To all whom it may concern:

Be it known that I, FREDERICK A. Wee- NER a citizen of the United States, resldin at Milwaukee, county of Milwaukee, an

State of Wisconsim-have invented new and useful Improvements in Devices for Regulatin the Discharge of Grain-Heaters, of whic the followin is a specification.

My invention re ates to improvements in grain heaters, and it pertains more especiall among other things, to the device for regulating and stopping the flow of grain from the heater. I

Heretofore it has been common to wholly or partially close the discharge openings of a heater with a plurality of cone shaped stoppers, which have been inserted centrally in such openings whereby the grain, when flowing, is caused to pass out in an annular stream around the stoppers, and experience has shown that the esca ing grain, when so controlled, is liable to ecome accidentally stopped or clogged.

e ob'ect of my present improvement is to provi e a stopper which is adapted to close the escape aperture gradually from one side toward the other, whereby the escaping grain is permitted to pass out in a continuous stream and the liability of the same becoming accidentally clogged in the passage, is avoided.

The construction of my improvements are further explained by reference to the accompanying drawings, in which v Flgure 1 represents a side view, part in section, of a heater rovided with my improved mechanism f dr regulating the discharge therefrom; and Fig. 2 is a detail in perspective, of one of the sto pers in connection with a supporting mem er, by which the several stoppers are supported and adjusted in their respective apertures.

Like parts are identified by the same ref erence numerals in both views.

The steam chamber 1, grain duct 2, grain deflector or a itator 3 and discharge funnels 3 are al? constructed substantially in the ordinary manner, and invention is predicated herein more especially upon the arrangement and construction of the device for regulatingand stopping the flow of grain from the receivin chamber 4 as it escapes from the grain tu es above.

5 is the bottom of the heater, which is provided with a plurality of apertures 6,

through which the heated grain is permitted to flow from the heater.

7 are stoppers by which the escape of grain is regulated or stopped at the will of the operator. The several stoppers 7 are supported from the supportin member 8, which is adjustably suspended mm the bottom of the heater 5, by a plurality of suspension screws 9, having screw threaded earings in the stationary nuts 10, while the supporting member 8 rests upon the collars 11 of said bolts. The suspension screws9 are preferably provided with hand bearin s 12,

y which such screws may be turne upwardly or downwardly in the nuts 10, whereby the supporting member 8, together with the stoppers 7 may be adjusted in the discharge apertures 6. The stoppers 7 are provide upon one side with a downwardly inclined concave recess 13, whereby as the stoppers are partially withdrawn from the apertures, the grain is free to escape in a solid cylindrical stream through the space between the concave sides of said stoppers and the o posin sides of said apertures.

It will e um erstood that as said stoppets are raised by turning up said suspension screws, the apertures 6 will be gradually closed from one side, while the grain will be free to pass in a solid stream from the opposite side. When, however, it is desirous to stop the escape of grain, said suspension screws 9 are turned upwardly until the extreme lower ends of the stoppers are brought into the a ertures, whereby such apertures are closed. Thus it is obvious that the escape of ain from the heater may be regulated to ow faster or slower or stopped at the will of the operator by turning said hand screws upwardly and downwardly in their bearings. The bottom member 5 is retained in contact with the lower end of the heater inclosing walls 16 by the central rod 17 and supporting nuts 18, and said rod 17 is connected at its upper end to the upper end of the heater.

Having thus described my invention,

what I claim as new, and desire to secure by apertures for the escape of grainE-a plurality o stoppers havlng a vertical onvex side conforming in shape to and adapted to bear against one side of said apertures, and an opposite downwardly diverging side, said an opposite concave downwardly diverging stop ers being adapted as they are raised side, said stop ers being adapted as they to c ose said apertures from one side and are raised to c ose said apertures from one means for adjustably supporting said stopside and means for adjustably supporting 15 5 pers In said apertures, said stoppers in said a ertures.
