THREAD CUTTING AND HOLDING ATTACHMENT ron SPOOLS.
Specification of Letters Patent.
Application filed August 17, 1912. Serial No. 715,627.
Patented Nov. 12, 1912.
- To all whom it may on ncem:
Be it known that I, THERESA ISABEL L. BUTTs, a citizen of the United States, residing at Albuquerque, in the county of Bernalillo and State of New Mexico, have invented certain'new and useful Improvements in Thread Cutting and Holding Attachments for Spools, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to improvements in thread cutting and holding attachments for spools and has for its primary object to pro vide a simple device for this purpose which may be cheaply manufactured and is of great convenience and serviceability in practical serviceable in actual use.
WVith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.
For a full understanding of the invention, reference is to be had to the following 'description and accompanying drawing, in which- Figure 1 is a perspective view of a spool showing my improved attachment applied thereto, and the thread held upon the end of the spool; Fig. 2 is a longitudinal section through the spool; and'Fig. 3 is an enlarged perspective view of the attachment removed .from the spool.
Referring in detail to the drawing 5 designates'the ordinary wooden spool upon which the thread is wound. This spool is provided with the usual central longitudinal opening or bore 6.
My improved attachment which is designed for application to the spool is constructed fi'om a single length of flat spring metal indicated generally by the numeral 7 bent upon itself lntermediate of its ends, as shown at 8 to provide normally divergently disposed arms 9 and 10, respectively, the
arm 10 being somewhat greater in length than the arm 9. The end of the shorter arm 9 of the metal strip is bent inwardly toward the longer arm 10 as indicated at 11. The outer end portion of the longer arm-10 is also bent at right angles to the main portion thereof but in an opposite direction to the end 11 of the arm 9 as shown at 12. This laterally extending end 12 of the longer arm normally extends to a slight distance beyond the end of the arm 9 and the extremity thereof is reversely bent as shown at 13 to provide closely engaged portions between which the thread is adapted to be disposed as will be more clearly described in the following description of the use of the attachment. The extreme end of the portion 12 of the arm 10 is again extended outwardly and is upwardly bent from. the reverse bond 13 thereof as shown at 14. This upwardly extend ing extremity is provided with a notch 15 the edges of which are sharpened.
In the use of my improved attachment, the diverging arms 9 and 10 thereof are inserted into the opening 6 of the spool 5 and forced into said opening until the bent end 11 of the arm 9 is disposed inwardly of the end face of the spool. In this inward movement of the resilient arms 9 and 10 of the device into the opening 6 in the spool, the
angular end 11 of the arm 9 is gradually forced laterally into engagement with the arm 10 so that when the device is disposed in its proper position in the spool, the hearing engagement of said angular end of the arm 9 against the arm 10 will force the latter arm 1nto close frictional contact with the wall of the opening 6. It will thus be apparent that the device is retained in its pro er position in the spool opening against liability of its accidental longitudinal movement. The laterally extending end portion 12 of the arm 10 projects outwardly from the opening 6 over'the end face of the spool so that the reverse bend 13 in the portion 12 is located contiguous to the edge of the L spool. After a desired length of thread has been unwound from the spool, the thread is assed over the end of 'the spool and moved into the lapped or reversely bent portion 13 of the holder where it is held against furconstruction'and-manner ofus'e of my 1m- -groved spool attachment w1ll be clearly unessential features or sacri vsame against the shar ened edges thereof.
In this manner the t read may be very easil and quickly out after the desired ortion as been removed from the spool. he end of the thread remaining thereon is securely held soithat the thread will not become unwound. i
From the foregoing it is believed that the erstood.
The device may be easily and quickly attached to or removed from the spool, and provides convenient means, WhlCll is always at hand, whereby the thread may be easily and quickly severed and held upon the spool to prevent unwinding of the same.
Owing to the fact that the ent1re devlce is formed from a single length of metal whlch may be stam ed out by means of a die and readily bent into the desired form, it will be apparent that the invention can be manufactured in large quantities at very small cost.
The attachment is referably constructed bf spring metal, but 1t will be obvious that other material which is capable of accomplishing the desired results may be employed. The invention is, of course, also susceptible-of other modifications in form and proportion without departing from the cing any of the advantages thereof.
Having thus described the invention what is-claimed is:
1. A thread cutting and holding attachment for spools comprlsin a single stri of spring metal bent interme iate of itsen s to provide divergently disposed arms which differ in length, thesaid arms being adapted for insertion into the opening of a spool, the
vlded with a V-shaped notch having sharpened edges, substantially as and for the purpose s ecified.
2. thread holding and cutting attachment for spools comprising a single strip of spring metal bent upon itselfintermediate of its ends to provide divergent resilient arms, one of said arms being longer than the other and provided at its end with a laterally disposed portion, lateral portion of' the arm being reversely bent to provide a clamp for holdlng the end of the thread, the extremity of said arm being extended outwardly from the reverse bend therein and provided with a V-shaped notch having sharpened edges, said laterally disposed portion of the arm being adapted for close engagement with the end face of the spool and extending from the opening therein to the outer edge of the spool, said shorter resilient arm extending entirely within-the opening of the spool and having its extremity angularly bent and adapted for hearing engagement against the longer arm to force-the latter arm into close frictional contact with the wall of the spool opening when the attachment is in posltion therein.
In testimony whereof I hereunto aifix my signature in the resence of two witnesses. T RESA I. L. BUTTS. Witnesses:
