Original application May 21, 1934, Serial No. 726,705. Divided and this application October 5, 1934, Serial No.746,966

2 Claims. (01. 126-190) This invention relates in general to stove construction and has more particular reference to improvements in the construction of doors for ovens, broilers, and stoves or ranges using any desired fuel. This application is a division of my co-pending application Serial No. 726,705, filed May 21, 193i. A principal object of the invention is the provision of a door structure unit which may be readily assembled within or removed from a range or the like without disturbing the relationship of the counterbalancing means within the range or stove proper with respect to the door structure 16 Another important object of the invention is the provision of adoor structure of this character in whichthe pivot pins for the doors are I readily adjustable and removable from operative position to permit the entire door to be removed 5 from its position with a minimum amount of effort.

Numerous other objects and advantages of the invention will be apparent as it is better under stood fromthe following description, which,

25 when taken in connection with the accompanyin elevation, of the door and the hinges for thesame; and

Fig. 5 is a fragmentary sectional view showing 40 a hinge pin for the door and its mounting.

For the purpose of illustrating my invention, I have shown on the drawing an oven or stove, indicated generally by reference character I,

- provided with a compartment which is accessible 45 by a door 2. The door opening is surrounded by a frame I which closes the space between'two panels of which the double walls of the oven are made. The frame is of angular cross-section and is provided adjacent the lower portion of 50 the door opening at both sides with slots 4. These slots are covered by the door when the latter is closed.

Thedoor structure 2 comprises an inner panel I and an outer panel 5' united along their cir- 65 cumferential edges by a flange 6, and a l is secured to the exterior flange or framework of the door by screws or other suitable fastening means 1'.

Pivot pins 8 are mounted adjacent the lower edge of thedoor structure in the interior there-v .5

- In the space between the two panels 5, 5' adjacent the circumferentialfiange, an angular bracket II is secured which serves to guide the pivot pin 8 for rectilinear movement.- Each pivot pin 8 is of suflicient length to project through the reinforcing bar I and the flange 6 of the door structure even when the adjusting means I ii "is shifted to the inner end of the slot ll. Upon slidably advancing the pivot pin 8, the free end thereof extends through an opening II in the frame 3 of the door bpening. In this position the pins 8 pivotally support the entire door structure on the frame, and upon withdrawal of the pins the entire door structure may be withdrawn from the frame, as indicated in Fig. 5. Means are provided for permitting the door structure to be connected with a counterbalancing element and for this purpose the door is equipped with an arm I3 projecting from the bar 1 through a suitable opening in the inner panel 5 of the door and adapted to extend through the slot 4 of the frame into the space between the panels of the double wall of the stove (Fig. 1). This arm I3 is rigidly connected at one end with the door structure and at the other end terminates in a hook II to which the counterbalancing means may be attached. For this purpose, a connector element or plate I 5 is interposed between the door structure 2 and the counterbalancing means I 6. This counterbalancing means in the present instance comprises a helical spring having its lower end inserted in the hook of a bolt I? which passes through the bottom plate of the stove, and having its upper end inserted through an opening l8 in the connector I5.

The connectorelement l5 has near its upper end an elongated slot l9 to facilitate its attachment to the hook I of the arm |3,andisequipped with an additional slot 20 intermediate its ends andabove the opening l8. The arm l3,'extending from the bar I of the door structure, is provided intermediate its ends with a projecting finger 2| adapted to-engage the inner face of the frame 3 and serves asastop when the door 2 has been moved t: completely open position (Fig. 2).

the door is removed, a screw 22 is inserted from the front of the frame 3 through a threaded boss 23 on the inside of the stove frame. This screw is of sufficient length to project through the slot 20 in'the connector plate l5.

when it is-desired to remove the door entirely from the stove, the door is brought to a full open position (see Fig. 2). As the door assumes this open position the spring I6 is extended to its maximum length through the pull exerted by the hook ll upon the connector plate l5, and the screw ,22 is then inserted through the slot 20. The pivot pins 8 are then slid out of the openings liand the door is removed as shown in Fig. 3. It will be apparent that the screw 22 thus holds the counterbalancing spring and its connector plate firmly against any longitudinal displacement while the door is removed from position.

When it is desired to assemble the door withthe stove or oven, the door is positioned properly, the hooks ll are inserted in the slots I! of the connector plates, the pivot pins 8 are then inserted in the openings l2 in the frame. The door is now in operative position with respect to the counterbalancing means and the screw-fl'may be removed. I g

It is thought that the invention and many of pivotal support for the door, secured to theme] and through which said pin slidably extends, and means inserted in the pin and projecting from the panel for effecting longitudinaladjustment of said pin. V
