GOAL CHUTE.

Application filed September 28, 1923. Serial 110,665,484.

T o all whom t may concer/n:

Be it lmown that I, JOHN E. MCMINN, a citizen of the United States, residing at- Louisville, in the county of `Jefferson and State of Kentucky, have invented a certain new and useful Improvement in Coal Chutes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My present invention relates to improvements in that class of devices known as coal chutes that are designed to be set into a foundation or other wall of a building and through which coal or other material may be passed into the building, as into the basement or coal room.

The general objectsof the invention are to provide a comparatively simple and inexpensive device of the aforesaid character that presents a neat appearance when built into a wall, is very substantial and durable, and is particularly convenient of operation when it is desired to open the chute for the reception of material, or close it after the material has been discharged through the chute.

Further objects are to provide a chute of the class referred to that is yequipped with a door having a pane of glass or other transparent or translucent material so that light ymay be admitted through the chutewhen the door is closed, and which door is adaptn .ed to be retracted into the chute in such a position that the pane is not liable 'to become broken through being struck by material passed through the chute; to provide latch mechanism for locking thedoor in closedposition from inside and which is arranged to be released from a distant point when it is desired to open the door; to so balance the door that upon the release of the latchy the door will swing aj ar so that a person lon the outside of the building may move the ,door to its full open position; to provide, in a device ofthe character referred to, a chute extension or hopper that is movably connected to the chute in such a way that it kmay be drawn out of the chute for use and held there by suitable means or released ,and moved into the chute when not in use; to provide a mounting for said chute-extension or .hopper involvinga part that is engaged by thedoor as the door lapproaches closed position. and through the intervention of ,which the "door when closed returns ythe chute extension or hopper toits fully retracted or normal positionwithinlthe chute.

The objects above set" forth, lwith others hereinafter appearing, are atta-inedin the construction illustrated in the accompanying drawings whereinlFig. lis afrontpelevation; Fig. 2 a rear elevation and Fig. 3 .an end elevation of my improved chute; Fig. 4 is a vertical section through the chute on the line 4-4- of Fig. 2, looking in the'direction of the arrows; and Fig. 5 is a view similar to Fig. 4 showing the door of ,the chute open vand the chute extension` or hopper extended in receiving position.

The chute proper is in the nature of a box like casing made up of integral top and end walls 1 and 2, respectively', and ai bottom wall 3 that is provided with flanges llat its ends which, 4as shown in Fig. 2, overlap the outer sides of the lower edges of the Aend walls 2 and are secured thereto by suitable means. Applied to the front of this structure is an open rectangular "frame 6 of neat design and shown as having a peripheral flange 7. A lip 8 projects 'from the inner or rear side of the frame adjacent the edge of its opening, and the front edges of the top wall 1, end walls 2, and bottom wall 3 are secured to enlargements or bosses 9 of the lip by bolts 10, or their equivalents.

Extending along the bottom side and each end of the frame are shoulders 12 which correspond to thestops iii-ordinary door structures, and for that reason I shall refer to said parts hereinafter as stops. The top ends of the end stops 12 are enlarged somewhat and extended inwardly, as best seen in Figs. 1 and 2, the enlargement of one of the stops being revealed in the former view where the door is broken away. Guides 13, which in the present instance are in the nature of angle bars, extend horizontally along the end walls 2 and may be secured to said walls by any suitable means; and the top surfaces of the guides 13 are substantially ,100

flush with the upper ends of the stops 12. Directly in front of the guides 13, the front frame 6 `is provided with hollow enlargements providing pockets 15 that open outside the frame through the sides of theen- 2105 largements, for a purpose whichshall presently appear.

The door is designated 18` and in tliepresent embodiment itv has an openingflS that is closed by a glasspane QGVheldY inplacejby :7,110

v hinge like connection between the door and frame, andthe door is adapted to be swung from a vertical to a horizontal position upon `thetr'unnions When in thel latter position,

itlm'ay be slid rearwardly along the guides 13 into theposition shown in Fig. 5 where it will be. out of the way and protected against breakage of the pane 2O when coal or" other material is passed through the chute.v j

Pivoted upon a boltor pintle 26, that is `.supported by and between lugs 27 which project rearwardly from the lower edge of the door,-is a latch plate 28 having a nose 29`that, is arranged to engage over a keeper 30 shown as formed integral with the frame A6. ,A flexible element or chain 32 has one of .its ends connected to the latch plate 28 l and is led therefrom, through a guide 33 ,atthe t'op of the door and an eye 34 that is ,i carried by the top wall 1 near its rear edge,

to a point within the building where it may be conveniently pulled for the purpose of releasing the latch. The guide 33 is shown as formed by a pin or bolt 35 that extends through spaced lugs 36 which project inwardly andupwardly from the top edge of the door. Y

, 7 To facilitate dumping or shoveling coal or other material through the chute, I proy videa chute extension or hopper 40 which is `swung at its forward edge from the frame 6 throughlinks 41. The lower ends of the 4rlinks are pivotally connected, through rivets i42er the like, to the Aend walls of the hopper and the. upper ends of the links are similarly connected, through bolts 43 or the like,

j. to lugs 44which extend inwardly from the l stops 12. Abutments 45 are applied to the .bottom ofthe hopper for engagement over n the bottom door stop to hold the hopper in lextendedposition, as illustrated in Fig. 5.

Vllithmy improved chute constructed and installed asdeS'Cribed, when it is desired to `Open the chute the flexible element` or chain ,32 is. pulled to release the latch plate 28 Y from the keeper 30 whereupon the door, by reason of, the manner in which it is balvanced, and the further fact that it is forced .outwardly somewhat by the weight of the .hopperAQ vtransmitted theretolthrough the links 41, swings. to the dotted line position shown in Fig. 4. The door may then be swung to a horizontal position and slid in along, the guides 13 to a position shown in y5 ,after` which the hopper may be withfpfflra'wn from thechute and held in extended position'by the abutments 45, as above explained. After the coal or other material has been passed through the chute, the abutments 45 may be released from the stop 12, as by striking the hopper from underneath with a shovel and the hopper, pushed back into the chute and the door 18 withdrawn from Ithe guides 13 to lodge the pintles 24 within the pockets 15 after which the door may be allowed to swing downwardly to closed position, and upon its being fully closed the nose 29 of the latch plate 28 will reengage the keeper 30 and retain the door in closed position.

Having thus described my invention, what I claim is: v
