OPERATING MECHANISM FOR CORD-HOLDERS OF GRAIN-BINDERS.

SPECIFICATION forming partof Letters Patent No. 366,372, dated July 12 1887.

Application filed May 19. 1883.

To all whom it may concern.-

Be itknown that I, JosEPH P. BULLooK, of Milwaukee, in the county of Milwaukee, and in the State of \Visconsin, have invented certain new and useful Improvements in Operating Mechanism for Cord-Holders of Grain- Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to devices for operating the cord-holders of grain-binders; and it consists in certain peculiarities of construction, as will be more fully set forth hereinafter.

The drawing is a perspective view ofmy invention.

A is the main shaft of the knot-tyer, and A is a sleeve thereon, which belongs to the mainframe of the machine,of which my present invention forms a part. B is another sleeve on same shaft, but separated from sleeve Aby the wheel 0, and located between that wheel and the wheel D at the end of the said shaft A. From the sleeve B there depends the frame 2 5 B, solid therewith or connected thereto, and of a general L-shape in cr'osssection, which frame is cut away, as shown at b in the drawing, to permit the needle to pass therethrough. The front of this frame is provided with a bearing, b, to receive the shaft e of the notched disk E, and secured to or cast with this disk is the bevelgear-wheel E, the teeth of which mesh with those on a pinion, F, which is on the inner end of a shaft, f, pass- 5 5 ing through a bearing formed at b in the side of the frame B, and which shaft bears at its outer end the wheel F. This wheel is provided with cogs at, say, three equally distant points, f on its periphery, separated by 0 three blank portions, and its outer plate is concaved between the cogs, and the wheel 0 immediately above it has corresponding cogs, c, at one point only, and otherwise presents a blank surface on its periphery, and has a 5 side flange, c, all around it except at the cogs; hence, as the wheel 0 is revolved by the shaft A, when the cogs c on the wheel 0 encounter one set of the cogs f on the wheel F, the latter wheel will be revolved just so Serial No. 95,549. (No model.)

long as the two wheels are in mesh, or suf- 5o ficient to turn the diskEone notch, and then, as the blank surfaces of the wheels 0 and F do not touch each other,and as the side flange, c,0n the former wheel just moves within the concave on the outer side of the latter wheel without contact, the wheel F is not again revolved until the wheel 0 makes another complete revolution and its cogs c encounter the next set of cogs, f on the wheel F, the meshing of which serves to turn the disk E another notch, and so on.

G is the shoe of the cord-holder, which is pivoted at g to the frame B, and as the needle (not shown) carries the cord down into one of the notches in the dis a E the shoe is forced 6 in toward the disk by spring H, so as to clamp the cord upon the disk and securely hold it.

The device herein illustrated shows a disk E supposed to have six notches, and with its bevel gear-wheel E furnished with double the number of cogs that the pinion F bears, and hence the wheel F would have three sets of cogs,f,- but it will be understood that I do not limit myself to any particular number of notches or number of cogs, so long as the device is constructed with proper relative proportions (as regards the number of notches and the size and number of cogs, &c.) of the several parts.

Heretofore the notched disks analogous to my disk E have been operated by a pawl-andratchet device, which was cumbersome and necessitated a number of extra parts and attachments; but my present device does the 85 work equally well and is much simpler.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the cord holding o disk having a bevel-pinion secured to it or forming part thereof,ashaft carryinga bevelpinion on one end for meshing with that on the holding-disk, and provided at the other end with a wheel having cogs at intervals on 5 its periphery and intermediate smooth concave surfaces,with a wheel on the main tyershaft independcntof the tyer-operating wheel,

- having a cog-segment at one point on its rim,

2 seesvz In testimeny that I claim the foregoing I I0 have hereunto set, my hand, on this 15th day of May, -1S83,-in the presence of two witnesses.

which is otherwise perfectly plain, substantially as set forth.

2. In a grain-binder, the combination with the knoiting mechanism and its wheel D, of cord-holder E E G, spring H, shaftf, having pinion at one end and intermittent gear-wheel at the other, with the wheelO, having a 30gsegment on its periphery, as set forth.
