity, the levers 34 have outwardly bumped, reinforcement ribs 31 extending longitudinally thereof. Outwardly projecting knobs 33 are mounted on struck-out portions 39 on the free ends of levers 34. These knobs are arranged to slidably engage vertical side rails 4| on the front frame of the range on opposite sides of the broiler compartment 9 so that when the door is opened and the levers 34 are turned, the knobs 38 bearing against the posts 4| cause the drawer 9a to be moved automatically outwardly in the proper timed relation with the opening of the door so that the lower edge portion I4 of the door will not ride on the upper edge portion 42 of the range front panel 43 therebeneath.

Figs. 2 to 5 show the relationship between the bottom edge I4 of the door and the upper edge 42 of an adjacent panel 43 at the various stages of opening. Incorporating the kick-out 3 feature through which the drawer 9a is automatically moved outwardly as the door is opened permits the desired close spacing between the door and the adjacent panel 43, as shown in Fig. 2, while rubbing and scraping between these two parts is avoided when the door 4 is opened, as is evident from Figs. 3 to 5. Obviously, if the drawer 9a is pulled outwardly without opening the door |,'the necessary clearance between the door edge |4 and panel edge 42 will be maintained. Furthermore, if the drawer 9a is pushed in from a pulled out position while the door is still open, the knobs 38 will strike the rails 4| and prevent contact of the edge |4 of the door with the panel 43, thus avoiding any possibility of damage to the range by reason of careless operation of the broiler drawer.

An inwardly projecting knob 44 is provided on each of the levers 34, intermediate the ends thereof and in radially spaced relation to the pivot 36, for engagement with the rear edges of band 23 when the door reaches horizontal position, as shown in Figs. 5 and 6, the levers 34 being thus held against further clockwise movement to support the door in the open position.

The door is held releasably in closed position by detent means comprising rollers 45 rotatably mounted on pins 46 carried on the free ends of leaf springs 41 that are fastened to the brackets 25 by rivets 48. Openings 49 are provided in the brackets 25 for the projection therethrough of the rollers 45 to enter other openings 5| in the band 23 when the door is in the closed position. As the door approaches closed position, the rollers 46 ride over the front edges of the band 23, causing the leaf springs 41 to be ilexed outwardly so that when the rollers drop into the openings 5| they are held therein under spring tension to hold the door closed well enough to prevent accidental opening thereof.

It is believed the foregoing description conveys a good understanding of my invention, and while the invention is here disclosed as applied specically to cooking ranges for the broilers thereof, it should be clear that it may be applied to other cabinet structures also, wherever a drawer having a hinged front presents need for automatic kick-out of the drawer as the door is opened.
