SPECIFICATION forming part of Letters Patent No. 526,602, dated September 25, 1894. Application filed February 21, 18937. Serial No. 463,200. (No model.)

VTo all whom it may concern:

Be it known that I, EZRA E. WITTER, actizen of the United States, residing at Milford Centre, in the county of Union and State of Ohio, have invented certain new and useful Improvements in Oorn-Harvesters, of which the following is a specification.

The improvements forming a part of the present invention bear an intimate relation to the general form and construction of the corn-harvesters heretofore patented by me, and numbered 458,088 and 470,609, and I consider them valuable additions thereto.

The most important change over my former patents is that instead of tilting the main frame it is carried level all the time, but to vreach the downcorn more effectually I provide supplemental movable gathering points. rlhe present invention further consists in mechanism for changing the speed of the carrier-chains which elevate the down corn. This is essential becauseas the corn lies away from the machine sometimes, it needs to be moved faster than when it lies athwart or toward the machine.

My invention further consists in the employmcntV of a peculiar construction of com presser on the shock-forming frame, whereby the shock is compressed at top so that it can be bound more tightly.

My invention further consists in an improved form of partition to the revolvingtable, it being so constructed that it will not tear the binding off the shock when it drops through the skeleton frame.

Another improvement consists in doing away with the longand cumbersome pawls which move the revolvingtable, by the provision of a mutilated gear which does not turn said table until the shock is tied, and then drives it until the vertical partition reaches the line of draft.

My invention also consists in other improvements and parts, all of which will be hereinafter described and then particularly speciiiedin the claims.

In the accompanying drawingsz-Figure l is a plan view of my improved corn-harvester. Fig. 2 is a partial plan View thereof, parts being shown in section. Fig. 3 is a front elevation, part of the shock-forming frame being broken away. Fig. 4 is a side elevation of the main frame and part of the shock-forming frame. Fig. 5 is a detail view of part of the front portion ofthe machine. Fig. Gis a detail View of a movable gathering point, and devices for operating it. Fig. 7 is a sectional View of a portion of the shock-forming frame showing the vertical partition in elevation. Figs. 8, 9, l0 and 1l are detail views of parts of the revolving-table, showing the catches for supporting the leaves. Fig. I2 is a plan view of the shockforming frame partly broken away. Figs. 13 and 14 are views showing the mechanism for operating the knotter (not shown) the needle and the revolving-table. Fig. 15 is a detail view showing the catches for the gate which is in the rear of the shock-forming frame and how it is they are actuated.

The framework of the entire harvester is substantially the same as that of the patented machines, referred to, and will not require a detailed description.

Referring to Figs. 1, 2, 3 and 4,it will be seen that the main frame A is supported on the usual master or main driving wheel A', and the grain-wheel A2. The shock-forming frame B, which includes the binding mecl1- anism and the mechanism for discharging the shock, is linked to the main-frame, and is supported on the caster-wheel AS at the rear.

In my last patent, numbered 470,609, I have shown a construction whereby the mainframe is supported on the master-wheel A and the grain-wheel A2 so that it may be adjusted vertically. In the present invention I have shown a somewhat similar arrangement, but in addition have provided means for adjusting the master-wheel frame horizontally or laterally with respect to the mainframe. These parts will now be described.

The rear beam a of the mainframe has a forwardly extending beam a at the left end, (when looking to the rear) forming one side of the mouth or entrance G, and from which projects a lateral beam (itin front of themas` ter wheel. From beam a2 projects a Ashort forward beam a3, between which latter and the beam a the draft-tongue a4 is pivoted on a rod a5, connecting beams a and a3. Extending np from the rear beam d and the front beam o? of the main-frame, and span- Vroo two arched braces c, c', connected at top by two transverse bars c2, c3, which are L-shaped in cross-section, and are separated to form between them a guide -way c4. Passing through the arched brace c at its lower ends and 'at its summit, are three screw rods D, D', D2, whichv extend over to the other arched brace c'. The lower screw rods D, D', pass through screw-threaded openings in the lugs, d, of an oblong frame composed of curved or sagging side-pieces d', d2 and end-pieces d3. The master-wheel is located between the sidepieces d', d2, and is journaled in the upright frame or support d4. The two upright bars d5, da, pass through vertical openings in the master-wheel frame, d4, and are connected and supported by a cross-piece (Z7 at the top. A lug dx projects up from the cross piece Z7 through the guide-way c4, and is formed with a. screw threaded opening for the passage of the screw-bar D2. The cross-piece or headblock d7 is fitted in the guide-way c1 between the transverse bars c2, c8 so that it may slide transversely of the machine and the masterwheel frame d4 is fitted loosely on the upright bars d5, d6 so that it may slide vertically.

As in my last patent above referred to, I project upwardly from the master-wheel frame d4 a screw-rod d8 which passes through the cross-piece d7, and between the transverse bars c2, c3. Its lower end turns in a socket in the master-wheel frame, and surrounding it between the cross-piece d7 and a sprocketwheel di thereon is a strong spiral spring d10, which supports the left side of the machine.

E is a sprocket chain which passes over a sprocket wheel e on the outer end of screwrod D, and also over a sprocket wheel e on a crank-shaft e2, turned by a crank esand supported in a bracket e4 at the front end of beam a3. A sprocket chain E passes over a sprocket-wheel e5 at the top of the arched brace c and over a second sprocket-wheel e6 on the screw-rod D. Another sprocket-chain E2 passes over a sprocket-wheel e7 on the screw-rod D' and also over a sprocket-wheel eX on screw-rod D2. Chain E2 is actuated by the chain E through the medium of a short sprocket-chain E3 which passes over sprocketwheels es and e9, respectively on the screwrod D2 and on the short shaft ew which carries the sprocket-wheel e5. The operation of all these parts will be described hereinafter.

In order to carry the drive-shaft, and its gear connection with the operating parts which cut and carry the stalks to the rear, up and down with the master-wheel frame as would be necessary when the machine passes over rough ground or while the machine is being raised or lowered, I provide the following instrumentalities.

Fisamovableorswinging bracket hinged at f to the master-wheel frame d4. In the outer end of the bracket F is amortise or recess which receives a slide bar f which is retained in adj usted position by means of a set-screwfz. See Figs. 3 and 5. The outer end of the movable bar f' carries the support for vthe gear connections above referred to. This support has a vertical portion F' and a pair of horizontally projecting arms F2, F3, provided with longitudinal open slots or recesses f3 at their outer ends. At one side of the vertical portion F' is a slot or recess f4, in which is supported and journaled one end of the horizontal drive-shaft F4. The other end of the drive-shaft is supported and journaledA in a boy.` f5 on the master-wheel frame d4 and carries a loose sprocket-wheel f6 overwhich and over a large sprocket-wheel E5 on the axle of the master-wheel A', a drive-chain F6 passes. rIhe sprocket-wheel f6 is coupled to the driveshaft by means of a suitableclutchF7 whichA may be operated from the drivers seat (not shown) in any preferred manner. The outer end of the drive-shaft F4 is provided with a bevel gear-wheel f7 which meshes with bevel-gear wheel f8. Wheel f8 is permitted to slide on uprightshaftf9 but is caused to turn therewith by means of a feather and groove connection, f1@ indicating the feather. The' arms F2, F3, support the gear-wheel f8 on shaft ff, and the slots or recesses f3 receive said shaft.

g is an upright shaft alongside the shaft f land carries at its top a sprocket-wheel o around which passes sprocket-chain q2 which also passes around the sprocket-wheel di) on the screw-rod d8. The chain g2 also passes `over a sprocket-wheel g3 on a shaft g4 supported by a bracket F. g5 is a lever whereby .shaft g4 may be turned.

Bevel gearing G connects short 'horizontal shaft G' with the upright shaft g, and bevel gearing Gr2 connects it with the upright shaft G3 which is on the side of the mouth or en trance C opposite the shaft g. A sprocketchain G4 passes around a Vsprocket-wheel G5 on the'shaft G3 and a sprocket-wheel G6 fixed on a screw-rod G7, similar to the screw-rod d8. Screw-rod G7 turns in a socket in the vertical frame G that supports and provides journals for the grain-wheel A2. As upon the screw-rod d? of the master-wheel, I place upon the screw-rod G7 a spiral spring G8, 1ocated between the sprocket-wheelG6 and an upper horizontal beam G9 supported by an upright G10. The screw-rod G7 engages in a screw-threaded opening in the upper beam G9.

When it is desired to raise and lower the main frame with reference to the wheels, to adjust the height of cut, the lever g5 is revolved, thus operating thechain g2, the screwrod d8, and causing the latter to act on the cross-piece or head-block (Z7. This same operation also actuates upright shaft g, horizontal shaft G', upright shaft G3, chain G4, and screw-rod G7. The screw-rod G7 acts on the beam G9 similarly to and simultaneously with the screw-rod d8 or cross-piece d7 and thus the main frame is raised or lowered on the supporting Wheels, according to the direction in which the shaft g4 is turned by lever g5.

' The horizontal movement of the master-` wheel Af andthe parts that must necessarily move with it is accomplished by turning This will cause the horizontal screw-rods D, D', D2, to move simultaneously through the medium of the sprocketchains connected therewith. These screwrods will then act through the lugs CZ and dx, and cause the oblong frame d', d2, d2, to move, and the cross-piece or head-block (Z7 to slide in the guide-way c4 between the parallel L- shaped bars c2, c3, bringing these parts cl7, c2,

' c3, and those interposed and connected with them to the position shown in dotted lines.

Before attempting to move the masterwheel transversely of themachine it will be necessary to loosen the set-screw f2 so that the bar f and the support for the gear connections may be slid inwardly to release the arms F2, F3 from the upright shaft f9, so that parts f', F', F2, F2, and the bracket F may be swung forwardly out of the way.

H is a forwardly projecting beam on the right side of the machine, and H is a diagonal beam running thereto from the rear beam A. Between beams H, H and a is a forwardly projecting beam H2. This beam H2 has secured thereto the guide-rods H3, H4, as in my other patents. C is located on the left of guide-rod H2, and the mouth or entrance h is located on the right of guide-rod H4.

Secured to the front end of the beam I-I are boxes H5 in which is journaled a hinge` rod h', on which latter is pivoted a depressible gathering point h2 having arearwardly extendinglever h3. See Figs. l, 2 and 6. In the front end of the beam H2 is journaled a hinge-rod h4, on which is pivoted a second depressible gathering point h5 also having a rearwardly extending lever h6. These gathering points h2, h5, are -depressed or raised by means of a transverse rock-shaft t', connected with the levers h3 and h6, by means of rock-arms I-l, H7, and pivoted links hX, 71,8. For operating the rock-shaft I employ alever IIS, held at any desired point by means of a pawl H2 and a toothed quadrant H10. The lever is fulerumed on the rod d5, and extends downwardly and is connected with a lateral projection or lug 71.9 on the rock-shaft 71,7, by means of a connecting bar 71,10.

The upright shaft f2, and parallel shaftz' alongside it, both located at the rear of the mouth C, carry cutter-disks I, I,'whereby the stalks entering said mouth are severed. The parallel upright shafts i2, ft2, at the rear of mouth h carry cutter-disks I2, I3. Toothed endless carrier chain I4 passes over wheel 'i4 on shaft f2 and operates upright shaft I5 at rear beam a through wheel 5 thereon. Toothed gearing 6 communicates motion to shaft I6, being located at the lower 'cnd'thereof and of shaft I5, while a sprocket chain i7 passing around sprocket-wheel is on shaft IG communicates motion to the cutter shaft e' through sprocket-wheel i2. Toothed endless carrier-` The mouth or entrance chain I7 passes around wheel Is on shaft I6 and operates cutter-shaft t3 through the wheel I9. Cutter shaft t2 is operated by horizontal shaft J leading from cutter shaft t'.

j is bevel gearing connecting shaft t' with shaft J, and L7'2 is bevel gearing connecting shaft J with shaft 2,while ,js indicates the boxes on beam G9 iu which the shaft J is journaled.

In practice it is found that down-corn lying at different angles to the machine must be treated differently with respect t0 elevation in order to bring it in an approximately upright position before it is cut. Corn which lies away from the machine will be cut before it is elevated and so go through endwise, and the same with corn which lies toward the machine. Now in order to effectuate the entering of the stalks in upright position, I make a change of speed by providing a shiftable speeding device for the toothed or lugged elevator chains K, K. These chains pass over sprocket-wheels 7c, 7a' at their lower ends and operate the short toothed elevator chains K2, K3, of the depressible or supplemental gathering points h5, h2.

k2, k3, are the sprocket-wheels at the inner ends of chains K2, K2, and 704, 765 the wheels at their outer ends. Wheels k, 7a2, and la', 7a3, are

fixed on their respective shafts, z'. e., the hinge- I rods h', h4.

The mechanism for changing the speed of `the lagged elevator-chains K," K', is operated by means'of a horizontal lever L pivoted at l to the beam a', and held to setposition by means of a catch Z which takes into notches in the horizontal rack L. Connecting rod L2 extending from the lever L operates the vertical lever L3, pivoted at Z2 intermediately of its ends. The upper end of the lever L3 is formed with a fork Z3 which 'embraces a tubular section or sleeve L4 and may cause the -same to slide on the shaft J. This tubular being the tongue. Above the shaft .I is another parallel horizontal shaft M journaled in boxes m, m', projecting from the beam G9 and the standard M'on the beam H2. Carried by the shaft M are three cog-wheels M2,`M3, M4 of graduated sizes, which may intermesh with the other graduated wheels, wheel M2 being the largest, wheel M4 being the smallest, and wheel Ms the intermediate one. Also on the shaft M is a sprocket-wheel M5 over which a sprocket chain M6 passes and extends up to and passes over a sprocket-wheel m2 on a short shaft m3 located at the top of standard M. The sprocket-wheel m4 over which the upper end of the elevator chain K passes is also carried by the shaft 'm2, so that when chain M6 is operated theelevator chain K and IOC IOS

troV

the supplemental forward chain K2 are both operated to elevate the down corn.

N is a vertical lever pivoted at its upper end to the beam G2, and pivotally connected with the lever L3 by a rod N. The lower end of the lever N is pivotally connected with the lower end of vertical lever N2 by means of a connecting rod N5. The lever N2 is located on the right side of the machine and is piv- .oted at N4, intermediately of its ends, to the scribed, only in reversed order, obviously n3 being the large 4cog-wheel, a5, the small one and n4 the intermediate one. The cogwheels may be slid along the shaft n by the fork as at the top of the lever N2. Journaled in the frame N6, above the shaft n, is a short shaft n, carrying three graduated cog-wheels a7, n2, 'm9, which may intermesh with the graduated wheels n3, n4, W5. m7 is the smallest wheel, 'n.2 the largest, and n.8 the intermediate wheel.

The shaft a5 when in motion, operates the elevator chain through the sprocket-wheel N9 thereon and over which. its upper end passes, while said chain operates the supplemental forward chain K2'. The latter operates the side cutters NX, and the endless chains'KS,

K', carry the stalks severed by these cutters up onto the chute N40 and into the mouth h in approximately vertical position, as in the patents referred to.

From the description of the elevator chains K, K', and the parts which operate them itis evident that by properly moving the lever L either the small cog-wheels L5, r1.5, may be caused to mesh with the large cog-wheels M2, 'n9 or the intermediate cog-wheels L5, n4 with the intermediate cog-wheels M5, fas, or the large cog-wheels L7, 'n3 with the small cogwheels M4, W7, thus changing the speed of said chains.

The shock-forming frame B is connected to the main frame by long links B, B2, the former being located on the left or stubble side and the latter on the right side of the machine. This allows the shock -forming frame to be swung around the master-wheel A to a position nearly central of the mainframe, when the machine is to pass throughv gateways or between stumps. See dotted lines, Fig. 1. The link B is much longer than the other and is pivoted to the mainframe as far forwardly as possible, so that it may be swung around together with the shock-forming frame to which it isl pivoted as far rearwardly as possible.

The shock-formingframe B passes at its vfront edge between and is guided by the lugs B3 on the beam ct of the main frame.

To more eectually sustain the weight of ythe shock-forming frame on the master-wheel and cause the same to move with the masterlwheel when the screw-rods D, D', D2, are operated, I employ a hinged support consisting of an arm B4 and a brace B5. This hinged sup- 'port is pivoted on the upright bar d5, and it is connected to the link B by slot and pin B5.

Attached to the rear beam a by pivot b is a bar B7, which is connected to the shock-forming frame by a removable bolt b', to permit the bar to be swung into the position shown in dotted lines when the shock-forming frame is to be laterally shifted.

The corn entering the mouths C, h, is severed by the cutters, and is carried back by the endless chains I4, I7, through the passages formed between the chains and the guideframe b2, and out through the opening be- ;tween the vertical shafts l5, l5, and onto the floor of the shock-forming frame B. From this point the stalks are carried back onto the revolving shock table O by means of the toothed endless chain b2 and 'the serrated carrying bar h4 as in my latest patent. The carrying bar b4 is operated by a short 'sprocket-chain b5 leading from the shaft l5,

and the chain b2 is operated from the shaft l5.

l will now describe the improvements in the shock-forming frame and its attachments.

As in my former patents the revolving shock table O has a circular skeleton frame O open at the rear, and turns within the curved base o of the shock-forming'frame.

O2, O5, are the rearwardly projecting hingerods on which the leaves O4, O5, of the table are pivoted and on which they are upheld in horizontal or normal position by the springs O5 coiled upon the rods.

O4 indicates the inner pair of leaves and O5 the outer pair. The outer leaves O5 are supported by means of pivoted catches. See Figs. 8, 9, lO and ll. These catches each comprise a vertical pivot pin P which is journaled in a bearingP projecting from the inner side of the frame O of the table.

P2 is a lateral projection at the top of the pivot-pin P having at its outer end a pendent cam-faced piece P3. The lower end of pivotpin P receives a trigger-arm P4 secured to it by a set-screw P5. From'above, see Fig. 10, it will appear that the lateral projection P2 and the trigger-arm P4 extend diametrically opposite. The trigger-arm passes through an opening P5 lin the frame O and is thrown nor- .mally outward by a spring P7 between it and 'said frame. When the trigger-arm P4 of each catch is thrown outward thelateral projection P2 is thrown inward, thereby supporting the leaves O5 so'that they may uphold the incoming stalks. When the table is revolved to the proper point to dump the bound shock, cam-faced lugs P8 on the inner side of the `base o trip the trigger-arms P4 forcing them inwardly, against the action of the springs,

IOO

. the leaves O permitting them to open.

and release the lateral projections P2 from The springs will again throw the lateral projections P2 inwardly, but when the leaves O5 are returned to normal position by their springs O6, theiredges will act on the cam-faced pieces P3 and throw the lateral projection inwardly so that the leaves may pass.

The catch for the central pair of leaves O4, see Figs. 7 and 9, consists of a pivoted button p located in an opening p in the central rearwardly extending bracket p2 forming part of the skeleton 'frame O. The outer ends of the button p are provided with pendent camfaced pieces p3 similar in shape and function to those of PB of the outer catches. A sliderod p4 extending alongside the bracket p2 and guided through a perforated lug p5 at the side of the latter is pivoted at its inner end to one' end of button 29, while its outer free end passes through an opening in the frame O. Coiled around the slide-rod p4 is a spring p6, located between the lugl 135 and a projection p7 on the slide-rod, the tendency of said spring being to project the free end of the slide-rod through the opening therefor, and draw the ends of the button p under the edges of the inner leaves O4, thereby supporting them. Simultaneously with the release of the catches from the outer leaves, the catch of the inner leaves is released by means ot' a cam-faced lug p2 on the inner side of the base o which comes in contact with the outer end of the slide-rod, and forces it inward against the action of spring and turns the button 2J, thus permitting leaves O4 to drop.

' As in my previous patents, I provide the revolving shock table with a central partition, against which the incoming stalks are packed, which causes the table` to revolve within the outer frame. Besides the base 0 the outer frame is composed of the usual top o', posts o2 securing the latter to base o, the hollow columns o3, in which the knotter and needleshafts revolve, the upper gate member o4, the lower gate member 05, and the posts o6 connecting the gates. In the present instance, see Figs. 3, 7, and 12, said central partition is constructed as followsz-q is the foot-plate secured to bracket p2 in any suitable way. Extending upwardly from the foot-plate q is a hollow support q', into which the lower end of the standard q2 is inserted and in which it may be adjusted in height by means ofasetscrew q3 passing through a longitudinal slot g4 in the support q and entering the standard. At the top of the support q is located a forwardly projecting ribbed arm g5 having a short vertical extension or lug Q6 provided with a pair of perforations Q7. The standard j q2 is passed loosely through an opening in a rearwardly extending arm Q provided at its outer end with a downward extension'or lug Q. The latter has a pair of perforations Q2 (shown in dotted lines) which are coincident or in line with the perforations q". The lower semi-circular formers Q2 have fixed to them extensions or plates Q4 which extend longitudinally forward and laterallyrupward at right angles from the formers, as is clearly shown in Figs. Zand 7. The plates or extensions Q4 are preferably formed with flanges by means of which they can be conveniently secured to the formers as shown in Fig. 2. The formers Q3 are provided with pivotpins Q5 which have bearing in the 'perforations of the lug Q2, while the extensions Q2 are provided with pivot-pins QG which have bearing in the opposite perforations of the lug Q6. The formers Q3 and their troughq2, (shown in dotted lines in Fig. 7,) as clearly set forth in my former patents. The extensions Q4 serve to limit the movement of the formers Q3 on their pivots byengaging theV upright q2 and extension q2 at the extremes of their movement, and also to more effectually open the shock when it is dropped upon the ground, so as to make an easy exit for it and render it less liable to catch on the formers.

Coiled around the standard q2 and resting upon the arm Q is a spiral spring R which aiords a resilient support for the depressible crowning-piece R of the partition. This crowning-piece is composed of a tube R2 which lits over the upper end of the standard q2 and which has a longitudinal slot R2 through which a pin or set bolt stud R4 from the standard projects. Projecting rearwardly from the top of the tube R2 is a downwardly slanting bar R5, the lower end of which is connected with the tube by a horizontal har RG. To the bar R6 the upper semicircular formers R7 are pivoted, and these are upheld by the springs R2.

piece R is to provide a resilient support so that when the shock is dropped the binding will not be torn oit.

In order that the shock maybe bound more tightly at the top, l provide a compressor now to be described, reference being had to Figs. l, 3 and l2. The compressing attachments are located on the top o olf-the shocktigous ends ot' the shaft are connected by intermeshing bevel-gears S2. These bevelgears permit the shafts to operate simultaneously, and also to separate when the gate is swung on its hinge s2, Fg.12. Projecting upwardly and inwardly from these rockshafts S2 are arms s3. 'lhe upper ends of the arms carry curved compressor segments S4 forming a continuous curve which is a complete circle, when viewed from the top, with shaped extensions Q4 are upheld by springs IOO (Shown in dotted lines in Fig. `7.) The object of this depressible crowningthe exception that the portion opposite the entrance to the shock-forming frame is open.

The number of compressor segments S4 corresponds to that of the rock-shafts S2 which carry them, and they overlap at their extremities, alternate onesbeing situated on a plane above that of theirintervening neighbors. Thus placed their ends will notinterlock when they are operated. To actuate these segments S4 at the proper time and simultaneously I project from the hub of the needle T an arm t, to which a rod t is pivoted, having at its outer end a head t2.. I

s4 is a slanting pivot-bolt conforming to the slant of the needle-shaft. 0n this pivotbolt turns a bell-crank lever, one end of which 35 is connected with the rod t', and the other end s6 runs grainward and is formed with an upward extension S7 which presses against the compressor segment nearest the needle. To form a resilient or elastic connection between the bell-crank lever 55, s6 and rod t I surround the llatter with a spiral spring t2 located and confined between the head t2 and one end of a pivoted piece t4, through one end of which the rodV passes. The other end of the piece #is connected to the arm S5 of the bell-crank lever by a pivot or set-screw t5 which passes through a slot t5 in said arm.

It will be apparent from this description that when the needle T moves forward the compressor segments S4 are all simultaneously operated to press tightly together the top of the shock so that a tight bind may be elccted.

To support the compressor-segments of the gate in proper position, when the gate is opened I attach to one of the segments S4 and to the top member of the gate, a spring S6 and a cord or strap S7.

T is the knotter-shaft and T2 the needlel shaft, both moving within the columns o2, 02,

on each side of the entrance of the shockforming frame.

No knotter is shown, but an ejector discharger 'I3 is shown on the knotter-shaft, which at the proper time forces the shock rearwardly.

