Specification of Letters Patent.

Patented Sept. 2, .1 S) 1 2%.

To all whom (it new concern,

lie it known that I, Maniacs Pnrrano, a citizen of the United States,a 1d a resident of Newark, :lflssex county, New Jersey, have invented certain new and useful improvements in inding:Machines, (Qase L3,), of which the following is a speclt sation.

My invention relates to wind ng machines for winding cops, of that k nd n which relative reciprocation is produced hetween a thread guide and a winding spindle, and the successive advances of the thread are p,r ,dnced byitriction roller means to. which rotary motion is imparted at inter- 'vals by the winding spindle.

The invention relates particularly to that type of such machines which wind cops on paper tubes, the cops having tapered ends and a cylindrical body. The rear end (it such :1 C0}? iS known as the heel. The throw of the thread due to the reciprocation off the thread guide is known as the traverse, and a complete traverse may be regarded as being composed Of an out stroke and a back stroke,

The object of the invention is to provide a friction roller which is normally at a distance from the windin spindle, and which, l. ,etween traverses, during the building of the heel, moved toward the winding spindle so. as to be rotated thereby, thus producing the advances, for forming the reel of the cop.

A further object is to move the friction r-oller diminishing distances toward the spindle on the successive back strokes during the building of the heel.

Another object is to provide means for causing the ft'riction roller to approach the winding s indle on the early ba t okes, which means is mounted on a statimiary part, such as the frame oi" the machine, or independently of the rec procating parts, and is adapted to be contacted by a suitable contact n e nl'icr reciprocating with said parts. 'i A -iarticnlarobject of the invention is to provide active heel shaping mechanism, which is mounted independently of the reciprocating parts and actuated by the back strokes thereof to move the friction roller toward the spindle so as to be rotated thereby.

A. further objectis to simplify and improve the construction and arrangement of the several parts.

\Vith these and other objects in view, the invention consists in the constructions, arrangements and combinations hereinafter described, illustrated by the preferred emlmdiments in the accompanying drawings, and more particularly pointed out in the appended claims.

In the said drawings: Figure 1 is an end elevation of the machine; Fig. 2 is a sectional front elevation showing the mechanism for swinging the traverse bar; Fig, 3 is a plan view of the parts in front of the :lrame oi, the machine, showing the heel of the cop partially coinplctcd and the traverse bar, Friction roller and thread guide at the end of the out stroke; Fig. 4- is a similar view, but showing the reciprocating parts at the end of their back stroke, with the traverse bar and friction roller swung toward the spindle and the roller contacting with the thread of the cop; Fig. 5 is a similar view, showing the heel completed and the flriction roller working on the partially completed body of the cop. The parts are shown at the end oi the back stroke. l n dotted lines are indicated the completed cop and the friction roller at the end of its final back stroke. Fig. (i is a sectional detail, showing the spring actuated incomplete nut for coupling the friction roller to the threaded traverse bar; l ig. T is a detail sectional view showing the fork or yoke for coupling the friction roller with the thread guide; and

.ll lg. 8 a detail plan view of the universal joint connection between the rear end oi the traverse bar and the oscillating arm for reciprocating the same,

In these drawings, the nluncral ll indicates any suitable :lorm, o'l frame, which in practice is considerably larger than is indicated in the drawings. On the frame is mounted a driving shaft 12. This shaft 12 rotates a plurality of spindles 13, projecting forward through the frame; but only one spindle is illustrated in the drawings. The shaft 12 may drive the spindle 13 by means of a bevel friction disk 15 and a bevel friction gear ill; but it is obvious that such details are immaterial.

The numeral 17 indicates a suitable form oi, thread g 'lide, between which and the spindle 13, a relative recipmcation is probuilding cop.

duced. It is regarded as preferable to reciprocate the thread guide; and the means for effecting such reciprocation may be varied widely. In the illustrated construction, a cam-shaft 18 (driven in any suitable manner by the driving shaft 12 or otherwise) is provided with a cam 19, which oscillates a spring-supported lever 20, which in turn oscillates a rock-shaft 21, being con-- nected with an arm 22 thereof by a link 23. An arm 24 carried by the rock shaft is com nected to a traverse bar 25 and reciprocates the same. In accordance with the best form of the invention, the reciprocation of the traverse bar is imparted to the thread guide in the following manner: A friction roller 26 is mounted on the traverse bar; and this roller is shown as being provided with a collar extension 27 which is engaged by a coupling or fork 28, which fork is secured adjustably to a reciprocating rod 29 on which the thread guide 17 is adjust-ably mounted.

