Specification of Letters Patent.

Patented July 17, 1917.

Application iled May 17, 1915. Serial No. 28,651.

To allwlwm t may concern:

Be it known that l, WILLIAM RICHARDSON, a subject ofthe King of Great Britain, and resident of the village of Tyvan, Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Sheaf-Loading Machines, of which the following is the specification.

This invention relates to improvements in sheaf loading machines and particularly refers to that type of machine whereby the mechanical loading of sheaves of grain and the like is effected, and the objects of the invention are to more expediently and effectively perform such loading, to render the operation more simple and less expensive and to effect a saving in labor and time and other objects which will be made clear hereafter, and it consists essentially of the improved mechanism fully set forth and described in the fo-llowing specification and accompanying drawings forming part of the same.

In the drawings,

Figure 1 is a plan view of the complete loading machine.

Fig. 2 is a side elevation of part of the machine.

Fig. 3 is arfragmentary elevation of the opposite -side of the machine, t

Fig. i is an end elevation of the machine.

Fig. 5 is an end elevation of the pick-up.

Fig. 6 is a fragmentary side elevation, with the cover removed, of the sprocket wheel showing the ratchet wheel mounted on the pick-up shaft.

Fig. 7 is a sectional elevation of the same.

Fig. 8 is an end elevation of the chain flexure and guide sprocket wheels.

Fig. 9 is a plan view of the same.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the complete machine consisting of the pickup mechanism B, the transverse conveyer C disposed at right angles to the pick-up and the longitudinal conveyer D disposed at Y right angles to the rstV said conveyer.

The conveyer C is mounted onV a frame J carried by the frame E constructed of longitudinal channel iron members l having the transverse members 2 and 5 suitably attached thereto by -any convenient means,

such as angle iron joints bolted or riveted to the said members.` One end of this frame is supported bya wheel 6 rotatably mounted on the fixed shaft 7, the inner end of which is carried by the transverse member 2, the outer end being mounted in the guard frame 8 attached to the said transverse member and designed to protect the wheel.

The end of the frame E remote from the member 2 is provided with a driving wheel 9 located between the transverse members 4l and 5 and rotatably mounted on the shaft 10 rigidly fixed by any suitable means in the bearings 11 and 12 carried by the said transverse members, the said shaft further carrying the rotatable sprocket 18 and pinion wheel 14 rigidly xed to the hub of the wheel 9 and located between the same .and the transverse member 4.

The frame J is supported by the frame E which is braced or strengthened in any suit-` able manner, the first said frame being pron vided with a drum 15 located at the. end adjacent to the wheel 6 and carried by the spindle 16 rotatably mounted in the adjust able bearings 17, which make threaded en gagement with the screws 18 carried by the brackets 19, the said spindle being further provided with sprocket wheels 20 rigidly fiXed near the ends thereof.

A second drum 21 is carried by a spindle provided lwith sprockets 22 and rotatably supported in bearings 23 carried by that end of the frame J located above and overhanging the lower end of theconveyer D. An endless belt 24 or the like extends between and takes around the drums 15 and 21 and is designed to be driven by a suitable mechanism hereinafter described.

The frame J carrying the conveyer C is reinforced or stifl'ened in any suitable manner.

The chains 25 taking around the sprocket wheels 20 and 22 are given the necessary fleXure and direction of drive by engaging intermediate of their length with the guide sprocket wheels 26 and 27, the former of which is rigidly mounted on the spindle 28 rotatably carried by the bracket 29, the lat* ter being rigidly mounted on the shaft 30 rotatably mounted in the said bracket.

Motion isV transmitted through the shaft 30 to the sprocket 31, such motion being 'in at an angle of about 40O to the ground plane,

the inner ends being Vmounted on a frame 35 and disposed at a slight angle to the ground plane as shown in Fig. 2.

r1`his frame is braced or strengthened in any Vsuitable manner, the top end of the frame being provided with a. drum 36 car ried by the spindle 3-7 which is rotatably mounted in the bearings 38 and provided with sprocket wheels 39 rigidly mounted near the ends thereof.

Aosecond drum 40 is located at the opposite end of the frame and mounted on the spindlek 41 carrying sprocket wheels 42 rigidly mounted near the ends thereof, such spindle beingrotatably supported in the adjustable bearings 43 making threaded engagementwith the screws 44 carried by the brackets 45 from the said frame'. An endlessbelt extends between the drums 36 and 40 and takes therearound.

f The :chains 45' taking around the sprocket wheels 39 and42 are given the desired flexure and direction of drive by engaging intermediate of their length withthe sprocket wheels 47 and 48, the former of which is rigidly secured to the spindle 49 rotatably mounted in the bracket 50, the latter being rigidly mounted to the shaft 51 rotatably mounted in the said bracket. The shaft 51 carriesv a-pinion 5 2' meshing' with the pinion 53,( onlv the spindle 49 and is further provided with a sprocket wheel 54 through the medium of which motion is transmitted to theshaift.

y1`he sprocket wheels 47 are designed to rotate in a direction opposite to that of the shaft 51 v,thereby assisting in driving the chains 46 and at the saine time keep them in a state of tension.v Y

The pickup mechanism IB consists of two end disks 55 rigid-lyV fixed on' the shaft 56 which is mounted in the bearings 57 carried by the brackets 58 designed to support the pick-up B from the frame E, the outer end of the shaft 56 being s provided with sprocket wheel 59 loosely mounted thereon, but adapted to impart rotary motion tothe said' shaft in the following manner The sprocket wheel 59 is cast hollow and has .a ratchet wheel -`60" located therein rigidly keyed tev the shaft 56:"A and designed to engage with the spring controlled pawl or detent 61 pivetally intimated Joa the inner face of the sprocket wheel in sucha manner' that when the' pawl and ratchet wheel are in engagement any rotation of the sprocket is 65 intermediate of their length, the outerl ends of the said rods or shafts having pinions 66 secured thereon.

Rotatably mounted on the disks 55 are idler wheels 6'7 which intermesh with the pinions 66 and the rack 63 from which the idlers derive their motion to drive the pinions 66 carried by the shaft 64.

Motion is transmitted t0 rthe several parts through the driving wheel 9 rotating on the shaft 10 and simultaneously rotating the sprocket wheel 13 and pinion 14. The sprocket wheel 13 is connected by a chain 68 to the sprocket wheel 69 carried by the shaft 70 which is further provided on one end with a sprocket wheel 71 adapted through the medium of the chain 72 taking around the sprocket wheel 54 to rotate the shaft 51, thereby rotating the sprocket wheels 47 and 48 so driving the chains 46 and transmitting motion to the conveyer D.

The pick-up B is driven from the pinion 14 meshing with the pinion' 73 which in turn rotates the shaft 74 and the sprocket wheel 75 (Fig. 1) fixed to the end thereof, whence the rotation is given to the piclcup through the sprocket 59 and an internal mechanism by means of the chain 76 taking around the said sprocket wheels.

The conveyor C is also driven from the pinion 14 through the pinion 77 mounted on the shaft 78 carrying the beveled pinion 79 intermeshing with the beveled pinionl 80 rotatably mounted in the shaft 81 which is further provided with a sprocket wheel 82 adapted to transmit rotary motion to the sprocket wheel 31 mounted on the shaft 30 by means of the chain 83. The shaft 30 gives the necessary rotation to the sprockets 26 and 27 which in turn drive the chains 25.

1t may be found desirable to throw the conveyer C out of gear and to this end the lever 84 pivotally mounted in the tongue H may be operated and the motion of the lever transmitted through the link 85, bell crank 86 and pivoted lever 87 to a clutch 88 coacting withthe beveled pinion 8O which when disengaged from the said clutch is free to rotate, thereby permitting the conveyer to come to rest.

To render the pick-up B inoperative, a similar type of mechanism is used, the desired motion being obtained from the lever 89 pivotally mounted on the tongue H and designed to operate the link 90, bell crank 91 and pivoted lever 92 whereby the clutch 93 coacting with the sprocket wheel 75 is disengaged therefrom, permitting the sprocket to come to rest.

The conveyer D is also capable of being thrown out of gear by a mechanism similar to that already described with reference to the conveyer C and the pick-up B and con sists of the lever 94 pivoted on the tongue H and designed to operate the link 95, the bell crank 96 and pivoted lever 97 which. actuate the clutch 98 coacting with the sprocket wheel 69, disengaging the same and allowing the said sprocket to freely revolve on the shaft 70 which under such conditions becomes stationary.

The tongue H extends rearwardly and is pivotally attached at its near end to the frame E by means of the pin 99, the outer end of the tongue being supported by means of a ground wheel 100 pivotally mounted on the lower bifurcated end of the swivel pin 101 projecting through the tongue.

To render the action of the wheel 100 more even, a spiral spring 102 extends around the outer periphery of the swivel pin 100 and is located between the lower bifurcated end of the pin and the said tongue. This swivel pin is further provided with a drivers seat 103 of suitable construction located adjacent to the levers 84, 89 and 94 which will be convenient to the hand of the driver'.

Due to the rough surface or any other cause, it may be found desirable to tilt thc machine A and to this end the lever 104 is pivotally connected to the tongue H and provided with a detent cooperating with the quadrant 105, the said lever being pivotally connected to one end of the link 106, the other end of which pivotally engages the pivotally mounted crank arm 107 which in turn is connected through the link 108 to the bracket 109 carried by the frame E.

Having described my invention I will now show the manner in which it is operated:

The machine A is drawn by a team of horses or by any suitable motive power, the

hook 110 of the telescopic rod 111 being attached to a hay rack, the top of the conveyer engaging with the same. The wheels 9, 6 and 100 engage with the ground, the machine being guided and controlled by the driver actuating the levers 84, 89, 94 and 104 located adjacent to the drivers seat.

The wheel 6 is only used as a means of support, the train of mechanism driving the several parts of the machine A being operated from the wheel 9, the function of which is as follows:

To prevent any sheaves of grain not directly in line with the pick-up during the operation of the same from fouling with the gearing attached to such pick-up, aguard .frame 112 is located on each side of the pick-up and disposed outwardly toward the top so overhanging the gearing attached to the said pick-up.

The forks 65 in revolving lift the sheaves of grain or the like which it is desired to load and deposit them on the conveyer C which in turn carries the said grain to the conveyer D from whence they are delivered to the hay rack.

Since the inner end of the conveyer C carried' by the drum 2l is located above the frame E and above the inner end of the conveyer D carried by the drum 40 the grain in leaving the conveyer C will be thrown well onto the conveyer D.

What I claim as my invention is:

1. In a sheaf loader, a pick up, disks carried at each end thereof, gears on said disks` for' operating said pick up, and a concave guard polygonal in outline curved over said disks to protect said gears.

2. In a sheaf loader, a pick up, diskscarried at each end thereof, gears on said disks for operating said pick up, and a concave open frame polygonal in outline, and internal bracing rods in said frame, said frame being curved over said disks to protect saidY gears.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
