My improved buncher is secured to the threshing machine by means of suitable brackets 17 rigidly secured to the rear end of the threshing machine frame. Said brackets are designed to carry a transversely arranged shaft 18 which provides a pivot member for suitable brackets 19 to which the buncher is attached.

The buncher comprises side members 20, the lower edges of which are formed circular from pivot points 21. The front ends of the side members 20 areconnected by a curved plate 22, the upper edge of which terminates at a point substantially in line with the riddles 15. The lower edge of each of the side members 20 is provided with a hinged sector 23. The said sectors have their lower edges adapted to swing inwardly for purposes hereinafter made clear. The top edgeof the side members 20 are substantially par allel with the lower edge of the hood 13.

The buncher frame is pivotally supported so that its free end is adapted to swing upwardly and downwardly. The buncher is supported against downward movement by means of suitable rods 24 havingtheir upper ends slidab-ly mounted in brackets 25 and provided with screw threaded nuts 26 for adjusting the height of the buncher relative to the hood 13. The rods are slidably mounted to permit upward movement of the launcher tn permit it to ride over obstructions and the li re. V i

Each of the brackets 18 is provided with a downwardly and rearwardly extending runner 27. These runners are normally carried a slight distance above the ground surface and protect the bottom of the b uncher by making engagement with the ground surface before the bottom has engaged the ground.

. The free end of the buncher is free to move upwardly when such engagement is made.

The buncher is providedwith a flexible bot tom or dumping member 28, which may be formed of canvas or other suitable material,

": havingtransversely arranged reinforcing devices 29.

parting yieldahle and rearward movement to the bottom member.

The forward edge of the member 28 is provided with a transversely arranged rod 33 designedto be supported by hooks 34 mounted on a rock shaft 35. As shown in Figure 3, the flexible bottom 28 is supported adjacent to the curved edges of the side members 20 'ith the forward edge of the bottom ad acent to the under surface of the curved plate 22. A spring 36 is provided for yieldably retainground surface.

ing the'hook devices into engagement with the rod 33, and to support the bottom member 28 taut against the curved edges of the side members. The yoke takes up any slack in the bottom member.

The shaft is provided with a trip arm 37 having a trip rod 38 which projects upwardly and forwardly along one side of the threshing machine, so it may be operated from any convenient point. Nhen it is desired to dump. the buncher, the rod 38 is pulled, causing the hooks 34 to disengage the rod-33, which will permit the flexible bottom member 28 to fall to the ground surface, and'to be moved rearwardly as the threshing machine is advanced over the The bottom member as sumes theposition shown by dotted lines in Figure 3. V

For returning the bottom member 28, I have provided a roller 39 supported by means of arms 40 which arepivoted by suitable rivets in the side members 20 in the pivot centers 21. the roller 38 is swung forwardly, the flexible bottom member will be gathered up and the outer ends of the arms 40 brought into engagement with the outer ends of the rod 33, after which the said rod will be forced into the hooks 34.

For mechanicallyoperating the roller 39,

I have provided in the upper ends of the brackets19 a shaft 41 having at each end a sheave 42. Each of'the sheaves is provided with a cable 43, the free ends of which are attached to the arms 40 in the manner clearly shown in Figures 1 and 2. Each of the sheaves 42 is rigidly secured to the shaft 41.

Referring to Figure 5, a sprocket wheel 44 is rotatively mounted on the shaft 41 having a hub 45, one end of which terminates in a clutch member 46. The other end of the hub is provided'with a ratchet wheel 47. The sprocket wheel 44, the clutch member and the ratchet are continuously rotated through a sprocket chain 48 driven from a sprocket 49 mounted on the shaft 18. The shaft; 18 has a sprocket 5O drivenby a sprocket chain 51 from'a sprocket 52 mounted on one of the wheels 12.-

Rotatively mounted on the shaft 41 adia-' cent to the sprocket 47 is a cam disk 53 hav ing a cam 54, on its periphery; The disk 53 is also provided with a pawl 55 designed to engage the ratchet 47 and having an outwardly extending lug 56. A spring 57 is thehooks' 34 are in engagement with the rod Tripping of the hooksr34 causes the free end of the arm 58 to move downwardly It will readily be seen that if out of engagement with the lug 56 and the pawl 55 to engage the ratchet i7, which in turn will cause the disk 53 to rotate in unison with the *atchet wheel, for purposes herein after made clear.

The clutch member is held out of onga 'ement by means of a pin (33 in the lever 6i and a hook 64. The hooh tiel is carried by a pivot lever (35. of the arm (31 provided The free end v, ih a trip bar 66, slidably mounted in a siutable hearing (37 having its free end dcsigncd to be engaged by a cam 68 mounted on the inner face of the sheave d2, adjacent to the dish o3. The free end of the lever 65 is ocsigned to be engaged by the cam The operation of this part of the mechanism is as follows:

i'issuming that the bottom member 28 is ended and it is desired to dump the same, th rod 38 n pulled, causing the hooks to re rod 33 and the bottom per- L to the ground surface. At the same time the lever 58 is lowered and the it; disen 'a cd, permitting the pawl 55 to 1 which will cause the ac cam 54 to travel tothe time the bottom in its dumping posh l vhnn the dumping 1s complete, the cam a reigugcs the free end of the lever (35, elevatme which mounted in a slotted rig in the member 67, caus"'i the lug 6i seng the pin (33, which wii 1 erniit the hers (l6 and 60 to engage, thereby 7 .e s alt ll to be rotated and with it the sheave 2 in a clockwise direction as 5.:houn in 1e ii, and the arms to he mo 'l forwardly, causing the flexible bottom member to be moved to its closed position. dust at the time the closing of the bottom member takes place the cam 68 engages the free enl of the bar 66, forcing the pin 63 bencath the lug G iand the clutch members lo ked into an open position, which will con tin i tl -e rotation of the shaft 41.

l-totativ mounted in the upper edge fl normal pnsi e of side niemberi-i 30 is a shaft 0 to which e i'l is attached. The said plate 71 is led to ban do \vnwa idly into l to swing "forwardly to the dot. p on shown in Figure 3 as the bunche s filled with. straw, forming what I shall term a division plate for preventing the straw within the bunoher from clogging the delivery end of the riddles 15 and from engaging the lower runs of the conveyor 14. The movement of the plate forwardly is limited by the shaft 41.

The shaft 7 0 is pivotally mounted in the side members 20 at a point above and rear ward of the pivot center 21, so that the free end of the plate 71 will swing somewhat e0 centrically within the buncher, to provide a space between its free end and the bottom of the buncher or the plate 22, which provides means for permittingchaff, which might gather on the top of the plate in its forward position of movement, to move downwardly into the buncher, and also permits the lower edge of the plate to swing above the chaff collected in the buncher from the riddlcslb during the time the plate 71 is moving forwardly. A spring 72 is provided for normally returning the plate 71 to its rearward position of movement. l

One end of the shaft 21 is provided with an arm 7 3, having an eye bolt 7 4 pivotally mount ed in its free end, which is d signed to slidably receive one end of a rod 7 5, said end being screw threaded and provided with a nut 76. The opposite end of the rod 7 5 is pivotally connected to a short arm 76a1nounted on the trip shaft 35. The parts are soadjusted that when the plate 71 is at its extreme forward position of movement the eye bolt 7 a will engage the nut 7 6 and cause the hooks S l to be unlatched from the rod 33, thereby providing means whereby the buncher will be automatically dumped when it has become filled, to prevent clogging of the delivery end of the conveyor 14:.

On account of the rod 75 being slidably mounted in the eye bolt 74, this automatic trip mechanism in no way interferes with the manually controlled trip mechanism actuated through the rod 38, as it will readily be seen that asthe rod 38 is pulled and the shaft 35 rocked, the rod 75 will be slid upwardly through the eye bolt 7 4. This provides means whereby the operator may ordinarily dump the bunches of straw in wind rows. The automatic device is provided to insure against clogging in case the operator should forget to manually trip the buncher, or in case the wind rows are too far apart so that the buncher becomes filled before the succeeding wind row has been reached.

The nut 7 6 may be screwed downwardly on the shaft 74 and thus provide means whereby the buncher will be automatically dumped before it is filled, in which casethe operator may permit the machine to dump automatically on the first round or two, and thereby provide means whereby the proper spacing of the wind rows may be easily and quickly determined. After the first round has been lOi] permit the automatic device to operate only when the buncher has become completelyfilled." a

The wind rows will then be so spaced apart that the buncher will bedumped automatically before it is filled, and thus provide means whereby allowance may be made for variation in the quantity of straw fed to the buncher between the wind rows, on account of the variation in the width of the swath being cut, as well as the variation in the quantity of straw between the wind rows.

Rotatively mounted in the upper rear end of the side members of the buncher, I have provided a shaft 77 on which is mounted a,

hollow cylinder 7 8 having substantially radially projecting teeth 79. The teeth 79 are arranged in series of circumferential rows, each row'being designed to operate in a slot 80 in a circular shield plate 81. The plate 81 is mounted eccentrically with the cylinder '78. The upper end of the plate 81 is mounted on a cross bar 82 supported by suitable arms 83 from the side members 20. The

lower end of the shield plate 81 is secured to an angleiron. 84 also mounted between the side members 20.

The shield plate 81 is mounted back of the delivery end of the conveyor 14 insuch manner: thatmaterial delivered from said conveyor will be thrown on said plate and engaged by the teeth 79 and moved downwardly and withdrawn from the slots 80 near the lower end of the shield 81, to cause the teeth to disengage the material and atthe same time force the material downwardly against the plate 71 and into the buncherrin such manner that considerable compression of the material] within the buncher takes place. One end of the shaft 77 isprovided with a pulley 85 to receive a belt 86,'by means of which the cylinder 78 is rotated through a pelt 86 and a pulley 87 mounted on the shaft Thus it will be seen that means is provided whereby the quantity of material carried by thebuncher will be considerably increased,

' as well as providing means whereby the bunch will be formed in a more compact and unitary manner so that when the said hunch is delivered from the buncher it will stand ordinary winds without being scattered over the'field. 4 p 1 Thus it will be seen that I have provided abuncher of simple, durable and inexpensive construction, which may be easily and quickly applied to the thresher of a combined harvester and thresher, and when so applied provides means whereby comparatively large quantities of straw may be collected and.

gathered in the buncher and then delivered totheground surface, without scattering, either manually or automatically, and provided in connection therewithme'ans whereby a minimum amount of attention is required on the part of the operator, which is an important factor in attachments of this kind, inasmuch as the operator has a large number of matters which require his attention.

It will further be seen that I have'provided a buncher which may be carried comparatively closeto the ground surface without injury.

The bottom edges of the members 20 are provided with the hinged members 23, which further. provide means against injury to the said bottom edges, inasmuch as said members would swing inwardly if the bottom member made engagement with the ground surface. The said members 23 also provide means for automatically taking up slack in the member 28, due to the weight of the load carried therein, as said members are usually swung inwardly at the time the member 28 is hooked up on account of the tendency of said member 28 to assume a straight line when tension is applied thereto.

This part of my mechanism, as well as the flexible bottom member, are clearly disclosed in United States Letters Patent issued to me on February 1, 1927, Number 1,615,928, and April 3, 1928, Number 1,664,659.
