To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residingat Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a full, clear, and exact specification.

My invention relates to grain binders.

In my prior Patent No. 994,711, patented June 13, 1911, I have described and claimed a clutch controlling mechanism for a binder wherein the shaft carrying the compressor or binder trip of the binder, upon the actuation of that trip, is moved bodily to disengage from the rotating finger of the binder clutch a slidable clutch controlling member operatively connected to the shaft, this olutch'controlling member being automatically held out of engagement'with the clutch finger by a cooperating cam mechanism to permit a third revolution of the binder clutch and the operation of the sheaf binding and discharging mechanism.

My present invention has for its ob iect to improve and simplify the constructlon of such a mechanism in such a manner as to increase its efiiciency by rendering it more sure in its operation and reducing the amount of wear upon the parts. A further object of my present invention is to provide a sliding trip mechanism of the type covered by that patent especially adapted to use in connection with a shocking machine having a movable sheaf delivery member, means being provided for controlling the binder mechanism in accordance with the requirements of such a shocker; z'. 6., for interrupting the sheaf discharging mechanism on the binder at a fractional point in its'cycle of operation until the sheaf delivery member of the shocker is in position to receive the sheaf discharged by that mechanism.

I attain these objects by providing improved mechanism for controlling the binder clutch whereby, when adapted to'use in connection with a binder alone, the general efficiency of thedevice is increased as outlined above and whereby, when used in connection with a shocker of the character mentioned, the mechanism is adapted to control the binder clutch, locking and unlocklng the vsame at a point intermediate the ends of the normal cycle of operation of the binding and discharging mechanism, in timed relation with respect to the movable sheaf delivery member of the shocker.

In order that my invention may be clearly and fully disclosed, I have shown for'purposes of illustration in the accompanying drawings two embodiments Which it may assume in practice, illustrating the same as 'adapted'to use in connection with a shocker of the "well-known Raney type.

In these clrawingsv Figure 1 is a front elevation of'a binder equipped with my improvements and having a shocker operatively connected thereto, certain of the parts being omitted to facilitate clear-ness of illustration;

Fig. 2 is a side elevation of the clutch controlling mechanism looking at the same from the sheaf delivery side of the binder;

Fig. 3 isa detail view of a part of the construction shown in Fig. 1, showing more clearly and in an enlarged view the mounting of the compressor shaft and the'connection of the clutch controlling member thereto; Y

Fig. i is a detail front elevation of a modified form of the clutch controlling mechanism shown in Fig. 1.

I The binder shown is of standard construction comprising a 'machine frame 1 having a binder deck 2 supported thereon by suitable supports 3, a binder frame 4, a breastplate 5, a binding needle 6 carried on the needle shaft 7 journale'd on the frame, discharge arms 8 carried on a knotter shaft 9, packers '10 carried on a packer shaft 11, a clutch 12 having a movable clutch finger 13, and a compressor shaft 1% having a trip 15 connected thereto and normally extending upward through the deck 2, all of these parts being operatively connected and operating in a well-known manner, the COIIlpressor shaft 14 being movable with the trip 15 in a slot 16 in an extension on the lower end of the frame 4, and connected, through a link 17, to an arm 18 operable by the cam wheel mechanism 1-), while the needle 6 is connected, through a crank 20 and a link 21, to a lug 22 rotatable with this cam wheel, as described in my patent mentioned above.

