SEWING MACHINE FOR STI'ICHINGY WAISTBHANDS.

Application led March 30, 1920. Serial No. 369,885.

To all whom it may concern.'

l Be it known that I, BENJAMIN V. KERSH- NER, a citizen of the United States, residing at Kansas City, in the county of Jackson, State of Missouri, have invented certain new and' useful Improvements in Sewing Machines for Stitching Waistbands, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in sewing machines, and more particularly to a sewing machine for forming waist bands for trousers.

An object of the invention is to provide a sewing machine with guiding devices constructed and so related to each other and to the stitching mechanism as to guide and direct to the stitching mechanism a facing strip with its edges inturned, a body garment, a stifening strip, a binding for the stiffening strip and a tacking strip.

In the drawings Figure l is a front view of a portion of a sewing machine having my improved guiding devices attached thereto;

Fig. 2 is a view of the same parts from the end of the machine;

Fig. 3 is a plan view of a portion of the work support and guiding devices with the `lining strip guide removed;

Fig. 4 is a transverse sectional View through the guiding'devices on the line 4 4 of Fig. 3;

Fi 5 is a View of the tacking guide and showing its relation to the work support;

Fig. 6 is a transversel `sectional view through the guiding device for the lining strip;

Fig. 7 is a view, showing more or less diagrammaticall the needle and loopers of the stitching mec anism;

Fig. 8 is a sectional View through the parts stitched on the machine.

In carrying out the invention, I have applied my guiding devices t0 a sewin machine having two spaced needles and a ooper cooperatin witheeach needle so as to form two indepen ent lines of stitching. Attached to the overhanging arm of the machine is a guiding device for the lining strip of the waist band, which guiding device inturns both the upper and lower edges of said lining. Beneath this guiding device is a guiding device for the stifening strip, and

ening strip', and directly beneath the guiding device for the stifening strip is a guiding dev ice for a tacking strip. The parts are associated so that one edge of the stiffening strip and one edge of the lining stri will be stitched by one llne of stitching to tiie upper edge of the body fabric, while the other infolded edge of the lining strip, the binding for the stitfening strip, the stiffeningstrip and the tackin strip will be stitchedl together by the ot er line-of stitching.

Referring more in detail to the drawings, the invention is shown as embodied in a sewing machine having a work support 1 and an overhanglng arm 2, in which a needle bar 3' reciprocates, carrying two needles 4 and 5. Cooperating with the needle 4 beneath the work support is a looper 6, and cooperating with the needle 5 is a looper 7. The needles are widely spaced, as shown in the drawings, and each needle and its associated 'looper forms a line of stitching, so that two independent spaced lines of stitching are formed.

Referring briei to Fig. 8, it will be noted that the warst ban construction consists of a lining strip L, whichis infolded, as indicated at Z, and this infolded edge lies against the face of the body fabric, indicated at B. A stifi'ening strip, indicated at S, is placed beneath the bod fabric, and a line of stitching indicated at unites the infolded edge of the lining strip, the body fabric and the edge of the stiffening strip. At the same time that this line of stitching is being formed, a separate line of stitching N is formed, which passes through the other infolded edge of the lining strip, indicated at Z. Extending about the edge of the stitfening strip is a binding, indicated at C, and beneath the binding is a tacking strip T, and this line of stitching N', which passes through the infolded edge of the linlng strip, also passes through the binding C, the stiffening strip, and the tacking strlp T.

The lining strip is led through a lining k24 for a tacking strip.

bracket arm 9 which is pivoted to the overhanging arm of the machine so that it may be raised and lowered to give access to the needles for threading. The lining strip guide 8 is of the usual construction and is so formed as to inturn the edges of the lining strip as indicated at Z and l. The construction of this lining strip guide will be clear from the drawings, and particularly Fig. 6 thereof. which is a cross sectional View through this guide. It will be noted that the guide is formed with recesses 10 and 11, which infold the respective edges l and Z of the linin strip. n

Directly beneath the lining strip guide are guiding devices for the stiffening strip, the binding, the tacking strip and the body fabric. These guiding devices are all mounted upon the bracket arm 11a which is secured to the work support by screws 12 and 13. These screws pass through slots 11i- 14 in the bracket arm and are threaded into .the work support 1 and serve as a means to clamp the bracket arm rigidly to the work support, permitting the same to be adjusted in a direction at right angles to the line of feed.

The stid'ening strip guide is indicated at 15 and is formed with a guiding recess 16 for the stifeninfr strip. rlhe stiffening stri goes through this guiding recess unfolde The guide for the stidening strip is formed integral with the bracket arm 11a. Also formed integral with the bracket arm 11a and the stiflening strip guide is a binding guide 17 vwhich has a guldlng recess 18 eX- tending above and below the guiding recess 16 so as to direct a binding strip about the edge of the stiffening strip. The guide for the stifening strip is extended laterally, as indicated at 19, and mounted on this lateral extension is an edge guide 20 for the body fabric. Said edge guide 20 is formed with a slot 21 through which screws 22-22 pass, and which serve as ameans for permitting an adjustment of the guide in a direction at right angles to the line of feed. The guide member for the stifl'ening strip is formed with a slot 23 through which an implement may be inserted for facilitating the insertion of the stiftening strip in the guide.

Below the stiffening strip guide is a guide I This guide 24 is formed with a flat tubular extension for directing thek tacking strip without folding either edge thereof. The guide 24C is carried by a depending arm :'25 which in turn is carried by a shank 26 having slots 27--27 for screws 284-28, so that this tacking strip guide may be adjusted in a direction at right vangles to the line of feed. The work support is recessed. as indicated at 29, so that this tacking guide may be placed below the guiding device for the stifening strip, which is mounted directly on the work support, and

recano@ extend to a point so as to direct the tacking strip underneath the presser foot of the machine, indicated at 30 in the drawings'.

In the operation of the machine, the lining stri L is directed through the lining strip gui e 8, the edges Z and Z the body fabrlc B is guided by the edge guide 20, and this edge guide is so positioned as to direct the body fabric t0 the needle 4. A stili'ening' strip b. is directed to the stiftening strip guiding recess 16, and this is so disposed that the line of `stitching N formed by the needle et and coopera-ting looper 6 passes through the infolded edge of the lining strip, the body fabric and the edge of the stiflening strip. At the same time, a binding strip C is led through the binding guide 17,' and folded about the edge of the stiifening strip.

are inturned, and

A tacking strip T is led through the tacklng guide 24, and this tacking guide and binding guide are so disposed that the line of stitching N formed by the needle 5 and cooperating looper 7 passes through the infolded edge of the lining strip, through the binding strip, the stifening strip and the tacking strip. Thus it is that the waist band parts are practically all completed in one operation. A belt loop may be and guided along with the same and stitched between the lining strip and the body fabric by the line of stitching N.

It is ,obvious that minor chan es in the details of construction may be ma e without departing from the spirit of the invention Tas set forth in the appended claims.

Having thus 'described the invention, what li claim as new and ,desire to secure by Letters-Patent, is
