SPOOL-SUPPORT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 589,053, dated August 31, 1897.

Application filed October 9, 1896.

To all whom, it may concern:

Be it known that I, HELEN LOUISA \VEB- STER, a citizen of the United States, residing at Wellesley, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Spool- Supports for Sewing-Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same, and in which like numerals of reference designate the same parts wherever found throughout the several views.

This invention relates to spool-supports for sewing-machines; and the object thereof is to provide an improved device of this class which is designed to prevent the thread from wrapping around the ordinary support of the spool on the machine and thereby being broken in case it should leave the spool, and thisis accomplished by my device, which is designed to receive the thread as it drops from the spool, and as the device turns with the spool the thread is unwound without any break and afterward guided onto the spool.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a side View of my improved spool-support; Fig. 2, a central vertical section thereof; Fig. 3, a vertical sectional view.

of a modification.

In the drawings forming part of this specification, reference being made to Figs. 1 and 2, I have shown at 5 the usual pin which is connected with the arm of a sewing-machine by means of a screw-threaded shank (Tor other suitable device, and said pin is provided with a circular disk or plate 7, on which the spool ordinarily rests; and in the practice of my invention 1 provide a supplemental support, which consists of a tapering or conical I tubular portion 8,which is mounted on the pin 5 and which is provided with a circular base flange or plate 9, the diameter of which is equal to or greater than the diameter of the end of the spool. I have also shown in Figs. 1 and 2 a spool 10, which is mounted on the supplemental support 8, and in practice I provide an auxiliary holder 11, which is also conical in form and provided with a circular base plate or flange 12, the diameter of which Serial No. 608,335. (No model.)

is equal to or greater than the diameter of the end of thespool', and the auxiliary holder 11 is provided with a central bore 13 and is inserted into the upper end of the spool, the pin 5 passing therethrough, and the apices of the conical supports 8 and 11 are smaller in diameter than and adapted to enter the bore of the spool.

It will thus be seen that the spool when in position does not come in contact with the pin 5 or the plate 7, but rests upon the conical support 8 and is centered by the auxiliary holder 11. The holder-11 and the supports 8revolve on the pin 5 with the spool, and if at any time the thread should become unwound, so as to slip off the spool below or above it, it will be wound either on the conical support 8, between the lower end of the spool and the base 9 of said support, or on the auxiliary holder 11, between the upper end of the spool and the circular head 12, both of which revolve, as hereinbefore described, and there will therefore be no danger of breaking the thread, and as the thread is unwound from either of their parts it is again guided onto the spool.

In spool holders or supports for sewingmachines as usually constructed the thread when it becomes detached from the spool will be wound on the pin 5, and since this is stationary the thread is inevitably broken, as is well known by all those familiar with this class of devices; and the object of my improvement is to prevent this breaking of the thread, and my improved support is per- I fectly adapted to accomplish this result.

The diameter of the conical support 8 or the lower portion thereof is greater than that of the bore of the spool, the difference between the diameters of the top and bottom of the cone being from one-eighth to one-quarter of an inch, and thus the device accommodates itself to spools of different sizes, and this is also true of the auxiliary holder 11.

In Fig. 3 I have shown a modification in which I employ a central tube 14, the base of which is provided with the conical tubular support 18, having a circular base 19, which rests,in practice,on the disk or plate 7, (shown in Figs. 1 and 2,) and the spool in practice is mounted on the tube 14 and rests on the circular portion. In this form-of construction on said pin 5 the tube 1t projects upwardly through the spool and is provided with the auxiliary holder 11, which is the same as the holder 11 shown in Figs. 1 and 2, and which is detachably connected with the upper end of the tube, and this form of support operates in the same manner as those represented in said Figs 1 and 2.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. Aspool-holderforsewing-machines,cousisting of a stationary upright rod, and two cones which are adapted to turn thereon, and one of which is inverted, said cones being also provided with a flat circular base flange or plate, and the apex of each being of less diameter than the bore of the spool and the base thereof of greater diameter, and the apex being adapted to enter the ends of the spool, substantially as shown and described.

2. Aspool-holderforsewing-machines,eonsisting of a stationary upright rod, and two cones which are adapted to turn thereon, and one of which is inverted, said cones being also provided with a flat circular base flange or plate, and the apex of each being of less diameter than the bore of the spool and the base thereof of greater diameter, and the apex being adapted to enter the ends of the spool, and a tube by which said cones are connected, and with which one of said cones is detachably connected, substantially as shown and described.

In testimony that I claim the foregoing as in y invention I have signed my name, in presen cc of the subscribing witnesses, this 3d day of Octobcr,-189O.
