14 Claims.

This invention appertains to harvesting, and more particularly to an improved attachment for mowing machines.

It has heretofore been proposed to provide harvesting attachments formowing machines, in which the cut crops can be laid either in windrows or bunches to facilitate the gathering thereof. However, all such attachments, with which I am familiar, fail to effectively accomplish their purpose. In most instances, the short material is lost before the same is bunched or laid in windrows; in other machines the increased draft is objectionable, and the turning around of the machine is difllcult.

Therefore, one of the salient objects of my invention is to provide a novel harvesting attachment for mowing machines, which will be free of the above mentioned objections, and which is so constructed that the cut crops can be laid either in bunches or windrows at the will of the operator without material loss of the short stuff.

Another important object of my invention is the provision of a novel attachment for mowing machines in which the cut material can be laid either in windrows or bunches at the will of the operator and out of the way of the mowing machine and the draft animals or tractor on the next round, so that no seed will be lost and the crop will not be injured in any way.

A further object of my invention is the pro vision of novel means for forming the bars, or slats, of the attachment, whereby the bars, or slats, will be free to swing, so as to facilitate the riding of the bars over uneven ground and obstacles, and to facilitate the turning around of the machine.

. A further important object of my invention is the provision of an attachment for mowing machines, in which the loss of all short material is precluded by the employance of means for bunching the cut material adjacent to the cutter, or finger-bar, of the mowing machine, with means upon the release of the bunched material for guiding the same to one side of the machine, whereby the bunches will be out of the way on the next round.

.A still further object-of my invention is to provide an improved attachment of the above {,0 character for mowing machines, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be applied to conventional mowing machines at a small cost.

With these and other objects in view, the iniii) vention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which: 5

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter M generally indicates a mowing machine,

and the letter A my improved attachment therefor.

The mowing machine M can be of any preferred character or make, and includes theframe l5 supported byfsuitable wheels 5. The frame has hingedly connected thereto in the ordinary manner the swinging cutter, or finger-bar, H. The frame I5 has also connected therewith in any preferred manner a support I8 for the drivers seat l9.

As shown in Figure 1, my improved attachment A consists of an elongated supporting plate 20, which extends parallel with the cutter, or finger-bar, ll of the mowing machine M, and the supporting plate 20 is rigidly connected with the bar H in any preferred manner, such as by the use of yokes, or straps, 2 I.

Rigidly connected with the supporting plate 20 is a plurality of equidistantly spaced, rearwardly extending parallel flat bars, or-slats 22. These slats successively decrease in length toward the outer, or left-hand, side of the machine (see Figure 1) for a purpose which will be later set forth.

It is also to be noted that I provide a relatively heavy bar 24 disposed adjacent to the inner end of the cutter, or finger-bar, and that the outer end of the relatively heavy supporting bar 24 is angledrearwardly and laterally, as at 25. This angled portion 25 of the supporting bar has connected thereto additional, spaced parallel bars, or slats, 26, which are disposed substantially in rear of the mowing machine.

These slats or bars 26 also successively decrease in length toward the left, behind the hopper. All of the slats or bars 26 are connected to the angled portion 25 of the supporting bar 24 by means of vertical pivots 21, so that the said bars 26 can swing in a horizontal plane. If desired, these slats or bars 26 can be made rigid with the supporting bar 24.

The longest of the bars or slats 22 are provided with pivot joints 28 intermediate their ends, so that the rear portions thereof can also swing in a horizontal plane; By referring to Figure 1, it will be noted that the pivot points of the rear swinging ends of the bars or slats 22 approach closer to the fingeror cutter-bar H at the left-hand side of the machine.

The extreme ends of all of the slats or bars 22 and 26' are provided with upwardly and laterally curved extensions 29. These curved extensions prevent the bars from catching on the ground and-facilitate the turning and delivery of the cut material to one side of the mowing machine.

Arranged on topof the slats or bars 22 is my novel buncher or hopper 30. This buncher or hopper 30 is of a substantially U-shape in plan,

and is preferably formed from sheet metal of the desired gauge.

