PNEUMATIC STACKER.

SPEGITEIGA'IION forming part of Letters Patent No. 633,561, dated September 26, 1899. Application filed December 30, 1,897. Renewed November 18, 1898. Serial No. 696,827. (No model.)

To all whom it 7771(01/00721667f7b.

Be it known that I, J OHN B. B RTHQLOM W, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have in vented certainnew 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 draw ings, and to the letters .of reference marked thereon, which form a part of this specification.

Figure 1 is a sideelevation of a pneumatic stacking mechanism embodying my impro vements. Fig. 2 is atop plan view of the same. Fig. 3 is a detail View. Fig. tie a side elevation showing a slightly-modified construction. Fig. 5 is a top plan View of the parts shown in Fig. i. Fig. 6 is a side elevation of the stacker trunk or duct, constructed as shown in Fig. 1, on an enlarged scale. Fig. 7 is a transverse sectional view taken through the duct on the line 7 f Fig. 1 and showing the support for the stacker-tube in rear elevation.

In the drawings, A designates the rear end of a threshing-machine, which may be of several styles.

A designates a vertical tube or duct by which strawand chaff from the interior of the thresher are conducted upwardly to the dislation to the body of the trunk, I do not believe it necessary to either illustrate or. describe in detail the construction or manner of mountingand supporting the trunk. lt is sufficient to say that 0 indicates a peripherally-toothedriug or base, upon which the stacker-tube is mounted, and c designates a pinion for rotating said ring and tube about a vertical axis. Suitable mechanism is provided for automatically reversing the direction of revolution of the pinion c at predetermined intervals, so that the stacker-tube will be vibrated through thearc of the circle concentric wilh the axis of the ring 0, and at T I have indicated one form of mechanism for elongating the discharge-trunk to correspond to the increase in the height of the stack.

With machines heretofore devised for utilizing a blast of air for stacking straw means have been providedfor depositing the straw at various points in aline extending transversely of the stack, (being the line of move ment of the outer end of the discharge trunk or tubeg) but the result has been that the straw was deposited in a relatively narrow ridge-like form, and it was necessary to manually distribute the straw to points beyond such ridge to provide a proper stack.

The object of the present invention is to provide means by which the straw will be automatically discharged uniformly over the entire top of the stack.

As shownin the drawings, the hood or defiector at the outer end of the stacker-trunk consists of three telescoping sections D D D The inner of these sections D is rigidly secured to the tube-section B while the other two sections D D are pivotally connected together and to said inner section at d. Short sections of chain or cable d are provided for limiting the outward or downward movement of the sections D D relatively to each other and to the section D. When the lower or outer section 1) of the deflector is in the position indicated in full lines in Fig. 1, for example, it will be seen that such section acts to limit the outward motion of the straw and to cause the same to be deposited at tube: To effect this automatic vertical movement of the defiector,I provide the following devices: 7

Referring to that embodiment of my inven- I tion illustrated in Figs. 1, 2,and 6, E designates a lever-arm which is riveted or otherwise rigidly secured to one of the side walls of the deflector-section D and extends on opposite sides of the fulcrum or pivot d. At its upper end this lever-arm carries a guide roller or sheave e, about which extends a rope or cable F. This rope or cable F extends around suitable guide rollers or sheaves G G, mounted, respectively, on the section B of the stacker-- trunk and on the arm or standard h, extending upwardly from the bracing and supporting arm H, and has one end connected to one arm of a bell-crank le verK and its other end connected to a hook-like projection on the inclined brace-arm H. The bell-crank lever K is fulcrumed at it upon a bracket secured to one of the framing-bars L of the trunk, and the arm of said lever is connected by alink or rod M with a sprocket N. The latter, which is mounted on a suitable shaft journaled in the stacker-trunk-supporting frame, is connected by a sprocketchain N with another sprocket, N The latter is mounted upon a horizontal shaft n, provided also with .a bevel-pinion n, Which meshes with a bevelgear 07?, carried by a vertical shaft 71?. This shaft 'n is provided at its lower end with a pinion n, which meshes with the teeth of a segmental rack N rigidly and stationarily secured in position upon the framework on the thresher A and extending concentric with the ring or base 0, by which the stacker-trunk is horizontally vibrated.

From the above description it will be seen that as the ring or base 0 is revolved the pinion n will be carried around the rack N and the engagement between the teeth of said pinion and rack will rotate the sprockets N N and rock the lever K about its fulcrum it. As the lower end of the rope or cable F is fixed and held stationary, it is seen that as the upper end of the lever K moves rearwardly in the direction indicated by the arrow the deflector-section D will be rocked upwardly and rearwardly about its pivot at d. A coiled spring D isinterposed between the rear end of the lever-arm E and a'lngb on the stacker-tube, and this .spring acts to return the'deflector-section D to its original position as the rotation of the sprocket N causes the upper end of the lever K to move forward. The lower end of the cord or cable F is preferably provided with a ringf, adapted to engage with either of the series of hooklike projections h on the brace-arm H, and this lower end of such cable is within easy reach of an operator standing on the ground adjacent to the rear end of the machine A. By drawing the rope or cable F the operator may vary the i-nitialposition of the deflectorsection D with relation to the stacker-tube and secure the same in such position by attaching the ringfto the proper'hook h? By connecting the automatically-acting power devices, which actuate the deflector relatively to the duct, to the deflector by means of a cord or chain arranged substan tially as set forththat is to say, a cord or equivalent which is secured at one point to the automatic deflector-moving devices and secured at another point to a relatively stationary holder or support, as to the parts at hI provide for automatically moving the deflector relatively to the duct by the power devices and also provide for moving it by hand independently of the power devices. The operator, should he at any time see the stack taking an undesirable shape, can by hand open the deflector by drawing upon the cord, even though the automatically-acting mechanism is at work.

