HEADER ATTACHMENT.

Application filed 'August24,;1923. Serial 'No 659,135.

To all whom it may concern:

Be it known that I, JAMES A. Srnnn, a citizen of the United States, residing at liozel, in the county of'Pawnee and State of Kansas, have invented anew and useful Header Attachment, of which the following is a specification.

This invention relates to harvesting machines and more particularly machines commonly known as headers.

The primary object of the invention is to provide means for automatically unclut'ching the cutter bar. and gearing of the header while the machine is being turned in one direction. I

Another important. obj ect of: the invention to provide means for conveying the material laterally afterthe same has been cut by the machine. 1

A still further object ofthe invention is to provide means for manually controlling the clutch members ofthe machine to permit the endless conveyors to "be readily and easily thrown into and out of operation.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed, may be made within the scope of what claimed, Without departing from the spirit ofthe invention.

Referring to the drawings:

Figure 1 is a side elevational view of a header constructed in accordance With'the invention.

Figure 2 is a fragmented plan view thereof.

Figure 3 is a sectional view taken online UJ of Figure v Figure 4t 15 a sectional view taken on line -il4- of Figure 2.

Figure 5 is a sectional view taken on line 5 of Figure 1. I i Figure (-5 isa' longitudinal sectional view through the lateral adjustable. conveyor.

Referring to the drawings in detaihthe frame of the machine is substantially triangular and comprises a relatively'long rod bythearms 12 may lee-moved verticallyto adjust *the cutter bar with respect to th ground surface; v

Supportedby the axle "6 and secured there to a dj acentgto, the outer end thereof, are forwardlyeXtended arms 18 that have connection with the cutter,barsupporti-ngframe at the other side-thereof to; assist the arms 12 in supporting the weightof the cutter'bar and theframe.

The cutter bar frame includes a troughlike member 1 1 thatha-s openingsformed in the sidebarsthereot to receive the shafts 15 -on which theflrollers 16 aremount-ed, which rollers provide supports for the endless conveyor 17, Pivotally mountedon the rod 5 arefthe-supporting arms 18to which are secured the rods 19 thatextend rearwardly and have theinadjacentcnds connected by -means of the latch member 20 that carries a movable member 21-a'clapted to move in the -ope1nngs 22 of theadjnstingbar'23' that is sup-ported at the rear of thegmachine.

These arms 18 -a1s.o*have connection with the rods 24 and 25 that connect withthe upwardly extending arms 26 carried by the bearingslO, which arms also have connec' ,tion-with-the arms *12 throughthe rods 27.

Thus it will be seen-thatupon "1110V81116I1130f the rods 119, the arms 18 and rods connected therewithwill ;be moved to adjust the cutter bar'smporting frame vertically.

Forming'a part of the frame ofthe machine-is an auiiiliary frame including a rear wardlyextendmg-bari28 v'vh-ich has its rear end connected to the main frame of themachine by means of the-bar .29. The bar 29 supportsibea'rings 30 and 31in which the shaft 32 operates, the'shaf-t 32 carrying a pinion 33 at one end, and a sprocket 34 at the opposite end, the sprocket being designed to receive motion from the sprocket 35 through the chain 36 operating over the sprockets.

The sprocket 35 is secured to the wheel 37 so that movement of the wheel 37 will produce a relative movement of the sprocket 35 and chain 36 and sprocket 3 1. In order that the sprocket 34: may be clutched to the shaft 32 to operate the shaft 32 a clutch member 38 is provided and splined on the shaft 32, suitable means such as a lever 39 being provided for moving the clutch member 38 to its inactive position, the coiled spring 40 being provided to normally urge the clutch face 38 into engagement with the clutch face 11 formed on the hub of the sprocket 34.

Meshing-with the beveled pinion 33 is a beveled pinion .2 carried on one end of the shaft 13 that is mounted in bearing 44: and bearing 45 in the arm 16. A roller operat ing shaft is indicated at 47 and has connection with the shaft 43 through the universal connection 48, the opposite end of the shaft being connected with a roller 49 at 50, over which roller the laterally disposed endless conveyor 17 operates.

Secured to the rod 5 is a bearing 52 in which the shaft'53 is journaled, the bar 28 also supporting bearing member 54 in which the outer end of the shaft 53' operates. A

clutch member 55 is also mounted on the shaft 53 and cooperates with the clutch member 56 of the sprocket wheel 57 to lock the sprocket wheel to the shaft 53 and cause rotation of the shaft 53 and pinion 58 supported at the outer end thereof. The clutch member 55 is normally held in its active position through the medium of the spring 59 there being provided a clutch lever 60 in the form of a bell crank lever which is pivotally supported at 61 on the, 7 arm 61 to throw the clutch member 55 to its inactive position.

A rod 62 has connection with the operating clutch lever 60 and has its forward end connected with one end of the chain 63 operating over the sprocket wheel 64 that is mounted on the shaft 65; This shaft 65 is journaled in a bearing of platform 66 mounted at one .end of the rod 5, and as shown, supports the sprocket 64c to which one end of the chain 63 is connected. As the wheel 67 1s turned inone direction to guide the machine t is obvious that the shaft 65 will be operated to the end that the clutch member 55 will be automatically released, throwing the shaft 5? out of operation. i

If it is desired to manually control the clutch mechanism, the pedal 68 is provided, which pedal is pivotally supported on the platform 66 and has connection with the rod 69 which in turn is connected with the rod 62 to move and throw the clutch member 55 out of operation. Associated with the shaft is a shaft 70 that carries a pinion 71 meshing with the pinion 58 to receive motion therefrom. The shaft 70 also supports the pinion 72 that is in mesh with the pinion 73, mounted on one end of the shaft 74-. i The shaft 70 has connection with the shaft 75 that in turn operates the outer veyor 51 at 82, so that as the rods 19 are moved, the laterally extending conveyor may move therewith, to the end that the discharge end of the laterally extending conveyor may be adjusted vertically.

Mounted on the axle 6 is a sprocket 83 over which the chain 84: passes, which chain also moves over the sprocket 85 carried on the shaft 86 of the reel 87, for transmitting rotary movement of the axle 6 to the reel 87. A frame 85 has connection with the axle and carries sprockets 88 to hold the chain 8 1 taut at all times.

In the use of the device, it will be obvious that the device may be positioned adjacent to a suitable receiving wagon, the laterally extending conveyor having its upper end disposed over the wagon to discharge ma terial, thcreinto.

I claim: I

1. In a harvesting machine, a frame, a cutter bar, a conveyor operating at the rear of the cutter bar, a laterally etxended conveyor to receive material from the first mentioned conveyor, shafts, for imparting rotary movement to the laterally extended conveyor, shafts operating to transmit rotary motion to the first mentioned shafts, sprockets on the last mentioned shafts, clutch members operating to clutch the sprockets to the shaft, a steering wheel for the frame, and means controlled by the steering wheel and having connection with the clutch members for moving the clutch members to their inactive positions when the steering wheel is turned.

2. In a harvesting machine, a frame, a laterally disposed endless conveyor supported by the frame, shafts for operating the endless conveyor and having pinions, operating shafts having pinions meshing with the pinions of the first mentioned shafts, sprockets on the last mentioned shafts, clutch members for clutching the sprockets to their shafts, a clutch leveras- I sociated with one of the clutch members, a rod extending from the clutch lever, a steering wheelat the forward end of the frame and having a vertical shaft, a sprocket on the vertical shaft, a chain on the sprocket, said chain having connection with W the rod, and said chain adapted to move to operate the rod to throw out the clutch member when the steering wheel is turned.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JAMES ARTHUR SPEER.