As shown, the buncher or hopper includes rearwardly extending, inwardly inclined side walls 3| and a connecting rear wall 32. The for ward ends of the side walls 3| extend over the cutter or finger-bar 21 and are pivotally mounted upon horizontal pivots 33 carried by the end guard shoes or lifters 34 and 35.

In use of this form of my invention, the mowing machine M is operated in the ordinary way, and as the crop is cut the same is collected on the bars, or slats, 22. The hopper, or buncher, 30 will prevent the material cut from passing over these bars, or slats, and the material will be effectively gathered in a bundle or bunch.

When the bundle or bunch is of the desired size, the hopper, or buncher, 30 is raised, and the hunch is then allowed to feed rearwardly against the curved portions 29 of the bars, or slats, which "guide the bunch in rear of and to one side of the machine, and completely out of the way of the machine on its next round.

, As the bunch is formed directly adjacent to the the slats, or bars, 36, and the same are placed in enlarged openings 38 formed in the supporting plate 20. By this arrangement, the supplemental slats, or bars, 39 are permitted to rock both in a vertical and horizontal plane, which allows C'.

the riding of these slats over uneven ground and other obstacles.

When the mower is being turned around, the outer ends of the slats 22 rock on their pivots 28, and the slats 26 rock on their pivots 21, which allows the slats to readily follow the machine around a curve, and hence facilitates the ease of travel of the mowing machine. The supplemental slats will also rock in a horizontal plane during the turning of the machine.

The hopper, or buncher, 30 is raised and lowered in a novel manner, which will be later described in detail.

Referring more particularly to Figure 2, it can be seen that I have shown a slightly modified form of my invention, and in this form the bunches or windrows, as the case may be, are guided and dropped in such a manner that the mowing machine on its next round will straddle the bunches or windrows, and the draft animals can walk on each side of the bunches or windrows.

Thus, in this form of my invention shown in Figure 2, I employ relatively short slats, or bars, 46, which have their forward ends hooked in the manner shown in Figures 4 and 5, and these hooked ends are placed through suitable openings 4| in a supporting plate 42. .This supporting plate 42 is connected by means of straps 43 to the rear edge of the finger-bar 44 of the mowing machine.

Particular attention is called to the fact that the slats, or bars, on the outer, or right-hand, side of the attachment are longer than the inner set of bars, and that these long bars, or plates,

have their outer ends curved upwardly and laterally of the hopper, as at 45.

The long bars, or slats, are formed progressively shorter in length toward the extreme outer end-of the "attachment, and the bars and theircurved terminals form means for guiding the cut material to its desired point of deposit. The group of short bars, or slats, 40 can alsohave their rear ends slightly upturned, as at 45, to

.facilitate their travel over the ground.

Rockably mounted on the slats 40 is the hopper, or buncher, 41, which is of the same character as the hopper, or buncher, 38. In this form, however, one side of the buncher can be pivoted to the outer shoe 34 of the finger-bar, and the other side of the hopper, or buncher, can be pivoted to an upstanding foot 48 formed on the inner end of the supporting plate 42.

By rockably mounting the bars 40 on the supporting plate 42, the bars are enabled to ride over uneven ground and obstructions, and are permitted to follow the mowing machine during the turning thereof.

The hopper, or buncher, 41 is raised and lowered in the same manner as the means employed for raising and lowering the hopper 38, and this raising and lowering means will now be described in detail.

To bring about the raising and lowering of the hopper 30 or 41, as the case may be, I rigidly secure to the rear wall thereof an angle-shaped bracket 58. The ends of the angle-shaped bracket 58 have formed thereon attaching feet 5| provided with openings 52, by means of which the bracket can be bolted or riveted in position.

The body portion of the bracket has formed therein an enlarged opening 53 for the reception of a pivot bolt 54 (see Figure 3). This pivot bolt 54 rockably supports a cufi, or sleeve, 55 having formed on one end thereof the arm 55 through which extends the pivot bolt 54.

' The bore 56 of the cufi', 01' sleeve, has the lower part thereof slightly tapered, and this cuff carries angular related set screws 51 and 58 above the tapered portion of the bore. These set screws are adapted to impinge against the lift rod 59 when the liftrod is placed in said bore.