As in the manner described in that patent, when the trip 15 is forced downward and backward toward the full line position shown in Fig. 1 by the grain packed against it by.

the packers 10, a sliding trip member 23, movable longitudinally through a stud 24 on the front of the frame 4, is withdrawn from its normal position in the path of the rotatable finger 13 of the clutch 12 so that this clutch may connect the sheaf binding and discharging mechanism. In that patent the clutch controlling member extends part way around the shaft 14 and has an upwardly extending curved tail portion engageable with a cam movable with the needle crank, and at its upper end connected only to a spring mechanism carried on the frame which normally holds this clutch controlling member in contact with that cam, the compressor shaft 14 when moved bodily stubblewardly bythe actuation of its trip, withdrawing the clutch controlling member from engagement with the clutch, and the cam holding that member out ofengagement in such a manner that the latter can complete its third revolution. In my present construction, however, the member 23 is in the form of a flat strap having its stubbleward end 25 hooked around the lower end of a normally vertically disposed member 26 pivoted at 27 at its upper end to the frame 4 and pivoted on the shaft 14 at a point between its connection to the strap end 25 and its pivot on the frame. This member is also provided with a projection 28 on its lower end extending laterally from a point adjacent its pivot on the shaft 14, which projection is engageable with a cam 29 movable with the needle crank 20. Further, in lieu of the spring connection directly between the frame and the free end of the clutch controlling member as described in .my prior patent, in this construction I provide a spring and rod connection 30 between the member 26 and the frame 4 at a point'preferably between the pivots of this member 26. Further, I provide a stop 31 on the upper end of this member 26 adapted to engage with a coiiperating stop 32 on the frame 4 to limit the movement of the member.

In adapting my invention to use in connection with av grain shocker of the type wherein a swinging sheaf delivery member is used, it is desirable that means be provided for interrupting the connection of the binder clutch at a point intermediate the ends of the normal cycle of operation of the sheaf binding and discharging mechanism, preferably after the latter has moved through approximately two-thirds of its cycle of operation; '5. 6., after the sheaf has been. bound and the sheaf discharging mechanism has moved through a portion of its operation but before that discharging mechanism has completed its operation. In adapting my construction to such a use (referring first to Fig. 1) I provide a second normally operative clutch controlling member 33, which is also preferably in the form of a flat strap slidable through a second stud 34, in this instance formed on the frame 4 at a point beneath the stud 24. This strap extends stubblewardly and then upwardly, where its upper end, as shown at 35 (Fig. 2) is bent around the upper end of a crank 36 resiliently mounted at 37 upon the under side of the binder deck 2 and having a rearwardly and downwardly extending shank 38, pivotally connected at 39 to a stubblewardly extending link 40, which is, in turn, pivotally connected at 41 to a binder lock operating or tripping member 42, pivoted at 43 on a standard 44 carried on a support 45, which protrudes stubblewardly beneath the binder deck 2 and normally acts as a support for the swinging sheaf delivery member 46 of the shocker when said member is in sheaf receiving position. It is thus seen that when the fork or sheaf delivery member 46 of the shocker depresses the tripping member 42 to the dotted line position shown in Fig. 1, the effect of this movement is to withdraw the clutch controlling member 33 from its normal or clutch engaging position shown in Fig. 1, wherein it is held by the spring 37 However, it is necessary 100 that this clutch controlling member 33 cooperate with the clutch controlling member 23 and operate in timed relation therewith so that while the member 23 controlsthe binding of the sheaves, the member 33 acts 105 to interrupt the completion of the dischargeof the sheaves until the sheaf delivery mem ber 46 has returned to the dotted line position shown in Fig. 1 and depressed the trip 42. I accordingly connect these two members 23and 33 by means of a slotted link 47 pivotally connected at its grainward end at '48 to the free end of the crank on the end of the compressor shaft 14 and slidably connected at. its stubbleward end to the member 36 through a longitudinally extending slot 49.

In the operation of this embodiment of my invention in connection with a shocker, it is to be understood that the sheaf delivery member 46 of the shocker normally occupies the lower dotted lineposition shown in Fig.

