SPOOL-HOLDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 399,095, dated March 5, 1889.

Application filed June 14, 1888. Serial N 277,086. (No model.)

To all whom it may concern.-

'le itknown that. I, CHARLES Louis THOMAS, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented a new and useful Improvement in Spool-Holders and Thread- Protcctors, of which the following is a specification.

My invention relates to a spool holder adapted to he applied to the spool post and spindle to hold the spool and prevent the thread from unwinding more rapidly than the machine takes it up, and thereby becoming entangled with the post or spindle or other parts of the machine and broken.

The invention consists in a certain novel construct ion, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figure 1 is a perspective view of the spoolholder embodying my improvements applied in operative position to the post or spindle of a sewing-machine, a portion of the supportingarm of the machine being shown to indicate the relative positions of the parts. Fig. 2 is a similar view of the device removed from the machine.

Referring by letter to the drawings, A des ignai'es the base-plate of the holder, which is provided with a series of apertures, a a, adapted to engage the post or spindle B of a sewing-machine, the said apertures being prcferablv of varying sizes to fit the various sizes of posts or spindles; and C represents the front side or face-plate of the holder, which is provided with a concavely-curved upper edge and a curved slot, 1), parallel with the said upper edge. The slot is near the upper edge of the faceplate C, and through it is adapted to be passed the thread as it unwinds from the spool E. (Shown in Fig. l.) The spool is arranged between the post or spindle and the face-plate of the holder and parallel wit-h the latter, and it is held from longitudinal movement by the ends F Rwhich tit closely to the ends of the spool.

The slot in the face-plate of the holder is curved, in order to enable the thread as it unwinds from the upper side of the spool to pass horizontally through the slot without undue friction against its sides, and if the spool is unusually large (diametrically) the thread may he carried over the curved upper edge of the face-plate C. The spool cannot become displaced by the motion of the machine. The thread is allowed to run therefrom freely, and the thread cannot unwind more rapidly than the machine uses it, for the reason that the jerking motion of the needlearm does not cause the spool to rotate after the tension on the loose portion of the thread has ceased.

\Vhen the spool is mounted on the post or spindle, as in the ordinary practice, the motion of the needle-arm frequently (in fact almost invariably) causes the spool to rotate after the tension. on the thread ceases, thereby forming a loop in the thread, which drops down around the post or spindle and is liable to become entangled therewith and broken. It will be evident that even if the said loop is formed when the improved holder is employed the thread will not come in contact with the post or spindle, but will hang free.

The holder is shown in the drawings struck from a single sheet of metal or other suitable material; but it will be understood that I may form it by pressure, (thereby providing no joints) or in any other convenient manner known to the art.

Having described my invention, I clain1 As a new article of manufacture, the hereindescribed spool-holder, comprising the baseplate provided with the apertures a a, the face-plate having a concavely-curved upper edge, and provided with the curved slot 1), parallel with its upper edge, and the ends 1*, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

C. LOUIS THOMAS.
