1 Claim.
The present invention relates to new and useful improvements in oven doors and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction whereby the interior of the oven may be conveniently observed without the necessity of opening the door.
Another very important object of the invention is to provide an oven door of the aforementioned character comprising novel means for illuminating the oven, also without the necessity of opening the door.
Other objects of the invention are to provide an oven door of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact, attractive in appearance and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in front elevation of an oven door constructed in accordance with the present invention.
Figure 2 is a view in rear elevation thereof.
Figure 3 is a View in rear elevation of the invention with the inner frame removed.
Figure 4 is a View in horizontal section, taken substantially on the line 4-4 of Fig. 3 but with the inner frame in position.
Figure 5 is a detail view in vertical section through a lower corner portion of the invention, taken substantially on the line 5-5 of Fig. 4.
Figure 6 is a detail view in vertical section through the handle.
Figure 7 is a vertical sectional view, taken substantially on the line I'I of Fig. 6.
Referring now to the drawings in detail, it will be seen that the embodiment'of the invention which has been illustrated comprises an outer frame I of suitable metal, said frame being substantially rectangular. In its inner side, the frame I has formed a continuous groove or channel 2. The reference numerals 3 and 4 designate trunnions on the frame I which are journalled in suitable bearings 5 for mounting the door on a stove for swinging movement in the usual manner. As illustrated to advantage in Fig. 5 of the drawings, the trunnion 3 is hollow or tubular and the bore thereof communicates with the groove 2. Formed integrally with the frame I are braces 6 which radiate from an integral ring I.
Recessed in the inner side of the outer frame I and removably secured thereto by screws 8 is a substantially rectangular inner frame 9 of suitable metal which covers the groove 2. The inner frame 9 is provided with integral braces II] which parallel the braces 6 and which radiate from an integral ring I I which is coaxial with the ring 'I. A thermometer I2 is mounted in the coaxial rings 1' and 8 for indicating the temperature in the oven.
The outer frame I has formed therein a recess or rabbet I3 which accommodates the outer marginal portions of a. pair of spaced sheets I4 of suitable transparent material, such as Pyrex. Suitable cushioning elements I5 (see Fig. 7) are provided for the edges of the transparent sheets I4. A gasket I6 spaces the transparent sheets I4, said gasket being of suitable resilient material to permit expansion and contraction. It may be well to here state that the transparent sheets l4 are secured in the frame I by the inner frame 9. The transparent sheets I4 have formed therein aligned circular openings which accommodate the rings 1 and II. As shown to advantage in Fig. 4 of the drawings, the rings I and II have formed in their outer peripheries recesses defining, in conjunction with each other, a channel which accommodates the transparent sheets I4.
Mounted on the upper portion of the frame I is a hollow handle H which comprises attaching arms I8 and IS. The arm I9 is tubular (see Fig. 7) and establishes communication between the hollow handle I7 and the groove 2. Mounted in the hollow handle I! is an electric socket 20 in which an elongated incandescent electric lamp 2| is mounted. The handle I? has formed therein an elongated opening or window 22 for permitting the lamp 2| to illuminate the interior of the oven through the transparent sheets I 4. A thumb switch 23 is provided on the socket 20 for controlling the lamp 2I, said switch being operable in a slot 24 (see Fig. '7) which is provided therefor in one end portion of the handle IT.
A conductor 25 is provided for connecting the lamp 2i with a suitable source of current supply. The conductor 25 extends through the tubular trunnion 3, the groove 2 and the tubular arm I9 into the handle II where it is electrically connected with the socket 20, as shown to advantage in Fig. 6 of the drawings. A bushing 26 of insulating material is provided for the conductor 25 in the tubular trunnion 3. A split, expansible ring 21 is seated in a groove which is provided therefor in the outer end portion of the tubular trunnion 3 for retaining the bushing 26 in position therein. The reference numeral 28 designates a coil which encircles the conductor 25 where it leaves the outer end of the tubular trunnion 3.
g It is thought that the manner in which the door functions will be readily apparent from a consideration of the foregoing. The interior of the oven may be conveniently observed at any time through the transparent sheets 14 without the necessity of opening the door. To illuminate the interior of the oven it is only necessary to close the switch 23 on the handle I! for energizing the electric lamp 2!. The spaced transparent sheets I4 prevent the excessive loss of heat through the door. As hereinbefore stated, the temperature in the oven may be conveniently ascertained by simply observing the thermometer I2. Access to the interior of the hollow handle I'I may be had by removing a closure 29 (see Fig. 6) in one end of said handle.
It is believed that the'many advantages of an oven door constructed in accordance with the present invention will be readily understood and although a preferred embodiment of said door is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed What is claimed is:-
An oven door comprising an outer frame having a groove therein for the reception of a conductor Wire, a pair of spaced, transparent sheets mounted in said outer frame, an inner frame removably secured to the outer frame for retaining the transparent sheets in said outer frame, said inner frame covering the groove, a hollow handle mounted on the outer frame and having an opening therein adjacent said outer frame, an electric lamp mounted in the handle and adapted to illuminate the interior of an oven through said opening and the transparent sheets, said handle communicating with the groove for receiving the conductor wire therefrom.
