To (LZZ whom it may concern.-

Beit known that I, PERLEY LAELIN, a ctizen ofthe United States, residing at Varren, in the count-y of Worcester and State of Massachusetts, halve invented certain new and useful Improvements in BobbinHolders for SpoolingMacliines,of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertaius to make and use the same.

My present invention relates to the conslruc tion of bobbin-holders for spooling-machines and to the manner of supporting the same in combination with thc rail or frame of the inachine, the prime objects of the invention being, rst, to provide a bobbin-holder that is convenient for.the introduction and discharge of the bobbins and for the observation of the same while'runniug; second, to provide convenient facilities for the regulation of the friction or tension on the bobbin by means of a laterallyadj ustable weight, wherebytheholder is adapted for heavy or light work; third, to afford facilities for the adjustment of the holder longitudinallyinrelation toits support; fourth, to provide means for the lateral adjustment of the guard to accommodate bobbins of different diameters; fifth, to provide a rolling or rocking bed or support for the bobbin and means for retaining the bobbin laterally, as more fullyhereinafter set forth,and, siXth,to provide means for supporting the bobbin-holder in combination with the spindle step-rail of the spooling-machine, as hereinafter described. These objects I attain by mechanism the na` ture, construction, and operation of which is explained in the following description, the particular subject-matter claimed being here inafter definitely specified.

In the drawings, Figure l is a side View of a bobbin-holder constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a section of the same at line x x, Fig. l. Fig. 4 is a sectional view show- Fig. 5 is a view showing the relative arrangement of the bobbin-holder, the spindle-supporting rails, the spindle, spool, and thread-guiding devices in the spooling-machiue.

In the drawings, A denotes the frame or base of the bobbin-holder,which is made dovetailed, or with beveled or flanged sides along its opposite parallel edges, and is provided at its rear end with an upward-projecting arm, A', and with an ear, A2, at its frontend.

B indicates a forked guard or cradle, having an interior space for receivingr the bobbin of somewhat greater width than the diameter of the bobbin or cop. One side of the guard is fitted with an upright inner surface, b, against which the bobbin rests when in operation. Said guard B is attached at its rear end to the upright arm A of the frame by means of a screw or bolt, O, which passes through a laterally-extending slot, c, formed in the end of the guard in a manner to afford lateral adjust-- ment of the guard upon the frame A. The lower edge of the guard is rounded at b`L for the passage of the thread beneath the same.

D indicates the bobbin supporting bed, which is pivoted in lthe frame atd d', 1ongi tudinally parallel with and in .position to support the bobbin at the proper height in relation to the side of the guard. Said bed is vformed asa roll or rocking piece, upon the top of which the bobbin is supported with its side parallel with and against the inner surface, b, of the guard. The position of the bobbin is shown oy dotted lines in Figs. 1, 3, and 4.

F indicates an upwardly-projecting arm or presser-bar, preferably formed of wire and connected with the bed D, or supported on the pivoted journals thereof, to swing or rock back and forth at its top end, and serving to press against the bobbin and retain it against the surface b of the guard, thereby confining it steadily-in position while imparting the required degree of tension when the thread is being unwound.

I indicates a ball or weight mounted on a screw-threaded stud, t', which is fitted in the supporting-bed in such manner that it can be turned in or out to increase or diminish the leverage, or to carry the weight nearer to or farther from the axis of the bed and presser for increasing or diminishing the force with which the presser F is caused to bear against the bobbin, and the consequent variation of the pressure of the bobbin against the surface b, thus increasing or diminishing the tension ICO A or draft upon the thread as it is drawn from provided with a lip, Z, that locks over the upper corner of said rail, and with a backwardlyprojecting arm, E, that extends around to the rear of said rail and is furnished with a setscrew, L, to be turned in against the rearside of the rail for securing or clamping the bracket irmly in position thereon.

In Fig. 5, M indicates the spool, S, the spindle, which is supported in bearings on the steprail K and bolster rail N, in the ordinary manner.

T indicates the thread-guide, which is of ordinary form, and is adapted to be raised and depressed by the usual mechanism to traverse the thread from one end of the spool to the other asit is wound thereupon, in the usual manner.

