GAS RANGE.

Application filed February 2, 1928. Serial No. 251,338.

' This invention relates to improvements in gas'ranges and more particularly to a gas range having a'closed front under the cooking top behind which is concealed the gas 5- manifold and gas cocks for supplying gas to the cooking topburners.

- The primary object of the invention is the provision of a gas stove of the type described which is of an improved appearance in that it presents a smooth and neat front.

' Another object ofthe invention is the provision of a gas stove of the character described having at its front below the cooking to operating handles conveniently l5 placed or the operation of the gas cooks for the burners. a

Another and further object of the invention is the provision of a gas stove of. the character described wherein theair and gas intake ends for the cooking top burners project through the end of the burner box and operating handles for the gas cocks are carried to a'point at the front of the range below the cooking top so as to be conveniently placed 26 for the hand of the operator of the stove.

A still further object of the invention is the provision of a stove of the character de scribed whic is of a construction whereby it is applicable to standard and approved'stove 30' parts such as top burners, top grates, gas

cocks, and manifold supply pipes.

Another and further object of the invention is the provision of a construction wherein the products of combustion from the top burners can not enter the mixing tubes and thus disturb the admission of primary air for the combustion and thereby impair the operation and combustion of the burners.

A still further object of the invention is cocks are located in such a position that adjustment or removal of them can be easily made by the easy and ready removal of the end shelf of thecooking top.

A still further object of the invention is the provision of a construction wherein the gas cock is so positioned as to not become overheated which tends to destroy the lubricant in the valves and make them hard to operate.

A still further object of the invention is the provision of a gas stove of the character described which is cheap and simple of manufacture, highly pleasing. in appearance and efficient in operation.

the provision of a construction wherein gas- Referring now to the drawings: Figure, 1 1s a view in front elevation of a complete gas range built in accordance with my invention.

Figure 2 is a horizontal sectional view showing the arrangement of the burners, gas cocks and gas cock operating handles.

Figure 3 is a detailed View, partially in vertical section, of one of the burners and the Figure 6 is a top plan view of the cooking top of the stove appearing in Figure 4.

Figure 7 is an enlarged detailed view, partially in vertical section, showing the handle for operating'one of the gas cooks for one of the burners of the modified form of the invention.

Referring now to the drawings, particularly Figures 1 to 3 inclusive, the entire gas range is designatel by A and with the exception of the concealed manifold and gas cooks for the cooking top is more or less of conventional form in that there are the usual legs 10 supporting a. stove base 11 upon one end of which is mounted the oven ,12 and broiling oven 13. The stove shown in the drawings is what is known as a. right-hand oven stove.

Gas is supplied to the two ovens by a gas conduit 14 and a thermostatic control for the oven burners is provided at 15.

The cooking top of-the range is at the left side or end of the frame, being designated by the numeral 10 and this cooking top can be provided wlth a solid or grate top as the desire may be. A common form of gas range construction is present in that there is a splasher back or plate 17 behind the cooking top andat the upper end of the sp-lasher there is provided a shelf 18.

The space beneath the cooking top is closed in entirely by the stove back 19,, end 20 and front 21. The front 21 is provided with an etlongation 22 which extends beyond the end .20 of the range'adistance equal to the width of the cooking top shelf 23 which shelf is removable as is a common construction in respect to gas ranges.

'By reference to Figure 2 of the drawings it will be seen that there are four burners in the four corners of the cooking top. The burners 24 and 25 are front burners and 26 and 27 the rear burners. These burners are provided with gas inlet manifolds 28 carrying at their ends mixing bells 29 which extend through the end 'wall 20 of the range rather than through the front wall of the range is a common practice. The burners are supported in place by suitable longitudinal bars 30 which extend lengthwise of the range in the burner box beneath the cooking top.

The gas supply conduit for the cooking top burners is designated at 31 and makes in at the rear of the stove and extends along the end 20 thereof beneath the cooking top shelf 23 and is supported in spaced parallel relation to the end 20 of the range. The burner cocks or valves 32 have one end threaded into the conduit 31' while their other ends are provided with jets 33 which deliver gas into the mixing bells 29of the stove burner manifolds.

By reference to the drawings it will be seen that from the front of the stove the gas conduit 31, the gas cocks 32, and the extending ends of the bells 29 are hidden from sight by the extending end portion 22 of the stove front.

It is essential that a convenient means of operation of the gas cocks be provided and this is present at t e front of the stove in the form of four handles 34, one being for the control of each of the burners. These handies 34 are rotatable and each of them is provided with an elongated shaft or stem 35 extending intothe burner box beneath the cooking top where they have connection :with the short cranks 36 which are fastenedto ro tate with the stems. Each of the gas cocks .is provided with an arm 37 and pivotal bars 38 pivotally attached to the arms 37 as at 39 and pivotallymounted at 40 in the crank arms 36 complete an operative connection between the valves 32 and the valve operating handles 34 at the front of the range.

With the construction just described it i will be seen that by oscillating the handles 34 the stove valves can be opened or closed as desired.

No particular description of the valves 32 has been given as it is thought it will be readily apparent that they are of a common form of rotary plug valve construction.

The solid front 21 below the cooking top is provided in its bottom with a sliding drawer 41 wherein utensils may be stored or kept while intermediate the drawer and the cock operating handles 34 is a sliding dirt catching tray 42 which may be periodically removed for cleaning and guards the drawer 41 from dirt which might fall through the cooking top or from the burners.

Referring now to the modified form of the invention appearing in Figures 4 to 7 of the drawings it will be seen that the stove proper is lesignated by B and is of that type known as a left hand oven construction.

In these figures of the drawing the cooking top, splasher back, splasher back shelf, stove legs, base, cooking and broilingovens, gas delivery pipe to the ovens, thermostat utensil drawer and sliding dirt tray are given the same numerals as has been given to them in those figures of the drawings wherein the preferred form of the invention is illustrated.

' In this form of theinvention the cooking top shown is of the open type being provided with grids 43 beneath which are positioned the two front burners 44 and the two rear burners 45 having gas manifolds 46 terminating in the mixing bells 47 which extend slightly beyond the range end 48.

As was the case in respect to the preferred form of the invention the range from 49 beneath the cooking top, is of a solid construction and has an extending end portion 50 beyond the end 48 of the range and that the removable shelf 51 of the-cooking top is positioned above this extending portion of the range front. 1

The space beneath the cooking top is closed in completely by the range front 49, end 48 and the rear wall 52 of the range.

The gas delivery pipe 53 for the cooking top burners parallels the back of the range and extends along the end 48 of the range in spaced parallel relation thereto. A plurality of gas cocks 54, one for each burner, are provided for deliverin gas from theconduit 53 into the mixing ells 47 of the stove burners. These gas cocks are of a common rotary plug type and by reference to Figure 7 of the drawings it will be seen that they have I extending arms 55 to which the rods 56 are pivotally connected as at 57. These rods extenddownwardly and forwardly to a point just-in back of the extension portion 50 of the range front 49. Arranged in a vertical row down the extension portion 50 of the stove front are four handles 58 attached by screws 59 to stub shafts 60 which are mounted'for oscillation in the bosses 61 provided on the inner face of the extension portion 50. Each of the stub shafts is provided with a pin 62 which prevents them from being pulled outwardly through their supporting openings. I

The lower ends of the rods 56 are provided with forks 63 pivotally attached to the rod as at 64 and these forks are in turn provided with ins 65 extending through the slotted ball s apedends 66 of the stub shafts ofl whereby a universal joint is provided between the lower ends of the rods 56 and the stub shafts 60 of the operating handles 58.

At the front of the range adjacent the cock or valve operating handles 58 is a button 67 which operates a lighter for the burners of the cooking top. The lighter valve operated by the button 67' is of a standard construction in that it is spring seated and a pull on the button 67 opens the valve and allows gas to flow to the pilot light for the purpose of causing a larger flame in the pilot for lighting the main cooking top burner.

From the foregoing it 'willbe seen that in to keep the stove clean and the operation of the stove is excellent by reason of the -fact that the bells at the ends of the burner mixing tubes receive their air exteriorly of the burner chamber which makes fora much better combustion atthe burners. I

It will be understood that should this stove be provided with a closed cooking top it would be necessary to provide air inlet holes or openings in the end 20 of the burner box-. Having thus described my invention What I claim and desire'to secureby Letters Patent is:
