GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 495,044, dated April 11, 1898. Application filed November 3 1890. Serial No. 370,209. (No model.)

To all whom it may concern:

Be it known that I, MAURICE KANE, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois,

5 have invented a new and useful Improvement in Grain-Binders, of which the following is a specification.

This invention relates to machines for binding grain and its object is to increase the efi fectiveness, and particularly to simplify the construction of the binding proper.

'It consists in the construction and arrange ment hereinafter described and claimed. 1 Like letters refer to the same parts in the several figures of the drawings.

Figure 1. is a side elevation, looking from the front of the machine, of the compressing finger and the devices for operating the same,

Fig. 2. is a similar view except that the devices are in position to begin action. Fig- 3. is a similar view except that the devices are shown as having acted to release the compressing fin- 2 5 ger. Fig. 4.. is alongitudinal section on the line 12-12 Fig. 1, and looking from underneath. Fig. 5. is a detail view in front elevation of the gearing and connections for com municating motion from the packer to the knotter o driving shaft. Fig. 6. is a side elevation of the same. Fig. 7. is a side elevation of the devices shown in Fig.1 looking from the rear of the machine. Fig. 8. is a detail view of the pivoted dog, as applied tothe wheel. Fig. 9

3 5 is a detail view partly in section of a portion of the shaft and inclosing housings and the needle arm and sleeve for the projecting toe arm keyed to such shaft.

I will now describe the gearing and the de- 4o vices for communicating motion from the packer shaft to the knotter shaft. In a common form of grain hinder the packer shaft rotates continuously, but the knotter driving shaft is only rotated at intervals or when a mechanism,

' sufficient quantity of loose grain has been gathered and compressed to constitute a bundle, and it is customaryat this last mentioned stage of the operation for the pressure of the bundle to trip a stop and set the knotting 5o mechanism in operation. I design to employ this usual mechanism and make no claim thereto but my invention resides in the arrangement of gearing for directly connecting the packer shaft tothe knotter driving shaft and the combination therewith of devices for coupling and uncoupling such gearing.

Referring to Figs. 5 and 6 of the drawings L designates thepacker shaft which is continuously rotated preferably by a belt or chain connection with the harvester or in any 50 other suitable manner and carries upon its outer end an arm Z provided with lugs upon its inside face as is usual. A part L, of the. frame, supports housings for the packer shaft and for the knotter driving shaft L and a shaft L is also supported by a bracket from this frame and carries at its lower and upper ends respectively the bevel gears L and L. A bevel gear L is rigidly mounted upon the knotter driving shaft and meshes with the bevel gear L". A bevel gear L is loosely mounted upon the packer shaft and meshes with the bevel gear L. On the outer face of the bevel gear L is pivoted a dog Z and a" small spring tends to throw one wider end ch7 the dog into the path of 3. lug on the inside of the arm Z but is normally prevented from j so doing by the con-tact of the longerand narrower end of such dog with the stop arm Z arranged uponthe needle shaft. When how 8o ever, the bundle becomes of the proper size to require binding it trips the stop in a well known manner andjzthe small spring under the dog then throws the latter into the path of a lug on the rotating arm Z and consequently such arm causes the bevel gear L to rotate with it and to drive the knotter driving shaft, through the other bevel gearing. The stop arm is by another spring thrown into position to contact with the dog and 9c thereby arrest the motion of the gearing driving the'knotting mechanism, as shown, as the bundle is bound. Z, designates the bolt for connecting to the bevel L the socket L which is secured by the pitman Z to the crank 5 on the needle shaft; but as these form no part of my present invention they will not be further described. Theabovedescribed meohanismisextremely simple, considering the purpose in view, and is direct and efiective, in its action.

