SPECIFICATION forming part of Letters Patent No. 649,051, dated May 8, 1900. Application iilod January 22,1900. Serial No. 2,398. (No model.)
To all whom it may concern:
Beit known that I, JOSEPH A. HAMMAN, of
Bement, in the county of Piatt and State of.
Illinois, have invented a certain Improved Stack-Former to be Used with Wind-Stackers, of which the following is a specification.
This invention comprises a straw-barrier attached to the tube of a wind-stacker and adjustable with relation thereto to an extent` to enable the side of the stack farthest from the thresher to be positively outlined and colnpactly built. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.
IVind or pneumatic stackers are built tol swing both laterally and vertically, and they are provided with adjustable hoods on theirv discharging ends, by means of which the di-y rection taken by the discharged straw may be controlled. They are also usually made extensible, so that their discharge ends mayv be at different distances from the thresher at the will of the operator; but while they are capable of directingthe discharge of the straw quite completely they fall short of building perfect stacks on account of the fact that after f the straw leaves the stacker it is beyond the control of the` operator, the far side of the stack is formed loosely and unsymmetrically,
of my invention, and Fig. 2 is a side elevation of the same.
A laterally and vertically swingable section of a wind-stacker tube is shown at 1, at 2 is shown a telescoping extension of the tube, and an adjustable hood on the discharge end of the stacker-tube is shown at 3. These elements are well known to stacker-men. ,They
tube in front of the discharge end thereof, whereby the straw may be confined in the limits described by the swing of the plate, and the stack may be firmly and symmetrically shaped by sliding action of the plate. C0n= sidered specifically, the barrier-plate9 has its vertical ends 9 turned outward or away from the thresher, so as to form inclines that run freely against the straw asv the plate is swung from side to side and pack it in place. Lugs S are fastened to the upper edge of the plate, near the ends thereof, and they form pivotbearings for the arms that support the plate. The arms or rods comprise rods 6, which are pivotally connected with lugs 8, tubes 5, into which the rods are extended, and larger tubes 4, which receive tubes 5 and which are pivotally connected one with each side of the slidable section of the stackertube. The tubes 5 are preferably fastened permanently in the larger tubes 4, while the rods are held adjustably in the tubes 5 by means of setscrews, one of which is shown at 3l in Fig. 2. Strips 10 are fastened to the inside surface of the plate 9 under lugs 8, rings l2 are slipped yover tubes 5 and rods 6, and iiaps 11 of iexible material are fastened tothe strips and to the rings. The Iiaps are triangular in outline, they terminate in acute angles adjacent to the discharge end of the stacker-tube, and form guides to conduct the straw toward the barrier-plate. Clamp-rings 14 are secured on tubes 5v near the ends of tubes 4, they are connected with the tubes by means ends of the flaps with the collars. Bars 25 -are fastened to the rear or outer surface of the v pivot of the plate, and are provided with lines 26 and 26h, which converge toward the lthresher and merge into a single line 26. The Iiaps 1l connect with the plate below the pivot thereof, and the springs tend to pull the lower edge of the plate toward the thresher. The lines 26n are attached to the plate above the pivot thereof, and a pull thereon tends to swing the lower edge ofthe plate away from the thresher, and so the lines and the springs provide means whereby an operator may inanipulate the lines to vary the position of the plate with relation to the vertical.
'of set-screws 15 and springs 13 connect the IOO Means is provided whereby the plate-carrying arms may be raised or lowered on their pivotal connections with the stacker-tube. Such means may vary to suit different requirements; but I prefer to employ the mechanism shown in the drawings, wherein a rocklever 17 is mounted pivotally on the front end of the slidable section of the stackertube and is connected with the arms that support the barrier-plate through rods 16. An are-formed rack 22 is placed adjacent to the rock-lever, a pawl 23 is pivoted in the lever in position to engage the rack, and a line 211 is connected with the pawl and run over a bearing in the upper end of the lever. The lever has a clamp-finger 27, betweenwhich and the lever line 2G is ordinarily held, and a rope 21 extends from the upper end of the lever to a drum 19. The drinn is journaled in a frame 1S, which is fixed on the front end of the section 1 of the stacker-tube, and it has a crank-handle 20, by means of which it is turned.
rlhe rack and the lever may be attached to old stackers by means of clamp-straps 28, which in this instance are made each in two parts, which are bolted together and to the rack 22. A bar 30 may be bolted between the upper conjunctions of the clamp-straps `to form a pivot for the rocklever 17, and side bars 29 may be .fastened to the sides of the clamp-straps and provide pivots for the side tubes 4.
The specific means used to attach the stackformer to the stacker-tube will vary to suit the different styles of stackers, and it is of little consequence so far as the principle of my invention is concerned. The barrier-carrying arms are to be connected with the slidable section of the stacker, and there are "many ways in which this can be effected; but it is essential that the connection shall `be near the rear end of the slidable section of the stacker, so that the barrier-plate may be raised and lowered to the desired extent with relation to the discharge end of the stacker-tube without swinging materially toward or from a vertical line drawn through such discharge end.
In operating the device the rods 0 are adj usted in tubes 5 to snit the size of stack in' contemplation, and the clamp-rings 111 are shifted and set to give proper tension on springs 13. The drum is turned until the rope is wound up sufficiently to take the weight of the barrier-plate and the arms off the pawl 23, line 24 is pulled to carry the pawl out of engagement with the rack, and the rope 21 is run out until the barrier-plate is near the ground, when the stacker-tube is in its lowest position. Then the shiftable section of the stacker-tube is extended by means of the mechanism with which stackertubes are provided or any suitable means, and the line 26 is pulled back until the plate 9 is approximately vertical and then hitched to the rock-lever. The hood of the stackertube is then adjusted to throw the straw toward the barrier-plate7 and the stacker is swung from side to side until the far side of the base of the stack is built to near the height of the barrier-plate. "lVhcn this is done, the plate is raised, the stacker-tube is shortened, and the stack is brought up to the outer line of the base. Then so much has been accomplished, the barrier-plate is made to slightly overlap the far line of the stack. is adjusted with relation to the vertical, and another layer of stack is completed in the manner described. This is continued until the stack approaches completion, when the plate is permitted to slant toward the thresher, so as to properly round oli? the stack.
The crank-handle of the drum is in easy access of an operator on the thresher, and the rope 2l may be run out or taken up to permit the section 2 of the stacker-tube to slide freely on section 1. The rope 2l and the line 24 have nothing to do while the stacker is in operation, and as a matter of convenience the line may be run onto the drum with the rope, provided sufficient slack is given to preclude the detachment of the pawl byV action of the drum. The line 26 is preferably held caught on the rock-lever g but it may extend to the vicinityof the drum for convenience in manipulation. In this case the drum is attached to a band used to sustain the section 1 of the stacker-tube, andas this band is not so very strong a pair of braceplates BlfL are made to extend from the band and bear against the upper surface of the tube. These plates take the stress of the rope when the barrier plate is sustained thereby and aid the band in carrying the load.
The 'flaps 11 form lateral guides, between which the straw is directed against the barrier-plate.
