9 Claims.

This invention relates to oven drawer and door mechanism and more particularly to structure by which the door of a range compartment may be opened part way to expose the interior without moving the drawer therein while further movement of the door causes the drawer to move forwardly.

An object of the present invention is to provide a range compartment drawer structure in which the drawer is adapted to be withdrawn through the action of the mechanism associated with the door, means being provided for permitting the door to 'be opened to a degree suflicient to expose the interior of the compartment without efiecting movement of the drawer. A further object of the invention is to provide a range compartment with adrawer and closure therefor together with structure permitting the door to be opened partially without moving the drawer while further movement of the door causes the drawer to move forwardly in the .compartment. Another object is to provide a structure in which the drawer may be removed from the compartment independently of the automatic moving mechanism and moved within the compartment independently of the automatic mechanism. Other specific'objects and advantages will appear as the specification proceeds.

The invention is illustrated in the accompanying drawings in which Fig. 1 is a side elevational view of the oven with a portion of the wall broken away; Fig. 2 is a side elevational view of the oven partly broken away, with the side wall removed and with the door in open position; Fig. 3 is a fragmentary detail elevational viewof a portion of the link mechanism used in moving the drawer in the oven; Fig. 4 is a fragmentary vertical sectional view taken along line 4 of Fig. 1; Fig. 5 is a fragmentary detail elevational view of the mechanism for engaging and moving the drawer within the oven; and Fig. 6 is a fragmentary detail elevational view of the rear portion of the oven drawer.

In the illustration given, A designates a range frame providing a compartment therein; B, a door closing the compartment; C, a drawer mounted within the compartment for withdrawal; and D, mechanism for causing the drawer to move after the door has been lowered a predetermined distance.

The range A may be of any suitable construction or type. It is suflicient for the purposes of the present invention that the range provide a space or compartment therein in which the drawer C may be mounted. Since range conplate 29, the pivot being indicated by the nustruction is extremely old and well-known, a detailed description of the structure shown is believed unnecessary. The compartment may be.

a broiler oven compartment, 9. baking oven compartment, or any other compartment within the range. It is merely necessary that the range frame provide a space into which the drawer C be moved and with a front closure for the space.

The broiler drawer C may be of any suitable construction. In the illustration given, it is of old and well-known construction and need not be described in detail. The drawer is equipped with rollers I0 engaging a' roller track H carried within the compartment by means of which the drawer can be readily reciprocated within the compartment. On one side the drawer C is provided with a pin l2, to bring about the movement of the drawer in the manner hereinafter .described.

Door B may also be of any suitable construction, no novelty in the door being required. In the illustration given, the door is provided with a hinge I3 which is supported by bracket 14. Fixed to the door B at one side thereof is a curved actuating bar I 5 which is used in conjunction with the mechanism D for bringing forward the drawer after the door passes a predetermined point.

The mechanism D may be constructed in a number of ways, one specific illustration being given in the drawings." An angle bar It is secured in the base portion of the range and along the lining portion at one side, as illustrated in Figs. 1, 2 and 4. Pivotally secured to the vertical flange of the angle bar It is a link'member II. A spring l8 engages link l1 and a lug IS with which the angle bar is provided and normally urges the link I! in a backward direction. Pivotally connected to the link H at its upper end is a small link 20 provided at its top with an inwardly extending pin 2|. A washer22 extends against the link 20 and over the pin 2|, and is confined in position by a cotter pin 23, which extends through the pin 21. The pin 2| extends through a slot 24 in the compartment wall 25. The slot 24 is formed by turning inwardly the slot portions to form flanges 26. The inner end of the pin 2| is secured to a carriage plate 21, the plate 21 having outwardly turned flanges 28 slidably engaging the horizontal flanges 26 of the compartment wall 25. Pivotally secured to the inner side of the carriage plate 21 is a latch meral 30. Plate 29 has a downwardly extending portion 3| having a perforated end engaged by the book of spring 32. The hookat the other end of the spring engages an opening in the flange 28 of plate 21,

At its upper side, the plate 29 is provided with inclined sides 33 which lead toward a deep slot 34, the slot 34 receiving the pin I2 of the drawer 0.

Connected to the link H at a point above the lower end thereof is an actuating link 35. Link 35 carries at its lower end a pin 36 which engages an arcuate slot 31 in the link member II, thus providing a lost motion connection between the two members. The upper end of the link 35 is pivotally connected at 38 to the bar l which is rigidly secured to the door B.

Operation In the operation of the apparatus, when it is desired by the operator to look into the interior of the oven or other compartment, the door B may be dropped to the. half way position illustrated in dotted lines in Fig. 2 without effecting any forward movement of the drawer C. In this movement, it will be noted that the curved bar l5 swings in a curved circuit which serves to raise the actuating link 35 but not to advance it. In this movement, the bar I5 is obliged to swing rearwardly a short distance in the initial movement, and this movement is compensated for by the arcuate slot 31 in the link II. In other words, an actuating link 35 is permitted to move rearwardly a little without moving link I! by reason of the slot 31 to permit the lever l5 to swing in a semicircular path from the lower position, as illustrated in Fig. l, to the elevated position, as illustrated in full lines in Fig. 2. When the bar I! has swung to the half way mark indicated in dotted lines in Fig. 2, it will be noted that for the first time, the link 35 is in a position to be drawn forwardly, carrying with it the links I1 and 20.

At the half way point just described, the operator may allow the door to stand, the link 35 extending in a straight line between the bar l5 and the lever l1, and in this position a full view of the interior of the compartment and drawer is obtained. Further, in this position, a fairly quick cooling of the interior of the compartment can be brought about without moving the drawer and its contents. Should the operator desire to have the drawer brought forward and partially withdrawn from the compartment, a further lowering of the door to the position shown in full lines in Fig. 2 brings the drawer C forward to the position illustrated. In bringing this about, the bar I5 attached to door B draws forwardly the link 35 and thereby brings links I! and 20 to the position shown in full lines in Fig. 2. As link 20 is advanced, pin 2| carried thereby advances the carriage plate 21 and in turn the latch plate 29. The latch plate 29, which carries the drawer pin l2 within slot 34, causes the pin l2 to be advanced and thereby the drawer 0.

Should the operator desire to withdraw the drawer to an even further extent, this can be done by raising the portion of the drawer adjacent the door so as to free the pin l2 from slot 34 of latch plate 29. The drawer may then be advanced with the rollers l0 remaining in the channels I 1 until the drawer is removed from the oven, if this is desired. Likewise, if desired, the drawer may be raised to free the pin I2 from notch 34 and at the same time the drawer may be moved rearwardly of the latch plate 29. In

either of the latter positions, the drawer may be moved independently of the carriage. To replace it upon the carriage, it is merely necessary to move the drawer backwardly or forwardly, as the case may be, to bring the pin l2 against latch plate 29, in which event, the cam surfaces 33 cause the pivoted latch 29 to swing downwardly so that the pin l2 may enter the slot 34.

When it is desired to close the door and have the drawer C withdrawn, a slight upward movement of the door brings about this result, the returning movement being assisted by the spring i8.

It will be noted that the actuating structure D is extremely simple and compact and that 'it is housed within a side wall portion of the range. thus not occupying utility space.

The apparatus enables the operator to open the compartment to examine the contents without moving the contents of the drawer and, likewise, to open the drawer the desired distance to cool the same without disturbing the contents by movement, but when a forward movement of the drawer is desired, this is selectively controlled and brought about by a further downward movement of the door. At the same time, the drawer can be operated independently of the automatic door advancing mechanism by slight and foolproof movements of the drawer itself.

It will be noted that if the drawer is raised and'pushed in for broiling with the door left open, or if the drawer is pushed to this position for any other reason, the mechanism picks up the drawer, when the door is closed, the spring-urged latch plate 29 engaging the pin 12 of the drawer. The drawer will then operate with the door movement above described.

While in the foregoing description, we have set forth certain details as illustrative of one mode in which the structure may be formed and operated, it will be understood that the details of such structure may be readily modified by those skilled in the art without departing from the spirit of our invention.

We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
