STITCHING MACHINE.

v Application tiled (Zlotoberl 9, 1926. Serial No. 140,623.

tern are cut from a pile of several layers ofv cloth. f

In the manufacture of garments in; quantity production, it is Customary to lay upona table a pile of cloth consisting of several layers and marking upon the topmost layer the outline of the pattern to be cut and then cutting through tlie entire pile andsimultaneously producing a multiplicity of like pieces by using an kelectric or othery motor-driven cutting'machine that is manipula-ted by the operator to follow the lines of the pattern as marked on the topmost layer as above stated.

In order tov niark the several pieces forthe location of buttons, buttonholes and pockets, and for other indications',y itis quite a common practice to stitchk through the pile of'cloth at the respective places to be Vmarked ywith a relativelyy long piece of rthread and leaving it either in a. single strand or looped double through the entire pile of cloth, and then,

after the respective places have been so of Figure 5; ,Y

Figure 9 is a top plan view of the presserstitched, the several layers ofthe clothfare separated and a portion ofthe strand or loop of thread is severed on either side of the respective layers, so that each layer has a fragm entV of the thread therethrough and extending on each side thereof. which fragments are easily pulled out when no` longer required. l f

The present invention has for its principal object to produce a simple, practical and eilicient machine for stitching the clothv for the above noted purpose; to secure precision and positive action with ease of operation of the machine; to provide for the ready release of the loop catching device of the machinel Without necessitating a manual operation of anv associated actuating *element of saidV device; and to attain vcertain advantages as will more fullv'appear in the following description.

'The invention consists in the novel construction and arrangement of the machine as a Whole and the parts and combinations and arrangements of parts thereof. all as herein after described and afterwards pointed out with particularity in the appended claims.

Figure 19 is a similar view, the parts being shown in operated position.

Referring now to the drawings, the numeral 1 designates the base-plate of the machine, which is made hollow and is open on its under side, and being stiil'ened by longitudinal and

transverse ribs

2, 3, respectively, as more clearly shown in Figure 3 of the drawings.

Secured on the base-plate 1, as by screws 4, preferably inserted from the bottom` as shown more clearly in Figure 3, is a standard 5 extending upwardly from the rear end portion of said base-plate and having a forwardly extending, substantially horizontal arm 6. At the forward end of said arm 6 is a head portion 7 having fiat top and bottom faces and rounded end portion 8 (see Figure 8 of the drawings), said head portion 7 having a bore 9 therethrough (see Figures 5 and 8).

Secured, as by screws 10, to the under side of said head portion 7,` is a plate 11 having a cylindrical upward extension 12 located axially in said bore 9 and being of considerably smaller diameter t-han said bore; and lit-ted tightly over said cylindrical extension 12 is a tubular member 13 which extends some distance above the head portion 7 and serves a guide for a second tubular member `14 that is sleeved on said member 13 so as 'to slide freely thereon, there being an annular .space between the lower end portion of said tube 13 and the wall of the bore 9 of suiiicient dimensions to receive the lower end portion of said tube 14 when the latter is moved to its lowermost position during its operation as will be later described.

It is to be here understood, of course, that said tubular member 13 is fastened securely to `said cylindrical extension 12 of the plate 11 by pinning, welding, or other approved or practical methods, and by the same process a. bushing 15 is secured within the upper end portion of said tubular member 14. This bushing 15 is internally screw-threaded for the reception of a screw-threaded plug 16, preferably having a lnurled, annular, outer collar portion 17 Vfor convenience in placing said plug in and removing it from said bushing 15. This structure is best shown in Figure 5.

