Ill

L0 all 1071 0112, it may concern.

Be it known that- 'I, HIRAM B. SAOKETT, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a new and useful .Improveinent in Coal-Screens, of which the following isaspecification.

My invention relates to screens which are used in the transfer of coal from one receptacle to another, and particularly in the un-, loading of it,from a bin or car into bags for It consists of an ordinary open wire screen, but having a hoppe'rat theupper end for regulating the fiowof coal, and a chute at the lower end by which the coal is run into bags, and a cut-off in the chute for stopping the flow temporarily while the bags are being changed.

It further consists of details hereinafter more fully described, and particularly pointed out inthe claims.

Figure 1 is a perspective view of my screen. Fig. 2 is a detail view of the bagging attachment in section, with the cut-off closed. Fig. 3 is a similar view with the cut-off open. Fig. 4 is a plan view of the bagging attachment, the cut-off being closed. Fig. 5 is a sectional view through the upper portion of the screen and hopper.

A represents the screen; B, the bagging attachment; 0, the cut-oif at the top; D, the rod the screen is pivoted upon; E, the hooks by which the opening of the cut-off C is regulated; F, the cut-off in the bagging attachment; G, the handle ofF; H, the hooks which the bag is hung upon.

The operation of my invention is as follows: The coal is poured into the hopper at the top, its flow upon the screen being regulated by gate 0, which may be set at different heights by means of the hooks E, which the rod E engages. If the coal is large or the flow is to be rapid, the gate will be raised, as shown in Fig. 1; but if it' is a fine coal or a slow flow is required it will be lowered to one of the lower hooks. When the flow is to be stopped, it may be closed down entirely.

At the lower end of the screen a device for running. the coal into bags is attached. It

consists of a chute B, having restricted sides B B, by which the coal is gathered together,

which the flow is stopped here at the lower end when the bag is full and is being replaced by an empty bag. The bag hangs upon I and the cut-off F, pivoted in the sides, by

The cut-01f F is hung in the middle of the Y sides upon the'boltsfin such a manner that the gate portion aswin gsabout straight across the stream ofcoal, or it may be located closer I to the bottom of the screen in order that the pressure of the coal above the point of suspension will have a tendency to close it, making the closing down of it an easy matter I even while the coal is running through the chute rapidly. When the accumulation of coal at the chute becomes too great, the cutoff 0 at the top may be closed; but it is in tended that the flow'through this latter shall be just sufficient to fill the bags as fast as they can be put in place and removed by a single operator. Thischute or baggeris bolted into the screen by the bolts J in the sides and may be put into any screen of about this size and pattern.

The angle of incline of the screen may be varied by swinging it upon the pivot D, which is designed to be set into a frame or bracket.

What I claim, and desire to secure by Letters Patent, is-

1. The herein-described coal-screen, consisting of the combination of the screen portion A, the regulating cut-off O, at the top thereof adapted to regulate the amount of coal flowing over the screen, the bagger B, re-

movably attached to the lower end of the screen, the cut-0E F, pivoted in said bagger, and ineans for holding the bag in place, all substantially as shown and described.

2. The herein-described coal-screen, consisting of the combination of the screen portion A, the regulating cut-01f U, at the top thereof, adapted to regulate the amount of coal flowing over the-screen, the bagger B, re- Inovably attached to the lower end of'the screen, the cut-off F, pivoted in said bagger,

and the hooks H, H, in the end of the bagger for holding the bag inplace, all substantially as shown and described.

3. The herein-described coal-screen, consisting of the combination of the screen portion A, the regulating cutoff O at the top thereof, provided with the rod E and hooks E which said rod engages for regulating the height of said cut-off, the bagger B, secured to the lower end of said screen, and the cutoff F, pivoted to said bagger, all substantially as shown and described.

4:. The herein-described coal-screen consisting of the combination of the screen portion A, the regulating cut-off O at the top thereof, the bagger B attached to the lower end, having the sides B, setting within the sides of the screen, and the cut-off F pivoted on the sides of the bagger at a point about
