l REISE'R v CONTROLLED SWEAT BAND GUIDE Filed Oct. 7, 1940 4 lS/DOPE 'RE/JER INVENTOR BYWMM/ ATTORNEY Patented Oct. 27, 1942 I UN ITED ASTATES PATENT yOFEICE- I fgzsaesov CONTROLLED SWEATBAND GUIDE IsidoreB'eiser, New York, NY. Application October 7,1940,SerialNo. 359,995 2 Claim's. (Cl. 1 1215) This invention relates'tosewing machines for sewing sweat bands to hats. I

Inpresent practice it is customary for the operator to turn the-hat inside out beforesewing in thesweat band in order to have'full visibility of the sweat band and to be ableto guide one edge of the'bandlin li'ne with the loweri edge of the crown. l

It has been found insid out deform the shape of: the hat: and leaves permanent damage markswon the hat, unless reblockedl l An object of this inventionis to provide mechanism whereby a sweatvband maybe/stitched to the inner surface of th hat without turning the hat inside out and thus vobviating the resulting damage to the hat and the necessity of reblocking. i l v i v v Another object of this invention is to provide mechanism comprising a self-contained sweat band guiding and cuttingofi andieedingmeans,

whereby the operator may easilysever th .sweat band to its proper length and on the :proper 'bias before completing the sweatrband sewing operation.

With the above'and other objects in view, the invention will be" hereinafter more particularly described, and the combination and arrangement ofparts will be shown in the. accompanying drawing and pointed out in the claims which form partof this specification. l l n Reference Will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout th several views, in which:

Figure 1 is a front elevation of a sewing machine having the sweat band guide mechanism applied thereto.

Figure 2 is a central longitudinal cross-sectional view of the guide mechanism.

Figure 3 is a cross-sectional view, the section being taken as on line 3-3 in Figure 2.

Figure 4 is a cross-sectional view, the section being taken as on line 44 in Figure 2.

In the illustrated embodiment of the invention, the numeral l indicates a sewing machine comprising a fram H, a standard l2, a main shaft l3, an oscillating arm I4 pivoted at l5 and operated by a pitman IS. The lower end of the pitman is in engagement with an eccentric (not shown), on the main shaft 13.

The sewing machine comprises a reciprocating needle bar IT, a needle 18, a presser foot I9 and a bottom feed-dog. These parts operate in a that this turning of the hat mannerwell known in' the" art, asshownin Patent No. 1,085,401. Th sewing machine hasbeen mounted on an off-set pedestal 2|,and the base 22 of the-sewing machine is in overhanging relation with the pedestal. A table 23 has a'vertical extension 24 carrying a pivot 25 on which a roll 26 of strip fabric 21 has been rotatably mounted. I I

Thesweat band guide 30 comprises a hollow rear member 3| having a sideways extending arm '32 which is bolted to a vertical extension 33 0f the sewingmachine base 22 in a manner as to position the lengthwise side of the guide 30 substantially upright. I I i The rear member 3| ofthe guide 30 has its upper end portion 34curved outwardly andcontacting'with the base 22. A lever 35 has been pivotally mounted on e pin 36 in the vertical side walls 31 of the guide 36. A coil spring 38 intermediate thelever 35 and a hollow threading member 39 presses the upper edge of the lever-'35 inpressure contact with th uppermost edge of the guide 30 and serves to support a fabric strip or sweat band for movement under the presser foo'tlS'for feeding'movements by the'sewing machine.

The hollow threading member 39 has been pivotally mounted on a pin-43 in the vertical side walls 3'! of the guide 30 with its upper Walllin pressure contact with a toothed roller 41. The roller 4| has been rotatably mounted on a pin 42 in the vertical side walls 31, of the guide 3|,

Ay-knife 43 carried by the lever 35 is guided by1ugs44 on opposite sides-thereof and in aline ment with an angularly positioned slot in the rear member 3 I.

As shown in Figure 2 the sweat band 21 has been threaded through the guide 30, in a manner which permits the operator to first press down the lever 35 and force the knife 44 into the slot 45 and severe the sweat band in bias form. The operator then rotates the toothed roller 4|. and causes the lower portion of the band to be raised by the roller past the uppermost edge of the guide 3!] and to be moved under the raised forward end of the presser foot for feeding movements by the well known sewing machine feed. It is to be understood that the operator actuates the lever 35 away from contact at the uppermost end portion 34 before actuating the toothed roller.

It will thus be seen that my sweat band guide 30 serves first to frictionally support the sweat band at a point adjacent the feed dog of the sewing machine and prevents overfeeding and wrinkling of the sweat band while it is sewed inside the hat. The guide 30 also serves for severing the sweat band in a definite angular direction, and also serves for raising the cut-off lower portion of the fabric strip into position adjacent the presser foot for repeating the said erations when stitching another sweat band i to another hat. As shown in Figure 1 it will e noted that the roller 4| is positioned within the threading member 39 so as to be adapted to feed the fabric in the same linear direction as the line of feed of the sewing machine.

The sewing machine I0 is of the chain stitch type wherein an article is stitched with only one thread, and wherein the upper surface of the article shows a straight line of stitches while the lower surface of the article shows chain-stitches.

As shown in Figure 1, a hat 46 has been positioned in operating relation conformin'g'to the present invention. The hat 46 has not been turned inside out and when the sweat band has been stitched into the hat the chainstitches show only on the inner surface of the hat. The outer surface shows straight line stitches. This arrangement of the stitching is very desirable because exposed chain stitching necessitates' the addition of a ribbon to cover the unsightly chain stitching.

It will thus be noted that the prior practice of turning the hats inside out prior to stitching the sweat bands is hereby obviated. With the method of operation herein disclosed it is not necessary to turn the hats inside out and there is no necessity for reblocking a hat after stitching th sweat band therein.

I have provided a bolt 41 and nut 48 for tensioning the supply roll 26. This tensioning makes it possible to control the length of the sweat band material being fed to thehat during the stitching operation. I can thus decrease the'length of the sweat band fed to the respective hats and thereby vary the hat size of the hats as desired.

In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.

I claim:
