OVEN STRUCTURE FOR GAS-RANGES;

Patented Oct. 1 1, 1919.

Application filed July 9,1918. Serial 1%. 244,079.

To all whom it may concern:

Be it known that I, CLARENCE V. Ronnn'rs, a-citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Oven Structures for Gas-Ranges, of which the following is rangement of the oven door so that it can be readily raised and lowered, the door coming in contact with a base plate-and not swiveled on pivot pins as heretofore.

In. the accompanying drawings Figure 1 is a front elevation of my im proved gas range;

Fig. 2 is a sectional View on the line 22,

Fig. 3 is a sectional view on the line 3.3, Fig. 4;

Fig. 4 is a front elevation of one side of the door and frame, showing the hinged portion; p

Fig. 5 is a sectional view on the line 5-5,

ig. 6 is a detached perspective view of a portion of the frame;

Fig. 7 is a detached perspective View of one corner of the door;

the cap plate, which is adapted to the frame and incloses the hinged portion of the door;

and

Fig. 9 is a view on the same section as Fig. 2, with the door in the open position.

Referring to the drawings, 1 is the oven section of a gas range and 2 is the section having the exposed burners used for ordi- The oven portion, in the present instance, has the main oven section 3 and the broiler section 4. The front frame 5 incloses both portions of the oven section. 6 is the door of the oven section and 7 is the door of the broiler section. Both of these doors, in the present instance, are arranged so as to turn down. The frame 5, as clearly shown in Figs. 5 and 6, has an uninterrupted curved surface, which can be highly polished,

if desired, making an exceedingly attractive range.

It has been the general practice either to hlnge the doors by exposing the hinges, which project beyond the frame, or to mount the hlnged portions in projecting casings. One of the objects of this invention is to conceal the hinged portions and to inclose them within the frame so that they are not exposed to view.

8 and 9 are ca plates, one set for the oven portion an the other set for the broiler portion. The outer surface of each' cap plate is flush with the outer surface of the frame 5, as clearly shown in Fig. 5. The

.lower edge 10 of the oven door 6 rests in the rib 14 of the frame so that, as the door moves from the vertical to the horizontal position, the pins '12 will rise up into the slot and the projecting portion 20 of thecap 8 will hold, the door in the horizontal position when open. Projecting rearwardly from each of the pins 12 is'an arm 15 to which is ivoted an L-shaped plate 16 having a rod 1'? extends through a lug 18 on the frame and mounted on this rod 17 is a coiled spring 19, which tends to counterbalance the door 6. The door, in moving from the closed position, Fig. 2, to the open position, Fig. 9, rides on the portion 11 of the frame 5, while the pin 12 moves upward into the upper portion of the slot 13, the counterbalancing spring allowing for this movement. The spring, when the door is closed, overbalances the door, owing to its position, but, when the door is open to the full extent, as in Fig.

be substituted as a full equivalent of the spring, if founddesirable u By this construction, it will-be seen that the hinge, or pivot section, of the portions secured thereto, whicH"---- of the door are in the back of the front surface of the frame and there are no projecting portions of the frame. hen the cap plate is in position the entire frame can be plated and polished so as to give the frame an ornamental and attractive appearance.

I claim:

1. The combination in a range, of an oven frame having a continuous outer surface and a bearing plate; a door having laterally projecting pins near the lower portion thereof, the lower surface of said door sliding on the bearing plate of the frame, the pins on said door limiting the movement thereof; and means for balancing the door.

2. The combination in a range, of an oven frame having a continuous unbroken surface: a door mounted in the frame; the lower portion of the door being arranged to slide on the bearing plate forming part of the frame, said frame having a vertical slot at each side; a pin on the door arranged to travel vertically in said slot when moved from the closed to the open position.

3. The combination in an oven, of a frame having a curved outer surface; a door hung at its lower portion to the frame, said door being arranged to move from the open to the closed position on said frame; a pin project-ing from each edge of the door at its lower end, said frame having an elongated vertical slot adapted to receive the pin; an arm on each pin; a rod pivoted to the arm and extending through a lug on the frame; a counterbalance spring mounted on the rod and tending to balance the door; a cover plate mounted in the frame and inclosing the pin theouter-surface of said plate being flush with the surface of the frame so that the surface of the frame, when the plate is in position, will be smooth and uninterrupted.

l. The combination of the frame of an oven having a curved surface and having an opening for the oven, the frame having a recess at each side: a rib in each recess, the lower portion of the rib having an elongated not-ch: a cover plate arranged to close the recess and having a portion extending 'in front of the recess; a door mounted in the opening in the frame; a pin at each side of the door extending into the recess of the rib; an arm projecting rearwardly from the pin; and a counterbalance connected to the arm for counterbalancing the door, the door in moving from the open to the closed position, sliding on the frame and the pin moving vertical];' in the recess on the rib of the frame.

The combination in a range, of an oven frame; a door mounted in the frame; the lower portion of the door being arranged to slide on the bearing plate forming part of the frame, said frame having a vertical slot at each side; and a pin on the door arranged to travel vertically in said slot when moved from the closed to the open position.

In Witness whereof I affix my signature.

CLARENCE V. ROBERTS.
