HARRY PALMER LEE, OF STONINGTON, CONNECTICUT.

SWIFT OR REEL.

SPECIFICATION forming part of Letters Patent No. 612,971, dated October 25, 1898.

Application filed March l, 1,898.

To @ZZ `whom it may concern.:

Be it known' that I, HARRY PALMER LEE, residing at Stonington, in the county of New London and State of Connecticut,hav'e invented certain new and useful Improvements in Adjustable Swifts, of which the following is a specification.

My invention relates to swifts, and has for its object to produce an adjustable swift eX- pressly adapted for winding-machines where silks, cottons, or any other materials are wound. To this end my invention consists in the construction hereinafter set forth and claimed.

My invention will be understood by referring to the accompanying drawings, in which- Figure 1 is a sectional view of the hub of my newly-invented swift. Fig. 2 is a side view of the hub, showing the swift partly expanded-that is to say, adjusted. Fig. 3 is a side view, partly in section, the section being taken on the line 3 3 of Fig. 2 and showing the swift more fully expanded and likewise showing the line l l, on which the section of Fig. l was taken when the swift was in its closed or unexpanded condition. Fig. 4 is a section on line 4 4 of Fig. 3, looking in4 the direction of the arrow; and Fig. 5 is a section on line 4 4 of Fig. 3, looking in the direction of the arrow 5.

In the drawings, c. are stir-rups or threadreceiving means, each of which is carried by a plurality of arms b c, which are jointed together at d and pivotally connected to the disks or carriers e f, respectively, each of which disks is connected to a part of a hub g h, whose parts are movable with respect to each other. These disks are preferably corrugated, as shown. The arms b c bear the relation of spokes to the hub. The disk e is carried upon the part g and the disk f is carried upon thepart h, the said hub being secured together by a shaft-1I, shown in the present instance as a bolt. The parts are held from rotating upon each other by a frictional bearing comprising a spring j, contained in a cavity 7c in the part 71,. The part h is likewise shown as provided with an annular groove Z, in which a lug m is provided, which lug is adapted to coperate with a pin ln, carried by the disk e. The stirrups a are Serial No. 672,148. (No model.)

preferably bent up of wire 'and preferably consist of a horizontal wire l, provided with the upwardly-projecting bights or bends 2, flanked by the upward bends 3, forming the notches or recesses 4, from which the ends 5 project downward and are united at the joint d. As before explained, the supporting-arms b c of each of these stirrups are connected to opposite disks or carriers g h, which disks or carriers being rotatable with respect to each other will bring the ends of the said arms b c nearer to or farther from each other, and consequently will expand or contract the swift by moving the stirrups outwardor inward.

By referring to Figs. land 2 it will be noted that the arms b are pivotally secured to the disk e, while the arms c are pivotally secured to the disk f, so that as the disks are rotated with respect to each other the ends of component pairs of arms b c will be brought nearer to or moved farther from each other, thereby expanding or contracting the swift. For instance, the arms b c which support any individual stirrup are shown in Fig. l at about two hundred and forty-eight degrees apart, whereupon the eifective circumference of the swift is represented by the dotted line in the said gure. the arms h c are shown as about one hundred and thirty degrees apart, the swift has been thereby expanded, so that the effective circumference is that represented by the dotted line in this figure, and so likewise of Fig. 3, where the disks have been further rotated, so as to bring the ends of the arms b c still nearer together and further expand the swift. The notches or jogs 4 are for the purpose of providing a resting-place or bearing for the loop of cord or elastic 6, which may be placed therein, so as to thereby afford a more yielding bearing for the thread when it is being unwound from the swift, it being necessary when operating with tender thread, such as some kinds of silks, that the swift should yield a little in order to obviate the danger of breaking the thread.

The hub h g, when the swift is used on winding-machines, will serve as a` shaft for the swift and may be formed at the outer ends g h to go in bearings wherever desired.

It will be obvious that the device may be used as areel, and it is to be understood that In Fig. 2, however, where IOO Wherever I have used the Word swift I mean to thereby include reeL What I claim, and desire to secure by Letters Patent, is-

l. A swift or reel, having a hub, arms extending therefrom and provided with stirrups ct bent up of Wire and having recesses 4 and with yielding loops or cords G resting in the said recesses.

2. In aswift, the combination of a hub having a plurality of movable parts, plates e f carried by the said movable parts and provided with arms b c pivoted to the said plates joined at their extremities and provided with thread-supporting means, substantially as described, carried thereby, one of the said parts of the hub being provided With the recess Z and the other of the said parts being provided with the pin fn, entering the said recess l and a stop 'm for receiving the impact of the pin n.

3. In a swift, the combination of a hub having a plurality of movable parts, plates e f carried by the said movable parts and provided With arms b c pivoted to the said plates joined at their extremities and provided with thread-supporting means, substantially as described, carried thereby, one of the said parts of the hub being provided with the recess Z and the other of the said parts being provided With the pin n entering the said recess Z and a stop m for receiving the impact of the pin a, combined with a spring 7c carried in a recess j of one of the parts of the hub.

4. In a swift, the combination of a plurality of thread-supporting means, a plurality of plates e f, arms b o secured by their extremities to the said plates and to each other, whereby an expanding reel is produced, substantially as described, and a hub provided with a plurality of movable parts, each of which parts carries one of the plates e f and a spring lo intervening between the said movable parts and adapted to frictionally hold the same from turning on each other, substantially as described and for the purposes set forth.
