Application May 4, 1953, Serial No. 352,794

3 Claims. (Cl. 112114) My invention relates to improvements in work holders for sewing machines, whereby a closure securing device, such as a hook and eye, may be held in definite space relationship to the stitch forming machine. The stitch forming machine used with the device, hereinafter described, is of the type generally used to secure buttons, hooks, or other fasteners to fabrics or pliable materials.

It is an object of my invention to construct a positioning and retaining device that will securely and definitely position a closure securing device in definite space relationship to the stitch forming machine.

Another object of my invention is to construct a positioning and retaining device that will securely and definitely position a closure securing device in such a way as to require no efiort on the part of the operator, either by hand or hand held tools, during the application of the closure securing device.

Another object of my invention is to construct a positioning and retaining device that will readily position and secure the component members of the closure securing device without requiring any mechanical change to the positioning and securing features of the device.

Another object of my invention is to construct a closure securing and positioning device that will remain relatively free from the accumulation of oil impregnated lint or dirt which would impair the operation of the device or ultimately render the device temporarily inoperative.

Another object of my invention is to construct a closure securing, positioning and retaining holder that can be readily positioned under the needle of the stitch forming machine by the operator.

Another object of my invention is to construct a closure securing and positioning device of the character described which is easily and economically produced, which is sturdy and compact in construction, which provides the maximum protection to the operator, and whose use requires the minimum of effort on the part of the operator.

With the above and related objects in view, my invention consists in details of construction as hereinafter shall be described, the description will be more readily understood when the description is read in conjunction with the accompanying drawings in which:

Fig. 1 is an isometric view of the closure securing, positioning and retaining device embodying my invention.

Fig. 2 is an isometric view of the retaining member of the closure securing, positioning and retaining device.

Fig. 3 is an isometric view of the positioning member of the closure securing, positioning and retaining device.

Fig. 4 is a partial sectional elevational view showing the male portion of a closure securing device in position in the closure securing, positioning and retaining device.

Fig. 5 is a partial sectional elevational view showing the female portion of a closure securing device in position in the closure securing positioning and retaining device.

Fig. 6 is a plan elevational view showing the positioning member of the closure securing, positioning and retaining Patented Apr. 16, 1957 "ice device (securing member not shown) showing the male portion of the closure securing device in position.

Fig. 7 is a plan elevational view showing the positioning member of the closure securing, positioning and retaining device (securing member not shown) showing the female portion of the closure securing device in position.

The closure securing, positioning and retaining device shown on the accompanying drawings is constructed to be secured to standard stitch forming machines. The only portion of said stitch forming machine shown on these drawings is the needle N shown in Fig. 4 and Fig. 5.

Fig. 8 is an isometric view showing a modification of the supporting and positioning members of the closure securing, positioning and retaining holder. This modification provides for lateral and transverse adjustment of the positioning member of the closure securing, positioning and retaining device.

Referring now in greater detail to the drawings, I disclose a closure securing, positioning and retaining device comprising a positioning member A; the positioning member being pierced with hole 1 that are arranged to receive securing means, not shown, so that the device can be securely attached to a standard stitch forming machine.

The outer or work end of the positioning member A has a definitely shaped cavity 2 therein, said cavity having two opposed curved surfaces 3 with inwardly projecting flanges 4 arranged to receive the loop portions 5 and 6, of the male C and female D closure securing devices; said flanges 4 have a circular inner edge 7 arranged so that it is clear of the needle of and the stitches formed by the stitch forming machine.

An eye receiving receptacle 8, part of cavity 2, square in form, is arranged to receive the eye 9 of the female closure securing device D, a hook receiving receptacle 10, an extension of and part of the cavity 2, is arranged to receive the hook 11 of the male closure securing device; said hook receiving receptacle 10 extends completely through the positioning member and serves as a discharge outlet for lint or dirt that may accumulate in the cavity 2.

The features of the cavity 2 in the support and positioning member A, as above described, are arranged for definitely positioning both the male C and female D closure securing devices in the work end of the closure securing positioning and retaining device.

The closure securing devices C and D are held in position in the closure securing positioning and retaining device by the retaining member B; said retaining member is definitely positioned and the positioning member A by the pin 12, which interfits with the hole 19 in the retaining member B, the yoke 13, and the downwardly extending ribs 14 at the work end of the retaining member, said ribs interfitting with the sides 15 of the eye receiving receptacle 8 of the cavity 2 in the positioning member A. A spring 16, retained by the yoke 13 and a positioning screw 17, maintains pressure on the retaining member B.

The Work end of the closure securing retaining member B also has two downwardly extending ribs 14, said ribs interfit with the eye receiving receptacle 8 of the cavity 2 and are of such a length in the downward direction that they engage the eye of the female closure device D when the female closure device is in position in the positioning member A, the retaining member B is forced upward by this engagement of the ribs 14 and the eye 9 of the female closure securing device D, this arrangement provides the tension necessary to retain the closure securing device D in position in the positioning member A.

In Fig. 8 I have illustrated a modification to the support and positioning means of my closure securing positioning and retaining device. In the modification illustrated, the positioning member A1 is arranged to c0opa V 3 1 erat'e with a lateral and transverse adjustment member 21, said positioning *member A1 is rotatably "attached to 'said adjustment member 21 by the bolt 27, transverse adjustment is made possible by movement of thetsecuring bolt 28in the elongated "hole 29 infthe'adjustm'etit member-21. The adjustment member is atteicliedtothe bracket member Z'T bythe bolts 25;h'ow'ever, {lateral movement of the V adjustmentrnember is 'provibledbythe longation'ofithe 4 able detail, such description is intended as illustrative rather than limiting, as the invention may 'be variously embodied and the scope is to be determined as claimed.

I claim as my invention: 1. A closure securing, positioning and retaining device for a sewing machine comprising a horizontally extending V V hook and'eye positioning member which has a cavity in its front end, said cavity defined by two arcuate spaced walls which are adapted .to receive "opposed curved surtion'ing andiretainingholde'r. A cord or'ehainfi'l attached to the positioning member by a securing screw 30 is provided'as a'means for'raising the entire hold'er. Tension is exerted on the cord for raisingandlow'e'ring Lthe hblder by a tootfc'ap'eratecl pedal actuating a -lever (not shown). r