Secured axially in said plug 16 is a needlecarrier comprising a bar 18 in whose lower end portion is secured a needle 19. Normally, in the uppermost position of said bar 18, the lower end portion of the bar is supported and guided by a bushing 20 that is secured within the upper portion of said tubular 13. 1When said bar 18 is lowered, its

lower end portion passes through a second bushing 21 located approximately midway between said bushing 2O and said cylindrical extension 12 of the plate 11, which latter is provided with an axial bore 22 of the same diameter as the bores of said

bushings

29 and 21, all being such that said bar 18 will slide readily through them. l

In the raised position of the bar 18 the lower end portion of the needle 19 projects a short distance below the bottom of said plate 11 and through a guide aperture 23 (see Figure 9) in an arm 24 of a presser-foot 25, which latter has an annular foot portion proper 26 that is split, as at 27, with an opening sufficiently wide to permit the stitching thread to be passed therethrough, as will be later more fully described inconnection with the operation of the machine. y

Sleeved on the tubular member 14 is a member comprising an annular lower end por tion 28 and a split annular upper portion 29 that are connected on opposite sides of said tube 14 by parallel longitudinal members 30, said longitudinal members 30 having dianietrically-disposed, transverse apertures 31 for the reception of trunnions 32 of an operating lever 33, to be presently more fully described. The split upper portion 29 is provided with apertured ears 34, one of which is screw-threaded, and said portion 29 is clamped to the tube 14 by a screw 35 that is applied so as to dra-w said ears 34 together. In this way the said member is capable of adjustment on the tube 14, yet it may be readily secured in place.

The portion 29 has a rearward extension 36 that is bifurcated as by grooving it rectangularly (see Figure 6 of the drawings) so as to receive, with a sliding t', a carrier-bar 37, of correspondingly rectangular cross-section, which has the presser-foot 25 secured to its lower end portion, said bar 37 being retained in the bifurcated portion 36 of said. member 29 by a plate 38 that is held in place by screws Y39.

llO

The bar 37 has a transverse stop-pin 40 38 and whose upper end portion is attached to an angular extension 43 of a rod 44 er:H

tending upward from vthe end of said bar 37 (see Figure 5 of the drawings).

Coiled around the carrier-bar 37' is a spring 45 that is interposed between the extension 36 of the member 29farid the top vside of the head portion 7 of the standard arm 6 andk is always under compression so as to yieldably hold the tubular member`14` and the operating lever 33 in normal or raised position, acting to restore them to such position after cach operation thereof, the presser-foot 25 coming in contact with the under side of the plate 1.1 serving 'as a stop for limitingr the up# ward movement of said bar 37 and also that of the tube 14 owing to the arrangement of the stop-pin 40 that is engaged by said extension 36 of the member 29.l The presser-'foonas shown more clearly in Figures and 9, is

provided with a vertically grooved portion 46 to fit the bar 37 and is detachably secured to said bar by a screw 47. y Y

The operating lever 33k has an open frame or yoke portion 48 surrounding said carrierbar and tubular member 14, and in the side members'of said frameV or yoke portion are secured the above mentioned trunnions 32 which, as shown, comprise' pins or studs that are inserted in apertures' provided therefor in said frame or yoke 'si de members, said pins or studs being secured in place by sct screws 49, as shown in "F igure 7, At the Vouter end of said operating lever 33 is a handle portion 50 to be grasped by the operator in manipulating the machine,` while the inner end portion of the lever is fulcrumed,

' as by a pivot stud or bolt `51, on a bracket extension 52 of the arm 6 of the standard 5. 1n order to provide for'the straight up and down movement of the trunnions- 32 in the yoke portion 48, the operating lever 33 -is made telescopic between the aXis of said trunnions 32L and the fulcrum 51, by having a tubular section 53 fitted and secured tightly on a stem extension 5421s bya

cross-pin

5,5 or other suitable means, in which tubular section 53 is slidably fitted'a stem extension 56. By this construction and arrangement -an easy up and down'reciproca'tory movement of the tubular member 14 on the guide tube 13 Vis accomplished by the operator depressing' the lever against' the action of the spring 45 which returns the parts to normal position when the .lever is relieved of the down-v ward pressure by the operator.

needle 19 and the presser-foot 25 move downward simultaneously in their iiormalrelation as shown in Figures 1 and 5, and'continue in such relation until the presser-foot comes in contact with the pile of cloth,where upon the spring 41will`yield and'rpermit theA tubular member 14 to continuel on and drivetlie needle through the ile of cloth, thereby carrying a loo of `t e` stitching thread through the pi e andthence th'roughan opening 57 in the base-plate 1, the point of the needle reaching close kto the face of the worktable at the completion of the stroke. In this connection, it may be here stated -that the stitching threadmay betaken from any suitable source of supply, and the strand,

of course, is threaded through an eye provided in the needle near its'point, in-a manfner simi'lar'to any other sewing needle.

As Vshown in the drawings (see Figures 1 and 4) the stitching thread, indicated by the numeral 58, is supplied from a spool 59, as yindicated by the dotted lines, which is rotatable on a rod or stem 60 projecting upward from the standard 5, said spool resting on a disk 61 at thecbase oit' said rod or stem 60, and the thread being carried from the spool throughan eye 62 located above the ,latter and at the end oit a wire bracket member 63. From the eye 62 tliet-hread may be passedv through another eye 64 on the upper side ot' the arm 6 of the standard 5 near the vouter side of the base-plate 1 will now ,be` de scribed. j p v On the under side of the base-plate 1 is -a longitudinally slidable, fiat bar 65 which is `supported by two guide-plates 66, which latter are secured in place by screws 67 (see Figures'3, 11to VV13,*and 15 to 17, inclusive). rIhis bar is normally held yieldably in ietract'ed'positioii by a spring 68 which is secured at'one end to a stud 69 on said bai-fand at its oppositeend to a stud 7() on said 'baseplate 1.- 'Pivotally secured on the forward rend portion'ot said bar 65 isthe catcher element'71, which latter, in thergconstruction illustrated in Figures 3,- and 11 to 14, inclusivefhas a stud '72 thereon, towhichis attached one end o-ta spring 73 whose opposite end is attached' toa stud 74 on said bar 65. This spring 73 acts to yieldably hold lthe catcher element 71 in its normal retracted position against'astoppin or stud 75 on the base-plate l1, andv said catcher element 71.

lduring its respective actuatioiis, to be presently described, swings about its pivot 76,

n y I which latter, as shown, comprises a shoul- As the operating lever is depressedV the forth."

VGO

When the operating lever 33 is depressed by the operator, the tubular member 14 moves downward therewith on the guide tube 13, during which actuation the presser-foot 25 comes in contact with the topmost layer of the pile of cloth that is laid over the baseplate 1, while the needle 19 continues on downward through the pile and at the termination of its down stroke the point of the needle is in very close proximity to the top face of the work-table, as hereinabove first described.

Just before the point of the needle 19 enters the opening 57 in the base-plate 1, the catcher' element 71 is moved forward and is brought to rest substantially in the position shown in Figure 13 of the drawings. This is brought about by the actuation of mechanism interposed between said slide-bar and the operating lever 38, now to be described.

This mechanism comprises a rocking lever 77 that is pivotally mounted on the standard 5, as at 78 (see Figures 1 and 4), and is provided with a suitable spring-pressure device 79 to maintain some, although not excessive, tightness inthe pivot, which will olfer some resistance but not interfere with an easy operation of the machine. The lower end portion of t-his lever extends through a slot 80 (see Figures 2 and 15) in the base-plate 1 and normally abuts the rear end of said slide-bar 65 near one corner thereof so that the adjacent side face of said lever 77 and longitudinal edge portion of the bar are in substantially the same plane, as best shown in Figures 3, 15 and 16 of the drawings.

Y Pivotally attached to the upper end portion of said lever 77, as at 81, is a reciprocatory bar 82 whose forward end portion slides with both an endwise and up and down movement under a guide-plate 88 which is secured to the side face of the arm G of the standard 5 by screws 84 (see Figures 1, 4, 18 and 19). This reciprocatory bar 82 is yieldably held in normal forward position and with its forward end raised, as shown in Figures 1 and 18, by a spring 85 that has one end attached to a stud 86 on said arm 6 and its opposite end attached to another stud 87 on said barV 82. The forward position of the bar 82 is limited by a spring-stop member 88 on the standard 5 against which the lower end portion of the rocking lever 77 Anormally bears, said stop member 88 also serving as a cushion when the bar 82 is snapped forward after actuation as will be presently set forth more clearly.

The reciprocatory bar 82 has its upper edge portion notched by being cut away on an in-V eline, as at 89, affording a shoulder 90, said shoulder being engaged by the end portion 91 of ak downward right angular extension 92 of said operating lever 33 (see Fi ures 1 and 4) or, as shown in Figures 18 19, by

an insert 91a at the end of said member 92 of the operating lever, in which latter modification a wear-plate ais secured on said bar 82 coincident with the shoulder 90, both the insert 91at and the wear-plate 90a being obviously made of hardened metal to resist wear due to the frequent contact and rubbing action of the one part upon the other in the operation of the machine. V-

Normally, the end Jortion 91 or 91a, as the case may be, ofthe ever arm 92, sets some distance ahead of the shoulder 90 or wearplate 90a, respectively, of the bar 82; and the space between them isfso proportioned that, upon the down stroke of the lever 83 and just before the needle 19 has entered the opening 57 in thebase-plate 1, the lever arm 92 will have engaged the bar 82 and moved the latter rearwardly, thereby rocking the lever 77, which latter in turn pushes the slide-bar 65 forward, so that the catcher member 71 moves forward and at the completion of the down stroke of the operating lever it is in substantially the position shown in Figure 18. This actuation of the catcher shifting mechanism while the part 90 or 90a, as the case may be, isrstill engaged bythe part 91 or 91a, causes the catcher element 71 to move a slight distance further than the position shown in Figure 18, and, as the

part

91 or 91 rides in an arc of a circlefrom the axis of the operating lever, it is released in due time from engagement with the part 90 or 90a, at which time the hooked end portion 98 of a supplemental extension 94 of the lever arm 92 has swung downward into position ahead of a stop member 95 on the reciprocatory bar 82, and the instant said bar 82 is released from the lever arm 92 the spring 85 which has been stretched during this operation reacts quickly and draws the bar 82 forward until said stop .member 95 engages said hooked end portion 98 of the supplemental extension arm 94 of the operating lever (see VFigure 4 of the dra-wings). In some cases, in order to relieve the mechanism of shock, it may be preferably to provide, in lieu of the rigid hook portion 98, a spring element 98a that is secured at its upper end portion to the angular projection 96. of said lever extension arm 94, as at 97, said spring element 93 resting normally Hatwise against said angular extension 98 with its free end portion projecting downward so as to function like the above described hook portion 93. This spring element- 98ad is held against lateral displacement on said angular extension 96 by being provided with a longitudinal slot 98 through which projects a stud 99 from the angular extension, as more clearly shown in Figure 18. In connection with this modification, which is illustrated in detail in Figures 18and 19 of the drawings, the stop member 95 is provided with an undercut notch 95, with which latter mrt-ien said spring element 99* engages Q ki ligurellO 19) when the bar82 is snapped forward by said-

which latter member is then moved enldwise away from said bar 37 and its end portion is accordingly projected into the bore 22, as shown in Figures 5 and 10. This position of the block 109, of course, is limited by the slot-and-pin arrangement'between the block and theplate 11, and, therefore, in order to afford ample clearance of the lower end portion of the needle-bar 18, the latter is cutaway on the side thereof towards said block 109, as at 113, said cutaway portion having its face either tapered directly from the end of the needle-bar, or, preferably, as shown in Figures 4 and 5, extending for a short distance from `the end straight and substantially parallel with the longitudinal axis of the bar i and then gradually turning outward to the normal peripheral face of the bar, thereby forming a cam portion 114.

