DANKARD H. LUND, OF VATSON, MINNESOTA.

MOTION-REGULATOR FOR SELF-BINDERS.

SPECIFICATION forming part of Letters Patent No. 558,191, dated April l l, 1896.

$erial No. 557,881. (No model.)

To all whom, it may concern;

Be it known that I, DANKARD I-I. LUND, a citizen of the United States, residing at Watson, in the county of Chippewa and State of Minnesota, have invented certain new and useful Improvements in Fly-Wheels or Metion-Regulators for Self-Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in grain-binders which are provided with means adapted to prevent the checking of the power generally incident to the driving-wheel slipping upon or sinking in wet or miry ground without subjecting the mechanism to strain in case the machine is suddenly started or stopped; and its novelty and advantages will be fully understood from the following description and claim, when taken in conjunction with the annexed drawings, in which Figure 1 is an elevation of so much of a grain-binder as is necessary to illustrate my invention. improved friction-clutch which is designed to prevent the sudden stopping of the machine from damaging binding mechanism. Fig. 3 is a transverse section taken in the plane indicated by the line w m of Fig. 2, and Fig. 4 is a plan view of the clutch.

Referring by letter to said drawings, A indicates the frame of a grain-binder, and B indicates the drive-wheel, which is fixed on one end of a shaft 0, which is also provided with a sprocket-wheel D, as shown. Intermediate mechanism,which is only partially illustrated, connects the sprocket-wheel D with the shaft I, which is provided with a sprocket-wheel J, designed and adapted to transmit motion to the chain belt G. This chain belt G passes beneath a sheave a, around a sprocket-wheel h, and over a sprocket-wheel c, and it is designed through the I medium of the said sprocket-wheel c and the shaft H, on which the sprocket-Wheel is fixed, to transmit motion to the usual elevator. (Not illustrated.)

E indicates .a shaft journaled beneath the binder-deck. This shaft E is provided with a sprocket-wheel F,which is engaged by the belt G, and it is designed through the medium of suitable interposed gearing (not illustrated) Fig. 2 is a side elevation of theto transmit motion to the binding mechanism, which it is also not deemed necessary to illustrate.

M indicates a balance-wheel which is fixed on the shaft 1-1. This wheel M is adapted to gain such a momentum that the shaft H, and consequently the shaft 1, will not be affected by the slipping or sinking of the drivingwheel B in wet soil or by the knot-tier en gaging the twine, whereby it will be perceived that the working of the binding mechanism will be rendered smooth and even and will continue, together with the movement of the elevator, even when the movement of the drivewheel ceases momentarily.

In order to prevent a sudden starting or stopping of the machine from injuring the binding mechanism should the machine be stopped suddenly, I mount the sprocket-wheel J loosely on the shaft I, between two collars K, which are splined or otherwise fixed on the shaft, so as to always turn therewith, and provide the said wheel J on each of its sides with two friction-jaws L, designed to' bear against the peripheries of the collars K, so as to enable the wheel J to normally rotate with the shaft. The friction-jaws L are provided adjacent to one end with notches i, (see Fig. 2,) designed to engage the upper and lower horizontal arms of staples N, which are fixed in the sides of the wheel J, and at their opposite ends said jaws are provided with apertures to receive bolts P, which are headed at one end and are threaded at their opposite ends to receive nuts Q and have coiled springs R interposed between the nuts and one of the jaws of each pair, as shown. By reason of this construction it will be observed that either one or both jaws of each pair may be readily removed from the sprocket-wheel J when worn or broken and be replaced by new ones without the aid of skilled labor or any implement other than a wrench, and it will also be observed that the friction between the jaws and collars K on the shaft may be readily regulated to suit various conditions.

It will be further observed from the foregoing that my invention may be readily applied to binders at present in use without the employment of skilled labor, it being simply necessary to fix the balance-wheel on the shaft H and replace the ordinary sprocket-wheel on shaft I with my improved sprocket-wheel J and provide the said shaft with collars, as K.

Having described my invention, what I claim is In a grain-binder, the combination of the main frame, a drive-Wheel, a shaft E, provided with a sprocket-Wheel F, and adapted to transmit motion to binding mechanism, a shaft H, for driving an elevator and provided with a sprocket-wheel c, a balance-wheel fixed on said shaft H, the shaft 1, connected with the drive-Wheel and provided with collars K, the sprocket-wheel J, loosely mounted on the shaft I, between the collars K, and having staples N, on its opposite sides, friction-jaws presence of two witnesses.
