GEARING FOR AUTOBINDERS.

Specification of Letters Patent. Patented Sept, 19, 1916,

Application filed December 26, 1911. Serial No. 667,724.

' To all whom t ymay concern Be it known that I, VACLAV M. HoRACnK, a citizen of the United States, and a resident of Tabor, in the county of Bonhomme and State of South Dakota, have invented certain new and useful Improvements in Gearing for Autobinders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements of farm implements propelled b y means of a motor and comprises a tractor carrying a self binder, the motor, however, being detachably secured to the binder.

The primary object of my invention is to provide an auto self binder, the operating mechanism of which is driven by the power of the tractor'.

Another object is to provide an autobinder so constructed that the operator may control the motor and the tractor, while controlling the mechanisms of the self binder.

A still further object is to provide a self binderwith a power driven pulley to which a belt may be connected -to drive'certain auxiliary machinery, such as a corn sheller, elevator and the like.

Another object of my invention is to provide a self binder having a propelling mechanism provided with -a steering. wheel, and a foot operated mechanism controlling the grain wheel of the binder.

A still further object is to provide an auto-binder with a transportation truck detachably secured to the machine and ar ranged to be driven by the driving motor.

lVith these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of'this specification and in which like characters of reference indicate similar parts in the several views: Figure 1 shows a top view of an auto-binder embodying my invention, with the elevator detached. Fig.

2 shows a rear end view with parts broken away, showing the elevator and part of the chute. Fig. 3 shows an enlarged detached same can be used while the binder is out of service. y

In the drawings A designates al suitable reaper, B the elevator as shown in Fig. 2, and C the chute. The reaper and binder are of any approved construction.

In the drawings the main frame 3 is shown as giving support'to the bull wheel 2, while secured to the outer end of the reaper A is the grain wheel l.

Extending from the carrying frame and detachably secured to the frame portion 52 shown in Fig. 1 is the tongue 4G which is secured by means of the brace 53 and this tongue 46 as shown in Fig. 5, at its forward end, carries the bearing head 54. Revoluloly held within this head 54 is the stem of the I caster fork 48 giving support to the caster wheel 55. Fixed to the stem of the fork 48 is the bevel gear 5G. The machine is guided by means of this caster wheel 55, though by means of the grain wheel 1, the machine can also be guided within certain limits, as will be described more fully hereinafter.

Held to the transverse frame members a, is a platform 19 carrying the motor M.

This motor has the driving shaft c, which is operated by means of the starting crank 45 as is usual in gasolene motor construction. The motor M drives the fly wheel 57 having the friction clutch 50, the movable member 5S of which is actuated by means of the striding clutch arm 49, pivoted to the bracket G0 as shown in Fig. 1. Extending from this clutch arm 49 is the connecting rod 18, which is led to a clutch lever 17. This lever is pivotally held to a suitably notched sectoi` 16 secured to the main frame as shown 1n Fig. 2. The movable member 58 is splined to the main driving shaft 0, and is brought into engagement with the friction clutch 50,

when it is desired to rotate the driving shaft c. This driving shaft at its end is provided with the worm 22, working in connec` tion with the worm gear 21, this Worm gear being secured to the main shaft 32. As shown in Fig. 2, this main shaft 32 is held within the bearing 2O and 33, and at one end has secured to it the bevel pinion 31, meshing with the clutch gear 9 shown in Fig. l. This gear' 9 is securely held to the driven shaft l0, and is arranged for co-action with the clutch chain gear 43. The chain gear 43, as shown in Fig. 1, is operated by means of the controlling lever 38 which is connected to the notched bar 65, by means of an ordinary spring actuated detent in a manner insuring the lever 38 being adj ustably held.

ther parts of the harvester (not shown) may be operated by a chain 44 which passes around the wheel 43. l

As shown in Fig. l the driven shaft 10 carries the bevel pinion 42 meshing with the drive gear 4l secured to the shaft 68 of the transmission gearing. In the drawings the housing surrounding the transmission gearing is marked T, which transmission gearing is controlled by a lever 35, suitably fulcrumed upon the carrying frame and equipped with the usual sector-engaging detent, said lever being linked as at 34 to a shifting lever of said transmission gearing, all as clearly disclosed in Fig. 2. This transmission gearing is adapted to be manipulated by a lever 35 and link 34 in any suitable manner. This transmission gearing is carried upon suitable brackets extending from the carriage and at its end works within one of the members a. The transmission shaft 68', forms a continuation of the shaft 68, as shown in Fig. 1, and at its inner end carries the chain sprocket 40, and passing over this sprocket is the chain 69 also passing over the chain gear 70 secured to the bull wheel 2.

From the foregoing description it will be noticed that driven shaft 1() is in gear connection with the main shaft 32, which in turn, is in worm gear connection with the driving shaft c.

At its forward end the shaft 10 carries the disk 70 to which is suitably secured the pitman 11, driving the sickle.