It is usual to provide stacker mechanisms of this class with means for u'nclutching or throwing out of action the devices which effect the horizontal movements of the duct. This is done to-enable the operator to stop the duct temporarily and deliver to some one part of the stack a larger quantity of straw. WVhen this is done with the mechanism herein shown, I can still adjust the deflector by hand to deliver the straw at the desired points, and by so arranging the parts that the cord shall have one of its ends or fixed parts ac cessible to one standing on the ground in the way illustrated every desired adjustment of the parts of the duct, as the movements of the hood or deflector and the adjustment of the telescoping parts, can be accomplished from the ground and without requiring any climbing on the machine.

By having that part of the cord which is secured to the relatively stationary holder adjustable in the way illustratedthat is to say, constructing and arranging the parts so that more or less of the cord can be taken up or let out-the deflector can be governed as to the part which it shall follow of its total possible path. Thus if it be desired to have it move only in the lower part of its possible path the cord is lengthened or let out, but if it is desired to have it move only in the upper part of its path the cord will be shortened or taken in at the fastener 1-1.. Thus provision is madefor directing the straw at times mainly inward or toward the machine and then for directing it during a desired period mainly in a direction away from the machine.

Again, by having the other fastened part of the cord arranged to be adj usted along the vibrating lever K the throw of the deflector or the length of the are through which it moves can be adjusted irrespective of the part of the path in which it may be held by theother part of thecord. Thus at the bottom portion of the stack it is preferable to have the power-transmitting cord secured farther away from the axis of the lever K, so that the vibrations of the latter will carry the deflector over a relatively long path and deliver the straw on a relatively wide base;

but as the top of the stack is approached it can be narrowed or tapered by bringing the end of the cord nearer to the axis, and then the movement of the deflector will be in shorter paths and the straw will be delivered over a reduced area, and by having both these adjustments-namely, that which is attainable by having the cord adjustablyattachable to the lever at differentdistances from the axis and that whichis attainable by increasing or decreasing the total length of the cord-I can provide for every desired result as to the delivery of the straw supplemental to what are provided for by having the duct itself extensible and vertically and horizontally adjustable, and, still further, it will be seen that I not only have combined with the duct and the deflector movably mounted thereon the above-described means for efiecting the movements of the deflector by hand and at will and also means for moving the said deflector by power devices which do not require hand actuation, but also have arranged the devices which transmit motion to the deflector in such way that the duct can be lengthened or shortened without interference with or from such motion-transmitter. As shown, this is accomplished by securing the cord at one point to the power devices and at another point to a relatively stationary holder and between said points connecting it to the deflector byacord-guide which permits the guide to move therethrough while maintaining engagement, and I supplement these parts with a take-up for the cord, which supplies idle cord when necessaryto permit extending the duct and takes up such idle cord when the ductis shortened.

In another respect the present construction is a particularly advantageous one for embodying my in vention-namely, in this, that the power devices which actuate the deflector are situated at the axis around which the duct is vertically adjusted. 'When so situated, the distances between the driving and the driven parts can be maintained substantially uniform irrespective of the horizontal or vertical position of the duct. Of course in this respect there can be variation and the power devices can be situated otherwise; but for some reasons I prefer that shown and here referred to.

In Figs. '1 and 5 I have illustrated a slightlymoditied construction. In this construction 0 designates a cylindrical or tubular rockshaft mounted in bearings 0 0 on the second duct-section B, and O designates a rockshaft which is mounted in bearings 0 0 on the outer section 13 the inner end of this shaft 0 fitting within the shaft 0, so as to move longitudinally thereof, but connected thereto to vibrate about its longitudinal axis therewith. At its outer end the shaft 0 is provided with a crank-arm 0 to the free end of which is connected a short chain-section 0 the lower end of which may be engaged with either of a series of apertures d, formed in a bar 61 secured to the deflector-section D To the rock-shaft 0, near the inner end thereof, is connected a crank-arm 0 the free end of which is connected to one end of a link P, the other end of which is connected to the sprocket N. It will be seen that as the sprocket N is rotated in the manner hereinbefore de scribed the link P and crank O will'cause the compound rockshaft 0 O to vibrate about its longitudinal axis, and the upward movement of the crank O at the outer end of said shaft will act to raise the deflectorsection D As the revolution of the sprocket N brings the parts P O 0 into their origi= nal positions the weight of the section D will cause it to move downwardly about its pivot at d.

Any suitable power devices may be provided for driving the pinion c. In the drawings I have illustrated, more or less conventionally, a train of gearing connecting said pinion with a band-wheel U, mounted on the thresher A.

At V is indicated the casing of the fan or ejector, by which the straw-moving blast of air is created, said casing communicating with the uptake-duct A.

From the above description and the drawings it will be seen that as the stacker tube or trunk is rotated about the vertical axis of the cylindrical base 0 the deflector at the outer end of such duct will be automatically vibrated about its pivot and thestraw escaping from the section B will be guided to points relatively nearer or farther from the outer end of the duct on a line transverse to that of the horizontal movement of such end, so that the straw will be uniformly distributed over the entire top of the stack.

However, I do not herein claim, the specific matters incident to the construction shown in Figs. 4 and 5, having made these the subject of claims in another application filed by me-to wit, Serial No. 696,875, filed November 26, 189S-but herein call attention to the construction illustrated in said figures and last above described, inasmuch as it shows the fact that many features of my invention can be readily embodied in numerous forms of mechanism.
