SPOOL-HOLDER.

Application filed July 26, 1913. Serial No. 781,296.

To all whom it may concern:

Be it known that I, MAXIMILIAN J. OTTO, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Spool- Holders, of which the following is a description. 3

This invention relates to spool-holders and particularly to spool-holders adapted to be applied to sewing-machines.

Among the objects of my invention may be noted the following: to provide means, for holding a spool upon the arm of a sewing-machine, which may be readily removed and quickly applied, and which may be applied to any type of sewing-machine now known to me; to provide a spool-holder for sewing-machines for holding spools of thread'thereon in position for supplying thread to the needle or other executive element of the machine, and by means of which the thread may be freely paid off from the spool without fear of entanglement with the spool or spool-holding means; to provide a simple, cheap and effective spool-holding device having frictional means for holding it to the ordinary spoolspindle, or similar support, of the machine, and capable of being raised and lowered on said spindle, or adjusted, or r0- tated thereon for purposes presently described; to provide a spool-holder made of a single piece of resilient material; and to provide a spool-holder which may be adapted to or substituted for the ordinary spo0lholder now found on domestic and manu- .facturing machines.

With the above objects in view and others which will be detailed during the course of this description, my invention consists in the parts, features and elements, and combinations thereof hereinafter described and claimed.

In order that my invention may be clearly understood, I have provided drawings wherein: Figure 1 is a side elevation of a portion of a sewing-machine showingthe application of my invention; Flg. 2 1s a perspective view of my spool-holder; Fig. 3 is a top-plan view showing my spoolholder in place on a portion of the machine, the spool being shown in dotted outline; and Fig. 4 is a view similar to Fig. 3 but showing the parts in a different position.

Referring to the drawings, it will be seen Specification of Letters Patent.

.to be adjusted on the spindle Patented Apr. 27, 1915.

that my spool-holder, in the form which I' have chosen to illustrate for the purposes of this application, consists of a single piece of material. Preferably, I form the spoolholder from resilient wire capable, when bent into the form of my invention, of applying friction to the spindle or pin to which it is adapted.

Referring to Figs. 1 and 2, it will be seen that my spool-holder consists of a securing portion and a spool-holding portion. securing portion comprises a loop or eye 1 formed at one end of the wire and adapted to slide freely over the spindle 2, usually extending vertically from the sewing-machine arm 3. eye which isbent obliquely upward and substantially reversely to form the V-shaped resilient or spring tongue 5 located midway, or substantially so, between the eye 1 The A portion at extends from the 7 and a similar oppositely disposed eye 6,

her 7 of the securing portion. Beyond the eye 6, the wire is extended at an angle as at 8, and then at a right-angle as at 9, to form the spoohholding portion, and then eXtend ed parallel with the member 8, to form the spool-holding pin the spool-holding pin 10'and the securing portion is sufficient to afford space for the largest spool that may be used on any sewingmachine, domestic or manufacturing.

In the several figures it will be seen that the two eyes 1 and 6 are arranged in alinement, or so that they have the same, or substantially the same, center. It will also be seen that the spring-tongue is arranged be tween the two eyes and directly in line, or substantially so, with the centers thereof, so as to press with considerable force or friction upon the spindle 2, to which the holder is applied. Thus, when the securing portion is slipped down over the spindle 2, the latter passes through both the eyes 1 and 6, and the tongue, between the two eyes, frictionally engages the said spindle. The friction between the tongue and the spindle retains the spool-holder firmly upon the spindle, but permits its easy removal and rotation on the spindle. The frictional hold of the tongue also permits the spool-holder so as to locate the free end of the spool-holding pin 10 as far as may be desired from the base of thespool or the arm'2 of the, machine; but, it' should 7 I rangement of the pinlO is" such that its free end will be a distance above'the base, or eye {-1, of the securing portion of theflspoolholder; Thus' when the spool is set upon' V the machine arm w'ith the spindle 10 extend the arm', from becoming ing into the axial passage thereof,thespoolwill be so held as to prevent the thread, should itrfreely' unwind and become loose aboutfthe bottom of the knotted, entangled,

' or otherwise impededlinits free passageto the executive elements'of 4 the machine. a Toapply a spool to the holder, it is only necessary, after having placed the holder in position 'asshown'in Fig. 1, to rotate the holder up'on'the'spindle .2 until the spoolholding pin 10 is beyond the machine-arm sufficiently far to permit the spool 11 to be slid thereon, as shown in Fig. 4. Then the V spool-holderis rotated, by pressure upon the spool, back tojthe position shown in Figs. 1 and 8, so that thespool mayjrest on the machine-arm; It will alsobeunderstood 1 that a fresh spoolof thread may be quickly which event a spindle,

,applied and that anysize spool can be accommodated. r

In some instances the spool-spindle 2, found on a manufacturing machine, may "not" be' adapted to receive my holder, in such as 2, may be substituted for such special spool-spindle.

Having thus described my invention, what I claim and desire to secure by Letters Patcut is: r i 7 1. A spool-holder comprising apair of 3 eyes arranged in alinement and adapted to *Gopies of this pat ent may be obtained for be understood that the ar-' spool and rest upon tongue extending five cents each, by addressing the Washington, D. 0.
