Abstract: 946,176. Oven doors mechanism. TAPPAN CO. May 11,1962 [Oct. 10,1961], No. 18287/62. Headings E2F and E2M. [Also in Division F4] A removable drop down door of an oven has counter-balance mechanisms within the door, the oven door 12 comprising glass panels 12 1 , a closing mechanism engaging the catch 14, an outer wall 16, a door liner 17 and one counter-balance and support mechanism on each side of the door. Each mechanism has a U-shaped channel 18, a counter-balance tension spring 19 fixed at one end by a screw 20 and attached at the other to a bracket 21 which slides in the channel 18, a hinge pin 27 fitting in a slot 31 and a support lever 23 pivotally fixed to the bracket 21 and the pin 33. A latch bar may enter the slots 38 and 39, thus locking the bracket 21 when disconnecting the door. The pivot connections at 33 and 27 are formed with open cam hooks so that the door is easily releasable. Sealing means 15 are provided around the frame 13.
