BROWN AND JOSEPH GARDNER, OF ST, LAURENT, QUEBEC, CANADA, ASSIGNORS TO THE GURNEY FOUNDRY COMPANY LIMITED, OF TORONTO, CANADA CONCEALED MANIFOLD AND VALVE MECHANISM FOR GAS RANGES Application filed November 5, 1928. Serial No. 317,272.
This invention relates to a construction of gas ranges whereby the manifold or gas distributing conduit which normally extends across the front of the burner compartment of a gas stove, and the valve mechanism for controlling the supply of gas to the burners are concealed from the view of the range.
The object of this invention is to provide such means for concealing the manifold and valve mechanism, while at the same time retaining many of the simple, readily accessible features of the standard type of exposed manifold and valves which are necessary to the convenient servicing and operation of the household gas cooking range.
Another object of this invention is to provide convenient means for lowering and raising the manifold and valves, and thus the burner, so that the range is adaptable for use with different qualities and pressures of gas which demand the positioning of the burner at different distances from the cooking top.
Still another object of this invention is the provision of means whereby the valves may be locked in their closed position, thus obviating the danger of having the valves accidentally opened.
lVe attain our objects by mounting the manifold beneath a front extension of the cooking top and threading the valve into the underside of the said manifold. A removable shield or plate is secured beneath the r extension of the cooking top and in front of the manifold and Valves, an opening in the said shield being provided through which the control handle of the valve extends. A projection is provided adjacent one end of the opening so that when the handle is swung to close the valve, the said handle drops over the projection and is thus locked in a closed position. The shield is also stepped-in along its lower part where the opening for the control handle is located so that the control handle extends beyond the plane of the front of the stepped-in portion but not beyond the plane of the front of the main part of said plate, thus reducing the possibility of accidentally persons using,
moving the control, handle when using the stove.
' In order to adapt the stove for var ing qualities and pressures of gas, a bloc is adapted to be inserted between the supporting ing, which is secured'to the under part of the extension of the COOkiIlg top, and the clamp, which is adapted to clamp the manifold to the supporting lug. The apertures leading through the front of the stove, through which pass the gas supply pipe leading to the manifold and the air mixer end of the burners, are elongated to accommodate them in either a raised or lowered position.
The construction is hereinafter more fully described and illustrated in the accompanying drawings in which F ig.vv 1 is a cross section, partly broken away, of the burner compartment;
Fig. 2 is a front elevation, partly broken away, of the burner compartment;
Fig. 3 is an end view, partly broken away, of the burner compartment;
Fig. 4 is a cross section, partly broken away, of the burner compartment showing the adjusting block in position;
Fig. 5 is a detail perspective View of the supporting clamp;
Fig. 6 is a detail block; and
Fig. 7 is a plan View, partly in section and partly broken away, showing the locking means.
In the drawings like numerals of reference indicate corresponding parts in the different figures.
The burner compartment comprises an end wall 1', a front wall 2, and the main cooking top 3. The front wall extends across the whole front of the burner compartment. Other parts of the burner compartment are not shown. The main cooking top extends beyond the front 2, as shown at 3. Beneath the front extension 3 supporting lugs 4 are provided. These lugs 4 are integral with or secured to the main cooking top. A semicircular channel 4 is formed in each supporting lug, these channels being adapted to receive the manifold or gas supply conduit 5.
The clamp 6 is adapted to be secured to the perspective view of the 2 lug 4 to clamp the manifold thereto. The
A valve 8, of known construction, has its intake pipe 9 threaded into the underside of the manifold 5. The outlet or burner feed pipe 10 passes from the valve back to an air mixer hood 11 on the burner 11. An air mixer facer 12, for regulating the air, is mounted in the hood. An arm 14 extends outwardly from the stem 13 of the valve 8 and a handle 15 is pivoted to the outer end of the arm 14 and adapted to be grasped by the user.
To conceal the manifold and valve mechanism above described, a shield or removable plate 16 is mountedbeneath the extension 3 of the main cooking top and in front of the manifold and valve. This plate 16 extends around the end of the burner compartment and is secured thereto by means of a screw 17 which is one of two screws or bolts, being the only means of support for the said late. This makes the plate easily removalile when access to the manifold or valve is required for purposes of repair or adjustment. The upper edge of the plate extends upward beneath the lower edge of the extension of the cooking top 3*, which is bent downward to form a rounded edge to the cooking top as shown in the drawings. The lower part 16 of the removable plate is stepped-in and does not extend around the end of the burner compartment as does the upper part, but abuts on the front 2 of the burner compartment, thus preventing the shield from pivoting on the screw 17 and dropping down.
An opening 18 is provided in the lower part 16 of the shield 16. This opening is horizontally elongated. The extension arm 14 of the valve stem 13 extends through the opening and the handle 15 drops down outside the plate 16 where it may be readily grasped by the user. The valve is operated by a horizontal movement of the handle 15 and the opening 18 is horizontally elongated to provide for such movement. The handle 15 does not,
- however, extend beyond the plane of the front of the main part 16 of the detachable plate, thus the danger of accidentally altering the position of the valve by the person using the stove is reduced. Aprojection 19 is formed on the stepped-in part 16 of the detachable plate below the opening 18 and adjacent one end thereof, so that when the valve is closed the handle may be dropped over the projection and thus locks the valvein a closed position.
When the range is used for gas of high pressure or inferior burning qualities, it may be desirable to lower the burner 11relative to the cooking top 3. To effect this, a block 20 is provided. This block is adapted to be inserted between the supporting lug 4 and the clamp 6 and is provided with a circular groove 20 to receive the manifold, a bore 20 through which the connecting screw 7 is adapted to pass, and a triangular lug 20 adapted to engage-the notch 4 in the lug 4.
A triangular notch 20 is formed in the lower side of the block and is adapted to engage the lug 6 on the clamp 6. When the manifold is thus lowered, a removable plate 16 of greater depth is used to conceal the manifold and valve mechanism. The openings 21 and 22, through which the air mixer end of the burner 11 and the gas supply pipe 23 pass respectively through the burner compartment front 2, are elongated so that they are adapted to receive the said air mixer end of the burner and gas supply pipe respectively in either their raised or lowered positions.
Although we have described our construction as applied only to one burner, it is understood that in practice there may be any number of burners depending upon the size of the range to which the construction is applied.
It will be seen from the constructions above described that we have devised a concealed manifold which is neat and attractive in ap- 10o pearance, easily accessible for urposes of adjustment or repair, and which is safe and convenient for use.