The next feature of the present invention which will be described relates to the devices for operating the compressing arm and reference is made to Figs. 1, 2, 3, 4, and 7, of the drawings for an illustration thereof. 0 designates the needle arm which is mounted upon the shaft 0. Adjacent to the needle and upon the same shaft is rigidly secured the arm, 0, which has a lateral projecting toe, s. A sleeve or rather a housing a is secured to the frame and affords a bearing for the needle shaft which housing has a depending bracket which latter supports a bent bolt v. Two curved bars 0 and O are pivoted at their inner ends upon this bent bolt and the lower ends of such arms or bars are connected by a longitudinal bolt to one end of which is piv= oted to the bar 0 and the other end of which passes through an aperture-in the end of the bar 0 and is. provided with a limiting nut. This sleeve or housing may be divided as shown so as to allow the hub of the needle arm and of the projecting toe to rest' upon andbe fixedly secured to the shaft. A spiral.

spring 0 encircles the bolt w, andisconfined between an adjusting nut and the end of the bar 0 through which thebolt passes. Rig-idly affixed tothe bar 0 and projecting vertically therefrom is the compressing arm- 0 which arm is designed to present a bearing surface against which the needle arm and packers may press the bundle of grain, and as the bar 0 is free to slide on the bolt 00, against the spring the compressing arm affords an elastic bearing surface.

Extending from the sleeve or housing before referred to is a bracket 0 carryinglugs,

in which is pivoted a latch 0 which pivot is designated by the letter 0 Projecting from this bracket 0 is a bolt b which passes: through the latch and cam finger 0 The cam finger may turn upon the bolt and has; a bent or convexed outer end 0 clearly shown in Fig. 4 of the drawings. A spiral spring 0 end secured to a washer at the. upper end of the bolt and itslower end resting upon the topsurface of the cam finger whereby the. latch is normally pressed inwardly and the spring has its lower coil extended as, at 0, and hooked over the upper side of the cam finger so as to normally pull the said finger downward, an elongated slot being made in the latproj ectingfrom latch 0 and extendingthrough the cam finger 0 The brackeho", has a slot through which the latch may pass, and, when the parts are at rest, the extension, 0 of the compressing finger, 0 thereby held in an upright position. The bar, 0 has also a stud, 0', projecting from its inner side forward of its pivotal point. The operation of these devices will now be set forth. Ordinarily the latch and as the compressing finger is attached to bar 0 which is connected to the surrounds the bolt with its upper bar, 0, said compressing finger is held in an upright position. In thisposition the compressing finger affords a bearing surface againstwhich the packers and the needle arm press the grain. When the needle bar is in its normal position, as is shown in Fig. 1., the

' bars, 0 and, O and compressing finger, O

are supported by the latch,but as the-needle moves up it carries the arm, 0, and its toe with it and such toe rides underneath the bent end of the cam finger and causing the same to turn on its pivot b, it pushes it out of the way and finally assumesa position above it as is shown in Fig. 2, of the drawings.

-After the needle bar has done its work, it goes back and carries with it the arm, 0, and its toe; over the, convexs-u-rfaceof the bent or curved f end of the cam finger and thereby depresses ithe same and withdraws-the latch from under the com-p ressing bar or rather its. attached ibar, when these several bars will fall out of ithe way and permit the bundle; to be dis- ;charged. The parts will then be, in the pcthe latter is caused to strike and pass .sition shown 1n Fig. 3. As the. needle bar moves back to its original position, it bears upon the'stud, 0', and forces the bar,O and its connecting bar, 0 and the compressing finger, 0 up into position for action in connection with the next bundle, where they are held by the latch as before mentioned.

It is obvious that,.=a skilled mechanic may make many modifications: of the details of this invention, without departing from the spirit thereof, and I therefore, wish it to be understood that I do not desire to limit myself to the exact construction shown and described.

What I claim, and desire to secure by Letters Patent, isv 1. In a grainbinder the combination of a constantly rotating packer shaft having a clutching device affixed thereto, and a bevel gear loosely mounted thereon forengagement with the clutching devices at suitable inter- ;vals; of a knotter driving shaft having a bevel gear upon its end,- a shaft. intermediate of the knotter driving shaft and the packer shaft having bevel gearsat each of its ends i which respectively mesh with the bevel gears of the other two shafts; substantiallyas and for the purpose set forth.
