PNEUMATIC STRAW-STACKER.
Specification of Letters Patent.
Patented June 23, 1908.
Application filed August 1, 1907. Serial No. 386,648.
To all whom it may concern:
Be it known that we, SHERMAN B. SMITH and HARRY W. SMITH, both of the city of Hamilton, in the county of Wentworth and Province of Ontario, Canada, have invented certain new and useful Improvements in Pneumatic Straw-Stackers; and we hereby declare that the following is a full, clear, and exact description of the same.
his invention relates to pneumatic straw stackers and has for its object the improvethe stacker pipe used in such machines.
The straw stacker according to this invention comprises a fan housing having an opening at one side thereof, a fan rotatably mounted in the fan housing and provided with fan blades having knives on their radial edges adjacent to the opening of the fan housing, a knife or knives cooperating with the knives of the .fan blades, an exit for the fan housing, a rotatable elbow connected to the exit, an adjustable stacker pipe detachably connected to the elbow, means for adjusting the stacker pipe on the elbow to vary the inclination of the former relatively to its horizontal position, means for supporting the adjustable stacker pipe when connected with the elbow, and means for slidably supporting the adjustable stacker pipe when disconnected from the elbow.
For an understanding of this, invention reference is to be had to the following description and to the accompanying drawings, in which Figure 1, is a perspective view of the pneumatic stacker.
Fig. 2, is a section on the line a b Fig. 1. Fig. 3 is a section on the line 0 d Fig. 1. Fig. 4 is a view of the fan showing a modification'of the same. 7
Like characters of reference refer to like parts throughout the specification and draw- IIIgS,
The fan housing 1, having an opening 13, at one side thereof is provided with a bracket 2 having alined bearings 2 in which is mounted a hollow shaft 3, containing the central spindle 3*. Upon the hollow shaft 3, is mounted the fan having fan blades 5. The radialedges of the fan blades 5, adjacent to the opening 13, are provided with knives 6. Upon the spindle 3 adjacent to the knives 6, is mounted a knife wheel 7, to the radial arms of which are fixed knives 8, the edges of which are 0 posed to the edges of the knives 6. On the ollow shaft 3, is mounted a pulley wheel 9, having a peripheral flange 10. On the spindle 3 is mounted a pulley 11, having a peripheral flange 12 adjacent to the flange 10, to prevent the belts moving from one pulley to the other. The pulleys 9 and the belt for the pulley 11 the knife wheel 7, will rotate in the op osite direction to the knives 6. The plane 0 rotation of the knives 8 is in close proximity to is drawn into the fan housing, it will be engaged by the knives and cut into short lengths. The 0 ening 13, rovided in the fan housing for the entry of t e straw is preferably eccentric to the center is found in the field of actual ex erience that the straw is sucked into the fan ousing with greater case than when the opening 13 is concentric with the center. When it is not desired to cut the straw, the pulley 11, may be removed and replaced un-orossed, so that the knife wheel will rotate in the same direction as the fan knives 6'.