According to the best form of the invention, the thread guide is mounted independently of the traverse bar 25. To this; end it is shown mounted on the rod 29, which itself is mounted for longitudinal rectilin-.

ear reciprocation, as by being received in stationary bearings 30 on the frame. Thus,

by virtue of the coupling 28, the thread guide partakes of the reciprocation of the traverse bar 25, but said bar moves laterally independently of the thread guide, in the manner hereinafter described.

The roller 26 gives the successive advances to the thread guide 17 for the the is heel of the produced by building of This advance cop. screwthreaded means through the rotation of,

the friction roller at intervals by the winding spindle, through contact of the pe-,

riphery of the roller with the thread of the ment of the invention illustrated, the traverse bar 25 is threaded, and the friction roller 26 is adapted to be coupled with they threads thereof; so that rotation of the roller on the traverse bar advances the roller along the bar. Through suitable connections, such as already described, the roller imparts this advance to the thread guide 17.

The roller 26 is provided with a form of quick release device, which is adapted to travel with the roller and has movement relative thereto for engagement and disengage- In the particular embodi- Suitable means are provided for shaping the heel of the cop, which means may be widely varied. In accordance with this fea ture of the invention, the traverse bar 25 and the friction roller 26 are laterally yieldable for the purpose of enabling the friction roller to be brought into frictional contact with the thread of the cop at the conclusion of each back stroke during the building of the heel of the cop. In the best form of the invention, the traverse bar is swiveled at its rear end for this purpose; being connected by universal joint connection with the arm 24. Such joint may be of various forms. As shown, the upper end of the arm 24 is provided with spaced ears 36, concave on their inner faces and having transverse slots 37, in which are received a pivot pin 38 secured to the ball end of the traverse bar 25. The bar is, thus, enabled to swing sidewisetoward and from the spindle 13.

The fork 28 is swiveled, as indicated at 39, so as to cause no binding when the traverse bar 25 and the friction roller 26 are swung toward the spindle.

In accordance with the form of the invention illustrated, mechanism is mounted inde pendently of the reciprocating parts and is actuated thereby to move the traverse bar and roller laterally between traverses. In the best construction, a bell-crank lever has a long pivot portion 40 mounted in a suitable stationary support or bracket 41; and one arm 42 of this lever is disposed in the path of an abutment or contact member 43 mounted adjustably on the shaft 29 of the thread guide. The other arm 44 of said lever is connected by a link 45 with a projection 46 on a swinging bracket 47. Said bracket 47 is pivotally supported as indicated at 48, and affords a bearing through which the traverse bar 25 slides. As will be apparent, when, the abutment 43 pushes the arm 42, which is preferably inclined forward, to the rear, the traverse bar 25'and the roller 26 are moved toward the spindle 13. 7V hen the contact member 43 again moves forward, the traverse bar and the roller, and likewise the lever 42, are restored to their former positions by a spring 49, which draws the bracket 47 against an adjustable stop 50. Instead of the abutment 43, moving contact means may be provided'in any suitable manner, as, for example, the fork 28 may be caused to contact with the arm 42 of the hellcrank' lever.

In the operation of the invention, at the conclusions of the back strokes of the thread Lose distributing means during the building of the heel of the cop, the lever 42 is actuated and causes the friction roller 26 to approach the spindle 13 and thus be rotated by frictional engagement with the thread of the building cop. This rotation advances the roller and he thread guide, and also the abutment 4L8. Consequently, on each successive back stroke, during the building of the heel of the cop, the abutment 43 moves the lever a shorter distance, and the roller, consequently, approaches a less distance toward the spindle as the cop builds up in thickness. Finally, the abutment no longer contacts with the lever; and thereafter the roller is not advanced toward the spindle, but has rectilinear movement only. The roller 26 now proceeds to build up the cylindrical body of the cop; for this purpose, contacting on each back stroke with the high part of the cop and producing the requisite advance. In the preferred form of the invention illustrated, the roller 26 is in the nature of a thin disk, whose width is materially less than the traverse of the thread (indicated by the letter Z) in the drawing), and the thread guide 17 is located substantially opposite the center or high point of the periphery oil. the disk, said periphery being slightly inclined and rounded. By adjusting the stop 50, the width of the cop may be varied,

\Vhile the machine is shown as operating on a tapering spindle and cop tube, it operates as well on cylindrical spindles and tubes.
