I THOMAS SLUTZ, OF OROW'LEY, LOUISIANA.
PNEUMATIC- STACKER.
SPECIFICATION forming part of Letters Patent No. 718,395, dated January 13, 1903.
Application filed April 11, 1902. Serial No. 102,341. (No model.)
To aZZ whom it may concern:
Be it known that I, THOMAS W. SLUTZ, a citizen of the United States, residing at Crowley, in the parish of Acadia'and State of Louisiana, have invented certain new and useful Improvements in Pneumatic Stackers, of which the followingis a specification.
In that class of pneumatic straw-stackers in which the straw is fed into the conveyerchute in advance of the fan in such manner that the straw does not pass through the fan difficulty has heretofore been experienced in preventing the straw from being blown backward through the inlet; and the object of my present invention is to produce a structure by means of which the straw can be positively fed into the discharge'chute at a point in advance of the blast-fan and in such manner that by no means can the straw be forced backward through the inlet so as to become choked therein.
The accompanying drawings illustrate my invention. 1
Figure 1 is a vertical section of my improvement in connection with a separator of usual form. Fig. 2 isa plan section on line 2 2 of Fig.
1; and Fig. 3 is a sectional detail, on an en-- larged scale, of the essential elements of my invention.
In the drawings,5 indicates a separator-casing of any desired and well-known form, in
which are mounted the straw-separating rakebars 6 and the grain cleaning screens 7. Communicating with the casing 5, one at each side thereof, are two fan-casings 8 8, each of which is provided with a discharge-spout 9. The two discharge-spouts are led upwardly and inwardly,so as to be brought together into a single discharge-tube 10, which leads upwardly to the single stacker-tube 11. The two fans 8 are of such size as to create the necessary blast through tu bes, l0 and 11, and the eye of each of said fans communicates with the interior of easing 5, so as to receive the chad from the screen 7, the said chaff therefore passing through the fans and being easily distributed to the two fans by means of inclined vertically-arrangeddeflectors 12,which, if desired,maybe hinged at 13,soas to beswung out of the way. Formed in the upper side of tube 10, preferably atabout the point of j unction of the two tubes 9, is an opening 14, to-
ward which leads a hopper 15, the upper end of said hopper lying in position to receive the straw from the rear ends of the rake-bars 6. Located adjacent the upper or forward edge of opening 14 is a feed-roller 16, which is held in stationary bearings and is adapted to be driven in the direction indicated by the arrow by means of suitable pulleys and belts connecting the shaft thereof with a driven portion .of the machine. Supported in suitable hangers 17 from the shaft of roller 16 is a coacting roller 18, which is movable toward and from roller 16, but is yieldingly normally held close to roller 16 by means of suitable springs 19, one of which is shown in dotted lines in Fig. 3. The periphery of roller 18' lies close to that Wall of tube 10 which forms the lower or rear edge of opening 14. The opening 14' at its forward side may be continued to the point a, or thereabout, if desired, the'periphery of roller 16 fitting close thereto; but I prefer to form the forward edge of opening 14 by a lip 20, which follows the curvature of roller 16 and lies close thereto, extending toward the month between the two rollers 16 and 18, as clearly shown in Fig. 3., By this means all possibility of the creation of a current of air between the lip 20 and roller 16 by reason of the blast through tube 10 in the direction indicated by the arrow is prevented. In operation; therefore, the straw passes from the rake-bars 6 in the hopper 15 and is engaged by the-two rollers 16 and 18 and fed positively therebetween into tube 10 at right angles to the direction of blast, the rollers preferably rotating at a considerable speed, so as to project the straw into the tube with considerable force. As a consequence the forward ends of the straws will be positively forced by the point of conjunction between rollers 16 and the Wall of tube 10, so as to prevent the possibility of any straw lodging in said joint, and thus preventing any choking of straw at the entrance.
I claim as my invention-- 1. In a pneumatic stacker, the combination.
with a fan, and a discharge-spout leading therefrom the said discharge-spout having an opening formed therein in advance of the fan, of a pair of feed-rollers arranged outside of the spout immediately adjacent the oppoward edge of said opening, of a pair of feedrollers 16 and 18 arranged adjacent said opening, the lip 20 extending up toward the point of ooaction of the rollers, substantially as and for the purpose set forth.
In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 2d day of April, A. D. 1902.
