OVEN

Application filed May 31,

This invention relates to racks for the ovens of cooking stoves, and has for one of its objects 'to provide a novel and simple means through the medium of which a rack of this character may be so connected to the door of its oven as to effect the withdrawal of the rack from the oven when the door is opened and the movement of the rack into the oven as the door is closed, to the end that articles may be placed upon the rack and examined from time to time conveniently and without danger of burning the hands.

The invention has for a further object to provide means of the character stated which shall be adapted to effect the withdrawal of the rack from the oven during the final and smaller phase of the opening movement of the door, and which shall be adapted to efiect the movement of the rack into the oven during the final and smaller phase of the closing movement of the door, to the end that all liability of the rack and door contacting and interfering with the movement of each other will be avoided.

The invention has for a further object to provide a novel means for supporting the rack in the oven for free sliding movement outwardly and inwardly with respect thereto.

' With the foregoing and other objects in view, the nature of which will appear as the description proceeds, the invention consists in the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustratedin the accompanying drawings, wherein Figure 1 is a sectional view taken on a plane extending vertically and longitudinally through an oven equipped with a rack and rack' operating means constructed in accordance with my invention;

Figure 2 is a sectional view taken on the vertical plane indicated by the line Q2 of Figure 1;

Figure 3 is a sectional view taken on the horizontal plane indicated by the line 33 of Figure 1;

Figure 4: is a sectional view taken on the vertical plane indicated by the line 44 of Figure 5 is a sectional view taken onthe SEATTLE; WASHINGTON RACK 1930. Serial No. 458,422.

vertical plane indicatedby the line 5-5 of Figure v Referring in detail to the drawings, 1 designates the oven of a cooking stove, 2 designates the door, and S t/he rack of the oven. The door 2 is hinged at its lower end, as at 4, and the rack 3 comprises a frame 5 which is slidably mounted for movement into and out of the oven 1, and shelves 6 which are carried by the frame. The frame 5 comprises sides fflwhich are of skeleton forma tion and are connected together at their lower edges by cross bars 5*. Supports 7 for the shelves 6 are carried by the frame sides 5*, and are arranged in vertically spaced rela-* tion to permit the shelves to be supported at the desired or required distance abovethe bottom 8 of the ovenl.

The rack 3 is slidably supported by means which comprises rollers 9 journaled, as at 10, upon the frame sides 5 andresting upon the horizontal rails 11' secured to the sides 12 of the oven'l. This'means also comprises rails 13 secured to the frame sides 5 xand resting upon rollers 14 journaled, as at 15, upon the oven sides 12. The rack suspending elements are arranged near the upper sides of the oven 1 andrack, the rails 11 extend from the front to the rear side of theoven, and the rails 13 extend from the front side of the rack'to points rearwardly beyondthe vertical transverse center of the rack. The rack 3 is, when in projected position with respect to the oven 1, held against tilting movement by rollers 15 whichare journaled, as at 16, on the frame sides 5* near the lower rear corners of the rack and contact with the lower sides of horizontal rails 17 which are carried by the oven sides 12 and extend. from the front to the rear side of the oven. I The rack 3 is connected to the door 2 by means which is adapted, during the final and smaller phase f the opening movement ofthe door, to withdraw the rack from the oven 1,

and which, during the final and smaller phase a of the closing movement of the door, moves the rack into the oven. This means comprises levers 18 which extend through openings 19 inthej oven bottom, 8 and are pivotally connected near their o er ends, as at PATENT OFFICE 20, to the oven bottom, arms 21 which extend forwardly from and are arranged at right angles to the lower hinged end of the door 2, and links 22 which are pivotally connected, as at 23, to the lower ends of the lever 18, and are pivotally connected, as at 24: to the outer ends of the arms. This means also comprises channeled keepers 25 which are carried by the rack 3 and are secured in vertical position on the frame sides 5*. The keepers 25 are located on the upper portions of the rack 3 and centrally between the front and rear sides of the rack, and the upper ends of their rear sides 25* are located in planes below the corresponding ends of the front sides 25 so as to provide an en trance 26 to thekeepers. The levers 18 are provided at their upper ends 'with'rollers 27 which extend at right angles therefrom and during the operation of the levers move into and out of the keepers 25 by way of the entrances 26.

