PNEUMATIC S'IACKER.

Specification of Letters Patent.

Patented July 11, 1911.

Original application filed April 23, 1910, Serial N o. 557,144. Divided and this application filed October 13, 1910. Serial No. 586,826.

To all 'whom it may concern:

Be it known that I, FREDERICK L. SAT- TLnY, 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, such for example as is shown in my application Serial No. 557 ,144 of which this is a division, and particularly to the chute therefor, which I am enabled to so adjustas to discharge and deflect material from variouspoints in its length, as may be desired, in a simple and expeditious manner, as will be hereinafter more fully explained.

In the accompanying drawings, which form a part hereof, Figure l is a side elevation of a separator with a pneumatic stacker embodying my improvements attached thereto; Fig. 2 a side elevation of a portion of the stacker chute; and Figs. 3 and 4 sectional views of the chut-e as seen from the dotted lines 3 3 and 4 4, respectively in Fig. l.

In said drawings the portion marked 10 indicates an ordinary separator to which a pneumatic stacker straw chamber is attachable in any suitable manner. Leading from the fan l2, mounted in said chamber, is the usual duct, 20, with which my improved chute, 30, communicates. Said chute 30 is non-telescopic, and is vertically and horizontally adjustable, as usual, being mounted on a suitable turntable, as 31, and supported by a yoke, 32, and otherwise5'and adjusted by a windlass, 33, and wormed shaft operated by hand-wheel, 34, in an ordinary and well known manner. The outer under portion of said chute 30 is cut away a considerable portion of its length (Fig. l), and at its lower side I provide a guideway preferably composed of angle-bars, 36, (Fig. 4) having a space, 37, therebetween. In said guideway I place a'slidable bar, 38, having a groove, 38, therein, which bar is movable by an endless chain or cable, 39, attached to a lug, 40, on said bar, and which chain or rope passes about sprockets or sheaves, as 4l, attached to the guideway,`and 42, secured to the chute, and is operable by means of a crank, 43, associated with sheave 42. To the outer end of said bar 38 a pair of arms, 50, are secured, which lie on the outer side of the chute and are preferably connected by a band, 51, to insure their stability, and in the ends of said arms I mount a hood or deflector, 52, which travels along the inside of the chute, being indicated by full and dotted lines in Fig. l in its normal position, and which may be adjusted by means of an arm, 53, to which is attached a cord, 54, running to within convenient reach of an operator. Also connected to said bar 38 I secure a second pair of arms, 55, having rollers, 56, mounted in the ends thereof.

'Io the end of the lower portion of chute 30 I hinge a plurality of hinged semi-cylindrical adjustable iller sections or closures, 60, which are normally dependent from said chute, as indicated in Fig. l. By the employment of the sectional fillers just described I am enabled to readily adjust the stacker chute to discharge the material at different distances from the separator so that the same may be distributed over a considerable area and in such manner as to insure a compact stack, and which I accomplish in the following manner: As stated, the sections 60 (Fig. l), and also the hood or deflector, are shown in normal position, and, when so arranged, material discharging through the chute will instantly be deiiected downwardly upon striking the hood, which lies inside the chute. When it is desired to make the discharge slightly farther out, crank 43 is turned in the proper direction to cause chain 39 to move bar 38 outwardly, during which outward movement the hood or deflector 52, mounted on arms 50, is also carried the same distance, and also, as will be readily understood upon reference to Fig. l, as said bar 38 travels outwardly the arms 55 thereon carrying the rollers 56, against which the upper semicylindrical section GO rests, push each ot said sections upwardly on its hinge, so that when the rollers have reached the outer end ot a section the latter has tilled up the open portion oi the chute to the extent ot its length, as indicated in Fig. 2, and the closed portion ot' the chute becomes accordingly increased, the remainingv sections depending; trom the tirst section in like manner as it depends trom the chute by its hinged connection therewith; and as said bar meets the hinge connecting said sections each hinge becomes seated in groove 8S thereof and is thus prevented trom lateral displacement during' the operation ot closing` or opening,` the chute. in this nianner the cut-away portion ot' the chute can be tilled step by step as the bar 3S is caused to move outwardly, placingone section after another in position, while at the same time the same relation between the outer end ot each section and the de'tleetor is constantly maintained, and when all the sections have been tilled in the chute is substantially a closed tube through its entire length, or to whatever extent said sections have been brought to closing position. lt will be understood also that said sections may be readily returned to dependent or normal position by reversing the direction ot movement oit bar 38, and the cut-away portion ot the chute thus enlarged as desired.

I claim as my invention:

l.
