KNOT-TYING DEVICE.

SPECIFICATION forming part of Letters Application filed October 24:, 1892.

To all whom it may concern.-

Be it known that I, THOMAS MCVEIGH, of Grosvenor Dale, county of Windham, State of Connecticut, have invented an Improvement in Knot-Tying Devices, of which the followin g description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a simple, easily operated, and officient knot tyer, it being especially applicable for use with spooling machines.

Figure 1, shows a portion of a spooling machine with my improved knot tyer in place. Fig. 2, on a larger scale shows one of my knot tyers in plan View, the rod supporting it being broken off; Fig. 3, a side elevation thereof; Fig. 4, a section in the line wa:, Fig. 2; Fig. 5, a section in the line w'oc, Fig. 2; and Figs. 6 and 7, details of the different positions of the thread during the operation of tying a knot.

The frame A; spools B; bobbin holders C; and guides D; are and may be all as common in spooling machines, I having chosen herein to illustrate my invention as applied to a machine of that kind. The rod a, has adjustably connected to it by a suitable set screw 1) the body or frame 0 of the knot tyer. This frame is slotted for the reception of the shanks d of the knot-forming nibs d having erator may draw one part of the thread, the nibs holding the thread between them sufficiently hard to enable the looped part of the knot to be drawn up off the nibs, leaving the thread held by the nibs in the coil and makingahard knot. The shanks are provided with shoulders ol sufficiently abrupt to form steps to determine the position of the thread to be tied and then coiled about the nibs as in Fig. 6.

At the rear side of the parts cl, d, I have pivoted at e a thread-cutter 6', its upper end working close to the rear sides of the nibs, so as to cut off very close to them the thread pinched and held between the contiguous Patent No. 498,185, dated May 23, 1893.

Serial No. 449,832. (No model.)

to be tied together, Will, with one hand or finger hold said threads on the thread support f and will press down onthe support sufficiently to move the cutter away from the rear side of the opening between the nibs; and this done, the operator with his other hand will wrap the two threads about the nibs and cutter, and bring the threads so wrapped about the nibs, across the part of said threads lying on the support f and then the undermost portions of the said threads, the support being yet depressed, are lifted from the support and drawn snuglyinto the space between the nibs, when the operator will release the support, let the cutter cut off the free ends of the threads beyond the nibs, after which the operator, by lifting or pullin'g'upwardl y on the threads will cause the parts thereof previously wrapped about the nibs to be drawn up oflf the free ends of the nibs, and in so doing the nibs will hold between them the ends of the threads next to where the threads were cut 0E, as stated, and a hard knot will be tied, the knot being so close to the free ends of the thread as to scarcely show any free ends. For the greatest convenience, I have offset the frame c as at 0 so as to bring the support f and the nibs and cutter into the most convenient position for the operator standing in frontof the machine, the operator while tying the knot holding the spool by pressure thereon of his left hand.

I am aware that many different forms of knot tyers have been devised, but none, so far as I am aware, have ever been put into practical use on spooling machines.

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

1. In a knot tyer, the stationary nibs having a thread receiving space between them,

and a cutter arranged close to said nibs and adapted to cross the said space, combined with a cutter actuator havinga finger rest, 5 substantially as described.

2. In a knot-tyer, the frame, the shanks supported therein and provided with shouiders having nibs, and a cutter arranged close to said nibs, combined withamovable cutteractuator and spring to operate the actuator to in one direction, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS MGVEIGI-I.
