Specification of Letters Patent.

Patented July 113, 1915..

Application filed April 16, 1915. Serial No. 21,657.

To all whom it may concern:

Be it known that I, FRED E. WHITE, a citizen of the United States, residing at Gardner, Massachusetts, have invented certain new and useful Improvements in Ovens, of which the following is a specification.

My present invention relates to improvements in ovens designed for use in connection with oil and gasolene stoves and has for its object to provide an oven with a door having means whereby it may be easily fastened in its closed position and as easily unfastened or opened, and when closed will produce an exceedingly tight joint at the upper edge.

With these and other objects in view, the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An oven constructed in accordance with my invention is illustrated in the accompanying drawings, in which,

Figure 1 is a view with the door open, and Fig. 2 is a transverse sectional view.

Referring by reference characters to this drawing, the numeral 1 designates the body of the oven which may be of the ordinary or any suitable form or construction. At the front of the oven and closing the front opening 1 thereto I provide a door 2 of sheet metal which is hinged at its lower edge by hinges which support it in a horizontal position when opened outward. These hinges are formed by projecting arms 2 secured to the corners of the door and entering vertical slots 4 in the front wall of the oven. The arms have on the under sides or edges recesses3 in which the lower edges of the slots rest and on which the arms pivot in the swinging of the door, the opposite sides of the arms being curved on arcs of I circles concentric with recesses 3. These curved portions indicated at 3* terminate in recesses 3 from which point the edges 3 of the arms extend at right angles to the plane of the door, coacting with the front wall of the oven above the slots to form stops to hold the door in horizontal position. The edges,

3 are curved on arcs of circles concentric with recesses 3 and when it is desired to remove the door altogether from the oven all that is necessary is to lift the hinged edge (while the door is in horizontal or shelf position) until the recesses 3 engage the upper edges of the slots, whereafter the swinging of the door upward will cause the arms to pivot on the upper ends of the slots and bring the inner angular portions of the arms into the slots in position to be drawn therefrom by a direct outward movement of the door.

In order to hold the door closed with a tight joint, I provide an extremely simple form of locking device capable of being op erated by one hand. This comprises an overturned or hooked edge 5 on the upper or free edge of the door adapted to engage a flange or rib 6 on the top of the oven these parts extending the width of the door. The slots 4 in the oven wall are long enough in relation to the arms to permit a limited vertical movement of the oven door sufiicient to enable the hooked edge or flange 5 to be hooked over or engaged with the rib 6 thus not only looking the door in closed position but forming a very tight joint. The hooked or flanged edge 5 is preferably formed with an inclined wall so that the weight of the door tends to keep it pressed. against the front wall or face of the oven.

I claim as my invention:

1. A domestic oven having a front opening and a door hinged at the lower edge of said opening and so as to have a slight vertical movement adapted on closing to have a tongue and groove connection with the oven at the top, the door being lifted to engage and disengage the tongue and groove.

2. A domestic oven having a front opening, a door hinged at the lower edge of said opening, said door having at is upper edge a downwardly facing groove, and a rib or flange carried by said oven engaging said groove when the oven door is closed, the door having a slight vertical movement to engage and disengage the parts.

3. An oven having a door opening with slots near the lower corners thereof, and a the upper edge of said door, and a rib on the door having arms projecting from its coroven for engaging said hook-shaped flange. 10 11ers into said openings, said arms having In testimony whereof I afiix my signature notches to rest in the 'lower ends of the slots in presence of two witnesses.

and parts projecting beyond said notches to FRED E. WHITE. engage the oven walls when the door' is open, Witnesses:

said-slots being longer than the widths of F. L. MIDDLETON,

the arms, a hook-shaped flange carried by JAMES M. SPEAR.
