THREAD CUTTER AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 746,973, dated December 15, 1903.

Application filed March 21, 1903.

To all whom it may concern.-

Be it known that I, JENNIE S. MASON, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Thread Cutters and Holders, of which the following is a specification.

The object of this invention is to provide a new and improved device for facilitating the cutting of thread unwound fromv a spool or bobbin and for holding the cut end of thread remaining on the spool and preventing it from unraveling. I

The invention consists in certain novel features of construction and arrangement of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents an elevation of a spool of thread with my device applied thereto. Fig. 2 represents a plan view of the same. Fig. 3 represents a sec; tional elevation of same, the cutting plane being on line 3 8, Fig. 2. Fig. 4 represents an inverted plan view of the device removed from the spool. Figs. 5 and 6 represent, respectively, an inverted plan and an end elevation of a modified form of my invention, and Fig. 7 represents a side elevation of the same shown as applied to a spool.

In the drawings, 1 is a button or head provided with a tubular spindle 2, having springfingers 3, which are adapted to enter the central aperture 4 of a spool or bobbin 5, said fingers 3 being so constructed as to create a friction upon said spool to prevent accidental displacement of said button and also to prevent the same from being turned relative to the spool 5, except as desired-by the user.

The button 1 has secured thereto or formed thereon a metal strip 6, having its ends '7 bent back upon the body thereof to form V-shaped notches 8, which are adapted to clamp the ends of the thread when inserted therein. The strip 6 is provided with a cutting edge 9 so located that when a thread is unwound from-the spool or bobbin 5 and inserted into the notch 8 the thread will be cut thereby and the end 10 remaining upon the spool will be held securely clamped in the notch 8 until Serial No. 148,835. (No'modeli) I it is desired for use. When a new length of thread is desired, the button 1 is turned relative to the spool 5 so as to produce a slackness of thread, and thuspermit the user to secure a convenient hold thereon to remove the end 10 from the clamping-notch 8. Said button 1 is provided at its center with a recess 11, in which is inserted a lump of sewing-wax 12 for use in waxing the thread when desired. The wax 12 is held in position by prongs 13, as shown.

It will be readily seen that this device forms a very convenient arrangement for any one using sewing-thread, producing as it does in a small space a thread-holder, a thread-cutter, and a device for waxing the thread.

It is obvious that much time may be saved by the use of this device, as by one motion the thread may be cut and the end remaining on the spool securely clamped without handling.

When it is desired to dispense with the wax device, the form shown in Figs. 5, 6, and 7 may be used to good advantage, in which case a single strip of metal 14 is bent to form a stem or spindle 15 to be inserted in the central aperture of the spool, While the ends of said strip are bent outwardly and back upon themselves to form notches 16, the strips 14 being provided with a cutting edge 17 at the apex of each notch.

It is obvious that either the buttons 1 or the stem 2, or both, may bemade of wood or any other material equally as well as of metal, as shown in the drawings.

Having thus described my invention, I claim- 1. An attachment for spools and bobbins comprising a spring-spindle to enter the'central aperture of a spool or bobbin, a piece secured to the protruding end of said spindle and bent back upon itself to form a clamp for the end of the thread, and a knife-edge formed upon said clamp portion.

2. An attachment for spools and bobbins comprising a button provided with a spindle to enter the central aperture of'a spool or bobbin, meaus for preventing the accidental removal of saidspindle from said aperture, a strip secured to said button bent to form a V-shaped notch to hold the end of the thread upon said spool or bobbin, and a cutting edge formed upon the bent portion of said strip.

3. An attachment for spools and bobbins comprising a button provided with a spindle to enter the central aperture of a spool or bobbin, means for preventing the accidental removal of said spindle from said aperture, a strip secured to said button and bent back upon itself to form a clamp for the end of the thread upon said spool or bobbin, and a knifeedge formed upon said bent portion of said strip.

4. An attachment for spools and bobbins comprising a button provided with a spindle adapted to enter the central aperture of a spool or bobbin, means for preventing the accidental removal of said spindle from said aperture, and a cutting-blade secured to the periphery of said button and provided with a portion bent outwardly therefrom to form a clamp for the end of the thread upon said spool or bobbin.

' 5. An attachment for spools and bobbins comprising a button provided with a spindle adapted to enter the central aperture of a spool or bobbin, means for preventing the accidental removal of said spindle from said aperture, a cutting-blade secured to the periphery of said button and provided with a portion bent outwardly therefrom to form a clamp for the end of the thread upon said spool or bobbin, and a Wax-holding recess formed upon said bobbin.

Signed by me at Boston, Massachusetts, this 6th day of March, 1903.

JENNIE S. MASON.