The bobbin is placed in the holder from the top by tipping back the bar F and dropping the bobbin upon the bed or roll D, the end of the thread being then passed under the guard at b2, and carried up through the guide T and onto the spool M, in the manner indicated. The draft on the thread causes the bobbin to revolve within the holder as it lies against the guard-surface b and upon the top of the bed,

while the presser F contines 'it and causes it to rotate steadily and withoutjumping about. If more or less friction is required for giving the desired tension,it can be attained by turning the ball Iso as to screw it more or less to or from the axis of the supporting-bed and presser.

In Fig. 4 I have illustrated a modification of construction adapted to very ne light work, or where light friction and tension is esseetial. In this the bed is made as a roll to revolve freely with the rotary movement of the bobbin. The presser-arms in this case are pivoted on the axis or journals d d at the ends of the rolls, and an auxiliary bar, D', is elnployed for connecting the arms from end to end ofthe bed,andthe tension-adjusting Weight I is Acombined with said auxiliary bar, instead of being combined directly with the bed itself. In this instance I have also shown the weight I made as a nut to traverse on the screw t', which latter is fixed in the bar D', instead of the weight being made the head of the screwstud, asin Fig. 3. I prefer, however, theform shown in Fig. 3 as being the simplest construction.

In cascs where it is desired to use this im-v proved bobbin-holder upon the old style of spooling-machines, in which an inclined spindie-rail exists, it can be done by substituting a supporting-bracket of the form substantially as indicated by dotted lines e2 on Fig. 1 and at e'lon Fig. 3, such bracket being provided with a shank, e3, to be inserted into the hole in said rail where the old bobbin-supporting spindles are'taken out. This form of bracket would be provided with a head having the undercut or dovetailed ears c and the set-screw G, as above described.

My improved bobbin holder can also, when desired, be supported in connection with a round rod, such as is used in many existing machines, by simply making the bracket of a form that will embrace said rod and be attached to it substantially in the manner as are the bobbin-holders such as are now in use.

The advantages incident to my invention are, that the bobbiu-holder is open at thetop, so that the bobbin is in plain sight of the attendant, who can thus the better observe the operation of the work.

Another advantage is that the bobbin is retained steadily in position while allowed a free and easy rotation as the thread is unwound therefrom, so that the spools are wound with an eventension and density, while the degree of tension can be readily varied as desired.

Another advantage, and one incident to the rocking or rolling bed, is that any tendency of the bobbin to become cramped or wedged between the guard-surface b and the supporting-bed surface by the downward draft on the thread, is counteracted by the backward roll or rocking action of the bed,which overcomes the wedging tendency, and instantly relieves any excess of friction due to this cause. As the diameter of the bobbiu decreases, the presserarm friction-bar F swings over toward the surface b of the guard, and the bobbin descends lower between the b'ed D and said surp face b. This somewhat releases the friction as the size of the bobbiu decreases, thus giving a more nearly uniform draft between the large and small diameter. This also insures the more perfect running of or unwinding of the yarn or thread, and by consequent avoidance of frequent breakages greatly lessens the labor of attendance and the loss of time in the running of the machines, which is an item of considerable importance where many bobbinholders and spoolingmachines are in use.

The longitudinal adjustment of the frame upon its supporting-bracket permits of the bobbin-holder being placed in such relation to the guide T that the draft on the thread will be substantially direct and uniform, whether running from the point or the head of the bobbin.

What I claim as of my invention, and desire to secure by Letters Patent, is-

l. A bobbin-holder provided with an axiallypivoted rolling support or bed upon which the bobbin lies, aguard or side plate having an upright surface, as b, against which the bobbin rests, and an upwardly-projecting swinging presser opposite thereto, between which and said surface the bobbin is confined, in the manner described,and permitted rotary movement as the thread is drawn therefrom around the lower edge of said guard, substantially as set forth.

2. A bobbinholder provided with an ax ially-pivoted bobbin-supporting bed, having a swinging presser connected therewith for bearing the bobbin against the side of the holder, and a laterally-projecting stud or arm, in connection with the pivotal axis thereof, having a weight or ball-head disposed at one side of said axis, for the purpose set forth.

3.