When the door 2 isclosed, the levers 18 oocupy the upwardly and rearwardly inclined position in which they are shown by solid lines in Figure 1, and when the levers are in this position they are free of all engagement With the rack 3. During the opening movement of the door 2, the upper portions of the levers 18 are swung forwardly with respect to the rack 3 and keepers 25.

This movement of the levers 18 continues during the first and larger phase of the opening movement of the door 2. On the completion of thismovement of the door 2, the rollers 27 enter the keepers 25 by way of the openings 26 and the levers are in vertical position, as indicated by broken lines in Figure 1. During the final and smaller phase of the opening movement of the door 2, the levers 18 move forwardly, and during this movement of the levers they, since the rollers 27 are in the keepers 25, move the rack 3 into extended or withdrawn position with respect to the'oven 1. The levers 18 are now in forwardly inclined position and during the first and smaller phase of the closing movement of the door 2, they are returned from this position to their vertical-position. During this movement thereof, the levers 18 return the rack?) into the oven 1. The rollers 27 are now in registration with theopenings 26 of the keepers 25, and during the remaining and larger phase of the closing movement of the door 2, the levers 18 return to their upwardly and rearwardly inclined position.

Horizontal rollers 28 which are ournaled, as at 29, on the frame sides 5 near the rear ends of the latter and contact with the sides 12 of the oven 1, and horizontal rollers 30, which are journaled, as at 31, on the oven sides and contact with the frame sides, serve to hold the rack 3 against any sideslipping lor swinging while it is being withdrawn from or returned to the oven.

It should be apparent from the above description, taken in connection with the accompanying drawings, that the rack 3 is supported for free sliding movement into and out of the oven 1, and that it is connected to the oven door 2 in a manner to prevent any contact between it and the door that would tend to interfere with the free opening or closing of the door or the free inward. or outward movement of the rack, and that the rack, the means for supporting it and the means for connecting it to the oven door are simple, durable and capable of being manufactured at a comparatively low cost.

While I have described the principle of the inventiomtogether with the structure which I now consider the preferred embodiment thereof, it is to be understood that the structure shown is merely illustrative and that such changes may be made, when desired, as fall within the scope of the invention as claimed.

I claim 1. In combination, an oven having a hinged door, a rack, means supporting the. rack for sliding movement into and out of the oven, a keeper carried by the rack, a lever pivoted to the oven and occupying a position beyond the keeper when the door is closed, means connecting the lever to the door for movement in the direction of the keeper during the first phase of theopening movement of the door, and means carried by the lover and adapted to engage the keeper when the lever reaches the keeper to permit the withdrawal of the rack during the remaining phase of the opening movement of the door and to permit the lever to move the rack back in the oven durin g the first phase of the closing movement of the door.

2. In combination, an oven having a hinged door, a rack, means supporting the rack for sliding movement into and out-of the oven, a lever pivoted between its ends to the bottom of the oven and provided at its upper end with a roller, an arm secured to the door, a link connected to the arm and lower end of the lever, and a vertical keeper carried by the rack and provided at its upper rear side with an opening.

3. In combination, an oven having a door hinged at its lower end, a rack, means supporting the rack for sliding movement into and out of the oven, a lever hinged near its. lower end to the bottom of the oven and pro vided at its upper end with a roller, an arm secured to the hinged end of the door and extending forwardly and at right angles therefrom, a link secured to the lower end of the lever and to the outer end of the arm, and a channeled keeper secured to the rack and provided at its upper rear end with an opening.

In testimony whereof I hereunto aflix my signature.
