Lette-rs Patent No. 107,288, dated September 13, 1870.

IMPROVEMENT IN vTHRIEIAD-SIFOOLS.

The Schedule referred'to n these Letters Patent and making partlof the same.

. use thc same, reference being had to the accompanying drawing'forming part of this specification.

Figure 1 is a side elevation of a spool without thread, showing thc'appllcation of' my improvement.

Figure 2 is a longitudinal section ofthe same.

Figure 3 is a side elevation of' a spool containing the thread, whose end is secured to thc-spool in accordance with my invention.

Similar letters of' reference imlicate corresponding parts in thescveral figures of' the drawing.

lhe outer end of' thread which is wound upon spools is usually secured in place by being inserted in a notch or slit formed tangentially in one of the flanges of the spools. The formation of this slit weakens the flange of the spool to such an extent that the portion outside the slit next the circumference of the flange is liable to, and frequently does, break off', releasing the end of the thread, and permitting the same to unwind Afrom the spool. It also leaves a rough edge to the flange, againstl which the thread is apt to catch when being unwouud from a sewing-machine, causing hreakages and consequent interruptions in the operation ofsewlng.

My invention has for its object to overcome this difficulty, andconsists in a strip composed ofmetal or other proper material, attached to the spool in such a manner that one end shall 4form a catch, resting against the edge of one of the flanges, tosecnre the f'ree end of the thread and hold it in place against said flange, as will be hereinafter described.

In the accompanying drawing- A is a wooden spool of the ordinary construction.

B is a narrow T-shapcd piece of' metal, provided,

along opposite edges of its shank, with teeth or spurs, bent at right angles to the main portion. y

This deviefis applied to the spool by being placed against the side of' the same, with its T-shaped head resting against the flange, asshown in figs. 1 and 2, and the spurs forced into the wood by any suitable means.

The shape 'of the metallic strip conforms, when in place, to the'coufiguration of thc spool, as shown in fig. 1.

.The thread is then wound upon the spool in the usual manner, andserves to hold the metallic strip firmly in place.

spool, and thereby `forms a catch to receive and hold Athe f'ree end of the thread in place, as shown in lig. 3.

It will be seen that a catch is f'ormcd upon opposite sides of the metal strip, and will, therefore, hold the end of' the thread, wound either to the right `or left upon the spool.

By my invention a catch is applied to a spool which is not liable to become broken, and which will hold the free end 'of' the thread securely in place until rcquired for use, under all circumstances.

I do not confine myself 'to the precise method herein shown for securing the catch to the spool, as other' means may he employed without departing from my invention.

Having thus described my invention,

\Vhat I claim as new, and desire to secure by Let ter Patent, isl A thread-spool, A, provided with the metallic catch B, constructed and arranged to hold the end ot' the wound thread in place, substantially as herein shown and described.
