SHEAF SHOCKER.

Application filed June 30, 1921. Serial No. 481,565.

To all whom t may concer/n.:

K Be 1t known that we, ARTHUR PERRIN and GEORGE ALBERT BAssE'rT, both subjects of the King of Great Britain and both residents of the town of New Liskeard, in the Prov-y ince of Ontario and Dominion of Canada, are the executors of the estate of the late VILLIAM HUivirI-IREY PERRIN, who during his lifetime was a resident of the said town of New Liskeard, and who invented certain new and useful Improvements in Sheaf Shockers, of which the following is a specilication. i

This invention relates to improvements in sheaf shockers, particularly to those of the type in which the sheaves are 11p-ended as they are discharged from the binder and caught on suitable hooks which rotate in a horizontal plane and are adapted to simultaneously discharge the sheaves in the form of a shock.

One of the objects of the invention are to provide simple improvements in the form of a sheaf gripping hook to enable it to better engage the sheaf and support it in upright position prior to discharge7 and such form of hook as may serve as a guide for the sheai during its discharge.

Further ob]ects are to provide an im* proved guide means for guiding' the sheaf from the binder deck to the hook of the shock forming member.

Further objects still are to provide improved means for engaging the outer portions of the sheaves on the hook prior to discharge and shaping them to form a proper shock.

Further objects still are to provide an im proved support for the centre of the sheaves while on the hooks and prior to discharge.

Further objects still are to provide an improved form of slide for guiding the sheaves from the binder deck during 11p-ending and engagement with the hook.

Further objects still are generally to improve and simplify the construction of the device to better adapt the various parts to perform the functions required of them.

It consists essentially of the improved construction hereinafter described in detailin the accompanying specifications and drawings.

In the drawings, like characters of reference indicate corresponding parts in all the iigures.

It may be stated that many parts of the present invention are similar to those shown in my United States Patent No. 1,346,974 granted July 20, 1920.

Referring to the drawings:

A indicates the binder deck, below which is operatively mounted a rock shaft 10 provided intermediate of its length with a compresser arm 11 mounted on a shaft 11a and bentto form a crank 12 connected through a link with a sprocket 14 mounted on a transversely extending tying shaft 15. The sprocket 14 is adapted to actuate the tying mechanism fowrtlie binder, the parts of which are of well-known construction in the artv and have been clearly shown and described in applicantis Patent No. 1,346,974 for sheaf shocker, patented July 20, 1920.

During its discharge from the binder deck, the sheaf is adapted to be rip-ended by mechanism described in detail in the aforesaid patent and including a supporting member 1 having arms 2 and 3 connected to opposite sides thereof, the outer ends of the arms being pivotally connected to the offset delivery arms 4 and 5 intermediate of the length thereof. The shorter ends of the delivery a rms are provided with rollers 6 and 7 adapted to co-operate with cams 8 and 9 mounted on the fixed `sleeve 30 which surrounds the knotter shaft.

By reference to Figures 3 ,and 16 in the drawings, it will be seen that the cams 8 and 9 are located on opposite sides of the membeil 1 and yare so arranged relatively to each other that the roller 6 on the arm 4 will become disengaged from the cam 8 prior to the disengagement of roller 7 on the arm 5 from the ,cam 9 so that the arm 4 is free from the butt of the sheaf, allowing' it to drop .downwardly while ,the delivery arm 5 .continues ,on moving in an upward direction on its co-acting cam and, therefore gives the head of the sheaf a greater throw than does the arm 4, thereby facilitating the 11p-ending of the sheaf into a vertical position. i

Located intermediate of the compressor arm 11 and the crank member 12 of the rock shaft 10 is an adjustable crank member 23 provided with aV bifurcated end having pivotal engagement with Ithe offset arm 24 of a linger 2,5, which is adapted to co-operate with a lcurvilinear cam race 2,6 operatively supported below the binder deck A adjacent to the said adjustable crank member so that, on actuation of the rock shaft 1 0, the linger is right .over the outer end of the cam race and will be elevated ,or lowered (see Figure 10). f

