SAFETY GUARD FOR GAS RANGE ON-AND-OFF VALVES Filed March 9, 1960 IN V EN TOR.

MORRIS FOX ATTORNEY amazes Patented July 10, 1952 3,043,289 SAFETY GUARD F011 GAS RANGE N-AND0FF VES This invention relates to protective guards or covers for gas ranges and the like, and an important object of the invention is the provision of a readily attachable and removable cover or guard which, when in position, completely conceals the petcocks of the range and maintains them inaccessible to small children. Thus inadvertent or playful turning on of unlit gas jets with the consequent undesirable effects, is avoided.

Another object of the invention is the provision of a guard such as mentioned above, which embodies novel and useful structural improvements for releasably maintaining the guard in place against possible efforts of small children to detach or move it while permitting a grown person to remove the guard at will. Thus, for example, when a home is being visited by a small child the guard may be mounted in place and left there until the child has departed. I

Still another object of the invention is the provision of a gas jet petcock or valve guard for gas ranges and the like wherein the guard is a complete integral unit including the means for attaching it to the range, and

whereby no alteration, defacement or any work of any kind is required to be done to or on the range. Thus after the guard has been removed the range has identically the same appearance as before it was applied.

A further object of the invention is the provision of a guard for the purpose mentioned wherein the means for attaching it to the range includes magnets which grip the ferrous housing of the range.

The above as well as additional objects will be clarified in the following description wherein reference numerals refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended primarily for the purpose of illustration and that it is therefore neither desired nor intended to limit the invention necessarily to any or all of the exact details shown or described except insofar as they may be deemed essential to the invention.

Referring briefly to the drawing,

FIG. 1 is a fragmentary perspective view of a gas range having the protective guard of the present invention attached thereto.

FIG. 2 is partly a top plan view of FIG. 1 and partly a sectional view taken on the line 22 of FIG. 1.

FIG. 3 is a rear elevational view of the guard per se.

FIG. 4 is an enlarged fragmentary sectional view taken on the line 4-4 of FIG. 3.

FIG. 5 is a fragmentary enlarged rear elevational view.

Referring in detail to the drawing, the numeral indicates a gas range or the like having, in the usual manner, a row of valves, petcocks or the like 12 positioned at or near the upper edge of the front wall 11 and adapted to be turned on and off for ignition of the burners 13.

The present invention utilizes a housing 14 which is I elongated sufi'iciently to exceed the distance between the outermost valves 12. The housing is unitary and embraces the front wall 15, the bottom wall 16, the top wall 17 and the end Walls 18; the back of the housing is open. The housing is made of a light weight material. In the illustration this material is assumed to be aluminum, in which case either narrow openings, in suitable positions as indicated at 19, are provided in the top wall 17 to serve as windows, or similar suitable openings covered with a transparent fireproof material, such as, for example, mica, not shown, are provided. The windows serve to give visual access to the valves 12. The housing may also be constructed of any suitable synthetic plastic material, not shown, of a transparent'type, in which case windows would not be required.

At each end of the housing 14 a magnet 20 is secured against the inside of the end wall 18 in a suitable manner. One example of such securement is illustrated, in the form of a bolt or rivet 21 passed through the magnet and the end wall. The rear contact surface or surfaces 20a of the magnets is flator, at least, such surfaces lie in the plane of the rear edges of the top and bottom walls.

Secured against the inner surface of each magnet 20 is one web 22 of an angle-shaped ferrous member or attachment 23, the other web 24 having its flat outer surface 25 lying flush with and in the plane of the magnet surface 20a. The angle iron 23 thus increases the magnetic contact area of the magnet 20 and serves an additional purpose clarified below.

The guard, as far as thus described above, is obviously attachable to the wall 11 about the valves 12, as illustrated in FIG. 2, with the magnets holding the housing against the ferrous front wall of the range. The angles 23 may of course also be magnetized, but even if they are not there will be a magnetic flux issuing into the angles from the magnets thus increasing the magnetic contact area.

The exterior surfaces of such ranges are usually coated with an enamel or other hard and smooth finish, upon which the magnets 2% may be subject to sliding movement in case of accidental impact thereagainst. In order to minimize such possible sliding, the following additional improvements are provided. At each end of the housing a moulding-like strip or' flange of soft rubber 26 is mounted adjacent the rear end of each magnet 20 in vertical position with the rear edge 27 protruding somewhat beyond the said plane through the rear edges of the top and bottom walls. Additionally, the edge 27 of the strip is provided with a longitudinal groove 28. In order to accommodate the strips 26 the rear portions of the end walls 18 are deformed outward to provide them with flared extensions or flanges 28a within which the strips register. The strips 26 may readily be cemented or otherwise fixed within these flanges. The vertical rear edges 29 of the flanges 28a also lie in the same plane as the rear edges of the top and bottom walls 17 and 16, respectively.

Upon applying the housing 14 against the range wall 11 in the manner illustrated in FIGS. 1 and 2, the magnetic contact surfaces of the magnets 22 and, if the angles 23 are also of ferrous material, the webs 24-, will firmly be held against the wall 11. During this procedure the ridges 30 of the strips 26, which define the groove 28, will be compressed and spread, thus providing a nonslip cushion surface which is also in contact with the surface 11. In FIG. 4 the ridges 30 are shown exaggerated in size. Thus, when the guard is mounted in place any force tending to slide it on thesurface is resisted by the cushioning soft rubber strips 26.

The webs 24 of the angle irons 23 also serve the following function. It is to be noted that each valve or petcock 12 has its rotatable handle or hand grip positioned outward from, that is, forward of, the surface 11. In the case illustrated in FIG. 2, each valve is shown spaced'forward of a fixed boss 31. It is apparent that in the event that the housing 14 is accidentally bumped or pushed horizontally or nearly horizontally, the edge of the web 24 will meet the boss 31 and stop further movement of the housing before the adjacent web 22 or magnet 20 strikes the valve. Thus accidental turning on or contact the range Wall. 7

range When-the range is not in use, it is a simple and easy mattergfor a grown person or one old enough to bear responsibility, that is, all persons other than irresponsible small children, to pull the guard outward and out of the way to gain access to the gas valves.

Itis desirable that the housing 14 be made of any suitable light weight material, as is obvious, and any kind of windows may or may not be provided, in any position or positions in the housing, as a matter of choice.

It is to be notedthat the rear surfaces 20a of the magnets 2%), as well as the surfaces/25 of the extensions 24, may be positioned rearward of the plane through the rear edges of the housing walls, or even slightly forward of the said plane. In the latter case, however, the magnetic attraction between the Wall '11 and the magnets would be of a lesser degree than when th magnets actually The invention having thus been described, what is claimed and desired to be secured by Letters Patent is as follows:
