HAnvEs'rfINe MACHINE.

Application filed January 16, 1922, serini No. 529,778, and in Great Britain January` 20,'11921.

This invention relates to harvesting ma chines of the kind in which mechanism lis provided whereby groups ot sheaves of grain or the like, after being formed in the seinblance of shocks `or stocks, are deposited on the ground in an upright position; and my invention is essentially characterized by the use or provision, as the means for conveying the groups of sheaves, of aring, or ring like structure, Jformed in two or more parts, and means whereby vthe component parts lof said ring` may be .closed and opened andv advanced and retracted in such mannery that it (the ring) will grip and hold .a group of sheaves atteibeing formed in the semblance of a shock ot' stook near the topsthereof, carry :same to the desired point yof discharge Vor delivery, deposit it as a shock or .stook upon the ground, and then open to release it so that it will stand firmly vand in a stable condition on the ground'.

Said ring may be constructed invarious ways, as for instance, it may be composed of two substantially semi-circular components each of which in turn may be built up ot' a number of hinged or pivoted segments;

and the actuation of the, ring may be effected 1n any convenient man-ner, but I preter that said ring with its carriers, et cetera, shall be mounted upon a suitable .p.latf orm., i'rame,

or the like, which is so controlled that fat the time of the deposit of a I'shock or .st-ook upon the Aground said frame is travelling rearwardly at -or about the` same speed as: the

machine is travelling forwardly, so that the shock or stook is deposited upon thev .ground as it' from a stationary machine or carrier.

It necessary or desirable in 'orderl to. ensure the stationary deposit `ot axshock .or ,st-ook upon the ground, it may be arranged that the holding ring shall remain atrest for a period which will Aenable it to. open and clear itself of the shock or stook before being moved forwardly again Vto receive Ifurther supply. A

Said ring components may be of anysuitable shape or .conifiguratiom so thatv when the parts are assembled the ring may.,b.e round, rectangular7 .or elliptical; andv theinter-i-or faces thereoic .may f be roughened, toothed, serrated, or provided with prongs,

in order to enhance their gripping effectA upon the shock or stook.

I Will further ydescribe my inventionwith K. Tn said drawings parts: l Y f .Anfup-per part consisting .of fa hori- 100 the aid of the accompanyingsheetsor1 diagi'ammatic dravving-s, which illustrate, by way kot example only', one mode whereby the same may 'be carried into eiect.

.Fig 4l isa transverse section taken on line showing the binder. 'y p Fig.,5 is any enlarged detail of a vporti-on of thel apparatus. Y i

The apparatus as shown, is an attachment or adyunct to ja binder or self-binder reaper.

`There vis provided la steel main frame X, rectangular in shape, which' fra-me is carried at its outer side on a pair of wheels, and its inner side is supported by the frame o the binder and wheels, it necessary; power may be transmitted to it for the `ope-ration of` its parts from the binder. This; trame carries and supports (a) a receptacle 39 and 37 for receiving the .sheaves from the binder; (Z2) a stookforming or moulding mechanism 30 and 32 whereto the sheaves are'carriedlfrom fthe receiver 39 and 37 and ring.

As .the Vbinder-andstookingmachine are l vmoving torward,say at the rate of threeand 90 a half to four miles per ho-ur, Ithe stooking ring must move backward at the same speed .so that the stooky may. be deposited on the ground .asif' from astationary machine. To eliect thisoperation mechanism is pro- 95 vided vinthe ,form of a glidingframe 3,13, l5, which operates/ insidewsaid.main fname.

This gliding.framel censistsot two chief zontal bai` 3 rigidly attached to two'flongitudinal ba'rfs'l .which ride on vtwo wheels 1S .each on the upper part )of ti-hemain trame 2l, 22, Aand which gliding `traine ,niovesdirectly backward and forward within a range 105 of say eight teetfpowerjbeing transmitted to it and its movements timed Aloy`.s.uitable mechanism located in the mainframe)- ;and

two vertical pillars or pivots 13 passing through the horizontal bar 3 and adapted to control the respective halves vof the stooking ring 1.

(2) The stocking ring 1 and the mechanisnr-Q,i2,fwhich"carries and controls each rin component.

aid main traine should admit of being raisedaiidlowered in relat-ion to `the ground according'as the grainito be outnis long or short, and it, of course, must be open below at therear end to permit ot' the st-ook to pass out.A

` Fig. 1"'of the drawings shows an upper track 21 and 22 which carries the upper part of the gliding 'fraine,aiid` a lower track 19 `and 2O which carries supports 9- et cetera of the stoolingring by ineansotL` a flange wheel r17. Said `lower track has. (a) a horizontal spart which carriesthe stookingring directly backward until the stool( has been pulled clear of 'the inoulding or stook-torining cones'SO, 32. and has swung downward iii a vertical position;` and (b), a sloping for in- `clinedpart which perinits the stocking ring y and stook to drop directly to the ground,

Mid at the saine time to be carried backward aty the `saine speed as y the whole machine travels 'forwardLso that fthe stook` when dropped will be practically'standing still as regards horizontal motion inrelation `to the' ground.` i l i "The lower track is jointed-"at 23`i1ninediatelyinfrontot' the bend, and the rear end is so arranged that the rear part of the Vtrack 19, 2Q may inove up Vand down fron] "he `joint"23 and gap 24,` to permit ofvvaria- Vtionsiri" lengthsof sheaves. v

"F'gl Bof the drawing illustratesthe gliding fraine, andl, showingthe stook` ing ring 1 ina vertical position and closed, a's it will be `when it has grasped the stoolr and is withdrawing it froin` the stookfforni- " ing cones 30, 32. i

It also shows across section `ot vertical pivots l13 which are located in alooxing 9 i fbelow the level of theci'oss bar Sol gliding . traine 3, 13, 15. i i i. Fig. 2 `of vthe drawing shows in" plan the gliding traine, 3, 13, 15 and vertical pivots 13 fulllines and Inoving forwardly to receive astook and indotted linesldepositing a stool: upon the ground, and showing the structure of the *frame and its carrying wheels 18. andthe topvieti7 of the vertical pivots 13 which are.part of the gliding `frame `3. 13,1

15 `and are `atfthis partroiind` so that they Acanfrotate each'around its vertical axis.

"The rotation offeach pivot 13`is coordi-` hated inrelation to the other` by means of fi lever 5 which, in turn'.` is attached to the lever 5 of the pivot13 on `the opposite side by means of across'bar12. r i

" VReferring again to Figs. 1 to 4 Y The stocking ring 1 is provided with swings to prongs 27a more orless radially arranged; said stocking ring is inade up ot two separate and distinct halves, each otwhicli con- Sists of a central part 2G whei'eto is solidly attached the horizont-al pivot 2V and terminal `segments 27 at eacliend of the central part 26, such segments being suitably pivoted to -open andi close in the plane oit the stocking ring and controlled by rods 10 working on lever 28 on eachseginent. As each halt ot' the stooking ring swings forward or baclr ward (see Figs. 1 and 2) tlfiroughthe rota tion of the vert-ical pivots 13 they separate', and also each distal segment 2T is pulled open by the rods 10`acting onV the segment y .tlievertical plane when grasping its load `and in a horizontal pla-ne when releasing it.

The 4rotation oi: the stooliiig ring, troni its normally vertical position to a horizontal po-A sition, is `effected by the stock but it (the ring) returns to its original position dueto one side of said ring being heavier thantlie fother.

3 is a heavy cross bar designed to inaiiitain the rigidity ol the gliding 'traine 3, 13.y 15; it is attached to the loiigitiiiilinal bar 15, and passing through it are tlievei'tical pivf OtS 13. r r i y `6 isv aV ring which passes ai'oiindeach stook- 1ing ring carrier9 and has `attached to it the wheel 17, which carries said stoolringring carrier 9, stooling `ring 1 and its loadV oi sheaves. A stocking ringcarrier 9 inay ro- 'tate insideits ring Gfso thatytlie `wheel 1T remains in a straight line on its track.`

16 is acontrol ro'dfthe downtui'ned outer end whereof rides infan approifiriately cufi'ved 1groove 16 foriiied 'in `a guide plate 1Gb se- "cureditoring 6"; the ends of said guideplate 16h abut against the adjacent vcrtiralbars 14 and are free to slide up anddownon sQid `bars; thus the guidefplate is prevented `troni turning. The inner end oit said rod 16 is grooved to fit over a ridgeriiiining around jthe control cuil" 8 and pulls `said culi outward and through it" the control rods 1 (l1oiitward,"'to open the distal" segments QTwhen the stocking ring 1 swings.backward oil forward to open. As the stocking ring the centre, the reverse action tal-ies place.

' Said control cuff 8V encircles `itsliorizontal pivot 2 and is free to slide longitudinally on saine7 but 'cannot rot-ate around it. It controlled by a pin on the pivot 2 sliding in the groove in the cuff 8. To said (guitare :lit-

,tachedthe' control rods 410, so that said lll() ycontrol r-ods 16 the distal cu 8 is moved'inwards or out-wards by the segments 27 will be closed or opened. y

A `stooflring rin-g carrier9 possesses two 'chief partez-(64) -a vertical part square inside 'wh-'ere it surrounds the square vertical pivots 13; this carrier 9 is a smooth bore hoxin'g tree to slide up and l down on the pivot 13,-but is controlled in its rotation, however, by said pivot 13; it is tree to rotate inside the ring 6 which carries it and regulates its height, the ring 6 being carried by the wheels 17 g and a horizontal part carrying the horizontal pivot 2 of its stooking ring; this'mnst allow the horizontal pivot 2 to rotate'on its long axis through an ,angle of 900. As it is essential that the vertical Ipart of thecarrier 9 shall slide easily up and down on the pivot 13, and as itwill tend toA be twisted out ot the line of the pivot 13 hy the weigl-it oliv the loa-d in the stooking ring 1, it may be necessary to provide small wheels or rollersy at the upper and lower ents of `this `vertical part to run on the `pivot 13 te prevent l'bindingor gripping.

Said vertical pivots 13 control the opening 'and closing of the st-ooliing `ring 1 and also carry it hackward and 'forward at the same time allowing it to fall and rise according to vthe bend of the lower track 19 and 20. At vtheir upper ends they pa-ss tl-ii'ough the liar 3 of the` gliding frame 3, 13, 15, the pasiages whereof are round so that the pivots 13 may rotate on their long axes.

yThere are provided upright bars 14 which are 'parallel with the ,vertical pivots 13-a pair on each side; `these are attached above to the longitudinal hars 1,5, and'inay be connected together' at their lower ends.; they prevent A'the guide plate 1Gb. 'from turning and add rigidity to the vertical pivot 13.

Said control rod 16 lies in agroove or slot yon the horizontal part ot' .thestooking'riug carrier '9 and pulls the cuil 3 to open the distal segments 27. 1

The members 19 and 20 ofthe lower track are suitably attachedvtogether so as not to interfere with the passage of the wheels.

.Tracks 21 and 22 .are similar to tracks 19 and 20, hut these are not jointed or broken, and run straight from front end to rear.

Figs. 1 and/2 show the approximate posi tions andrelationship of the binder or seltloinding reaper and stooking apparatus: They also show the stooking ring 1 open and moving forward to grasp the load oft sheaves or stook, and stooking ring closers. l

` vEach stooking-i'ing closer comprises an arm 25a .attach-ed to the horizontal pivotv 2, 'and a i'lat piece oft wood ..25). As the stookn ing' ring 1 is carried forward, open as shown, the flat pieces 25b abiit against thetop oit the stool: heldin .the inoulder 30, `31, 32, and close the two halves oi" the ring 1.I y Y Fig. 2 shows a plan view of Vthe she-af :a binder of any known kind. The sheaves cannot he carried into the stool; moul'der 30,'

Said cone -30 is provided 'with six lspacer plates or -spolzes 31 which divide its sloping surface into six areas, one for :each -s'h-eat. In these areas the sheavesare held in proper arrangement andare so spaced :as to form a well shaped stool or shook. The

As .soon as the "loader iin 43 ceases topi-ess on fthe sheat, Athe inner cone 30 ceases to revolve and will remain stationary due to the pressure'oitthe sheal` against fixed rods 32. As the next sheat' is carried up this process is repeat Said plates 31 are attached to th'e inner4 cone 30, as shown. They are `'curved at the front end, i. e. towards the base of the cone 30 so that as the stock is gripped by the Ystooking ring 1 and pulled -out ot .the moulder 30,31, 32, the sheaves `will ride upon :the top ot the spacers and thus will not jam 'orL Y' wedge in between two spacers. p

3'2'are outside cone rods, 'two in number. rI hey will, of necessity, bev-ery strong as they will have to hold siX sheaves in place around the inside cone 30; they are lin 'two seg-ments or parts so that they Ican swing ` Inoulder 30, 31, 32. stook being. pulled out and clear `ot the .open to allowthe Vstock tobe pulled out by the stocking ring l. i l.

Said hinged parts 32CL o'l conerods 32 are so jointed that they can swing inward towards the innerI conc 3() to allow the `sheaves to pass into the lnoulder 30, 31, 32, but `will not swing outward apart trom the segments to which they are attached. The

opening of these outside cone reds 32, 32 lmust take place when the stock `is gripped by the stocking ring and pulled out ot the Immediately on 4the `moulder these rods 32, 32 must close firmly and be ready to` receive another,` load of sheaves. Said rods open and close atthe hinges 47, 47; they are carried by the coned 331, 33b are the shea'f carriers; these are ftwo in number and may be chains ruiming on sprocket wheels. Each carrier is vprovided with iins45 which project above the :level oftthe rods of said sheat holder 39,

so as to catch the sheaves and carry them on to` the loader 42. Said carriers will run `continuously while the machine is in action.

34 is a shelil oit rods which direct the sheaves as they are thrown trom the binding `table of the binder onto the shca'f holder 39;

35 are several rods jointed at their top end Aso that they can swing'A away from the binder but can only come back to a vertical position where they meet a pin or the like. They are designed to allow the sheaves to be `thrown into the holder 39, but prevent .any1 from falling back and obstructing the space marked Z along whichthe vertical pivot 13 and uprights 14`travcl when the stocking ring 1 is grasping its load.

36 is a portcullis ot rods. The function of these rods is to arrest any sheaf that is thrown from the binder while the vvertical pivot 13 and uprights 14 are forward in the `space Z.; their downward and upward movement may be brought about `by any suitable known niechanism t not shown) on the forward and rearward travel respectively otuprights 14.

33, 38a, 33" is one of a pair of sheaf arresters. It consists of a `normally vertical part 38FL an upwardly directed outer part 381 and an intermediate depressed part 38; Said arrester is pivotally supported vatl 33C. They are designed to ensure that only one .sheaf When at a time may be on the loader 42.

`said loader 42 is empty the vertical part 38a falls under the influence of gravity, below thelevel of the rods ot `the sheaf holder 39.

`As a sheaf falls on the carrier 33 and is carriedon tothe lower end of the loader 42 Vin a closed position.

itdepresses 38b and raisesf38f. `NowVno more sheaves may beV carried on to the loader 42 (which has stopped while the sheaves are beingl grasped and pulled out of the inoulder 30, 31, 32, by the stooking ring `1) until the loader 42 starts running again.`

rllhe sheaves are thrown from the binder onto the sheaf-holder 39 at varying speeds according' to the width of the swathecut, the speed at which the binderis travelling,

`and the thickness of'the standing grain. `The sheaves cannotrbecarried 1n a continuous stream into the moulder 30, 31, 32as there mus-,t bea stop while the stock is being grasped by ring `1 and pulledout Hence, the provision of holder 39 .to receive the two or three` sheaves thrown out during such delay. Said sheaf holder39 co1nprises,a s shown, a vertical part to keep` thesheaves from fallingl into the spaceZ, a horizontal part, and a sloping partthe latter directing the sheaves into the nioulder 30, 31,32.

Said wall 40 isa sheet Vof lmetal against which the sheaves vabut whilst beingthrown from the binder, and carried intoandheld in the inoulder 30, 31, 32.4. i. M

Said fins 43 andl 45 ogtjthe loader and carrier, respectively,may beinade of loops ot' metal; as the sheaves come upagainst 38aL and meet strong resistance the lin 45Qwill slip under the sheai'andallowthe carriers 33 to continue running. j j

Referring now toFig. 5.0i the drawings, secured on the bar 3 is a plate piece-.G1 having aninclined upper surface 61a anda posterior vertical surface `61"; and ahflat blade of spring steel 67 hinged at 68.1,

Secured tothe posterior part of the main j frame is a rigid bar 65 the front edge where- ,of'is inclined and on its upper surface there is provideda projection 66. Assuming the parts are in the position shown in tFigs. 1 .and 2 and the gliding frame `3, 13, `15, is advanced in the direction ot the arrow, when the stooking closers25, 25:l Ineetthe vstool; of sheavesA the ring components are closed (as shown in Fig. 3) `to grasp the stook. j

' As the bar 3 ofthe gliding framemoves forward, arm 4, which isa fiat pieceof spring steel and secured ,toV the adjacent pivot 13, by reason of its spring construetion, rides up the inclined iplanel 61, and

enters the space between the vertical Vportion 61b and blade 67;

thus ringr 1 is locked The gliding frame is -now released from i suitable carrying mechanism infany convenient way.

As sheaves vary `'in length and must .be grasped at a suitable distance from the head-s, appropriate Vmeans may be provided The cones 32 now open to allow the sheaves.

to be withdrawn, moves backward and reengages with the gliding frame, and withdraws the .sheaves from t-he cone 32; when withdrawn the weight of sheaves causes the ring to turn to a horizontal position.

The stook now travels rearwardly of the machine and drops solidly on to the ground.

In the continued rearward or retractive movement of the gliding frame 3, 13, l5 (which movement is equal to the forward movement of the whole machine) the lever 4 meets bar 65 lwhich flexes blade 67 laterally out of the way of lever 4, but the projection 66 engages lever 4.

As soon as bar has flexed blade 67 out of the way it passes under lever 4 and the extension 49 of bar 4 meets the interceptor 63 secured to the main frame with the result that the ring l is opened somewhat.

Now the gliding frame having reached the posterior limit of its travel begins immediately to move forward, but lever 4 is for a time retarded through the engagement of a catch portion 66 with it, the result being that the ring 1 is completely opened, swings away from the stook and moves backward at a speed equal to the forward movement of the machine.

In the continued forward movement of the gliding frame, lever 4 automatically disengages from projection 66, the extension 49 of lever 4 engages the anterior interceptor-62 of the main frame and ring l is swung forward. In the forward movement of lever 4 it rides over blade 67. Said interceptor 62 is ofa spring form so shaped thatextension 49 of lever 4 in the rearward movement of the gliding frame will pass it.