The butt :of the sheaf is ,designed to be supported by the linger 25 which, during the depression of the compressor arm, is elevated hy the rotation ofthe shaft 10, causing the upper or inner'end of the said finger to en `age with the edge of the cam surface 26 wiich causes the linger to be angularly disposed upwardly, thus holding the butt of the sheaf in the desired position. ldhen in this position, the sheaf is also engaged by the Z-shaped compressor arm 66, the upper end ofwhich is pivotally connected to'an arm pivoted to a standard 29. rlhe compressor arm 66 normally extends horizontally and has its outer end bent downwardly at 67 so that it may engage with the butt of the she-af after it has passed the compressor arm 11 to compress the said butt.

The compressor arm G6 is provided adjacent to its pivoted end with a strap 68 to which one end of a spiral spring 69 is anchored, theother end being secured to an arm 68a so that, when the arm 66 is displaced on the delivery of the sheaf from the hinder deck, the said arm will be returned to its normal position under the action of the spring, (see Figure 15).

The sleeve 30 surrounding the shaft 15 engages and supports one end of the standard 29, the other end of which unites with a similar standard 29a. The lower end of these standards extends around the tying shaft 15. rl`hese standards together support the sleeve 30a which extends in a stubbleward direction and constitute part ofthe supporting mechanism of the shock-forming means. The sleeve 30u is supported intermediate .of its length from the. standards by braces 31. The standards 29 and 29n are united lat their upper extremity by a bracket 29b which is connected to the sleeve 30k The binder deck A is provided at the discharge end and towards the rear thereof with an extension B consisting of a curved guide plate 100 hinged to the binder deck and which is curved upwardly a short'distance and has hinged to its upper extremity a supporting plate 101 movement of which is controlled by means of a connecting link 102 having one end 103 bent laterally and engaged with the l'iinges 104 between the n'ienihers 101 and 100, the oppositie end of the link being pivotally connected to a crank 105 on the knetter shaft 15. The outer end of the supporting plate 101 is rigidly supported by means of a rod 106 having a laterally turned end 107 pivotally connected to brackets 108 on the plate 101, the opposite end of the rod 106 being connected `to a brace 109 which extends laterally from the sleeve 80a being connected thereto by a U- bolt 110. i

1t will be seen that as the knotter shaft, turns, the movement the crank 105 will swing the hinges of the plate 100 inwardly which will raise the upper end of the plate 100 while depressing the upper end of the plate 101 as hereinafter more fully explained.

The shock forming mechanism C comprises a plate 32 formed on diametrically opposite sides with lugs 32a which are formed with an upwardly extending projection 33 adapted to engage the sleeve 30a above which a plate 35 is secured by bolts 36, the plate 35a being provided with spaced lugs 111 which support a pin 112 which pivotally retains the hook-shaped end 113 on an arm 114 which extends rearwardf ly and downwardly, the lower end of which supports a cord 115 which is designed to extend around the sheaves, as hereinafter explained. @ne end of the cord is fixed to a lug 116 on the arm 114. The cord is looped a distance from the end and is extended through an eye 117 in the lower end of the arm 114, the slack in the cord being taken up by means of a take-up member 113 having an eye 119 at its lower end through which the loop in the cord 115 extends, the free end o1 the cord being connected to one cit' the arms 129, as hereinafter described.

rlhe upper end of the arm 118 is curved horizontally and supported by one arm` ot a crank 120, the crank being pivotally connected to a brace 121 secured by suitable bolts 122 to the sleeve 30a, the cranlr 120 being adapted to return to normal position when moved therefrom under the action of a spring 123 which extends from one arm of the crank to the brace 121.

The plate 32 is provided on its lower face with a downwardly extendingboss 34 to which is connected a vertically disposed and non-rotatable shaft 38. The plate 32 is superimposed on a gear 39 which is rotatably mounted on the shaft 38, being supported by a collar 124 on the shaft which is locked in position by a set screw 125. Intermediate of the boss 34a and the centre of the gear 39, a cup-shaped tripping inember is located and is rigidly secured in position relative to the gear by the spring controlled detent 39a which engages the serrations 72 in the radial flange 71 on the tripping member. r1`he lower portion of the cup-shaped tripping member is provided with peripheral pocket 7 3 adapted to engage with a vertically disposed rod 35 carried by a star-shaped connecting member 48 rotatably mounted on the shaft.

Turnably mounted on the upper end of the shaft 38 is a lever 90 provided intermediate ot its length with an inverted U- shaped bracket 91 `carrying a spring controlled detent 92 designed to engage with the serrations 72 in the flange of the tripping member 70. The outer edge ot' the lever is connected to a rod 93 which extends to a point adjacent to the drivers seat so that the tripping member may be manually turned when it is found necessary or desirable. The gear 39 is provided with peripherally radially extending lugs 43 to which the supporting arms 126 are pivotally attached. As shown six arms are provided. Each arm comprises a lever member 127 pivoted intermediate of its length to the lugs 43a and having at its upper extremity a roller 128 designed at one point in the revolutions of the gear 39 to be engaged by a ixed cam 76 which is V separated a distance outwardly from the gear and designed to swing the upper end of the lever 127 inwardly, thus swinging the lower end outwardly.

The lower end o the lever member 12T is connected to a rod 129 which is formed with a laterally turned portion 130 at its lower end extending substantially at right angles to a radius passing through the centre of shaft 38. This extension 130 carries a hook member 131 r`formed,with a laterally extending prong 132 and an intermediate portion 133 which is journalled in eyes 134 on the portion 130 and terminates in an outer hook 135. The prong 132 is con siderably longer than the hook 135 and is designed to give considerable support to the shear and form a guide for it during the action of discharge.

During discharge the hook member 135 is designed to swing downwardly by means of a link rod 136 connected to the prong 132 at its lower extremity and adjustably connected at its upper extremity to a link 137, the opposite extremity of which is connected to the extremity ot a lever 138 which is fulcrumed intermediate of its length to a bracket 139 connected to the gear 39, the opposite extremity of the lever 138 being connected to the member 48 by a link 138% The adjustable connection between the rod 13G and the link 137 is effected by means of' a perforated lug 140 on the link 137 through which the rod 136 extends and is adjustably held by means of nuts 141 on a threaded portion of the rod 136. The arms 129 are retained in normal and innermost position by means of tension springs 142 extending from the rod to the star-shaped member 48.

Support is given to :the centre of the shock and the formation thereof assisted by means of a central core member 143 mounted on the shaift 38 and formed with a plurality of 'liutes 144 which are semi-conical in shape, gradually widening towards the bottom whereby the sheaves will be compressed by the liutes at the top but be free to expand at the bottom. The tintes are also deeper at the bottom than at the top.

Additional support is given to the sleeve 30a and the shocle'forming member by means of a tie rod 145 extending from the pin 112 on the plate 35a to a rod 146 which is secured to the member 29, the rod 146 being supported by an adjustable tie rod 147 which is connected at its lower extremity to the binder; the adjustable comiection in the embodiment illustrated being formed by a laterally turned eye 148 on one portion of the rod which lits a screw-threaded portion formed on another part of the rod being held in adjustable position thereon by a nut 149. By adjusting these nuts, it is possible to adjust the height of the shock-forming member, the arm 146 and the members 29 and 29a turning about the lower end of the members 29 and 29a which are pivotally supported tor this purpose.

Rotatably mounted in the sleeve 30"l is a shaft 41 driven thrcugh the gears and 45a from the vertical shait 44n which is driven from the knetter shaift by the gears 15a and 10, (see Figure 1(3). The end ot the shaft 41 remote 'from the gears 42a and 45a is provided with a gear 40 adapted to mesh with the 39 ci the shock-torming mechanism C.

1n order *tov iurther guide the sheaf during upturning, 1 provide a curvilinear guide rod extending above the member B and substantially parallel therewith, being connected at its upper end to the sleeve u and at its lower end to a portion 150a ci? the binder.

