COAL-CHUTE.

To all "whom it may comem:

Be it known vthat I, MAGGIE B. LAING, a citizen of the United States, residing in the borough of Bronx, city of New York, in the county of New 'York and State of New York, have invented certain new and useful Improvements in Coal-Chutes, of which the following is a specication.

The object of this invention is to provide a device for conveying coal or similar material, from a vehicle' to an opening in the pavement or other place, which device will form a closed conveyer for the material to ei'ectually exclude the escape of dust or fine particles therefrom; and which device will also havethe property of deadening or preventing the noise and racket usually attendant upon the passage of coal down a chute or the like.

AA further object of the 'invention is to" partly in elevation, with the lower end in serted in" the coal hole. Fi 2 is a view showing the device in use. F1 3 shows the vehicle attaching member; an Fi 4 shows the attaching member for the coa hole.

Heretofore it hasbeen customary to use a chute formed of rigid material, generally sheet metal, that is attached at the openin in the tail-board of the vehicle, with its en placed at the opening in the pavement. With the use ,of such a'structure, whether of wood or iron, the running of the coal down into the hole from. the wagon always produced a large and objectionable noise especially where the device was made of sheetmetal. A further objection was ,the necessary spreading of dust and tine parti-v cles'in the neighborhood. The results of such objections has been in large cities, that itis prohibitedto dump coal in the business sections during olice hours. lThis required the use of the wagons and men after oiiice hours and necessarily increased the cost of thecoal to the consumer.

The present invention is shown as com- Specification of Letters Patent. Application med February 5, 1909. serial No. 476,205.

' prising a tubular member 5 made of soft pliable materialof great strength yet inexpensive, and canvas or sail cloth has been found satisfactory for such purpose. At the upper end ofthe tube is an annular member 6 that is placed, against the tail board 7 of the wa on 8 and removably secured by any suita le means. The member 6 is shown as having hooks 9 and 10 that engage a bar 11 secured to the wagon. The annular member may have a ring ange 12 secured thereto whose axis is inclined to the plane of the ring plate 6. This ring ange forms a convenient means of attachment of the canvas tube 5 that is preferably circular or slightly oval in cross section.

At the lower end of the tube is another annular member 13 to which the lower end of the tube 5 is secured, preferably in such a manner that when the tube is stretched out the annular member 13 will lie in a plane perpendicular to the plane of the r' late 6. Similar means may be provid or securing the tube 5 to the ring late 13 as by a ring flange 14 also incline to the ring plate, to which the tube is suitably s'e- Patented Jan. 1S, 1910.l

cured as shown. The plate 13 is preferably rections. This will eiectually prevent any dust rising from the coal falllng down into the hole and from the cellar or room below the avement.

I desired the tube 5 may be provided with supporting means to prevent its sa ging or bending from the weight of t e coal passing therethrough. Two rigid supporting bars 18 and 19 are provided on opposite sides of the chute and secured thereto.

This will cause the tube to retain itsv straight form and prevent sagging. These bars are secured at their ends. to the anges12 and 14 res ectively in an suitable manner prefera ly by eye portlons 20, whereby the tube may vary its angle withits attachmg plates at each .end wlthin certain limits yet be rigidly and properly supported.

It will thus be seen that a chute is provided that is readily attached and detached from the wagon, and will accommodate itself to different sizes or shapes of coal holes in the pavement or building, and can also accommodate itself to different angles with the wagon.

The device is comparatively light in weight and thus easily handled, and furthermore it will take up very little space as it is collapsible, and -can be readily placed on top of orA at one side of the wagon.

While the canvas or other material of the chute is not as durable as if made of metal or even wood such material is comparatively chea and the worn tubing can be easily patc ed or quickly and cheaply rreplaced using the same end members and supporting rods. By this means the coal can be dumped into the hole in the pavement at any hour of the day, without causing un necessary and'disturbing noise, and without any dust or particles escaping therefrom.

Having thus described my invention, I claim:

1. The combination of a ring plate, attaching means on the plate, a tube of flexible material such as fabrlc having one end secured to the plate and extending at an an le therefrom, a second ring plate, the tu e having its other end secured to said ring plate and inclined thereto whereby the said ring plates will lie in substantially perpendicular planes when the tube is extended, a rigid supporting rod on each side of the tube secured thereto and having' its ends hinged to the said ring plates respectively, and an annular apron member of flexible material such as fabric secured to the tube n ear its lower end to cover the marginal portions of'the opening engaged by the lower ring plate.

2. The combinatlon of a ring platehavin'g an annular flange at its opening whose axis is inclined to the ring plate, attaching means on the ring plate, a second ring plate having an inclined annular flange at its openin a tube of flexible material such as fabric aving its ends secured to said ring flanges respectively whereby the ring plates will lie in planes substantially perpendicular when the tube is' extended, and su porting rods one on each side of the Luge secured thereto with the ends hinged to the plate members lrespectively.

3. The combination of a. ring plate having an annular flange at its opening whose axis is inclined to the ring plate, attaching means on the ring plate, a second ring plate having an inclined annular ange at its opening, a tube of flexible material such as fabric having its ends secured to said ring flanges respectively whereby the ring plates will lie in lanes substantially perpendicular when t e tube is extended, supportin rods one on each side of the tube secur thereto with the ends hinged to the plate members respectively, and an annular member of flexible material such as fabric se cured to the tube near its lower end to cover the marginal portions of the opening engaged by the lower rin late.