As shown in Fig. 2 the main shaft 32 also carries the chain gear 72 over which passes the chain 73, at its upper end working over the chain gear 74. This gear 74 is held upon a shaft 75, carried within the bearing 14, suitably secured to the elevator frame B and also connected to the frame post 5. l At its outer end this stub shaft 75, carries the driving pulley 5 shown in Fig. 3 and working from this pulley 5 is the driving belt 6 which also passes over` the driven ratchet faced pulley 7 working upon the rear shaft 12.

As shown in Fig. 2, the pulley 7 is provided with a grooved hub 25, having a ratchet face arranged for co-action with the ratchet collar 8', fixed to the rear shaft 12. To operate the shaft l2 it is necessary to bring the members S and 25 into contact.

This is accomplished by means of the lever 9', the lower forked end of which is held within the groove of the hub 25. The lever 9 is held in adjustable position by means of a suitable detent engaging within the notches of the sector 24.

As shown in Fig. 3, I employ a suitable foot lever 26 having a grooved shive 28 working in conjunction with the loose belt 6 passing over the pulleys 5 and 7. In tightening the belt 6 as shown in Fig. 3 the shafts 75 and 12 are operatively connected.

In order to promptly turn the auto-binder at right angles the operator throws the main bull wheel out of gear and reverses the grain wheel 1. In order to reverse this grain wheel 1, I provide the rear shaft 12, adjacent to the drive belt pulley 7, with the internal gear 3 shown in enlarged detail in Fig. 4. This gear is loosely held upon the shaft 12, between the collar 30, and the bearing 23. In normal engagement with the internal gear 3, is the spur pinion 2 held upon the pintle 80, this pintle being carried by an arm 23, while keyed to the shaft 12, meshing with the spur pinion 2 is the spur wheel4. In order to reverse the shaft 12, the operator merely throws the belt pulley lever 9 in the proper direction so that the ratchet faced pulley 7 will engage the y ratchet face 30 of the internal gear 3. Then in tightening the belt 6 the driven belt pulley 7 may be brought into engagement with said internal gear to rotate the same.

As disclosed the foot lever 26 is held to an ear 81`, secured to a suitable part of the binder frame 27 as shown in Fig. 3, so that the groove shive 28 may be thrown against the belt 6, to tighten the same as shown in Fig. 3. The foot lever 26 is placed in front of and below the seat 83 as shown in Fig.

2, this seat being held upon the post 7 The L seat 7, is held to a frame portion fixed to the upper end of the post 5.

Held within the bearing 47, shown in Fig. 5 and secured to the. forward end of the tongue 46, is the steering shaft 29, at its end carrying the bevel pinion 84, in mesh with the gear 56. At its upper end the steering shaft 29 is provided with the steering wheel 85, this wheel being held in front of and proximal to the seat 83.

Harvesters as usually constructed are provided with a set of so called transport truck wheels which' are detachably secured to a suitable part of the binder. By means of these wheels the binder is drawn to and from the field. When the transport wheels are in use the tongue 46 is detached and is secured to the end of the binder platform below the grain wheel l. This construction permits the implement being carried through comparatively narrow gates. In my invention, in order that the transport wheels may be driven by the motor M, I provide the driving shaft c with the chain sprocket 51. A suitable chain is made to pass over this sprocket 51 and other suitable chain sprockets secured to the transport truck wheels. These wheels can then be used as drive wheels in drawing the binder to and from the field. Vhen the transport truck wheels are removed the chain is removed from the sprocket 51. As the transport wheels do not form a part of my invention they have not been shown in the drawings.

In guiding the auto binder in a circular path, the machine is steered by means of the caster wheel 55, and the grain wheel 1.

From the foregoing it will be understood that the shaft 12 is controlled by means of the foot lever 26, through the intermedium of the belt 6 and the'connected pulleys.

In removing the steering shaft and caster wheel the auto binder can at once be drawn and operated by means of suitable draft animals.

The binder mechanism is operated by the motor. Under these conditions even in the heaviest grain there will be no choking of the binder mechanism for the reason that where the stand of grain is particularly heavy the auto binder is slowly advanced, while the operating mechanism is working at its maximum speed. This construction also eliminates any stalling of the auto-binder as is the case where the binders are driven by the bull wheels, as when the machine is drawn by draft animals.

As the auto-binder is used but a very short time during each year, the motor M, is detachably secured to the platform so that the same may be drawn forward off of its platform and be used in driving other machinery.

The shaft 12 is held at its outer end within a bearing bracket 86, and at its projecting end has the chain sprocket 85. The grain wheel 1, has a chain sprocket 87 and connecting this sprocket 85 and 87 is a chain 13.

The shaft 68 is connected to a transmission of any approved construction including two forward speeds, one reverse and one out of gear.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In a device of the character described in combination, a main shaft, a pinion at the end of said shaft, a driven shaft, a clutch gear on said driven shaft in mesh with said pinion, a clutch chain gear upon said driven shaft, means to operate said chain gear, a pinion secured to said chain clutch gear and splined to said driven shaft, a transmission gearing, a shaft extending from said transmission gearing, a bull wheel, and means to operatively connect said bull wheel to said transmission gearing shaft.
