BUNDLE-CARRIER FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent N o. 573,086, dated December 15, 1896 Application ined Decemtaaiee/i. seriaiNo. 530,971.' mombela To c/,ZZ' whom t Wray concern.'

Be it known that I, PAUL I'IANSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Bundle-Carriers for I-Iarvesters, of which the following is a specification.

It is usual in modern automatic grain harvest-ing and binding machines to provide mechanism constructed and arranged to receive the bundles of grain when formed by and ejected from the binding mechanism and to retain such bundles during the travel of the machine through the field until a sufficient number thereof has been collected, when they are discharged or deposited upon the ground at one operation.

The present invention'relates to appliances of this nature 5 and its object is to provide an improved construction simple, inexpensive,

durable, easily understood and operated for accomplishing the desired result.

A further object is to provide a carrier mechanism of simple and improved construction adapted to be easily and readily folded or collapsed, whereby the mechanismis enabled to pass by obstructions or through restricted openings.

A further object of the invention is to provide a carrier mechanism of simple and iinproved construction arranged and adapted to be so operated as to rapidly and easily effect a discharge of all the bundles or sheaves of grain collected therein.

Further objects of the invention will more fully hereinafter appear.

. The invention consists substantially in the construction, combinations, locations, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view in front end elevation of a portion of a grain harvesting and binding machine with my invention applied thereto, illustrating in dotted lines the position of the parts at a point in the operation thereof. Fig. 2 :is a view in plan of the same, showing in dotted lines a different position of the parts. Figs. 3 and 4 are enlarged detail views, in side elevation and plan, respectively, of parts of the carrier-operating mechanism. lFig. 5 is a detailed view iii plan of a slightly-modified form of carrierbperatingmechanism, illustrating in dotted Iines the operation thereof.

The samerefereuce-sign is employed to designate the same part wherever it occurs throughoutV the4 drawings.

A indicates a portion of the framework of 6o a harvesting-machine; B, the lelevatoi-deck thereof; C, the binder-deck; E, the masterwheeI; F, the knotter-operating shaft; G, the

needle, and D a portion of the binder-housing. These parts may be of any desirable or jconvenient construction and do not require specilic description.

S uitably supported adjacent to the delivery edge of the binder-deck arebrackets 5 6, extending stubbleward from the machine. In 7o said brackets is journaled a rock-shaft '7 of any 'suitable form or construction; but preff erably, in order to reduce weight and to afford better means of support for the ends of the bundle-carrying arms presently to be described, said shaft maybe in the form of a tube or pipe.

A series of swinging arms S are pivoted at their inner ends to rock-shaft 7, and are suitably bent to form a cradle when the parts are 8o in proper position, as hereinafter described morefully, adapted to receive the bundles of grain when formed and ej ecting from the bundle-forming mechanism. A bar lO, suitably perforated for the passage of arms S 8 5 loosely therethrough, connects said arms and assists in controlling and governing the movement of said arms and secures simultaneous movement thereof when said arms are folded or rocked to and from the position thereof 9o shown in dotted lines in Fig. 2, for a purpose presently to be described. In the form shown rock-shaft 7 is provided with a series oftransverse perforations, and the inner ends of the swinging arms 8 are reversely bent upon the 95 main body portion 'of said arms, as indicated in Fig. 3, and the bent portion is arranged to be received loosely in said perforations in the rock-shaf t, and are suitably maintained therein, whereby said arms are permitted a free Ioo rocking motion about the bent portions thereof. In order to permit said arms to rock closely into line with each other and against the side of the machine when the machine passes an obstruction, the grainward ends of said arms are given a slight lateral bend or offset from the stubbleward ends of the arms, as clearly shown in Fig. 2, and in order to further contribute to this desirable result the arms 8, adjacent to their pivoted ends, are provided with an acute bend, asat 8', Fig. 8, in the direction of the length thereof, thereby forming a substantially vertical portion between said bend and the bend forming the pivot above described. On this vertical portion is arranged the bar 10, Whicm as will be understood from the foregoing'description, is thus located in close proximity to and in a lower plane than the rock-shaft 7, thus permitting the bundle-supporting arms to rock into close proximity to the side of the machine and to each other, and this, too, Whether shaft 7 is rocked ornot, thus permitting the arms to be folded as well in their elevated position as when their outer' ends are depressed or low-l ered. By this construction is avoided the ob? jection of portions of the stalks of grain being gripped or clamped between the bar 10 and the'rocking bar or shaft 7 which would pre.- vent the bundles from being readily deposited or discharged, and hence would cause them to drag along the ground.

Reference-'sign 11 indicates an arm provided with lugs 12, extending laterally therefrom and by which said armis pivotally connected to the front end of shaft 7. The arm 11 is provided with a circnlarly-,cLit-away portion between said lugs to receive the shaft 7. (See Figs.y 1 and 3.) The forward carrier or cradle-arm 9 is rigidly secured at the inner end thereof to said arm 11 as shown, to move therewith, and is pivotally connected to con` trol-.bar 10, as shown, and hence said carrier or cradle-arm, and through it said control-bar lO, is controlled and operated by the movement of said'arm 11,

It will be observed that hanger 5 is located adiaeent te the end of: shaft 7 and. that erm ll'is arranged adjacent to. said bracket. A lug` 13, formed on or secured to said bracket 5, serves as an abutment for one of the lugs 12 on Seid arm -ll to limit the movement thereof when rocked iu e direction to roel@ said shaft 7 to elevate the outer ends of the carrier-arms. A projection 11i is formed on orv carried by arm 11 and is adapted to engage the inner edge of breekete for the nurpose of sustaining the swinging arms or cradle in elevated position to receive the bundles of grain. (See Figs. 2 and In order to iaeili'tete the ense-sement of lue 14 with said bracket, I round'the inner corner of said lng,

retaining a fiat outer surface thereof to form the bearing.

In a bearing l5, arranged in any Suitable or convenient? position upon the framework of the machine, but preferably convenient to the seat of the driver or other personererating the machine, I journal a suitable toward the front end thereof is a rod or other suitable connection 17, connecting at its front end with one arm of a bell-crank lever 18. A rod or other suitable connection 19 extends across the front end of the machine and has connection at one end to the other arm of said bell-crank lever 18 and at the opposite end with the upper end of arm 11.

In Fig. 5 I have shown a slightly-modified form of construction for assisting in support ing the cradle or carrier in its elevated position, which in many instances it may be desirable to employ. In this form instead of providing a holding-lug 14, rigid with respect to operatingvarm ll, I pivot a lu g 2O upon said operatingfarm, and to the outer or forward end of said lug I loosely attach connection 19, the lug 20 in effect and mode of operation constituting a leverpivoted intermediate its ends. Any suitably-arranged lugs, as at 21, (see Fig. 5,) maybe provided to limit the rocking motion of Said lng or lever 20 about its pivot, and the rear face or edge of said lug or lever maybe suitably rounded similarly to the construction above described with respect to lug 14,111 order to facilitate the passage thereof past the edge of the hanger or bracket 5,

When itis desired to lower the cradle-arms, as, for instance, when it is desired to deposit upon the ground the bundle of grain, the

IOO

lug 14 is disengaged by the driver suitably manipulating the treadles 1G., whereby the connections 17 and 19 are projected longitudinally, the connection 19 being moved endwise stubbleward of the machine. By reason of the feet that the pvot of. lever 11 is off-Set from the plane of LSeid lever it will be seen that the thrust of connection 19 will tend to rock said lever about its pivot, and hence in a direction to disengage lug 11i from the hanger 5, thereby permitting the shaft 7 to rook or rotate in its bearings and the Cradleerms to be depressed or lowered 'lflre operation of my bundle-earner is eX- ceedingly simple. The parts stand normally in the position shown in full lines in Figs. 1, 2, 3, and f-l. 'lhe sheaves when formed and ejected from the binding mechanism are received in the cradle formed by the arms 8. When the desired number of sheaves have accumulated in the cradle, the driver through the connections described disensases 111s .14 or 20, as the case may be, from the bracket 5, thereby permittingthe shaft 7 to rockin its bearing-s by the Weight of the bundles, or shaft 7 may be positively rocked by the driver suitably manipulating the connections above described, as will be readily seen and understeed, and Whioh may be desirable in ease the grain is too light to effect such movement by its own weight', thereby lowering or depressing the outer ends of the cradle-arms. VVhen't-he outer ends of said arms come in IIO contact with the ground, or, as is most common, when they come in contact with the stubble, as the machine proceeds through the field, said arms are rocked about their pivots upon supporting-shaft 7 into closely-folded position against the side of the machine, thus insuring a discharge of the bundles or sheaves from the carrier and easily riding over the stubble or other obstruction without imposing undue resistance or strain tending toimpede the progress of the machine through the field. It will be observed that the pivoting of controlarm 11 to rock-shaft 7 enables said arm to rock about two pivots intersecting each other at right angles, one of said pivots being the axis of the rock-shaft 7, and hence, in effect, said arm 11 acts as a lever in two directions, the one to rock shaft 7 in its bearings and the other to move cont-rolbar 10 longitudinally to fold the cradle-arms or to distend said arms. By offsetting laterally from the plane of arm 11 the pivot thereof, about which it rocks to operate control-bar 10, it will be seen that a crank action is secured and hence a greater amount of leverage for actuating said control-bar. (See dotted lines in Fig. 2.) Vhen the obstruction has been passed, or when the sheaves or bundles have been deposited upon the ground, the driver suitably manipulates crank 16, whereby a pull is imparted to connections 17 19. In case there is an obstructionof any kind in the way, as, for instance, a bundle of grain or the projecting ends of the stubble offering opposition to the forward swing of the cradle-arms, the first effect of the pull in connections 17 19 is to rock shaft 7 in its bearings and hence to elevate the cradle-arms above the obstructions, and then continued pull effects a swinging of the arms into their normal position. Of course if no obstruction is encountered the first action of the pull referred to is to swing forward or distend the cradle-arms and then 'to elevate them by rocking shaft 7. The construction permitting this result is an important feature of my invention, for thereby the driver is relieved of the severe strains necessary in order to pass an obstruction, an object-ion and defect in bundle-carriers of prior con struction.

Many modiiications and alterations would readilysuggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited to the exact details shown and described.

I am aware of the construction set forth in the patent to Butterfield, No. 362,930, dated May17, 1887; also, Burson, No. 391,451, dated October 13, 1888; also, patent to Goetze, No. 382,603, dated May 8, '1888;' also, patent to Willey, No. 380,968, dated April 10, 1888, and do not desire to be understood as claiming such constructions; but
