COTTON STAND FOR SEWING MACHINES Filed April 25, 1953 I7. flSciulZo Patented Apr. 17, 1934 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to devices for holding cotton thread in association with sewing machines and particularly for use on sewing machines used in factories where the thread is Wound in the form of cones.

One of the objects of the invention is to provide a cotton stand or holder for these cones of thread which will entirely house the thread and protect it from the action of sunlight if the machine is left standing for any considerable length of time without being used and which will further protect the thread from drafts or the action of Wind which often causes the thread to become tangled With other parts of the machine.

A further object is to provide a cotton stand or holder which will prevent the thread from coming in contact with the work while the work is being removed from the machine, thus avoid- 'ing either an entanglement of the thread or a breakage of the thread.

A further object is to provide a device of this character which includes a thread tube or tubes and provide at the end of each tube an eye so formed as to hold the thread ready for use after the thread has been cut but which is so formed as to normally permit the ready movement of the thread through the holder.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a fragmentary elevation of the sewing machine and cotton stand constructed in accordance with my invention;

Figure 2 is an enlarged longitudinal section through the housing;

Figure 3 is a transverse section thereof;

Figure 4 is a horizontal section on the line 44 of Figure 2;

Figure 5 is a detailed sectional view on the line 5-5 of Figure 3;

Figure 6 is a vertical sectional view of the thread guard;

Figure 7 is a face View of the guard.

Referring to this drawing, 10 designates a housing or casing which is illustrated as generally speaking elliptical in longitudinal cross section and which is divided into two compartments by the vertical partition 11. The casing is provided with two openings 12 and hinged to the top 13 of the casing are two conical caps or covers 14, these being hinged at 14*. Suitable latches may be provided for holding these covers closed. Each cover extends upward in the form of a cone and from the apex of the cone extends a tube or thread guide 15 or 15 Each thread guide has an interior diameter of about one-fourth of an inch and opens at the exact center of the conical cover 14. This tubular guide 15 has a longitudinally extending slit for its entire length designated 16, this slit being in the top center of the tubular portion and. at its junction with the conical portion 14, this slit is expanded at 17. This permits the thread from the cone to be drawn out through the opening 17 and then the slot 16 permits the thread to be inserted in the guide. Attached to the extremity of the tubular guide 15 is a thread saver designated 18 whose shank 19 is attached to the top of the tubular guide 15 so that the eye 18 of the thread saver is directly in line with the passage through the tube. It may be remarked that the slit 16 of the tube has a diameter of onesixtieth of an inch and is just wide enough to allow the thread to be easily drawn into the tube. The eye 18 of the thread saver can be made of any smooth metal or wire. This is circular in cross section for the greater portion of its circumference but at a point coincident with the slit in the tube 15, the two opposite portions of the eye are pressed together at 20 or flattened closely enough to hold the thread. This flattened part is sharp on the outside or toward the machine and dull toward that portion of the eye opposite the tube.

The cone of thread is supported within each of the compartments by means of a metal pin 21 about four inches high. The casing 10 is divided, as before remarked, into two compartments by the partition 11 and there'is a cap or cover 14 for each of these compartments and from each cap or cover extends tubular guide 15 or 15 One of these guides 15 is designed to feed the thread to the top guard of the sewing machine as indicated generally in Figure 1 while the other guide 15 is bent so as to feed the thread to the bobbin winder of the machine. The first named guide is relatively short and extends over the top of the machine while the second named guide extends downward and laterally.

Preferably there is disposed between the bobbin winder of the machine and the corresponding tubular guide 15 a guard designated 22. This guard is about six to eight inches in length and two to three inches high. The guard is formed with a longitudinally split tube 23 at its upper edge and the guard serves as a guard against the revolving belt of the machine and as a guide for the thread to the bobbin winder after the thread has left the tube of the cotton stand.

It will be seen that the thread for the bobbin winder and for the top guard of the sewing machine is entirely enclosed and that the threads from the two reels of cotton are guided to their proper position by tubular portions or extensions of the cotton stand so that the chance of the work coming in contact with the thread, catching on it and breaking it is to a very considerable extent eliminated and that this gives the operator greater freedom in moving around his machine. Furthermore drafts will not cause the thread to be forced toward the machine and into engagement with some moving part thereof, thus entangling and breaking the thread. It is also to be seen that the thread saver will hold the thread ready for use while at the same time the sharp edge on the thread saver permits the thread to be readily cut whenever desired. When the thread is in the jam 20 of the eye 18, it takes a sharp upward pull to cut the thread.

While I have illustrated the casing 10 as being provided to form twocompartments, each compartment for a single cone, it is to be understood that it may be made to house only a single cone and may be placed either on top of the table or beneath the table with the stand inserted through the table with the conical top extending above the top of the table.

What is claimed is:

1. A thread stand of the character described, comprising a casing having a top hinged to the body of the casing, and a thread guiding tube extending to the apex of the conical top, extending upwardly, outwardly and downward in a curve, the upper wall of said tube being longitudinally slotted throughout its entire length, the slot being slightly greater in width than the diameter of the thread to be used therewith, the slot at its junction with the apex of the top being enlarged.

2. A thread stand of the character described, comprising a casing having a top hinged to the casing, means disposed within the casing for supporting a spool of cotton therein, a tubular thread guide extending from the apex of the top, the guide extending upward, outward and downward, and an eye carried by the extremity of the guide and spaced longitudinally therefrom, said eye at its outer end remote from the axis of the tube being flattened to form a V-shaped portion.
