2' Claims.

This invention relates to a simplified safety control device for the burner valves of gas cookmg stoves or gas ranges having their front and top surfaces lying in right-angular planes and valves and to provide an overhanging plate at the front portion of the cover and in right-angular relation with the cover, for concealing the burner valves and prevent anyburner valve from being open when the cover is infull closed posilOIl.

Another object of this invention is to provide a control bar attached to the cover and being slidable relative to the under side of the cover, the cover being hinged at the rear of the gas stove to permit the cover and control bar to be swung upwardly as a unit out of the way of both the valves and burners and to securea substantially vertical reciprocating movement of the control bar when the bar comes in contact with a valve handle in open position.

Another object of this invention is to provide ears rojecting rearwardly of the control bar and engageable with the valve stems, and to provide means for engaging the slidablecontrolbar for manually moving the barhorizontally relative to the cover after it has been swung down to closed position and thereby complete the closing of the valves and simultaneousl causeinterlocking engagement of the cover with the valve stems.

With the above and other objects'in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claims. which form part of this specification. A

Reference will now be had to the drawing, wherein like numerals of reference designate correspondin parts throughout the several views, in which:

Figure 1 is a perspective view of a gas range having a cover in which my control mechanism is incorporated, the cover being in open position.

Figure 2 is a view similar to Figure 1, but showing the cover in closed position. V

Figure 3 is a fragmentary cross-sectional view, the section being taken as on line 3-3 in Figure 2, and showing two valve handles in open posi- 131011.

Figure 4 is a fragmentary cross-sectional view, similar to Figure 3, and shows a valve handle in partl closed position. I

Figure 5 is a fragmentary cross-sectional view, the section being taken as on line 5-5 in Figure 3.

Figure 6 is a fragmentary cross-sectional view, similar to Figures 3 and 4', and shows a valve handle in closed position.

In the illustrated embodiment of the invention, the numeral I0 indicates a gas range or gas cooking stove of the cabinet type, comprising burners II and burner control valves I2,

The gas range In is also provided with a cover I3 which is hinged on a pin I4 at the rear of the gas range. The valves I2 have operating handles I5 by means of which the valve stems are given ninety degree movements.

For the purposes of this invention the cover I3 is made long enough tooverlap the valves I2. At the front portion of the cover there has been provided an overhanging plate I6 which extends downwardly sufiiciently to conceal the valve handles I5.

Figure 3 is a cross-sectional view, the section being taken ason line 33 in Figure 1, and shows ,a control bar or locking bar I8 in fragmentary' form. The control bar I8 is slidably mounted in concealed relation. rearward of the overhanging front plate I6. Brackets I9 fixed to the lower surface of the cover I3 provide bearings at both ends of 'the control bar I8 whereby thecontroI bar I8 is attached to the cover I3.

The control bar is positioned in vertically superposed relation directly over thevalve handles I5 when thejcoverl3 is in lowered positionover the gas range I0". The control bar has openings 20, one for each valve handle. Onesurface portion 2| of eachopening 2:] is cam shaped and positioned so as tocontact a valve handle when the "handleis horizontally positioned, that is, when the valve is in open position. a Y

When the user swings the cover downwardly, the cam surface 2I contacts the horizontally positioned valve handle I5 and this contacting relation remains during the continuing downward movement of the cover. At the lowest downward position of the cover, the valve handle I5 is not at its desired ninety degree position because of the diminished leverage at the said lowest position.

For the pu p se of completing the movement of th valve handle to full ninety degree valve closing position, the user applies a sideways pressure against button 22 positioned in front of the plate I6 and having a stem 23 connected to the control bar 18. The stem 23 is slidably mounted in an elon a ed sl t 24 in the p ate .46, the slot being srtfliciently long to permit the control bar to move horizontally and to move the valve handle l to full vertical closing position.

A latch bolt 25 is pivotally mounted one pin 26 passing through a forked end"?! of the control bar l8. serves for engagement with an angular topthfijl on the latch bolt 25. horizontal movement of the control bar 1-8, a spring 3| secured to the plate "5 presses-the dutch .bolt 25 into engagement with the stop 28. The

control bar is then held in fixed position horizontally and the valve handles are then held in fully closed position.

=It-is-to be noted that ears 32, integral with \the control bar 4 8, are provided rearward of the control bar. The ears project rearwardly of the control bar a distance sufficient to "permit :the ears to clear the valve handles and to move under the valve stems 33. In this position, the ears are bet-ween the valve handles and the casing of the gas range. "The ears have upper horizontal surface which, when in engagement with the undersuriaces of the valve stems, lock the cover I3 to the gas range [0 when the cover is in closed position and-the horizontal movement of the control-bar-is completed.

It will thus be noted that there has been provided aun-ita-ry cover and built-in mechanism for closing the valves on gas ranges and that this unitary device is adapted for installation as an attachment to gas ranges already built.

As a safety feature against :the manipulationof the mechanism by children, there has :been'l'ncorporated two movements in addition to the :usual -vertical swinging movement of :the cover. It is first necessary to use the right hand- 12p release thela'tch bolt 25 andto :usexthe left hand to grasp :the button 22 and move the control rbar 4-8 to the left to release the valve stems from the cover be- :iore it is po si le o movehe cov r upwar y, away from the gas range. This two hand-opera- :tional requiremen p ovides a saiety f at against the turningonef the gas by children and preventszaccidents. Y

From the above it will be seen that the gist of this invention isto proyide a uniterycover andhurnercontrol tattachmentwhichmey e attachod as a unit-on new o .onexist ng easttoves and su ported in its -.entirety externally r the stoves.

The demand .of ga .users is 0 ga st e ing handles, themuvements of wh cha p r \totthe Imnt facecr parallel to the top face v01. the

A stop 28 is secured to the cover I 3 and pon compl tion of the V gas stove, so that their movements are solely between full vertical and full horizontal positions and so that mistakes can not be made in their operation, that is, movements wherein the handles are either perpendicular or parallel to one of these surfaces, as distinguished from in-between angular positions.

In accordance with the patent statutes I have vdescribed and illustrated the preferred embodi- -ments :of myinvention, but it will be understood that various changes and modifications can be :made therein without departing from the spirit of theinvention as defined by the appended claims.
