ATTORNEY Patented Nov. 4, 1941 UNITED STATES- OFFICE THREAD CUTTER Leo J. Geier, St. Henry, Ohio Application September 11, 1939, Serial No. 294,285
1 Claim.
This invention relates to improvements in thread cutters, particularly to an attachment for sewing machines or the like and it is the principal object of my invention to provide a thread cutter which can readily be attached to a spindle of the sewing machine and operated to cut the thread at any desired time and portion.
Another object of my invention is the provision of a manually operated thread cutter of comparatively simple and inexpensive construction, yet durable, and highly efiicient in use.
A further object of my invention is the provision of a thread cutter, preferably for sewing machines equipped with a spindle which is attached by means of a pair of jaw clamps to the spindle of the sewing machine so that it may conveniently be removed therefrom and replaced or repaired.
A still further object of my invention is the provision of a thread cutter attachment for sewing machines including a stationary jaw and a movable jaw having suitable cutting edges cooperating for cutting the thread and equipped with an operating handle, the movable jaw being returnable by the action of a spring after each cutting operation into its original position.
These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be specifically defined in the appended claim.
In the accompanying drawing forming a mate rial part of this disclosure:
Fig. 1 is a side elevation of the attachment constructed according to my invention, partly in section and attached to the spindle of a sewing machine.
Fig. 2 is a side elevation of the cutter jaws partly in section on line 2-2 of Figure 1.
Fig. 3 is a view similar to Figure 2, the section being taken on line 3-3 of Figure 1.
Fig. 4 is a fragmentary side elevation of one of the cutter jaws partly in section on line 4-4 of Figure 1.
As illustrated, to the spindle l6 of a sewing machine or the like, a spindle II is removably and exchangeably attached by means of the jaw clamps l2, l3, the clamp part I2 forming an integral part of the spindle II, while the clamp member I3 is held thereto by means of the screws l4, I respectively.
The thread cutter attachment, generally designated I6, is held to the lower, reduced portion I! of the spindle II and held thereon by means of a nut l8 screwed upon the threaded end 19 of the spindle l I.
The stationary jaw 20 is connected by means of the peg 2| to the movable jaw 22 having a certain play in an arcuate slot 23. The movable jaw 22 has formed therewith a handle 24 and a chamber 25 in which a spiral spring 26 is anchored at its ends, as at 27, 28 to opposite walls of the chamber 25.
The operation of my thread cutter will be entirely clear from the above description by simultaneous reference to the drawing, and it will be clear that after clamping the spindle II to the machine spindle H], the thread can be cut by the operation of the movable cutter jaw by means of its handle against the stationary jaw, and that after each operation the spring will automatically return the movable cutter jaw into its original position ready for another cutting operation.
It will be understood that I have described and shown the preferred form of my device only as an example of the manypossible ways to practically construct the same, and that I may make such changes in its general arrangement and in the construction of its minor details as come within the scope of the appended claim without departure from the spirit of my invention and the principles involved.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
In a thread cutter attachment for sewing machines, a stationary cutter jaw at the end of the sewing machine spindle, said stationary cutter jaw having an arcuate slot, a movable cutter jaw having a pin engaging with a certain play the arcuate slot in said stationary cutter jaw, said movable cutter jaw having a chamber formed therein, a spiral spring in said chamber surrounding said spindle and anchored with its ends to opposite walls of said chamber, a handle on said movable cutter jaw integral and in alignment therewith and extending laterally therefrom to guide it against said stationary cutter jaw, said spring returning said movable cutter jaw into its position of rest after each cutting operation.
LEO J. GEIER.
