Be it knownthat I, JOHN B. MOOUTCHEON, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigamhave invented newand useful Improvements in Attachments for Pneumatic Stackers, of whichthe following is a specification. j

' This invention relates to attachments to pneumatic stackers used in connection with threshing-machines. In a pneumatic stacker or wind-stacker, as more commonly called, the strong draft caused by the blast of air is liable to carry off more or less grain with the straw; and itis the object of my invention to avoid this waste or loss of grain and convey it to a suitable receiver.

My invention consists in features of construction and novel combinations of parts in a wind-stacker attachment for threshing-machines, as hereinafter described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a vertical longitudinal section of my improved wind-stacker attachment. Fig. 2 is a vertical cross-section of the same.

Referring to the drawings, the numeral 1 designates what maybe termed'the inner tube or section of a telescopic chute 2, which comprises also an outer tube or section 3, the one tube being arranged to have a sliding adjustment with relation to the other. On the innermost end of the tube 1 is a collare and in one end of the tube 8 is a collar 5, the said collars 4 and 5 being so disposed as to center the tube`1 in the tube 3 and permit sliding adjustment of the said tubes or telescopic sections without great friction, and these collars 4 and 5 also serve as stops to prevent disconnection of the telescopic tubes when drawn out to full extent. Ata suitable point on the tube 1 is a collar 6, which serves as a stop to limit inward or shortened adjustment of the telescopic tubes. The outer end of the tube 1 is curved downward and has attached theretoan adjustable curved elbow 7, which constitutes the inlet to the telescopic chute and is to be placed insuch proximity to the threshing-machine as to receive the straw that is carried oft by the airblast. To permit adjustment of the elbow 7, connection 8 with the it may have a hinged 189e. serial no. 684,759. dromen.)

lower end of a yoke 9, that is secured to the tube 1 of the telescopic chute.l In the upper end of the yoke 9, above the tube 1, is journaled a pulley 10, to which is attached one end of a rope or fiexible connection 11, which is passed over a guide-roller 12 and secured at its outer end to a lug .1 3 on the farther end of the telescopic tube 3. The guideroller V12 maybe supported above the yoke 9, as shown. By rotating the pulley 10,to which a winch-handle may be connected, the rope 11 will be wound on said pulley and thereby draw together the tubes 1"and'3, so as to shorten the telescopic chute. The outer end ofthe tube 3 is open at its under side to form an outlet 14 for discharge of straw. y To guard this outlet, there is secured to the end of the tube 3a downwardly-curved hood 15, that is provided with an adjustable section 16, which is hinged at 17, as shown.

In most pneumatic stackers considerable grain is carried oif with the straw and can.` not be readily recovered. 'For the purpose of avoiding this waste of grain I have provided meansy for separating the straw from such grain as may be carried with itinto the straw-chute and to conductV the saved grain to a suitable receptacle. As a means for accomplishing this result there is hinged at 18 in one end of the straw-outlet 14 a series of fingers 19, that extend across the somewhat funnel-shaped inlet end 20 of an adjustable grain-spout 21,which is hinged or pivoted at the same point'as saidfingers. The spout 21 is extended backward beneath the telescopic chute 2, and it is adjustably supported at or near its rear end by means of sliding connections 22 and 23, which may consist ofbars or rods connected by a set-screw 24C or otherwise, the upper bar being arranged to have a`pivotal connection 25 with the under side of the main or outer chute-section. The rear-V end of the spout 21 is curved downward to for-m a grain-outlet 2G, through which the grain will be discharged into any suitable receptacle.

In passing out from the chute the straw is deiiected upward toward the top of the tube 3 by means ofthe fingers 19, while any grain i that may have been carried out to that point will fall between 'the said iingers into 4the inlet end of the grain-spout 21 and be there-` by conducted to a suitable receiver. This ICO the same point as the adjustable grain-spout and extended across the inlet to the said spout, substantially as described.

2. In a pneumatic stacker for threshingmachines, the combination of a telescopic straw-chute having an outlet in the under side of its outer end, an adjustable grainspout having its inlet end in communication with the chute-outlet and hinged thereto, a series of fingers hinged at the same point as the grain-spout and extended across its inlet, and adjustable connections between the rear portions of the straw-chute and said grainspout, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

JOHN B. MCGUTCHEON.
