SIXT Nov. 1 8, 1958 SEWING-MACHINE WITH ZIGZAG 0R ORNAMENTAL STITCHING ATTACHMENT Filed Dec. 27. 1954 5 Sheets-Sheet 3 IN VENTOR fia/za Jzlzzj ATTORNEY5 SEWING-MACHINE WITH sZIG'ZAG OR 1 ORNA- MENTAL STITCHING ATTACHMENT Hans Sixt, Zurich, Switzerland, assignor to Heinrich 'Gelhert, Zurich, Switzerland or ornamental stitching attachment, by Which at'least the needle-bar can be influenced by atleast one exchange- .able cam disc so as to eifect alterations in the lateral zigzag deflection and also to displace it to the left or right of the straight seam.
The zigzag or ornamental stitching attachment according to the invention is essentiallycharacterized by meansthrough which, after positioning the cam disc in any desired Way on its driver axle, the coupling of both parts .and contacting against the disc of the tracer connected to the needle-bar, take place automatically upon starting the machine.
Further features of the invention will "be evident from the claims, the specification and the drawing, wherein a preferred form of embodiment of the attachment is illustrated purely by way of example.
In said annexed drawing:
Fig. 1 is a side elevation of an over-hanging arm of a sewing-machine with the zigzag or ornamental stitching attachment;
Fig. 2 is a sectional view through a cam disc and its casing taken on the line AA of Fig. 1;
Figs. 3-6 are details of the attachment;
Figs. 7 and 8 are details of a variant of the embodi ment according to Fig. 3;
Fig. 9 is an exploded view in perspective ,and Fig. 10 is a perspective view of the cam disc holding casing.
The sewing machine according to the present constructional form has two externally accessible knobs (not particularly shown in the drawing), one of which acting upon the .zigzag attachment in order to adjust the stitch width, while another knobacts on the same attachment in such a way that the zigzag stitch may be displacedto the left or right from the zero position or the straight seam. A third knob acts upon the feed-dog and consequently serves to change the stitch length of the seam. By actuation of these knobs, zigzag stitches may "be changed by hand while sewing, both with respect-to stitch width, displacement of the seam, and stitch length, so that certain ornamental seams may be made, based on the known zigzag seam.
This manner of forming ornamental seams by means of suitable knobs generally attached to the overhanging arm or to the standard, has been known for a long time.
In more recent time also zigzag or ornamental stitching attachments have become known, in which the respective ornamental stitching seams are no longer made only by hand, i. e. by actuation of knobs, but automatically by insertable and exchangeable discs or cams. Very different kinds of such attachments are known, wherein the stitch width, displacement of the seam, and the stitch length may be changedautomatically by cams in accordance with a certain ornamental sewing pattern. Either the discs may constitute a fixed set with one to three cams, or a special insertable and exchangeable cam disc is available for each change (stitch width, displacement, stitch length). Each disc may be exchanged for another United States Patent 2,860,589 Patented Nov. 18, 1958 2 having one or several other-curves, in order. thus toobtain the different ornamental sewing stitches.
In the present form of embodiment there is provided only one exchangeable cam disc for altering the stitch width, i. e. the zigzag deflection and for .its displacement to the left or right of the straight seam, together with any desired varying within the track prescribed by the cam disk in use. In the present case, a .cam discfor the automatic change of the stitch length is not provided.
According to the illustratedform of embodiment the following means are provided automatically to .eifectupon starting the machine--the coupling of the driver axle with the cam disc placedlthereon with the machine at rest, and also automaticallyto bring about the contacting of the cam disc with the tracer connected to .the needle-bar.
In the arm 1 of the sewing machine casing there is an opening 2 provided on the side facing the operator. In said Opening is inserted and fixed a special casing 3 closed at the rear, and open in the direction facing-the operator, being however closable by means of a plate or cover 4 (Fig. 3). In the rear casing wall 3a the driver shaft 5 for discs or cams 6is journalled. Each cam 6,.has a circumferential flange 6d to permit the respective cam to be grasped by the fingers when it is to be removed or insertedin the machine. The end of the driver-shaft 5 facing the operator is designed as a stub shaft and adapted for mounting or changing thediscs, each with a different track. The other end of the driver shaft 5 carries a worm 7 meshing with a wormw'heel '8 of the arm or driving shaft 9. The portion of the driver shaft 5 adapted to receive the cam discs 6 has attached thereon a collar 5a which carries two diametrically oppositedogs 10 running parallel to the axis. The cam disc 6 which, by preference, may consist of any hard plastic material, has at its front-end, directed towards the casing rear wall 3a, a grooved cam 6a in which the tracer 12 engages and is positivelyguided, said tracer being associated with the needle bar 11 and describedas description proceeds. The cam disc 6 has two diametrically opposite tholes 6b, 60 parallel .to the .axis, which correspond with the dogs 10 of shaft 5. The dogs 10 and holes 6c, 6b of the cam .disc 6 serves to couple the twoparts. The opening in the casing 33 for placing the disc 6 onto the driver shaft 5 can be closed by the spring cover 41, being therefore on the one hand swivable round a hinge .13 on the flange 3b of the casing It, and, on the other hand, capable of being locked in the closed position by a spring pawl 14 with knob 15 on said casingflange 3b. For this purpose said flange 3b has at the respective pointa groove, While the pawl has a lifting face 14a. said cover, the pawl is lifted at the bottom of said groove and engages behind the flange .312 in the closed position. To open the cover, the knob is depressed, thus disengaging the pawl and the cover 4 springs up.
On the inner side of the spring cover 4 thereis ahelical spring 16 held by a screw 17 which, with .cover 4 closed, causes the cam disc 6 at first tosbear againstthe tracer 12. The tracer 12 which cooperates with the cam groove 6a can slide longitudinally and is under the action of a helical spring 21 tending to force the tracer 12 ,out wards, i. e. towards the disc 6.
The action and mole of using the exchangeable discs 6 .are as follows:
With the machine at rest and springcover 4 open, the cam disc 6 is simply placed on the driver axle without any definite positioning of the cam disc to be driven :by the shaft. When the disc .has been properly placed, the cover is closed, whereby the spring 16 presses the .disc .6 inwards and against the tracer 12. vNow the machine-is started, the driver shaft 5 being set rotating by the machine drive. But then the disc 6 is still checkedjbyits On closure of 3 lying against the tracer, until its holes 6c, 6b register with the dogs 10 due to the force of the spring 16. Consequently the coupling of the cam disc 6 with the driver 'shaft occurs automatically as soon as the machine is started. After coupling, the disc rotates with the shaft 5 so that now also the tracer 12 can fall into the cam groove 6a of disc 6 and normal operation begins of gorming ornamental stitches in conformity with the cam The feeler lever 18 having the tracer 12 seated thereon, can oscillate about a stationary axle 22 and is pivoted on a transmission member 23 connected to the sliding block 24 of a slotted link 25. On swinging the feeler lever 18 via tracer 12 away from the cam 6a around the axle 22, the sliding block 25 gets displaced in said link 25. Pivoted to the sliding block axle 26, which in zero position coincides with the axle 27 (Fig. 1), is the push rod 28 which in turn acts via joint 29 upon the needle-bar rocker 30, in which the needle bar 11 is caused to move up and down.
The slotted link 25 is rotatable about its axle 27 by means of a knob (not shown) located outside the machine casing. Instead of changing the width of the zigzag stitch through the knob, it is brought about through the cam 6a, according to the embodiment shown. By adjusting the knob, the needle deflection given by the cam 6a is varied correspondingly.
By actuating a second externally accessible knob, the seam may be displaced to the left or right of the straight seam, since the link 25 is oscillated about a swivel axle 31 located outside its axle 19, i. e. to the left or right from the Zero position of the knob or straight seam. The link axle 27 is in fact held by a lever piece 32 which can oscillate about the axle 31 fixed on the machine casing.
Pivotally mounted in the notched disk 33 seated on the axle of said knob is a bar 34 adapted to oscillate about a stationary axle 35. Pivoted at 36 to the arm of bar 34 is a lever piece 37 which embraces the axle 27 of the link 25.
On turning said knob (on the axle of the notched disk 33) into the two outer of three positions corresponding to the three notches in the disk 33, the lever arm 34a is raised and lowered. Thereby the link axle 27 is carried-on and oscillated about the axle 31. Incidentally also the axle 36 will be driven which is associated with the first-named knob for changing the stitch width. Therefore this knob is displaced according to the three positions of the second knob at the outside of the machine, which may be determined by marks thereon.
The said functions and movements of the parts, resulting from manual operation of the second knob for displacing the stitch will, according to the embodiment shown, also be provided for by the cam 6a, since disc 6 can act upon link 25 in the same sense via cam 6a, tracer 12 and also levers 18 and 23.
To permit the operator to inspect the fitted disc 6 even with closed spring cover, the latter may advantageously consist of some transparent or plastic matter, or it may have at least one orifice permitting a view of the positioned disc 6. Such a design is illustrated in Figs. 7 and 8. Thereby the closing metal plate or spring cover 38, hinged at 13' to the machine, is slightly convex outwards and has a rim 38a roundabout with two thickenings, each on a straight portion above and below. The cover 38 has two orifices 39, each covered by a transparent disk 40. Inside, each of said disks 40 rests on a thin marginal portion 38b of the spring cover 38. For securing the disks 40, each orifice is surrounded inside by a bead 4 1 which, upon insertion of the disk 40, is pressed flat at several places 42 so that said disk will thus be retained 'by enlargements as shown in Fig. 8 on a larger scale.
Obviously, said disks may also be retained on the plate in some other manner.
Through the invention a cam-controlled zigzag or ornamental stitching attachment is created, the chief merit of which resides in the fact that, when the cam disc has been applied, the seamstress need not trouble about its coupling; she has merely to put it on, to close the cover and to start the machine, whereupon the cam disc becomes coupled automatically. Opening of the cover will permit any fitted cam disc to be removed manually. A wholly or partially transparent cover will enable the seamstress at any time to ascertain what cam disc has been inserted and whether the same rotates with the driver axle upon operation of the machine, without her having to open the cover for this purpose.
