WILLIAM JOHN MILLER AND ALBERT'E. TERRY, OF ROBLIN, MANITOBA, CANADA.

SHOCKING MACHINE.

Application filed March 1, 1924. Serial No. 696,245.

To all whom z't may concern Be it known that we, -WILLIAM JOHN MIL- Lnn and ALBERT- E. TnnnY, both of the town of Roblin, in the Province of Manitoba, Canada, have jointly invented certain new and useful Improvements in Shocking Machines, of which the following is the S136Clfi0it1011.

The invention relates to improvements ln shocking machines and an ob ect oft-he- 1nvention is to provide a machine which can be readily attached to the customary binding machine and which will receive sheaves and form the same into a shock and dump the shock butt down upon the ground.

A further object of the invention is to provide a machine which will form shock and will deposit the shock forcibly and butt down on the ground to firmly plant the same and will also act to cap or draw the heads of the sheaves together and also spread the butts thereof to give the shock a large butt.

A further object is to provide a machine embodying a rotary basket with prongs or fingers which co-act with the basket to prevent premature escape of the shock and also act to spread the butt of the shock.

A further object is to provide a machine which can be controlled by the attendant of the binding machine accompanying the same and one in which the various parts are entirely automatic in their action.

iVith the above more important objects in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings in which:

Fig. 1 is a side view of the shocking mawith the basket in sheaf receiving po- .oi A 1;. 2 is a plan view of the machine. Fig. 3 is a front view of the machine. Fig. 4-. is a vertical sectional view longitudinally through the machine at l4' FE In the drawings like characters of reference indicate corresponding parts in the several figures.

This machine accompanies the customary binding machine being attached to the deck side of the binder in any suitable manner. As such an arrangement is quite common we have not considered it necessary to show the binder or the manner of connecting our machine thereto.

Further it is to be understood that the sheaves discharged from the binder are picked up by an elevator and discharged by the elevator into the basket. Elevators of various types are now in use on shocking machines and as the elevator forms no part of the present invention it is not herein described or shown. It is sufficient for the purposes of our invention that the sheaves be discharged in the basket from the top and as soon as a sufficient number have been collected in the basket to form a shock the basket will handle the shock until the same is deposited in standing position on the field with the butt thereof firmly planted.

Referring now to the drawings it will be found that the shocking machine frame presents opposing, spaced, rearwardly extending side bars 1 and 2, a front connecting cross bar 3 and a substantially L-shaped side bar 4, the forward end of which is fastened to the cross bar and the rear end of which is secured to a horizontally disposed track 5 permanently secured to the rear end of the bar .a. The bar 1 also carries a horizontally disposed track 6 similar to and directly opposits that 5. In the present instance the tracks are channel bars.

The bars 2 and 4 provide suitable bearings for a main or driving axle 7 on which we mount a pull or master wheel 8 and a chain wheel 8. This master wheel carries, what might he called, the inner side of the machine, that is the side that is nearest the binding machine when in use. The other or outer side of the machine is provided more or less centrally, with a crank like axle 9 on which a carriage wheel 9 is mounted. v

Forwardly to the frame we secure a V- shaped horizontally disposed bracket 10 to which a caster wheel 10 is pivotally attached.

To the cross bar 3, in a location within the bars 1 ant 2, we permanently secure two similar upstanding, spaced arms or standards 11 and 12 which have their upper ends turned rearwardly as indicated at 13. To these arms and in a location somewhat elevated above the frame we attach a pair of opposing bearings 14 and 1a which support rotatably a forward cross shaft 15, said shaft having the ends thereof projected beyond the bearing to carry parts hereinafter disclosed.

The inner end of the shaft is provided with a chain wheel 16 which is driven by a chain 16 from a chain wheel 17 mounted on a counter shaft 18, the counter shaft being suitably mounted in bearings carried forwardly by the bars 2 and 4. A chain wheel 19 is mounted on the counter shaft and is adapted to be driven by a chain 19 from the chain wheel 8'. Disengageable clutch members 20 and 20 are associated with the chain wheels 17 and 1.9., the arrangement being such that when the clutch mem bers are engaged the chain wheel 19 drives that 17 and when thrown out of commission the chain wheel 19 runs idly on the counter shaft and the chain wheel. 17 remains stationary. A pivoted controlling lever 21 is associated with the clutch member 20 and to the lever we connect an operating rod 21 which in actual practice will pass over toward the operators seat on the binding machine so that the operator on the binding machine can engage or disengage the clutch members.

We have not considered it necessary to enter into a detailed description of the clutch used as such is a common commodity and any device that will function to drive the gear wheel 17 at will, will serve our purose.

Forwardly, the side members 1 and 2 of the frame are provided with similar opposing elevated bearings 22 and 22 which carry rotatably a cross shaft 23 having upstanding crank ends 23 fitted at their extremities with rollers 23*. These rollers are adapted to engage with similar cams 251- and 2st permanently secured to the ends of the shaft 15. The shaft 23 carries a plurality of similar spaced rearwardly extending, downwardly curving fingers or prongs which in the normal or sheaf receiving position of the basket later described are just nicely clear of the ground, being held in such position by the cams 24: and 2%. Here it will be observed that the cams present vertically extending faces 24* against which the rollers are initially engaged with the result that as soon as the shaft 15 starts to rotate the said cams operate on the rollers to quickly raise the rear ends of the prongs. After the prongs have been raised the required distance the rollers run on to the curved faces of the cams which permits the said prongs to gradually lower.

The elevated rear ends 1.3 on the arms 11 and 12 carry a cross shaft 26 which pivotally supports a butter 27 such being, in the pres ent instance, in the form of a downwardly extending sheet metal plate, the lower edge of which is approximately in the plane of the machine frame. The lower end of the butter is engaged by a push bar 28 which has the forward end hooked over the shaft 15 and provided with a forwardly extending lug 28'.

A coiled spring 29 is provided, the spring having the lower end attached to the cross ember 3 of the frame and the upper ends extended in the form of a threaded rod which passes through the lug and is pro vided with an adjusting nut 2 By adjusting the nut one can cause the butter plate to take an advanced or withdrawn position as obviously when the nut is tightened up or loosened the bar 28 will be rotated on the shaft 15. In this connection it is pointed out that the arrangement just described causes a pressure to be exerted against the lower end, of the butter plate when the same is forced ahead by the shock. The pressure is determined by the adjustment of the nut 29.

To the outer sides of the bearings l and 1% we pivotally mount the forward ends of a pair of similar equal lengthened, rearwardly extending, swinging arms 30 and 31, the rear ends of the arms terminating in a position more or less centrally above the tracks in bearing sleeves 30 and 31 which receive rotatably similar horizontally disposed, axially aligned short shafts 32 and 33. The outer ends of these latter shafts are provided with similar chain wheels and 35 which are connected by means of chains 3d and 35 to chain wheels 36 and 36 secured permanently to the shaft 15, the arrangement being such that when the shaft 15 rotates the shafts 32 and 33 are simulta neously rotated. The outer ends of the shafts 32 and 33 also carry similar cams 37 and 37, the cams being fixed to the shafts to rotate therewith and being also designed to operate on the tracks 5 and 6. Obviously the cams support the rear ends of the swinging arms from the frame and will cause the said rear ends of the arms to simultaneously move up and down when the shafts and 33 are rotated.

