erson, Passaic county, New. Jersey, ave in vented certain new and useful Improvements in Quilling Machines ,and we do hereby declare the following to be a full, clear, and exact description 0 same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part'of this specification. V Thisinvention relates to that general class of quilling or cop Winding machinesin which the windin of the cop is effected by rotating the same re l the attenuating or building-up of the cop is effected by advancing thethread-guide relatively to the cop. 1 r

Our present lnvention is directed particularly to, first, the means for Oscillating and gradually advancing thethread-guide relatively to the cop being wound; second, the clutch connections between the spindles and theirdriving means,thisfeature being an improvement on aclutch mechanism dis-v closed in the patent to Adsit, fi 757,081; and, third, the meansfor supplying'thethread to the quills.

In the drawings, the standarda; rails 5; intermediate rails c; brackets d;n1ain driveshaft 0; fast and loose pulleys f; and ulley g are or may be all. substantiallyasan for the purposes set forth in'the above referred to. V r p h designates horizontal bolsters supported patent to Adsit Specification of Letters Patent. Application filed February 15, 1906. Serial No. 301,138.

the invention, such as willenable others skilled in the art to a which it appertains to make and use the atively to the thread-guide while Patented Oct. 6, 1908.

by stems twin the rails c. In each bolster is journaled a spindle-driving shaft 3' carrying a whirl 7c at one end, engaging a belt Zwhich extends over the pullley g and its counterpart (not shown) at the other end of the machine, and at the other end a clutch member m'whichis a collar on the shaft is formed with a tapered longitudinally extending lug or tongue n. r

0 designates the spindles, the same being j ournaled in thelrails b and at their rear ends in theshaftsj. On eachspindle is an annularly grooved collar 1) formed with a tapered tongue or lug qprojecting toward the tongue. or lug nof collar m, said collar p being the counterpart clutch member of clutch-member m;

this arrangement is to cause the shaft j,

which is continually rotating, to start its spindle 0 gradually when the latter is thrown into movement, so saving a sudden strain on the thread being wound when the s indle is j pushed back, the clips firstiact on t e collar m as a sort of friction clutch, the spindle taking on the rotary movement of the shaft y' with more or less increasing speed until finally the tongues g and n abut and both the spindle and shaft rotate together at the same speed. The free ends of the clips 1" are turned outwardly or flared; thus, the rotary action which the spindle assumes merely as the resultof frictional contact between said clips and-part m is itself a gradually increas ing one. i i

s is a push-rod controlling each spindle, the same carrying a fork t which engages in the annular groove of thecollar p of the spindle and being normally pressed outwardly by a spiral s ring a coiled between a collar 1; on

the pus -rod and a rail w of the frame of the machine.

w is a notched stopv on the rail 6 which, being engaged by a finger y projecting from the push-rod, holds the push-rod back in the position where the spindle is clutched with shaft 3'. z-designates the thread-guides, one

for each spindle, and l the thread-guide-advancing-rod, both being arranged to move freely in a longitudinal direction in the rail b, which they penetrate; the thread-guide also penetrates and is supported in the rail w. The thread-guide-advancing-rod carries the usual cop engaging friction wheel 2, and

' it is connected with the thread-guide by the usual fork 3 carried by the latter and engaging between nuts 4 on the threaded portion 5 of said rod.

Each thread-guide rests on a small grooved worm wheel 6, the several worm wheels for each row of winding units being fixed on a rock shaft 7 journaled in the standards a. In order to permit adjustment laterally and at the same time secure the worm-wheels against free movement longitudinally of shaft 7, we prefer to secure each worm wheel by a U-shaped spring 6 which is slipped into the annular groove 6 of a boss 6 on the worm-wheel, the boss being cut through to its bore in its groove at one side so that the spring may bear against a flat 6 d on the shaft 7. As usual, when the thread-guide has been caused to feed outwardly to the extent necessary to complete a cop by the friction wheel 2 in the reciprocations of the parts 1 and 2 intermittently engaging the rotating cop, the operator presses down on the friction wheel 2, causing the rod 1 to tilt in the rail 6 as a fulcrum whereby to disengage its thread from the worm wheel 6, whereupon rod 1 and the thread-guide connected therewith may be pushed backward and reset. In order to prevent the threaded rod from being unshipped from the worm wheel 6 at this time, a forked guide 8 carried by rail w and straddling the rod 1, is provided.

The worm wheel 6 above referred to takes the place of the fork heretofore usually used, and, in addition to several other advantages, it avoids the up and down rocking effect to which the threaded-rod 1, and consequently, more or less, the thread-guide-rod, were subjected.

The rock-shafts 7 are oscillated in the following manner: 9 is a lever fulcrumed in one of the standards a. Each arm of this lever is connected with the shaft 7 by a link 10 and a band 11 extending over and secured to the periphery of a band wheel 12 on shaft 7. Tension on the parts 10 and 11 is normally maintained by a spiral spring 13 which connects the standard a with a band 14 passing over a band-wheel 15 in the direction reverse to the band 11. Thus as the lever 9 rocks,

it causes the shafts 7 to also rock in suchmanner as to alternately move the rows of thread-guide-advancing-rods 1 outwardly. The rocking of the shaft 9 is effected from the shaft 0 by a worm 16 on shaft 6, a worm wheel 17 on a shaft 18 journaled in a bracket 19, a cam 20 on shaft 18, a lever 21 fulcrumed in the standard a and a link 22 connecting levers 21 and 9.

23 is the usual su erstructure for supporting the supply bobbins and their accessory mechanisms. In the present instance, the bobbins 24 are supported in an inverted position, each directly above the spindle which it supplies, by being arranged on a fixed spindle or skewer 25 depending from one of the rails 26 of the superstructure 23. Any suitable means for keeping the bobbin against downward displacement, such as the bobbin cap 27 containing a bent plate spring 28 which engages in an annular groove 29 in the spin dle 25 may be provided.

30 and 31 are thread-guides to prevent too much ballooning of the threads between the bobbins and the spindles.

In devising this arrangement we have had in mind two well known arrangements of su pply bobbins for machines of this character, to wit, the one where the bobbin rotates on a horizontal axis, and the other where the bobbin stands vertically and discharges upwardly. Our present arrangement dill'erentiates from both of these and results in at least three advantages, to wit, first, leading the thread directly, without guide-rods etc. changing its course, and in the most practical, convenient and accessible manner, from the supply, to the quill; second, the ability to start the machine instantanemlsly at full speed without breaking the thread, which of course can not be done in the case of a horizontal supply bobbin, where inertia and bearing-friction must be reckoned on; and third, a uniform and regular pull-ofl' or feed, without regard to what part of the bobbin is discharging at that time, which latter feature seems to be due to the combined. effects of gravity and the tendency of the thread to balloon between the quill and bobbin, the thread-coils as their original spooling tension is caused to release literally falling away from the bobbin, even at the angle between its body and lower flange, so that there is no catching of or sudden resistance on the thread at any time. So far as em loying the bobbin cap to prevent the end coi s from catching in the angle represented by the body and lower flange of the bobbin is concerned, We may thus even dispense with such bobbin cap, though it is of course nec essary if the bobbin heads are not without roughness.

The operation is substantially the same as in the case of the Adsit machine herein before referred to, the spindles (clutched with their drive shafts) rotating and thus drawing off the thread from the supply and winding it on the cops while the thread guides are reciprocated through the threaded rods 1 from the oscillating worm-wheels 6 and simultaneously advanced to effect the lengthening of the cop by the friction wheels 2 intermittently turning the threaded rods 011 the worm wheels as, in their reciprocations, they bring up against the wound cops. When any cop is fully wound, the cone 32 on the forward and break the spindle clutch, stop ping the rotation of the corresponding spin- Practical application of our improvements has demonstrated that thereby machines of this kind may be not only run at a speed much higher than machines at present in use,

but that the machine may be preci itously set V to full speed, all without brea 'ng or burning the threads and causing them at at any time to feedoff more copiously than the quills can take them up.

Having thus fully described our invention, what we claim as new and desireto secure by Letters Patent is:

1. In a quilling machine, the combination, with the frame, of a rotary spindle, a longitudinally reciprocating thread-guide, a threaded rod connected with said threadguide to move therewith longitudinally, and

' an oscillatory part having a peripherally serrated portion engaged peripherally by said threaded rod, substantially as described.

2. In a quilling machine, the combination,

with the frame, of a rotary spindle, a longitudinally reciprocating thread-guide, a

threaded rod connected with said threadguide to move therewith longitudinally, a

rock-shaft, and a worm Wheel on said rockshaft engaged eripherally by said threaded rod, substantia ly as described.

3. In a quilling machine, the combination, with the frame, of a rotary spindle, a longitudinally reciprocating thread-guide, a threaded rod connected with said threadguide to move therewith longitudinally, a rock-shaft, a worm wheel on said rock-shaft en aged eripherally by said threaded rod, an a for ed guide carried by the frame and straddling said threaded rod, substantially as described.

In testimony, that We claim the fore oing, We havehereunto set our hands this 6t day of February, 1906.
