As the ower end of said ring is secured to the Iniddle portion of part 51 is suitably iitted tothe corresponding tube end of art 44, (see especially Fig. 3,) I am enable by this means to vary the inclination of the straw-delivery tube 'or chute (by manipulation of the device just described) without opening the joint between said

lparts

51 and 44.

The two tube-

sections

51 and 52 are connected by hinge 61 in such manner that the 'part 52 (and the hood and other portions carried thereby) may be folded back onto the separator for storage or transportation. In order that I may do this easily, I attach to the part 52 a gear-rim 62 and mount upon the part 51 (in suitable bearings '63 and 64) a shaft 65, having a pinion 66, which engages with said gear-rim. Said shaft' being provided with crank 67, I ain enabled to operate saidpinion and gear-rim to fold the outer portion over, as will be readily understood. j

The weight of the tube or chute and its associated parts is supported by a rope 71, (see Fig. 1,) which is attached to a suitable eye. 72 thereon and passes thence back over a sheave for pulley 73 on the separator and thence down to a winding-drum 74, provided with a crank 75 andwhich is situated at a point on the lower portion of the separator-frame where it is conveniently accessible and may be easily manipulated by the operator.

The hood at the outer end of the delivery tube or chute is shown as comprising a neck 81, which is revolubly mounted on the end ot the tube member 52, and several sections, as 83, 84,'and S5, which are hingedly mou n ted at 86 and are adapted to becollapsed by pulling on a suitable cord 37, but are held distended when torce is not applied to said cord bya spring 88. The outer hood-sections are reticulat'ed or perforated, as shown, so that the air will escape, permitting the straw to drop on the stack instead of being blown violentl)r thereon bythe force of the blast. '.lhe revolving of the neck S1 (and the parts carried thereby) on the tube part 52 is accomlplished by means of pull-ropes. 91 and 92,

Having thus iully described my said invention, what claim as new, and desire to secure by Letters Patent, is

1. The combination, in a pneumatic strawstacker, with the delivery tube or chute, of a horizontallydisposed fan-housing having a central partition in the form of an annular rim extending inwardly-from the casing, and

a fan the blades whereof are cut away to pass astride said central partition, whereby a double'fan and fan-housing are embodied in a single structure.

.2. The combination, in a pneumatic` stranstacker, of the fan, the fan-housingl a hopper-like structure for receiving th(` straw which develops into a nozzle-like eid. a delivery tube or chute hingedly connected'lo said nozzle-like end, a pivoted segmental rack connected to the structure on one side of the hinge, the housing connected to the structure on the other side of .thehinge, and a pinion mounted in said housing structure and engaging with said segmental rack, whereby said delivery tube or chute may be raised or lowered-said nozzle-like end and the adjacent portion of the tube or chute having a segmental formation and one overlapping the other. `l

3. The combination, in a pneumatic strawstacker, with the fan and fan-housing, of a delivery tube or chute connected to said i anhousing composed of' two parts hingedly j connected together, one of said parts having a curved rack pivoted on said part nl' a point. other than the hinge-pivot and the other having a shaft and pinion engaging with said circular rack, whereby the ont er portion of said delivery tube or chute may be folded over in respect to the inner portion. 4

4. The combination, in a pneunnuic strawstacker, of a fan, a fan-casing therefor extending transversely across the rear portion of the separator, a casing into which the fancasing discharges, achaii-conveyer arranged behind said fan-casing and adapted to convey the chaii' toward the sides, and inelosures leading said cha-ti around the fan-casing from said conveyer to the casing into which the fan-casing discharges.

5. rIhe combination, in a pneumatic strawstacker, of the fan, the ian-casing, a hopper developing into a nozzle-like end, said nozzle-like -end being composed of' sections one revoluble in respect to the other, and a trunk or chute composedroi' sections hingedly connected together and to the nozzle one hinge being provided for purpose ot'vertical adjustment and the other hinge being provided for purposes of folding the outer portion of the chute overfor storage or transportation,l

and means for effecting said hinge movements separately.

6. The combination, in a pneumatic strawstacker, of a fan, a casing therefor having a lower portion. axially extended beyond the ends of the fan, and a chad-chute leading into said extended portion,

7. 'Ihe combination, in a pneumatic stra stacker, of a fan, a casing thereforv having a lower portion extending beyond the ends of the ian structure and surrounding thceyes of the fan, and a chad-chute leading into the extended portions of the tan-casing structure.

8. The eombin ation, in a pneumatic strawstackcr, of a fan having tubular fan-eyes, a casing surrounding said fan ci a greater lOO IlO

length than said fan thereby leaving inolosed I hand and seal, at Crosby, North Dakota, this passages'between the fan and the outer Walls of said casing surrounding the tubularfar'l-` 23d day of January, A.