The cams are of a peculiar triangular shape, shown in the various figures, and each presents two comparatively long converging faces 38 and 39 which meet at an acute angle, the arrangement being such that in the rotation of the shafts and the said shafts will be initially quickly elevated and subsequently quickly dropped, such being obvious by observing Figures 1, 5 and 6 wherein the cams are shown in different positions. The cams are provided with rollers 40 which ride the track and here it will be observed that there are several rollers at the wide ends of the cams, this being arranged so that after the shafts 32 and 33 have returned to their lower position as shown in Fig. 6, the latter rollers will ride the track and carry the cam and gradually raise and then lower the shafts 32 and 33 before coming to the initial position as shown in Fig. 1. It will also be observed that the cams are positioned eccentric on the shafts, the shafts being nearer the faces 39 than the faces 38. On this account the shafts 32 and 33 are elevated higher above the frame when in the position shown in Fig. 1 than they are when in the position shown in Fig. 6. The object of this will be later explained.

The inner ends of the shafts 32 and 33 carry the sheaf receiving and shock forming basket indicated generally by the reference numeral 41. Said basket comprises a body part 42 having an open top and bottom and a pair of gates (right and left) 43 and 44 which are hinged to the side of the body part at 45 and which when closed and in the sheaf receiving position of the basket support the sheaves placed in the basket through the open top thereof, and during the time that the shock is being built.

In Figures 1, 2 and 4 the basket is shown in sheaf receiving position, the gates being closed and here it will be observed that the top and front end of the basket are open, that the rear end and bottom thereof are closed and that the said basket is coned shaped, the axis of the cone being normally inclined and being indicated by the dotted line a-a. The butter 27 has a position in advance of the open front end of the basket and the fingers 25 normally underlie the gates. The gates are normally held closed by a knuckle joint at each side which is broken automatically and at the proper time to permit the gates to simultaneously open.

Each knuckle joint comprises an L-shaped bar 46 pivotally secured at 46 to the basket body in a location adjoining the basket supporting shaft and having one end provided with a weight 47 and the other end connected pivotally to a link 48 which is attached pivotally to an outstanding lug 49 formed at the end of a reinforcing bar 50 secured to the gate. The weighted end of the arm is normally supported by a catch 51 secured to the basket body.

The arrangement is such that when the parts are in position as shown in Fig. 7, the gates are locked closed by the closed knuckle joints formed between the links 48 and the short ends of the bars 46. Upon the basket being turned forwardly in a clockwise direction, however, it will be apparent that when the weights come to a vertical position they will .fall ahead and break the knuckle joints and in so doing permit the gates to simultaneously open. If for any reason the gates should not open under this action, we have provided a safety attachment which will positively cause them to open, such embodying a bell crank 52 secured pivotally to each side of the basket body and having one end connected by a link 53 to the knuckle joint. The free end of each bell crank is adapted, in the forward rotation of the basket, to strike an inwardly extending pin 54 carried by the lower end of a link 55 located at each side of the basket and having the upper end thereof pivotally connected at 56 to a lug provided at the under side of each of the bearings 30 and 31. The links 55 are connected with parts later disclosed.

As their lateral or swinging movement is relatively small, the pins 54 are always maintained in the path of the moving bell cranks so that the bell cranks will strike said pins and positively cause the knuckle joints to be released if such is not previously accomplished by the action of the weighted arms 46.

The upper part of the basket is fitted with side rods 57 and 58 which extend rearwardly and form guides for slide sleeves 59. These sliding sleeves carry a yoke shaped pressure bar 59 which normally crosses the rear part of the open top of the basket. This pressure bar 59 is adapted, in the turning of the basket, to slide initially ahead to grip and hold the butt of the formed shock and subsequently to return to its initial position as shown in Fig. 1.

The body part of the basket is reinforced by an angle bar 60.

Guide pulleys 61 are secured to the arms 30 and 31 to carry the under sides of the chains 34 and 35.

In order to cushion the basket as it drops we have provided cushioning springs which operate in conjunction with other parts now described.

The cushioning springs 62 and 62 have their forward ends adjustably connected to the forward end of the frame and th"ir rear ends connected to similar bell cranks 63 located one on each side of the frame and pivotally attached at 64 to the side arms 1 and 2 of the frame. The said bell cranks each present an upwardly extending, comparatively short arm attached to the spring and a rearwardly extending comparatively long arm which is attached by means of the pivot pins 54 hereinbefore referred to, to the lowqr ends of the links 55. The tension in the springs can be adjusted as desired. and there is a small amount of tension in the springs when the basket is in the sheaf receiving position as shown in Fig. 1.

When the basket is coming to shock releasing position as shown in Fig. 6 the springs 62 and 62 are extended to cushion the dropping basket and here it is to be ob served that the rearwardly extending ends of the bell cranks 63 are pushed down by the links 55, in such position of the basket, owing to the fact that the pivot shafts and 33 of the basket are nearer the tracks than when the basket is in the sheaf receiving position as shown in Fig. 1.

This is brought about by the eccentric mounting of the cams hereinbefore referred to. During the major part of the dumping movement of the basket the tension in the cushioning springs becomes less and the in-- creased tension is not brought about until the basket is reaching the final dumped position.

In order that the operation of the shocking machine may be better understood we will now describe the manner in which it operat s, assuming that the parts are initially in the position shown in Fig. 1, that the clutch is out of commission and that the shock is being built in the basket by the sheaves dropped into the same through the open top thereof, with the butts of the sheaves disposed towards the butter. Upon the attendant considering that a sufficient number of sheaves have been placed in the basket to form a .shock, he pushes the rod 21 to engage the clutch members 20 and 20 which causes the wheel 8 to drive the shaft 15 through the gearing that is provided. As the shaft 15 rotates it drives the chains 34 and 35 and consequently causes the basket to rotate in the direction indicated by the applied arrow Fi 1. As the basket is. rotated the cams 87 and 37 cause the same to quickly rise and during the rotating of the basket the butter plate is pressing against the butts of the sheaves and forcing the heads thereof into the small end of the basket. This operation effects the shaping of the shock, the heads being drawn together. As soon as the guide rods 5'7 and 58 have been turned far enough the sleeves 59' start to slide forwardly of the basket and as the basket rotates they come to a position as best shown in Fig. 5 where the yoke shaped. bar 59 is holding the butts of the sheaves over against the bottom of the basket and is serving also to prevent the premature escape of the shock. During all. the turning movement of the basket it is of course to be understood that the machine is advancing.

In the initial turning of the basket, the cams 2- and 24 operate to swing the pron gs up from the position shown in Fig. l to the position shown in Fig. 5 where it will be observed they engage with the butt of the shock. The said prongs are r tained in this elevated position for a period of time during which the basket is turning, and accordingly the prongs have a tendency to spread the butt as one corner, so to speak, of the butt of the shock is at this time engaged with the ground with the result that the pron-gs, in

the rotation of the basket, tend to pull the upper part of the shock butt away from the anchored or ground contacting part. This action spreads the butt and is occurring approximately in the position of the basket as shown in Fig. 5, it being borne in mind that the machine is moving ahead, and the basket is turning. As the basket continues to turn from the position shown in Fig. 5 to that shown in Fig. 6 it drops quickly towards the ground, and the weight; of the dropping bask t acts to firmly plant the butt of the shock on the ground and also to cap the shock by forcing the heads of the sheaves into the small end of the basket. Coincident with the time the basket is brought "to this shock planting position the weighted arms are adapted to swing ahead and undo the knuckle joints with the result that the gates open rearward-1y as shown in Fig. 6 and permit the advancing machine to leave a well shaped shock firmly planted on the ground. As the has Qt completes the revolution it rises slightly, to raise the then front part of the basket from the deposited shock, the gates close under the action of gravity and become locked by the knuckle joints which are closed by the movement of the weighted levers, the yoke bar 59 returns to its original position and the cams 24c and 24c re-set the prongs with the result that when the revolution is completed all parts are reset and the attendant has accordingly only to disengage the clutch members at the proper time when he can start building a further shock in the basket.
