T aZZ whom it may concern.-

Be it known that we, MARSHAL T. REEVES, JOHN N. KAILOR, and HARRY O. CLAY, citizens of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented anew and useful Pneumatic Stacker, of which the following is a specification.

Our invention relates to an improvement in pneumatic stackers.

The objects of our invention are to produce an improved form of hood for the delivery end of a stackeretube; to provide improved means for operating said hood, which means shall be independent of the longitudinal move ment of the tube which carries the hood; to provide improved means for operating the outer telescoping end of the discharge-tube, and to provide such other improvements as shall be pointed out and claimed.

The accompanying drawings illustrate our invention.

Figure 1 is a side elevation. Fig. 2 is a vertical section on line 2 2, Fig. 1. Fig. 3 shows the shape of the several sections of sheet metal used in the construction of the hood. Fig. 4 is a central vertical section of the discharge-tube, the hood being omitted. Fig. 5 is a detail from the under side.

In the drawings,-7 indicates a gear which forms the revoluble base of the stacker, and to this is secured an arc-shaped tubular sec tion 7. Mounted upon gear 7 are two arms 8, to the outer end of each of which is pivoted an arm 9. Between the outer ends of the arms 9 is the inner arc-shaped end 10 of the tube 11, the said end telescoping over the section 7 in the usual manner. Telescoping over the main tube 11 is a tubular section 12, the said section being supported by means of a pair of rollers 13 and 14, carried by the upper side of the section, and a similar roller 15, carried at the inner end of the under side of said section. Rollers 13 and 14 rest and 0p crate in a chann'el16, carried along the upper side of tube 11 and extended somewhat beyond the outer end thereof, as shown in Fig. 4, and roller 15 rests within a similar channel17, carried upon the under side of tube 11.

Rollers 14 and 15 are preferably vertically adjustable between a pair of slotted cars 18. For the purpose of moving tube 12 back and forth upon the tube 11 a Windlass 19 is mounted between arms 9 and provided with a suitable handle or crank 20. Secured to the windlass 19 is one end of a cable 21, the said cable passing from the Windlass through an eye 22, carried upon the inside of the inner end of the tube 12, to which it is secured. The cable then passes forward and around a pulley 23, mounted upon the under side of the outer end of tube 11 and from there back to a collar 24, secured to and forming a part of the Windlass l9. Collar 24 is rotatably adjustable upon the Windlass and is held in any desired position by means of a set-screw 25. By rotating collar 24 upon the Windlass the tension of the cable 21 may be easily and quickly adjusted. V

The outer end of the tube 12 is preferably beveled, and secured upon opposite sides thereof, near the outer end, are two brackets 26, to which are pivoted the lower inner cor- 11ers of the first hood-section 27, which is substantially semicylindrical in cross section, the lower ends of said section, however, being shorter than its middle. Pivoted to the outer corners of the section 27 is the second hood-section 28. The inner edge of the section .27 is preferably bound with a strengthening-band 29, which is extended beyond the pivot to form an arm, to which is attached one end of a spring 30, the other end of said spring being secured to the tube 12. Itwill be understood, of course, that the spring 30 is duplicated upon the opposite side of the hood section. strengthened by a band 31, which is extended outside the pivot, and to this extended end is secured one end of a spring 32, the other end of which is secured to the extended end of band 29. Secured to the upper side of band 31 is a cord 33, which is passed back through an eye 34, carried by the tube 12, and secured to a winding pulley 35, mounted upon a stud-shaft secured to the side of the inner end of tube 12. Mounted in suitable bearings near pulley 35 is a worm 86, which meshes with a gear 37, carried by said pulley. form 36 is provided with a polygonal axial open- The inner end of section 28 is also reeted at all of the angles desired.

ing, through which passes a polygonal shaft 38,'the inner end of which is supported in a bearing 38, mounted upon the tube 11, and the outer end of which is supported by a bearing 39, carried by tube 12. For the purpose of forming a long bearing for the outer end of shaft 38 a sleeve 30 may be mounted between the bearing 39 and the bearings of the worm 35. This sleeve 39' is rotatably mounted within its bearings, so that it rotates with the shaft, but is longitudinally movable upon said shaft. Secured to the inner end of shaft 38 is a suitable hand-wheel 40, by which it may be rotated.

