WILLIAM A. FINN, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-THIRD TO FRANCIS H. MOCORMACK, OF SAME PLACE.

SPOOL.

SPECIFICATION forming part of Letters Patent No. 594,989, dated December 7, 1897.

Application filed February 8, 1896- Serial No. 578,486. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM A. FINN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Spools, of which the following is a specification.

My invention relates to improvements in spools, spindles, or reels intended to hold cotton, silk, thread, or other similar material, especially to that class of devices which are designed to prevent the thread from being unintentionally unwound.

The objects of my invention are, first, to prevent the unintentional unwinding of the thread when not in use; second, toprovide a device by which the thread may be conveniently fastened both when the spool has been wound to the desired length by the manufacturer and afterward when the spool is in use; third, to provide a device by means of which the thread may be fastened and separated when desired; fourth, to provide a device, as aforesaid, which may be formed integrally with the spool without material additional expense or labor. Iattain these objects by the devices hereinafter described and claimed, as follows:

Heretofore spools for holding thread and other material have been made or used with a small slit or notch in the head of the spool in which the end of the thread was inserted after the spool has been wound by the manufacturer to the desired amount and length, and thus necessitating the making of the slit or notch and the diflicultyof placing the thread therein, all of which my invention is designed to remedy. The slit being so small and being fixed at a certain point it is impracticable to reinsert the thread in the same ence refer to similar parts throughout the various figures.

Figure l is a side elevation of the spool. Fig. 2 is a longitudinal section of the spool through its axis. Fig. 3 is an end elevation of the spool. Fig. 4 is a sectional view showing the inside surface of the flange convex.

Referring to the figures, A is a spool; a and a, the heads thereof; B, an annular flange or disk integrally formed with reference to and a part of the spool; 19, the outer or external surface of the flange; b the inner surface; b the edge thereof; 0, an annular angular aperture between the flange B and the head a; D, the thread.

The annular flange B may be made with an internal annular bevel converging toward the axis of the spool until it intersects the surface of the head.a,-with the angle between the flange and the head quite acute, or the surface of the flange may be convex with a large radius in comparison with the diameter of the flange, forming a bight composed of the head of the spool and the inner surface of the flange in the annular aperture 0. The

edge b may be made sharp in order to cut 7 the thread.

The operation of my device is as follows: The thread or other material in the first instance is wound upon the spool to the quantity required, and the end is inserted in the annular aperture by slipping it over the head of the spool and between it and the flangeand pulled toward the axis of the spool, where the side of the head and the surface of the flange grip or bite the thread and hold it firmly. The spool is then ready for sale and use. In using the spool the thread is removed from the aperture, and when the amount required is ascertained and detached the thread is again placed in the aperture, as aforesaid, and the spool may be cast aside.

When the spool is made of hard wood or the improvement made of metal, the edge b can be made sharp enough to cut the thread or other material as follows: After the amount of thread to be used is ascertained it is inserted in the aperture, as shown in Fig. 3, and

2. A new article of manufacture,a spool provided on the face of one its heads, with an annular flange beveled under and internally at an acute angle to the face of said head, to form a bight to receive and hold the loose end of the thread, substantially as described.

Signed at the city of New York, in the county of New York and State of New York, this 5th day of February, 1896.
