THREAD IRIEY.[AI1\TIEIR FOR SPOOLING GUIDES.

Application filed February 29, 1924. Serial No. 696,096.

To all whom it may concern:

Be it known that 1, CHARLES F. ROYCE, a citizen of the United States, residing at lVatertown, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in a Thread Retainer for Spooling Guides, of which the following is a specification.

This invention relates. to thread retainers i for spooling guides and particularly to a substantial contact with one another in order to prevent the threads from jumping outwardly between the fingers, it being necessary in applying thethread to the guide to snap it in place between the fingers, so that a retention of the thread in the guide is assured at all tim s.

Another object of the invention is to provide a guide which may be made in one piece and stamped from sheet material adapted to be readily applied to the end of the thread guide provided with the guiding groove, so that the thread may be placed in, or removed from said groove, in an easy and eflicient manner.

The invention also comprehends other objects and improvements in the details of construction and arrangement of the retaining member on the guide for carrying out the above objects which are more articularly described in the, following detailed description and claims, directed to a preferred form of the invention, it being understood however that variations in the specific formation of the retaining member and its association with the guide member may be made within the scope of the descriptionand claims.

In the drawing, forming a part of this application Figure 1 is an end elevation of a thread guide provided with the retaining member forming the subject of this invention, said guide being shown as mounted on the thread board.

Figure 2 is a side elevation of a guide, showing the manner of applying the retaining member thereto.

Figure 3 is a disassembled perspective view of th guide member and the retaining member.

1 indicates the thread board of a spooling machine which is of any desired character usual to the construction of spooling machine and provided with securing means 2 adaptedfor securing the usual thread guide indicated at 3 to said thread board.

The outer end of the thread guide projecting beyond the end of the thread board 1, is rounded as indicated at 4c, and'provided with a guide groove 5, for receiving and guiding the thread in a well-known manner. In the use of guides of this type, which are well. known in the art. it has been found that as the machine is started or stopped, the threads will jump out of the respective guide grooves and that it will require con siderable time in starting up the machine and also in replacing and starting all of the threads in their proper guide grooves in the continuation of the operation of the machine. These guide members 3 are used principally in connection with spooling machine for spooling thread silk on yard and one hundred yard spools.

This invention provides a thread retain ing member, which is indicated generally at 6 and is formed of a single piece of sheet ma terial adapted to be formed into a pair of spaced parallel retaining plates 7 which are connected by a web 8 adapted to seat in a recess 9 formed in one edge of the thread guide adjacent the outer end thereof, so that the outer face of the web 8 and the edge of the thread guide 3 lie in substantially the same plane in order to prevent the threads from catching thereon, which would sliver said threads and give an imperfect spool in the completed winding. The outer free ends of the retaining plates beyond the end of the web 8 are formed with aligned openings 10, adapted when positioned on the thread guides 3 to align with an opening 11 in the outer end of said guide for receiving a retaining groove 12, which rigidly mounts the retaining member on the outer end of the guide. Beyond the openings 10 and beyond the end of the guide, one of the retaining plates is bent toward the other plate as indicated at 13, while the end portions of both plates beyond this bent portion 13 are curved in relative opposite and outward di-, rections as indicated at 14c to provide thread receiving clips. The curved portions are normally in substantial contact with one another as indicated at 15 for preventing the threads from jumping outwardly between the ends of the plates 7, so that it is effectively retained in the guide groove by'the retainingmember, the curved or offset portion 13 being vpro ided in the one plate, so as to position the contact of the plate-to one side of the groove to prevent the thread from catching between'the plates which, under some'conditions might effect a breaking of the thread, which is a very undesirable feature. a

With this retaining member for the thread guide, it will be clear that a thread may be positioned in the guide and retained therein by feeding it through the receiving lip and drawing it down between the contactingportion of the retaining plate into the guide groove '5, so that in the operation of the machine, said'plates will effectivelv retain the threadsin the groove, as the inner faces of these plates are in intimate contact with the outside edges or sides ofthe thread guidev 3, as may be clearly ascertained from an inspection of Figure 1.

Inthis way, it will be seen that the thread is effectively guided and retained in the guide, and that theconstruction of the member is such as'to prevent the 'slivering on breaking of the threads in case it comes in contact with the retaining member.

It is therefore believed to be clear from the above description, that an eflicient and simple retaining member for retaining thread in a spooling guide has been provided, which may be constructed of a single piece of sheet material and efliciently and rigidly connected in cooperation with the outer end of the thread guide.

WVhat is claimed is: V

1. A thread retainer for guides of spooling machines including a member having a pair of retaining plates mounted on the sides of the thread guides and projecting beyond the end of said guide which is formed with a guide groove, said plates being formed to contact beyond the end of the guide and hav; ing outwardly directed lips at the free ends thereof for effectively receiving and retain ingda thread in the guide groove of said gui e;

2. A'retaining member for thread guides of spooling machines comprising a single piece of sheet material forming a pair of spaced parallel retaining plates joined by a web portion connecting the-sides thereof at one end portion thereof, the opposite end portion being formed into'thread receiving lips atthe outer end and adapted for contact with one another for retaining 'athread in the guide groove of a spooling'guide when positioned thereon tocooperate "with said guide.

In testimony whereof]: aiiix mysignature,

- CHARLES ROYCE.