Thus, the set screws normally urge the lift rod toward the tapered portion of said bore to firmly clamp the lift rod in place.

By loosening the set screws 51 and 58 at the sleeve, or cuff, the hopper can be shifted from side to side to permit the desired adjustment thereof, and the foot lever 54 can be raised or lowered and adjusted to the desired position to suit the operator. The raising and lowering of the foot lever 64 turns the rod 59.

The inner end of the lift rod 59 is provided with an offset bearing portion 68, and this bearing portion is rockably mounted in a bearing opening 6| formed in the main supporting bracket 52. Formed on the offset bearing portion 68 of the' lift rod 59 is a lever, or operating arm 63, which in turn has formed on its upper end the foot pedal 84. I The main supporting bracket 62 is rigidly bolted to the frame of the mowing machine M, and the upper end of the main supporting bracket 62 is twisted and has formed thereon the right angularly extending attaching foot 55. This attaching foot 55 extends under the seat support lBof the mowing machine, and is clamped firmly thereto by the use of a clamp plate 85, which engages the outer face of the seat support. Suitable bolts 61 extend through the clamp plate 65 and the foot 55, so as to draw these members into intimate clamping contact with the opposite sides of the seat support.

Rig'ldly bolted to the main supporting bracket 82 at a point intermediate its ends is an auxiliary supporting bracket 58. This supporting bracket 58 includes the attaching arm 69 and the right-angularly extending supporting arm 18, which has formed therein the longitudinally extending slot 1|.

Adjustably mounted on the supporting arm 18 of the auxiliary bracket 58 is the suspension arm 12. This suspension arm 12 has its outer end twisted at right angles, as at 13, and is provided with a bearing opening 14. A plurality of openings 15 is formed in the body portion of the suspension arm 12 for selectively receiving the adjusting and clamping bolts 16, which extend through the slot 11.

An adjustable link 16 is rockably mounted on the twisted end 53 of the suspension arm, and the body portion of the link is provided with a plurality of bearing openings 11, any one of which is adapted to receive the supporting pivot bolt 11', which extends through the bearing opening a 14 of the suspension arm.

The lower end of the link 15 is twisted at right angles, as at 19, and has formed therein the bearing opening 88. The link 16 rockably supports the latch lever 81, which is of a particular construction, which will be set forth in detail} The extreme upper end of the latch lever 8| has formed thereon the right-angularly extending attaching car 82 and the bearing opening 83.

A pivot bolt 84 extends through the openings :5

and 83, and pivotally unites the latch lever to the link. A dog, or stop lug, 85 is formed on the pivot ear 82, and a stop pin 86 is carried by the lower twisted end 19 of the link in the path of the lug 85', so as to limit the swinging movement vided with a keeper nose 85, and the edge of f the lever below the nose 86 curves outwardly away from the nose, as at 81, toward the bill of the hook 85. The curved portion 81 of the latch lever extends at an angle to the inclined portion 88 of the body of the hook 85.

When the operator desires to drop a bunch of the cut material, a downward thrust is exerted on the foot pedal 64, which will rock the offset bearing portion 60 of the lift rod in the bearing opening BI, and bring about the raising of the outer end of the lift rod and the elevation of the hopper, or buncher, 38 or 41, as the case may be. Obviously, during the swinging of the lift rod, the cuff, or sleeve, 55 can rock on its pivot 54.

As the operating arm 63 swings downwardly, the same will move against the body portion of the latch lever 8| and swing the latch lever on its pivots 18 and 84. When the operating arm 53 rides past the keeper nose 86, the lat-ch lever will swing back and move the nose over the arm 63, and thus retain the arm in its depressed position, and the hopper, or buncher, in its elevated position.

Upon continued downward movement of the arm 53, the same will be guided by the inclined a face 81 into the hook 85. The hook will limit further downward movement of the arm, and upon release of pressure on the pedal 54 by the operator, the weight of the hopper will tend to swing the arm 63 back to its elevated position.

The arm will ride on the inclined face 88 of the bill of the hook, and will be guided past the nose 86 before the latch lever 8| can swing back to its locked position.

