HARVESTER-BINDER..

SPECIFICATIGN forming part of Reissued Letters Patent No. 10,106, dated May 9, 18672.

Original No. 242,177, dated May 31,1881. Application for. reissue filed April 121, 18.62. Y

To all whom it may concern:

.Beit known that I, WILLIAM R. BAKER, a. citizen of the United States, and aresident of Uhicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvester-Binders, ct' which the'following is a. specification.

The invention relates to that class of binders in which the gavel. is automatically seized and bound, and more particularly to the type represented', for example, in Letters-Patent ot the United States to John F. Appleby, dated February 18, 41879, No.212,420. In this special type packing arms or fingers are arranged usually below the chute-board and operate through slots therein to pack or compress thegrain into a receptacle preparatory to binding.v At the bottom of the receptacle the grain is received and partially supported upon pvoted fingers or bars, against which it is pressedby the packers in the formation of the bund-le, and when suicient grain is so compressed to form the bundle the force against the linger-s causes them to rocker move backward a short distance. In making this backward movement the lingers are arranged to trip and setin motion the machinery which operates the binding-arm, and also, in some cases, to stop the packers while the bundle is beingbound and discharged. Said fingers are carried upon or near the free end of a hinged bar or rod which swings or yields downward beneath the ,table orchute-board to withdrawthe fingers from the path of the sheaf at the conclusion ofthe binding operation andI permit it to be kdis/charged.

My invention has reference to the mode ot' supporting this bar or rod to which the trippin g-ngers opposing the packers are pivoted ;4

and itconsists in the provision of means whereby said bar is rigidly locked against downward play or yielding until the binding mechanism Y has been tripped by the action ot' the lingers, and in the special combinations hereinafter pointed out and claimed.

In the drawings, Figure 1 is a longitudinal section of the chute-board, through the slot in which the binding-arm operates, 'showing a side'view of the binding-arm and one of the supporting-ingersin the position which these parts occupy when the packers are in opera-A tion as Fig. 1, with the parts shown in 'the body of the'arm.

tion. The dotted lines show `the backward position of the lingersand'the elevation ot' the trip-lever. Fig. 2 is a view on the same sccthe operaton of bindingand discharging the bundle, the dotted lines showing the position of the lingers when the bundle is being discharged. Fig. 3 is atop or plan view of the parts shown` in Figs. l. and 2, without the chute-board, and having the operatie g shafts broken away. Fig. 4 is a view ot' one of the shafts detached. I

Like letters of reference refer to like parts throughout the several views.

A designates the chute-board; B,'thc binding-arm; C, the trippingtingers, which stand in the machine opposite to the packers, which are not shown.

Dis a portion of the supporting-frame ofthe machine.

The chute-board is 'arranged npouthe harvester at an incline of about twenty degrees (more or less) from a horizontal, with its elevated end next to thegrain-elevator of the harvester, so lhatthe graines it falls will be caught thereon and will slide down toward the.tripping-lingvrs and be stopped by them.

E designates the` bar-or rod to which the tripping-fin gers are pivoted by a pivot, This e,'tixed on the bar and passing through the eye. Thebarisjsupportediutheposition shown in Fig. l by a spring, b", acting through shaft b and cranks Nba-and pitmanrod b against The machinery is'trippedby the grain pressing the finger U back to theposition shown in dotted lines, Fig. 1. rocks 011 pivot e and elevates'` the projecting lng a? on the bottom of the finger, which raises the tripping-lever a', attached to shaft 3. The binding-arm is operated by a rock-shaft, a, set in motion, as is ,the remainder ofthe interme diete-binding mechanism, by the tripping of the clutch'through these instru'mentalities. A

All'of the parts as thus illustrated and described are'not materially diierent from those well known in the class of machines to which reference is made.

In all machines of this class the bar ,or rod In doing this the finger' bar is hinged to a heel-extension of the binding-arm by an eye, c2, on said. arm and a pm,

E,- which carries the ngers which cause the grain is damp or green, and from other causes,

that the pressure of the grain against the bottom of the tripping-tingers will cause the spring-support to yield before the pressure at the top of 4the fingers is suicient to canse their backward or rocking movement upon their pivot. The yielding of the springin this manner allows that end of the barE to which the fingers are pivoted to be borne down and lowered in its position, so that the backward movement ot' the lingers, taking place after such lowering, will not elevate the trip-lever, and hence the binding mechanism will not be started, nor where the packers are to be stopped will they be thrown out ofaction', andthe mnchine will clog. To avoid this diiicult-y and remedy the defect I lock the supporting-bar positively against descent until the tripping movement of the lingers takes place, for this purpose making the hinge between the bind-- ing-arm or its rock-shaftl and the finger-support E such as to support this bar in the posi tion shown in Fig. 1, irrespective of the springsupport-that is, the hinge is` made entirely rigid at this ',poiut, so that it will not allow the other end ofthe bar to drop any lower, whether it has or has not other support. This rigidity of the hinge at tlie'point desired is best secured by means of a pin or lug, c, upon the bar E, and a lip or projection, c', upon the eye c, arranged to meet at the point desired and prevent any further tnrning'oi' the hinge.a v This aords a reliable support to said bar, and

insures the tripping of the mechanism under all circumstances. As soon as the fingers have operated the trip, the binding-arm starts upon its upward movement, thus breakingA the lock by carrying the lip c away from thepin c, and the bar is'free thereafter to be lowered at the proper moment to allow the discharge oi' the The return of the binding-arm bound bundle. d t0 its'lirst position renews the lock at the moment the clutch is thrown out, and the parts will be again ready for a fresh binding operation. v

I claim as my invention-.-

1. In a grain-binder, the combination, with the grain-receptacle and supporting-bar which carries theA tripping-lingers, of locking mechanism which holds said bar positively against movement away from the receptacle until the Y trippin g-iin gers have started the binding mechanism.

2. Ina grain-binder, the combination, with the trip-lever, the yielding tripping-iin gers, and the spring-supported bar which' carries said fingers, of locking mechanism which positively Astops the arm from yielding against the stress ot' the spring until the trip-lever has been actuated by the lingers..

3. In a grain-binder, the combination, with the vibrating binding-arm, the tripping finger or ngers, and the supporting-bar which carries the latter, ot a hinge-connection between 1said binding-arm and supporting-bar rigid in one direction, whereby the bar isloeked against yielding or sagging when the bindingarm is down.

4. In a grain-binder, the combination of the trip-lever,the trippin g-n gers, the supporting- .bar which carries the latter, the vibrating binding-arm, and a hinge-connection between said binding-arm and supportingbar adapted to lock the latter against yielding away from the/grain-receptacle until the trip-lever has been actuated and the binding mechanism started. f

5. In a grain-binder, a support, E,- for the compressing and tripping fingers C, hinged to the binding-arm, in combination with a pin, c,

on support E, and a lip, c,on the bindingarm, all arranged to operate substantially as and l'or the purpose specified. Y
