GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 366,240, dated July 12, 1887.

Application filed February 15, 1880. Serial No. 191,935. (No model.)

To all whom it may concern:

Be it known that I, LA VERNE W. NOYES, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, which are fully set forth in the following specification.

This invention relates to the compressing and tripping mechanism of a grain-binder, and is shown as applied to a binder wherein the grain is bound standing on end, but-is designed to be applicable to any binder.

In the drawings, Figure 1 is an elevation. Fig. 2 is a sectional plan of the knotter-actuating shaft and adjacent parts in the position of rest, the knotter-actuating wheel being removed to show the parts particularly pertaining to this invention, which lie behind or under said wheel, the compressor-actuating camwheel being broken to show the tripping and clutching devices underneath it. 7 Fig. 31s a similar plan showing same parts in the position just after the binder has been tripped into action. Fig. 4 is a similar plan, the binding-arm being shown in dotted line, the compressor-actuating cam-wheel being unbroken, showing the said wheel, bindingarm, compressor, and trip-lever in the position just preceding the retreat of the compressor and discharge of the bundle. Fig. 5 is a similar plan showing the compressor at the farthest outward position, just at the point of starting back after the discharge of the bundle. Fig.

G is a detail elevation of the clutching device.

Fig. 7 is a detail plan showing the manner of varying the size of the bundle by adjusting the compressor.

- A is the binderframe. (Not shown.) A is a horizontal stem thereof, which sustains the cross-arm A at the end of it, in which the knotter-actuating shaft B is journaled.

B is a shaft deriving power from the harvesterdriving train, and communicating motion to the binder mechanism by means of the bevel-gear pinion C, which is clutched to it at the rear end and meshes with and drives the bevel gear-wheel O, which is conveniently made integral with the compressor-actuating cam-wheel E,hereinafter described, and thesaid combined wheels fixed on the lower end of the knotter-aetuating shaft B.. To afford a bear ing forthe binder-actuating end of the shaft B, there is provided the yoke a having the journal-bearings a a for said shaft, and the fork or box a embracing the neck: or hub c of the gear-wheel 0, (said neck being the connection between the said wheel 0 and the cam-wheel E.) The bevel-pinion O is placed on the shaft B, between the two bearings a a and there provided with means for clutching it to the shaft, hereinafterdescribed. D is the knotter-actuating wheel. It is secured to the shaft B at the upper end of the crossarm A of the frame, being therefore at the opposite end from the cam-wheel E.

To the cam-wheel E is secured one of the dischargers, F, the other being secured, as usual, to the knotter-actuating wheel. ()n the upper side of the caxn-wheel E is pivoted the trip-lever G, whose tooth g protrudes down through the slot 6 in the cam-wheel, in position to engage the clutching device H, which effects connection between the shaft 13 and the bevel-pinion O.

J is the compressor. It is pivoted to the stem A of the binder-frame, and may be, as illustrated, composed of two pieces, J J yieldingly united; and in that case the two parts may be pivoted together at j, and further connected by the rod J secured to the arm J and passing through the eyej on the arm J and provided with the spring J, coiled about said rod J outside the eye j", and stopped and regulated by the nut j at the outer end ofthe rod J It will be seen that the making of the compressor thus in two parts,yieldingl y connected, does not affect its movement in the least; but as the yielding piece is the one which directly receives the pressure of the bundle, this construction merely prevents the pressure and strain of compressing the bundle being too positive, and so allows for some variation in the compactness of the bundle without endangering the machinery,whieh might otherwise, in case of an unusually compact bundle, be subjected to too great strain in compressing. A further advantage of making the compressor in two pieces is that thereby opportunity is gained for adjusting the position of the press ure-arm J 2 to vary the bundle-space, and so the size of the bundle, without change in the compactness. This may be done, as illustrated in Fig. 7, by piercing the rod J with several holes, j into any one of which the pin j may be inserted and form a stop for the arm J By changing the pin from a hole nearer the arm J to one more distant the size of the bundle will be increased. The compressor, however, may be made in one piece, as shown by the dotted line J in Fig. 2, indicating a rigid connection between the parts J and J". The compressor has a stud, j, on its rigid part, by which it is engaged and actuated by the camwheel E. The camtrack is on the upper face of said wheel and comprises the radial part c, the eccentric part 2 and the exterior concentric part 0 i A peculiarity of the structure consists in giving to the trip-lever G an extension, G,

whose rear convex curved edge, G is adapted to form part of said cam-track, being in fact the whole of the eccentric portion or coinciding therewith when in one posit-ion. Said trip-lever has at the vibrating end the spur or hook G shaped'so that when standing in said position its outeredge, g", fills out or forms a portion ofthe concentric part c" of the camtrack, a corresponding portion of the camwheel being cut away, and a stop, as the flange 6", being provided on the cam-wheel to stop the trip-lever in the position described. The trip-lever is stopped in the opposite direction by the hub of the said cam-wheel, as seen in Fig. 3. \Vhen the trip lever is stopped in the first position (against the stop 6) its tooth g is engaged with the clutch-dog of the clutchingdevice 1-1, and holds it and the pinion C out of engagement with the shaft B, and when said lever is stopped in the second position (against the hub of the Wheel E) its said tooth is out of engagement with said clutch-dog, and the latter is engaged and engages the pinion O with the shaft B. When the pressure of the bundle is exerted against the compressor, the abutment j on the latter, engaging the end of the trip-lever, tends to move it from the first to the second position, and so cause the engagement of the clutch-dog with the shaft B and the action of the binding mechanism.

In order to afford proper resistance to the movement of the trip-lever from one stop to the other, the spring G3 is provided, located between said lever and the adj usting-nutwhich forms-the head of the bolt g, which constitutes the pivot of saidtrip-lever. Such spring tends to press said lever down upon the face of the cam-wheel and increase the friction between the said lever and cam-wheel, and by ver against the step e. The latter construction not only provides resistance against motion away from the step 6', but also means for returning the lever to said stop; but this lat ter purpose is positively effected by the engagement of the abutment j with the curved edge Ci of the said lever G, so that the only effective function of said spring G* is the same as that of the spring G"-viz., to resist movement of the lever G away from the stop 0".

The clutching device H is not herein claimed, being shown in detail and claimed in my application filed June 29,1885, Serial No. 170,143. For the purpose of making clear the action of the trip-lever G it may be briefly explained as follows: The shaft B is provided with two teeth or spurs, h it, formed by a fiat bolt set through the shaft, and on the face of the pinion O, which is loose on the shaft, is pivoted the lever or clutch-dog H, which has the projection h from its free end protruding toward the shaft B and in the path of revolution of the tooth y when the leverGis against the stop 6, but outside said path when the lever G is against the hub of the wheel E. The lever or clutch-dog Hhas the abutment (preferably a stud-bearing roll) H, and has a limited play over the face of the pinion -O. At one of its limits (the limit to which it is forced when the tooth g engages its projection h) the abutment I is out of the track of the spurs h h,- but at the other limit (to which it is forced by the spring 11 when its projection h is disengaged from the tooth g) it is in said track. In the latter position the pinion is engaged and driven by the shaft H, and in the former posit-ion it is disengaged and stands at rest.

' The action of the compressor and trip will be readily understood from the above description of the sturucture; but it may be further briefly described as follows: XX X being the outline of the breastplate and bundle-stripper, the position of rest being shown-in Fig. 2 with the compressor protruding past the breastplate into the path of the bundle, when the pressure of the bundle against said protruding compressor is sufficient to overcome the resistance, (whether frictional or other,) offered to the movement of the trip-lever, the latter, receding from'the stop e",disengages the tooth g from the clutching device H, and the binder mechanism becomes engaged with the driving power. This position of the compressor, triplever needle, and compressor-actuating cam is shown in Fig. 3. As the cam-wheel E revolves with the knotter-actuating shaft B, the abutment j travels over the concentric portion 6 of the cam-tracl ,l1olding the compressor in the position shown in Fig. 3 until the abutment is reached by the radial part c of the cam-track. This position is shown in Fig. 4. Engaged by said radial part the abutment travels toward the shaft B, rocking the compressor about the pivot j on the frame, so that when the abutment reaches the inner end of ITO said radial part of the cam-track, as seen in Fig. 5, its point has receded behind the line of the breast-plate, or so far in that direction that it does not impede the discharge of the bundle, which is by that time effected, and while the abutment travels in the eccentric part c of the cam-track back toward the position of Fig. 1 said abutment engages the edge G" of the trip-lever G and forces said lever ahead of it to the position of rest against the abutment e, and restores the compressor itself to the initial position, protruding across the path of the bundle.
