My present invention relates to attachments for sewing machines and the like, particularly such as are adapted to prevent contact or engagement between the needle or needles on such a sewing machine or the like and the metal of the eyes or like fastening devices which are preferably carried by a supporting tape and are being sewed on to a garment or the like by means of a sewing machine to which the attacl'iment of the pres ent invention has been applied. It is an object of the present invention to devise attachments of the general character specified above which are simple in construction, which may be readily and conveniently fabricated and attached to the sewing machines or the like with which they are intended to be employed,

which are arranged to be operated by such sewing machines or the like, and which in their operation enable garment manufac turers and the like to attach eye or like fastener tape, to garments or the like without danger ofthe needle or needles of the sewing machines or the like being brought into contact with the metal of the eyes or otherfasteners'in such a way as to tend to break or damage the needle or needles or to injure the eyes or other fasteners. It is another object of the present invention to provide mechanisms of the general character specified which will enable garment manufacturers and the like to attach eye and similar fastener tapes to garments without gaps or loose ends, so that by means of the present invention a cleaner and better looking job of the sewing operation may be done in away to add strength to the tapes and to the garments,

fasten the eyes or other fastening elements more safely and more securely in place and to yield a cleaner and better looking garment.

in the accompanying specification I shall describe, and in the annexed drawings show, an illustrative embodiment of the present invention. it is, however, to be clearly understood that my invention is not limited to the specific embodiment thereof herein shown and described for purposes of illustration only.

' Referring to the drawings, wherein I have shown the aforesaid illustrative embodiment of the present invention:

Fig. 1 is a fragmentary side elevation of the arm and associated mechanism of a sewing machine having applied thereto one of the attachmentsof the present invention comprising the aforesaid illustrative embodiment of the same; I

Fig. 2 is a side elevation, on an enlarged scale, of the aforesaid illustrative embodi- 50 ment of the presentinvention attached to the arm or other portion of the frame of the sewmg machme shown 1n Fig. 1 of the drawings;

Fig. Sis an edge View of the mechanism taken along line 8-'8 ofFig. 2 of the drawings; and

Fig. 9 is a fragmentary view, in perspeotive, indicating the manner of operation of the attachment of the present invention.

Before describing the aforesaid illustrative embodiment of the present invention it may be desirable briefly to refer to the state of the prior art to the field of which the present invention belongs. Hitherto, when eye or like fastener tape was to be stitched on to a garment or like article, it was necessary either that the stitching operation avoid the eyes or like fastening devices altogether, as by being passed through a portion of the supporting tape remote from the eyes or like fastening devices, or, if the line of stitching, was preferable, passed across the eyes or equivalent fastening devices, the operator had to take the chance that the needle or needles of the sewing machine by means of which the stitching operation was being conducted would come into contact or engagement with the metal portions of the eyes or equivalent fastening devices and would either become broken or damaged, or would injurethe eyes or other fastening devices and perhaps the tape itself. Accordingly, the

sewing operation, where the line of stitching sible by means of the devices of the present invention; Referring now to theaforesaid illustrative embodiment of thepres'ent invention, and with particular reference to the drawings illustrating the same, indicates an arm or similar portion of the framework of a sewing machine or the like which houses or'contains theneedle operating mechanism andother portions of the mechanism of the sewing machine. Associated with thearm 10 is the head 11 which contains a portion of the mechanism-for causing the vertical reciprocationand the backward and forward movement of the needle holder 12 holding'the needle 13 and with I which is associated the presser foot 14. The parts thus far referred to are of the usual .or ordinary type of construction common in sewing machines of the cordance with the principles ofthe present invention and generally designatedby refcrtypes now employed and need not further be described here. 7 I a Associated with, as by being removably secured adjacent the portion 15 of the arm 10 or head 11 of the sewing machine, whichQis itself generally designated by reference character16, is an attachment constructed in acence character 20. 'In order to properly'support the attachment I provide aisuitable bracket 21 which maybe secured to'theportion '15 of the framework ofthe machine 16 as by the screws 22' The bracket or equivalent supporting member 21 comprises the upper arm or portion 23, the substantially horizontal portion 24 and'the downwardly depending portion 25 having the journal bearing26 at its lower end, in which isrotatably; or oscillatably supported the journal'27 shortly to be described in considerable detail.

The journal 27 comprises the main member 28 having the head 29 slotted at 29' so that it I maybe tightened to adjust it to the. bear- 'ing. The main member 28 is provided with a hole 28 which is threaded as at 28" to receive the threaded shank 30 of the securing member 31 which is slotted at 31 so that it may be operated by a. screw driver or like tool for its adjustment. Positioned between the downwardly extending portion 25 of the supporting arm or bracket 21 and the journal bearing 26, and the slotted head 29 of the main member 28, is a forked member generally designated by reference character 32 and comprising the downwardly extendin supporting portion33 and the forked portion 34 comprising the two spaced arms 34' and 34 morc clearly shown in F igs. 1, 2, 3, .4, 5 and 6 of the drawings."

