TUGKING ATTACHMENT FOR SEWING MACHINES Application filed October 4, 1929. Serial No. 397,274.
This invention relates to improvements in sewing machines as used in stitching plaits and has as one of its objects to provide an attachment whereby the plait seams may be sewn at an angle with the fold of the goods, one end of the plait being wider than the other, thus producing as one instance a desirable, so called sun-ray eifect.
A further feature is in the provision of means for constantly varying the width of the plait in accordance with adjustments made predeterminately.
Another aim is to provide an indicator showing the proper point at which to start the seam.
These objects are attained by the novel construction and arrangement of parts as hereinafter described and shown in the accompanying drawings constituting an important component of this disclosure, and in which Fig. 1 is a top plan View of an embodiment of the invention, illustrating its application to a conventional sewing machine.
Fig. 2 is a side elevational view of the same.
Fig. 3 is a transverse sectional View taken on line 3-3 of Fig. 2.
Fig. 4 is a perspective view showing the 30 appearance of the work produced.
Fig. 5 is a side elevational view showing a modification in one of the elements.
Fig. 6 is a plan view showing the appearance of the work produced by the modication shown in Fig. 5.
Mounted on a platform 10 are upright posts supporting a. table 11 on which is a sewing machine 12 having a head 13, needle 40 bar 14, presser foot 15 and pulley 16 driven by a belt 17.
Fixed to the sewing machine shaft, adjacently beyond the pulley, is a sprocket wheel 18 driving a chain 19 trained over another 45. sprocket wheel 2O fixed on a shaft 21 rotatably mounted in double bearings 22 secured on the platform 10.
Another, longer shaft 23 is also journalled in the bearings 22, below the plane of the 59 table 11 and at the rear of the apparatus,
its outer end being journalled in a bearing 24 near the outer end of the platform.
Fixed on the shaft 23 are a series of spur gears 25-26-27-28-29 differing in diameter from large to small, and adjustably slidable on the shaft 21 are a similar series of gears 25-262728-29 selectively engageable with the first named gears so that the shaft 23 may be driven at different proportional speeds.
On the outer end of theshaft 23 is a worm in mesh with a worm wheel 31 fixed on a transverse shaft 32 mounted in bearings 33 and having fixed at its front end aI spiral cam 34.
A bracket 35 having opposed uprights 36 forms a guide for a sliding block 37 which has an angular projecting point 37l adapted to contact with the surface of the cam 34, being drawn against it by a tension spring 38.
A bent arm 39 is held by a yscrew to the inner end of the block 37, and engages a bar 40 slidably engaged in the lower parts of the uprights 36 and attached to the bar 40 is a rod 41 offset upwardly at its forward portion and provided with a pin 42 which passes through a block 47 and a pointer 43 pivoted on a pin 44 passing through a slot 45 in the pointer, the index end of which moves with relation to an index 46 on the table 1l. i
VA slide way 47 guides the block 47 to which is attached the end of the rod 41 that moves the pointer, and adjustably clamped on the block is a spring guard48 under which. the fabric moves Aover the table 11, the guard being slotted for the clamp screw 49.
Attached on the upper surface of the block 37 is a flat bar v50 carrying screws 51 passing through slots in the shank 52 of a' fabric guide 53, its forward edge being inserted between the folds of the goods X to be plaited, this edge being adjusted with reference to the needle carried in the needle bar 14, closely adjacent the table 11 and having a part 53 extending forwardly over the table.
In operation the fabric guide 53 is adf justed by the screws 5l to give the desired width of the plait at its narrowest portion, as at Y, see Fig. 4c, care being taken that the block point 37 contacts the cam 34 at its lowest portion, this being denoted by the position of the pointer t3 which should be on zero.
The pair of train gears 25-25 to 29-29' required for the particular' length of plait desired, are put in mesh, the proper size cam 34 which determines the height of the plait as indicated at Z, having been previously adjusted on the shaft 32.
Obviously the cam 34 can be changed to another having a greater or lesser throw, and the gearing readily adjusted so that one full turn of the cam is made during the complete stitching of one plait.
In the modification seen kin Fig. 5, an eccentric 5st is substituted for the cam 34 thus producing a continuously undulating row of stitches as indicated at 1V in Fig. 6, the apparatus in all other respects remaining as previously described.
Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in the construction, without the exercise of invention or coniiictin with the scope of the claims hereto appen ed.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is
