Application filed October 16, 1908. Serial No. 458,044.

Z '0 all whom it may concern:

Be it known that I, AUGUST RosnNTHAL, residing in West Allis, inthe county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Straw Elevators and Stackers, ofwhich the and ensilage cutters, and has for its principal object to construct a device of this character which shall possess superior advantages in point Of simplicity and general efficiency.

ik further object of the invention is to provide a stacker in which straw and fodder will be elevated and discharged from the stacker by oscillating and reciprocating means provided with engaging fingers. A further object of theinvention is to provide a jointed stacker tube and reciproeating means which may be folded without uncoupling any of the parts.

A further object of this invention is to provide a swiveled stacker which may be elevated or swung to any angle desired without affecting the transmission of power to the oscillating and reciprocating means. \Vith the above, and other objects, in view, the invention consists of the devices and parts, or their equivalents, as hereinafter set forth. In the accompanying drawings, in which the same reference characters designate the same parts'in all of the views: Figurel is a side view of a portion of a threshing ma-; chine provided with the improved elevator and stacker, parts broken away and other parts being in section; Fig. 2 is alongitudinal sectional view of the stacker; Fig. 3 is a transverse sectional view of the stacker taken on line 33 of Fig. 1; Fig. 4. is an enlarged transverse sectional view of the stacker taken on line 4 l of Fig. 1; Fig.

upon the other.

Referring to the drawings, the numeral indicates the discharge end of a threshlng nachine, andll the discharge spout or outlet thereof. A stacker supporting frame lZeXtends rearwardlv from the threshing niachlne andon this frame a rectangular stacker frame 131s plvotally supported by means of a pivotal connection 14: mounted on the, lower portion of said supporting frame, and a yoke 15 depends from the upper portion ofthe supporting frame and is pivotally connected to the top of the rectangular frame.

curved trough 16 is rigidly connected to the lower portion of the rectangular frame by straps 17 and extends beneath the discharge. end of the discharge spout 11 of the threshing machine. This trough is curved concentric, horizontally, to the pivotal connection of the rectangular frame with the supporting frame thus permitting the trough to receive material from the discharge spout in any position of adjustment of the rectangular frame desired. A

.double cranked shaft 18 is mounted medially on the rectangular frame and a stacker 19 formed of an inner section 20 and an outer discharge section 21 connected together by a hinge joint 22 is pivotally connected on said shaft.

A short shaft 23 mounted beneath the upper portion of thesupporting frame 12 is provided with a power transmitting wheel or pulley 2% on its outer end and with a universal coupling 25 on its inner end. Another short shaft 26 mounted on the upper portion of the rectangular frame 18 is connected to the universal coupling at one end and at the other end is provided with a sprocket wheel 27. The corresponding end of the double cranked shaft 18 is provided with a similar sprocket wheel 28 and a sprocket chain 29 connects the two wheels together.

The pivotal connections of the universal coupling connecting the inner ends of the short shafts together are positioned in vertical alinement with the pivotal bolts of the rectangular frame thus permitting the ro tation of the short shafts, even though at an angle with relation to each other, and the operation of the stacker in different positions of horizontal adjustment. Two oscillating bars 30 provided with both rigid and swinging depending material engaging fingers 31 and 32 respectively are connected to the cranked portion of the double cranked shaft at their inner ends and their outer ends are pivotally and slidably mounted in channeled guides 33 forming part of the up: per portion of each tube section adjacent to the hinge oint. Reciprocating bars 34 also provided with swinging engaging fingers 32' depending therefrom are pivoted to the outer ends of the oscillating bars and are adapted to be reciprocated thereby. The outer ends of these reciprocating bars are supported by means of bolts 35 (only one being shown) extending through slots provided in the discharge tube section. The arms 36 which serve to pivotally connect the reciprocating bars to the oscillating bars are curved so that said arm will clear the hinge pin 37 when the stacker is in the folded position as shown in Fig. 7. Pins 38 which extend laterally from the oscillat ing bars and serve as pivotal connections between the said arms and the channel guides are provided with anti-friction rollers 39 to reduce the sliding friction therebetween to the minimum. The ends of the channel guides at the joint of the tube are connected to and supported by means of cross bars 40 which extend across the stacker tube from one side to the other immediately beneath the hinge pin 37.

The ends of the hinge pin 37 project beyond the ears of the hinge portion of the stacker and have mounted thereon hook members tl and to these hook members is connected a bail 42. A rope 4-3 connected to the bail extends toward the threshing machine and between two guide rollers 44 mounted on the supporting frame and positioned directly above the pivotal connection of the rectangular frame thereto. The rope then passes around a small windlass mounted on top of the threshing machine and is the means whereby the outer end of the stacker is raised, lowered, and held in adjusted position. The guide rollers being mounted directly above the pivotal connection of the rectangular frame permits the stacker to be swung horizontally to any .position desired without affecting the ad justment of the height of the stacker end.

The inner end &5 of the stacker is enlarged and the lower portion 41 .6 of this enlargement is curved concentrically to the cranked shaft 18 and partly overlaps the outer end of the trough 16 which is likewise curved so-as to permit the stacker to swing on the shaft 18 without passing from beneath the trough. The swinging material engaging fingers are connected to the bars and their movement limited by means of the shoulders L? and 418 formed by recessing thelower side edges of the bars from said edges to the openings 49 through which the fingers pass and are pivotally connected to said bars. The engaging fingers are formed by passing rods through the openings 49 and bending said rods downwardly in the shape of an inverted U with a part of the stems of the U-shaped rods positioned within the recesses. so that in swinging the stems will engage the shoulders and their movement will be limited. The rigid fingers are formed in the same manner with the exception that the bars are only recessed the width of the diameter of the rods in order to hold them rigidly to the bars. As the fingers connected to the inner portion of the oscillating bars are raised out of the material by the oscillating movement of said bars it is unnecessary to provide. for their swinging up against the bars during the return stroke and they are thereforerigidly connected to said bars. Y

The operation of the stacker is as follows: Material is fed to the stacker in the lower curved end thereof from the discharge spout of the machine to which it is connected by means of the trough. The material will be engaged first by the rigid fingers of the oscillating bars during the downward and forward stroke of each bar and then moved upwardly into the more contracted portion of the stacker tube where it will be engaged by the swinging fingers of the oscillating bars and moved into the path of movement of the reciprocating bars which will further move the material and finally discharge it from the discharge end of the stacker. The swinging fingers of both the oscillating and reciprocating bars will engage the material during the forward stroke and during the return will swing up against the sides of the bars and pass freely through the advancing material. By means of the double cranked shaft, the cranked port-ions of which are opposite with relation to each other, the bars on one side are advancing the material while the bars on the other side are retreating thus providing means for continuously discharglng material from the stacker.

The stacker may be swung around horizontally by means of the pivotal connection of the rectangular stacker frame to the supporting frame, and may be raised or lowered by means of the pivotal connection of the stacker tube to the rectangular frame and the rope and Windlass. The novel arrangement of the trough permits these adjustments without interfering with the feed ing of the material to the stacker tube. By means of the hinged stacker tube and the jointed bars the stacker may be folded upon itself, by turning the cranked shaft so that the joints of the bars are in alinement, for convenience in moving the machine to which the stacker is connected from place to place.

From the foregoing description of the constructlon and operation of the device 1t w1ll be seen that a stacker 1s provlded wh1ch is very simple in construction and efficient in operation and contains but a minimum number of parts.
