OVEN DOOR.
' Application led November 16, 1923. Serial No. 675,113.
To all 'whom z't may concern.'
Be it known that we, GEORGE D. WILKIN- s'oN and AUGUSTUS F. HARTER, citizens of the r United States, residin at Oak Park, in the county of Cook and tate of Illinois, have invented new and useful Im rovements in Oven Doors, of which the ollowing. is a specification.
This invention relates particullarly to oven doors; and the primary object is to provide .an improved construction involving the use of an outer sheet metal panel constituting the main body of the door, an inner sheet A metal lining, and a pair of trunnions havv-port the door and any superimposed weight ing reenforcing shanks'housed between the main panel and the lining. Such a construction provides'for the supporting of the door and any load which may be imposed upon it Awhen they door is inopen condition by the trunnions and the shank-extension thereof, which suitably may be made of cast iron and of suiiicient strength to readily supor trunnions and its bearing; Fig; .5, a
broken perspective view showing one corner of the lining member of the door; Fig. 6, a
broken perspective view showing one corner portion of the main panel of the door; Fig.
7, a broken vertical sectional view illustrat- 1 ing an'improved latch for the door, the section. being taken as indicated at line 7 .of Fig. 1'; Fig. 8, a plan view of a door, illustrating a modification, the lining being removed; Fig. 9, a broken perspective .view illustrating another modification in which the trunnions which support the door are of another form); and Flg. 10, a broken vertical sectional view taken as indicated at line 10 of F-ig. 9.
' Referring to Figs. lto 7 inclusive, A represents the frame of a range which is provided with ovens equipped, with doors A" flanges and A2. In this embodiment of the invention, the frame A is equipped with bearings, or journal boxes B for the trunnions of the doors. The members B are provided with stops 1 which are adapted to limit the down ward swing of the door. The doors A and A2 fare of the same construction and mounted in the same manner.` A description of one will suflice, n'
The door A comprises a main outer sheet metal panel 2 which is bowed outwardly and is provided at its periphery with end lianges 2a, a lower flange 2b, and an" upper flange 2; an inner sheet metal panel 3, which is provided lat its margins with end flanges 3,
a lower flange 3", and an upper flange 3; trunnions 4 received by the bearings Band equipped with shanks 4a which are housed in the space between the outer and inner panels '2 and 3; a handle 5` secured to the upper portion of the door; -and a latch 6 carried-by the frame A and adapted to engage the upper edge ofthe door` when the door is in the closed position.
The flanges 'of the main panel 2 ofthe door are notched at the lower corners of the door, as indicatedy at 7 to accommodate the sli'anks ofthe trunnions 4. Also, the flanges of the lining panel 3 are notched at the lower vcorners of the door, as indicated at 7. The ianges of .the outer and inner panels of .the door' have a telescopic relation, that is, the flanges of the lining member lit inside the flanges of the main panel.. The notches,
therefore, are complementlal 'and afford passages for the shanks of the trunnions. The
shank 4* of each trunnion preferably comprises a base portion 4b which extends through the notches at the corner ofthe door, and an arm 4c rising from the portion 4" and extending obliquely and terminating at the-upper will be noted that t e main. anel 2 of the door is so pressed as to' provi e a peripheral marginal shelf or" bearing 8 adjacent the' the interme' 'diate or main portion of the body of .the sheet being pressedY or dished outwardlyso of the member,
as to'lie in a different plane. The portions 4". of the Shanks ofthe trunnions bearupon the shelf' portion 8 at the lower portion of the door. At the .upper ends of the arms4" are small extensions 4" which bear upon the marginal bearing 8. The arms 4 are also equipped near their upper ends with ofset lugs or feet 4 which bear upon the depressed which may have nickel plated heads. The portion of the panel 2 at the points where construction is strong, sanitary, and thorthe handle 5 is connected, the metal at these oughly adapted to its purpose. points being struck inwardly slightly, how- The latch device 6 shown yiii Fig. 7 comever, as indicated at 9. Theouter panel 2 prises a flat spring mounted on a ledge 6@l 1S secured to the portions 4b and 4e by stove carried by the frame A and disposed inside bolts or screw bolts 10 which engage nuts the upper edge of the door, the spring being 11. The upper bolts 10 pass through the suitably shaped and extended through 'an base portions of the brackets 5a of the hanopeningfb in the frame. The outer end of dle, so that the same bolts which secure the the spring is curved into the form oa ring upper ends of the arms4c to the main panel 6c, the lower portion of which Serves as a of thedoor serve also to secure the handle latch for the door'.
