ASH-CHUTE FOR STOVES.

Specification of Letters Patent.-

lPatented Nov. 26, 1912.

To all whom it may concem:

Be it known that I, RoLLIN H. BABBITT, J12, of Taunton, in the county of Bristol and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Ash-Chutes for Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention relates to and comprises a chute that will take theplace of the ordinary ash pan now commonly used in stoves, the chute forming a closed connection with the stove below the grate and communicating with an ash receptacle-located in the cellar in'such manner that ashes shaken from the grate will not only be directed into the receptacle in the cellar, but prevented from escaping from the chute; in other words, forming a dust-tight communication between the stove and the receptacle.

My invention can best be seen and understood by reference to the drawings in which Figure 1 represents in vertical section a portion of a stove and an ash chute embodying my invention connecting therewith and with an ash receiver or receptacle, the same being taken on the line 11 of Fig. 2. Fig.

2 is a view partly in vertical section and I partly in elevation of the stove, connecting ash chute and ash receiver, the same as shown in Fig. 1, excepting that the view is taken at right angles to the parts shown in Fig. 1. Fig. 3 is a side elevation of the hopper hereinafter described as a part ofthe chute. Fig. 4 is a plan of the bottom of the hopper and sliding damper connecting therewith. Fig. 5 is a view partly in side elevation and partly in section of the bottom end of the chute showing a portion of one of the pipe sections forming a part of the chute and the cover of the ash receiver or receptacle loosely arranged upon the pipe section in an upright position as will hereinafter be explained. Fig. 6 is a view partly in section and partly in plan of the same pipe section and cover, the cover being shown, however, in its closed or upright position with respect to the pipe section and top end of the ash receiver or receptacle. Fi 7 shows an enlarged sectional detail 0 construction to which reference will hereinafter be made.

1 represents the body of the stove and 2 the grate chamber and 3 the grate.

4 is the usual chamber below the grate and in which an ash pan is customarily placed.

side and end walls 6 and 7 respectively.

These walls unite or connect with the body of the stove to have closed communication with the grate chamber below the grate in the following manner :As is customary in stoves the grate chamber is provided with rectangularly-arranged walls 8. Cooperating with and extending downwardly and inwardly from these walls 8 at a point below the grate and between the grate and ash chambers is a rectangular flange-forming frame 9 having a downwardly-turned rim or edge 10. Attached to this frame 9 is a similar rectangular frame 11 which forms the top of the hopper and to which the respective side and end walls are secured (prefer ably by riveting). The frame 11 fits beneath the frame 9, being bolted thereto, and is provided along its inner edge or rim with a cup 12 into which the down-turned rim of the frame 9 is adapted to extend to form a joint. This joint is filled with cement or other suitable material, thereby providing an absolute closure between the hopper and the adj acent side walls of the stove and preventing the leakage'of air into the grate chamber from points around the hopper. ment ofthe parts is such, also, that the ashes from the grate will either fall directly into the hopper or be directed thereto by the downwardly and inwardly inclined rectangular frame 9 to which the hopper is secured, any ashes falling upon this frame along the sides or ends of the grate being directed into the hopper. The converging side and end walls of the hopper 5 are secured at their lower ends to a bottom piece or member 13 which forms the bottom of the .hopper and has an opening in it. This bottom piece or member is located preferably just above the bottom plate 14 of the ash chamber. For controlling the opening in it, the member or bottom of the hopper is provided with a horizontal sliding damper 15. This damper is accessible from the front side of the stove through the usual door 16 which opens 1nto the ash chamber. Connecting with the bot-.

The arrangetom 13 of the hopper in line with the opening in it is a pipe section 17. This connects with the hopper by slipping over an annular flange 18 dependent from the bottom of the hopper around the opening in it. The pipe section 17 extends through the bottom 14 of the ash chamber and through the floor on which the stove stands into the cellar beneath.