V1n the operation of the invention, the sheaves are delivered in. the ordinary operation of the binder against the compressor arm 11 and owing to the rotation ot' the sprocket 14 by the binder mechanism the rock shaft 10 is actuated through the link 13 to turn the said arm and so allow the sheai to be delivered to the stubble side of the deck A where the head oi' the shear will rest on the platform 13. The bottom of the shear is supported by the finger 25, as already explained, and is also engaged by rompressor arm GG and is held in this position until the delivery arms 4 and 5 discharge the shea'f from the 'binder deck A.

1t will be seen that the rollers 6 and 7 et the delivery arms 4 and 5 will, on rotation oi the member 1, engage with the stationary cams 8 and 9, and, since these cams are arranged in such a manner that the delivery arm 4 is disengaged from the cam 8 prior to the disengagement of the delivery arm from the cam 9, the bottom of the sheair will be allowed to fall slightly downwardly since it is vtreed earlier from thedelivery arm than the head, which will be thrown upwardly by the delivery arm 5, so facilitating the up end of the sheai.

The Lip-ending of the shear is further assisted by the movement of the member 100 which is moved upwardly and inwardly b the operation oi' the crank 105 and rod 1.02; at the same time the outer plate 101 is moved downwardly about the hinges 104, which gives a clearance to the sheaves and permits them to pass by the upper part of the member B. The sheaf, when discharged in an lip-ended position, is engaged by one of the hook-members 133 on the arm 129 of the shock-forming mechanism. 1t will. be understood that simultaneous to the operation of the rock shaft 10, rotary motion is transmitted to `the shaft 41 on the binder mechanism so that the pinion meshing with the gear 39 causes the shock-forming mechanism C to be rotated so permitting the hook member 133 of each arm 129 to be engaged with a shea as it is delivered from the binder deck A, the arm being thrown outwardlyin a proper position for this purpose by action of the roller 128 enga-ging the cam 76.

The inner ends of the sheaves are supported by the core member 143, being held against the same by the arm 129 and hook members 133. T he sheaves will also be held in position by the cord 115, the end of which is connected to the arm 129, so that the said cord will extend on the outer side oi the sheaves and will be wound around them. When the shock is finally discharged, the slack in the cord will again be taken up by action of the member 118, as previously explained.

Willen the hook members 133 are all iilled, the rod 35 will come opposite to the recess or peripheral depression 73 in the cupshaped-tripping member 70, and the weight oit the sheaves on the hook members 133 will cause the star-shaped member 48 to be eleated, actuating the lever 138 and depressing the hooks through the rods 136, so permitting the sheaves to be simultaneously discharged in the form of a shock. During this operation, the flexible member 115 will surround t-he heads of the sheaves, binding the same together to gire the best possible form ot shock.

i/Vhen the machine has reached the end 0i the out, it may be that the number of sheaves gathered by the shock-forming mechanism C is not suliicient to form a complete shock and, therefore, will not automatically drop the sheaves bei''ore a new cut is started. 1n order to accomplish this, the driver of the binder operates the link 93 thereby turning the lever 90 above the upper end 0i' the shaft 38; the detent 92 will thus engage with the teeth 72 and rotate the tripping member through a predetermined distance for each movement'orn the lever until the peripheral pocket 7 3 engages with the rod 35 of the star-shaped member 48, allowing the same to be elevated and so drop the sheaves carried by the hook members 133. The lever 90 being retracted by hand, when necessary, to its original position.

1t will be seen that the 'form of hook members 133 designed is adapted toI eifectually support two sides of the shock and so hold the same in proper position during formation of the shock. 1t will be seen also that the flexible member or rope 115 does not drag on the ground as in my earlier patent butthe slack is taken up by means of the spring actuated member 118. The grooves or flutes in the core 143 serve to guide the sheaves in dropping in the form of a shock and also to maintain them in proper position during the Ashock-forming operation. 1t will also be seen that the member B together with the guide rod 150 forms an efasians@ fectual guide and slide for each-individual sheaf during discharge, and yet the upper part of the member B is moved out of position to give clearance for the movement of each sheaf during discharge.
