SPECIFICATION forming part of Letters Patent No. 623,925, dated April 25, 1899.

Application filed January 3,1899.

Serial No. 700,904. (No model.)

T0 at whom, it may concern;

Be it known that I, THOMAS MOVEIGH, of Danielson, county of Windham, State of Connecticut, have invented an Improvement in Knot-Tying Devices for Spoofing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In United States Patent No. 498,185,

to me May 23, 1893, a knot-tying shown and described particularly adapted for use in connection with spoofing-machines, hereby the ends of threads to be united s evered e'lesetoth'eknotI One o thekiiot tiers was re *ed-fe-r each spool in said patent, attached by suitable set-screws to a longitudinally-extended rod back of and above the spools, and while the said devices are entirely and satisfactorily operative in practice the use of such a number on a spooler-frame is too expensive.

My present invention has for its object the production of means whereby a single knottier can be used for tying knots on the ends of yarns from several spools--as, for instance, all of the spools on one side of the frame.

Figure l in front elevation represents a sufficient portion of a spooler-frame to be understood, with my present invention applied thereto; and Fig. 2 is an enlarged transverse sectional view on the line a: m, Fig. 1, of the knot-tier, the traveler to which it is attached, and the guide-support for the traveler.

The spooler-frame A, spools B, bobbin-holders O, and guides D are and may be all as common in spoolingmachines, and I have herein illustrated my invention in connection with such an apparatus.

A non-cylindrical bar a is shown in Fig. 1 as mounted on suitable standards a above and back of the spools, said bar being shown in Fig. 2 as oblong in cross-section and set on edge to form a combined guide and support for a traveler adapted to slide thereupon. The traveler comprises a body t, having a hole therethrough corresponding in shape to the cross-section of and to receive the guide-supgranted device is cross-section might be adopted for the guideport a, the non-cylindrical shape of the latter preventing tipping movement of the traveler without interfering with its lateral sliding movement. Any suitable or convenient support so long as the non-tipping and free sliding movement of the traveler is attained. The top of the traveler is shouldered at t and provided with an upturned stud t the latter entering the offset boss 0 of the knot-tier, which usually rests on the shoulder t and is held in adjusted lateral position relatively to the traveler by a set-screw 20, Fig. 1.

The knot-tying device itself, comprising the body 0, slotted to receive the shanks of the knot-forming nibs d, the thread-cutter e, pivoted at e at the rear side of the nibs, so as to cut off very close to them the yarns pinched between the nibs, and the combined thread-support and cutter-actuator f is and may be substantially as shown and operating in my patent referred to.

Obviously the operator can push the traveler along the guide-support into position adjacent any spool on the side, according to the yarn to be knotted, thus enabling a single knot-tying device to serve for the entire side of a spooler-frame. If the frame be a very long one, two of the knot-tiers could be mounted on the guide-support instead of one, as herein shown. Each side of the spooler will be similarly equipped.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an apparatus of the a longitudinally-extendedguide-support, and a knot-tying device free to slide on said support, and means to prevent rotation of said device on its support during sliding movement.

2. In an apparatus of the class described, a longitudinally-extended supporting-bar,-a traveler non-rotatably mounted thereupon and free to slide along said bar, and a knottying device carried by the traveler.

3. In a spoofing-machine, a longitudinallyextended guide-support located above and back of the spools, a traveler free to slide class described,

just the said device on the traveler,

ter being movable longitudinally of the bar to bring the knot-tying device into position adjacent any desired spool.

In testimony whereof I have signed my name to this specification in the presence of 15 two subscribing Witnesses.

THOMAS MCVEIGH.
