SHIFTABLE STACKER.

SPECIFICATION forming part of Letters Patent No. 399,211, dated March 5, 1889.

Application and April 27, 188s.

o n.7] when?, t fnl/dy Concern:

lle it known that l, VILLIAM S. REEDER, a citizen ot the l'nited States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Shiftable Stackers, ol? which the lfollowing is such a l'ull, clear, and exact description will enable an): one skilled in the art to which it appertains` to make and use the same, reference being had to the accompanying drawings, l'ffn'ming part ot this specification.

)lv invention relates more 'particularly to shil table stackers that are applicable to shuekcorn shellers, tlirashers, and the like.

. The invention consists, primarily, in a universal or flexible shatting of the character described between the stationary power-shaft and the carrier-driving mechanism that revolves with the shiftable stacker.

It consists, also, in certain details of construction, which will now be sett`orth in detail, and the novel features thereof particularly pointed outin the claims making a part hereo'l"` Figure ll is a perspective view ot mystacker applied to a corn-sheller. Fig. 2 is an elevation ot' the mechanism that drives the carrier, slunviug a flexible slotted link-shatting. Fig. 25 is a plan of the latter, the upper halt ot' the same being removed; and Fig. Je is an isometric projection of a portion of the flexible slotted link-shaftiug.

The same ligures of reference indicate the same parts throughout.

l is the rotary shaft, that is driven by a pulley, i), rotated by a belt which has power applied to it by any suitable rotary part of a machine.

25 is the shil'table stacker, which is supported by offsets i Lt and cord 5, attached to the top of the machine. .The oisets liare supported by pillars l C, which are sustained by cross-pieces T S, that bear upon a circular table, 9, together forming a turn-table, which is supported upon the front part of the machine by a llange, l0, that carries a bearing i'or the driving-shaftl. The lower part ot the offsets l JL are fashioned into boxes, iu which shaft i7, to be hereinafter described, is journaled. These boxes are in turn journaled in the upper part oit the pillars C so that the stacker can be raised or lowered. The

Serial No. 272x057. (No niedeld pillars (3 l; are screw-threaded at their lower ends, and are screwed to the cross-piece T by nuts on each side of the same, whereb7 they can be raised or lowered The tahle fl provided with a rim, ll, upon which the crosspieces bear. The cross-pieces 7 S arepivoled at the center ol the table which has also a rim7 1Q, near its center for the cross-pieces T S to bear upon near the pivot.

lil 1S are the ears by which the table and flange l() are secured to the machine. From the shaft l. extends a universal slotted linkshat'ting, l-l, to a sprocket-wheel, l5, which is journaled in a downward extension, lG, ot the cross-piece 7.

Through the boxes ot' the oitsets i l passes a shaft, l?, carrying a sprocket-wheel, 1S, which drives the carrier if', that removes the cobs or straw from the stacker, said carrier being' made up el? a sprocket-chain having cross-pieces attached thereto, as is usual. Upon the end of the shaft i?, just over the sprocket-wheel l5, is another sprocket-wheel, 20. "letween the sprocket-wheel l5 and Jthe. sprocket-wheel Q0 is a sprocket-chain, 2l. .Vhen the shaft l is rotated, vit drives the sprocketfwheel l5 hy means ot the liexible slotted link-eoni'iection, which sprocket-wheel 15 actuates the slnocket-wheel 2o through the instrumentality of the sprocket-chain 2l, and thus drives the sprocket-wheel i8, which in turn drives the carrier lf) to remove the cobs and shucks. Should the stacker be revolved by hand to a second position, this will revolve the cross-pieces 7 S and the driving mechanism about the pivot as a center, so that some means has to be devised to give the. shafting between the sprocket-wheel l5 and the stational-y shafting il llexibility, and this is the principal feature oi` my invention.

My flexible shaftingis made up, preferably, of two series of links. 22 213, and il, the link 22 being provided with pil engaging slots in the link 223, and the link '2lbeing provided with slots which are adapted. to receive the pins of a second pin-link. (See Fig. i.) The link 24 and the link 23 are in fact one link, as they are made in one piece. rThe slot and pins allow great play and `liexihilitT of this link-shafting, so that the stacker may he moved through a quadrant without 'interfering with the operation ot the driving mechanism. It will be seen, therefore, that the stacker may be swung' round at any angle up to ninety degrees without interfering with the operation of the mechanism in the slightest. Should the sprocket-chain 2l become slack, the pillars 6 (i can be raised to take up the slack, or lowered to relieve the strain upon the chain, as the case may be.

Other forms of universal shafting may be used without departing from the spirit of my invention.

25 and 2G are the ordinary hinged side boards of the stacker.

Having .now fully set forth my invention and described its operation, what I desire to claim and secure by Letters Patent of the United States as my invention isl. The combination, with a shiftable stacker, of a driving mechanism for the carrier of said stacker rigidly secured to said stacker and revolving therewith, a stationary power-shaft, and a iiexible slotted shafting between said stationary power-shaft and said driving mechanism, consisting` of links 22, having pins projecting therefrom at right angles to each other, andatwo-partlink made of slotted links 23 and 24, joined rigidly together at right angles to each other and engaging the pins aforesaid.

2. A stacker having adjustable pillars, as G G, between the carrier-driving shaft and the platform which carries the mechanism for actuating said shaft, for the purpose set forth.

The combination, with a shiftable stacker, of offsets, as 4 4, supporting said stacker and terminating in journal-boxes, pillars, as G 6, in which said boxes have bearings, whereby the stacker can be swung up or down, a carrier for said stacker, a shaft, as 17, journaled in said boxes and carrying gearing for said carrier, a turn-table to which said pillars are adjustably secured, a gearwheel, as l5, carried by said turn-table, a stationary power-shaft, as l, and a iiexible connection between the latter two.

In testimony whereof I have hereunto set my hand, this 21st day of April, 1888, in the presence of the two subscribing witnesses.

XVM. S. REEDER.
