I COAL CHUTE.

Application filed July 18, 1922. Serial No. 575,876.

To all whom it may concern:

Be it known that I, JOHN E. MoMiNN, a citizen of the .United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful" Improvements in Coal Chutes and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in chutes for coal .or other fuel, or the like, in which it is intended to provide a convenient and unobtrusive, if not ornamental, ar-

rangement which will remain closed when not in use; and at the same time will alford more or less light to the coal cellar or fuel bin when in the closed position, but which may be readily opened for use and conveniently restored to the initial closed position when desired. r

My invent-ion will be more fully understood after reference to the accompanying drawings, in which like parts are indicated the several views, and in which Figure 1 is a front view of the device as seen from the exterior of the building in which it is used. I

Figure 2 shows a side elevation of the device. as detached.

Figure 3 is a rear view, on a larger scale, showing the interior of the device, parts being broken away; and

Figure 4 shows a section along the line 44 of Fig. l, and looking in the direction of the arrows, but on alarger scale than in said figure. j

' A represents the frame adapted to be mounted in an opening in the wall of a building, as above the pavement or in any other convenient location. This frame may be mounted in the masonry ofthe building,"

or secured to the wooden framework of the building in. any convenient way. The method of mounting, not being a part of my invention, is not shown herein. I

Attached to the rear of this frame A is a hood B, preferably made of sheet metal, and having an inclined lower bottom portion B to direct the fuel downwards and inwards. This hood may be attached toflthe frame in any convenient way, as by the bolts C.

by similar reference symbols throughout D representsa door frame, in which a panel 1?, preferablymade of, heavy glass with wire embedded therein, is secured in any convenient way as by means of the, clamps E. The'edges ofthis door frame,

engage thefianged portions (1 anda of the mainframe A, as shown in Fig. 4, whenthe door IS in the closed position indicated in full lines in said-figure. The door frame D isprovided at each side with lugsd to which the flange. f of the arm F. is secured, as by means ofthe bolts d. [There are two of".

these arms F, one on, each side of'the hood B, and each of these arms carries a counterweight F soadjusted as to automatically lift the door or swing it to the open positlon, as shown in dotted lines in Fig.1 4,

after described. 7 I

These arms F are pivoted,'as at G, to the hood B. i

The door is normally held in the closed positlonby means of the sliding catch I, having its nose i projecting up into the when "the latch is released as will be herein;

notch a formed in the lug A in the upper portion of the main frame A, adjacent to which notch the lug is provided with ;'a wedge face 0, asshown in Figs.'3 and 4. This catch is normally held in the closed position by means of the took of the lever.

H which is pivoted, as at h", to the lug D v forming part of the door frame, as shown most clearly in Figs. 3" and 4.

"To the longer arm of this lever on this chain, as from a floor above, the catch I is pulled down and thedoor frame in Fig. 4, where the glass pane willbe'entirely masked in theupper portion of the n the" cord or chain J is attached. By pulling up.

hoodand will not be injured by the dumping of coal'or other solid material into the chute.

In order to provide an automatlc extension of the coal chute which will project out beyond the faceof the dooropening, when the door is lifted, and-which will be swung back in the position behind the door, when the door is closed, I providean auxiliary chute N, which is'provided at its upper and" outer pro ecting end with areinforcing strap a, pivotally'connected, as at m, to the link M, which link is pivoted, as at m to the counterweight F. There are two of these links M, one on each side of the hood, as shown most clearly in Figs. 8 and 4. The auxiliary chute is pivoted at points nearly opposite the pivot m, as by means of the bolts 0, to the lugs A projecting inward from the main frame A, as shown in Figs. 3 and 4:. When the door is closed this auxiliary chute will be swung up into the position shown in full lines in Fig. 4, and when the door is opened the chute will be swung down to the position shown in dotted lines in Fig. land in such position will project beyond the edge of the door opening and will serve as an inclined chute to direct the fuel or other solid material into the hood B, which fuel will slide, by its own weight, down the inclined bottom 13 of the hood B. The operationof the device is as follows:

The appartus being mounted in the side of'a house in any convenient way, and the door being closed, and the parts being otherwise in the position shown in Fig. 4:, if it is desired to open the door lift on the chain J. This will cause the toe it to draw down'the catch 1, disengaging the nose 2' of said catch' from the notch a", and the counterweight F will then swing the door frame and door upwards, causing these .to assume the position shown in dotted lines in F ig. Q. If the auxiliary chute is attached, this auxiliary chute will be at the same time rocked about its pivot 0 until it and its supporting links assume the position shown in dotted lines in Fig. 4, at

which time the bottom m of the auxiliary chute will project outwards beyond the door opening and will facilitate the supply of fuel to the chute.

In order to restore the parts to the initial position, pressing down on the links M near their pivots m, will swing the coun-- terweights F backwards, and simultaneously lifting up on the outer edge. of the bottom of the auxiliary chute will facilitate the restoring of the parts to the position shown in full lines in Fig. a l. When the nose i of the catch I engages the wedge face cfiof the lug A" this catch will be pressed backwards until the nose 2' registers with the notch aflwhen the weight of the lever H and the chain J will restore the catch to the initial position, and the parts will be' made of a neat exterior and is not objectionably conspicuous in any way, or it may be made quite ornamental if desired.

Furthermore, it will be noted that the glass used for illuminating purposes is set back so as not likely to be injured by ordinary accidents and is removed entirely out of the way when the solid material is being delivered to the chute. It will be obvious that in place of glass a panel made of metal or wood may be used if desired, but glass is preferable because it transmits light,

It will be obvious that various other modifications might be made in the herein described construction, and in the combination and arrangement of parts whichcould be used without departing from the spirit of my invention; and I do not mean to limit the invention to such details ex cept as particularly pointed out in the claims.

Having thus described my invention what i I claim and desire'to secure by Letters Patent of the United States is Y v r 1.
