INVENTOR EMIL URSCHELER ATTORNEYJ' SEWING ll/IACHlNE WITH ZIGZAG ARRANGEMENT Emil Urscheler, Dietilton, Switzerland, assignor to Turissa-Naehniaschinenfabrik A. G., Zurich, Switzerland Application May 12, 1952, Serial No. 237,311

4 Claims. (Cl. 112-158) The invention relates to a sewing machine with zigzag device and has for its object to automatically perform certain ornamental seams by template control through the intermediary of an attachment to the whole mechanism for making the zigzag seam, for its lateral displacement to the left and/or to the right, as well as for the actuation of the feed-dog.

Thus the aforementioned entire mechanism should on the one hand be used with its setting and adjusting devices and, on the other hand, with its control by templates in conformity with certain ornamental seams.

To attain this object, according to an essential feature of the invention, the part-mechanisms-of which one serves to deflect the needle laterally, another to displace same to the left and/or to the right, and a third to actuate the feed-doghave allocated thereto an engageable and disengageable attachment by which at least one of the part-mechanisms can be controlled by following a template. Thereby the attachment comprises sets of cams exchangeable as templates, each set corresponding to a combined ornamental seam and of which the cams, in the engaged condition of the attachment are each contacted by a feeler or follower lever, one each of the levers controlling the part-mechanism for the needle deflection, that for the displacement of the needle deflection to the left and/or to the right, and that for actuating the feed-dog.

Further features of the invention will appear from the claims, specification and drawing which illustrates by way of example a certain preferred embodiment incorporating the invention.

In said annexed drawings:

Figs. l1-14 illustrate different positions of the displacement mechanism according to Figs. 9 and 10;

Fig. shows diagrammatically the different positions of the members partaking in the lefthand and righthand deflection of the seam.

Prior to disclosing the structure and operation of the object of invention proper, let first the structure of the three part-mechanisms be explained, of which one serves to drive the work feed, another to rock the needle bar laterally, and the third to displace the needle-bar vibrations laterally to the left and/or to the right.

Patented July 24, 1956 ice Regarding the feed-dog drive reference is made to Figs. 2-5. The motor vertically supported in standard 1 of the machine casing drives the main shaft 2 in the bracket arm via members (not shown). From the main shaft 2 via belt 3 the feed shaft 4 is driven in the free work-supporting arm of the machine. The shaft 4 in its turn drives via back gear 6 a shaft 7 with helical gear 8 having the loop taker (not shown) mounted on its axle 9. Seated on shaft 4 is an axially movable diagonal eccentric 10 being, via ball ring 11, in engagement with the fork 12a of a sleeve 12 through which the shaft 7 freely passes. The sleeve 12 embodies at its fore-part an arm 12b hinged to a bracket 13 having attached thereto the feed-dog 14 for the work-advancing movement. Seated on the forward end of the shaft 4 is an eccentric adapted to control the jointed bracket 13 and hence the feed-dog 14.

The diagonal eccentric 10 has an annular groove 1110 (Fig. 3) engaged by a fork 15 of a carrier bar 16 being at its free end, via linkage 17, 18 (Fig. 2) connected to an axle 19 (Figs. 1 and 2). This axle 19 is pivotally supported in the wall of the standard 1 and projects outwards; it carries a hand-grip 20 adapted to serve as pointer playing over a graduation scale 21. This partmechanism conventional in certain zigzag sewing machines for the drive of the work feed 14 functions follows:

With the hand-grip 20 in zero position as shown in Fig. 1, the mutual position of the ball ring 11 and fork 12a is such that the ball ring 11 centrically rotates about the axis of shaft 4 and thus transmits no forward or reverse movement to the feed-dog 14. Consequently, with the handle 20 in this position, the feed-dog 14 only moves up and down through the intermediary of eccentric 4a on shaft 4. On setting now the pointer 21), say, to position 4 of the graduation scale 4 (Fig. l) the axle 19 rocks clockwise (Fig. 2) and causesvia members 18, 17, 16a, 16-the diagonal eccentric 10 to move to the left (Figs. 2 and 3). Incidentally the ball ring 11 starts to run in an eccentric position to the axis of shaft 4 and imparts to the feed-dog 14-via fork 12a of sleeve 12 and brackets 12b and 13-an oscillatory movement vertically to the plane of the paper, thus bringing about the forward and reverse stroke of the feed-dog 14 and in conjunction therewith the normal movement of the work. The work-advancing or reversing movements caused by the feed-dog may consequently be adjusted by the handle 20.

As regards the part-mechanism for causing the needle to oscillate about a center line given by the lock-seam, together with the part-mechanism for displacing the oscillatory movement from the centre to the left and/or to the right reference is made to Figs. 2 and 9-15, in which the two part-mechanisms are interconnected.

From the main shaft 2 a bifurcated lever 25 is set swinging via a worm gear 22, 23 and an eccentric 24 fixedly mounted on the axle of the worm gear.

By means of a screw connection 26 the bifurcated lever 25 secured to a bush 27 rockably arranged in supports 28 and 29 of the machine frame. At the front of the. bifurcated lever 25 a slotted link 30 is rockably supported about a pin 31 on fork 25. Guided on a pin 32 in the path 30a of the slotted link 30 is a slide block operatively connected via link 33 with the needle bar 34 of the machine. Said link 33 is connected via axle 35 with the guide 36 of the needle bar 34 and its needle holder 37. The needle bar 34 or its guide 36 can be rocked about the rigid axle 38. This latter arrangement, diagrammatically represented in Fig. 2, together with the slotted link 30, 30a serves to perform and adjust the size of the zigzag stitch in a manner known per se in the art. The adjustment of different amplitudes of needle vibration is brought about by 3 a setting lever 65 (Fig. 1) adapted to play over a graduation scale 66 and by which the slide block in the main slotted link 30, 30a can be adjusted by transmission means not shown. V

In order to displace the zigzag scarn from its centre position in one direction, say, to the left as viewed by the needlewomen, i. e. to bring about the so-called 'lefthand and/ or righthand displacement of the zigzag seam from the centre position, the following arrangement is provided:

The slotted link 30, 30a rock'ably disposed about the pin 31 on fork 25comprises a slide-block39 secured thereon, having its axis 39aoutside that 4llbof the shaft 40 passing through the bifurcated lever 25 and its socket '27 and having on its other end a knob 41 operable from outside.

Theslide block 39 may either be cylindrically shaped as in Figs. 9, l-ll 3 or be given a square or rectangular section as in Fig. 14. Associated with the slide block 39 is another slotted piece a secured-in the shaft 40, say, by screwing.

According as to Whether'the shaft 40 is rocked clockwise or anticlockwise by means of the setting knob 41 (Figs. 1 and the main slotted link 30, 30a is caused, via slotted piece 42 and slide block 39 to swing out from the centre'position (Fig. 12) to the left.(Fig. 11) or to right (Fig. 13).

From Fig. 2the-transmission ofthe excursions of the slotted link 3% onto the needle bar is apparent. With the setting device (Fig. 12) inthe cent-re position,the pin 52 of the slideblock of the main slotted link '30, 30a is in the position I (Fig. which corresponds to the position Ia of the needlebar 34;--this beingtheso-called lock-stitch position' In the condition of the parts as in fig. ll (lefthand deflection), the pin 32 and the needlebar --34 are in their extreme leftha-nd position ll and'IIa, and in the condition'of the parts asinFig. l3 (rig-hthand deflection) in the extreme righthand-position=lll and Illa respectively.

The setting knob 41'ca-rriesaresilient member 43 which can fall into three stopnotches 44 (Figs. 1 and 10) determining the end position as-well as the centre position of the rock of shaft 40 and hence of the slotted link 42. These end'positions lie about-8 beforethe abutment-of the slotted link 42 in the'bore a of the fork 25.

After having described'in shorthereinbefore the various part-mechanismsfor drivingthe feed-dog, for executing the needle vibration about-the centre line (lock stitch) as well as the displacement'thereof to-the left and/ or right with respect to the centre line the attachment shall now be disclosed as to its structureand action.

