.ment so that when the spring is compressed This invention relates to embroidering yand darning attachments 'adapted to be attached to the needles and needle bars of sewing machines, and particularly to those attachments which comprise a resilient coil designed to take the p ace of the ordinary presser foot and to be attached directly to the reciprocating needle bar so that as the needle risesand falls the Wort: is alternately held and completely released, the obfect of ,my invention, 3
eing to so construct tnc spring coil of the attachment that it may have a maximum of compression and extension, that it may be attachablc to the needlir` bar of a machine above the needle clamp, that it may have a relatively large bearing on the Work, and that it maybe held concentric to the needle under all conditions. rfhese objects l attain by the device shown in the accompanying drawings, wherein-- Figure 1 is a'perspective view of a portion of a sewing machine head, the ordinary presser foot being removed andpmy attachment in position on the needle bar. Fig. 2 is an enlarged ierspective of the attachment detached. il, is an under side vie'w 'of the attachment.
1 designates a sewing machine head of any ordinary 'form or malte and havingthe usual needle bar 2 carrying at its lower end the usual .needle clamp 3 having a clamping screw Ll by which the clamp 'is contracted to securely hold the needle 'to the bar.
5 designates the usual resser bar from which the ordinary presser 'oot has been removed unnecessary for the class of work to be done by this attachment.
My attachment is made of a continuous length of spring wire 6 in tinI form of an clon gated helical spring coil 7, the helix gradually Widening toward the lower end of 'thc attachone turn of the wire will approximately fit inside of the next and larger turn.` The end of the Wire forming the last or lowest coil or turn is inwardly bent to form an eye S which while is concentric with the series of coils.
this eye might be a mere loop of wire, 1 prefer to close the loop and hold it in shape by inserting therein an eyelet 8 which is compressed on the loop. At its upper -end the wire after having formed the smallest coil of the series which is adapted to immediately surround the butt of the needle,'is bent to one side of the center of the coils and then eXJ tended upward parallel to the axis of the coils as at 9, it is then bent laterally and formed into a loop `10. After forming the loop the wire is bent around three sides of an,
approximately square figure as at 11, the end of the Wire being coiled'u ,on itself to form the final loop 12. The o jects of the loops 10 and 12 are simply to provide the clamping portion of the device with rounded corners vv dle bar when the attachment is being placed thereon. l't will be seen that the clamp portion is open at one side and that the needle bar is adapted to be inserted through this open side, and the 'clamp will by its own resilience engage with said bar to hold the attachment 1n place, while the attachment cannot move latcrall because its lower end is held by the need e passing through the'.
In applying the attachment the needle 13 is inserted. through'the uppermost coil and then the clamp is creed into engagement with the needle bar in the manner before stated, the device then assuming the position shown in Fig. 1, 'Upon a depression of the needle bar the lower end of thecoil is forced downward on the fabric. During the time that the needle is passing downward through the fabric the sprmg coil 7 is compressed. While the needle is being u vrardly dravm throu h the fabric the coil still holds the fabric to the table until after the needle has been withdraim from the fabric, at which period the coil itself is entirely raised from the fabric which latter can then be readily moved into a new position ready for a new insertion of the needle. The entire attachment is formed of a single length of s ring wire, is extremely chea easily a plied) and entirely effective for t e work to lie done. 4
In connection with my attachment I use the fabric stretcher 14 shown in Fig. 1. This consists of a ring kof metal having a groove formed in the circumference. The split ring 15 of resilient wire is adapted to be s'tretchefil tightlr over the lower edge of the. .g rm# :and then be in better condition to he ed en. u ttechinent used in connection with the stretcher 14 is not only adapted for enilaundering', lm? peculiarly Well adapted to derning, es it eliows stitches of any desired length or dier lon to be mede.
