CHARLES WALLACE HUNT AND CHARLES C. KING, OE NEW YORK, N. Y.

COAL-CHUTE, ac. A

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application tiled March 6, 1905. Serial No. 248,779.

To a/ZZ Vwhom it may concern:

Be it known that we, CHARLES WALLACE HUNT and CHARLES C. KING, citizens of the United States, residing in West New Brighton, borough of Richmond, city of'New York, State of New York, have invented certain new and useful Improvements in Coal-Chutes, &c., of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to chutes for coaling locomotives and for other like purposes, and

has for its object to improve the construction of such devices in general, and particularly to provide improved means for controlling or cutting olf the flow of coal or other material through the chute, so that the coal or other material may be drawn slowly or rapidly, as may be desired, or the delivery completely stopped.

The invention will be more fully explained hereinafter with reference to the accompanying drawings, in which it is illustrated as embodied in a convenient and practical form, and in which Figure l is a view, partly in Side elevation and partly in vertical section, showing the improved chute applied to a bin, the valve being represented in full lines in position to stop the iiow of coal and in dotted lines in position to permit the free flow of coal. Fig. 2 is a view in front elevation, showing the same parts.

The bin a, to which the improved chute may be applied, may be of any suitable construction and is preferably provided, as shown in the drawings, with a delivery-floor which is inclined toward the mouth or opening o, from which is extended a fixed chute d, with which cooperates the valve or gate which controls the liow of the coal or other material. The valve or gate is preferably supported by the chute d upon a shaft e, which is mounted in the sides of the chute OZ and extending from side to side thereof strengthens the chute, while affording an inexpensive construction. The valve comprises an under gate f and an upper gate g, both supported by rigid arms f and g from the shaft or axis e. The two gates or their supporting-arms may be cast in one piece, if desired, but if not they are' arranged as one piece and are preferably secured to the shaft e. The under gate f is arranged to swing beneath the lower end of the iixed chute 0l, as clearly shown in the drawings,- its arms f being outside of the chute, while the upper gate g is arranged to enter the chute d, its arms g being so formed as to permit this. An operating-arm may be secured to the shaft e and may be provided with an operating rod or handle c'.

.A movable spout lo is arranged to receive and direct the coal or other material delivered by the valve and is preferably hung upon the .axis e of the valve, being provided for this purpose with arms 7c', which permit the spout to hang clear of the end of the chute. Suitable means, such as the block and tackle l, (shown in the drawings) may be provided for the purpose of hoisting the movable spout 7c to a vertical position when not is use.

As will be seen upon reference to Fig. 1 of the drawings, the gate f is preferably curved and hangs Somewhat closely to the under side of the chute CZ, so that it may move readily between the `lower end of the chute and the upper end of the movable spout c. Furthermore, it will be observed that the construction and relation of the two parts of the gate are such, especially with respect to the form of the upper gate g and its arms g', that the center of gravity of the valve is to the left hand of the axis e, whereby the valve tends to return to the position indicated by full lines in Fig. l, in which position theplane of the upper edge of the gate f and the lower edge of the gate g is at an angle with the horizontal not greater `than the angle of repose of the coal-or other material in the chute, whereby the movement of coal through the chute is checked altogether when the valve is in the position shown without requiring the gate g to move down through the coal to the bottom of the chute d. A slight pull on the operating-rod z' increases the angle of the plane which includes the edges of the two gates above the angle of repose of the coal, so that the coal moves slowly past the gate g. The movement of the coal increases with the increase of the angle, and when the valve reaches the position indicated by dotted lines in Fig. l, with the gate j' swung entirely beneath the chute cl and the gate g brought to the top of the chute d, the coal will run freely through the chute. yWhen the operating-rod z' is released, the valve will return quickly to the full-line position and the iiow of coal will be stopped.

It will be understood that details of construction and arrangement may be varied to suit different conditions of use and that the l ity of the valve is carried to one side and the invention is not restricted to the precise form and construction shown.

We claim as our invention- 1. The combination with a delivery-chute of a Valve therefor comprising an under gate and an upper gate connected to swing together upon a common axis, the under gate being arranged to swing beneath and across the end of the chute and the upper gate being arranged to swing into and out of the chute above the end thereof, substantially as described.

2. The combination with a delivery-chute, of a shaft mounted in the sides thereof and a valve therefor secured to said shaft and comprising an under gate and an upper gate connected to swing together upon a common axis, the under gate being arranged to swing beneath and across the end of the chute and the upper gate being arranged to swing into and out of the chute above the end thereof, substantially as described.

, 3. The combination with a delivery-chute, of a valve therefor comprising an under gate and an upper gate connected to swing together upon a common axis, the under gate being arranged to swing beneath and across the end of the chute and the upper gate being arranged to swing into and out of the chute above the end thereof, the upper gate being supported to one side of the axis of the valve toward the chute, whereby the center of gravvalve tends to swing into the closing position, substantially as described.

4. rl`he combination with a delivery-chute, of a valve therefor comprising an under gate and an upper gate connected to swing together upon a common axis, the under gate being arranged to swing beneath and across the end of the chute and the upper gate being arranged to swing into and out of the chute above the end thereof and a movable spout hung from the axis of the valve below the end of the chute and the under gate substantially as described.

5. The combination with a delivery-clmtc, of a valve therefor, a shaft mounted in the sides thereof, an under gate provided with arms by which it is secured to said shaft and arranged to swing beneath and across the end of the chute, said arms being outside of the chute, and an upper gate provided with arms by which it is secured to said shaft and snpported to swing into and out of the chute above the end thereof, substantially as described.

This specification signed and witnessed this 2d day of March, A. D. 1905.
