ASH-RECEIVING DEVICE.

Specification of Letters Patent.

Patented Nov. .5, ram.

Application filed May 14:, 1917. Serial No. 168,522.

To all whom it may concern:

Be it known that I, FRANK H. LEHMAN, a citizen of the United States, residing in the city of Lebanon, county of Lebanon, and State of Pennsylvania, have invented certain new and useful Improvements in Ash- Receiving Devices, of Which the following is a specification.

My invention relates to improvements in ash receiving devices for house heating furnaces and more particularly to that class of such devices wherein the ashes are adapted to be accumulated in a removable ash receptacle contained in a well or .cavity located in the furnace floor adjacent the ash pit.

In the form of devices of this kind here tofore in use, it has been necessary in order to permit of the vertical withdrawal of the ash receptacle from the well, either to first shift the same laterally from beneath the furnace or overhanging ash conveying means to a free and unobstructed position, or to employ receptacles with straight side walls requiring no appreciable protrusion of the conveying means thereover. Receptacles with straight sides are however objectionable since they lack the strength and durability of the reinforced cylindrical receptacles now in common use, and are liable to denting and buckling.

The main object of this invention is to provide such construction of a well, re-

movable floor cover and ash conveying means, that the same may be employed 1n con unction wlth an ash receptacle of the conventional cylindrical type, without the necessity of shifting the latter in the well to effect its removal. To this end a frame is provided for the well having as an integral part thereof an inclined spout or chute extending from the ash pit to the periphery of the well, and having mounted thereon a removable closure or cover plate carrying on its lower side, an extension of the chute for conducting the ashes to the central region of the well, thereby obviating any fixed hindrance or obstruction which might tend to prevent the free introduction and removal of the receptacle.

Another object of the invention is to provide a device of this kind which may be cheaply and economically manufactured and readily installed and which will not interfere With the ordinary regulation and operation of the furnace.

With the above and other objects in View, the invention consists in the novel construction, combination and arrangement of parts as hereinafter more fully described, claimed and illustrated in the accompanying draw ings, A represents a well or pit sunk in the floor in front of a furnace C and adjacent the ashpit D, and B represents a removable ash receptacle contained in the well. 2 represents a removable closure for covering the well which is mounted for hinged movement on a frame 1 and is adapted .when in closed position to be seated on an internal rabbet or ofiset l ofthe frame, the general construction of the closure and frame being patterned after that illustrated and described in my co-pending application for Letters Patent Serial Number 76,85 1, filed February 7, 1916, the hinge member preferably consisting of a pivot 3 which passes through lugs 6 on the lower side of the closure and is secured to the side walls of a hinge box 5 formed integral with the frame. The frame is seated in the neck of the well and is adapted, together with the closure when in closed osition, to rest flush with the surrounding oor.

On the side of the frame adjoining the ash pit is provided a chute 9, having a bottom 8 extending downwardly and inwardly from the surface of the floor to the periphcry of the well and having a suilicient inclination to enable the ashes dropped thereon to move by gravity into the well. For conveying the ashes to the central region of the well, I provide an extension chute 10. consisting of a box-like structure preferably bent up of sheet metal and having an inclined bottom 11, end Wall 12, sidewalls 13 and top and bottom openings 14 and 15 respectively, whichextension chute I attach by suitable fastening devices as clips and rivets 16 and 17 to the lower side of the closure 2. The closure 2 is preferably mounted for movement in a vertical plane at right angles to the chute 9, and the extension chute 10 is secured thereto in such manner that when the closure is in closed position the opening 14; thereof will coincide with the opening formed between the lower side of the closure, the inner edges of the bottom 8, and the side walls 19 of the chute 9. Said side walls 19 are flared outwardly from the bottom 8 as arelikewise the upper and contiguous portions 20 of the side walls of the extensionchute, and the inner edges of the bottom 8 and side walls 19 of the chute are rabbeted as at 21 to form a seat for said contiguous portions of the extension chute, thus allowing the bottom 11 of the latter to fall slightly below the bottom 8 and permitting the chutes to be closely nested together so as to prevent leakage of ashes into the body of the well. Thus when the closure is in closed position ashes dropped in the chute 9 will pass downward over the inclined bottom 8 thereof into and through the. extension chute 10 and be deposited centrally in the receptacle B. By this arrangement the receptacle B may be filled evenly to its full capacity without overflowing, or scattering ashes into the well.

By suitable construction of the hinge box and closure, the upward and outward limit of movement of the latter is so defined, that when it is swung open to its fullest extent, the extension chute carried thereby will fall out of line with the well and will not interfere with the free introduction and removal of the receptacle.

Preferably I locate the well immediately in front of the furnace as shown in Fig. 2 so that the ashes may be raked directly out of the ash pit into the chute 9, and for covering the floor opening of the chute I provide a removable closure as 22 which may be mounted as in this instance on trunnions as 11 seated in recesses 12 in the side walls of the chute and may have an overhanging lip as 23 adapted to rest on the upper edge of the chute. A finger piece as 24 permits this cover to be thrown back when it is desired to uncover the opening for depositing ashes in thechute. Inthe modified form of the invention shown in Fig. 4, the well is located somewhat closer to the furnace and the chute 9 is disposed beneath the ash pit, a plate 25 being substituted for the hinged closure 22, said plate having an opening 26 therein coinciding with a similar opening (not shown) in the bottom of the ash pit. In this form of the device, the ashes drop directly through from the furnace into the chute and the necessity of raking them out of the ash pit is thereby avoided.

lVhile I have shown and described the preferred embodiment of my invention, it is understood that the same is susceptible of modification in various particulars without departing from the spirit or scope thereof or sacrificing any of its advantages.

'What I claim is:

1. In an ash receiving device, a well, an ash receptacle adapted to be contained therein and vertically introduced and removed therefrom, a frame surrounding the mouth of the well, a closure mounted for hinged movement in said frame, said frame and closure resting flush with the floor, an inclined chute in said frame for conveying ashes by gravity into the well from a. point adjacent thereto, and removable means carried by said closure for receivingthe ashes from said first mentioned chute and conveyingthe same to the central region of the well.

2. In an ash receiving device, a well, an ash receptacle adapted to be contained in the well and to be vertically introduced and removed therefrom, a frame surrounding the mouth of the well, a closure for the well mounted for hinged movement in said frame, an inclined chute formed integral. with said frame for conveying ashes into the well from a point adjacent thereto, and an extension chute secured to the lower side of the closure for receiving the ashes from said first mentioned chute and conveying the same to the central region of the well.

3. In an ash receiving device, a well, a removable receptacle adapted to be introduced and removed from the well, an inclined chute fixedly disposed adjacent the mouth of the well for conveying ashes by gravity into the well from a point adjacent thereto, a closure for covering the well mounted for hinged movement in a suitable frame and carrying means for conveying the ashes from said chute to the central region of the well, said closure being arranged for movement on its hinge in a plane at right angles to the direction of said chute.

In testimony whereof, I have hereunto set my hand'in the presence of two subscribing witnesses.
