THREAD-130ARD-GTJ'IDE-VIRE HOLDER.

To aZZ whom it may concern-p Be it known that I, FREDERICK S. CUL- VER, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Thread-Board- Guide-lVire Holders, of which the following is a specification.

This invention pertains to certain new and useful improvements in thread board guide wire holders, and the primary object thereof is to improve and simplifythe finger head construction and to provide new'and improved means for positively holding the head either in operative or inoperative position, which means is of simple and efficient character, and which allows the head to be easily moved from one position to the other.

Further, the invention resides in certain details of construction and combination of parts, which. will be more fully set forth in the course of the following specification- In the drawingsFigure 1 is a side eleva- 'tion of the invention applied to a thread board rail, the latter being shown in fragment and in section, the finger head being illustrated in operative position. F ig. 2 is a similar view showing the head inraised or inoperative position. Fig. 3 is a bottom plan view of the invention, in detached relation to the board, and Fig. 4; is a perspective view of the head, the guide wire being omitted.

In accordance with the present invention the head is preferably formed of a section of sheet. metal, bent to form a trough-like structure possessed of a body 1, sides 2, a front end 3, and a rear wall 4:, thelatter extending beyond the free edges of the sides 2 and formed of a continuation of the body. The front end 3 is provided with a concave seat 5 in which the shank 6 of the wire thread guide 7 is received. The rear or inner end of the shank 6 is bent into a U-shaped portion 8, the legs of which portion en age the inner faces of the sides 2 to thereby old the shank against lateral movement relative to the head in'which regard the seat 5 also acts to further prevent lateral movement of the front end portion of the shank 6 as is evident from Fig. 3 of the drawings.

The tail of the holder is formed of a member 9 which is secured to the under face of the thread board rail T and which has a pair of perforated forwardly projecting cars 10, which latter receive the rear ends i913. Serial iv fvsgisc.

of thesides 2, of the head, said rear ends having apertures 11 that aline with the perforations of theears lO-soas of the sides 2 to receive a pintle or pin .12, which latter serves to pivotally connect the head to the tail. The tail is 'also'providedwith apair of. spaced depending perforated lugs-13 which receive a straight spring member 14, thememberl i having a driving-fitin the perforations of the lugs,

The front or free end of the member 14 bears against the free edge of the wall 4.- atthe rear of the head, ,soas to exert sufficient tension on saidwall in order to hold the head either in the position depicted in Fig. 1 or that of Fig. 2,;the member 1 1- bearing on the wall. io'nly suf-' ficientlyto effectively hold the head in the positions shown, so as to allow the head to, 5

the I threa head.

From the above it will be apparent that the head can be easily stamped from a single piece of sheet metal which involves minimum expense and labor. Further, the entire structure is simple, and involves a'minimum of parts, whichcan be easily and quickly replaced, if damaged or rendered by wear In addition since unfit for further service. the spring and associated parts face downwardly, they are subjected to protection against injury in an obvious manner.

Having thus described my invention, I

claim as new and desire to secure by'Letters Patent 1. In combination with the-thread board rail, a tail member secured to the under face A nut and screw 15 is employed to secure the U-shaped portion of guide in position relative to thego thereof, a pair of spaced perforated ears on a the tail member from, a pair of spaced perforated depending lugs spring member engaged in the perforations projecting forwardly thereon .thetail member, a straight of said lugs, a head formed of sheet metal blank having a front end formed with. a

concave seat, sides, and a rearwall which latter projects beyond the sides and is engaged at its free edge by the front end of the spring member, said sides at their rear ends being perforated and received in the space between theears, a pin passed through theperforations ofthe ears and head sides,

and a thread guide securedto the head and i 65 7 so as to be secured v having the shank thereof engaged in said seat and having a U-shaped rear portion which engages the confronting faces of the sides of the head. 7

2. In combination with a tail member for securement to the thread board rail, a pair of perforated lugs depending from said tail member, a straight spring secured in the perforations of the lugs, a head pivoted to the tail member, an abutment on the rear and formed from a single piece of sheet metal shaped to provide sides, a front end formed with a seat, and an abutment at its rear end formed from a continuation of the body of the metal, a thread guide carried by the head having a part thereof engaged in said seat, and a spring carried by the tail member and engaged with said abutment.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
