RICHARD H. MOORE, OF WAKITA, OKLAHOMA.

GRIPPER-DISK FOR BINDERS.

Specification of Letters Patent.

Application filed November 17, 1914. Serial No. 872,604.

To all whom it may concern:

Be it known that I, RICHARD H. Moonn, a citizen of the United States, residing at Wakita, in the county of Grant and State of Oklahoma, have invented a new and useful Gripper-Disk for Binders, of which the following is a specification.

; The present invention appertains to knotting mechanisms for binders, and more par ticularly to a twine gripper or holder.

Vith the customary twine gripper or holder now employed in the knotting mech- "anisms of binders, the notches of the disk become rounded and smooth due to the wear and friction after continued use, which not infrequently renders the gripper inefficient or inoperative, since the twine hook will not properly hold the twine in the notches of the disk.

This invention contemplates the provision of a twine gripper or holder so formed, as to continue in its efficiency, notwithstanding the fact that the gripper becomes worn away in the continued use to which it is subjected, and whereby the common grippers or holders may be readily altered in accordance with the present invention, to increase the life and efiiciency thereof.

It is also within the scope of the invention, to provide simple and inexpensive means for increasing the life and efficiency of the gripper or holder, which will be thoroughly practical in use.

lVith the foregoing and other objects in view, the present invention resides in the peculiar formation of the gripper or holder disk for the twine, as hereinafter set forth in detail.

The invention is illustrated in the accompanying drawing, wherein Figure l is an elevation of one side of the gripper or holder. Fig. 2 is an elevation of the other side thereof. Fig. 3 is an enlarged sectional detail taken on the line 3-'3 of Fig. l.

The twine gripper or holder embodies the companion or complementary disks 1 and 2, which are secured together in the usual manner, and each of whichis provided with Copies of this patent may be obtained for five cents each, by addressing the a series of peripheral notches 3, coinciding or registering with the notches of the opposite disk for cooperation with the usual twine hook (not shown).

In carrying out the present invention, the outer side of each of the disks 1 and 2 is beveled around each notch 3, as at l, and the beveled edge a of each notch is provided with a series of oblique grooves 5 forming the serrated edges 6 for the notches 3. The bevels 4 extend from the outer sides of the disks to the inner sides thereof, and the grooves 5 extend to the edges of the bevels.

Vith the provision of the peculiar bevels and grooves it has been found in practice, that notwithstanding the fact that the notches having the serrated edges become worn due to the continued friction to which they are subjected, they will always effectively receive and hold the twine. In this manner, the life and efficiency of the gripper is materially enhanced, it being a frequent occurrence with the ordinary gripper 0r holder, for the same to become worn out and inelficient within a short period due to the rounding and smoothing of the twine notches.

Having thus described the invention, what is claimed as new is A twine gripper for binders embodying a pair of parallel spaced disks secured together, the peripheries of the disks having coinciding curved notches, the outer sides 'of the disks being beveled around each notch, the bevels extending to both ends of the notches and extending from the outer sides to the inner sides of the disks, each bevel being provided from end to end with a series of grooves extending to the edges of the bevel, and said grooves being arranged obliquely.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.

RICHARD H. MOORE.
