This invention relates to. swifts or skein holders. i

.rIn. the handling of skeins, and particularly in preparing skeins for dyeing, ..aiti;has heretofore been customary to mount theiskein on a rotatable reel with a block on an auxiliary roller inserted at the lower part of thefskein. The yarn is then drawn from the skein. as desired. The reels employed are noisy, are burdensome for the operator, frequently permit; of catching or snagging of the. yarn, require. lubrication of a character such that oil may spot-the yarn carried thereon, and have other disadyantages.

It is the principal object of sthe'i'present invention to provide a swift or skeiri; holder which eliminates the objectionable features of the devices for the same purpose heretofore available.

It is a further object of the-present invention to provide a swift or skein holder inwhich the component parts are light in weight, easy of adjustment, and which may be readily accommodated to the lengths of skeins now in use.

It'is a further object of the-present invention to provide a swift or skein holder in which the drag on the yarn is reduced, thereby permitting starting at greater speeds with'reduced breakage, and with reduced power costs and maintenance.

It is a further object of the fpresent invention to provide a swift or skein holder in which the moving parts may be readily stopped by the operator even when travelling at very highest speed without any danger or likelihood of injury to the operator.

It is a further object of thefpresent invention to provide a swift or skein holder with which the skein is opened for withdrawalof the yarn in any improved manner.

Other objects and advantageous features of the invention will be apparent from th'e specification and claims.

The nature and characteristic{features of the invention will be more readilynnderstood from the following description, takenin connection with the accompanying drawingsi forming part hereof, in which:

Figure l is a view, in side elevation, of a swift or skein holder in accordance-"with the present invention;

Fig. 2 is a front view thereof; I

Fig. 3 is a horizontal sectional view, enlarged, taken approximately on the line- 3 3 of Fig. 1;

Fig. 4 is a horizontal sectionalview, enlarged, taken approximately on the line 4-4 of Fig. 1; and

11 Claims. (Cl. 242-127) Fig. 5 is a fragmentary vertical sectional view, enlarged, takenapproximately on the line 55 of Fig. 1.

. Like numerals refer to like parts throughout the several views.

It should, of course, be understood thatthe description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

Referring now more particularly to the drawings, the swift or skein holder, in accordancewith the present invention, preferably includes a supporting frame l0, having a base H adapted to be secured to the floor or any other desired support. The base H has a vertical upright I2 secured thereto. The upright l2 may be of. any desired shape, but is preferably C-shaped in horizontal cross section and includes a Web portion I3 having an upper vertically extendingislot l4 and a lower vertically extending slot l5 therein. t

Upper and lower heads I6 and H are provided, carried by the upright I2, as hereinafter explained.

The upper head I6 preferably includes a pair of spaced vertical side plates I8 and I9,-connected by a central bar 20 to which the side plates l8 and I9 are secured. The side plate I8 has a spacer block 21 secured thereto in alinement with the bar 20 for engagement with the outer face of the web I3. An adjusting stud 22 is provided, having an externally threaded end portion. 23 for engagement in complemental threads in the block 2I and having a shoulder 24 for engagement with the inner face of the Web l3. The stud 22 has a handle portion 25 for manually clamping the upper head l6 at the elevation'desired by the operator.

On opposite sides of the central bar 20, and extending between the side plates I8 and I9, 9. pair of freely rotatable rollers 26 are provided with their longitudinal axes spaced and parallel and preferably in the same horizontal plane, and supported as hereinafter explained.

The lower head I'I preferably includes a pair of spaced vertical side plates H8 and H9, connected by a central bar I20 to which the side longitudinal axes spaced and parallel and preferably in the same horizontal plane, and supported as hereinafter explained.

The lower head I! preferably includes a slide block 38 secured to the side plate I I8 and movable in the slot l5, guide brackets 3| and 32 being provided for engagement with a. vertical guide rod 33 secured to the upright 12 by brackets 34 at its upper and lower ends. The lower head I! is freely movable vertically and a spring 35 is provided on the lower part of the guide rod 33 and supported by the lower bracket 34 for engagement by the lower bracket 32 for absorbing any shocks, if the lower head I! is permitted to move downwardly without any restraint.

The mounting of rollers 26 is shown in detail in Fig. 5, the side plate H9 being selected as illustrative of the other side plates.

Extending between each of the side ,plates 18 and I9 and H8 and H9, for each roller 26, a rod 36 is provided, having'a portion 3'! of reduced diameter at each end, with which the inner race 38 of ball bearing 39 is in engagement, and terminal end portions 46 of reduced diameter for tight engagement in the side plates. 'The outer races 4| of ball bearings 39 each has a collar 52 secured thereto. The collars 42 each have an inwardly extending flange 43 and an outwardly extending flange M which is disposed within recesses 45 in the side plates.

The collars 42 have extending therebetw een and in engagement therewith lengths of tubing 26a movable therewith to provide the roller 2t The outer surface of the roller 26 is preferably polished to eliminate adherence of the yarn thereto. The side plates l8 and ['9 of the upper head it and the side plates H8 and H9 of the lower head prevent sidewise displacement of the skein.

The upper head It and the lower head I"! are preferably made as light in weight as possible, consistent with adequate strength, and for this purpose the parts thereof, with the exception of the bearings 39 and the races 38 and 4|, are preferably made of aluminum. This not'only facilitates adjustment and handling-of the heads [6 and I! by the operator but also reduces the inertia or flywheel effect of the rollers 26 so that they may be readily rotated upon starting up and may be readily stopped by the frictional engagement of the hand of the operator.

The mode of use will, it is thought, be clear from the foregoing, but it may be noted that the upper head 16 may be adjusted at the desired elevation in accordance with the desire of the operator. A skein is then hung over the rollers 26 of the upper head It. The lower 'head I! is then moved upwardly and the skein positioned so that the roller 26 thereof are in engagement therewith, the lower head I! being supported by the skein and the skein being in opened condition. The yarn may readily be withdrawn from the skein which rotates on the rollers 26 of the upper and lower heads Hi and IT. The skeinis thus maintained in an open condition during the withdrawal of the yarn. When all the yarn of the skein has been removed, the lower head'l'l will tend to fall by its own weight, the shock thereof being taken up by the spring 35. Another skein may then be mounted as before.
