16 Claims. (Cl. 112`160)v This invention relates to sewing machine attachments, and more particularly to an attachment for effecting decolrative stitches in various patterns.

I In machines of this character it is usual to provide a frame portion attachable to the presser foot of a sewing machine, the frame carrying the mechanism of the attachment, which mechanism is operated by a fork arm actuated by the needle bar. Such decorative stitch attachments usually are provided with means for moving the cloth laterally of the line of feed of the sewing machine so as to provide zigzag stitches in various patterns. It is also desirable in such machines to be able to effect a certain number of stitches in a line and then move the cloth laterally and effect a given number of stitches in a line parallel to, but displaced laterally from, the rst series of stitches. One of the features of the present invention isto provide readily adjustable mechanism for producing decorative stitches of various patterns, the

mechanismfor changing from oner pattern to another being accessible to the operator and readily manipulated without disconnecting the attachment from the machine.

As illustrated a presser foot is carried by a lever pivotally attached to the frame of the machine, and this lever is oscillated by means of a cam having an internal cam track of sinuous form within which is received a pin or 'cam follower secured to the lever. The cam member is actuated by a fork arm mounted to oscillate on the frame and also actuated by the fork arm in a step-by-step movement is a bank of cams, the cams being formed or. cut differently so that each one will effect a different stitch pattern..

These cams are adapted through a train of mechanism to permit or prevent actuation of the internal cam member previously referred to by .the fork arm so that the particular type of stitch effected by the attachment is determined by the particular cam which is placed in operation.

One object of the present invention is to provide a decoy rative stitch attachment for sewing machines of improved form and one which is readily manipulated and adjusted.

A further object of the invention is to provide a decorative stitch attachment for sewing machines which is `capable of effecting a large number of stitch patterns and which may be set or adjusted to effect any selected one of a number of patterns.

Still another object of the invention is to provide a decorative stitch attachment having a presser foot carried by a lever pivotally secured to the frame of the attachment, this lever being actuated by the usual fork arm, and to provide a bank of cams which may be selectively employed to either permit or prevent actuation of the flever upon any given stroke ofthe fork, arm so as to icc effect a variety of stitch patterns depending upon the particular cam employed.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

Fig. 1l is a detail perspective view of the cam follower and its adjustingmechanism;

Fig. 12 illustrates three of the controlling cams employed; and

Fig. 13 is a perspective view of the controlling lever which is actuated by the cam follower.

As illustrated in the drawings, the attachment comprises a main frame member 10 of substantially U-shaped form to which is securedan auxiliary frame member 11 (Fig. 5) which is also of U-shaped form in cross section. Pivotally secured to the frame member 10 is a lever 12 carrying at its forward end a presser foot 13 which is adapted to engage the Vcloth andfeed the same laterally when the lever is oscillated. f

As shown, the lever 12 is pivoted upon a pin 14, which pin is adjustable in a slot 15 in the lever 12 and inl a registering slot 16 (Fig. 3) in the base of the frame 10. The pivot pin 14 is secured to an arm v18 of a slide member 19 shown in dotted lines in Fig. 4, whichslide member is provided with a slot 20 to receive a pin 21 secured in the base of the frame member 11 so that the slide may be guided in its movements. The slide is also provided with a vertically turned edge portion 22 provided with a slot 23 (Fig. 2) and an adjusting screw 24 passes through the slot 23 (Fig. 6) in order to frictionally secure the slide in any adjusted position. As will be obvious, adjustment of the slide and the consequent adjustment of the pivot pin 14 will adjust the throw ofthe lever 12. Secured to the lever 12 adjacent the rear end thereof is a cam follower 25 (Figs. 1 and 2), which follower is received in a sinuous or wavy internal cam track `26 of a cam member 27 rotatably mounted in the up'- standing leg portions 28 and 29 of the frame 10. This cam is secured to a shaft 30 and may he manually rol tated when desired by the knob 31.

The usual fork arm 32is pivotally mounted upon a shaft 33 so that it may be oscillated about the shaft. Secured to this shaft is a ratchet 34, the teeth of which are engaged by a pawl 35 pivoted at 36 to the fork arm 32, the pawl being urged into engagement with the teeth of the ratchet wheel by a spring 37 so that oscillation of the fork arm will effect step-by-step movement of the ratchet wheel and the shaft 33.

Pivoted at 38 to ltheV fork arm 32, which pivot p oint is eccentric to the pivot of the forky arm, is a link 39, which link extends rearwardly and is connected at its rear end'at 40 to anrear 41 of a lever 42 oscillatably mounted -on the axis of the shaft 30. Pivotally mounted on the lever 42 is a pawl 43 urged by a spring44 into engagement the teeth of a ratchet wheel 45 secured to the shaft 30 of the internal cam 27.

With the construction sofar tdescribed, it will be obvious that when the fork arm is.oscillated, ;the shaft will be rotated ina step-bystep`movernehtand .through v the link 39, 1ever42, pawl;43 and. ra'tjchet wheel: 45 .the cam member 27 will alsofrbe'rotatfed finastep-by-{step movement. This would .effecta zigzag or lateral stitch at each down stroke oftheneedle bar. .Howevenmeans are provided as will be hereinafter described to hold the pawl 43 `from engagement with `the ratchet. 45 when desired so `that straighhstitchng may be effected ingany desired pattern between zigzag or lateral stitching.. Also,

as will be described, means are provided to continuously hold the pawl 43 from engagement with `theteeth of the ratchet wheel so as top'roducestraight stitching, if ydesired. This means will now be described. L. e

Pivotedupon the frame member 28 at 47 (Fig.` 8), is a lever 48 shown more particularly in Fig. 13. This lever ismof curved form and is'providedrwith an upstanding L- shaped arm 49 which projects upwardly `below a pin Aor knob 50 secured to the pawl 43. When the lever 48 isrin the position shown in Fig. l, it is out of engagement with the pin 50,'fas shown in Fig. 9, and,` therefore, will permit the free end of the pawl member-43 to engage the ratchet Iwheel 45..Whenhowever, the lever 48 isin the position shown in Fig. 8, the arm 49 will'engage `thepin 50 and raise theipawl 43 from engagement withtheteeth of the ratchet 45,` as shown in Fig. of the drawings. e

, .The lever 48 4isprovided'with a pinr52 whichtprojects through an elongated opening 53in the frame member 28 and which is received in an elongated opening 54 in a cam follower55 having a rounded'end follower portion 56 to engage thetselecting cams as will be hereinafter described. `The ffollower `55 Vis also provided with an opening 57 `receiving a` pin `58 secured to theframe member 10 `and projecting .into theframe member 11 (Fig.V 3)` so-that `the followeris pivoted for rocking movement-upon this pin. With this arrangement it will be.v seen that as the 4follower-is rockedaboutits pivot, it will `swing the lever 48.about its pivot 47 dueto theengagement of the pin 52 inthe elongated opening54.

. .The follower 55 is provided with a bridge member 59, oneend; of which is secured to the follower `and the-other `endfof which1is provided ,t with a downwardly projecting ear 60 having `an opening 6.1. whichy also looselybut snugly receives, `thepin `,58.3 `Projecting laterally from4 the ear and). by va spring 68. `Theo'ther end of the `lever 65 Aisiprovidedwith .an adjusting .button 70 and is alsoprovided with a downwardly-projecting tooth 71 (Fig. 6) adaptedto` benreceived in; any one of aplurality of openings72 in; a' member 73 likewise secured to the .frame 11.

It willbe seen that as the cam follower structure, shown `in Fig. ll,.is=secured tothe lever 65 bythe headedpin 63, `adjustment of this lever about its pivot 66will move `the follower; structure laterally ofthe frame member 11.

Securedtto ther sh`att.33 whichcarries :the ratchet v34 and fork arm 32 :are a plurality ofjcams 75, 76 and 77 (Figs. 3` `and 12) and also a t cylindrical member 78. .These are,the.selectingcamsl-which serve to select 4the particular patternwhich it is desired to make, and it will .be notedthat the cam- 75.is.provided with two `notches or indentations 75, while the cam 76 is provided with four notches or recesses 76and the cam 77vprovided at diametrically opposite Aportionsewith two adjacent recesses pr.; notches 77A". Ift will be, of` course,`.understood .that

wheii'thetcam 4follower is moved toa position where .an arrangement .of recesses, or notches` desired may be gmade.

it engages this member (which is smaller in diameter YthanV the cam members 75, 76 and 77), there will be no movement imparted to the follower.

The lever 65 is also provided with a downwardly depending arm 80 (Fig. 5) provided with an opening 81 which loosely receives a rod 82 secured to the lever 48 (Fig. 13), which rod passesiloosely through openings 83 in theupStandng walls 28y and,29 of `theframe member 10. Therefore, Vwhen the'free `end of the lever 65 is raised bythe adjusting buttony 70, the rod `82 willlalsobe raised, swinging thelever 48 about its pivot 47. Thisiwill effect movement of the pin 52 about =thepivotpointi47 and `thus Vraise) the free end ofthe follower 55 dueto the engagement of the pin 52 in the opening 54 of the follower 55 and move the endportion 56' downwardly away from the selecting cams, as shown in Fig. 8.

