SEWING MACHINE ATTACHMENT Filed Feb. 4, 1926 //v l/E V TOR ATTORNEY Patented Feb. 9, 1932 UNITED STATES ARTHUR SHUTZER, F BOSTON, MASSACHUSETTS SEWING MACHINE ATTACHMENT Application filed February 4, 1926.

This invention relates to sewing machine attachments for performing certain operations in the manufacture of sheepskin lined coats, and also to sheepskin lined coats constructcd in accordance with the present invention.

Sheepskin lined coats are extensively worn, and as commonly constructed the back and side portions of the coat are lined with sheep l0 skin while the overlapping front portions are lined with woven fabric. The sheepskin lining in most of these coats does not extend downwardly below the waist line of the wearer and a fabric lining is usually secured to the sheepskin lining and extends dowl'iwardly some distance below the sheepskin lining.

This lower fabric lining or bottom lining may be subjected to more or less of a strain incident to Wearing the garment, and it is therefore important that the bottom lining be strongly secured to the lower portion of the sheepskin lining. Furthermore it is desirable that the lower edge of the sheepskin lining be covered to give the same a smooth rounded edge. I

An important feature of the present invention therefore resides in a sheepskin lined coat having a strip of tape folded over the low-er edge oi. the sheepskin and having the upper edge of the bottom lining ioldcd under and secured to the lower portion oil. the sheepskin by stitches extending thru the sheepskin, tape and folded lining.

llhe strip of tape folded over the lower edge of the sheepskin, not only gives the same a smooth and well rounded edge, but materially increases the strength of the seam secur ing the lower lining to the sheepskin, since the folded tape affords a firm surface against which the securing stitches may be tightly drawn and in this manner the stitches are prevented from cutting into the skin face of the sheepskin lining.

.ikuother important feature of the invention resides in attachments for a sewing machine that serve to guide the marginal edge portion of the sheepskin lining to the sewing machine needle, to fold a strip of tape over the edge of the sheepskin, and to fold the edge of the bottom lining under and guide it to the neo- Serial No. 85,888.

dle, so that the tape and folded portion of the bottom lining are sewed to the sheepskin in a single operation.

A portion of the sheepskin coat that is constructed in accordance with the present in vention, and one good practical form of at tachment for carrying out the invention Will be hereinafter described in connection with the accompanying drawings, wherein l is a perspective view of a sewing ma chine n'ovided with the attachments of the present invention, the sheepskin lining and bottom lining being shown in dotted lines;

Fig. 5 is a perspective view showing the parts of the sheepskin coat secured together in accord ance with the present invention.

The sewing machine attachments employed in carrying out the present invention may be ap1 )lied to practically any well known type of sewing machine that is strong enough to sew the heavy material of a sheepskin coat, and in the drawings 10 designates the bed plate of any preferred or vcll. known type of sewin g machine. The sewing machine may have the usual presscr foot 1.]. and may be pro vided with a single needle or with a pair of ncedlcajs desired, the machine illustrated being provided with the pair of needles 12.

The sheepskin lining 1.3 is fed to the sewing machine needle with the wool. face up and a guide 14, which may be adjustably secured to the bed plate 1.0 by screws 15, is positioned to engage an edge of the sheepskin lining and to guide a marginal portion of this lining to the sewing machine needles.

As abovestated, a strip of tape is folded over the edge of the sheepskin lining to which it is secured, and the means for "folding this tape and placing it over the edge of the sheep skin will now he described. The tape 16 may provide a guard be drawn from any suitable source of sup ly, not shown, and passes around the bridge ar 17 which serves as a guide for the tape and is conveniently provided with a laterally extending foot portion 18 which may be secured to the bed plate of a sewing machine by the screw 19. A second bridge bar 20, which may be similar in construction to the bridge bar 17 is secured to the bed plate of the sewbridge bar by the screw 21. It is desirable to for protecting the tape 16 as it passes the guides 17 and 20, and to this end a strip of metal 22, which preferably is bowed in cross section, is secured to the guides so that the tape may pass between the guides and the bowed portion of the guard 22, as will be apparent from Fig. 1.

-The tape 16 passes from the guide means just described to the folder 23 which folder may be constructed of sheet metal to form a tube which is are or crescent shape in cross section to cause the braid to pass between the spaced curved walls of the tube so that it will be partially folded by the configuration of the tube. The folder 23 is preferably provided witha laterally extending base 24 which may be secured to the base plate 10 in the desired position of adjustment by the screws 25. The folder 23 is tapered in the direction of its length so that the fold of the tape will increase as it approaches the end of the guide. This-end of the guide is provided withthe spaced wings 26 adapted to receive the edge of the sheepskin 13 therebetween. The discharge opening 27 of the tapeguide has the U-shaped configuration best shown in Fig. i, and as the tape passes out of this opening it is caused to travel in a direction at right angles to the folder 23 towards the needles 12. By this construction the tape is folded lengthwise as it leaves the guide and is directed by the wings 26 about the edge of the sheepskin 13 as will be apparent from Fig. 4. As the tape issues from the opening 27 of the guide it may be prevented from dragging over the edge of the sheet metal forming the folder 23 by soldering or otherwise securing to the edge of the sheet metal a piece of wire 28 which is bent to conform to the mouth of the opening, as will be apparent from Fig. 4. The" guide 23 is preferably provided with a trough-shaped portion 29 which lies between the wings 26 and extends therefrom towards the needles to. press the folded tape against the edge of the sheepskin 13.

As above pointed out, a sheet of fabric known as the bottom lmmg is commonly secured to the lower portion of the sheepskin lining and it is desirable to fold the upper edge of thislining under to protect its raw edge. A folder 30 is therefore provided for turning a marginal edge of the bottom lining 31 under, and for guiding the same to the mg machine in spaced relation to the first lining 13.- As a'resultof this construction of the folder the marginal edge portion of the sheet 31 is foldedunder as at 35 to provide a smooth, rounded edge 36 which is guided to the sewing machine'needle in overlapping relation'to the oppositely extending edge of the sheepskin 13.

It is desirable that the tape 16- be folded about the edge of the sheepskin 13 so that an upper marginal portion 37 of the tape will:

lie inside of the folded portion 35 of the lining, and to this end-the upper wing 26 of the guide is positioned to extend into the folded 'portionvof the bottom sheet 31 to direct a portion of the tape into this fold, parent from Fig. 4. V

As a result'of the construction described, the guide 14 serves to guide the sheepskin as will be ap- 13 towards the sewing machine needles and as the sheepskin is fed towards the needles the tape 16. is folded about theedge of the sheepskin; at the sametime the uppermarginal edge of the bottomlining 31 is folded under so that: the portion 35 of. this lining liesbetweenthe upper folded portion of the vtape.16 and the wool face of the sheepskin 13. While the-different pieces of material are held in this relation to each other they are advanced to the sewing machine needles and are firmly secured together by one or more rows of stitches 38.. From the foregoing it Will-be understood that the guides serve to guide the several pieces of material to the needle in properfrelation to-each other and that. all the machine attendant need do is to direct the sheet of sheepskin lining 13 towards its guide lawith one hand and direct the sheet of bottom lining towards its guide orfolder 30 with his other hand; as a result of this construction the operation ofsecuring the several pieces of the garment together, as shown in Fig. 5, may be easily and quickly performed. I '1 It willbe understood that thewool face of the sheepskin lining is exposed at the inside of the finished garment, as is also the, folded edge 36 of the bottom lining 31, and since these two sheets of lining are directed to the sewing machine needle in proper relation to each other by the guides described, while at the same time the marginal edge of the sheet 31 is turned under, a smooth, straight seam or stitch .38 will be formed inside of thecoat which gives the samea pleasing appearance. It will also be understood that. since'the. tape 16 is folded about the edge of the sheepskin the stitches 88 do not rest against the skin face of the sheepskin, but rest against the braid, which prevents them from cutting into the relatively soft skin of the sheepskin. As a result the bottom lining is secured to the sheepskin much more securely than in the coats which were constructed heretofore with the threads lying directly against the skin' face of the sheepskin lining.

lVhat is claimed is 1. In combination with a sewing machine, an attachment for guiding portions of a sheepskin lined coat to the needle, comprising a partially closed edge guide mounted upon the bed of the sewing machine so that it opens in a direction to receive an edge of the sheepskin lining and guide the edge portion there of to the needle, a combined guide and folder supported above said edge guide to open in the opposite direction and adapted to receive the marginal portion of a piece of fabric and fold the edge thereof under and guide the folded portion over and into overlapping relation with the needle engaging edge portion of the sheepskin, and a tape folder positioned between the needle and said folder and constructed to fold a strip of tape lengthwise and place it over the edge of the sheepskin in overlapping relation to the folded under por tion of said fabric, that the folded portion of said fabric and the folded tape may be sewed to the sheepskin lining in a single operation by a row of stitches that pass through all of said portions.

2. In combination with a sewing machine, an attaclnnent for guiding portions of a sheepskin lined coat to the needle, comprising in combination, an edge guide mounted in position to engage the right hand edge of a sheepskin lining resting upon the bed of the sewing machine with the wool face up and guide the edge portion thereof to the needle, a combined guide and folder supported above said edge portion and constructed to receive the left hand edge portion of a piece of fabric resting upon the sewing machine bed and adapted to fold said marginal edge portion under and guide the folded portion over and into overlapping relation with the needle engaging edge portion of the sheepskin, and a tape folder positioned between the needle and said folder and constructed to fold a strip of tape lengthwise and place it over the edge of the sheepskin so that its upper edge lies under said piece of fabric, that the folded portion of said fabric and the folded tape may be sewed to the sheepskin lining in a single operation by a row of stitches that pass through all of said portions.
