DEVICE FOR CUTTING THREAD.
SPECIFICATION forming part of Letters Patent N 0. 579,920, dated March 30, 1897. Application filed November 16 1896. Serial No. 612,391. (No model.)
To all whom it may concern.-
Be it known that I, FRANCIS N. LAWTON, of the town of Summit, Union county, State of New Jersey, have invented certain new and useful Devices for Cutting Thread upon a Spool asitis Drawn for Use, of which the following is a specification Ever since cotton thread, twist, and silks have been wound upon the ordinary form of wooden spools there has been a demand for a simple device placed upon the spool for the purpose of severing the thread as it is unwound from the spool for use. Especially is this desirable With the heavier and stronger grades of cottons and silks, which usually demand the service of teeth, knife, or scissors. Although numerous devices have been invented for this purpose, none seem to have combined a simplicity of form and efliciency of result in sufficient degree to warrant any extensive adoption of the same.
Figure I represents my device, which can be either turned or stamped out of any sheet metal, such as iron, brass, or tin, and which consists of a hollow conical shank 0, having its circular edge at the top turned or rolled over, so as to form a small flange or lip A. The pointin the shank where this flange starts is marked B. The circular edge of this flange is sharpened and turned down ward,thus forming a cutting edge at everypoint in its periphery and having its cutting edge turned downward, Which is the most effective angle for cutting the thread.
Fig. II is a sectional view of the device placed in its proper position on a spool. The shank O is pushed into the hollow shaft of the spool, binding the sides of the shaft tightly until it comes to a fullstop at the sharp bevel marked B. It is there held firmlyin position, leaving a small space between the head of the spool and the cutting edge of the flange A for the purpose of sliding the thread between them before cutting.
Fig. III represents a convenient form of unwinding and cutting the thread. The spool is held in the left hand G and allowed to revolve between the thumb and finger as the thread F is drawn by the right hand H. lVhen a sufficient length has been drawn, the thread is placed between the head of the spool and the flange A. It is then drawn to an angle with the cutting edge and a light jerk severs the thread.
Having described my invention, I make the following claim:
A thread-cutting device for spools consisting of a hollow conical sh anktaperin gthroughout its entire length and having its large end curled sharply overand downward at an acute angle with its shank and terminatin gin a continuous cutting edge, substantially as specified.
FRANCIS N. LAlVTON.