As more clearly shown in Fig. 1 of the drawings,the forked portion 34 straddles the needle holder 12. Accordingly, as the needle holder moves back and forth, it will cause the oscillation of the forked member 32 about the journal 27 by the engagement of the neodle holder 12 between the arms 34 and 34" of the forked member 32.

The forked member 32 has the extension 35 provided with the flange portions 36 and 3. between which is adj ustably held the arm 38 for a purpose shortly to be described. The arm 38 is slotted, as indicated at 38', so as to permit of its being adjustably retained between the flanges 36 and 37 of the extension 35 by means of a set screw or similar securing device 39, all as more clearly shown in Fig. 2 of the drawings. It will thus be apparent that the arm 38 and the mechanism carriedthereby will be oscillated with the forked member 32 as the latter is oscillated by the engagement of the reciprocating needle holder 12 between the arms 34 and 34" of the forked portion 34 of the member 32.

The member 38 is also slotted, as at 38 so as to provide adjustable means for securing to the member 38 the fastener manipulating. tool or implement generally designated by reference character 40. At its other end the member 38may beprovided' with a pin 41 to which is secured one end of a tension spring 42, the other end of which is secured to the shank of a screw or like member 43 carried by the arm 23 of the bracket member or like supporting means 21. So that the fastener manipulating tool may be rigidly but adjustably secured to the arm 38, I provide a set screw or equivalent securing means 44 passing through theslot 38" and being secured in the arm 45 which carries the manipulating member 46. y

This latter is 'pivotally attached as by means of the screw 47 to the lower portion of the arm 45. The limits of the pivotal movcment of the tool or implement 46 at the screw 47 carried by the arm 45' are determined by means of a set screw or equivalent means 48 more clearly shown in Fig. 2 of the drawings. 49 indicates a leaf spring or the like secured, as at 49, to the arm 45 and bearing at its free end 49 against a pin 46 carried by the manipulating member 46. r

This completes the description of the conlates.

struction of the aforesaid illustrative embodiment of the present invention. The manner of assembling the same and of attaching the A-same to the frame of the sewing machine or the like will, it is believed, be apparent from the foregoing description; Likewise the manner of using, and the mode of eperation of, the attachment will be clear from/the foregoing description but may be briefly sum marized as follows:

Assuming now that the attachment se-- cured in place as illustrated in Fig. 1 of'the drawings and that the machine is started in operation in the usual manner, and that an eye tape 50 is used made up of the folds 51 and 52 of fabric and carrying between said folds the eyes 53, and assuming further that it is desired to sew the eye tape on to the garment, which latter is not here being deemed necessary to be showm the tape will be fed along towards the needle in the usual manner. The action of the tension spring 42 and the leaf spring 49 will be, normally, to keep the point 46 of the tool or like manipulating member 46 in contact with the fabric making up the tape 50 in alignment.

with the loop portions 53' of the eyes 53. Due to the manner of securing the attachment 40 to the sewing machine and the relation of the forked operating member 32 to the reciprocating needle holder 12, when the needle moves forward the tool or implement 46' will move backwards and vice versa.

i ccordin'gly, as the sewing needle 13 descends so as to bring its point 13 adjacent a metal portion of the loop 53 of one of the eyes 53 and the forward movement of the needle commences, the point 46 of the tool or manipulating member 46 will move backwards. The relation of the point 13 of the needle to the point 46 of the tool or manipulating member 46 is such as to cause the tool 46, if brought into contact with a portion of the loop 53 of the eye 53, to move such loop portion a sufficient distance to be cleared by the needle. Y

In the movement of the needle backwards, the tool or manipulating'member l6 will be restored to its initial position and the op eration will be repeated after 'eachstitch taken'by the needle. It will, however, be clear that only a few of the stitches will be taken in proximity to the metal portion, such as the loop 53 of the eye 53. Assuming, for example, that the eyes 53 are made of wire about twenty thousandths of an inch in diameter, the tool or manipulating member 46 should have a range of movement of about twice that or forty thousandths of an inch. This can be arranged easily the proper proportioning of the parts mal ing up the attachments of the present invention, all as will readily be apparent to those skilled in the art to which the present invention re- This completes the description of the mode of operation of the aforesaid illustrative embodiment of the present invention. It will be noted that the attachment comprising the aforesaid illustrative embodiment of the present invention is simple in constructien, may be readily and economically fabricated and assembled and is readily attachable to the sewing machines with which they are intended to be used. In operation it will be noted that the device operates in a simple and expeditious manner for the purposes alreadyset forth. That is, by means of the attachments of the present invention contact or engagement between the needle or needles of the sewing machine and the eyes is avoided with consequent avoidance of danger of breaking or injuring the needles or the fasteners carried'by the tapes which are being stitched to garments or like articles. Due to the fact that the line of stitching which attaches the fastener tape to the garment or like article may pass right through the loopsor other portions of the eyes or other fastener members, a much stronger and neater job is rendered possible, the eyes or equivalent fastener members are more securely attached to the s-up-portin tape and the tape itself more neatly and securely attached to the garment. A cleaner, stronger and better looking garment is thus obtained.

Other superioritios and advantages of the devices of the present invention, particularly as exemplified in the aforesaid illustra ive embodiment of the same, will readily occur to those skilled in the art to which the present invention relates.
