PNEUMATIC STRAW-STACKER.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed August 29, 1918. Serial No. 251,876.

To all whom it may concern:

Be it known that I, FRANK B. CARTER, 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 Straw-Stackers, of which the following is a specification.

My invention relates to improvements in grain saving wind stackers, and consists in certain details of construction and arrange ments of parts whereby I am enabled to readily attach such complete stacker to a thresher or like machine already constructed and obviate the difliculti'es heretofore existing in the labor of making such assemblage.

In the accompanying drawings, forming a part hereof, Figure 1 is aside elevation of the fan drum and associated parts forming part of a grain saving wind stacker; Fig. 2, a perspective of my improved auger casing support; Fig. 3 a transverse sectional view taken on the dotted line 8, 3, in Fig. 1, and Fig. A is a fragmentary plan of said auger casing.

In said drawing, 5, indicates the fan drum, 6, the outlet pipe or boot thereof through which material is discharged into a stacker pipe as usual, 7 the fan, 8, the grain trap, and, 9, the hopper through which material discharging from the grain trap is directed to the auger, 10, the latter being inclosed within'a casing 11, 11.

As is well understood, it is common prac-' tice to ship wind stackers complete to be attached to separators in the field, and also to construct and then attach them to separators in manufacturing establishments. In attaching grain saving wind stackers it is necessary that the auger casing, 11, 11' shall enter an opening made in the ordinary tailings auger casing of the separator, and, as it is customary-to secure the auger to the stacker, considerable difliculty is at times experienced in making a proper fitting to the separator, such fitting involving the labor of lifting the stacker structure to the proper position against the rear end of the separator, accurately marking the tailings auger casing where casing 11 is to enter, then removing the entire stacker and cutting the necessary opening in the tailings auger. As a stacker weighs a thousand pounds or more, according to sizes, it will be readily understood that the work of attachment to supports the anger as indicated, the casing 11 being also secured thereto and to the drum 5.

In carrying out my improvements I provlde a rigid supporting member, A, in the interior of the auger casing 11, adapted to conform to the formation of said casing. Said supporting member comprises a curved portion, 15, an arm, 16, extending therefrom, a cross member, 17 and ears, 18, 19, which support may be a single casting, as indicated in Fig. 2, to be inserted into the end of casing 11, and its trough portion secured to said curved portion 15 by rivets or otherwise inserted through the casing and the holes, 20, in said supporting member. The inner side of said casing, which over.- laps arm, 16, may, together with said arm, be secured to the fan drum 5 by bolts, 21, passing through holes 22 provided therefor.

Said auger casing comprises the two' sec" tions 11 and 11, the latter being telescopically' mounted upon section 11 and adjustably secured thereto in any suitable manner, that illustrated showing a nut 13, secured in section 11, and a slot, 13, in section 11', so that the latter may be shifted longitudinally of section 11, and retained in stationary position, for a purpose to be described herein. The boxing 12 for supporting the auger 10 is of a common type, as heretofore indicated, and is removably attached to supporting member A, so that anger 10 may be readily withdrawn from and inserted into casing 11, 11, the wall, 25, of said boxing being provided with holes which register with holes in ears 18, 19, in member A so that the same may be readily attached to or removed from said member by screws or bolts as is clearly apparent in Fig. 3.

In assembling a stacker embodying my improvements, the boxing 12 and anger 10 may be withdrawn from casing 11 and the stacker frame brought to register with the rear end of the separator and secured thereto. lVhen the exact fit has been determined, the telescopic section 11 of the auger casing can then be shifted forwardly so that its end will contact with the tailings-auger casing of the separator, when the outline or contour of the casing may be marked on the side of said tailings-auger casing, after which, said telescopic section is again shifted rearwardly out of the way so that an opening may be cut or sawed in the tailingsauger casing of a character to receive section 11, whereupon said section is inserted to the desired extent in said opening and fixedly positioned by the nut 13, or other suitable device. Thus the attachment of the heavy stacker is accomplished positively without the necessity of repeatedly lifting and lowering it as hereinbefore indicated; and it may be explained that separators of the many different manufacturers thereof are not standard in sizes or rear formations,

but vary materially, so that a stacker must be especially designed for the numerous types and sizes of such separators. hen the stacker is thus attached, and the casing 11 aflixed to proper position, the auger 10 is inserted in said casing, and, being attached to boxing or hearing 12, is operatively positioned by securing said boxing to the memher A and applying the driving chain or belt, 26, in the ordinary manner.

In the manner described I have overcome existing difiiculties in attaching heavy stackers in the field so that the recipient thereof may conveniently and readily attach the same to a separator without the assistance of expert services and be assured that the same is in perfect alinement and coordmation with such separator; and it will also be understood that in this manner the assemblage of stackers with separators in factories may be simplified and material labor and time conserved.

2. In a pneumatic stacker, means for returning and saving grain comprising a casing and an auger, detachable meansin said casing to which the latter is secured, a hearing to which one end of said-auger is operatively secured, means for connecting said detachable casing supporting means and said bearing, and means for operating said auger.

3, In a pneumatic stacker, an anger ing, a detachable supporting member connected to the end of. said casing and conforming to the contour thereof, an anger in said casing, a bearing for said auger, and means for detachably connecting said bearing to said supporting member.

4. In a pneumatic stacker, an auger casing, a support for said casing comprising a member to which the trough-like portion of said casing is affixed, and a crosspiece connected to said member to which a portion of said casing is afixed.

5. In a pneumatic stacker, a detachable support for an auger casing conforming in shape to the contour of said casing embodying an arm for supporting said casin and having means'by which said casing is secured to said support.

In testimony whereof I affix my signature.

FRANK B; CARTER.
