Be it known that LHARLEY O. MoUL'roN, a citizen of the United States, and a resident of Maplewood, county of St. Louis, tate of Missouri, have invented an Improvement in Blindstitch-Sewing Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. I

This invention relates to improvements in blind stitchsewing machines for sewing the edge portion. of a superimposed layer upon a base layer of material by a series of blind stitches in both the base and superimposed layers and the general object thereof is to provide means for insuring accuracy and uniformity of the stitches in the superimposed layer.

Av further object of the invention is to provide a mechanism which will enable uniformity of stitching in a superimposed layer of very fine or sheer material.

A further object of the invention is t0 i provide adjustable means for guiding the edge of the superimposed layer which will enable the production of uniform and accurate stitches in the superimposed layer and .also enable such adjustment to be made as may be necessary or desirable to accoinmodate goodsvof different thicknesses, quality or character.

More particularly the invention relates to improvements in blind stitch sewingmachines for felling a superimposed layer of material upon a base layer comprising aneedle reciproca-ble in the general direction of the line of feedwith guiding means, preferably carried by the presser foot, for directling the upturned edge portion of the superimposed layer into the path of the needle, with 'a gauge also preferably carried by the presser foot located in proximity to the needie path and preferably embracing the edge 'Y of the superimposed layerat-the stitching point and yieldable to thepassageof the needle and the material of thesuperimposed layer which is caught bythe needle upon its penetrating stroke. f v

A further object of the invention is to provide-an improved presser foot for blind stitch sewing machines comprising a body to and a major toe portion with a minor toe portion lrigidly mounted upon the 4presser foot which is adjustable .transversely relaprovided Withan adjustable guide vand also desirably with an adjustable gauge for the purposes above set'forth.

Other objects and featuresof theinven'tiofi will more fully appear from thegfollowing description and thev accompanying drawings and ,willbe particularly pointed outfin, the claims.

A preferredv embodiment invention is disclosed herein as applied tothety'pe, of blind stitch sewing machinespfoif'vsewing a superimposed layer upon a baseljlayerofmaterial which is illustrated and describedin my prior Patents Numbers y1,469,675 Aand 1,469,676 granted October 2, 1923'. The machine referred to comprisesa bed plate, a standard rising therefrom providedwith an arm overhanging said bed-plate having a head carrying a curved-oscillating and. laterally vibrating needle and complemental stitch forming mechanism and,A an. upper feeding mechanism actuated .by the Amove,- inent of the take-up mechanism. 'lhelwork is clamped between a presser foot'c'arriedby a hook bracket depending from the head and a relatively movable work support which is normally held in clamping relationlto the presser foot, but isl separated the-refro'mto release and advance the woikfby the action of the feedingmechanism.- Inthat machine a suitable bender is reciprocably mounted-l in the work support and is intermittently `actuated to presentthe upperislurfaceofthe base layer'in the path of the needle during its movement in one plane, while the edge portion yof the. superimposed l layer;is f en gaged by the needle upon itsfieciprocation in another plane, both ofsaid planes of reciprocation of the needle being in the direction of the line of yfeed ,and preferablysubstaiitially parallel to the line offeed." .Y

The feed 'bar andl'dogs 'are given their. reciprocating feeding movement 'through al lever '15'= 'which isy pivotal? 1y connected' at its lower end to the feed har 12 and fis actuated from'tbe take-up, andthe feed bar and dogs are lgiven a vertical movement through an arm 16 rigidly secured to the rear end of the feed bar 12 and operated from the needle actuating mechanism, all of which 'mechanisms :are fully c lislo'sed'- in the patents aforesaid.

The feed dog is then given a longitudinal rearward movemern` 'Which'advanc'es the Work a dist-ance of ont stitch. The feed bar is then yoscillated upwardly permitting the spring 10 to yforce` fthe work support again into clamping rela- .tionto the'presserfoot and the dog is ther advanced into position `to again `grasp anc feedthe Work for another stitch.

A {[nrnachines of this type guiding mean: areprovided for presenting the edge of th: superimposed layer into the path of thl 'needle "during the oscillationof the needh in one patlnavhile. the. lower bender 11 if actuated to present4 the base layer into 'tlm A path tof 'the' needle during the oscillatioi lo'fthe needle in the other path. i

The .presentv'invention relates to mean for guiding theedge of the superimpose( ilayer 'into one of the ,paths of the Aoscillat 'ing vibrating needle andv in its broad aspec Ycomprises a resilient gauge, preferably'o a form to embrace the upturned edge por tion of tliesuperimposed layer7 Iand lo cated in such proximity to the needle pat that it is yieldable to the passage ot th needle and the material of the superim vposed' .layer which is caught by the needl during. 'its penetrating stroke. Such gauge may besupported in an)7 suitabl manner, but preferablyv is mounted upon th minor toe of the presser' foot andv is ad instable transversely relatively to the needl path.v The guide ma)v be so adjusted tha when a centre-pointed needle is employe Vthe point of the needle will pass 'throng the gauge, but the resilient gauge will yiel to f tliegpassage'of the body 'of the need] 'andfthe material of the superimposed laye fwhichijscaught by the needle and intel vposed between it .and the resilient guide.

' By reason of this construction ver5v a( curate and uniform penetration ofthe need? intdtliesuperimposed Alayer is attained an 'alsov means provided lfor accuratel)T and un formly Ystitching very tine sheer materi: A when used as a superimposed laver upon tll base layen The minor toe of the press ffo'ogt desirably lis also adjustably moun edlrigidly upon "thevvv presser foot 'in ord( `that it may be properly positioned to a with -the greatest advantage upon materia of d iferent thicknesses andof different che` lacter.

The adjustable presser foot desirably also provided With an adjustable and dA tachable guide for directing the superin posed laver towardv the stitching point, tlA detachability of the guide permitting sul stitution of suchl guidelv as may be suitable for the workwhich is operated upon.

Inithe preferredembodiment ofthe invent-ion illustrated in the accompanying drawings the presser foot 6- is provided with a pair of ears 17 and' 18 which are secured respectively by

suitable screws

19 and 20 to the hook-bracket 5, the'heel of the presser foot extending beneath the hook bracket as illustrated in Fig. 1. The presser foot comprises a forwardly extending toe 21 which pro-jects from the outside of the presser foot and the under side ofthe toe 21 is provided with a channel 22 (see Fig. 4) forming a guideway for one feed dog. A shoe 23.7ex* tending rearwardly from the presser foot, engages the outer side of the other feed dog and acts in conjunction with the under Jface 24 of the heel of the presser foot and with the wall of the guideway 22 to strip the goods from the ieed dog when they are raised before being advance-d to work engaging position.

The usual needle plate 25, which is securedv te or formed'integral with the under 'side of the presser foot, extends laterally across the line of stitching and has a curved upper surface 26 extending to the needle 'throat 27 and corresponding to the are` of reciprocation of the needle. rlhe heel portion oi" the presser foot has a curved surface 28 also corresponding substantially to the curvature of the needle which serves to support the needle after its passage through the work and thereby p-revent its deflection. The inner edge of the needle plate is provided with an upwardly extending flange 29 which serves as a. guide for the side of the needle in the stroke in which it penetrates the superiumosed layer as is usual in blind stitch sewing machines of this type. A member 3() is secured to the upper face of the toe oft the presser foot and is provided with an upwardly extending arcuate guiding i'lauge 31 which merges into the plane of the inner edge ot the guide 29 and forms :in abutment against which the operato!` 'may guide the edge of the superimposed layer and cause the same to be turned upwardly as it approaches thestitching point.

The edge ot the superimposed layer which is thus turned up is engaged by the guide and byy the guiding audgauging means comfprising the embodiment of the present invention which direct the edge of said superimposed layer into the path Iof the needle as heretofore described.

lIn the preferred embodiment lof the inventioul disclosed herein the guide and vgauge are mounted upon t-he minor toe of the presser foot.. In the present .embodiiuentof the invention the minor toe ofthe 'presser 'foot is adjustably mounted upon a `toe-supporting member which issecured to one of the .ears of .the presserfoot, As

illustrated the toe-supporting member is in: the tormI of a substantially rectangular' block 32 which is secured to theV ear ofthe presser foot and to the'hook ybracket by the screw 19. It has a laterally projecting arm 33 provided with la rearwardly offset end portion having a slot 34 whichfis engaged by adog 35pivotallysecuredbyascrew 36 to the top of the body of the presser foot. rI'his dog so positioned as to lock. the presser foot supporting member in such pos-ition that the Work engaging face of the presser foot will be properly'located with respect to the surface of the superimposed layer.

The minor toe of the presser foot is inthe form of a shoe 37 having anupwardly curved front end 38 and a convexedly curved rearwardly' extending surfacel B9 com'erging toward the line of: stitching. T he shoe has a laterally extending arm40 provided with slots 41 which receive screws 42 which are seated in the presser foot supporting member or bloclr32. Byreason of this connection the minor toe ofthepresser toot may be adjusted towardand from the line of stitching. Ther curved converging under face of the presser foot engages the upper surface. of' the edge portion of .the

superimposed layer and acts to crowd the upturned edge of the superimposed layer toward the stitching point. f

'A guide 43, for the edge of the superimposed layer, is provided, this guide preferably being in the form of a plate having a doivnwardly curved endl portion 44 which embraces the edge portion'of the superimposed layer with the flat portion-'of the guide resting upon the top of the edge of the layer thereby limiting the height to which the edge is turned upwardly. The curved end portion 44 ot the guide serves to guide. the edge of the superimposed layer toward the path of the needle. 1 I

The guide plate 43A is provided withr a slot to receive a clamping screw 45by means of which itis adjuster-bly secured to the minor toe of the presser foot and is adapted to be adjusted relatively'to said minorv'toe and to the' needleA path. The other lend 4b of the guide 43 desirahly is of a reduced width and extends into a slot in the laterally extending arm 40 of the minor toe.

This guide can be detached by remov- 'ing the screw45 and other guides substituted ltherefor according to the character of the material of' which the superimposed layer is formed7 or for producing Wider stitches in the superimposed layer, that is to say stitches which lare located at a greater distance from the edge of the superimposed layer.v An illustrative substitute guide-47, adapted'to produce a wider seam of this character, is illustrated in Fig. 8.

This guide obviously may alone be used to the gauge -toward direct the edge of the superimposed layer into the path of the needle and the adjustabi-lity of this guide together with the adjustability of lthe minor toe of the presser toot, which serves to crowd the edge of the superimposed layer toward the needle path, provides means for properly guiding various different thicknesses and characters of the material of the superimposed layer into thepath of the needle. y

Vhile the presser' feet of blind stitch sewing machines have heretofore been provided with guides somewhat similarly located, so far as I am aware no presser foot has heretofore been provided with a minor toe portion which is adjustable toward and from the .line ot' stitching, or with an adjustable and detachable .guide mounted upon an adjustable minor toe po-rtion of the presser foot. rlhe present construction enables a lgreater variety ot superimposed layer material to be properly presented to the stitch forming mechanism than in other constructions heretofore produced.

ln addition to the novel guiding means for the superimposed layer the present invention .comprehends the additional means for insuring runiformity and accuracy of stitching in the superimposed layer above generally described.

In the particular embodiment of the invention herein this mechanism is in the form of a gauge comprising a resilient plate 48 'ot general L-shape form having a shank 4:9 provided with a slot 50 which receives a clamping screw 51 which is seated in the under surface of the presser foot supporting block 32 (see Fig. 'l). The gauge is provided with a central upwardly curved portion 52 which increases its resilience and a downwardly curved end portion 53 positioned to embrace the edge of the superimposed layer at the stitching point. The end portion of the gauge 49 desirably lies in such close proximity to the needle path that the point of a centrally pointed needle may pass through the gauge adjacent its downwardly curved end, but the resilient gauge will be raised by the body portion ot the needle and the 'material which is caught by the needle during its penetrating Stroke.

By Areason ot' this construction exceeding accuracy and uniformity of penetration ot the needle in the superimposed layer and the length of the stitch therein is attained and skipping of stitches by the needle is obviously avoided.

The gauge may be adjusted for dierent thicknesses or character of material by loosening the screw 51 and sliding the shank of or from the path of the axis of the needle as may be required.

n order to insure accuracy of the penetration. of the needle in the base layer an abutment is Iprovided for limiting the upward movement of the bender 11 in such a manner that a predetermined depth of stitching will be made in the base la-yer irrespective of the goods of rsaid base layer. As 'illustrated herein a stop or abutment is provided which is of L-shaped form,the vertical arm 54e having a tlat under surface to engage the base layerimmediately -above the axis of the benderlfwhilethe laterally extending arm 55 is provided `with an enlarged end 56 which is pivotally mounted upon the screw 20 by which the ear 18 of the presser foot is secured to the hookbracket 5. An adjusting screw 57 having a slotted top passes through thearm 55 of the L-shaped stop member and is seated in the major toe portion 2l ot the presser toot. -A'suitable spring acts normallygto raise the, abutmentor stop 5a. As illustrated'herein the spring is of L-shaped form comprising a hor-iZontalportion-S having a down-turned end which rests upon the top ot the major toe portion of the presser foot and a verticalportionv 59 which is secured by a screw .60 tothe horizontal arm 55 of the abutment member. The vertical portion 59 of the spring is provided with laterally extending wings l'which engage the knurled periphery of the adjusting screw 57. The spring 58, therefore, holds the arm 55 of the abutment pressed upwardly against the under tace of the set screw and by adjusting the setscrew the position of the lower end Aof the stop or abutment can be accurately positioned to limit the upward movement of the lower bender.

l lt will be understood that the embodiment of the. invention disclosed herein is illustrative in character land is not restrictivo and that various modifications in form, construction and arrangement of parts may be lmade within the scope of the invention.

It will also be understood that the invention .may be applied to other types ot presser foot-'0r embodied in other blind stitch sewing machine constructions within the spirit and scope of the following claims.

Having .thus described the invention, what isclaimed as new, and desired to be secured by :Letters Patent, is:
