COMBINED ASH-CHUTE AND UNDERFIRE.
SPECIFICATION forming part of Letters Patent No. 551,174, dated December 10, 1895.
Application led January l 9,1 8 95.
T0 all whom t may concern:
Be it known that I, ARTHUR STRETTON, a subject of the Queen of Great Britain, residing at Vaverly, county of Middlesex, State of Massachusetts, have invented an Improvement in a Combined Ash-Chute and Underiire, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object the production of a combined underfire and ashchute for open fireplaces, whereby a solid foundation for the iireplace is attained without the use of tiling, dac., and providingl means for disposing of the ashes without the liability of their being blown into the room by the back-draft.
By my invention I overcome the derangement of parts and dangerous loosening of joints due to unequal settling of the fireplace, and this I accomplish by making the underiire of a single piece of iron or other iireproof refractory material, the ash-chute preferably forming an integral partthereof, the underfire resting on the masonry of the ash-duct and chimney, and the sides and back of the fireplace are built upon the upper surface of the underfire.
In accordance therewith my invention consists in an underiire having an opening therein, a cover-plate hinged at one edge of the opening and extended underneath the underiire, and an ash-chute below the underire and its opening and having an outlet in the path of and to be closed by the extension of the cover when the latter is lifted, substantially as will be described.V
Other features of my invention will be hereinafter described, and particularly pointed out in the claims.
Figure l is a top or plan view of a iireplace with my invention applied thereto, the back and side walls 0f the ireplace and the chimney-back being shown in section. Fig. 2 is a partial vertical section taken on the line x, Fig. l, looking to the right. Fig. 3 is a transverse sectional view of the underlire and ash-chute with the cover of the chute partially open, and Fig. 4 is an under side view Serial 110.535,574. (No model.)
I have herein shown the underiire as a plate a of metal or other refractory iireproof material, of a suitable shape and size to support the back and side walls b and h of the iireplace, the underfire a resting upon the masonry of the ash-duct A and chimney. (Shown in section in Fig. 4.) v
An opening cd is made in the underre, toward its front edge and midway between its sides, with its sides preferably slightly beveled inwardly, and under said opening an ash-chute d? is located, preferably made integral with the plate a, the inclined bottom a3 of the chute sloping rearwardly and downwardly from the front edge of said opening, as clearly shown in Figs. 2 and 3. A cover-plate c is pivoted at c' in the underflre, to normally close the opening a, the edges of the cover fitting snugly therein. The under side of the plate a is recessed at dx, (see Fig. 3,) at the back of the opening a', to receive therein the extension c2 of the cover c when the latter is in its normal closed position, Figs. l, 2, and 4. The extension c2 is of sufficient area to close the delivery end of the ash-chute when the cover c is raised, as shown in dotted lines, Fig. 2, the inclined bottom a2 of the chute extending to a point substantially beneath the pivots c of the cover, to thereby form a closed receptacle into which the ashes may be swept through the opening a', the chute when thus closed holding about an ordinary burning of coal or wood ash.
As the receptacle is closed there is no backdraft to blow the ashes about or to scatter them about the room,as they are swept through the opening a, and as the closing of the cover c opens the chute by withdrawing the eXtension c2 therefrom the ashes are free to slide dovm over the bottom a2 into the ash-duct A to a proper point of discharge, without making a cloud of dust as would be caused by dumping the ashesdirectly out of the chute. The cover c is slightly heavier than the eX- tension c2 and thereby is normally kept closed, and for convenience in raising it it is provided with a lip cx, a shallow recess or pocket d4 in the upper surface of the underfire a permitting the insertion of a suitable device beneath the lip CX.
Inasmuoh as the underfire a rests on the IOO masonry of the ash-duet A and the adjacent wall of the chimney, parts of the latter niay settle without causing a separation of the joints of the fireplace or trimmer-arch, for the fireplace is built upon and sustained by the underfire, which forms a iirln and solid foundation therefor. This obviates the settling of one part of the fireplace more than another, as is the case frequently when one part is built on the chimney-breast and another part on the trimmer-arch.
No tiling, hearth-brick, dac., is necessary, and the ash-chute, being an integral part of the underfire, cannot become loosened therefrom by settling or burning out of joints.
It will be obvious that as the cover cis pivotally supported at its rear edge, and lifts to uncover the opening a', it cannot be accidentally opened by the weight of anything placed thereon,such as an andiron, a grate, tbc.
I claiml. An underfire having an opening therein, a cover plate hinged at one edge of' the opening and extended underneath the underfire, and an ash-chute below the underiire and its opening and having an outlet in the path of and to be closed by the extension of the cover when the latter is lifted, substantially as described.
2. An underiire having an opening therein, a cover hinged at one edge of the opening and extended underneath the underfire away from the opening, and an ash-chute below the opening, the bottom of said chute inclining rearwardly from the front edge of the opening to beneath the pivotal point of the cover, to form a vertical outlet thercat in the path of' the cover extension, to be closed thereby when the cover is lifted, substantially as described.
3. An underiire for fireplaces, consisting of a rigid plate'of iireproof material forming the bottom of the fire place and having an ash discharge opening therein, and a hinged nor-' inally closed cover therefor, said underfire be ing laterally and rearwardly extended to sustain the back and side walls of the fireplace, substantially as described.
et. An underre for fireplaces, consisting of a rigid metal plate having an ash discharge opening therein, and an ash-chute composed of depending side walls and an inclined bottom on the under side of and integral with said plate, the bottoni of the chute inclining downwardly from the front edge of the discharge opening, substantially as described.
5. An underfire for fireplaces, consistingof' a rigid metal plate forming the bottom of the fireplace and having an ash discharge opening therein, an ash-chute on the under sido of and integral with said plate, the bottom ot' the chute inclining downwardly from the front edge of the discharge opening, and a cover for the opening pivoted at the rear side thereof and provided with an extension below the plate, to close the open end of the ash-chute when the cover is raised, substantially as described.
In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
