JOSEPH K. SHARPE, JR., OF INDIANAPOLIS, INDIANA, ASSIGNOB. T THE INDIANA MANUFACTURING COMPANY, 0F INDIANAPOLIS, INDIANA, A CORPORATION OF Y WEST VIRGINIA PNEUMATIC STACKER.

To all whom t may concern Be it knownithat I, JOSEPH K. SrrAR'rE, J r., 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 Staclrers, of which the following is a specification. l

My said invention relates to certain 1mprovements in pneumatic stackers of the character shown and described in my ap- I plication Serial No. 489,056, filed April 10,

1909; and it consists in certain details of construction and arrangements of parts whereby I am enabled to provide a convergent .material-deflecting wall in stackers comprising square materiaLreceiving chambers without modification ofthe frameworkl thereof, all as will be hereinafter more fully pointed o-ut.

The accompanying drawings illustrate my said invention.

Figure 1 is a perspective view of a pneumatic stacker embodying my invention; Fig. 2, a plan; and Figs. 3 and l are detail elevations of portions ofthe material deflector forming part of my invention.

In said drawings the portions marked. 5

represent the usual fan-structure; 6, the ejecting chute; 7 the walls or casing of the material-receiving chamber, and, 8, a fragment of a separator casing. The hopper, 10, is or may be of a concave or other form and preferably horizontally positioned transversely at the lower end of the material-receiving chamber. As fully pointed out in my application hereinbefore referred to, it is necessary that material falling into the hopper be instantly directed into the inuence of the stacker fan; and for this purpose I provide a removable deflector, 11, extending substantially from one side of the rear of the separator, or from the front end of the material-receiving chamber, diagonally across the chamber and hopper to the rear wall of said chamber, by which arrangement, as clearly shown in Fig. 2, said chambe is caused to converge toward its rear s1 e. h

A stacker, when attached to a separator, as will be readily understood, becomes substantially a permanent part of the entire machine; and as it becomes necessary at times to remove sieves or other structures from the separator, which is frequently ac- Speceation of Letters Patent.

complished through the roof above the stacker fan, I provide my improved deflector in removable form, so that it or a portion thereof may be withdrawn, and ample space thus obtained for readily removing the parts mentioned through the side of the chamber at which said deflector is located. In the arrangement shown, therefor, (see. particularly Figs. 3 and Ll), I make the: lower member, 15, of said deflector of a form to lit into the hopper 10, where it may be secured in vertical position in any desired manner, the upper portion thereof being,I preferably reinforced by a strip, 16, or other wise, as may be found expedient. The upper member, 18, of said deflector is supported by a suitable frame, 19 or otherwise, so that it may be securely fitted onto said lower mem-- ber, the wall thereof overlapping said lower member, as indicated in Fig. 3. On the upper side of said member 18 I provide an inclined or coned detlector, 20, preferably secured to a frame, as 20, which may be av permanent part of said upper member, or may be separable therefrom and supported by the casing 7 or otherwise. These members 15 and 18 may be detachably secured together at their meeting ends by the clamping nuts, 21, 21, or in any desired manner, By this arrangement I provide a deflector extending diagonally across the material receiving chamber, as well as an upper delector, as indicated in Fig. 1. The deflector 20, however, may be dispensed with where the conveyers terminating at the rear end of the separator are of a character to permit the extension of the deflector member 18 approximately to the roof of the material-receiving chamber.

As a considerable portion of chaff and light material discharges into the hopper across the reciprocating apron, 25, and to some extent at the side opposite the stacker fan, I provide a de flector, Q6, which may be secured to the separator or deflecting wall in any desired manner, and held divergentV therefrom by a brace, 27, or otherwise, by which deflector such materialis turned toward and into said fan.

While my improved adjustable delecting wall may be applied to a stacker already constructed and having a hopper which extends entirely across the material-receiving chamber, I desire to be understood as not limiting myself to this exact arrangement,

as I may so reduce said hopper in size as to terminate it at itsjunction with said diagonal deector; my object being to so construct said chamber as to insure that material will immediately be directed toward the fan without the employment of conveyers, inclined hoppers, or other specially designed mechanisms.

I claim as my invention:

l. In a pneumatic stacker, t-he combination of a material-receiving chamber comprising a substantially vertical diagonally arranged removable deflecting supplemental wall inclined inwardly from the front to the rear of said chamber, a vertically arranged fan in said chamber at the side thereof opposite to said wall, and a hopper at the lower end of said chamber.

2. A pneumatic stacker comprising a material-receiving chamber embodying a horizontally arranged hopper, a vertically arranged removably attachable deiiecting supplemental wall inclined inwardly from the front to the rear of said chamber and forming the end wall for said hopper, an up* wardly and outwardly inclined deflector at the upper end of said wall, and a vertically arranged fan in the side of said chamber opposite to said deflecting wall.

3. In a pneumatic stacker, a material-receiving chamber comprising a removable diagonallyarranged supplemental wall inclined inwardly from the front tothe rear of said chamber, a fan arranged vertically at the opposite side thereof, a horiZontally-arranged hopper at the lower end of said chamber, and a chaff deiiector adjacent said diagonal wall for directing materialtoward said fan.

4;. The combination, with a separator, of a pneumatic stacker having a material-receiving chamber comprising a vertical defleeting supplemental wall inclined inwardly from the front to the rear of said. chamber a portion whereof is removable to permit withdrawal of structures .from said separator, means for securing said, removable wall portion in position, a fan vertically arranged at the side of saidchamber opposite to said deflecting wall, and a hopper in said chamber communicating with said fan.

5. In a pneumatic stacker, a material-receiving chamber embodying a sectional deiiecting wall inclined from the front to the rear of said chamber, means' for supporting the sections of said wall, means for uniting said sections in the same vertical plane, a fan vertically arranged at the side of said chamber opposite to said deflecting wall, and a substantially horizontally arranged hop per in said chamber communicating with said fan. Y

6. In a pneumatic stacker, a material-receiving chamber having a substantially vertical deflecting wall inclined inwardly from the front to the rear of said chamber, an upwardly and outwardly'inclined deflector at the' upper end of said wall, a fan vertically arranged at the side of said chamber opposite to said deflecting wall, and a hopper in said chamber communicating with said fan.

7. In a pneumatic stacker, a material-receiving chamber having a substantially vertical deflecting wall inclined inwardly from the front to the rear of said chamber and comprising detachable members, an upHK wardly and outwardly inclined deflector at the upper end of said wall, a fan vertically arranged at the side of said chamber opposite to said deflecting wall, and a substantially horizontally arranged hopper in saidl chamber communicating with said fan.

In testimony whereof I afliX my signature in presence of two witnesses.
