SHOCKING MACHINE.

Application filed April 15, 1922. Serial No. 553,068.

To all 40710121 it may cmwem:

Be it known that I, WILLIAM JAMES Coom-aunx, of the town of Superb, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Shocking Machines, of which the following is the specification.

The invention relates to improvements in shocking machines and an object of the invention is to provide a shocking machine which can be readily attached to a binding machine at the deck side thereof, will receive sheaves ejected from the deck, form them into a shock and deposit theshock, butt down. and firmly planted on the ground.

A. further object is to provide means for spreading the butt of the formed shock prior to depositing, thereby giving it a well spread base.

A further object is to provide a basket construction which will form the sheaves placed therein into a good shaped shock and will maintain the formed shock in good shape, until it is ready to be deposited on the ground.

A'still further object of the invention is to provide means for overcoming the momentum of the deposited shock so that it will not upset forwardly after dumping and also to forcibly plant the base of the shock on the With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereina fter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which:

Fig. 10 is a vertical sectional view at 10-10 Fig. 9.

In the drawings like characters of reference indicate corresponding parts in the several figures.

The shocking machine shortly disclosed is connected to any of the well known types ofbmding machines at the deck side thereof and is drawn with the binding machine and receives the sheaves deposited from the deck.

forms them into a shock and dumps the shock, with the butts firmly planted on the ground.

I have not considered it necessary to enter into a detailed description of the binding machine as it is well known and I am only referring to those parts ofthe binding machine with which my machine is assocdated.

The frame 1 of the shocking machine is connected by a spacing bar 2 to the binding machine 3 immediately adjoining the bind ing machine deck 4 and the shocking machine is drawn by suitably positioned draw bars 5 and 6 extending angularly forwardly from the shocking machine to the fore truck (not shown) of the binding machine.

The shocking machine frame 1 is substantlally rectangular and has the rear part open and is provided with side extensions 7 and 8 which, with the frame, form bearings for an outer shaft 9 and an inner shaft 10, the'shaft 9 being fitted with a carriage wheel 11 whilst the shaft 10 is provided with a driving wheel 12, these wheels supporting the shocking machine from the ground. The frame is also extended forwardly and is fitted with a swivelled or castor wheel 13 which is disposed to the side of the frame next the binding machine.

Rearwardly and at each side of the shocking machine frame I locate two upstanding stationary standards 14 and 15 which support rotatably an elevated rearwardly disposed basket shaft 16.

On the basket shaft and immediately to therinner sides of the standards I mount rotatably a pair of similar spaced sleeves 17 and 18 and the sleeves are fitted at their inner ends with extension arms 19 and 20, to which I rivet or otherwise permanently fasten the top or closure member 21 of the basket later described. This top or closure member is normally extending upwardly or in the open position, being held there by a releasable clutch member later described and is curved and is of such a size that it can pass through the sheaf entry opening at the top side of the basket and bring pressure on the sheaves therein during the depositing of the shock. It is also constructed so that it can rotate around the basket shaft and without striking the frame or any other member associated therewith.

The outer ends of the sleeves carry pivotally a cradle 22, the cradle supporting a butter 23 which is held normally in the position shown in the drawings by the action of a coil spring 2% attached to the lower part of the cradle and to the fore part of the shocking machine frame.

The batter is provided with comparatively deep side flanges or wings 25 and 26 and it has the upper part thereof normally extending vertically and the lower part thereof curved concentric to the shaft 16. The lower end of the butter is deflected inwardly as indicated at 27 to provide a retarder for the shock which acts as later disclosed.

The sheaf receiving and shock forming basket 28 is of conical shape and has the upper side thereof open to permit of the entry of the sheaves.

The rear end of the basket is provided with a pair of hangers or arms 29 and 30 which are permanently fastened as by pins 31 to the basket shaft and it is designed such that it rotates with the shaft, the forward or large end of the basket swinging down within, but clear of the butter 23.

The basket is held in the horizontal or sheaf receiving position by a comparatively strong coil spring 32 having one end anchored to the frame and the other end attached to a crank 33 secured permanently to the outer end of the basket shaft.

The spring is designed such that it supports the basket normally in the position as shown best in Figures 1 and 2.

T might here explain that as the sheaves are loaded or deposited in the basket the increasing weight of the sheaves causes the basket to gradually swing down, the spring lengthening: but the amount of down swinging is limited by selecting a spring of proper and predetern'iined strength.

To the underside of the basket I attach permanently a pair of transversely extending front and rear bars and 35, the bars forming pivot bearings for a pair of parallel lengthwise extending shafts 36 and 3,7. The shafts extend forwardly a short distance beyond the forward end of the basket and they are there provided with curved hooks or grabbers 3S and 35). The shafts are compelled to turn together, but in opposite directions, by the action of a cross link shafts.

To the rear ends of the shafts 36 and 37 I attach curved trip arms 43 and l which normally extend outwardly from the sides of the basket and in the down swinging action of the basket are designed to engage with and ride trip plates 45 and 46 permanently carried by the machine frame and by angularly disposed brace bars l t and 15 extending between the frame and the standards l i and 15. The trip plates are arranged concentric to the shaf 16.

I might here explain that the action of the trip arms and grabbers is such that preceding the dumping of the basket, that is, prior to the time that the butt ends of the sheaves are swept off the butter, the grabbers are swung in by the action of the trip arms on the trip plates to grab a portion of the butt of the shock and hold it permanently; and they maintain their hold until such time that the trip arms have cleared off the rear end of the trip plates.

The inner end of the shaft 10 is fitted with a bevel pinion 4'? which meshes with a bevel pinion 48 carried by a counter shaft 49 located at the inner side of the shocking machine frame. The rear end of the counter shaft is equipped with a chain wheel 50 and the chain wheel drives through the chain 51 a chain wheel 52 secured to the driving shaft 53 of an upwardly extending inclined conveyor 54. The conveyor is suitably carried by the shocking machine frame and in so far as the present inven tion is concerned the details thereof are not considered important as it is only utilized as a means for receiving the sheaves discharged from the deck r. elevating them and then discharging them into the basket. Any suitable type of elevator could obviously be employed for this purpose it being understood that in the normal or sheaf receiving position of the basket the elevator will discharge the sheaves directly into the basket through the opening in the upper side thereof.

The top or closure member 21 of the basket is utilized to forcibly rotate and dump the basket when suflicient sheaves have been placed therein to form a shock and the said top is controlled directly by an attendant on the binding machine who en- 1 gages a clutch, hereinafter described, and by so doing starts the top 21 rotating in a clockwise direction. Any suitable type of clutch can be utilized and whilst I will shortly describe the clutch which I employ it will be understood that I do not wish to be restricted to the details of the clutch disclosed.

' The particular clutch 55 which I employ is now described:

the rim 58.

To the end of the sleeve 17 next the binding machine I key a female clutch member 56 in the form of a disc having a hub 57 and a peripheral flange or rim 58'. The rim is split and fitted with two inturned tongues or stops 59 and 60 which are spaced apart a predetermined distance and converge toward the centre of the shaft 16.

On the shaft 16 immediately adjoining the disc I mount rotatably a chain wheel 61 which is fitted with a rim 62 which encloses The inner side of the rim 62 provided with rounded teeth 63 and a loose roller 64: is inserted between the tongues and within the rim 62.

On the hub 57 I mount pivotally a ring 65 which is provided with an outstanding wing 66 which extends between the tongues and sufficient space is retained between the wing 66 and tongue 60 to admit and hold the roller so that the said roller can be maintained free of the teeth 63. A lug 67 is formed integral with the disc 56 and a spring 68 is inserted between the lug and the wing 66 and the wing is fitted with an exposed dog or catch 69 projecting freely through a slot 70 in the disc 56' and normally engaged by a spring pressed trip crank 71 secured to an elevated shaft 72 carried by the inner standard 15.

The chain wheel 61 is driven by a chain 75 direct from a chain wheel 76 secured to the shaft 10.

The spring 73 associated with the trip crank is a comparatively light one, its duty being to return the trip arm to its normal position after the operator has turned and released the operating rod hereinafter mentioned.

An operating rod 74 extends from the inner end of the shaft 72 to the binding machine and terminates within convenient range of the attendant where it is provided with suitable means for operating, such as a hand lever,,pedal or crank.

lVith the roller in it will be obvious that the chain wheel 61 can turn freely; on the other hand, if the attendant turns the rod 74: in the direction which will swing the trip crank 71 away from the dog 69 the spring 68 will operate immediately to swing the wing 66 in a direction which will force the roller 64: out into contact with the teeth where it will bind and form a driving connection between the chain wheel and the disc 56 and consequently the inner sleeve 17. When this occurs the chain wheel 61 willdrive the sleeve and will consequently rotate the top or closure member 21 of the basket and the closure member in swinging forwardly will first close the opening in the top side of the basket and will then carry the basket around with it, the spring 32 extending during this action. When the basket and top reach the dumping position the crank 33 is extending upwardly with the result that in the further forward movement of the crank past dead centre the spring '32 will quickly compress and will accordingly swing the basket upwardly approximately three quarters' of a revolution,

when it will again come to rest in the Sheet receiving position, as the crank 33 is then down and swinging backwardly and the spring is accordingly gradually being brought under tension. This quick up and back movementof the basket entirely clears the basket from the deposited shock and as the machine continues to advance and move away from the shock the basket top aids having cleared the teeth, the chain wheel continues to rotate, but does not drive the sleeve 17 and consequently the basket top.

I wish here to point out that the basket top or closure member 21 normally inclines slightly ahead so that it has a natural tendency to rotate the sleeve 17 in a clockwise direction. This tendency to rotate, however, is prevented by the trip crank 71 which is caught on the dog and consequently prevents rotation of the disc wheel. 56 which is fast to the said sleeve.

In connection with the dumping of the basket I might remarkthat as the basket swings down the butts of the sheaves are forced back by the retarder 27 which drags on the butts or the passing sheaves. The prongs or grab hooks 38 and 39, however, hold firmly a few of the butts against backwar'd movement asproduced by the retarder. The sheaves which are not caught by the grab hooks are forced back by the retarder and this action gives the shock a well spread base so that the butt is well spread and planted on the ground. The grab hooks, of course, are timed to release coincident with the swinging away of the basket from the planted shock.

The butt of the shock is forcibly planted in the stubble of the field owing to the fact that the flistance between the shaft 16 and the butter 23 is greater than the distance between the said shaft and the ground and consequently the butt of the upended, but not yet released, shock is forced into the stubble as the machine advances and prior to the basket swinging quickly backwardly and upwardly.

From the above it will be apparent that i that when it is once set in action it dumps the shock, spreads the butt thereof, firmly plants the shock on the ground, prevents the shock from upsetting forwardly and finally resets in the original sheaf receiving position.