As mentioned at the outset thisattachment-has for-its object to defiectthe-needle bar about the centre-line,-to displace this oscillatory movement with-respect thereto as well as to govern the drive of the feed-dog individually or combined by certain templates in orderto-obtain predeterminedforms of scam, say oi-namental seams. "For each of thethree different aforementioned-controls there is a template constitutedbythree different-camv disks-A5, 46, 47. These cam disks, removabl-yconnected to anaxle 48 (Figs. 2 and 6) areexohangeable for other cams giving different-forms of seam. Said a-xle 48 is mounted on a bracket 49 in the formbfa leverarrangerlfor pivotal movement about an axle 50 in the machine frame, i. e. as follows:

At the inner side of the standard 1 there is. an opening through which the bracket 49 with the axle 43 for receiving the cams 45, 46, 47 can be swung out from inside-the standard into the free space (Fig. 2)

On the other hand. the rnain shaft 2 has fixed thereon a worm 51 meshing with a worm gear 52 fast on an axle 53 rotatably .supportedin a bushing 54, Fig. 6, in standard 1.

In order tobring the attachment, i. e. the cams-into engagement with the whole mechanism,provision is made for a clutch (Pig. 6) betweenthe axle 48 with the cam disks 45-47, and theri-gid axlei53 of the machine drive mechanism. Associated with the clutch is an operating 4 knob 55 onshaft 50 for the bracket 49 for swinging the latter in and out. The clutch and the swing device for the cams is designed as follows:

The shaft 50, connected to the cam bracket 49, is pivotally supported in standard 1 by means of a knob 55 which projects out of the standard (of. also Fig. 1). Via its hub 49a the bracket 49 is connected for rotation with the shaft 50, but displaceable thereon in that between the inner front edge of the knob 55 and the bracket hub 49a a spring 56 is inserted which has the tendency to move the bracket 49 to the right (Fig.6). The axle 48 .is rotatably supported in the hub 49b of the bracket 49 and is intended to receive the cams 45-47. Mounted fast on the axle 48 is a disk 48:: having at its border a projecting pin 57. i I

It may still be mentioned that the cams 45, 46, 47 are integral and thus constitute a set of cams which may be exchanged for other such sets which are dikewise integral. The cam set 4547 :has a bore 58, throughgoing, to conform with the pin 57 of the disks 48a. Atthe-worm gear 52 a pin 59 is movable on a bushing 52a and under the influence of a spring 60. Said .pin 59 fits into the .bore 58 of the cam piece 45-47 (Fig. 7).

Gear 52 is secured on the bushing 54 and axle .48 is rotatable in the-sleeve 49b. The disk 48a is mounted on the axle 48. The cam 4547 is shoved on the axle 48 whereby the pin-57 will grip into the bore 58 of .the cam. The rotary motion from 52 with the cam 4547 is accomplishedby the pin 59 and spring 60 servesthe purpose to :impart-aspringaction axially.

The cam 45-47: is disengaged. in the following manner.

The knob 55 wilLbe pulled outto the left, Fig. v 6, wherebythe bracket 49 together with the hub 49a and 49b will-also-bepulled to the left. Thereby the cam .45-- 47 may also be moved to the left so thatthe pin i59 wi1l be free. Thenthe knob 55 willbe turned and thereby the bracket v49' together with the cam 4S--.47 will be swung out fromthestandard -1, as shown in .Fig. '2. The cam 45-47 can-now be removed and exchanged-for another-cam.

The replacement and coupling .of the new cam piece with the gear 52t-will takeplace in .reverseorder, that-is, knob 55 together with lever 49 will .rotate .backto the stop 55a whereby the cam with.the.pins 57.and.59 may be coupled in thebore 5H8.

The action of the coupling and the engagement and disengagement of the cam piece .4547. takes place inthe following way:

.A certain cam piece 4547. is placed onthe axle.,48.in such a way that its bore 58 engages with the pin -57 .of disk.48a. The axle 48 with the disk .48aand the cam piece put thereon are then turnednntilthe spring pin-.59 also engages the bore -58. :Thereby the cam piece .will be operativelyconnected with .the .driving axle 53 .and thus with the main shaft 2.

'The campiece 45.-47 is put on afterthe bracket 48 has been swung out into the free space. In this position the operator may conveniently place thecam piece or exchange same :for another cam. Withthecampiece put .on, the .knob 55 is turned clockwise until its stop 55a .enters the notch I (Fig 8). In thispositionthecam piece is swivelled into working condition, i. e., the coupling with the axle 53 may-takeplacevia worm gear 52.

