Warren STATES PATENT OFFICE.

JOSEPH K. SHARPE, JR., OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE INDIANA MANUFACTURING COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION OF WEST VIRGINIA.

PNEUMATIC STACKER.

Specification of Letters Patent.

Patented Aug-9, 1910.

To all whom it may concern:

Be it known that I, JOSEPH K. SHARPE, J12, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following is a specification.

My invention relates to improvements in pneumatic stackers, and particularly to the chute thereof, which I so arrange as to permit the escape of a large portion of the discharging air blast before it reaches the hood or deflector, to insure that the material will not forcibly strike the latter but will be discharged gently therefrom, and in which chute I also provide means by which the material may be so deflected as to travel along the upper side of the hood and be discharged in a compact stream from the outer end thereof without scattering through the en tire area of the mouth of the hood which, under some conditions, would be the result when the air blast has been separated from the material.

In the accompanying drawings, which are made a part hereof, Figure 1, is a side elevation of a pneumatic stacker chute embodying my invention; Fig. 2, a longitudinal sectional view of said chute, and Fig. 3, a transverse sectional View on the dotted line 3-3 in Fig. 2.

In said drawings the portions marked 10 indicate the chute to which a hood or deflector, 11, of any approved character may be attached. In the upper side of said chute, I provide an opening from which I extend the inclined side and end walls, 12, 13, as indicated in Figs. 1 and 2. Preferably longitudinally of said opening I place a series of bars, or grating, 15, for a purpose presently to be explained. At the bottom of said chute I provide an adjustable deflector, 20, which may be pivoted in any suitable manner, as to a bracket, 21, and which deflector I provide with an arm, 22, to which a rope or cord, 23, may be attached and passed around a sheave, 25, attached to said chute, the end of said rope extending to a point within convenient reach of the stacker operator. Preferably in front of said deflector 20, I provide a shield 30, which overlaps the lower end of said deflector to prevent material from collecting thereunder, the

latter lying normally along the bottom of the chute substantially as indicated by the dotted lines in Fig. 1.

In operation, as the material is being discharged through said chute by the air blast, said deflector 20, may be raised or lowered by pulling upon or releasing rope 2?), the raising of which deflects the air blast upwardly and through grating 15, while the material, having been separated from the air and deflected toward the upper wall of the hood, flows with materially reduced speed along said upper wall and is deposited in compact condition upon the stack, as hereinbefore indicated.

I claim as my invention:

1. A pneumatic stacker chute having an opening in its upper side adjacent to its delivery end for the discharge of air, a grating spanning said outlet for preventing the escape of material therethrough, and a deflector within said chute for deflecting air through said opening and directing the discharging material separated from the air substantially along the inner upper side of said chute beyond said opening and through terial is discharged at reduced speed.

the delivery end thereof whereby said ma- 2. A pneumatic stacker chute having an opening in its upper side adjacent to its delivery end for the discharge of air, walls surrounding said opening, a grating within said walls and spanning said opening for preventing the escape of material therethrough, a hood at the outer end of said chute, and a deflector within said chute for deflecting air v through said opening and directing material separated from the air along the inner upper side of said hood whereby said material is discharged at reduced speed. j,

'3.A pneumatic stacker chute having an' air discharge outlet adjacent its delivery end,

a hood at the delivery end of said chute, a

shielded adjustable deflector within said chute for directing air through said outlet and material through said hood, an arm attached to said deflector, and means connected with said arm for raising'and lowering said deflector.

4:. A pneumatic stacker chute having an air discharge outlet adjacent its delivery end,

a grating over said outlet, an adjustable d eflector in said chute arranged to deflect air through said outlet and material toward the delivery end of said chute, and means connected With said deflector for adjusting the same;

5. A pneumatic stacker chute having an air discharge outlet adjacent its delivery end, Walls surrounding said outlet, a grating over said outlet to permit the escape of air and prevent the discharge of material therethrough, an adjustable deflector Within said chute arranged to deflect air through said outlet and material along the inner upper side of the delivery end of said chute, an arm connected to said deflector, and flexible means connected to said arm for adjusting said deflector.

In testimony whereof I aflix my signature in presence of two Witnesses.