The springs 30 and 32 tend normally to throw the two hood-sections into the positions shown in full lines in Fig. 1, and in order to limit the outward movement of each of said sections an eye 41 is secured to the upper side of band 29. Pivoted in this eye is one end of a rod or wire 42, the other end of which passes through the eye 34 and is provided with a head 44. Pivoted to the outer end of rod 42 or to the eye 41 is the inner end of a second rod or wire 45, the outer end of which passes through an eye 46, carried by the band 31, and is provided with ahead 47.

It is Well understood that it is not new to form a hood for the discharge end of a stackertube of a series of semic'ylindrical sections pivoted each to the section immediately preceding; but in all of such constructions it has been found very difficult to provide an arrangement by which the straw could be di- In the present construction we are enabled, owing to the peculiar shape of the hood-sections and by the use of but two such sections, to direct the straw atany angle between a line drawn through the axis of the discharge-tube and a line drawn at least one hundred and thirtyfive degrees from said line toward the rear. In other words, supposing the hood-sections to be in the position shown in full lines in Fig. 1, the straw may be thrown back toward the separator at an angle of from forty-five to thirty degrees from the horizontal. In order to accomplish this result, the two sections of the hood are formed in the following manner: The section 27 consists ofa single piece a, of sheet metal, of substantially the shape shown in Fig. 3, the said piece having the two converging straight edges a and (1, and the curved edges a and a, the edges a and a being designed to form the rear and forward edges, respectively, of the completed section. Running in from the edge a are three parallel slits, forming apair of tongues a and 0. When the piece a is bent into shape, the outer edges of the two tongues are lapped over the adjacent portions of the sheet, and the adjacent edges of the two tongues are also lapped, thus forming in the completed section the hump or bend a The section 23 is formed of the three sections b, c, and d. Thep'iece b is somewhat similar in shape to the piece aand has the two converging straight edges I) and b the curved edge 6 along which the band 31 is to be secured, and the curved edge Z). Cut in from the edge I) are three parallel slits, forming the tongues and 19 similar to the tongues of the piece a, and which are overlapped in the same manner to form the hump Z2 The piece 0 has the two converging

straight edges

0 and 0 the curved edge 0 and the straight edge 0 The piece d is bounded by the two convex edges 01 and d In forming the section 28 edges 5 and c are riveted together, and the edges 0 and (Z are also riveted together. \Vhen thus placed together, the edges 1), c, d, 0 and 12 form a U-shaped line (shown in Fig. 2) which in side elevation is substantially a straight line, as shown in Fig. 1. By this arrangement the piece (1 forms a snout for the end of the outer section.

In order to move the tube 12, the operator grasps crank 20, and by turning it in the desired direction the tube may be thrown forward or drawn back. If there is any slack in the cable 21, it may be taken up by loosening screw 25, turning the collar 24:, and resetting the screw. As the tube 12 is moved back and forth the worm 36 slides freely over the shaft 38, so that the movement of said tube in no wise affects the hood-sections 27 and 28. To adjust the hood-sections, the operator turns hand-wheel 40, which, through the shaft 38, worm 36, gear 37, and pulley 35, operates to wind or unwind the cord 33. In throwing up the hood-sections from the'position shown in full lines in Fig. 1 the first pull on cord 33 swings the outer section 28 upon its pivot until it lies in the position indicated in dotted lines at 50, the upper inner edge of said section coming into engagement with the section 27. A further pull upon cord 33 swings the two sections together about the pivot of section 27 until the whole may be swung up into the position indicated in dotted lines at 51,the snoutd of the section 28 then lying above the medial or axial line of the tube 12.

It will be noticed that the tube 12 is free to move back and forth upon the tube 11 without disturbing the adjustment of the hoodsections and that the two tubes 11 and 12 may be swung as a whole about the pivots of arms 9 without affecting the positions of the hood-sections and without affecting the relative positions of the two tubes.
