STRAW GUIDER FOR THRASHING MACHINES.

Application filed Qctobcr 12, 1922. Serial No. 594,155.

To aZZ whom 2'25 may concern:

Be it known that 1, JOHN J. NIEDERKORN, a citizen of the United States, and resident of Port Washington, in the county of Ozaukee and State of lVisconsin, have invented certain new and useful Improve ments in Straw Guiders for Thrashing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to straw guides for thrashing machines, and is particularly directed to an attachment adapted to be se-' cured to the blower pipe of an ordinary thrashing machine.

In thrashing machines, as ordinarily con structed, the straw is blown directly from the blower, or discharge, pipe into a pile. It frequently happens that the straw is scattered over a considerable area as the blast of air from the discharge pipe tends to interfere with the formation of a compact pile of straw. I11 addition to this, there is frequently a considerable amount of dust and dirt in the straw and this is, therefore, blown directly into the pile.

The primary object of this invention is to provide a machine which overcomes the above noted defects and forms a pile of straw in a compact manner and free from dust or dirt.

Further objects are to provide a straw guide which will direct the straw from the blower pipe in any desired direction, which will momentarily retain the straw and allow the dust to be blown away from it, which may be moved to inoperative position, if de sired, and which may be readily controlled from a position remote from the end of the blower pipe.

Further objects are to provide a straw guide which is of comparatively light weight, which is strong and durable, which is effective in operation, and which may be cheaply and readily produced.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a plan view of the blower pipe of a thrashing machine with the straw guide in place.

Figure 2 is a side elevation of the structure shown in Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 2.

Figure l is asectional view on the line 4-4. of Figure 2.

Referring more particularly to the drawings, it will be seen that the blower pipe 1 has the usual upturned portion 2 adjacent its outer or open end. It is provided with a pair of rigidly attached guide straps 3 which are provided with upturned guiding cams - 0r lugs 4 and 5, the lugs 5 being inturned, or turned over towards each other as may be seen from Figure 2, to provide stops whose function will appearlater. Supports are slidably carried by these guide straps and comprise bands 6 and 7 and brackets 8 and 9, respectively, secured thereto.

The brackets 9 are provided with bearings 10 within which are journaled the ends of a transverse hollow shaft 11. This shaft carries a plurality of spaced, curved straw guiding fingers 12 which extend beyond and in front of the end of the blower pipe. Arms 13 and ll are secured rigidly to the shaft 11 in any suitable manner, as by means of clamping rings 15. The central arm extends directly rearwardly and the side arms diagonally and rearwardly. They are all riveted together, as indicated at 16. The fingers 12 are preferably arranged in two rows, as shown, and in staggered relation.

.They may be supplemented by a transverse bar 17 to which each finger is secured.

The rear supportlng member composed of the band 6 and the bracket 8 is secured to the forward supporting member by means of an upper and a lower longitudinalbar 18 and 19, respectively, so that they will move in unison. The upper bar 18 is provided with laterally extending cars 20 curved to correspond to the curvature of the blower pipe.

The bracket 8 is substantially of inverted U-shape and straddles the rear end of the arm 18 to guide and limit its motion. A spring 21 is mounted within the bracket 8 and below the arm 13 and urges such arm upwardly.

The means for revolving the device about the end of the blower pipe may comprise a pair of cables 22 and 23 passed around sheaves 2 1 and 25 secured upon opposite sides of the blower pipe. The forward ends of the cables are attached to the ears 20. It will be seen, therefore, that by properly manipulating the cables the device may be caused to revolve about the blower pipes so as to point the fingers 12 in any desired direction.

It may be found desirable to vary the angularity of the fingers 12 to vary the action of the device. This is readily accomplished by means of a cable 26 passed be neath a pulley 2'7 and attached to the free end of the arm 13. By drawing upon the cable, the arm 13 is moved downwardly and the fingers 12 coiu'espondingly tilted.

The end of the blower pipe is relatively inaccessible and it therefore is desirable to provide means for controlling the device from a readily accessible point. This is readily accomplished by providing controlling drums 28, 29 and 30 at a point easily within reach of the operator, as for instance upon a lower portion of the blower pipe The cables 23, 2t), and 22 are 5 wrapped around and secured to the drums 28, 29 and 30, respectively. These drums are loosely mounted upon a supporting and operating shaft 31 provided with a crank ried in bearings formed in brackets 33 and 34 rig-idly attached to theblower pipe-1. A screw, or other securing means, '35 is mounted in the bracket 34 and has a reduced portion adapted to enter any of the grooves 36 formed in the shaft '3l to revolubly retain the shaft in any of its positions of adjustmentlongitudinally of its} bearings;

The shaft 31 is adapted to selectively operatively engage any of the drums. This isaccomplished by providing pins 37 and 38,which are secured to' the shaft and project from either side thereof. The pulley 29 is provided with an internal cylindrical cavity 39 within which the pin 37 may freely rotatep The pulley 28 is provided with a slot 40 within which the pin may seat, and by means of which the drum 28 may be operatively coupled to the shaft 31 when the shaft is slid to its extreme left hand position.-

corresponding drum.

The shaft is revolubly and slidabl-y car-' It will thus be seen that by longitudinally sliding the shaft 31 the pulleys may be selectively, operatively coupled thereto and may be rotated by means of the crank 32.

Pawls 44 are carried by a rod 46 carried by the brackets 33 and 3%,and cooperate with ratchet teeth &5 formed upon the drums-- one pawl being provided for each drum.

The operation of the device is as follows lVhen it is desired to shift the straw guide, the shaft 31 is slid into engagen'ient with one of the drums 28 O1. 30 and the pawl of the drum, which is not engaged, is raised. The crank is then rotated and the appropriate cable 22 or 23 wound upon its drum, the other cable unwinding from the lVhcn the desired position has been attained, the pawl is dropped into place. If it is desired to change the angularity of the fingers 12, the shaft 31' is slid until the drum 29 is operativelyjcoupled thereto, The crank is then rotated to move the cable 26 and correspondingly move the arm 13, thereby rocking the fingers '12.

It will be seen that a straw guide has been provided which may be pointed in any direction desired to correspondingly control the shaping of the straw pile and to prevent the scattering of the straw;

It will further be seen that the angular settingof the fingers maybe accurately controlled and' adjusted to suit any condition.

It will further be seen that the parts may be readily controlled from a remote point easily accessible to the operator.

I claim p A straw guide-for thrashingmachine having a blower pipe comprising a support slidably surrounding said pipe, a rock shaft carried by said support, spaced fingers projectingfrom said rock shaft, a lever operatively connected to said rock shaft, a spring positioned "between said lever and pipe, a cable attached to said lever, a pair of cables attached to opposite sides of said support,

means for guiding said cables, a plurality of drums to which said cables are attached, a manually operable slidably and revolubly mounted shaft loosely passing through said drums, and cooperative means carried by said drums and shaft, whereby when said shaft is longitudinally moved the drums are selectively coupled thereto.

In testimony that I claim the foregoing I have hereunto set my hand at Port Wash ington, in the county of Ozaukee and State of Wisconsin.
