To all whom it concern,

- .Belit knownthat I, JOHN HAeE ,a citi- Zenofthe UnitedIStates, residing at St. Louis, in the city of St. Louis, State of Missouri, have invented certain new and useful. Improvements in Adjustable Guides for Staying Machines, of which the following is a description, reference being had to. the accompanying drawing andto the figures of reference marked thereon. i :Tl1e invention relates to new and useful improvements in tape guides and more particularly to tape guides which are as: sociated with an attachment for cutting and directingfa stay strip to a stitching mech: anism.

' It has "been a common expedient in the sewing machine art tofeedbyf means of a manually controlled feed finger, a staystrip. to the stitching mechanism and to out said stay strip by said manually controlled means. The cutting is brought aboutby a reciprocating cutter which moves across the path of the stay strip and severe the; same. Considerable difficulty has been experienced in properly guiding the end of thestay j strip afterit, has been cut, to gthe presser foot fortl e. nextstaying operations 7 An object-of the: present invention is to provide guiding devices for the stay strip which are located between the cutting mech anism and the needles of the; stitching mechanism, so as to controlthe stay strip until it is receivedunderthe presser footand also t' guide said stayhstrip during the Sti ch ng thereof; I

TA furthelif bjedt of. is to provide guidesof the above" character, which guides are adjustable and which are I. readily accessible for adjustment, and which are also visibleto theoperator, so that it may beeasily seen whether the stay strip is being properly directed to the stitching mechanism.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings which show by way of illustration one embodiment of the invention- Figure 1 is a plan view of.a part of a sewing machine having my improved guidin devices applied thereto;

Figure 2 is a front View of the same.

i919. sash 110,525,4 I In the patent granted to Benjamin. Kershner January 18,; 1916,1No. 1,169,088, there is shown and described a stay cutting attachment for sewing machinesfwherein the stay strip isfed forward beneath the presserfoot'by a. manually controlled finger. The inean's whichicontrols this feeding fin geralso' operates a cutter. Whenthe lever is depressed which controls. theffinger and cutterfthe cutter is raised to: sever the stay strip N Yh en weaver: is raised thenthe feed finger moves the; tape forwardfto the front end ofthelpre sserfoot and intoen gagement withthe feed. invention is I adapted totbe used in connectionwith an attachment of the fcliaracter described in said patentflfi, I I 1 Theimproved, means for thestay strip devised by meronsists of guiding devices located between the cutter andthe, Stitching mechanism,which guiding devices are open to viewby the operator, so -that it can be readily determined, whether the stay strip I is being. properly guided, ,Theselggu iding devices also insure thatthe stay; strip .;when fed a forward by I the feeding! finger shall be guided' so: thatjthe stay strip will .be properly Centeredv relative (to, l the needles.

Said guiding. devices I are also adjustable, so I as to shift the position of the; stay strip or aewm clatastay st p p e en wi h and also center thewstrips. I

fReferring more-in detail to theldrawings,

I have shown my improved guiding device applied to. stay cutting attachment; which includes a reciprocating cutting blade, 1, cooperating witli a stationary. cutting blade 2i Theattachinentis mounted on the work support'ofthe sewingmachine, ,whichis indicat aerate in the drawings. ,The feeding mechanisrnfincludes a feed dog white; is indicated at 4 in the drawings and a stitching mecha nism having two needles indicated at 5 and 6,

respectively, in the drawings. The stay strip is fed forward by a feeding finger which is mounted on an arm 7 carried by a shaft 8. Said arm is oscillated by means of a lever 9 which is manually controlled by a spring 10 which moves the lever when released by the operator. The cutter is controlled by this lever 9. These parts of the stay cutting attachment are all similar to those shown and described in the Kershner patent, and have only been illustrated more or less member 11, is carried by an arm 13 which 7.

rests on the upper face of the Work support. The cover plate 30 f thestaying attach ment proper is formed with a recess 14 and said arm 13 has a projecting member 15 which lies in said recess. Said projecting niemb'er'is formed With an'open ended slot IGJ'and a setscrew 17 passing through the may be moved so as to adjust the" edge guide 11in a direction at right angles to the line of {feed a or h path of travel of the stay strip. The edge guide 12 is carried by an arm '18 which als'o has a proje ting member l 'extendin'g into a recess 20 in the cover plate of the stay cuttingattachment and said projecting member is formed with an 'openlendedslot 21 similartothe slot 16;, in which is placed a screw 22. By loosening this. screw'the" edge guideIQ may be adjusted in a direction at right angles to the'line of feed or the path of travel of the stay stripi flhe stay "strip is ind cated at'S 1n the drawingskf Said-stay strip passes'through the eutting attachment across the path of movenrent of the cutting blade: 15 which is manually controlled by the leverfl. When. said buttin blade 'is raised" the "stay strip will be sewed;- This is aeconiplished by depressirig the-lever 9. When the'lever 9 is raised through the action ofthe spring 10, the feed fin er moves the stay stripiorwardly to a pointjclosefto-the' needl s 5 and .6, The edge 'gi1ides ilfand 12'' are located between thereci roeating cutting blade 1 for sever:

ing thestay stri and the, needles 5 and '6';

so that when this entfedge isproject'ed for wardl'yfihythe feeding finger,'these edge guides will control and direct the stay strip until it reache's' oint underneath th presserfif o t of e sewing machine. Furthermore, the edge guides will control the stay strip at all times as it passes from the cutting attaehment, to 1 the needles;

\ Theseiedgeguides are visible to the operator, smthat it maybe readily seen whether the be adjusted toward and from each other to aceonimodate different Widths of stay strips. *iW'h-ileil have 'des'eribed the invention as particularly adapted for a stay strip pass,- ing through ajstay cutting attachmentyi't Willbe obvious that-from certain aspects of the invention, it maybe used for otherflpnr poses in connection with; the guiding iof 'Ia'vjing thus described my invention, what I claim as new and desire to secure Letters Patent is: i 1
