UNITED sTATEs OBBIN HOFFERBEBT, F BEAVER DAM, WISCONSIN, .ASSIGNOB TO MALLEABLE RANGE COMPANY, .A CORPORATION OF WISCONSIN P AT T orricl iRoN RANGE Application filed April 9,

This invention relates to improvementsin ranges.

The principal object of theY invention is to provide a range having two similar doors in the front., one for the oven and the other to conceal the service drawer, drip pan, and switch controls if the range be electric, or the gas valve handles if the invention is embodied in a gas range, this latter door being hinged preferably at the bottom and arranged to slide into the range structure during the use of the range. l

In ranges finished in enamel for instance,

it is necessary that the door in being slid to and from position within the range structure be prevented from contact with adjacent portions of the range in order that the nish will not be scratched or otherwise marred. Another object of the invention, therefore, 1s

to provide a guide mechanism for the slidingv door which will retain the door in spaced relation with respect to adjacent portions of the range structure while the door 1s wlthin the structure, or is being moved to, or from, such position.

Another object of the invention 1s to provide cushioning mechanism for the door -to prevent damage thereto in case .1t should be permitted to fall to horizontal position, such `mechanism also being adjustable to re-aline the door horizontally should the hinge members become bent during use.

Other objects relate to various features of construction and arrangementof parts which will be apparent from a consideration of the following specification and accompanying drawings wherein Fig. 1 is a perspective view of an electric range of the buffet or cabinet type, embodyingthe present improvements.

Fig. 2 is a broken perspective view 1llustrating the slidable door moved tothe inner position to provide access to electric switches and service drawer.

Fig. 3 is a vertical transversey sectional view through the range showing the slidable door in partially opened position, the dotted lines indicating the horizontal position of the door.

, 1931. Serial No. 528,889.

Fig. 4 is a vertical sectional view taken on lines 4 4 of F ig.l 3.

the sliding door and associated guide and adjustable cushioning mechanism.

1n the drawings the range is indicated Fig. 5 is a detached perspective View of generally by the numeral 10 and in the form Y shown is of the so-called buifet type having an oven door 11 vat the right hand end of the range which maybe hinged at the bottom by any approved means. 'At the other end of the range a door 12 is provided which is` similar in appearance to the door 11. The

door 12 when closed, as shown in Fig. 1, conceals the switch panel 13, utility drawer 14, and also a drip pan, not shown. The switch controls 15 may bearranged for controlling the" current to the hot plates 16, While the control 17"Te'gulates current to the heating4 elements in the oven. Asshown in Fig. 2, the door 12 has been -slid into a space or chamber 18 provided in the range structure, thus providing convenient access to the switch controls and the drawer 14. In sliding the door 12 to and from this inner'position it is desirable that the door be held out of Contact with adjacent. portions of the range structure to avoid marring the enamelled surface of the door. Tovaccomplish this result suitable track members 19 are provided in the chamber 18 along which is arranged to slide a guide member 20 which may be formed of sheet metal. lVelded or otherwise secured to the vertical ends-of the guide member 20 are a pair of forwardly projecting strap or. hinge members 21,' which have their forward portions preferably offset inwardly from the vertical plane of the rear portions thereof as indicated in Fig. 5. The door 12 has ears 22 weldedor otherwise secured thereto, which ears are preferably pivoted, as at 23, to, the cooperating hinge` members l.21. As indicated in Figs. 2, 3 and 5 the door 12 can be lowered to a hori- T zontal position, but further downward move- 9 face of the inner track members, although the central embossed portion 12a of the door may extend below the plane of said tracks.

While the door is in this horizontal position it may be slid with the guide member into the chamber 18 to the position shown in Fig. 2. During this movement the door is retained by gravity in parallel relation with the guide member 20 and is spaced from contact with any adjacent portions of the range structure which might mar its outer enamelled surface. Y

When it is desired to close the door it. is first pulled outwardly in a horizontal direction and then swung upwardly about the pivots 28 to the position shown in Fig. 1. The outward sliding movement of the door is arrested by stops 25 carried by the slide 2O which contact with member 26 secured to the upper forward portion of the chamber 18.

In use the door 12 may frequently be dropped accidentally to horizontal position, or while in extended horizontal position may be used asa support or shelf for heavy pans or other utensils. Such abuse might, of course, cause the enamel to crack or spring the hinge members 21, 22 or bend the flange 24 so the door will not be arrested in hori zontal position, in.which event it will be likely to have its outer surface marred while being slidl into or from 'the positionwithin the range structure. To avoid the result of such mis-use, I have provided a cushioning mechanism which will absorb the shock of the falling door and thus prevent damage to the hinge members or iange 24. This mechanism, in the embodiment illustrated, pref-Y erably comprises two resilient or spring straps 27 which are welded or otherwise secured at their rear ends 28 to the guide 20. Their forward ends are spaced above vthe guide, as shown in Figy, and are provided with apertures through which extend bolts having wing nuts 30 on their lower ends.V

0 before the door has reached the horizontal 55 crack the enamel or bend the hinge members position. The stresses and vibrations which would bev imparted to the door upon acci-f andthe lower portion of the door. By adjusting the wing nuts 30, the tension of the springs 32 can be varied as desired. Should the hinge members 21, 22 or the iange 24 be` come bent through accident or mis-use so the door is not stopped normally in horizontal position,'the tension of the springs 32 may be increased suiiciently so the members 27 will hold the door in the proper osition.

lVhile I have shown and descri d one embodiment of the invention for the purpose of illustration, I do not wish to be restricted specifically thereto except as so limited by the appended claims.

What I claim is:
