PN EU NIATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 569,504, dated October 13, 1896.

Application filed February l5, 1896. Serial ND- 579,438. (No mcdel.)

To @ZZ whom it mtl/y concern.

Be it known that I, FRANK F. LANDis, a citizen of the United States, residing at W'aynesborough, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Pneumatic Strz'tw-Stackers; and I do hereby 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.

This invention relates to pneumatic strawstackers having telescopic discharge-pipes; and it consists in the novel construction and combination of the part-s hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the telescopic discharge pipe, showing it pushed in. Fig. 2 is a plan view ot' the same.

3 is a side view of the operating mechanism at the lower end of the pipe, drawn to a larger scale and showing the parts in the positions they assume when the slidable pipe is extended. Fig. 4 is a plan view of the mechanism shown in Fig.' 3. Figs. 5 and (5 are details.

A is a portion of the casing of a threshingmacliine or separator, and A is the deliverypipe of a centrifugal discharger of approved construction.

B is a flexible junction-pipe of approved construction, revoluble on the upper end of the deliverywpipe A.

C is Lhedischarge-pipe, secured to the npper end of the pipe B, and C' is the slidable section of the discharge-pipe, which slides telescopically over the lower pipe-section.

B' is a circular bracket or turn-table sccured to the top of the'casing A, and h is the cylindrical base of a frame D7 which supports the discharge-pipe. The base b is revolubly supported by the bracket B in any approved manner, as, for instance, by a ball-bearing. The base b has two short uprights or lugs (l secured toit or formed integral with it. These nprights d are arranged one on each side of the base and near its front. Brackets d' are secured to or are formed integral with the rear part of the base b, and are adapted to support the winch E, which may be of any approved construction.

D' are tie-bars coupling together the uprights d and brackets (Z, and forming with the said parts and the base b the said vframe D, which is revoluble upon the turn-table or bracket B.

F are two arms having their lower ends pivoted to the uprights d by the pins f. These arms extend forwardly7 in an upwardly-inclined direction to the axis of the dischargepipe and are parallel to its sides. These arms are preferably formed of pipes for lightness and strength.

F is a yoke or bracket coupling together the upper ends of the arms F and extending in semicircnlar form under the dischargepipe at the upper end of the non-slidable pipesection.

G is a ring mounted on the upper part of the junction-pipe B, or which may be mounted on the lower end portion of the discharge-pipe C. Ilugs el() are secured to the pipe B and prevent the ring` from sliding` longitudinally of the pipe. This ring G is connected to the front end of guide H by the links 42, as will be presently described, and thus forms a support for the lower part ot' the pipe C, and it is provided with two lugs g, which are secured to the arms F.

II is a forked bracket having its lower ends pivoted on the the pins f, and H is a curved rope-guide carried by the bracket H and arranged substantially concentric with the pins f.

The guide H is preferably provided with a bearing 4K1, which is journaled on the central portion of the bracket H. The front end of the guide H supports the ring G by the two curved links 42. The upper ends of these links are pivoted to the guide by the pin 43, and their lower ends are pivoted to the ring G, close above the lugs g, by the pins 44.

The rope-guide I-I is pivotally supported in order that it may adapt itself to all the various positions of the discharge-pipe and in a manner it could not do if it were rigidly connected with it.

The guide or bar Il is provided with ratchetteeth 72, on its under side, the use of which will be more fully explained hereinafter.

The upper end of the slidable pipe-section C' has a ring I secured to it, and a ring I is secured to its lower end. Y p

.I are two guide-sheaves carried by the yoke loi) F at the upper ends of the arms F, and arranged one on each side of the discharge-pipe.

J are two sprocket-wheels or sheaves secured on a shaft j, which is journaled in the upper part of the forked bracket, and j is a crankhandle for revolving the said shaft.

K are liexible connections arranged one on each side of the discharge-pipe. Each flexible connection is fastened at its lower end to the ring I', and thence passes over the guidesheave J to the upper side of the sprocketwheel J around the said sprocket-wheel, and thence through a hole in a lug 1I at the upper part of the ring I to the ring I, and has its upper end secured to the said ring I. For lightness and convenience the lower part 2 of the flexible connection K, which passes over the sheave J, is preferably formed of a cord or wire rope. Its middle portion 3 is formed of a drive-chain, so that it may engage with the teeth of the sprocket-wheel, and its upper portion 4, which is held in a fixed relation to the pipe C and ring I by the lug i', is formed of a rod. A hook 5 connects theV cord 2 to the ,chain 3, and a link 6 conv per side of the discharge-pipe, and the point of the attachment of the upper end ot' the flexible connection with the ring I is a little below the upper side of the discharge-pipe, so that the flexible connection is at an angle to the axis of the discharge-pipe. Then the slidable pipe-section is fully extended, the parts 3 and 4 of the flexible connection are in a substantially straight line, and the upwardlifting force on the ring I due to the anglilarity of the parts 3 and 4 is but little. The lower end ol the flexible connection is attached to the ring I at a point below the bottom of the sheave J. IVhen the slidable pipesection is fully extended, the part 2 of the l'lexible connection below the sheave J is at a considerable angle with the axis of the pipe and exerts considerable lifting force upon the lower end of the pipe. IVhen the slidable pipe-section is pushed in, as shown in Fig. l, the parts 3 and 4 are at an angle to each other and considerable lifting force is exerted on the ring I. The slidable pipe-section is wholly supported bythe tlexible connections, and the parts are so proportioned that the weight of the lower end of the slidable section when pushed in will be balanced by the upward-lifting force of the parts 3 and 4 on the ring I due to their angularity and the tension to which they are subjected by the weight of the pipe. As the slidable pipe-section is extended the tension on the tlexible connection increases, and the angularity between the parts 3 and 4 decreases, so that the pipe slides against a substantially uniform and slight resistance.

The angularily of the lower part 2 of the flexible connections is arranged so as to supplement the action of the part-s 3 and 4 and balance the weight of the lower part of the pipe at all points of its travel as accurately as possible.

The slidable pipe-section is moved in or on the rope-guide and is secured to the barrel 10 of the winch. The winch is preferably provided with a worm 11, secured on a shaft 12 and provided with a wheel 13 or a handle for operating it. The worm gears into a worm-wheel 14, secured on the barrel, and revolves the barrel. The barrel 10 is journaled on the barrel-shaft 15. 16 is a strong spiral spring having one end secured to the shaft Its weight is pracf Its y 15 and the other end secured to the barrel.

The weight of the discharge-pipe is mainly supported by this spring, so that the teeth of the worm and worm-wheel are relieved of much of the weight of the stacker-pipe. The worm-wheel14, being secured to the barrel, is also journaled on the shaft l5, which is stationary.

The discharge-pipe is oscillated upon the turn-table by means of a toothed wheel M, connected to the base b. Motion is imparted to the wheel M by any approved driving mechanism. (Not shown in the drawings.) The wheel M is not secured di rect to the base, but is journaled upon it, and it rests upon the supporting-lugs m.

M is a pawl which is pivoted to the base and engages with any one of a series of notches m in the upper edge of the toothed wheel. the toothed wheel by raising the pawl and may then be turned around by hand. The object of this disengagable connection with the toothed wheel is to simplify the driving mechanism. Supposing the driving mechanism had been oscillating the discharge-pipe through an angle of forty-live degrees on one side of the threshing machine, the pawl can be raised and the discharge-pipe pulled around to the opposite side ot the machine or to any other point of the circle. The pawl can then be dropped into another notch, and the driving mechanism will oscillate the discharge-pipe through the same angle, but in another part of the circle, wit-hout having to be adjusted or changed.

O is a revoluble and extensible deector carried by the slidable section of the discharge-pi pe. This detlector is formed of pivoted segments and a short pipe O, and is provided with a spring o, which operates to hold the segments in their extended position, as shown in Fig. 1. A flexible connection or The base may be disengaged from` IOO IIO

cord P is provided for bending and revolving the deflector. The ends of this cord are secured to one side of Jthe outer segment by'a bracket o.

R R are two sheaves supported at the side of the pipe O'.

S S are two sheaves supported at the top of the slidable pipe C. One portion 'of the cord P passes from the bracket o over the sheaves R and S, and the other portion of the cord passes from the bracket o' over the sheaves R and S.

The deector is bent backward by pulling back both portions of the cord P simultaneously, and is revolved by pulling one or the other portion of the cord, according to the direction in which the delector is desired to revolve.

In order to permit the pipe-section C to be slid in and out without affecting the adjustment of the deflector, take-up devices are used. A yoke 30 is pivoted to the pins f and extends over the flexible junction-pipe under the rope-guide H. Lugs 3l project upwardly from the yoke 30 on each side of the ropeguide. Sheave-blocks 32 are pivoted to the lugs 3l, and are sheaves journaled in the said blocks. The yoke 30 is provided with a pivoted pawl 34, which engages with the ratchet-teeth 71,' on the bar or rope-guide II', so that the yoke 30 moves back and forth with the said rope-guide as controlled by the winch.

A bar 40 is connected to the two flexible conneet-ions K and extends transversely between them. This bar 40 is preferably connected to the hooks 5 by means of pivoted links 41, so that it is free to move to a slight extent in 'a direction crosswise of the discharge-pipe.

Two sheaves 43 are j ournaled on pins 44, carried by the bar 40. The middle portion or loop of the flexible connection P passes' over the sheaves 43, and its ends pass over the sheaves 33, and thence to the sheaves S S and deflector, as hereinbefore described.

The deector is bent backward by pulling back the yoke 30 by hand, and thereby pulling simultaneously on both ends of the cord P. The pawl 34 holds the yoke in position when pulled back, and the spring o draws forward the yoke and extends the segments of the deiiector when the pawl is released from the ratchet-teeth.