In `practice it is found best to bind the shock before the table is moved by its'actu ating mechanism, after the shock is fully made. The devices for causing the knotter, needle and table actuating mechanism to operate at the proper time are similar to those described in my before-mentioned patents, and they are hence not fully shown, nor will they be described at length. It will be sufficient. to state that U is the loose cog-wheel on continuously revolving shaft u, U is the trigger, u the detent or bell-crank pivoted `on the needle-shaft T2, and U2 is the spring the force of which the lug u2 on the frame O of the table counteracts when it comes in contact with one end of said bell-crank so as tok iV2. -portion with a continuous series of cogs o,

lcarries a spring-actuated dog, and formed on its hub is what may be termed a Geneva stop gear, consisting of a boss or circular enlargement w having a cut-away or recess to2 in itsV periphery conforming to the curvature of the peripheral flange V3. This cut-away w2receives the edge of the flange. When the `shock is fully made and the tripping mechanism is actuated the gear-wheel W2 has engaged the rack-teeth 105 of the revolving table Oand when the circular flange V3 of the wheel V has passed the cam portion on the hub of wheel w3 the same begins to revolve and the spring-dog w catches in the ratchetteeth of wheel W2 and drives it forward with it until arrested by the samson wheels W8 and V driving` the revolving table home.

The construction of the actuating mechanism for the knotter-shaft, needle-shaft and table being as described, I will now proceed to describe its operation.

Wheel U being set in motion, which occurs just as the revolving table is about completing the revolution imparted to it by the incoming stalks, gear-wheels W, W', are operated to cause the large gear-Wheel V to rotate which operates the knotter, not shown, and therneedle. During a little more than the first half of the revolution of wheel V, the flange V3 ispreventing the rotation of the wheels W2, W3, caused by the edge of the flange being in engagement with the side w2 of the cam. As soon as the flange passes the cam, the circular series of cogs 'U' commence to act on the small gear-wheel W2, and continue to rotate the latter until the iange comes around bagain, at which moment the actuating mechanism is brought to rest. The revolution of the gear-wheel W3 moves gearwheel W2 through the medium of the ratchetteeth o n gear-wheel W2 and the spring-dog arm on gear-wheel W3 and brings its springdog arm against the ratchet-teeth wx, imparting and insuring an initial movement to the j IOO IIO

revolving table, and causing the series of teeth or cogs 'L05 on the latter to be driven home. The latter will now positively rotate the table until the shock is dumped or deposited on the ground, which is permitted by the opening ot' the leaves O4, O5. Besides having on the lower member o5 of the gate a projection or hook m as in my last patent, I place a similar projection or hook upon the upper member o4. See Fig. l5. The lower` pivoted catch x2 and the upper pivoted catch m3, which `catches respectively engage the projections or hooks x', are connected by a rod x4, which causes the catches to be released simultaneously, to allow the gate to open and permit the exit of the shock. rlhe release of th'e catches is caused by the lug x5 coming in contact with the projecting end of pivoted catch x2.-

The bridge which supports the incoming stalks when the leaves of the table are open is in the present invention made in three folding pieces which practically cover the space to the vertical partition. Two members y, y are pivoted at y2, and the other member g3 is pivoted under the member y on the stud y and is connected with the pivoted arm g4 by the crank arm yl and link Ll/8, in the same m-anner as shown in my Patent No. 470,609. The member Lt/3 folds under member y as the arm g4 is moved by the vertical partition of the table, and the member y is connected with the member y by slot and-pin connection g5 so that the members y and ys may fold-under member y. This construction ot bridge requires less space when folded.

The leaves of the table are in practice mad about three inches less in diameter than the frame O, so that there will be a space between the latter and the leaves of about one and one-half an inch. This will diminish the liability of obstructing the return ofthe leaves to closed position should any loose material be left after the shock has passed out.

In order to form a rolling interior surface to the base o, the top o', and the top and bottom of the gate of the shock-forming fratrie, I provide au upper and a lowerseries of wheels or rollers z z', respectively, which are mounted on suitable journals z2. Those at top are located underneath the top 0', and

the top of the gate while those at bottom are located on top of the base o and the bottom ot' the gate. These Wheels or rollers are preferably inclined downwardly and inwardly so as to obstruct the downward passage ofthe shock as little as possible when the leaves are dropped. The object of these idle wheels or rollers is to` form a rollinginterior surface to relieve the carrying bars or packers of the heavy pressure that is incident to the stalks sliding against the inner sides of 'the beam, while the shock is being made inside.
