These forked ends ofthe bars are made of a width to fit snugly between the arms 20, 2B of the elements I8 for holding the door in place against lateral displacement. 'Ihe door pivots, or turns, by the forked ends 21, 21 of the bars 28, 28 turning upon the pins 22, 22, and the forked ends of the bars are applied to the pins simply by a thrust movement. In other words, the door itself is applied to make its pivotal or hinge connection simply by a thrust movement which bringsthe forked ends of the bars into hinged or pivotal engagement with the pins on which they turn. With the hinged or pivotal connections thus obtained the axis on which the door turns lies within the door between the plates of which it is composed. The axis lies, also, outwardly displaced from the frame bar `I1 on which the door is mounted to turn, and inset from the bottom edge of the door. As the door turns from a closed to an open position the bottom edge of the door will turn forwardly and upwardly on an arc around the axis of the door. In the mounting of the door it is necessary that the pins 22, 22 on which the door is turning shall be sufliciently spaced from the frame bar I1 as to permit of such turning. It is also necessary that the axis of the door should be so positioned with relation to the bottom edge of the door that when the door is closed its bottom edge will not engage the edge of the adjacent panel 3 and will lie properly positioned in relation'to it. rIhis end is secured by adjustably securing the bars 28, 23 to the flanges I3, I3, and this adjustable retention is preferably obtained by attaching the bars to the flanges by screws 29 which pass through slots 33 in the bars and thread into the strips. This permits ofthe bars 28, 28, when the'screws are tightened, being secured in any desired properly adjusted position.

Fixed to the door offset from the points of its hinge connections and lying within the angles between the sides of the door and its bottom so as to be aligned with the bars 5 and 6 of the frame, are arms 32 which extend, respectively, through slots 33 in the back plate 8 and slots 34 in the frame bars 21 and 31. The fixing of these arms to the door is obtained by the attachment of the arms to the bars 28, 28 which are attached to the door as aforesaid. Each of the bars 28, 28 is an angle bar, one section being adjustably attached to the door and the othersection bearing against the back plate 8 of the door and it is to this section that the arm 32 is secured preferably by integral connection. In fact each angle bar 28, its forked end 21, and the arm 32 carried by it, are all died out and formed from a single blank.

The arms 32 render through the slots 34 in the frame bars as the door is opened and closed. The arms are downwardly curved arms and turn on an arc substantially co-axial with the axis of the door, Fixed to the ends of the arms are spring connections 35, the ends of which are secured within the stove to the frame bars 36 at the bottom thereof. The arms and spring connections operate to hold the door closed and to return it to a closed position when open. The tension of the springs through the arms operate, also, after the door is hung to maintain the hinge connections between the door and the elements fixed to the frame on which the door is turning by maintaining engagement between the forked ends 21, 21 borne by the door and the pins 22, 22

Formed 22 are the forked ends borne by the frame, for, as previously described, engagement between these parts is initially obtained simply by a thrust movement. The door may be lifted off after disconnecting the springs.

The door is held in a full open position by engagement between the arms 32, 32 and the side bars 21 and 31 of the frame. As the door is opened the arms 32, 32 will draw through the slots 34, 34 in the frame bars 2l and 31 until the full opening of the door when edges 31, 31 on the arms will engage the frame bars at points lying above the slots 34, 34 therein, whereupon the door will be maintained in its full open position.
