Be a known that 1, ,LEANDER J; Macon.

' MICK, ofvOhieago, in the county of. Cook and :State of Illinois, have invented certain newi and usefullmprovementsinAutomatic Grain; Binding Mechanism, ofwhich thefollowing is 'a spe'cification. i 5 1 e The first .partof my invention more 'esp'e; cially relates to that class of automatic grainbinders in which the" bindingwmechanism is mounted upon a traversing carriagaas in the f Well-known Withington binder built by GLYH,"

86 L. J. McCormick at Chicago, Illinois. u f

.In thismachine the binding mechanism is i adjustable to suit the varying length ofgra'in,

sofas always to bind the gavel in the middle by mechanism operated by the driver from his seat,\as shown, for instance, in LettersPatent no. 174,454, granted to said Withingtonl March 7,1876. j

The objects of thisfipart otmy invention are to simplify the construction of this adjust ifng .mechanism, and to adjust .the binding mechanism automatically at the will of the driver by the same power whioh aetuates the y 1 The next part of my invention relates to the wire-supply i n g mechanism of the binder. Its Objects are,'while securing a free delivery of thebinding-wire, to maintain a uniform press ure upon it, notwithstanding variations in the size of the spool upon which itis wound, and also to prevent the wire flying from the spool infcase the wire should break. These ends I attain by combining a wire-spool having pro .1 .jecting axles or trunnions with slotted sup- "lporting arms or brackets'pinwhich slots the trunnions traverse and turn,- a skeleton frame secured upon said arms-beneath thet'runnions. of the sp0ol,,and'a flexible; band stretched across said frame, upon which band the periplie I [cry of the wire coil rests as hereinafter more 1 fully set forth.

Thenext' partof my invention relates to p i mechanism for compressing the gavel betore it isb ounchan'd, more especially, to that fcl ass ofoom'pressorsexerting spring-pressureupon 1 hereinafter more fully set forth.

the gavel.

flhe object of this branch of my impltv mentis' to allow great freedom of movement tofthe spring-arm of the compressor, so asjto preventits binding or straining, which ends Iattain by combining a binding or wirecairryingarrn' vibratin g on a suitable pivotor'support intermediate of its length, a compressing, arm also vibrating or swinging on a suitable support, a slottedribbed head mounted on the heel-extension ofthe binder-arm, a connecting rodor link pivoted on the compressor and i passingfthrough the slotted head, anda spiral Y spring encircling the connectingrod between the compressor-arm and the slotted-liead,as

in the bestway nowknown to me.

T helaccompanying drawings represent all f myimprovements as embodied in one machine ious y, T

however, some of them may be used without the others, and in machines difi'ering some,-- what inthe details of their construction in those herein sh0wn.- l Figural represents a planorftopview of so .niu'ch'of a binding-machineembracing my im. i provementasjisnecessary to illustrate; the subj ect-ma'tterherein claimed, with thebinderarm andcoinpressor elevated. {Fig.2 r p e. sen'ts aside'elevation of the same, and F ig..3

Fig.15 represents averticalsec- .tion. through the wire-spool and its tension on the line 2 2 of Fig. 1. Fig. 6 represents afront View of the binding-a'rm and compressor inflthe act of closing. Fig. 7 represents a vertical longitudinal section, on the line 3 3 of Fig. 8,

through the slotted head in which the connecting or compressor rod slides. Fig 8 represents atop view of the same head, and Fig.

9' represents a transverse vertical section The mechanism is shown as mounted ,upon 1 stout} frame, A, capable of attachment'to' the ordinary harvester-frame in the usual wellknown ways.

An adjustable frame, B C, rests upon this frame and is movable thereon, being held down by suitable hooks b b, embracing the stationary frame A, and prevented from lateral displacement by a guide-rail, b Figs. 1, 2, and 9 I prefer to make the portion 0 0f the adjustable frame, at least, of metal, and provide it with ways 0 0, upon which the reciprocating binder-carriage D slides. A long shaft, E, turning in fixed hearings in the stationary frame A, turns loosely in journals or pipe-box bearings c 0 upon the sliding frame, which is capable of moving freely endwise upon the shaft. A sprocket or other suitable driving Wheel, F, driven in any of the usual well-known ways from the harvester itself, carries a spurwheel, F, which gears into a corresponding pinion, g, capable of sliding freely upon a shaft, It, and controlled by a shipping-lever, G, of usual wellknown construction. A worm, H, mounted upon the shaft h, gears into a spur-pinion, I, turning on a shaft, i, mounted on a suitable bracket secured to the frame. A crank-arm, I, on this pinion is pin-jointed to one end of a link-rod or pitman, J, the other end of which is connected with a stud, a, depending from the adjustable frame 0.

By this mode of construction, when this mechanism is thrown into gear, the crank-arm I rotates and moves the frame 0 backward or forward, carrying the binding-carriage with it,

thus adjusting the wire to the middle of the grain lying upon the platform, and adapting the binding mechanism to different lengths of grain but the adjustment, it will be observed, is made in either direction by the continuous rotation of the driving-shaft in one direction, the direction or length of adjustment being dependent upon the length of time the gear continues to operate.

When thrown out of gear the machine, of course, rests in the position where it is left at the moment of disengagement.

The advantages of this arrangement are obvious, as the adjustment is automatically effected by the gearing, which can readily be stopped or started by the hand or foot of the driver without compelling him to exert his strength to adjust the binding mechanism.

The shaft E is secured to the frame A by means of a yoke-plate, which embraces a collar on the shaft, and thus prevents it from moving endwise, while leaving it free to turn. The removal of this plate permits the shaft to be withdrawn, so that the binding-frame can readily be removed from its supporting-frame. (See Fig. 4.)

Awire-spool, K, is provided with projecting axles or trunnions Ic, capable of turning freely and moving up and down in vertical slots in bracket-arms or supports k, mounted upon the binder-carriage. A skeleton frame, L, is secured upon and encompasses the bracket-arms below the spool-axles. (See Figs. 1, 2, and 3.)

Abelt or strip ofleather, rubber, or other suitable flexible or yielding material is stretched across the frame L in such manner that the periphery of the wire-coil itself always rests upon this band, the reel descendingin its slots for this purpose as the coil of wire diminishes in diameter. The pressure of the wire and its spool upon the belt causes it to sag somewhat and conform to an increased portion of the circumference of H the wire coil, thus creatin g additional friction. A constant friction is thus exerted upon the wire to prevent its paying out too rapidly, and the flying or uucoilin g of the wire, in case of breakage, is also prevented.

A vibrating binding'arm, M, is mounted upon a rock'shaft, M, turning in bearings in the binding-frame, substantially as in the Within gton patent above mentioned, and as shown and described in Letters Patent of the United States of Wm. it. Baker, dated May 22, 187 7 No. 190,096. A heel or arm, m, projecting beyond the back of "the axis of oscillation of the binding-arm, carries a sliding headfln, slotted vertically and provided with inwardlyprojeeting ribs or pins, as shown in Figs.7 and 8.

A compressor-arm, O, swings around its pivot 0 on a projecting portion of the bindercarriage.

A spring-arm or link-rod, N, pin-jointedat one end to the compressor at a point intermediate of its length, passes through theslotted head a above mentioned. This rod is encircled by a coiled spring tending to press it outward in the position shown in Fig. 3. When the compressor and binding-arm are retracted the spring is uncompressed; but when the arm M descends to compress the gavel it compresses the spring, as shown in Fig. 6, and causes the compressor to squeeze the gavel tightly, but with an elastic pressure, while being bound. With the exception of the slotted head, the above-described mechanism for compressing the gavel is substantially the same as that shown and described in the before-mentioned patent of Wm. R. Baker, and is not claimed by me.

By the above-described construction of the slotted head, the spring-rod N is allowedfree angular play or rocking motion therein, as well as endwise movement therethrough, with-. out the necessity of pivoting the head, or causing it to swivel, as in the said Bakers patent.

It is deemed unnecessary to describe in dc tail the other parts of the mechanism, as they form no part of the subject-matter herein claimed, and are, for the greater part, fully shown in Bakers and Withingtons patents, before mentioned.

I do not broadly claim binding mechanism adjustable backward or forward by gearing adapted to be thrown into or out of connection with a constantly-moving portion of the gearing of the machine; nor, broadly, the combi nation of a traction-wheel, shifting binding mechanism, and intermediate mechanism adapted to effect the adjustment of-fthe bind-i ring mechanism by the traction of the wheel;

nor, broadly, the combination of adjustable bindin g mechanism, driving-gearin g, and intermediate connectingmechanism whereby the binding mechanism may besadjusted in either direction by gearing rotating in one direetion; Ibut limit my claim to the specificorganization of the above-mentioned devices, hereinbefore set forth.-

Neither do I claim a traveling binding-carriage carrying a binder-arm upon an overhanging bracket, and gathering and binding the grain as it reciprocates.

Neither do I broadly claim a grain-receiving platform having ways combined with a bindtraverses, the pitman or link-rod pivoted to the adjustable frame, the crank pivoted to the :link-rod, the spur-pinion by which the crank. is driven, the worm-wheel driving the pinion,

and the gearing driving the worm-wheel.

- 2. The combination of the bracket-arms,

self-adjusting wire-spool with projecting axles. resting in slots in the bracket-arms, the skel- 'eton frame secured upon said arms beneath the axles of the spool, and the fiexible band stretched across said frame and supporting the weight of the wire coil, these members bein g constructed and operating as hereinbefore set forth.

3 The combination of the slotted ribbed head n, the spring-rod movingendwise therethrough and having a sidewise or rocking motion independently thereof, the vibrating binding-arm, to the heel-extension of which said slotted head is secured, and the swinging compressor-arm, to which the spring-rod is pivoted, thesemembers being constructed'and operating as set forth.