By the above noted construction and arrangement, the .presser-foot 25 travels downward ,simultaneously with the needle 19, as hereinabove described, inv substantially the same relation as shown in Figures 1 and 5, and until said presser-foot has been arrested by coming in contact with the pile of cloth and it' has compressed that'portion of the pile thereunder to a considerable extent` by the power of the spring 41, which latter yields and permits the needle to continue on through the pile of cloth. As soon as the cam portion 114 of the needle-bar 18 reaches the projecting end portion of the detent block 109 it acts thereagainst to move said blo'clrtowards the carrier-bar 37 ofthe presser-foot, and as the teeth 108 of the latter are engagedby `those 110of the block, the presser-foot is securely held in its contacting position with the pile of cloth during the completion of the down stroke ofthe needleand also duringthe return upward Vstroke of the needle until such time as the cutaway portion 118 cornes opposite the block 109, after which' the spring 41 is free to function in restoring the carrier-bar 37 to its normal position relative to the needle 19 and its carrierparts during the balance of the i up stroke. Thisobviously prevents the lifting of the presser-foot, in any case, no matter how thick the pile of cloth, until thevneedle has moved upwardly initially a distance to eiii'ect the opening of the loop of the stitching thread with Vsui'licient positiveness to insure it always being caught by the catcher element 71 upon eacli-actuation'of the machine. Vithout present invention, as far as the 'inventor is aware, the release of the catcher element from the loop of the stitching thread, after the completion of the stitch, is brought about ln this machine provision may be made for the manual release of the catcher element `from the loop of stitching thread and for restoring the mechanismV to normal condition, and, accordingly, for this purpose, the reciprocatorybar 82 is provided at its forward endwith a laterally projecting angular ex-` tension or ear 115 in cooperative relation Vto another like extension or ear 116 on the guideplate 83 (

seeFigures

1,4, 18 and 19 of the drawings) which may be grasped'between the thumb and forefinger of the operator so as to thereby press the ear 115 towards the ear 116 and in that way move the bar 82 rearwardly. and, of course, rock the lever 77 which inturn actuates the slide-bar 65 and moves the catcher element 71 forward to a position out of effective range of the stop rpinor stud 7 5, whereby said catcher element is swung, by theaction ofthe spring 73, laterally, as shown in Figures 13 and 14, and

In other machines of the character of the conveniently lll) whereby the catcher-needle or pin 102Y is withdrawn fromengagement with the loop of the stitching thread automatically diuring parts, or, in case the thread does not become -this last above describedactuation of theV so disengaged by the needle or pin 102, it is l readily pulled therefrom by the'operator if he keeps the two

ears

115, 116, pressed together as above described,`and with his other hand y pulls upon the looped thread'fromV above the `base-plate 1. In either case, the disengaged loop is withdrawn through the opening 57,V

by the operator. Y f

Provision` however, is preferably made for a substantially automatic release of the thread from the catcher element afterieach operation I t of making a stitch.A For this purpose, a latch element117 is pivoted, as at 118, on Ythe under side ofthe base-pl ate lalongsideyof the lower end portionof the rocking: lever 77 'and rear end portion lof theslide-bar 65 (

se'efFigures

3, and 16 of the drawings). This latch element is normally lpressed `yieldabl'y to'- wards said; rocking lever 77` and slide-bar 65 by a spring 119 which is secured -tightlyat one end bythe screw 67 that fastens-the rear guide-platef in place, while its free end portion` bears against an angular end extension 120 of the latch element. At the vsidey of the latch velement towards said rocking lever 77 and slide-bar 65 is a lateral projection121 af? fording a substantially square forward'shoulder 122,'and having a compound curvedrear portion 123 affording a cam surface.

Normally, in retracted position of the slidebar 65, the lateral projection 121of the latchv element117 bears against the edge of said slidevbar near the 'rear lendfthereof, and asthe sidel face of the `1'ocki`ri"g"lever 77 is `locate'd'praw tically flush with the corresponding edge of the slide-bar 65, any joint forward and back- Y, ward movement ofsaid rocking lever and slide-barl in their cooperative actuation 4will .not `p ermit any locking 'engagement Vof the latch member behind the end thel slide-bar. Thaty is'fwhen the rocking lever 77 pushes the slide-bar fforward, Las shown in Figure 15,

so as to bring the catcherfelen'ient 71 to the `-po sition shownfinFigure 13,l the lateral projection 121 of

Athe latch'element

1,1"17 is 'in slidable engagement'with the face lof saidrocking lever, and vupothe returnofv said rocking lever to-normal position and 1t being followed by the .slide-bar yunder the action of the spring 68, the slide-bar rides by said lateral projection 121- of the latch element without any interference thereby. However, if saidA slidebar 65'is moved forward independently of said rocking lever, as shown in Figure 16,then the lateral projection-121 of said latch element 117 snaps behindthe end of the 'slide-bar and prevents the return of the latter to normal positionv until released from such engagement. In this position ofthe slide-bar '65 the catcher element 7 1 is inl thefposition shown in Figure 14 of the drawings, inwhich ,position of the catcher' elementthe needle or pin 102is withdrawn from the loop ofthe stitching thread.

Therefore, it is'obvious thatj if the loop ofthe thread, while still engaged by lthe catcher element 71- and the latter isinits retracted position as shown in Figures and 12, is pulled drawn forward with 'the catcherelement 71 in a position slightly ahead offthat shown in Figure 14 of the dra-wings,or, in other words,

Y with the needle -or'pin 102V just about inregislofthe spring the catcherelementis subsaid slide-bar is just a short distance'ahead of lthe lateral projection 121 of the latchelement 117, so that the latter is free to move behind the slide-bar and thereby stop the latter from moving back tojnormal position whenthe operator lets go of the thread o r'permits it to becom'eislack between his hand and the catcher-needle or "pin 102. Therefore, when the operatordoes Vrelease his hold on thethread or.

permits it to becomeV slack asabove set forth, the needle vor'piri 102'is released from engagement .with the loop of thread as thespring 7 8 *swin s the cateher'element 71 to the angular position shownv in Figure 14 of the drawings,

A From the above it is clearly apparent that and,obvi'ously, the looped thread is then freeh lto be withdrawn out through the opening 57. K z

a substantially automaticrelease ofthe thread v from thev catcher element is readily Vaccomplished the operator merely pulling' upon the looped thread after the stitch is completed,

then easing up and .slackening the thread,V

vafter wh-iclithe loop is withdrawable at will.r j

.In this connection,` it may be here stated Y. l l that, with thefpartsstill in the position shown jinFigures 14 and 16, after the thread has been withdrawn las above described the vmachine can be operated to make the next succeeding stitch without restoring the partsto their normalacondition .as shown in Figures 3,11 and '12, because, when the rocking lever 77 is actuated upon the 'depression of the'operating ,lever"`33, `as firstabovev described, vits'lower end portion, during the forward movement" y"thereof, first engagesthe cam portion 123 Iof `the'lateral projection 121 of the latch element I 117 thereby swinging the latter so as to move ,the shoulder 122 from behind the Slide-,baly 65, and the continued forward movement of t'he rocking lever 77 inl engagement with said slide-bar 65 moves the latter forwardy as first leased frompthe catcher element 71 bythe f Y Y above described in the operation of making l :the stitch.

manual operation effected lby vthe'operator pressing the ear'115 of the reciprocatory bar 82 towards the earl 116 `of the guide-'plate 83,

orthrou'ghv the processvof'pullingthe lsli'de- .bar 65 forwardby the loopfof thread-when f Vthe latter is hooked onthe catcher-needlefor pin A102as above described, the release of the" by the operator,fthe slide-bar. will vbe `thereby loop' of thread fromj said needle or pin 102, may also vbe readily and conveniently accomcarry thecatcher element 71 forward` asin,`

making the stitch, such operation ofthe op-j erating lever, of course, being made after the completion of the preceding stitching operation and after the cloth has heenreinoved from under the needle 19, which removal is readily accomplished by the opera-l tor pulling the pile and during which the looped strands of tliefthread slide through the pile. In this operation the operator can conveniently hold the cloth lwith ,one hand i V,while he manipulates the operating lever 33 with his other hand. Y r

From the foregoing it is clearly `apparent that the machine possesses all the advantages of those having only provision for the manual release of the thread loop from the` catcher element, with the further advantage of an automatic release thereof. j

lVhilefthe structure and arrangement of the catcher element 71, as hereinabovedef scribed, serves its purpose quite well in general, it may be desirableV in some cases, and possibly in all,.to modify its construction and arrangement somewhat. A practical modification, therefore, is illustrated. vin Figure 17 of the drawings, in which, in lieu of the stoppin 72 and the cooperating notched portion 107 of the slide-bar 65, the catcher element 71 is provided with lan arm y124 extending rearwardly in line withthe arm 100 thereof and parallelinf" the edge ofthe slide-bai' 65, said arm having a substantially right angular projection 125 at its end and beingspaced from the slide-bar when the arm 100 of the catcher element is in cooperative engagement with the stopfpin or stud in the normal rei tracted` position of said catcher element, as

shown in full lines in Figure 17. In this modificationthe arm 103 of the catcher element has itsonter end portion straight and substantiallyparallel with the arm 100, as at 126, the cam portion 105 being located ap.- proximately midway betweenthis end portion 126 and the base portion of the arm.:

The inner edgeport-ions, of the cam 105 and the end 126 of the arm are flanged, as at 127 so as to afford a wider bearing face to 7 b ride across the needle 19 and thereby further insure that the looprof the stitching thread will not open at that side of the needle.

In lieu of the helical spring 73,013 the first .above described stiiucture, an arcuately bent i wire spring 123 is provided 1n this modification, said spring 128 being obviously secured tightly to the outer end portion ofthe flange 127, byarcuating the end portion of the spring and squeezing it in a slit or groove vfprovided therefor in said flange, as at 129,

j the opposite `end portion of the spring being hooked in an aperture provided therefor Ain the slide-bar65,as at 130. j j i f lfhe respective positions of the catcherfelement just above described, correspondingto itsactuations in the operation of the Amachine as illustrated in Figures 13 and 111 of the drawings, are indicated by ythe dotted lines in Figure 17. 4

At this point it maybe stated that the opening in the ring portion 26 of the presser-foot 25,:aiforded by lthe slot 27, as shown in Figure9 of thedrawings is to permit the withdrawal :of the looped strands ofthe stitching threa'dfrom the ring readily and conveniently after the completion of the vstitch and in order to facilitate the severing of the thread on a cuttingdevice to be presently described.

Thisopening 27 also facilitates placing the .end portion. of the thread drawn through theeye oftheneedle 19 by the operator prior toy making astitch, over the top side of the ring, which would otherwise be ldillicult to do if thel ring gwere continuous and not split as shown, because the length of thread entend-V ing 'from theeye of the'needle, after severance of the thread following the'completion of4 the preceding stitch, would be hanging down through the ring and it would be quit-e troublesome to bring it back up through the ring to be lai d over the top side thereof is desirable and, in fact, practicallyV necessary in the proper operation Vof the machine.

`As shown in Figures 3, 15 and 16 of the drawings, a stop member 131, similar to the stop member 8 8 for the rocking lever 77 is located in abutting 'relation to jthe rear end `ofthe slide-bar 65 inthe normal retracted positionof the latter, said stopmember 131 posse -'sii'ig a certain inherent resiliency so as to serve as a cushion whenthe slide-'bar 65 forcibly retracted by` the 'spring 68, and

' said stop member 131, by its relative location,

relieves the rocking lever 77 of considerable shock as the latter is thereby guarded from being struck directly byl said slide-bar 65 should the latter be snapped back to normal position at any time while said rocking lever is in its own normal position.

These two stop members SSand 131 may be ofany desirable form, but, as shown more vclearly in Figure 2 of the`drawiiigs, they the head'portion 7 of the arm 6 ofthe standard 5, asbyscrews 133 (see Figure), said bracket member projecting beyond the end of said headportion7 and having its ripper and lower-margins notched, as at 134-, with i upper and lower projeetions135` adjacent to saidnotches and over which projectionsV the thread'to be cut is hooked. Q

VCooperating with said bracket member 132 is a supplemental plate 136 corresponding in marginal out-line and shape therewith, and

between the two members132 and 136 an orizo dinany relatively t-liin safety razorblade 137 is clamped by a knurled:thumb-screwor other suitable fastener 138,;` saidf razor blade; at' fordingn euttingedges coincident with the l, notches :v 134E vso that ther thread may be appliedv eitherto the-top orund'erxsideof the s the annularlysv groovedfmiddlefportienr 139 the reo ior,` obviously,- said `thumb-screw may have-a transverse aperture 140 therethrough. andithrough which the threadlmay be-passed from saidguide lttosthe eye yof they needle.`