1, wherein it depresses the trip 42, and that when a sheaf is delivered thereto by the sheaf discharge arms 8 of the binder, this 1 25 sheaf actuates suitable controlling mechanism; as, for instance, a trip 50 operatively connected to the operating mechanism of the sheaf delivery member (not shown), the sheaf delivery member being moved back and forthbythis operating mechanism into and out of engagement with thetrip 42 as it delivers the sheaves. Obviously, in the first operation of the mechanism; 2'. 6., when the sheaf delivery member and other parts are in the normal or dotted line position shown and the grain first commences to be delivered to-the packers 10, the supplemental clutch controlling member 33 will be held out of engagement with the clutch finger 13 due to the depression of the trip-42 and the connection of the clutch controlling member to that trip, so that the first sheaf will be bound and discharged to the sheaf delivery member 46 in the usual manner, the binder parts returning to. their usual positions after the discharge of a sheaf, as shown in dotted lines in Fig. 1, the sheaf discharging arms 8 occupying their upper dotted line position and the clutchcontrolling member 23.being in engagement with the clutch finger 13. As this first sheaf has, however, actuated the tripping mechanism 50 for the fork and the latter moves up from its lower dotted line position, the trip 42 will obviously be raised by the spring 37 to the full. line'po-sition shown and the clutch coi'itrolling member 33 will also be returned to its normal or operative'position, but will perform no function due-tothe engagement of the member 23 with the clutch finger. IVith the parts thus positioned, the packers 10 then proceed to pack the grain forthe next sheaf against'the compressor trip 15 until this trip is'forced backward by the pressure of the grain, whereupon, through the connection of the clutch controlling member 23 to the compressor shaft 14, this clutch controlling member '23 is Withdrawn from engagement with the. clutch finger 13 and the binding operation begins. During the whole of this binding operation the clutch controlling member 23will be held out of engagement with the clutch finger 13 by the cam 29 so that, so far as the member 23 is concerned, the clutch finger could rotate through its normal three revolutions. However, through the connections 'of the member 33, the-latter is thrown into the path of this clutch finger l3 afterthat finger starts on its second revolution in such a manner that it will interrupt the connection of theclutch after the clutch finger has completed its second revolution; 2'. 6., when the sheaf discharge arms 8 have completed sub stantially two-thirds of their normal cycle of operation and occupy the lower dotted line position shown in Fig. 1. In this position, with the sheaf bound and the discharge arms 8 resting against the sheaf ready to discharge it, the parts will remain until the sheaf delivery member 16 returns into engagement with the trip 12 and depresses the latter, whereupon the clutch controlling member 33 will be againwvithdrawn from vmember .thenwaiting to receive it.

-- In Fig: 1.1 h'ave'illustrated a modified form ofthe construction shown in Figs. 1 and'2, wherein the deviceis constructed substantially in accordance with. the embodiment hereinabove described, but in'which,

instead of the slotted connection between the member 36 and the crank on the compressor shaft being adjacent the former member, it is provided adjacent the crank, a connecting strap 51 being-used. which has its outer end bent. aroundthe upperend .of the member 36 at 52 and has a loop" 53 provided thereon in n such-a manner as to form a slot. In this construction themember 51 acts also to perform the function of the clutch cont-rolling member. 33, and also has'its inner or.clutch engaging end bent upward, as shown at 54, so that it may pass through the same lugQlwhich acts as a guide for the upper. clutch controlling member. 23, .the two. members being worked back and forth above orbeneath each other by the connecting mechanism in the same sequence asthat heretofore described in connection with the embodiment of my invention shown in Fig.1. It is also to be noted that in thisconstruction the secondary clutch controllingmemberhalso. acts to interrupt the rotation of the clutch finger 13 ata point substantially atrthe end ofthe secondv revolution of the latter rather than at a point a trifle beyond the end of this revolution, as is the CZISGL when a construction of the type shown in Fig. 1 is employed.

V'Vhile -I have in this application specifically described two embodiments which my invention may assumein practice, it is, of course, to be understood that the forms shown herein are used for purposes of illustration and the invention is not necessarilylimited to embodimentin these forms.jthe spirit'of the inventionbeing capable of being adapted to use inother'formsL What Izclaim asmyinventiomand desire to secure by Letters- Patent, is:
