SPECIFICATION forming part of Reissued Letters Patent No. 9,735, dated May 31 1881 Original No. 74,454, dated March T, 1876.

To all whom it may concern: Be it known that 1, CHARLES l). \VrrIuNG- TON, otJauesvillc, in the county ofltock and Stateot' Wisconsin, havehwented certain new and useful Improvements in (iraiu-Bh-uling Mechanism, of which the following is a speci tication.

My invention more especially relates to antomatic binders ot' the class having a binding orwirecarrying arm moving in a circular path and mounted on areciprocatingcarriage; and my said invention consists of certain new combinations and organizations of devices, which are set; for-that the close of this specification. In the accompanying drawings, which'show the best way known to me of embodying my improvements previous to the date of my ap plication for the'original patent, Figure 1 represents a view, in elevation, of so muchot' my improved apparatus as is necessary to illustrate the invention herein claimed, as seen from the rear, with the parts ,in the attitude theyassume when the compressing and binding arms are closed upon the bundle. l- Fig. 2 l

Fig. 5 represents a, vertical longitudinal section through the bind, ing mechanism beneath the platform; Fig.6, a view, in perspective, of thepositive stopmotion feed for the lower w'ir a-spool; Fig. 7, a View, 'in perspective, of the snaiLc-ani or actuating-wheel for adjusting the binder-frame on its ways; and Fig. 8 a view ol'auotlna portion 01' said adjusting mechanism, showing the A m'ilieation for reissue liled July 3, 1890,

details ot'its connection with the binding-ina- 5o chine. i The binding mechanism is, by preference,

mounted on a suitable frame, A, secured upon the frame of a harvester of any suitable well-v known construction,having an endless apron '55 toi elcvatingand. delivering the cut grain into a suitable receiver, as in the well-known automaiic binders ot' \Vatson, Renwiek, and \Vatson, Carpenter, and h'lcUormick.

The grain is delivered from the elevatinfgkGo apron,through an opening in a gallows-frame, A, which constitutes a fixed part of the liar vester-l'rame, upon a slatted inclined receptaele li, forming anexlension of thebinding platform I). i I I 6 5 In order that thewiremay be passed around I the middle of the bundle, notwithstanding va-' riations in the length of the grain,Imountthe frame A of the binding mechanism upon ways U U, which permit'it to be moved freely backward and forward in a line parallel with the length of the'grain. The bindingmechanism is driven bycranks,

-sprocket-wineels, or gearin'gactuated by any i suitable prime mover, C, turniu I'rame in order to accommodate the adjustment of the binding mechanism above mentioned, the shalt U is arranged parallel with the line of adjustment of the binder-frame, and, in fact, in thisinstance constitutes one of the ways upon which said frame slides, and the double gear 1) l),- by which the binding mechanism and mounted on a shaft, 75 g in fixed hearings 'on the harvesteris actuated, is likewise so constructed as to be free to move endwise on the shalt (while coin; pelled to turn with it) by the usual spline or feather This gear wheel revolves between jaws of the bimler-trame, which keep it in proper relation to the gearing driven by it.

- in order to place the adjustment oithe bind-' iug mechanism under the control of the driver while inhis seat on the machine, 1 mount the shifting mechanism 'upon the gallows-frame A, which constitutes, as before stated, a fixed 5 portion of the liarvcster-lraine. This shifting mechanism shown consists of a turning-shaft, E, provided at its upper end with a crank or handle, e, to turn it, and at its lower end with a snail-wheel, c. Said wheel 6 works in or meshes with the teeth of a slidingrack-bar, F, connected with the binding mechanism by means of a jointed" connection consisting of a link,j', jointed to a lever, F, fulcrumed on the frame-piece A at f, the lever being, in turn, jointed to a link, F connected with the sliding binder-frame. By this mode of construction the driver can readily shift the frame to bring the binding-wire to the middle of the length of the bundle by turning the crank or handle a, which is constantly maintained in a convenient relation to the drivers seat, the shiftingcrank being preferably rendered incapable of movement upon the harvester-frame other than in a horizontal direction, which capacity is given it in order to turn its shaft and the act uating-wheel carried by it to shift the binding mechanism.

By means of thejointed connection between the rack-bar I and the'binder-frame I am enabled to employ a rack-bar to shift the bindertrame without danger of cramping or binding the shifting mechanism.

The binding platform or receptacle 1 it will be observed, is mounted upon and adjustable with the binder-frame, but is stationary relatively to the line of reciprocation of the binding-arm of the machine, the reciprocation .or

movement of said binding-arm being in a direction crosswise of that in which the binding mechanism is adjustable to bind the bundle of grainat the proper point. 1

A grain-deflector, G, mounted on or con, nected with the receptacle or platform B, slides in guides on the frame-piece A of the harvester, above the opening in said frame through which the cut grain is delivered, and is thus kept in its proper relation to the other parts, being adjustable with the binding platform or receptacle B and the binding mechanism relatively.

to the elevating and delivery apparatus of the harvester;

It will be noticed that the shifting mechanism above described is common to the binding mechanism, the deflector, and the binding platform or receptacle, so that all may be shifted or adjusted simultaneously, which construction is preferable, as it preserves the proper working relation of the parts.

The binding mechanism, in most of its dctails, is similar to that shown'in an application for Letters Patent of the United States filed by me March 5,1874, and patented 'J anuary U, 1877, as-No. 186,180, and therefore nc d not here be described in detail. I

A double sprocket-wheel, I), mounted upon the drivingshsft 0, gears into corresponding wheels H,over which the driving-chai n I passes, as well as over corresponding wheels, 11, on the opposite end of the slotted box-frame J, described in my patent above mentioned.