Obviously, when windrows are being formed, the arm 63 is left latched in its depressed position for holding the hopper raised.

In Figure 15 I have shown my improved device connected with a tractor T, which can be of any desired character or make. Any desired type of drawbar or the like can be employed for connecting my device to the drawhead or other part of the tractor.

In this form of my invention the buncher hopper or basket is pivotally connected at its forward end to the cutter bar in the same manner as in the forms of my invention previously described. Adjacent to the rear end of the buncher an upstanding rigid arm 9| is secured thereto, and this arm can be braced in any desired manner, such as by the downwardly and forwardly inclined brace bar 92. The upper end of the arm 9| is preferably twisted at right angles, as at 93, and has secured thereto a pull chain or cable 94. This cable extends toward the tractor T and is secured to the upper angle end of an operating hand lever 95. The lower end of the hand lever is .rockably secured, by means of a pivot bolt 96, to an appropriate part of the frame of the tractor, such as to the differential housing.

The lever 95 is preferably arranged adjacent to the seat 91 of the tractor, whereby the lever can be conveniently operated by the driver of the tractor. In order that the lever can be actuated from the foot, a suitable pedal 98 or the like can be secured to the lever adjacent to the lower end thereof. The lever and the pedal can be provided with aplurality of openings, whereby adjustment of the pedal can be had. I

By swinging the lever forwardly, the hopper wall 30 may be raised to release the bunched material at a substantial distance in front of the upturned rear ends 29 of the trailing bars or slats. Due to its frictional contact with the ground between the slats, the bunched material ceases its forward movement and the slats are drawn underneath it until the upturned rear ends are brought into contact with it with a compacting and laterally pushing action, which effects a bodily delivery of the bunch to the space in the rear of the bull wheels of the mowing machine.

The mode of operation above described is quite different from that of the ordinary windrowlng attachment, in which the cut material gradually accumulates against the upturned end portions of the slats, with much of it finding considerable anchorage between the slats, and some short or straight portions being allowed to escape between the slats before such escape is blocked by other material accumulating against their upturned ends.

By my .improvement, all of the material is first gathered and massed by the hopper wall 30 against the portion 32 thereof, and since no portions of the stalks or fiber can extend through this wall, the contacting portions are turned to a position of parallelism with the wall. When the wall is raised, some of the stalks may react resiliently, but enough of them will remain substantially parallel with the portion I2 of the wall so that the entire bunch will immediately commence to move laterally when struck by the upturned ends of the slats, the bunch being delivered bodily substantially with a kickingaction instead of having portions detained by anchorage between the slats. Such anchorage tends to disintegrate the bunch by delaying delivery of portions thereof.

My improved buncher or hopper wall is also effective to accumulate the cut material in proximity to the cutter and finger-bar, whereby the mass is accumulatedbefore the combing effect of the stubble can swing any large percentage of the stalks to a position of parallelism with the slats. Therefore much waste is prevented, since straight stalks parallel with the slats may pass between them, particularly if allowed to reach the upturned portions 29 While in such positions.

It will be observed, in Figure 1, that the portion 32 of the hopper wall is in close proximity to the ends of the auxiliary slats 36, and, therefore, when the auxiliary slats are used, the preliminary bunching of the material may be wholly accomplished with their aid.

It will also be observed, in Figure 15, that the arm 9| extends upwardly from the rear portion of the hopper wall for a substantial distance. This arm is braced against forward stress by the bracing member 92, which has its front'end secured to the pivot connection between one of the side arms of the hopper wall and the connectorbar 42. By attachingthe upper end of the arm 9| to a cable-like connection 94, I am able to elevate the hopper Wall from a forwardly distant tractor, such, for example, as a tractor which has been substituted for horses as a means for propelling, the mowing machine.

The powerto lift the hopper wall may thus be applied through the cable from a point sufliciently distant in a forward direction to avoid objectionable thrust or tension, and also at a sufficient height to avoid objectionable thrust of the hopper wall upon its pivotal Therefore, the hopper wall may be elevated to release bunched material by a simple pull upon a connecting cable, and any suitable means may be employed for applying tension-to the cable.

Changes in details may be made without departing from the spirit or the scope of this invention.
