Description
Oct. 15, 1929. w. D. ANTRIM OVEN DOOR AND HINGE THEREFOR Filed 001;. 11. 1928 MHHMEIQ my "fan Patented Oct. 15, 1929 NITED STATES PATENT OFFICE WILLIAM D. ANTRIM, OF GLOUCESTER, NEW JERSEY, ASSIGNOR T0 ROBERTS & MAN- DER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA OVEN DOOR AND HINGE THEREFOR Application filed October 11, 1928.
My invention relates to certain improvements in oven doors, of the type in which the hinge is usually at the bottom of the door and which, when opened, will remain in the full open position but which, when raised, will be closed by a spring.
One object of my invention is to utilize a flat spring for closing the door.
A further object of the invention is to provide a spring-hinge, the spring of which can be removed through the door opening and replaced in case of repairs.
And a still further object is to so arrange the spring that it will lock the door to the frame, so that other means are not necessary to retain the rocking hinge elements to the door frame.
The invention also relates to certain improvements in flat springs.
In the accompanying drawing:
Fig. 1 is a front View of suflicient of a door frame, with the door in closed position, to illustrate my invention;
Fig. 2 is a rear view of the same; I
Fig. 3 is an enlarged view of a portion of Fig. 2, showing the details more clearly than in Fig. 2; v
Fig. 4: is an enlarged sectional View on the line 44:, Fig. 2, the door being in a closed position;
Fig. 5 is a view similar to Fig. 4: with the door in an open position;
Fig. 6 is a sectional view on the line 6--6, Fig. 2;
Fig. 7 is a detached perspective view of one of the hinges; and
Fig. 8 is a perspective view of the spring.
Referring to the drawing, the frame 1 is of the ordinary type and may be of any shape or ornamented as desired. The frame has a cross-bar 2 rounded at its upper edge as at 3 to form a rocking surface for the door 4-. This door, in the present instance, consists of a frame having an inset panel 5 of sheet metal and has a lining 6 held by any suitable means to the door frame.
On the door are integral projections 7 which form the hinge members of the door. These sections are located at each end of the door as clearly shown in Fig. 2. The projec- Serial No. 311,822.
tions have curved sockets as at 8 which rock on the curved portions 3 of the frame, as clearly shown in Figs. 4 and 5, when the door is moved from the closed position to'the open position, or vice versa.
At the centre of the cross-bar 2 of the frame is an abutment 9, clearly shown in Fig. 6. This abutment is in the form of an overhung bracket, and resting against the abutment is a flat spring 10, of the shape clearly shown in Figs. 3 and 7, the spring being preferably Wider at the centre than at the ends. The ends of the spring rest in pockets 11 of the hinge extension 7, as clearly shown in Figs. 4, 5 and 6, so that when the spring is in place the tension on the spring tends to close the door, but when the door is in the open position as in Fig. 5, then the spring has not sufficient power to close the door, and the door remains in the open position until it is raised above the horizontal, when the spring will act to close the door automatically.
It will be, noticed that the surface 12 on the underside of the abutment 9 is rounded, and as the ends of the spring are raised from the position shown in Fig. 4 to that shown in Fig. 5 when the door is opened, the centre of the spring rocks on this curved surface to that shown'by dotted lines in said figure.
It will also be noticedthat there is an open throat at 13 between the overhanging abutment 9 and the lower portion of the bar 2, so
from the position shown in full lines, Fig. 6,
that the spring can be removed or one inserted through this opening, and when the door is in the partly open position, the spring is then removed through the door opening and can be replaced in the same manner, obviating the necessity of dismantling the stove or detaching the lining of the oven.
I claim 1. The combination of an oven frame; a cross-bar having rounded rocking surfaces near each end; an overhung abutment at the centre thereof; a space between the abutment and the lower portion of the cross-bar; a door having hinge members; and a flat spring resting against the underside of the abutment,
upper side of the hinge members.
2. The combination of an oven frame; a cross-bar having rocking surfaces for the hinge 01 the door; an overhung abutment, the under bearing surface of the abutment being curved and having a projecting lug at its end to retain a spring in position; a door; hinge members projecting from the door and arranged to rock on the curved surface of the frame and having pockets; and a fiat spring located back of the abutment and resting in the pockets of the hinge members.
3. The combination in a door frame, of a door having pivots adapted to the frame; members projecting from the door beyond the pivots and shaped to receive the ends of a 7 spring; and a spring located in the frame and having a centre bearing free to rock there on, the ends of the spring engaging the projecting members of the pivots of the door and held under tension to retain the door in its closed position, and when the door is opened the spring Will be flexed and turned by said members Which project from the door hinges.
l. The combination of an oven frame; an overhung abutment projecting at the rear of of said frame and near the centre thereof; a door pivotally mounted on the tame; projections extending beyond the pivots of the door, said projections having pockets; and a spring located under the overhung abutment on the frame, the ends of the spring resting in the pockets of the projections of the door, tending to hold the door in the closed position, the spring yielding and turning on the abutment When the door is moved to its open position.
WILLIAM B. ANTRIM.