The driving-shaft G revolves in the direction indicated by the arrow in Fig. 1, and, by means of a slotted link, I, hooked to the driving-chain I and connected with a shaft, L, mounted on a frame or binding-carriage, K, which carries the standard M of the binding-arm, imparts a and said binding-arm.

litmen N N, pivoted on the crank l of the shaft L, are respectively attached to the cranks 0 p of two roek-shal'ts, O I, concentric with standard or support M of-the binding-arm. (See Fig. 3.) The inner rock-shaft,O,'- consists of a steel rod, and carries at its forward end a crank-arm, 0', working in a slot of a vibratjecting portion of the binding-arm frame so as to give the compressor a movement eecen tric to that of its driving-shaft 0, which shaft, owing to the construction above described, conslightly under any excess of pressure over the normal strain of binding the bundle. I do not claim, however, the adjustablecrank and ecvices being the invention of,Wm. It. ak'er, of Chicago, Illinois. l

The binding or 1 wire 4 carrying arm S is vibrates concentricallywith it.

Ina machine organized (as mine is) for the use of two wires, or even for the use of a single wire, it is highly ad vantageous to press the wire into the twister with a positive force applied on each side of it. In order to obtain this desideratum, I have heretofore used a bifurcated arm; but as I find it advantageous to give a piercing action to the point of the binding-arm, while obtaining the advantages above mentioned, I now form a vertical longitudinal slot in the binding-arm, "and pivot at proper ntervals by means of a pin on its inner end aking into a cam-groove, t, on the tubular support M of the binding-arm, as shown in r FigA. The organization of these parts is such that as the binding-arm moves forward into the inflowing grain to separateit the point of the supplementary arm isinclosed within the bimling-arm, as shown in Fig. 2, so as not to interfere .h the piercing action of the latter in separating the grain; but when the arm has passed around the bundle as it is compressed the forward end of the supple mental-y arm is thrown inward by its cam, as, shown in Fig. 4, and the wirc is held secin'ely in proper relation to the twister, V

The construction and operation of the bind.

shown in my application of March 5, 187 4, and patent granted thereon, as aforesaid, need no substituted a positive feed for the wire-supp] ing device shown in that application. To th end I mount npon the intermittingly-rotating shaft L a stop-whcet U, having a single tooth,

mounted on the rock-shaft P, and, of course-,g

.therein att asu )lcmentar arm T vibrated ing-head and twisting mechanism Z, and its actuating sector-rack Y, being similar to that 125 reciprocating motion to said bindingcarriage each other, and inclosed within the tubular hag compressor, It, pivoted at r on some prostitutes a torsional. spring, allowing the com- 8; pressing-arm and its driving-crankto yield centric compressor above described, ,grese departicular description here. Ihave,however,

a, which revolves in the direction of the arrow shown in Fig. 6, and gears into a corresponding wheel mounted upon the wire-reel V, and provided with teeth o, arranged in four sets orpairs,thusintermittinglygivingofl'adefinite amount of wire, regulated by the size of the drum and the position of the teeth. The slack of the band is taken up by the intermediate take-up tension-drum \V of the upper wire,

which is shown as passing over a pulley, w, on an arm projecting from the binding-arm standard, so'as'to bringitin proper'rclation with the binding-head.

Theoperation of the mechanism, being substantially similar to that shown in my patent above mentioned, need not be particularly described, only so far as to illustrate the peculiarities of thedevices herein claimed.

The grain is delivered continuously by the endless apron upon the biriding-platform B. In Fi 2 the parts are shown in full lines in the attitude they assume at the momentot' the discharge of the gavel. The binding-arm then moves forward to the position shown in Fi 1 and pauses while the stirrup-link l is turning with the chain around the-sprocket II which turns the shaft L, causing its crank l to act through its pitman upon the binding-arms R S, causing them to descend upon and compress the bundle, and carries the wire into the binding-head, as shown in Fig. 4. .The arm then moves backward to the position shown in Fig. 2, twisting and severing the wire as it goes, and the binding-arm and compressor retract from the position shown in dotted lines in said figure to that shown in the full lines, leaving the bound bundle upon the platform to be shovedotl' by the succeeding bundle.

The positive feed of the lower wire takes place during the retracting movement of the binding-arm and while the binding carriage is stationary.

1 disclaim herein, broadly, the combination of the binding-plattbrm, the deflector, aud tahc binding mechanisn'i, all mounted upon a com mon frame adjustable relatively to the length of the grain. This combination constituted the subject-matter of the first clause of the claim ofmy original patent; but since the grant of said patent I have discovered that the said combination, broadly considered, is not original with me. have also discovered, subscquent to the grant of my said original patent, that the validity of its second claim is also a matter of grave doubt, said claim being di-' rected to the combination of the reciprocating binding mechanism, the frame upon which it is mounted, the ways on which the frame traverses, l he drivinggearing of the binding mechanism' mounted on one of said ways, the shifting-gearing mounted on the main framc,'and' the link-conncctions between the shifting-gear ing and the traversing binding-frame. The third claim (now fifth) of my original patent is also stated in inaccurate terms. i' believe myself, however, to be the first 'l originat inventor of thecombi nations and organizations recited in the following claims, which are directed to subjects matter hi ghl yuseful in grainbinding machinery.
