To all lwhom 'it may concern:

' Be it known that I, ERNST IRoonasna, a citizen of the United States of America, re siding at Alton, in the county of Madison have 'Invented certain new and useful Improvements in .Coal or `Ore `Washers, of .which the following is a full, clear,'and exact descri tion, reference being had to lthe acgompaxg'ing drawings, form part of 'this specification.

My invention relntegfto, means for controlling the discharge ofsate, ore, or other .relatively heavy matters from ^the washing tanks of coal or ore washers after they have washing tanks from been deposited in said the object of the 1nthe jig-s of the washers,

` vention being to provide means whereby sax heavy matters may be discharged separately from each of abattery or series of washers assembled. with each other, and operable in a manner to provide for each outlet being continually in a closed condition.

A. further object 'oiv the invention is to provide for the separate discharge of heavy matters from the several washing tanks independent'of each other, with the object in View of permitting examination of the heavy matters delivered from each tank without mixture of the matters discharged from the several tanks.

Figure l. is a vertical cross section through a washer equipped with my device. Fig. 'lll' is a front elevation o'f the end washer of a battery of Washers. Fig. III. is in part an enlarged vertical section of the lower por-l tion of a washer and in part an elevation ofp my device. Fig.' 1V. is a longitudinal section through the gate of my device, its shaft, and an operating means upon said shat't. Fig. V is a front elevation of my device showing a battery of washers.

In the 'accompanying drawings :-1 designates the jig ot' the washer having an iml purities outlet 2 that is controlled by a gate'.

The jig is supported and reciprocated vertically in any usual manner, such as by the employment of hangers a that are actu ated by eccentrics 5 upon eccentric shafts 6.

.'lhe jig operating means and the means for controlling the impurities outlet 3' of the jig ma be that-illustrated in the drawings, for

which no invention is herein claimed, or any'I other suitable mechanism. y

if designates the washing tank of the washer inV which the jig 1 operates and which is provided with a converging hopper Y 19 is a pawl loosely fitted bottom 8. At the bott-0m of the washing tank is an outlet 9.

10 designates a gate housing of a dischargel valve suitably supported at the bottom ofthe washing tank and which'has an inlet in communication with the outlet 9 of vsaid tank, (as seen in Fig. I.) andis provided with an escape opening 11 at the bottom. 12 is a chute located beneath the escape opening of the gate housing and into which the material that passes through said gate housing may descend to be delivered into a conveyor 13 that may be of any preferred construction.

The body of the gate housing 10 is of approximately cylindrical shape in cross scction and within said gate housingis-a closely fitting chamber-ed controller or segmental gatel/l, (see Figs. I and IV,) that-is adapted .to be rotated in the gate housing by means to be next described. -15 is a gate shaft that extends longitudinally in the gate Ihousing and to which the heads ofthe segmental gate 14 are fixed. This shaft is hori- .zontally arranged and has txed lto it, ex-

telriorly of the gate housing, a ratchet wheel 16. 17 are rocker arms 'the shaft 15 on opposite sides of'and adjacent to the ratchet wheel thereon and in the outerends of which is mounted a rod 18. to the rod 18 and adapted to engage the teeth-ot theratchet wheel 16, (as seen in Fig. III.) 20 is a 'reciprocating operating rod having afork 21 at i'ts .inner end that embraces the pawl 19 and is ivoted to the rod 18 of the rocker arms 17, and through the medium of which said rocker arms are moved backwardly and forwardly to cause the pawl lt) to impart rotation to the ratchet wheel 16, the shaft 15 on which mounted, and the segmental gate 14. 'l at its outer end to an eccentric strap 22 that surrounds an eccentric 23' upon a. driven shaft 24.

It will be seen that upon rotation of the shaft 24 and the eccentrlc thereon, reciprocatory movement is imparted to the o eratling rod 20, and as a consequence o said movement of the operatin rod, the rocker arms 17. are moved to an fro to perform theiinoffice The driven shaft 2a hy which the eccentric 23 is carried is operated by connection tome of the jig operating eccentric shafts 6, the means ein loyed for this connection being`preterab y a sprocket chain loosely itted to operating rod 2Q is connected 25 that operates upon a lower sprocket wheel manner 'with the result 26 on the shaft 24, and an' upper sprocket wheel 27 upon a jig operating'eccentrlc shaft.

In the practical use of a Washer having my improvement incorporated there1n, the jig of the washer is operatedin theusual of causing the heavy matters that are discharged Afrom the jig 'to escape therefrom and to descend into the washing tank. These heavyr matters fall 1n the washing tank to the outlet 9 .infwhichv gedby opening they accumulate to be dischar f the segmental. gate 14. During the operagate is tionwith the inlet at such .outlet mayenter through said inlet.

This shield is adapt-- ed to be moved toward the point of. the pawl 19 by suitable means, such as an arm' 30, I fixed to the shield and it an'. operating rod 31.