It will be appreciated that if it were attempted to shift the follower l55 laterally while.` the end. portion 56,-was engagedin one of the notches 753,776 orf77, of one of the cams, such movementwould be prevented by Aengagement of the portion 56 with the side of an` adjacent cam. Thereforewhenever the lever 65 is `raised bythe Vadjusting button` 70 to vwithdraw ,the .downwardly projecting tooth 71 fromone of thenotches 72 inforder'. to

,shifttthe follower laterally,.the cam follower portion .56

.during the two intervening stitches the follower will ride upon the cylindrical surfaces of `the camwhich areof course, of greaterdistance from the axis than the bottom of the. recesses. When the follower drops into one of .the recesses,` `the follower `will vbe permitted to swing ,through a small arc in a clockwice direction about the pivot pin 58 and, vby the` engagement of the opening 54 in the follower with the pin 52 on thelever 48, will per- Vrnit` this lever to Swingin a clockwise direction about its Kpivot 47, and thereby permitting the arm 49 to move do,wnward1y,fas` shownin Fig.` 8, thus `permitting the spring l14,to-1urge ,thepawl 43` into engagement with-the ratchet 45 and impart a one-step movement to thesinuous `cam member 27,. This will` effect lateral movenient of thelever 12 about itspivot pin 14 and thuswilletfect a stitch laterally of -the line of stitches previously made.

Upon continued operation of the needle bar, the selecting cam 76 :willbe moved` throughfa Aone-step movement by the pawl 35 on the'fork'a'rm `SiZ'and the follower por- .tion 56 `willride up. upon -the .circular peripheral portion -ofgftheA cam, thus moving the follower 55 in a vcounterclocltwise dirctionaboutitsfpivot and likewise moving the lever .48in`the Asame direction due again to the engagement of 'the pin 5,2 jin the opening 54. This will `raisefthe `arm k49 of thelever 48 and move @the pawl 43 upwardly so that it"will` nollong'er engage the ratchet 45 and thusI the cam member"27`willremain stationary. Thusr straight stitching willA be'made 'for two strokes of .theheedle b ar until the follower por-tion 56 of the folllower55.eng`ages the `next recess 76` in the selecting camff76 when the cloth will'be moved laterally inthe opposite direction, and thefollowing two stitches willbe made in a line spaced laterally Afrom those previously `It willybel apparentfthat 'as thewcam 76'contains four "recesses 76, it Vwill `malte threestitches in a 'line,-'and vthen thematerial lwillbe shifted and-the Jthreefollowing stitches will be made in another line sp'aeedfrom and parallelto the 2tirst. In l'othter-lwords, -theuse-`-of this `cani will result intwo parallellinespeach containing-sets or groups of three stitches. If the cam 75'is employed, the same result will be obtained except that thetwo lines of stitching will consist of groups of six stitches. If cam 77 is employed, the result will be a group of five stitches in a line and then an oliset stitch, following which there will be another group of ve stitches in the same line as the first. n

If the cam follower 55 is moved into engagement with the cylindrical member 7S which is of smaller diameter than the selecting cams 75, 76 and 77, the arm 49 of the lever 48 will remain in its lower position, and the pawl 43 will be always in engagement with the teeth of the ratchet 45 so that a lateral stitch will be made at each stroke of the needle bar, thus making a continuous zigzag stitch.

As previously described, the follower member 55 is moved laterally to engage a selected one of the cam members or the member 78 by movement of the lever y65 to which the follower is connected by the pin 63. When it is desired to shift the follower from one cam to another, the adjusting button 70 is raised to release the .tooth 71 from one of the openings 72 which permits shifting of the lever 65. As also previously explained, raising of the free end of the lever 65 also, by means of the connection of the depending arm 80 with the rod 482 and the connection of the lever 48 with the` follower by means of the pin 52, will swing the follower 55 about its pivot so as to disengage the end 56 from the cam with which it has been engaged.. When the lever 65 has been shifted Yto the proper position, the button -7tl is released and the tooth 71 will drop into the corresponding opening 72 of the selected cam so as to hold the follower in the proper position.

It is, of course, possible to raise the adjusting button 7i) and permit the tooth 71 to remain supported upon the upper surface of the member 73 between two adjacent openings 72. This will hold theY end 56 of the follower 55 out of engagement with the cams and thus hold the pawl 43 out of engagement with the ratchet 45 so that the cam member 27 is not rotated and straight sitching will be effected.

The cam follower is urged into engagement with the selecting cam members by the spring 44 which engages the pawl 43. As will be seen from Fig. l0, the pin 50 connected to the pawl bears upon the arm 49 and thus tends to rock the lever 4S in a clockwise direction about its pivot and move the end 56 of the follower toward the selecting cams.

While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit lof the invention and within the scope of the claims.
