PATENT OFFICE MOOSE J'AW, SASKATCHEWAN, CANADA SHOCK LOADING AND UNLOAD'ING-.MACHINE Application led February 17, 1927, Serial No. 169,093, and in Canada February 24, 1927.

My invention relates to a new and useful shock loading and unloading machine, and aims to produce a machine of that nature which is automatic in action and does the Work rapidly and effectively.

One object of my invention is to producea machine capable of gathering the shocks from the field,'when they may be transported to the threshing machine and there unloaded automatically.

A further object ofmy invention is to so construct a machine as to economize the cost of threshing, enabling one operator to operate the same and dispense with a good proportion of the labor now required to supply threshing machines effectively, and increasing the daily output of the thresher to a great extent.

In all these figures, similar reference symbols refer to same parts.

In the drawings, referring especially to Figures 2 and 3, 1 is the main frame or chassis supporting practically all the -live parts. This frame comprises two side pieces 2 and 3, united by a cross bar 4 having suitable bracing brackets 5. Across the chassis is mounted two bars 6 and 7, serving the double. purpose of binding the sides 2 and 3 as wellas a means to hinge a second frame or chassis 8. having side members 9 and 10 united by cross beams l1 and 12. The front of this chassis is converging, as shown, and in this converging part are two cross bars 13 and 14, serving to support bearing blocks l5. Another cross bar 16 is positioned at the front of the conical shapev parallel with the end 17 of the frame. These two bars also support bearing blocks 18. The frame 8 is hingedly connected to the chassis 1 by means of pins 19 and 20 passing through the center of bars 7 and 6. This connection is to enable the chassis to have a rocking movement independent of frame 8 so that the machine may accommodate itself to the irregularities of the ground. The rear of the chassis 8 is supported on wheels -94 mounted on aXles 95 provided with steering connections of the usual well-known form, actuated from the .drivers seat by means of an upright rod 96 mounted in bearings 97 on the sides of tank 52 and having a'crank 98 connected to a rod 99 and by suitable connections to a steering wheel 100. Chassis 1 is provided with traction wheels 21 having internal gears on their rims. They are mounted on the sides 2 and 3 by suitable axles 22, here shown provided with roller bearings 23.

In order to mount the motor on frame 1, longitudinal bars 24 are fastened to cross bars 6 and 7. The motor 25 is suitably bolted to these bars and the same may be of any known model. In the present instance, the forward end of the'motorA shaft is provided with a Cil sprocket 26, also with a friction wheel 27 mounted to slide on the projecting end of said shaft. The rear part of the engine isv provided with the usual clutch and transmission gears. The differential gear 28 is mounted back of the transmission. The driving shaft 2,9 is provided with spur driving pinions 30 engaging the internal gear 31 of the driving wheels.

The frame 1 is provided at its front end with a shock gatherer comprising a travelling pick-up composed of sprocket chains 32,-in the present instance four are shown. Thesey chains are mounted on sprocket wheels 33 and 34 supported on shafts 33a and 34a. 34a is mounted in bearings 37 positionedon chassis 1. The shaft 33a is mounted in bearings on the sides 38 of the'pick-up frame. The 34 are provided with rods 39' sprocket wheels for a purpose hereinafter described. The

sides 38 of the pick-up frame are provided with cross bars 42 to which are fastened an .upper guide plate 40 and a lower guide plate 41. Plate 40 has its ends turned downwards as shown and plate 41 has its rear end turned upwards, as shown at 43. Power for the pick-up is derived from the motor through friction wheel 27 and friction disk 44, the latter being slidably mounted on' a shaft 45 mounted in bearings 46 supported on the sides 2 and 3 of the frame 1. A sprocket wheel 47 is mounted on the outer end ofv shaft and carries a sprocket chain 48 engaging a sprocket 49 mounted on shafts 34a.

To operate the pick-up frame from the drivers seat and to impart to the same a variable speed, the following arrangement is used: The friction wheel 27 is moved radially on disk 44 by a rod 112 having one end bent at right angle and fork shaped to engage a groove 113 in wheel 27. The other end of rod 112 is also bent to form a connecting pin mounted in a bearing of a rocker arm 114 which is mounted on-a shaft 115, which in turn is mounted in bearings on'the bars 24. Shaft 115 also carries a rocking arm 116 to which is connected a rod 117 connected to a hand lever 118.

To release or engage the friction disk 44 by imparting a sliding movement on shaft 45, the shaft is grooved at 119 to receive a key 120. The disk 44 is grooved to slide on the key 120, it being fitted to slide easily along the same. To effect the sliding movement, a groove 121 is madeia-t the back of disk 44. Into this groove a forked rod 122-engages. This rod is bent Vat right angles, as shown, and mounted into a bearing lock 123. The free end of rod 122 carries pins 124 somewhat distanced from one another, between which a head 126 travels. This head is mounted at an angle to the forked rod 122 and is connected to a bar 125 mounted in bearing 127 on the cross bar 6. From this bearing the bar 123 leads to an upright bar Shaft 4so as to receive an ear 50b 128, to which it ,is pivoted at 129. Bar 128 is fulcrumed at 130 and the end is shaped to form a handpiece 131 accessible to the driver.

It is necessary in order to properly position the pick-up forks 36 that means be provided to present their active ends on the shocks when gathering the same and disengage said shocks when they have been carried at the other end of the pick-up. For that purpose, the polygonal drum has been provided. The fork itself comprises a pair of prongs 36 curved as shown, each having a flange to reinforce :the same and serving as a bearing for attachment to the chains 32in the following manner: through the bearings in flanges 50, a rod 50a is passed. This rod is slotted at each end integral with a special chain link 50c in chain 32. The rod 50 is fastened to ear 50b by a rivet 50d. The rear portion 51 of each fork has an extension 110 at right angle thereto extending suiieiently to overlap the corresponding extension of the adjacent fork medially between the chains, the two aforesaid extensions being riveted together as at 111, see Figure. 5. This rear" portion 51 of the fork is intended to guide the same in the following manner: When the pick-up is placed in motion, the forks will travel with their guiding ends 51 resting against the plates 40 and 41. In the Uli position shown in Figure 4, one set of forks 36 have their rear ends 51 resting against one side of the hexagon drum between sprockets 33. This will cause the same to remain in extended position so as to pick up the shock and carry it over the sprocket without change of position. The fork is then keptin the same position by plate 40 until it reaches sprocket 34 and having lost its support, it will swing backward and free the shock, which will be taken up by the elevator hereinafter described. Rods 39 in sprockets 34 serve to limit the backward swing of the forks until they reach plate 41, when they will be turned forward by the same, the ends 51 sliding against the plate 41 until one of the sides of the hexagon drum 35 is reached.

It is necessary to provide means to regulate the speed of the pick-up and for that purpose, the friction wheel 27. slidingly mounted on the engine shaft in connection with friction disk 44, when actuated by suitable levers heretofore described, will serve the purpose. 5

It is further necessary that means be provided to raise the pick-up out of action when not in use. For that purpose, I provide at the front of the pick-up frame a bracket 101, bolted to the end thereof and having an eve 102 into which a. cable is attached. The side 3 of the main frame is provided at its front end with a pulley 103 upon which the cable passes, the same being connected to a lever 104 pivoted at 105 on the frame 3, the cable being connected at 106 on said lever. The end is .shaped to receive one end of a draw-rod 107. the other end of which is connected to the end 108 of a hand lever 109 positioned adjacent the drivers seat. Such means enables thepperator to raise or lower the pickup by actuation of lever 109.

