SPOOL-HOLDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 678,756, dated July 16, 1901.

Application filed November 12, 1900. Serial No. 36,248. (No model.)

To all whom it may concern:

Be it known that I, EVERETT E. NORRIS, a citizen of the United States, residing at Randolph, in the county of Cedar and State of Nebraska, have invented new and useful Improvements in Spool-Holders for Sewing-Machines, of which the following is a specification.

My invention relates to spool-holders for sewing-machines; and its object is to provide simple and effective means for insuring the free revolution of spools on sewing-machines and to prevent the breaking or entanglement of the thread that may unwind faster than it can be utilized. 1

It is well known that the thread upon spools supported on the ordinary pin projecting from the arm frequently unwinds faster than it is required for use and is wound around the supporting-pin below the spool and becomes either tangled or broken, thus necessitating the stopping of the machine and the rethreading thereof.

My invention is designed to remedy this defect; and it consists in the improvedconstruction of spool-holder, which will be fully described hereinafter, in connection with the accompanying drawings, which form a part of this specification, and defined in the appended claims.

In the drawings, Figure 1 is a central vertical section of a spool-holder embodying the invention in position upon a sewing-machine arm, and Fig. 2 is a view in perspective of the holder removed from the machine.

The reference-numeral 1 designates the arm of the sewing-machine, from which projects a pin 2, which is slightly longer than the pin ordinarily employed as a spool-holder.

3 designates a disk, preferably of metal, and 4 is a tube rising centrally from the disk 3 and closed at its upper end.

The upper face of the disk 3 is formed with a plurality of concentric shallow grooves 5, into each of which is adapted to be fitted a removable ring, as shown at 6, said rings being of different sizes to fit the difierent grooves and the upper edges of said rings being formed with teeth 7, upon which the lower end of the spool rests, as illustrated in Fig. 1. 5o

The disk 3 is formed with a central opening through which the lower end of the tube 4 extends, and said lower end of the tube is open to adapt the tube to be slipped over the pin 2, so that the upper closed end of the tube i will rest upon the end of the pin and serve as a bearing for the holder as it revolves.

The plurality of concentric circular grooves in the disk 3 and the removable rings fitting therein adapt the device for spools of all pin 2, after which the spool, as shown in Fig.

l, is placed over the tube, the lower end of the spool resting upon the teeth of one of the rin s.

I? will be obvious that the toothed ring which supports the spool, as well as the disk 3, both of which parts revolve with the spool, will effectually prevent the thread from pass ing under the spool and winding around the stationary pin 2, and thus the liability of tangling or breaking the thread in the manner above referred to is entirely obviated.

The upper portion of the tube 4 is externally screw-threaded to receive a thumb-nut 8, which serves to firmly secure the spool in position upon the toothed rings, thus preventing accidental displacement of the spool.

I claim- 1. Aspool-holderforsewingnnachineacomprising a disk; a tube rising centrally therefrom and closed at its upper end; and a ring projecting from the upper surface of the disk to support the spool.

2. Aspool-holderfor seWing-machines,com-

prising a disk having a central opening; a

tube, the lower end of which extends through said opening, said tube being open at its lower end and closed at its upper end; and a ring projecting from-the upper surface of the disk and formed with a toothed edge.

3. A spool-holder for sewing-machines, comprising a disk formed with a central opening and with a plurality of concentric circular grooves upon its upper face a, tube, the lower end of which extends through the disk, said tube being open at its lower end and closed at its upper end; and a toothed ring fitting one of the circular grooves.

4:. Aspoolholderforsewing-rnachinescomprising a disk; a tube rising centrally therefrom closed at its upper end and externally screw-threaded; a ring projecting from the 10 upper surface of the disk; and 2t thumb-nut adapted to engage the threads of the tube.

In testimony whereof I affix my signature in presence of two Witnesses.

EVERETT E. NORRIS.