For convenience the pipe section 17 is made relatively short and is extended such distance as may be necessary by added sections. For purposes of illustration one added section 19 is shown. tions are secured to one another and held in .place in the following manner: The adjacent ends of the pipe sections are connected by means of an internal double-flanged col-- lar or thimble 20 over which the adjacent ends of the pipe sections are adapted to fit and be secured in any suitable manner, preferably by small bolts and nuts. The 'thimble is provided with an external annular flange 21. against which the respective ends of the pipe sections are adapted to bear, the flange extending beyond the annular plane of the pipe. Connecting with this flange are a series of stays 22 which extend up and are secured to the under side of the floor or ceiling through which the pipe section 17 extends, and act to hold this and the added sections forming the pipe securely in place. The added pipe sections or pipe are of such length as to connect with any suitable ash receptacle 23. Owing to the fact that the ashes are precipitated into this receptacle it is necessary that the pipe make a very close connection therewith to prevent escape of the ashes. While this connection might easily be obtained it is also essential that the connection be such as to admit of the receptacle being removed and its contents dumped as occasion may require. Provision is accordingly made by furnishing the receptacle 23 with a cover 24 through which the pipe loosely extends through an opening in the cover. The cover 24 is concave and provided with a dependent rim or flange 25 fitting snugly over the end of the receptacle. To add efliciency of closure the interior of the cover where it fits onto the end of the receptacle is provided With an annular Washer 26 made of asbestos or other suitable material and forming a cushion joint between the cover and the end of the receptacle.

As explained above the pipe extends loosely through an opening in the cover for it is necessary when the chver is removed from the receptacle to lift the cover on the pipe and provision is made after the cover is so lifted to hang the same on a hook 27 secured to the side of the pipe.

In order that the cover may be lifted freely on or over the pipe and not bind it The pipe secis necessary that the opening in the cover through which the pipe extends be a relatively large opening and through such an opening ashes would escape when precipitated through the pipe into the ash receiver. The cover is accordingly fitted with two circular hinged pipe guards 28 adapted to occupy an open position when the cover may be moved freely on the pipe, or a closed position, when they are adapted to fit snugly around or envelop the pipe and close the opening left between the pipe and the adjacent portion of the cover which forms the edge of the opening in it. These guards may be seen by reference to Figs. 5 and 6. As will be observed each guard -is made semi-circular in form and is provided with a rear bearing extension 29 which fits withina socket 30 made in the cover. The guard is held in place to turn within this socket by means of a spring 31 fixed at one end to the cover and extending over the socketed portion of the guard holding it securely in place and the guard in a normal turned-down position. When the guard is lifted the spring yields, the end thereof slipping into an opening 32, which extends through the guard just alongside its bearing and in line with the end of the spring, as the guard is opened or turned to an upright position. The arrangement is such also that each guard may be turned to an upright or open position away from the pipe, when the cover may be moved freely on it, or so far as to engage the rear side 33 of the socket formed in the cover which acts as a stop to prevent the guard from being turned back too far or where it might become released from the spring. For turning the respective pipe guards each is provided with one or more finger clips 34.

The operation of the device is as follows :Normally the damper controlling the hopper is closed preventing the entry of air to the grate chamber. When, however, the grate is shaken the damper is opened and the ashes will be directed to fall into the hopper and through the connecting pipe sections into the receptacle below, it being assumed of course that the cover is in place and the pipe guards on the cover turned down to envelop the pipe. The damper controlling the hopper may then be closed. When it is desired to remove the ash receptacle the pipe guards on the cover are turned up when the cover may freely be lifted on the pipe and hung upon the hook as illustrated in Fig. 5. The receptacle may then be removed from the pipe.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In combination, a stove having a grate chamber, a grate therein, and an ash chamber beneath said grate chamber, .a hopper located in said ash chamber and having con verging side and end walls a downwardly-t inclined rectangular flange-forming frame connecting with the walls forming said respective chambers and provided with a down-turned rim or edge, a rectangular frame forming the top of said hopper and attached to said rectangular flange-forming.