As above stated, to frame 1 is hingedlv connected frame 8. This frame is intended to support a gathering body which, in the present instance, is show-n as a large tank 52 having an open top, the side walls of which diverge from the front. Upon the floor is mounted carriers 53 and 54. These carriers are composed of cross bars 55 and chains 70 (see Figure 7). The bars are preferably :made of angle iron and provided with casters 56 in order to enable them to travel over the fioor 57 of the gathering tank. In the gathering tank is mounted an end gate 58, shown in Figure 10, composed of aframe formed of angle iron having a horizontal section 59 and braces 60. The vertical side 61 extends to the top of the gathering tank and is there provided with antifriction wheels 62 mounted on a cross bar 63 bolted at 64 to the sides 61 (see Figure 9). These antifriction wheels 62 are loosely mounted on rod 63 so as to move sideways to follow the diverging rails. Cotter pins 65 are provided to maintain them on the cross har. Vheels 62 travel on V-shaped rails 66 fastened to the tank and having their rear ends turned upward as at 67 for the purpose hereinafter described. The carriers 53 and 54 are mounted on sprockets 68 and 69, upon which sprocket chains 70 are mounted. These chains are united by bars 55, as shown in Figure 7. Carriers 53 and 54 are actuated by means of a shaft 71a in casing 71, mounted in the sides 9 and 10 of frame 8. Each end of said shaft is provided with a `sprocket wheel 74 on which is mounted a sprocket chain 72, extended to a second sprocket 73 mounted on a shaft 75 also in bearings on sides 9 and 10. Shaft 71a is actuated by a worm gear mounted thereonand a worm 76 carried by a drive shaft 77, connected to a reverse gear 78 by means of a uni- It will be understood that the carriers 53 and 54 are moved intermittently in order to permit the tank to be completely filled. Vhcn the elevator 8O has carried a quantity of shocks sufficient to fill the adjacent section of the tank where they fall, the operator, by means of foot pedal 89, through rod 90 connected to pin 91, crank 92, link 93, which in turn is connected to the shaft of reverse gear 78, causes the travelling carriers 53 and 54 to carry the shocks a distance towards the rear of tank 52. The elevator then fills the new empty space and so on until the tank is loaded, when the load is ready to be transported to the threshing machine.

In order to lconvey the shocks from the 65 pick-up to the gathering tank 52, an elevator 80 is provided. The construction of this elevator is shown in detail in Figure 6. It cornprises side pieces 81 having Haring guide boards 82 and provided with shafts 83 and 84 respectively at each end thereof. shaft 83 carrying sprocket wheels 85. Shaft 84 is provided With similar sprocket Wheels, not shown. Upon. these sprocket wheels travel sprocket chains 87 carrying cross bars 88, constructed as shown in Figure 7 but dei void of casters 56. This travelling apron forms an elevator to convey the shocks from where they leave the pick-up into the tank 52, where they fall on the floor of the tank between the cross bars of the chain carriers 53 and 54.

The power to drive apron 80 is taken from shaft 45 by means of a sprocket 45a on which is mounted a sprocket chain 132, leading to a second sprocket 132a mounted on a shaft 134 in bearings on sides 81. Shaft 134 carries a second sprocket 133, not shown, on which is mounted a driving chain 135 engaging a drivingr sprocket wheel 86" on the end of shaft 84.

In order to unload the contents, the carriers 53 and 54 are moved rearwardly and the pressure of the shocks on the end gate 58 will cause the same to swing rearwardly, the

wheel 62 engaging in the bent portion 67,

which acts as a bearing. The shocks will then fall between the apron and the hori- `zontal portion 59 of the gate. When the contents of the tank have been fully unloaded, the travelling gate 58 must. be returned to the front thereof. To effect this return, means is provided accessible to the driver for actuating reversing gear 78. This means comprises a. hand lever 136 pivoted on the frame of the drivers iioor 137. A bar 138 is fulcrumed on lever 136 and leads to pedal 89 where it is pivoted. By drawing this lever backward, pedal 89 will raise and cause rod 90, which is connected to crank 91, to throw the reverse gear backwards, when the travelling carriers 53 and 54 will move towards the front of the tank, carrying with it the end gate 58 until the outer end of the horizontal side 59 reaches thel forward end of the tank.

The mode of operation is as follows: The pick-up having been raised from the ground, as previously explained, the driver, by means of' foot pedal 139, drives the machine to the field, when the pick-up is lowered by the mechanism previously described, and the 'shocks are carried over the same onto the movement of the carriers 53 and 54, thereby causing the gate 58, which as soon as free from shocks returns over the carriers by gravity, to travel towards the front of the tank until the en d of its horizontal floor 59 reaches the front side of the said tank` when the machine is again, ready to start for another load.

The mechanism herein described and illustrated represents one practical form of my shock loa-der but it should be understood that minor changes both in the location of the parts as well as the shape and disposition of the .same may be made without departing from the spirit of my invention as covered by the following claims:
