April 28, 1931. G. E. PICKUP SOLID FUEL STOVE Filed June 3, 1929 Patented Apr. 28, 1931 UNITED STATES Paras OFFICE GEORGE n'moxur, or NEWARK, OHIO, ASSIGNOB r20 THE WEI-lIRLE COMPANY, or

. NEWARK, OHIO, A CORPORATION or 01110 SOLID-FUEL STOVE Application filed. June 3, 1929. Serial No. 367,848.

The invention relates generally to solid fuel burning stoves, and more particularly to a new and improved hinge support and counterbalancing means for the oven door ofa stove adapted to burn coal, wood, coke,

peat, etc.

Stoves or ranges adapted to burn solid fuel are commonly constructed with a firebox at one side and extending substantially the full depth of the oven, with the space immediately over the firebox and oven constituting a combustion chamber. The side of the stove opposite the firebox is customarily provided with a water lagging or reservoir. This standard arrangement has resulted from considerations of economy of space, accessibility, appearance and ease of operation.

The oven is provided with a door pivotally supported on hinges on the front of the stove. Counter-balancing means is commonly employed, and usually consists of torsion springs coiled about the hinge members. This construction is exceedingly bulky and mars the appearance of the front of the range.

The primary object of the inventionis to provide a novel hinge support for the oven door, all parts of which are located rearwardly of the front surface of the stove.

Still another object of the invention is to provide a new and improved hinge support for the oven door of a solid fuel burning stove and counter-balancing means therefor which is located at the side of the oven remote from the fire box to protect same from the heat, and which is concealed to improve the ap earance and general contour of the stove.

' nother object of the invention is to provide novel counter-balancing means for the oven door which is so located that it will be readily accessible for purposes of replacement or repair.

Further objects and advantages of the invention will be understood from the followingdetailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a view in front elevation of a stove embodying a preferred form of the invention.

50 Fig. 2 is a fragmentary horizontal sectional View taken along the line 22 of Fig. 1.

Fig. 3 is a'fragmentary view showing the right hand trunnion and the counter-balancing means in elevation.

Fig. 4 is a fragmentary side elevation of the stove illustrated in Fig. 1.

The invention in certain of its aspects is applicable to various types of stoves, but is particularly advantageous in stoves burning solid fuels, such as coal, coke, peat, or Wood, and hence is illustrated in connection with a stove of this character.

Referring more particularly to the drawings, the stove illustrated comprises a base 5' 10 having a plurality of supporting legs 11, and a superstructure mounted thereon. The structure forms an oven 12 substantially over the center of the base 10, a fire box 13 adjacent one side of the oven, and a flue space 7 leading from the box over the oven. The upper-wall of the flue spacev constitutes a suitable top hot plate or'cooking surface 11.

On the side of the oven 12 opposite the fire box is optionally mounted a water reservoir 16, the upper surface 17 of which is substantially flush with the top surface 14 of the stove, and adapted to constitute an extension thereof providing a side shelf for utensils. The fire box and oven are provided respecg tively with hinged doors 18 and 19. The door 18 preferably is mounted to swing about a vertical axis substantially along its left edge as viewed in Fig. 1. Any suitable form of hinge support may be utilized for the fire 35 box door 18, and in the present instance a pintle and gudgeon type is employed for the reason that its parts may be so arranged as to be within the stove when the door is in its closed position, thus not detracting from the appearance of the front of the range.

The oven 12 has suitableside walls 20 and 21, the former being adjacent the fire box. An outer wall 22 is provided in spaced relation to the wall 21 to improve the heat re- .95 taining properties of the oven. Secured to the front of the oven is a suitable door frame 23 defining a flanged opening 24 in which the door 19 is adapted to be located when closed. The side of'the frame 23 remote from the 0 fire box 13 is channel-shaped in cross-section, having legs 25 and 26 secured respectively to the walls 21 and 22.

The door 19 is adapted to swing open and closed about an axis substantially coincident with its bottom margin. To this end, the door is provided with trunnions '27 and 28 on opposite ends, the trunnion 27 being journal d in the leftWa-ll of the frame 23 and the trunnion 28 being journaled ill the legs 25 and 26 of the right wall of the frame and extending therethrough. The trunnions are secured as by means of bolts 29 in recesses or insets 50 formed in opposite ends Qfthe lower marginal edge wall of the door.

"Thus,tlie pivotal mounting for the door is not exposed as is customary, but is enclosed within the door frame 23, thereby improving the appearance of the front of the range, and permitting the counter-balancing means hereinafter described to be'located rearwardly. of the front.

Suitabie counter balance means is provided for the door 19. This means is so located that it will not be exposed or subjected to intense heat. To this end, it is mounted adjacent and outside of the double right end wall of the oven 12. Obviously the counter balance means is protected from the heat in the oven by the double walls 21 and 22, and also from the intense heat of the fire box by reason of its remoteness therefrom;

To improve the appearance of the stove and also to avoid hindrance in opening and closing the door, the counter balance means is located rearwardly of the door 19.

Preferably the counter-balance means comprises a rearwardly projecting lever arm 31 nonrotatably secured to the outer end of the trunnion 28. In this instance, the trunnion 28 is provided with a squared end which fits in a complementary hole in one end of the leverarm 31 and aheaded screw 32 is pro vided to retain the parts in assembled relation. A contractile spring 33 is secured at one of its ends to the free end of the lever arm, and is anchored at its other end to the base of the stove as by means of a laterally extending hook bolt 38. The spring 33 acts iiTa direction tending to move the door into closed position.

To protect the spring 33 and its associated parts from injury, they are enclosed in a housing 3% preferably extending the entire depth of the stove. The housing 3% in effect constitutes a right endextension of the oven under the reservoir, and is shaped to harmonize with the general contour and design of the range. The housing 3i is in the form of a plate secured along its; upper edge to the wall 22, then curving outwardly away from the wall, and then extending downwardly to the base 10. The ends of the plate are curved inwardly to the wall so that the plate and wall define a closed chamber 36 for confining the counter-balance means. 7

The lower end of the front of the casing recedes rearwardly to define a recess 37. A vertical front cover plate 35 in the plane of the front ofthe stove extends across the front end of the reservoir 16. The lower end of the plate is reduced in size and is curved rearwardly to project into the recess ly situated with respect to the firebox as not to be impaired by heat and it is, at the same time, shielded from view and guarded from accidental injury. 1

By positioning the oven door trunnions rearwardly of the front surface of the range the use of bulky external hinges is avoided and the appearance of the stove as a whole is greatly enhanced. V
