5 Claims.
This invention relates to darning devices for use with sewing machines and more particularly to an improved thread-holder which may be attached to an operative part of the sewing machine for the purpose of winding thread or yarn thereon.
Another object of this invention is to provide a winding device which may be quickly and easily attached to and detached from the balance or hand wheel of the ordinary household sewing machine, and to which the thread-holder may be attached for the purpose of winding thread thereon.
With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawing of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.
Fig. 1 is a perspective view showing the threadholding device being used with a household sewing machine for the purpose of darning.
Fig. 2 is a perspective view of the balance wheel of the machine illustrating the winding of thread on the holder.
Fig. 3 is a side elevation, partly in section, of the thread holder and winding device.
In the embodiment of the invention selected for illustration the thread holder comprises a yoked member having arms l and l l and a yoked portion I2 bent upwardly to form a handle. The arm 10 is formed with kerfs l3 and 14 into one of which the beginning end of the thread may be inserted at the start of the winding operation. At the end of the winding operation the finishing end of the thread may be inserted in the other kerf.
The balance-wheel l5 of the machine is driven by an electric motor, or any other suitable means, and is adapted to be clutched and unclutched to the main shaft of the machine through the medium of the usual and well known clutch of the type illustrated and described in the patent to W. J. Peets, No. 1,934,373, Nov. 7, 1933. To the clutchscrew l6, which rotates with the balance-wheel IS, a disk i! is detachably secured by means of three spring-wire clips 18 which are U-shaped, each having one of its ends fixed in a suitable aperture in the disk I? and its other end bent so that it overlies the periphery of the clampscrew [6 and engages the inner marginal edge thereof.
The outer face of the disk I! is provided with apertures which are adapted to receive the arms I0 and ll of the thread-holder and one of the arms may be locked in position by means of a set screw 20. From the foregoing it will be obvious that the beginning end of the thread may be inserted in one of the kerfs and the balance-wheel rotated at a low rate of speed so that the thread may be guided to and wound about the threadholder, as illustrated in Fig. 2. After the thread has been wound on the holder the finishing end is inserted in the other kerf.
My improved darning device is used in the following manner: The material to be repaired is placed in a darning ring 2! and the darning ring with the material therein is placed on the workplate 22 of the ordinary household sewing machine. The thread-holder, with the thread wound thereon in parallel relation, is then placed over the hole to be darned. The machine is operated and the darning ring and holder are moved back and forth by hand so that the threads on the holder are stitched to the marginal edge of the hole by lines of stitches running at right angles to the lengths of thread on the holder. After the sewing operation has been completed the holder is grasped by the handle and pulled towards the operator so that the arms In and H slide out of and release the looped ends of the thread. The looped ends of the thread may then be sewed down, or, if desired, cut off with a pair of scissors.
Having thus set forth the nature of the invention, what I claim herein is:
1. An attachment for sewing machines comprising, in combination, an apertured disk attachable to the balance-wheel of a sewing machine, a thread-holder having spaced arms which are received in said apertured disk, and means for locking the arms in the disk.
2. An attachment for sewing machines comprising, in combination, an apertured disk, springarms carried by said disk and adapted to yieldingly engage the clutch-screw of a sewing machine balance-wheel, and a thread-holding member having limbs which enter the apertures in the disk.
3. An attachment for sewing machinescomprising, in combination, an apertured disk, U- shaped spring arms carried by said disk, said arms being adapted to yieldingly hold said disk on the clutch-screw of a sewing machine balance wheel, and a forked shaped thread-holder having arms which extend into the apertures in the disk.
4. A darning attachment for sewing machines comprising, a member having spring arms which are adapted yieldingly gage the clutch screw for the balance Wheel of a sewing machine to cause said member to rotate with said clutch screw, a U-shaped thread-holder having spaced arms about which thread may be wound and a yoked portion bent upwardly to form a handle, and means for detachably securing said thread holder to the member carried by the clutch screw.
5. A darning attachment for sewing machines comprising, a member haw'ng spring arms which are adapted to yieldingly engage the clutch screw 10 limbs to said member.
for the balance wheel of a sewing machine to cause said member to rotate with said clutch screw, a U-shaped thread-holder having spaced arms about which thread may be wound and a yoked portion bent upwardly to form a handle,
5 and means for detachably securing the free ends of the limbs of said thread-holder to said member, said last named means comprising apertures formed in said member for receiving the free ends of the limbs and a screw for clamping one of the WILLIAM HOFGESANG.
