STOVE-GRATE.

nisosaa.

Application filed October 6, 1913.

To all whom it may concern Be it known that I, ANNA STEINLY, citizen of the United States, residing at Mongo, in the county of Lagrange and State of Indiana, have invented certain new and useful Improvements in Stove-Grates, of which the following is a specification.

The present invention relates to new and useful improvements in stoves and aims particularly to provide a novel and cfiicient form of grate which is hingedly mounted in the fire-box so that it may be swung downwardly to effect the complete displacement of all ashes, cinders and dead coals during the act of cleaning out of the stove.

An object of equal importance with the foregoing is to equip the grate with a guide chute which will operate to insure the passage of the ashes and cinders directly from the grate into a receiving pan, such as is ordinarily removably disposed on the bottom of the fire-box. l

A still further object is to construct the grate and associated mechanism with such regard to proportion, number and arrangement of parts that they may be cheaply manufactured, will be durable and efficient in their action and may be quickly and conveniently applied to any standard form of stove with a minimum expenditure of time and labor and without requiring the disassembling of any of the parts of the stove.

The above and additional objects are accomplished by such means asare illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

\Vith reference to thedrawings, wherein I have illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals desig nate corresponding parts: Figure 1 is aperspective view illustrating the grate and associated structure in assembled position in the fire-box of an ordinary cooking range, portions of the stove body being broken away to clearly disclose the interior arrangement of the parts; Fig. 2 is a vertical section taken through the fire-box; Fig. 3 is a detail view of the grate hinge-rod; and Fig. 4 is a perspective view illustrating' a modification of the preferred form of grate.

Specification of Letters Patent.

Serial No. 793,633.

Proceeding now to the description of the drawings, the preferred embodiment of this invention includes a hinged grate l0 and a discharge chute 11. f

The grate 10 may be of any suitable type, although in practice is has been found deenable to employ a grate of the bar type formed of cast iron, as illustrated in the accompanying drawings. This grate carries on one longitudinal edge a hinge-rod 12 to which it may be secured by welding or any other expedient, this invention comprehendlng, of course, the employment of collars and set-screws, or any other similar devices. The terminals of this hinge-rod 12 are journaled in alined apertures formed in the end walls of the fire-box, the one terminal being formed with an enlarged squared head 13 which is disposed exteriorly of the stove and is provided for thepurpose of permitting the application of a wrench, or other similar tool, when it is desired to swing the grate from dependent open position to horizontal closed position, as will be hereafter more fully disclosed.

As a means for supporting the grate in horizontal closed position and at the same time permitting it to be readily released to drop into dependent position, as indicated by dotted lines in Fig. 2, there has been pr0- vided a number of plunger pins 1-1 which extend in spaced relation to each other and project laterally from a head-board 15. These pins 14 operate through spaced bores or apertures formed in the wall of the firebox and are normally heldwith their major portions disposed interiorly of the fire-box through the medium of helical springs 16, which arewound around the pins and are interposed between the head-board and the adjacent outer face of the fire-box wall having their opposite terminals connected to the firebox and head-board.

From the foregoing it is of course obvious that when the operator desires to release the grate it is only necessary to pull the head-board away from the wall'of, the fire-box with the resultant withdrawal of the pins from supporting engagement with the grate. When the grate is released, it will of course, swing downwardly. permitting the ashes and cinders to fall to the ash pan, conventionally illustrated at 17.'

As a means for insuring the complete deposit of ashes in the ash-pan, there has been provided a discharge chute, heretofore designated by the numeral 11. This discharge chute consists essentially of a metallic casing 18, the side and end walls 19 and 20 of which are downwardly convergent and obviously tend to deposit the falling debris to the center of the ash-pan. Bolts, rivets, or other suitable fastening devices, indicated at 21, may be employed in holding the discharge chute in the desired position within the lire-box.

In order to limit the downward movement of the grate, there has been provided a suitable arm 22 which is preferably formed of a strip of strap metal, one terminal of which is indicated at and is folded or otherwise secured to the wall of the fire-box. The major portion of the member 22 is inclined downwardly from the rear wall of the fire-box toward the front wall and is equipped at its free terminal with an angular projection 24 which engages the grate 10 and holds it against further downward movement, as will be readily observed upon reference to dotted lines in Fig. 2. It will be noted upon reference to this figure that the angular portion 2-1: of the member 23 extends through a slot formed in the adjacent wall of the casing 18.

In the modification illustrated in Fig. 4, the grate is, as in the preferred embodiment, equipped with a hinge rod 12 having a square head 13, but differs in that its longitudinal edges are equipped with inwardly directed flanges 14: which extend in parallel spaced relation to the plane of the body of the grate, being adapted to receive a slidable plate 15 which is equipped with a handle 16.

l hen this modified form of grate is employed, a slot is formed in the end wall of the fire-box to permit the insertion or removal of the plate 15. Relative to the func tion of this plate 15, it will be apparent that, if the operator desires to shut off the draft from the combustion chamber for the pur pose of banking the fire, it is only necessary to insert the plate 15 between the flange. 14 and the body of the grate with the resultant sealing of the fire-box. It is obvious that, if desired, the plate may be inserted only part way, so that the heat will. be reduced or retained longer.

In conclusion, it is desirable to emphasize the fact that the grate and associated structure are constructed in such manner that all liability of breakage or derangement of parts is obviated and that by merely withdrawing the head-board in the manner above described, the operator may quickly remove all the ashes, cinders, and the like from the grate. it is further to be observed that the deposit of all debris from the grate into the ash-pan is insured by the provision of the discharge chute.

In the preferred embodiment of this invention there is provided an ash. receptacle which is illustrated in Figs. 1 and 2 and is designated by the numeral 25. This ash receptacle is substantially rectangular in shape and formed with a closed top and bottom, being preferably formed of sheet metal or some other similar material. In the closure of the casing is formed a rectangular opening 26 which is adapted to register with the lower end of the ash chute 18 when disposed in the bottom of the fire box in the usual receiving position. It will be noted that this form of ash receptacle insures a complete deposit of all the ashes in a restricted area and that the entire deposit of ashes may be withdrawn by merely removing the ash pan.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily var y.

I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my inven tion, as defined in the appended claims.

Relative to the various modifications to which the present invention may be subjected, it is desirable to direct attention to the fact that the discharge chute 11 may be bolted flatly against the inner wall of the fire-box along its upper edge instead of being spaced away from the fire-box walls a .ligl t distance as shown in the drawings.

Having thus described the invention what is claimed as new is 1-- 1. The combination with a fuel burner, of a grate hingedly mounted in the combustion chamber thereof, means for limiting the downward swinging movement of the grate, and a supporting member for normally holding the grate in horizontal position, said supporting member including a headboard, a plurality of pins carried thereby and adapted to project through the wall of the fire box for supporting the free edge of the grate, and a plurality of helical springs wound about the pins and secured at their terminals to the wall of the fire box and the head-board, said springs being adapted to normally hold the pins in supporting relation to the grate.

2. The combination with a fuel burner, of a grate adapted to be hingedly mounted in the combustion chamber thereof, a hingerod carried by the grate and journaled in the walls of the combustion chamber, a 7

squared head formed on one end of the hinge-rod and disposed exteriorly of the combustion chamber, for the application of an operating tool, and means for supporting the grate in horizontal position, said means including a plurality of plunger pins mounted for movement through apertures formed in the walls of the combustion chamber, springs for normally holding the inner ends of the plunger pins in supporting relation to the grate, and a head-board connected to the plunger pins and disposed exteriorly of the combustion chamber, whereby all the pins may be simultaneously withdrawn from supporting relation to the grate.

3. The combination with a fuel burner, of a grate hingedly mounted in the combustion chamber thereof, means for normally supporting the grate in horizontal position, a

Copies of this patent niay be obtained for five cents each, by addressing the Commissioner of Patents guide chute positioned in the combustion chamber below the grate, and a stop arm secured to the wall of the combustion chamber and projecting into the chute, said stop arm being formed of resilient strap metal and being adapted to limit the downward swinging movement of the grate.

In testimony whereof I aflix my signature in presence of two witnesses.
