STOVE OR RANGE DOOR OPENING AND CLOSING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 440,848, dated November 18, 1890.

Application -led .I une 16 1890.

T @ZZ whom, t muy concern.: Y

Beit known that I, CHARLES H. MILLER, a

' citizen of the United States, residing at Erie,

in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Stove or Range Door Opening and Closing Mechanisms; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention consists in the improvements in stove or range door opening and closing mechanisms hereinafter set forth and eX- plained, and illustrated in the accompanying drawings, in which- Figure l is a front elevation of arange embodying my invention. Fig. 2 is an end elevation of a section of the same, showing the operation of my improved door opening and closing mechanism. Figs. 3, 4, 5, and 6 are detail views of parts of my improved door opening and closing mechanism.

Like letters refer to like parts in all the iigures.

In the construction shown of my improved stove or range door opening and closing mechanism, A is a range, and B the oven-door and C the Warming-oven door thereof, both of which doors are hinged at their lower corners to the rangeA, so as to open outward and downward. One of the pintles co of the door B passes into a bearing D, and has secured thereon a segment d of spur-gear, which intermesheswith a segmentE of spur-gearmounted in bearings e below the bearing D. Mounted on the pintle a, so as to partially cover the spur-gear d, is a lever F, adapted to engage with a catch f on the spur-gear CZ when being depressed and rotate the spur-gearcZ, secured to the pintle a, which operation also actuates the spur-gear E, intermeshing therewith. The spur-gearE is provided with an arm G, which is adapted to receive one end h of a footrail H, which is adjustably secured thereto, as and for the purposes hereinafter set forth. The other pintle hof the doorB passes through a bearing` I, and is provided with a crank J, which extends through an opening into-the Serial No. 355,667. (No model.)

ash-vault K of the range, where it is coupled by means of a link k to a heavy cast-iron ashchute L. This ash-chute L is hinged at its rear end to the range by means of pintles Z, while the outer or front end rests entirely upon the link 7c and crank J, scoured to the pin tle b, so that the opening of the door B, asshown by the dotted lines in Fig. 2, serves to raise the outer end of the weighted ashchute L, which operates to counterbalance the weight ofthe door B.

Below the bearing I, and in line with the bearing e at the opposite side of the door B, is a bearing M, in which is mounted a short arm N, adapted to receive the opposite end h of the foot-rail H, adjustably secured thereto, so that the foot-rail H swings freely up and down, as particularly illustrated by dotted lines in Fig. 2, the gearing d E serving to operate the foot-rail H in unison with the movement of the door B, the foot-rail l-I operating as a partial counter-balance for the door B. The foot-rail H also operates as a brace for the door B, engaging with lugs or stops g g thereon when the door B is completely opened, as shown in the dotted lines in Fig. 2. The foot-rail H also operates to close the door B, this being accomplished by pressing downward on the foot rail I-I, which operates through the gears E d to raise the door B upward and close it. In opening the door B it is only necessary to depress the lever F, which operates to throw the door B open.

The latch O on the door B is an ordinary gravity-latch adapted to engage with a catch P, which I preferably make adjustable, so that the catch P can be adjusted so that the latch O can be disengaged therefrom by pressure upon the lever F, so that in opening and closing the door B the same will operate automatically.

When the door B is closed,the foot-rail I-I rests against the lower part of the range A, and when the warming-oven door C is opened it operates as a support therefor, as is illustrated in dotted lines in Fig. 2.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent of the United States, is-

1. rlhe combination, in a stove or range door opening and closing mechanism, of a door opening downward and outward, with a IOO weighted ash-Chute hinged atits inner end to the stove or range and Coupled at its outer end by means of a link to a crank on one of the pintles of said door, substantially as and for the purpose Seifer-th.;l l

2. The combination, in a stove or range door opening and closing mechanism, of a Counterbalaneed door opening downward and outward, a spur-gear on one of the pintles of said door, and a door-opening lever adapted to engage said spuihgear when operated to open said door, with an adjustable foot-rail mounted in bearings adjacent to the bearings ofthe door-pintles, and a spur-gear on one of the bearings of said foot-rail intermeshing with the spur-gear on the door-pintle, substantially as and for the purpose set forth.

3. The combination, in a stove or range door opening and closing mechanism, of a door openin g downward and outward, and a hinged counter-balance coupled to a crank on one of the pintles of said door, with a spur-gear on one of the pintles of said door, adoor-opening lever engaging said spur-gear, a foot-rail hinged in bearings under the door-pintle bearings, and a spur-gear on one of the foot-rail bearings intel-meshing with the spur-gear on the door-pintle, whereby the door and foot-rail move in unison, substantially as and for the purpose set forth.

4E. The combination, in a stove or range, of a door B, opening downward and outward7 with a foot-rail H, geared to said door B by means of a spur-gearE thereon, intermeshing with a spur-gear CZ on the pintle of the door B, so that the opening of the door moves the foot-rail H upward in unison therewith as the door is being opened, until when the door is fully opened it engages with lugs g thereon and operates as a supporting-brace for said door, substantially as and for the purpose set forth.

In testimony whereof Iafx my signature in presence of two witnesses.