.If the aforedescribed attachment is to be disengaged and the sewing-machine withits various arrangements set -to work-normally, thenthe knob 55 is shifted from positiongLinto position H. In so doing theknob :55 is somewhat pulled out and causes the-bracketv 49 with .disk 48a and pin 57 to move axially to the left (Fig.6 andr'l). The cam piece 45 47 follows this movement so that it will be disengaged from the spring pin-59 of the worm he 52- 'Again in th PCQQ F FQI d FlQ th bask '4 wit the cam piece 45-47 may be swung out of the standard by turning the knob 55 into position III '(Fig. 8), say, for replacing the cam piece by another, wherein re-engagement of the attachment with the new cam piece may take place in the manner described hereinbefore.

Then the tracks 4547 of the cam piece are con tacted by feeler or follower levers which act upon the various part-mechanisms. For contacting the cam 47 governing the drive of the feed-dog 14, provision is made for a double lever 18, 18a rockably mounted on axle 19 and which replaces the lever 18 in normal use of the machine. One arm 18 of said lever is associated with the actuation mechanism of the feed-dog via link 17 and carrier bar 16, 160, said mechanisms being stucturally and operatively provided in the manner mentioned at the outset. The other arm 18a of the feeler lever projects into the path of the corresponding track of the cam plece.

With reference to the needle movement of oscillation about the centre line (lock seam) or about the axle 38, the link 33, with the pin 32 seated thereon and associated via pivot point 35 with the needle bar 34, comprises an extension 33a to which the end of arm 61 of an angle lever is pivoted, said lever being rockable about a stationary axle 62 and the arm 63 thereof feels out the cam 46 of the cam piece. The cam 46 influences through these levers 61, 62, 63 the needle bar in a Way thereby given, that is with respect to the amplitude of the needle vibrations about the axle 38.

The curve 45 of the cam piece effects a certain displacement of the oscillations of the needle bar 34 about the axle 38, varying according to the shape of the cam. This is caused through a lever 64 having one end 64a (Figs. 2. and 9) secured on the auxiliary slotted piece 42., while the other end 64b (Fig. 2) projects into the path of the cam 45.

The invention makes it possible, according to the cams 45, 46, 47 of the particular cam piece set in, to produce combinations of seam forms, composed at will of the three groups of movement; viz:

1. The needle vibration 2. Its displacement, and 3. The movements of the feed-dog said groups of movement varying according to the shape of the cam in the course of one revolution of the cam.

It is not absolutely necessary that all three groups of movement be cam-controlled, but that one or another group of movement corresponds to the normal operation of the machine. In this case, for the corresponding group of movement, the cam piece should simply include a circular track which then controls in a normal way the part-mechanism of the related group of movement via corresponding feeler lever, but through the intermediary of the attachment.

Another merit of the invention is especially seen in the fact that for exchanging cam pieces the operator does not come into contact with the inner arrangement of the machine and has to open a part of the casing to replace same. She can disengage the attachment in a simple manner and bring the cam bracket outside the casing in a place where the exchange of the cam piece can simply be efiected separate from the actual mechanism.

By simple operation of the knob 55 the new cam piece of the attachment can be re-engaged.

Thus the operator is free to operate the machine under normal conditions for the template-like production of scam forms.

What I claim is:

1. A sewing machine with zigzag device comprising a standard having an opening formed in a side therein, a feed dog and drive for advancing the work, a needle bar pivotally mounted on the standard, a bracket lever pivotally mounted at one end in the standard and near the opening so that the lever may be moved out of the standard and through the opening, a set of cams mounted on the other end of the bracket lever, a drive mechanism for the cams engageable with the cams to drive the latter, mechanism in the standard connected to the needle bar to adjust the latter around its pivotal mounting, a second mechanism connected to the needle bar adjusting mechanism to displace the needle oscillations to the left or the right of a center line, a third mechanism connected to the feed dog drive to adjust the movement of the feed dog, a clutch on the lever pivot to disengage the bracket lever and cams so that when the clutch is disengaged the bracket lever and cams may be swung out of the standard through the opening to replace the set of cams for another set.
