STOVE-DOOR.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed June 15, 1989. Serial No. 502,388.

T 0 all whom it may concern:

Be it known that I, BERRY A. BAXTER, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Stove- Doors, of which the following is a specification.

My invention relates to improvements in stove doors.

One of the objects of my'improvement is to provide means of retaining a stove door in a closed position by the weight of the parts of the operating mechanism and also to hold the door in place when it reaches its full open position.

Another object is to provide a cheap and eflicient means of retaining the door in its closed and full open positions.

1 attain these and other objects by the mechanism illustrated in the accompanying drawing in which:

Figure 1 is a vertical section of my device showing it applied to a stove door with the door and retaining mechanism in full open position. Fig. 2 is a vertical section of Fig. 1 showing the door with the retain ing or locking mechanism in closed position. F 3 is a plan view of the counterweight showing depressions in the surface to permit of the ends of the links to be pivoted below the surface. Fig. 41 is a plan view of the opposite side of the counten weight shown in Fig. 3 showing depressions into which one end of a connecting bar is attached. Fig. 5 is a side or edge view of Figs. 3 and 4t. Fig. 6 is a plan view of a yoke shaped connecting bar. Fig. 7 is a plan view of one of the links. Fig. 8 is an edge or side view of one of the links showing the off-set bends. Fig. 9 is a horizontal sectional View of the device showing the counter-weight in contact with the ovenwall to maintain the door in open position.

In the drawing, reference numeral 1 represents the oven of a stove and 2 one of the side walls. Links 3 are pivotally secured to the side walls of the oven by the pins 4- and they are provided with offset bends 5 and 6. Connecting bars 7 preferably made in the form of a yoke as shown in Fig. 6 are pivotally connected to the door and the free ends a and Z) are secured to a weight 8 by the screws 9 and 10 and it is further prevented from longitudinal movement by the notches 11 formed in the ends of the c011- necting bar which engage the rib 12 which crosses the grooved portions 13 of the counter-weight.

Depressions 1 1 and 15 are provided in the counter-weight 8 and one end of the links is pivotally attached to the counter-weight as shown in Figs. 1 and 2 by the pins 16 and 17. The depressions 1 and 15 are provided in the counter-weights for the purpose of permitting the ends of the links 3 to pivot freely below the surface of said counter-weights to operate in close proximity to the side walls of the oven. Although two depressions, designated 1% and 15, are provided, as shown in Fig. 2, it is obvious that only the lower one is used when the door mechanism is assembled and the links connected to the counter-weights. The purpose of providing two depressions is to permit the use of the same counterweights on either the right or left side of the oven wall. This arrangement pivotally connects the door 18 to the counter-weight S which is in turn pivotally connected to the side walls of the oven as described. The door is hinged to the walls of the oven in the usual manner.

The operation of my device is as follows: I hen the door is being closed, the counterweight with its operating mechanism is forced to travel toward the back or rear wall of the oven, transcribing an are on the radius of the links 3 until it assumes the position shown in Fig. 2. lVhen the links 3 and connecting bar or bars 7 are parallel with each other, the door is in close proximity to its closed position and the weight of the parts becomes effective to keep the door closed. hen, however, the links and con necting bar or bars of the door are at an inclination to the plane of the oven, as shown in Fig. 2, the counter-weight with its operating mechanism securely holds the door in close contact with the walls of the oven as they pass over the center of the axis of the pivotal connection and have a tendency to movably lock the door in closed position. The counter-weight and the operating mechanism serve to offset the weight of the door and retain it in its closed position. lVhen the door is being opened, the links and weight are forced to travel in a forward direction toward the front of the oven, transcribing an are on the radius of the links in the opposite direction from that of closing until they assume the position shown in Fig. 1, which shows the door in full open position forming a shelf level with the bot tom of the oven. The counter-weights are drawn forward by the connecting bar or bars and they strike the front walls a a of the stove thereby retaining the door in the position shown in Figs. 1 and 9.

The above arrangement describes a cheap and effective means of retaining a stove door in closed and open po tions.

Having fully described my invention, what I claim and desire to secure by Letters Patent is:

1. In a stove, a hinged door, links pivotally connected to the walls of the stove at one end, counter-weights pivotally secured to said links, connecting bars pivotally connected to the door and rigidly connected to the counter-weights.

2. In a stove, a hinged door, links pivotally connected to the walls of the stove at one end, counterweights pivot-ally secured to said links, a yoke-shaped connecting bar pivotally connected to the door and rigidly connected to said counter-weights.

3. In a stove, a hinged door, a link pivotally secured to said stove, a counter-weight pivotally secured to said link, a connecting bar pivotally secured to said door and rigidly connected to said weight whereby the door is maintained in a closed or open position.

at. In a stove, the combination of an oven and a hinged door; of counter-weights; connecting bars pivotally secured to said door and rigidly secured to said countereights, links pivotally secured to the side walls of the oven and to said counter-weights Where'- by the counter-weights and operating mech- I anism serve to keep the door in close contact with the Walls of the oven as described.

5. In a stove provided with a hinged door, a bar pivotally connected o said door, a weight secured to the free endof said bar,

a link pivotally connected to the walls of pivotally secured to said stove, a weight' pivotally connected to the free end of the link and rigidly secured to said bar, said link, bar and Weight cooperating to main tain the door in closed posltion under tension and to maintain thedoor in full open j position by contact of the weight with the walls of the stove as described and set forth. In testimony whereof I aflix my signature in presence of two witnesses.
