"UNITED `SYLVALNUSJ). LOCKE, OF JANESVILLE, YWISCONSIN IMPROVEMENT IN GRAIN-Brunes.

Specification forming part of Letters Patent N o. 97,536, dated December 7, 1669.

.To all whom vit may-concern: y y y ,Y y

Be it knownA that I, SYLvANUs D. LocKE,

of Janesville, Rock county, State of Wisconsin, have invented certain new and useful Im-` provements in Grain-Binders; and I do here- `bydeclare that the following is `a-full, clear,

and exact description thereof, reference being `had to the `accompanying drawings, making a part of this specification, in which,-

V Figures 1, 2, and' 3are side views, showing one mode of constructing the mechanism ,for

operating my improvement, together with the different positions which it and the` bindingwire assume during the operation of binding. Fig. Asis `a front lView of my improvement.- Fig. 5 is a horizontal section of the saine.`

Figs. 6, 7, and 8 are rear views of the same, showing the difterentpositionsof vthe several parts, and ,of the binding-wire, during the op-l eration of binding. Fig. 9 is au elevation, in detail, ot' the ,rotarylpart of the cutting mech anisin.' Fig. 10 is an elevation, in detail, of

the fixed part of the cutting mechanism.

Figs. 11 and 12 are sections of the cutting and holding mechanism, showing how the bindingwire is cut and the end held. Figs..13 and 14 are underside-views of my improvement as it appears-when operated, asl shown in Figs. 1, 2, and 3. Fig. 16 isan elevation, in detail,

of the rotarypart of the wire-holder; andk Figs. 15, 17, and 18are sideviews, witha section of the` inclosing shellsupport of ymy im- 1 provement, showing the` dilerentpositions` of l the several parts, and lof ,the bindings/ire,`

during the operation of binding.

l The nature of my invention consists, rst, in A' the employment, on a 'grain-bindin g machine, of

anyfpinion for twisting together the two ends of the binding-wire, lafter `the same havevbeen thrown around 1 the bundle, the ends forthat `purpose y being thrown directly into the. teeth of the pinion; secondly, in so constructing the irotary twisting devices of grain-,binders that the twisting-pinion shall `take bearing; only upon the ends or faces of its teeth, thereby dispensing-with the shaftor ordinary bearingsat its ends, andenabling Ait to f beused particularly described.

're enable others skilled in heart 'to make.

and use my invention, 4I will proceed to .de-

scribe its construction and operation.

In the drawings, Figs. 1, i2, and 3 are vintroduced to show one Inode of operating ,myinvention, and therein A and A' represent camarms that are pivoted at w, and .that operate, respectively, the twisting-arm Fand the binding-arm E. On the twisting-arm is acircular rack, G, playing in a pinion attached to vthe gear-wheel H, that turns on the stud P on the arm E. -To the arm E'is attached the Vsegmental gear B thatplays in thesegmental pinion C that is ,pivoted at y, and'to-which is attached the third` arm D. J is' a grain-guard K, the binding-platform; M, the reel, lforbearing the binding material; and L the bindingwire. All are actuated by thecrank Iv that plays-in Vthe cam-grooves c cin the cam-arms A Aand A. v y i V y, n The form of the cam-grooves is such as-to give to the arms F E D the movements herevinaftel describedi V c Y, i

The twisting-pinion A may be abevel or spur pinion, but is here shown. as a bevel-pinion.

`It takes bearing only upon `the ends of ,its

teethin the parts d f' of the inclosinggshell, which parts are attached together by screws', as shown, or otherwise, and secured,inany' suitable manner, tothe hand e of the binding- Yarm E. The formof this shell i'ssuchas to leave both ends of the p niou and the lower portion of theteeth fully exposed.

Thetwistingpinion is operated by thefgear'- wheeLH, and has firmly attached to its outer end, by rivets or otherwise, apart, m, more fully shownin Fig. `10 that is,`as.to tsedge, a vstationary knife, against `which the radial blades n, it', n, and u, of the rotary part of the cutting device, more ffully shown in 4llig. 9,.alternatelywork,lafter"themannerofshears, to cut or sever the wire, and which, as y to its side face, is `a `stationary jaw, againstwhich the radial arms g, g', g'y', and g, of the rotary part of the wire-holder, alternately press lthe binding-wire, so as to thereby hold thecutor free end. j y y,

IThe `circular bodylof the rotarypart of ,the

Wire-holder is recessed, lasshown more` par,- `ticnlarlyin Fig. 16, to receive the `circular body' 0f 'the rotary part O'f fhewifefcuttiils devicewmf, n, and n, andintowhich re` cess the latter is 'soj'ar Ainsertulastio. leave between the radial arms g, g', g, and 9",iand

t h k, that passes longitudinally through the pinion, as shown, and that, by means of its nutj, holds them firmly together, and pressed against the stationary part m.

On the face of the gear-wheel H isa dog, r, Figs..13 and 14, that ispivoted at t, and that is heid by the spring 's against the lug or projecting portion u of the wheel.

The pin p, passing through the pinion 'i and the bolt h k, is used to prevent the pinion from turniugon the bolt, and so loosening the nut j.

The boltk k gives bearing tothe rotary parts aforesaid, and allows the latter to be readily adjusted by means of' the nut j and the use of washers between the parts, at any desired distance from the fixed part m, so as to permit the use of any desired size of wire.

When in operation the crank I, revolving in the direction shown by the arrow, and the various parts being in the position shown by Fig. 1, the end of theV binding-'wire L is carried from the reel M, on or along the arm D, as shown in Fig. 1, and then, being taken into and through the mouth Vo ofthe shell df, and between the teeth t of the pinion t', and placed around one of the radial arms, g', of the rotary part of the wire-holder, it is inserted between another radial arm, g, and the stationary part m, as fully shown in Figs. 1, 6, and 15.

rlhe crank turning, as indicated, the arms D and E open or separate to allow the rbundle to be brought in on the platform 7c against the guard J, when, the arms closing, the bindin g-wire is looped, L', around it, and again inserted in the teeth z" ofthe twistin g-pinion t', as shown in Figs. 2, 7, and 17.

- The form of the cam-grooves c c must be like that shown in the drawings, so as to cause the two ends L L of the wire passing around the bundle to be inserted in the teeth on the gear-wheel H that, in turn, causes the twisting-pinion i and the attached wire-holding and wire-cutting mechanism to rapidly revolvo, so twisting together the ends L L of the wire, as shown in Fig. 18.

The position of the wire-holding and wirecutting mechanism, with their operating-dog r, is shown in Fig. 13. During the latter part of the twisting-operation, the movement of the gear-wheel H, in the direction indicated by the arrow in lastlnamed gure, carries the free end of the dog fr underneath the revolving radial arms g, g', g, and g', in such a manner as to strike and drive backward one of the radial arms, g', to the position before occupied by the arm g.

The relative position of the wire-holding and wire-cutting mechanism, and of the binding-wire, before this latter movement of the rotary part of the wire-holder, is shown in Figs. 7 and 17, and their relative position after (this movement is shown in Figs. 8 and 1S.

The movement of the radial arms is backward only relatively to the revolution of the twisting-pinion, as the real eiiect of the dog o' is simply to stop the movement of the rotary parts of the wire-holding and wire-cutting devices until the movement ofthe twisting'- pinion shall carry forward, over one of the spaces between the radial arms, the fixed part m. f

The backward movement or stopping of the rotary parts of the wire-holding and wirecutting mechanism, in causing the radial arm g and radial blade um, Figs. 7 and 17, to take the position, relative' to the fixed part m, respectively shown by the arm g and blade n", in same iigures, thereby rst drives the.

arm g alongside of the iiXed part m,and forcibly doubles between them the end L of the wire, as shown in Fig. 11, and then the blade n", following, cuts it off, as vshown in Fig. 12.

The same movement that causes the arm g to seizeand the blade n to cut oii the new end L", also causes the arm g" to release the old end L, as shown in Figs. 3, 8, and 18.

After the wire is twisted, seized, and cut oft', as above described, the crank- I, running out ot' the upper cam-groove in the cam-arm A, to its first-described position, causes all of the parts to assume the position shown in Figs. 1, 6, and 15, when the bundle can be removed and the operation repeated.

As thev gear-wheel H runs back, carrying with it the dog r, the form of the latter is such as to enable thearms y, g, g, and g to swing it inwardly von its pivot, as shown by dotted lines in Fig. 14, without themselves being operated.

As the dog passes the arms it is driven back by the spring s. f Y

What I claim is- A The central bolt h 7c, when used to hold and adjust the rotary parts of the wire-holding and wire-cutting mechanism against the face of the fixed part m, substantially as described.