When the straw is required to be out into from the pulley 11 and the knife wheel 7 stationarily fixed to the side of the fan housing 1, by any suitable means such as a set screw 7 a passing through the side of the fan housing. When the straw is required in long lengths, theknife wheel 7 is removed from the spindle 3" and an arm 45 is secured to the side of the fan housing. To the inner side of the arm 45 is secured a knife 46 similar to the knives 8. housing, is an ordinary upon which is revolubly mounted the elbow 16. A collar 16 surrounds the elbow 16 and from the collar 16 extend forwardly arms 17 provided with bearings 18 having internal bosses 19. Through the bearings 18 passes the spindle 20. Upon the spindle 20 are mounted the supporting arms 21 for the supporting collar 22 of the adjustable stacker pipe 23. of a circle having for its center the center of the spindle 20. The adjustable stacker pipe 23 is movable over the elbow 16, which is preferably slightly flexible. The joint 23*, at the junction of the stacker pipe 23 and the elbow 16, when the stacker pipe 23 is in approximately a horizontal position, forms an angle of about 85 degrees with the plane of the turn table, and the stacker pipe 23 is of turntable base 15,

that of the knives 6, so that, when the straw i of the fan, as it i the driving belt for i medium lengths, the belt can be removed 1 Fitted to the exit 14, of the fan The elbow 16 is curved in an arc diameter than the elbow arm 35, is a 16, to enable it to slide freely over the latter during its adjustment to its various positions. The movement of the stacker pipe 23 on the elbow 16, is effected by a cord 24, attached to a hook 25 at the upper part of a collar 22 and passing around a manually operable drum 26, rotatably mounted in the standard 27 extending upward from the collar 16 at the rear of the elbow 16. Forwardly extending from the collar 22 is the usual beam' 28, having a manually operable pulley 29 at its inner end, and a pulley 30 at its outer end. Passing round the pulleys 29 and 30, is the chain 31, attached to the outer section 33, of the stacker pipe 23, which, as is usual in straw stackers, is slidableover-the inner section 23 Loosely surrounding the outer section 33, of the stacker pipe 23 isa ring 34 attached to the end of the beam 28. The ring 34, is placed at the point of balance of the stacker pipe 23, when the latter is contracted. U on the bosses 19, of the arms 17, is oscillating y mounted an arm 35 curved to partially surround the stacker pipe 23. The end of the arm stacker pipe 23 and adjacent to the beam 28. Forwardly extending from the top of the bar 36 carrying on its outer end a roller 37. At the top end of the arm 35 is a roller 38, situated in a plane slightly higher than that of the roller 37, and the roller 38 is preferably provided with an actuating crank 38 Passing under the roller 38 and over the roller 37 is a rod 39 pivotally connected at its outer end to the ring 34. The rod 39 is preferably of annular cross section to facilitate its movement on the rollers 37 and 38.
Pivoted at one of its ends, to the bar 36 near the rear end thereof, is a rod 41 having an aperture 42 at its normally lies along the bar 36-as shown in full lines in Fig. 1, but it may be swung over to extend behind the bar 36 as shown in dotted lines Fig. 1. Bolt apertures 43 are formed through the standard 27, so that the rod 41 can be connected to the standard 27 by a bolt 44 passed through the apertures 42 and 43.
" Then it is desired to turn the stacker pipe bearings 18.
23 in a limited space, as might become necessary, for instance, when the straw stacker was being used in a barn or like restricted space, the stacker pipe is collapsed as much as ossible, the rope 24 is slackened until the enc 23 of the stacker pipe can clear the outer end of the elbow 16, and the rod 41 is swung over and connected to the standard 27 by a bolt 44 which passes through the aperture 42 and one of the bolt apertures 43. The cord 24 is then disconnected from the hook 25 and lastly the spindle 20 is removed from the Then the spindle is removed the only function of the arms 17 is to support the lower end of the curved arm 35, the upper end of which is retained in position by the rod 41, and the collar 22, which normally 35 is situated above the other end. The rod 41 supports the inner end of the stacker pipe, is
free to turn in any direction to clear the elbow. The stacker pipe 23 and its outer section 33 are now only supported by the ring 34, which as stated above, is placed at the point of balance of the stacker pipe when the latter is collapsed. The ring 34 is only supported by the rod 39 capable of longitudinal movement between the rollers 37 and 38 and being of circular shape in cross section, also capable of an oscillating movement about its own axis to enable the ring 34 and stacker pipe to be turned outwards from the arm 35. This movement permits the stacker pipe 23 to be rocked sidewise, and until its inner end, moving towards the left, Fig. 3, clears the end of the elbow 16. The stacker pipe can then be pulled inwards, the rod 39 sliding over the rollers 37 and 38, until half the stacker pipe extends on either side of the turntable, the space required for turning the stacker pipe being thus reduced by one half of its length when collapsed. The turntable can then berotated until the elbow 16 points x H in the direction towards which it is desired that the stacker pipe should extend, and the above proceedings reversed, the stacker pipe being ultimately set up in the desired position.
