Application iilecl April 16, 1896. Serial No. 587,833. (No model.)

T all whom t rml/y concern:

Be it known that I, WILLIAM N. SPRING ER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Pneumatic Stackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation showing a portion of a threshing and separating mechanism and also my improved straw-stacking devices. Fig. 2 is a vertical cross-section on the line .r ir, Fig. 1. Fig. 3 is a horizontal Section on the line y y, Fig. 2. Fig. fl is a vertical section on the line .a s, Fig. 2. Fig. 5 is a sectional view on the line 5 5 of Fig. 1. Fig. 6 is a similar vienr on the line 6 6 of Fig. 1. Fig. 7 is a sectional view taken on a line near the inner end of the discharge-duct- Fig. 8 is a sectional view on the line 8 S of Fig. 1. Fig. 9 isa longitudinal sectional view through the vertical duct connecting the fanchamber with the discharge-tube. Fig. 10 is a detail view of the connection between the adjusting threaded rod and the parts acting therewith for varying the elevation of the stacker-duct. Fig. 11 is an elevation of the rear or inner curved section of the deliveryduct. Fig. 12 is a sectional view of a portion of the guiding devices for the rear portion of the section M of the delivery-duct. Fig. 13 is a detail perspective view of the chait and dust deector and means for supporting the same. Fig. 14 is a longitudinal section through the outer portion of the stacker spout or trunk and the inner portion ofthe deflectorhood thereon.

In the drawings, A indicates a 'portion of the casing of a separating mechanism at the rear end. The thresher parts and the separating devices proper may be of any suitable sort. As shown, the straw is nally delivered from the table ll ready for withdrawal from the machine.

At 3 is situated the winnowing shoe and fan.

In the rear end ot' the casing there is constructed a hopper-like receptacle which receives the straw from the table B, this receptacle having the rear end wall a, the curved top a', the side Walls a2 and as, and also interior sloping or inclined walls a4, a5, and a". Preferably that portion of the rear Wall indicated by a7 is hinged at a8, so that it can be swung outward more or less as desired and for purposes to be described.

The fan is indicated as a Whole by C. It is mounted in a casing C', which is situated at the side and outside of the separator-casing A. The fan-casing is constructed with an inner plate c, a peripheral wall c and an outer plate cadapted to b e fastened securely, and a removable outer plate c3. The plates c c2 and the peripheral wall c' are fastened together by the bolts c4, which are also utilized to secure them to the framework. The detachable plate cS is utilized to support the fan. The latter is mounted on a shaft C2, which is held in a bearing at O3, cast with the said plate. A second bearing is provided at()4 by a bracket C, which is bolted in place, as shown in Fig. 1. Between the bearings C3 and C4 is situated the driving-belt Wheel D. The shaft O2 projects through the bearing C3 far enough to carry the fan. The latter comprises the hub part c5 and the wings c, the hub having a disk-like plate c7 with ribs cs, to which the wings are riveted.

The fan is not arranged centrally in the chamber O6, but eccentrically, its axis being considerably above and behind the center or axial line of the fan-chamber.

The fan is provided with two eyes or en-I to the ordinary fan-eye, but that at E being i at the bottom of the fan-chamber. The purpose is to deliver to the fan the straw from the separating-table and the chaii, dust, dac., from the winnowing-shoe in two independent masses.

G is aout-off shield or partition of the shape shown in Figs. 2, 3, and 4E. It has the lower horizontal part g, the curved vertical part g',

and the upper inclined part g2. The parts g g are connected to the fan-casing on a line adjacent to and around the upper eye E. They extend across the machine to the opposite wall of the separatorchamber. The upper part g2 of this shield or partition also extends across to the opposite wall and has its forward and upper edge as close as possible lto the table or floor below the straw-carrier .rectly to the upper fan-eye E.

The straw which isr delivered from the carrier B drops behind the shield or deflector G to the bottom of the receptacle above described. From this receptacle it is taken in through the eye or aperture E atthe bottom of the fan-casing. To insure the advance of the straw to the casing, I prefer to employ positively-acting mechanism. I have shown an endless carrier I-I, mounted upon rollers h h', one in close proximity to the aperture E and the other near the opposite wall of the casing. rlhis conveyer may be an ordinary canvas carrier with cleats or chain-belt with attachments or other suitable device. It is driven by a gearing at H', actuated by the shaft h2 and belt-wheel h3.

There will be more or less tendency for the air tov be drawn in through the eye E; but owing to the peculiarities of the present construction there will be a reduced draft, partly 4o Abecause of the fact that the air-currents from the winnowing e fan are mostly delivered through the upper eye E and partly because of the fact that the constant advance of straw will tend to keep the eye E more or less closed. To compensate for this, the positively-acting carrier is employed,which insures a continual advance of the straw into the lower part of the fan-chamber. The currents of air are powerfully propelled upward by the fan, and these currents, together with the fan-plates, acting positively as an ejector, will cause the straw to. pass continuously upward through the inner side of the casing and the duct at I. If at any time it is necessary to still further lower within the receptacle the pressure of the air from the winnowing-fan, this can be done by dropping the above-described doorlike section a7 of the rear wall and supporting it either by hooks or hangers at a, which permit it to be adjusted as desired. By low- Vering this part a7 to the fullest extent access the said shield or deflector is in the embodiment of the invention herein illustrated connected to and supported by supporting-bars g5, which are fitted to guides gs, formed on the side walls a2 a3 of the aforesaid casing at the rear of the thresher. The forward ends of the guide or supporting bars g5 are connected directly with the said shield, while braces g7 are interposed between said bars and shield near the rear end of the bars.

The uptake-duct I is not mounted stationarily, as has been customary in machines of this class, but rotates with the upper or delivery part of the duct and is mounted and supported as follows: The cross-girthsA5 and the frame are extended out some distance beyond the separator-casing, and upon the extended partsfis placed a table-ring A, these parts thus forming a centrally-open frame. This frame is strengthened by downwardly and inwardly inclined braces A7. The duct I is fitted in the tube C7, which terminates the delivery part of the fan-chamber and arranged to rest on the same. Its upper end is in the framework above described and is held in place by means of a series of rollers J, which arc mounted on bearings attached to the framework. The deliveryportion of the duct is formed in sections. The inner section isa short curved pipe K. At its lower end it is rigidly secured by rivets or otherwise to the upper end of the'duct I, preferably by means of a fianged ring L, interposed between them and secured to both. This ring is shown in Figs. l, 2, 4, and 9 and is formed with geared teeth. Horizontal reciprocation can be imparted to it in the usual manner and to the devices connected with it. The ring constitutes a table-like carrier both for the duct, the adjustable parts, and the adjusting devices which actuate them. The delivery-duct proper consists of the inner section M and the outer section M. ally joined, so that the outer one can slide longitudinally along the inner one tolengthen or shorten the total duct. Near the inner end of the inner section M there is a ring N.

These are telescopic IOO IIO

It carries an upwardly-projecting arm N. To

this is fastened a guide-iron O, preferably T- shaped in sections.

l? is a ring at the inner end of the section M. To it there is secured a rod 19, which extends upward and forward, as shown, and is attached at its upper outer end to the aforesaid guide-iron O. Q Q are rods extending also from the ring P to higher points, and at their upp'er ends they are connected by a cross-bar q, to which is connected or with which is formed the swinging nut Q'.

R is astay and truss rod which is connected to the cross-rod q and extends forward and downward to a suitable point of attachment to the guide-iron O.

S S are standards which rise from the rotary support above described, and S S are bracerods which extend forward and downward from the upper ends of the standards S S.

At t there is a pivoted bearing in which there is mounted a screw-shaft T. The latter passes through the nut Q and is provided with a hand-wheel Q2, by which it can be rotated in such a way as to draw the nut Q downward and inward, and thereby elevate the outer end of the parts M M', or, on the 1 other hand, it can be so turned as to let the end move farther out and depress the said parts M IWI. The flexible connection of the part M with the hood K can be provided by an ordinary hinged joint or by means of the device which I have shown. The latter consists of curved guides U, rigidly secured to the rotary base, and rollers V, mounted on stud-shafts, secured to the rings N and P and litted in the said curved guides U. The curvature of the guides corresponds to that of the hood K, and the parts M M can swing vertically at their outer ends under the control of the guides and the rollers at V.4

The longitudinal adjustment for telescopic movement of the section M/ on the section M is effected as folows: The angle guide-bar O eX- tends outward to a point beyond the inner end of the section M. At its outer endit is provided with a bracket O,which at its lower end carries rollers oand at its upper end is connected to the above-mentioned stay-rod R. The upper section Mf is provided with a guide-bar W, which is preferably a light angle-iron I-shaped in cross-sections. This at its inner end carries a bracket V, which latter has a roller w, that lies under the angle-guide O, and rollers w, which lie above the last said guide. It will be seen that the section M' is thus firmly held by means of a truss-frame formed of the parts N, O, and R and at the same time is free lomove out and in because of the antifriction devices which connect together the two guide-irons O and W.

X is a chain-wheel mounted on a shaft which is provided with a crank, this being at the inner end of the section M, and X' is a chain-wheel at the outer end of the guidebar O.

Y is a chain passing around these wheels, and at y it is secured to the bracket WV. W'hen the shaft and wheel at X are turned in one direction, the draft of the chain forces the section M outward, the rollers at 0 and w turning freely and relieving the chain Y from strain, and, vice versa, when the wheel at X is turned in the opposite direction the point vw' is moved rearwardly and the section M is drawn inward.

The hood or delivery-section at Z is adapted to rotate axially on the telescopic section h is a flange on the part M', and z' e" are rollers carried by the section Z and lying inside of and bearing against the ilange or ring. By means of ropes Z, extending down to within reach from the ground, the mouthpiece Z can be rocked to the right or left, as desired.
