STOVE-DOOR SPRING.

v11pplieation vfiled. July 2,

The present invention relates to the doors of cook stoves and ranges, and aims to provide a novel and improved spring means for counteracting gravity in the downwardly swinging opening'movementof the door, and for yieldingly holding thedoor closed.

It is the object of the invention to provide spring means of the kind indicated so constructed and arranged as to effectively`accompli'sh the results wanted, and to avoid objections that have arisen with the use of springs employed heretofore, such as the breaking of such springs and the jerky action thereof.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as

hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accom panying drawing, wherein- 1 Figure 1 is a rear view of a stove door and its frame, forming part of a stove front, and showing the improvements embodied therein.

Fig. 2 is a section on the line 2'-2 of Fig` 1, showing the door open in dotted lines.

Fig. 3 is a section on the line 3-3 of F ig. 2.

The door frame '7 forming part of the stove front is a metal casting, and the door 8 is hingedly mounted `thereon at the lower edge of the opening to swing open Voutwardly and downwardly. The door may be of any suitable construction, and in carrying out the invention is providedl with inwardly or rearwardly extending flanges or lugs 9 near the opposite side edges and lower corner portions of the door.

The angularly extending terminals 10 of rods 11 are engaged through apertures in the Iianges 9 to pivotally connect said rods with the door, and said rods extend rearwardly through slots 12 in the door frame 7. Said slots extend vertically to permit the rods to swing upwardly and downwardly.

Nuts 13 are screw-threaded on the rods 11 and when the door 8 is swung open, said nuts seat behind the frame 7 to limit the downward movement of the door, and to 1928. Serial No. 289,873.

arm 14 has a coil or eye y17 loosely Vsurrounding the corresponding rod 1 1 behind the nuts 13 forthe contact of a nut 18 threaded on said rod. Therefore, when the door is swung open,-the rods 11 being pulled outwardly, and the nuts 18 seating against the eyes 17, will spring the arms 14 forwardly, so that the springs counterbalance the door.

The arms 14 of the springs also press inwardly against the nuts 1,8, when the door is closed, in order to hold the door in closed position without the use of the usual spring catch that is objectionable because when opening a stove door there is a jerking action or shock when loosening the door from the spring catch.

The nuts 18 may be adjusted to regulate the influence of the springs, and the nuts 13 may be adjusted to support the door in the desired position when the door is swung open.

The arm 14 of each spring has a bent back terminal 19 forming a loop surrounding the corresponding slot 12 and rod 11, to prevent side slipping of the arm 15, and to provide a better seating surface between the spring and door frame.

Each spring is composed of one piece of wire, and the arms thereof are comparatively long, so that the entire spring is free to flex, without concentrating the strains on either arm or the coil of the spring such as would be apt to result in breakage of the spring. The spring has a free flexing action without restriction.

Members 20 are secured to the inner surface of the door frame 7 by means of bolts or screws 21 and have hooks 22 engaging loosely around the spring coils 16, to assist in holding the springs in place, but they do nothinder the flexing action of the springs.

With the present spring devices, the springs do not have rubbing or sliding contact with the door, the rods l1 being hinged ly connected with the door and serving to connect the door with the springs which are concealed behind the door frame.

Having thus described the invention, what is claimed as new is l. The combination with a hinged stove door and its frame, of a rod pivotally oonnected with said door, a wire spring having two arms and a coil between them, one arm bearing against the frame and having a loop surrounding said rod, the other arm having an eye loosely surrounding said rod, and an adjustable element on the rod bearing against said eye.

2. The combination with a hinged stove door and its frame7 of a wire spring having two arms and a coil between them, one arm bearing for a distance of its length against the frame, and the other arm extending away from the frame, and a rod pivotally connected with said door and having a portion engaging the secondnamed spring arm.

3. The combination with a hinged stove door and its frame7 of a wire spring having two arms and a coll between them, one arm bearing for a distance of its length against the frame, and the other arm extending away from the frame, and a rod pivotally conneeted with said door and having a portion engaging the secondnamed spring arm, the firstnamed spring arm having a loop surrounding said rod.

4. The combination with a hinged stove door and its frame, of a rod pivotally connected with said door, a wire spring having two arms and a coil between them, one arm bearing for a distance of its length against the frame and having a loop surrounding said rod, the other arm engaging said rod,
