6 Claims.

This invention relates generally to apparatus for mounting material such as a fabric inner lining upon the inner surface of materials such as leather or the like.

More specifically, my invention contemplates improved means whereby fabric linings may be applied to the inner surface of skins, for example, skins used for fur coats and other similar wearing apparel.

Heretofore it has been common practice in sewing inner linings to skins to employ complicated and expensively constructed special machinery, and it is one of the objects of the present invention to provide apparatus of very simple and inexpensive design, which will greatly expedite the speed and accuracy with which a lining can be applied.

My invention contemplates the use, in combination with elements of a well known, economically constructed sewing machine, of an attachment which renders said conventional sewing machine operable for sewing inner linings to a leather coating or skin.

A further object of the invention is to enable the application of a lining to a fur piece, as above set forth, without subjecting said fur piece to the slightest degree of wrinkling.

Still more specifically, my invention contemplates apparatus whereby the inner and outer pieces of material may be folded so as to present an edge, through which stitches may be passed by a needle without piercing through the outer piece, and at the same time securely fastening the pieces in proper juxtaposition.

The invention contemplates the use of an elongated member or bar having an edge portion, over which the pieces may be folded so as to present an edge at the top of the bar, through which the thread may be passed by a conventional reciprocating needle, rollers serving to clamp the pieces tightly together immediately adjacent the area where the needle enters the piece.

The foregoing and numerous other objects and advantages will be more readily apparent from the following detailed description when consid- .ered in connection with the accompanying drawing, wherein:

Figure 1 is a plan, fragmentary view of a machine which is representative of one embodiment of my invention, and whereby the securing of inner linings to skins and the like may be very eiciently practiced;

Figure 2 is an enlarged perspective view of the bar attachment over which the pieces of material to be joined may be folded, and which serves to support said material as it is fed between the rollers;

Figure 3 is an enlarged, fragmentary plan view of the supporting bar structure and feeding rollers, pieces of material being shown in position upon the bar structure;

Figure 4 is an enlarged transverse sectional view taken substantially along the line dof Figure 3; and

Figure 5 is a fragmentary section of the joined pieces showing the manner in which the stitch is taken to secure said pieces together.

Referring now to the drawing wherein like numerals have been employed to designate similar parts throughout the various gures, it will be noted that my invention contemplates a machine which includes a bed or base Il) (Figure l) upon which is mounted a sewing machine or mechanism designated generally by the numeral I2.

The mechanism I2 may be of any suitable conventional design, and for the purpose of disclosing one practical app-lication of my invention I have shown a mechanism or sewing machine which includes a pair of cooperative material feeding rollers I. These rollers are mechanically coupled with and driven from a suitable drive shaft I6, upon which is mounted a belt driven pulley I8. Peripheral portions of the rollers I4 are adjacently positioned, as clearly shown in Figures l and 3, and by means of serrations or teeth 2i), said rollers are adapted to tightly impinge upon and grip the work, which I have designated generally by the numeral 22 (Figures 3, 4 and 5). Thus, when the rollers I d rotate in the direction indicated by the arrows in Figure 3, the work 22 is moved to the left across the path of a reciprocating needle 2li.

The needle 24 is driven through the agency of mechanism (not shown) which is coupled with the drive shaft i6. Inasmuch as the rollers Iii, needle 24, and the mechanism for actuating said parts are well known in the art, it is not deemed necessary for a clear understanding of the pres-- ent invention, to describe and disclose in detail such well known mechanisms. It will suice to state that when power is applied to the shaft I6, either by a belt 26 or through the manual manipulation of a handle wheel 28, rotation will be imparted to the feeding rollers I ll, and reciprocation will be experienced by the needle 24 mounted upon a suitable shiftable arm S.

Attention is now directed to a bar structure 32, which includes end bar members 3d join-ed by a pair of intermediate side bar members 36, said side bars being secured to the end bars by suitable fastening means or screws 38 (Figure 2). A series of rotary guiding discs 40 are supported within the space presented between the si-de bars or plates 36. The uppermost peripheral portions of the discs All! are substantially coincident with the extension of the upper edges of the [bars 34. The structure 32 is supported in any suitable manner upon the bed l@ as by means of upright members l2 (Figure l).

The bar or rod structure 32 serves as means for supporting the work 22 in proper position to be acted upon by the needle 24. as disclosed in the drawing, comprises a fur section made up of the skin proper 413 and the fur proper 46. a piece of inner lining material d8, such as fabric or the like. The two pieces are folded over the bar structure 32 along the line where it is desired to sew the pieces together. It will be noted in Figure 4 that when the work .22, folded over the bar structure, is fed between the rollers I, the pieces @il and 138 will extend above the upper surfaces of the rollers just sufficiently to permit the needle 2d to pass through the skin M without causing any piercing of the furred surface of said skin. In other words, the needle 2G carries a thread dll through two sections or walls of the inner lining d8 and only through one section or wall of the skin 44.

The Work 22 is initially placed upon the bar structure 32 to the right of the rollers M, as viewed in Figure 1, and is then shifted along the guide discs until the folded margin of the work is firmly gripped and positively advanced by the rollers i5.. The needle 2li reciprocates within the space 52 (Figure 2) presented between the last two discs, toward the left end of the series (see Figures l and 2). The discs 4G reduce frictional resistance and thus facilitate Vthe ease with which the fur and lining material may be shifted along the bar structure. It will be noted that when my improved machine is employed, the pieces may be secured together without the slightest development of surface unevenness or irregularities. In other words, the outer or fur side of the skin 44 is not wrinkled or crimped (see Figure From the foregoing it will be apparent that my invention contemplates the provision of im proved means whereby inner linings and the like may be secured to an outer piece such as av piece of fur. Obviously the invention is not limited to the specific structural features disclosed herein, but is capable of changes and modifications without departing from the spirit and scope of the invention. The drawing shows the work as being fed from the right-hand side of the machine toward the left. In actual practice, however, most machines are right-'handed in which case the work will move from the left-hand side toward the right-hand side. Y
