' ATTACHMEN OR DRAWERS IN OVENS OF STOVES 0R RANGES 2 Sheets-Sheet 2 Filed April 29,, 1946 Patented June 14, 1949 ATTACHMENT FOR DRAWERS IN OVENS OF STOVES OR RANGES v James P. Burt, Taunton, Mass., assignor to Glenwood Range Company, Taunton, Mass, a corporation of Massachusetts Application April 29, 1946, Serial No. 665,745

3 Claims. 1

The invention relates to an attachment for oven drawers of stoves or ranges, and especially broiler drawers, by which the position of the drawer is controlled by the opening and closure of the oven door.

The object of the invention is to improve and simplify the means by which the drawer is moved out and in by the opening and closing of the door, and especially to provide means by which the drawer will be moved in such manner that its contents will not spill if the door is quickly opened from a full closed position or quickly closed from a full open position.

The invention can best be seen and understood by reference to the drawings in which *Fig. 1 is a perspective of the combined oven and drawer showing their general relationship and especially the position occupied by the drawer when the door is full open.

Figs. 2, 3 and 4 are views mainly in plan showing the various positions occupied by the operating parts which control the position of the drawer upon the opening and closure of the door; Fig. 2 showing the normal position of these parts when the oven door is closed, Fig. 3 their position when the oven door is partly open, and Fig. 4 their relative position when the oven door is full open.

Fig. 5 is a side elevation, especially that of the operating parts.

In the drawings-- I represents an oven forming part of a range and having a bottom 2, and sides 3 and 4. The open front of the oven or doorway is closed by a door 5 hingedly mounted. This door when full closed occupies a position as shown in Fig. 2 substantially normal to a vertical plane passing through the longitudinal center of the oven bottom, and when full open as shown in Figs. 1 and 4 will occupy a position substantially parallel to said plane if the plane be continued, with preferred slight angular turning beyond said parallel position as shown.

Located within the oven is a drawerB which is withdrawn from the oven when the door is opened, and returned into the oven as the door is closed.

The drawer may be mounted to easily run in and out of the oven in any suitable manner, its mounting forming no part of the present invention which pertains to the mechanism or linkage by which the opening and closing of the door controls the position of the drawer.

Fastened to the bottom 2 of the oven is a strap I.

This strap has a raised central portion 8, and at one end is provided with an upturned flange 9 forming a stop. The strap is located at the fore part of the oven bottom laterally offset from said plane and between it and the adjacent side 3 oi the oven.

Pivoted to the raised portion 8 of the strap and to a bracket ID on the inside of the oven door is a-linkage composed of a series of levers which lie between the oven bottom and the bottom of the drawer and turn in planes parallel thereto but spaced therefrom. Of these the lever l I is pivoted to the raised portion of the strap and when occupying an outwardly turned position, corresponding relatively with the full open position of the door as shown in Figs. 1 and 4, extends in a direction substantially normal to the plane previously referred to, and when occupying this position is preferably of a length to extend from the point of its pivotal connection to a point adjacent the furthermost side 4 of the oven. From this position the lever is turnable to swing inwardly to an inwardly turned position corresponding relatively with the full closed position of the oven door as 1 shown in Fig. 2. When occupyin its inwardly turned position the lever extends in a direction substantially parallel with the plane previously referred to, and as the lever is turned to either approach or leave its inwardly turned position the free end of the lever will move in a direction substantially normal to said plane. In practice it is preferred that the lever in approaching or leaving its inturned position will not only pass throughsaid plane but also through a second plane parallel with the first mentioned plane laterally offset therefrom and passing through the pivotal connection of the lever, the free end of the lever, as the lever is turned to approach or leave its inturned position, then moving in a direction substantially normal to both of said planes. Pivotally connecting with the free end of the lever II and extending to connect pivotally with the fore end portion of the oven drawer within the central longitudinal line of the drawer is a lever l2. Pivotally connected to a bracket [0 on the oven door adjacent its hinged side and extending to pivotally connect with the lever ll between the free end of this lever and the point of its pivotal mounting, is a lever l3.

Arrangement of the combined levers with relation to each other and to the drawer and door is such that when the door is closed and the lever H is occupying its inwardly turned position as shown in Fig. 2 the lever will be turned by the initial opening of the door so that its free end will move in a direction substantially normal to the planes previously referred to with theefiect of then imparting substantially no movement to the drawer for moving it out of the oven. In other words, if the door is quickly opened substantially no movement will be imparted to move the door but a lag will occur and the movement of the drawer will be very gradual, and it is not until the opening of the door increases that the free end of the lever will be turned with increasing degree of outward progression as to rapidly move the drawer out of the oven. As the door approaches its full open position, which is defined by engagement oft ill come to move in a :ormal to the plane passing through the longitudinal center of the oven bottom as DIGVlOllSlX" referred to and consequently willoperate to move the lever II with a very slow movement; as the lever is brought into its outwardly turned position" corresponding with the full openposit on of the. oven door as defined by the stop; In other words, the drawer as it is moved out will not only have: a very slow starting movement. but as it approaches the end of its withdrawal 1t W111 then have a very slow movement which becomes prac1- tically negligible at the end of the movement.

'Areverse operation takesrplaceas the door is closed and the drawer moved into the oven. At the start thedrawer will be.- moved very slowly with the return speedl increasing until the drawer approaches the end of its return movement when. its' movement ag-ai'n becomesvery slow' and prac-- 1182188791 ll withthe stop 9, it. direction substantially ticall'y'neglig-ible, the drawer being brought grad- I ually to a position of. rest.
