SPECIFICATION farming part of Letters Patent No. 318,923, dated May 26, 1885.

Application tiled December l2, 188i.

.To @ZZ whom, t may concern.-

Be it known that I, ALFRED B. Monsn, of South Easton, county of Bristol, State of Massachusetts, have invented an Improvement in Sewing-Machine-Thread Unwinders, of which the following description, in connection with the accompanying drawing, is aspecitication, like letters on the drawing representing like paris.

This invention has for its object to provide a simple and easily-operated device by which to unwind thread, the said device being readily applicable directly to the spool con-taining the thread which is to be unwound.

My improved device consists, essentially, of a sleeve, the foot of which is inserted into the open center of the spool, the said sleeve receiving a spindle, to which is rigidly attached the nn\vintling-arni, preferably formed of wire coiled about the spindle, and brazed or soldered thereto, such construction enabling light-weight spring-wire to be used for the unwinding-arin, and yet afford averystrong and durable connection with the spindle.

The drawing represents one ot' my threadunwinders applied to a spool of thread, the spool being shown broken ont to better dis! play the spindle.

rlhe spool A, containing thread to be used in a sewing-machine, is bored centrally, as usual, and will be held in place when in use by placing the lower end ofthe spool on a pin in any usual manner. The sleeve B of my irnproved nnwinding device has a foot, b, which is of suitable diameter to enter the central bore or hole at the top of the spool; and to enable the said sleeve to be retained in position with relation to the spool I have slotted the foot, and placed in the said slot a spring, b', one end of which is left free. A part of the said spring normally extends outward beyond the periphery of the foot, where it acts frictionally against the spool to prevent the withdrawal of the sleeve, except by the eXertionof considerable force. The foot never rotates in the spool, and maybe applied readily to any usual spool. The upper end of the sleeve is bored to receive the spindle @,which at its upper end is provided with a thread-guiding (No model.)

eye, o. The spindle near its lower end is provided with an annular groove, c2, which receives a pin, e, by which to keep the spindle in the sleeve, but yet enable the spindle to rotate freely. rIhe thread-unwinding arm cl, iliade preferably of tine steel wire, has at its lower end a thread-receiving eye, d', the upper end of the said wire being wrapped in one or more coils about the spindle, to which it is brazed or soldered, such inethod of connecting the unwinding-arni with the spindle being very strong, and enabling a sxnall wire to be used for the arm d. Thread from the spool is conducted through the eye ci', thence through the eye c to the usual thread-guide eyes and tension device of the sewing-machine with which the spool is to be used. The shoulder b2 of the sleeve meets the end of and prevent-s the entrance of the t'ootb too i'ar into the spool.

I claiml. The sleeve of the threadnnwinding device, adapted to be inserted vinto aspool, and bored at its end for the reception oi a spindle, combined with a spindle inserted therein provided with a guide-eye, and having a springwire arm, d, provided with a guide-eye, and coiled about and soldered or brazed to said spindle, substantially as described.

2. The sleeve provided with the foot to enter the spool, and with aspring to engage the spool, and with a hole i'or the reception of the spindle, combined with the spindle having a thread-guiding eye, and with the spring-arrn having a thread-guiding eye, snbstantiall y as described. y

3. The sleeve having the foot to enter the spool, and the spindle entered into the said sleeve, combined with the spring-arm, it having a thread-guiding eye at one endand coiled at its other end about the spindle, substair tially as described.

In testimony whereof I have signed my name to this specification in presence ot' two subscribing witnesses.

ALFRED B. MORSE.
