DISAPPEARING COOKING TOP FOR TABLE STOVES Filed Feb. 26,1931 2 Sheets-Sheet 2 Patented June 7, 1932 UNITED STATES ALVIN G. ARNDT,

PATENT OFFICE PANY, OF OWOSSO, MICHIGAN, A. CORPORATION OF MICHIGAN DISAPPEARING COOKING TOP FOR TABLE STOVES Application filed February 26, 1931.

This invention is a novel improvement in disappearing cooking tops for table stoves, said stoves having portions of their top surfaces provided with fixed permanent covers, also other portions provided with hinged covers below which are mounted the cooking tops of the stoves which carry the gas or other burners, the hinged covers normally concealing the cooking tops when the hinged covers are lowered.

The principal object. of the invention is to provide means whereby when the hinged cover of a table stove is swung upwardly to permit use of the cooking top the latter will be automatically raised flush with the perma nent cover so that cooking utensils may be slidably moved over from the permanent cover to the cooking top without having to raise or lower such utensils; and whereby when the hinged top is swung down to conceal the cooking top said means will automatically lower the cooking top sufficiently below the hinged cover so that the latter will lie flush with the permanent cover.

Other minor objects of the invention will be hereinafter set forth.

I will explain the invention with reference to the accompanying drawings which illustrate one practical embodiment thereof to enable others to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawings:

Fig. 1 is a perspective view of a table stove embodying my invention and showing the hinged cover for the cooking top swung upwardly into open position.

' Fig. 2 is a vertical section on the line 2-2, Fig. 1.

Fig. 3 is a vertical section similar to Fig. 2 but showing the hinged cover in closed position.

Fig. 4 is a horizontal section on the line 44, Fig. 3.

Fig. 5 is an enlarged section on the line 55, Fig. 2.

My invention is illustrated in the drawings in connection with a table stove of the gasa range type, having substantially half of its Serial No. 518,542.

upper surface provided with a permanent fixed cover 2, and the other half provided with a swingable cover 3 hinged to the rear of the stove and adapted to be swung from lowered or horizontal position, flush with the fixed cover 2, into substantially vertical position shown in Figs. 1 and 2. The cooking top 4, which referably comprises an iron casting of slig tly less area than the hinged cover 3, is disposed immediately under and in the path of swing of the hinged cover 3, and the cooking top 4 is supported at each side upon wedge shaped blocks 5a carried by elevating bars 5, slidably mounted upon inwardly extending flanges 104 on the side frames 1, said elevating bars 5 being horizontally shifted through suitable linkage by and with the opening and closing of the hinged cover 3. Preferably the gas burners 4av are supported in any suitable manner below openings 46 in the cooking top 4.

Bars 5 carry adjacent their forward and.

rear ends inclined wedging surfaces 5a adapted to co-act with complementary inclined surfaces on the undersides of the cooking top 4 whereby as the elevating bars 5 are slid on their supporting flanges 1a the cooking top 4 will be correspondingly raised or lowered, the inclination of the inclined surfaces 51 and 40 being such that when the bars 5 are fully retracted towards the back of the stove, i. e. when the hinged cover 3 is in lowered position, the upper surface of the cooking top .4 will lie below the undersurface of the hinged cover 3; and when the sliding bars 5 are moved outwardly towards the front of the stove, i. e. when hinged cover 3 is fully raised, the upper surface of the cooking top 4 will lie flush with the upper surface of the fixed cover 2 of the stove.

Suitable flexible connections 6 are provided between the gas manifold 7 (Fig. 4)- and the burner inlets whereby the raising and lowering of the cooking top 4 will not affect the feeding of gas from the manifold to the burners.

The hinged cover 3 is hingedly mounted as at 3a to the back frame of the stove and carries adjacent its rear edge a back guard plate 3?) extending normal to the cover 3 and adaptvating bars will be pushed forwardly or rearwardly, as the case may be, on their supporting flanges 1a.

The operation is as follows: When the stove is not in use the hinged cover 3 should be lowered as in Fi 3. The elevating bars 5 will then be shi ted to the extreme rear limits of their travel and the cooking top 4 I will be automatically lowered into position shown in Fig. 3 so as to be completely covered by the hinged cover 3. When it is desired to use the stove the hinged cover 3 is swung upwardly as shown in Figs. 1 and 2 and in so doing the elevating bars 5 will be moved to their extreme forward limits through the action of arms 9 and links 10, and the cooking top 4 will then be automatically raised, as in Fig. 2, flush with the permanent cover 2, whereby when the stove is in use the surface of the cooking top 4 will be level with the permanent cover 2 so that cooking utensils may be'slid from one to the other without raising or lowering such utensils.

' I do not limit my invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.

I claim:

1. In a stove, a cooking top carrying the heating elements a pivoted cover for concealing the cooking top when the cover is closed; and cam means automatically operated by the cover for raising the cooking top into the plane of the top of the stove when the cover is opened; said means automatically lowering the cooking top when the cover is lowered.

2. In a stove, a cooking top carrying the heating elements; a pivoted cover for concealing the cooking top when the cover is closed; slide bars supporting the cooking top and means operated by the cover for automatically shifting the bars to raise the cooking top flush with the top of the stove when the cover is opened, said means automaticaL ly lowering the cooking top below the cover when the cover is closed.

3! In a stove having a portion of its upper surface provided with a fixed cover; acooking top for the other portion, said cooking top carrying the heating elements; a hinged cover adapted to be flush with the fixed cover and for concealing the cooking top when the hinged cover is closed; slide bars supporting the cooking top and means connecting the hinged cover and bars whereby when the hinged cover is raised the cooking top will be automatically elevated flush with the fixed cover, and when the hinged cover is lowered the cooking top will be automatically depressed below the hinged cover.

4. In a stove having'a fixed cover over a portion of its upper surface; a hinged cover over the remaining portion; a cooking top carrying the heating elements normally concealed by the hinged cover when closed; and cam means automatically operated by the hinged cover whereby when the latter is raised the cooking top will be elevated flush with the fixed cover, and when the hinged cover is lowered the cooking top will be lowered below the hinged cover.

5. In a stove having a fixed cover over a portion of itsupper surface, a hinged cover over the remaining portion; a cooking top carrying the heating elements disposed under the hinged cover; cam bars slidably mounted in the stove for supporting the cooking top; and means automatit ally operated by the hinged cover whereby when the latter is raised the bars will be shifted to elevate the cooking top flush with the fixed cover, and when the hinged cover is'lowered the cooking top will be lowered below the hinged cover.
