THREAD CUTTER FOR SHOE MACHINES.
Applicatcn filed July 6, 1922. Serial No. 573,146.
To all whom 'it may concern.'
Be it known that Romina G. VINDHAM, a citizen of the United States of America, residing at Sayre, in the county of Beckham and State of Oklahoma, has invented new and useful Improvements in Thread Cut-ters for Shoe Machines, of which the following is a specification.
The object of the invention is to provide a simple and efficient means for severing a thread of a shoe sewing machine at the end of the stitching operation without resorting to the use of a separate knife or shears for that purpose; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a view of a thread cutter embodying the invention applied in the operative position to a sewing machine arm.
Figure 2 is a detail view in perspective of the cutter detached.
The device embodying the invention consists essentially of an attaching plate 10 with which is integrally connected an upstanding car 11 having a horizontally extended tongue 12 forming a knife blade of which the cutting edge 13 .is bounded by a terminal lip lei servingto prevent thel thread from slipping from the end of the knife, blade without be.- ing severed.
The device is designed for attachment to a shoe sewing machine particularly of the Singer' type, although applicable to 1nachines of other types, and should be attached to the machine under the arm which carries the bobbin so as to be within convenient reach at the conclusion of the stitching operation for drawing the thread across the knife edge which is preferably beveled on one side only.
At the completion of the stitching operation the needle should be raised far enough so as to remove it from engagement with thc shoe and thereupon, after raising the presser foot, the thumb should be placed on the last stitch and the shoe moved forward until the blade of the cutter is reached whereupon by a lateral movement to engage the bobbin thread with the blade of the cutter the shoe may be drawn back until the thread is severed. In other words with a cutter constructed and arranged as indicated a comparatively slight movement forward to effect engagement of the thread with the cutter, followed by a return or backward movement hooking thethread over the edge of the cutter is sufficient to sever the thread without the loss of time incident to the use of a separate cutting means and without the inconveniences involved in reaching for a separate cutter which in practice is subject to misplacement or displacement by the work on the machine.
Having described the invention, what is claimed as new and useful is In combination with a sewing machine having a bobbin carrying arm, of a thread cut-ter consisting of an attaching plate secured on the under face of said arm adjacent the end and provided with an upstanding ear having a horizontallyr extending tongue forming a knife bladeysaid tongue being bounded at the extremity by a terminal lip serving to prevent the thread from slipping from the terminal end of the tongue.
In testimony whereof he afliXes his signature.
EQMIE Gr. VINDHAM.
