APPARATUS Font LOADING coAn To all whom it may concem;

Be it known that I, F ANK E. MUELLER, a citizen of the United States, residing at Chicago, in the county of Cook and State-of Illinois, have invented a certain new and useful Improvement in Apparatusfor Loading Goal, of which the followi'ngis a specification.

My invention relates to a process and apparatus for screening and delivering coal, and particularly to a process for screening, grading and delivering coal direct to the railroad car without dropping the coal and submitting it to the inevitable breakage caused by the usual drop from the graded coal bin to the car. I

One object of my invention is to providea means and process for separating coal into other suitable mechanismactuated from a power source not herein shown.

C is the de livery hopper D, adapted to deliver screena number of grades and for feeding such grades, selectively to a car on a track adjacent or beneath the bins. Another object.

is to provide means for carrying out the process above outlined at a maximumspeed and with a minimum number of bins. An-

other object is to provide a means and process for conveying the coal from the bin gate and downwardly to the car rapidly but without breakage. '(lther objects will appear from time to time in the course of the specification. j

Application filedAugust 7, 1922. Serial No. 580.651.

A is any suitablenform of conveyor or elevator for conveying coal from the tipple or coal source to the 'screens through the opening A in the house A.

B are bin-walls supported by the vertical frame elements B B are the bin bottoms having inclined-sides as at B leading to.

gates B with suitable opening and closing elements not shown in detail and adapted to be controlled bythe chains B 'or otherwise. B .is-any suitable trimmers walk.

' C C? are shaker screens mounted on the oscillating elements (1?, the lower ends of which are afiixed to the frame or support C The shaker screens are "reciprocated in anysuitable manner-,1i0r example by the links C C pivoted adjacent the end of each boom and oscillated by theeccentrics C or any Beneath the shaker screen D adapted -to deliver coal selectively to neighboring bin's. Beneath the lower portion of the screen C is another delivery spout D shown as delivering coal to a Spiral Chute D" in the central bin of the five illustrated in. Fig. 1. w

Mounted beneath the lower end of the shaker screen G is apicking tableE, which is illustratedin Fig. 1 as an endless carrying belt. Thematerial delivered from the outer end of the picking table passes down the chute E and may be selectively deliveredj'down the .spouts E E to the spiral chutes E E delivering to the two bins shown at the leftof Fig. 1.

It will be understood that the various bins overlie the railroad track G, as shown, for example, in Fig. 2, the gates B lying substantially along the central axis of the track. Beneath the gates, and spaced above the track a suflicient distance to permit the passage of cars,'is the conveyor G illustrated in Fig. 1 as an endless belt, the details of which' form no part of the present inven-v tion. This conveyor delivers coal to a rev ciprocating screen G which is osoillat ed'by endless'i-conveyor G1 is replaced by a mlity the link G through any practical eccentric drive mechanism G Adjacent the screen G is the reciprocating loading boom G adapted to be reciprocated by the link Gr driven by the eccentric G The loading boom is pivoted, and any satisfactory means, not herein shown, are used for supporting, raising and lowering at will the outer end of the boom, without breaking the loading contact with the screen G The fines which pass through the screen G drop into the hopper H, and are gathered andiiarried by a spiral conveyor H, which delivers to the screenings elevator H which in turn discharges them through the spout H into the slack bin shown at the right hand of Fig. 1. The slack bin may be provided with a slack gate, and a chute H direct to the underlying car, and of course positioned slightly to one side of the conveyor G lln the variant form shown in Figs. 5 and 6, K is an inclined lip or other form of screen which receives material from the conveyor G and feeds to the apron loading boom K, the details of which do not form part of the present invention. Otherwise the installation is identical with that shown in eform shown in Figs. 7 and 8, tihe' P 'ofsuperposed conveyors L D, adapted to'lb neciprocated in opposition by any suitable. reciprocating means diagrammatically illiistrated as at 1U. L is the loading con- "veyorflwhichreceives material discharged from? any of the storage bins and delivers it tothe loading-boom L hinged atthe 401w i for. raising, lowering and supporting the outer or left-hand end of lb, as shown in ig." 7. Any suitable means may be used outer. end of the hinged boom. The loading conveyor is provided at any-suitable point, as, for example, at L in Fig. 8, with a rescreen, which deposits the fines or degradation on the lower conveyor L, which in turn conveys it from left to right, as shown in Fig. 7, depositing it finally in the hopper L ,,w ence it is carried by the spiral screenings conveyors L L to the screenings elevator H for delivery to the slack bin.

Tn the variant form shown in Figs. 9 and 10, the chutes M, M M M and M deliver coal to the upper loading boom N, down which it passes to the lower loading boom N the two loading booms being recipro- The lower boom N lit will be understood that while I have illustrated several practical applications of my invention many changes might be made in the number, size, shape and disposition of parts, and many combinations and changes in order of the steps of my process might be made, without departing from the spirit of my invention.

The use and operation of my invention are as follows: v

Goal is delivered .by any satisfactory means from a tipple or other coal source to a shaker screen or a succession of shaker. screens, by which the coal .isgraded' and passes through the various meshes or finenesses of screen to a plurality of classified storage bins, of which five are illustrated in the drawings. The material which passes over the screens may, if desired, be picked and is subsequently passed forward over the picking table and into classified bins. I

so arrange the receiving hoppers screens and the delivery chutes that any class of coal, or coal from any particular screen or section of screen, may be delivered at will to more than one classified stora e TlOilZL Tr nece sary, telegraph or spiral c utes' may be provided to deliver coaldownward to the bot tom of the bin, to avoid breakage. In the in the form shown in Fig. l delivers the coal 3 to the rescreen G where the degradation is removed and the coal in its final, cleaned condition is delivered down an oscillating or shaking loading boom which lowers the coal without breakage and feeds it directly to the car bottom. The fines may be disposed of in any suitable manner but are quently returned to a screenings elevator, which eventually" drops them back into the slack bin.

in the form shown in Figs, 5 and 6, for a shaker loading boom an apron loading boom is substituted and a highly inclined lip screen is shown, but the general operation, of course, is the same.

In the-form of Figs. 7 and 8 T substitute for the endless conveyor a plurality of superposed shaker booms or conveyors which reciprocate in opposition, the upper con veyor having at one or more points rescreen which delivers fines or degradation to the lower conveyor, the lower conveyor delivering them to a screen conveyor or elevator. A loading boom is hinged to the upper loading conveyor and, of course, serves to ing boom, which in turn delivers direct to the car. InFigures 9 and I illustrate a 1.0 plurality of chutes delivering coal to an down which it passes to a lower boom N f Y. the booms 'or'conveyors being separately reciprocated by the links N N The sepaupper boom or reciprocating conveyor,

' -rate or lower shaker boom N delivers the material directly to the car. i
