25 Claims. (01. 112-23) My invention relates to improvements in sewing machines, and more particularly has reference to an attachment therefor, adapted to provide for the automatic feeding and control of a strip of material, such as braided straw, continuously into the machine forming the body of a hat or similar article.
Heretofore it has been necessary for an operator to do this work by hand, thus requiring an operator at each machine, whereas this invention is intended to render this work practically automatic, so that one operator can attend to several machines, and in case of a break in the braid or other material, the machine will automatically stop, and likewise in case of pins joining broken sections, and also when the braid has run out. In other words, once the machine has been properly started and adjusted for a given size hat crown, for instance, it will automatically continue to viding the strip of material of, which the same is to be made is continuous and unimpaired.
Referring to the accompanying drawings, I'
have illustrated in Fig. 1 in perspective, parts being broken away, a suitable form of attachment embodying an application of my invention, and Fig. 2 is a diagram of the electrical connections. Fig. 3 is a top view of the device embodying an application of my invention, and Fig. 4 is a front view thereof in which several parts have been.
. omitted for purpose of clearness.
This invention accordingly consists in the method, system, combinations of elements, arrangement of parts and in the several steps and relation and order of each of the same to one or more of the others, all as will be illustratively described herein. The many novel features embraced in this invention are far-reaching in their scope and are applicable in many embodiments 40 other than that described, and I therefore do not wish to be limited except as indicated in the appended claims.
1 indicates part of a conventional form of sewing machine head, which is suitably supported upon the base 2, the lower portion of which may be projected as shown at 3 for mounting the driving motor and other appurtenances. 4, 5, indicate two discs perforated at the center to receive the rod 6, therethrough, said rod being bent substantially at right angles at '7, the longer leg of the same being provided with a loop 8, the end continuing through a hole in the post 9, as shown.
In starting to form the body of a hat, it is customary to first start the spiral of braided straw or the like by hand. After this has been done,
form the same of the proper size and shape, prothe partial disc thus formedis pushed on the' end of' the rod 6 from left to right against the disc 5, after which the disc 4 is pressed on against the partially formed disc or spiral of braid, and then a suitable clamping device such as 10, is attached to the rod as shown, to securely hold the spiral of braid between the two discs, but not so tightly as to prevent the rotation of the same therebetween. In starting, these discs 4, 5, are substantially horizontal instead of substantially vertical as shown in the view, thus presenting the partly formed spiral or top of the crown of the hat at its periphery adjacent the needle, so that the extending 'unformed strip of material feedsupon the partly formed spiral at the point where the needle operates, and when the proper diameter of the top of the crown has been completed, the discs then turn to the position shown in the drawings, to complete the side of predetermined depth, as hereinafter explained.
The unfastened strip 19 of material to be sewn extends from the presserfoot 11 in the direction of the operator over. the plate 12, and beneath the guide 13, passing downwardly below the, rod 14, and between the contact members 15, 16, through the guide loop 17, secured in the post 18. to the feel or source of supply.
The contacting jaws 15, 16, are retained beneath the base 20 of the standard 21, within- ,which tends to press the upper jaw 15 upon the strip 19, as 'it passes over the lower jaw 16, and these two jaws are electrically insulated by a" suitable block of insulating material, such as 23', so that in case the strip breaks, the jaws come together and close an electriccircuit, which operates a switch to break the circuit of the electric motor driving the machine, thus enabling the operator to properly connect the strip or braid before again starting the machine.
Another standard 24 is suitably secured to the base, as shown, and is provided with a bracket 25, which carries a support 26, which resiliently retains a ball 27, secured upon the rod 14, at the inner end of which is the knurled finger-piece 28, and at the outer end of which is a threaded portion 29, so that the crown of the hat while being formed, rests upon the same and in passing over the threaded portion 29, tends to feed rightwardly, looking at the drawings, so as to keep the braid in proper'alignment for the presserfoot and needle,- the upper resilient finger 30 bearing upon the crown to keep the same sufliciently in contact with the threads 29, to insure the feed accordingly. The bracket 31, secured to the plate 32, serves as a support for the insulated mounting of the contact members 15, 16;
The bracket or standard 9 also, mounted on the plate 32, carries the block 33, in which is rotatably mounted thedial 34, having a rod 35, secured to rotate therewith, said rod having an offset 36, substantially at right angles thereto, which crosses the path of movement of the rod 6, carrying the discs trical contact therewith. The loop 8 of this rod 6, travels upon the rod 3'1, having a hand-piece 38 for adjustment of the same, and said rod 37 may be secured in its adjusted position by the thumb-screw 39, passing through the sleeve 40, in which said rod 3'7 has its bearing, said sleeve being supported on the standard 41, and 42 is'a spring, one end of which is secured to said standard, and the other end to the loop 8, so that as the hat crown is formed, the rod 6 travelling-along the rod 37, turns the bend 43 therein according to the adjustment of the thumb screw 39, thus turning the discs 4, 5, from substantially horizontal to substantially vertical position, after the top of the crownof predetermined diameter has been formed, and thus forming the sideof the hat, and when the proper depth of crown has been formed, the rod 6 contacting withthe offset 36, of the .rod 35, closes the circuit which opens the motor switch, thus discontinuing further forming of the-crown after a predetermined depth has been completed. In order to predetermine the point at which the turn is to be made from the top to the side of the crown, a scale 44 is provided on the top of the plate 32, so that in adjusting the rod 3'7, the end of the hook 43 thereof is 'gaged with-reference to said sca e, which indicates the size of hat to be formed.
In Figures formed fabrication of braid or other suitable strip material. In making spiralled fabrications, such for instance as a separate brim, I use a center piece suchfor instance as of cardboard which is supported by rod 6 in the same manner."
as the top of a crown,and-the braid or other suitable material is spiralled around the periphery thereof until the proper diameter is completed, when the contact of rod 6 with offset 36 will discontinue the operation of the motor operating the sewing machine. In making straight fabrications of longitudinally joined strip material such for instance as a band or belt, the forming fabrication is supported by either red 14 or finger 30 and kept against guide 13 in proper alignment for the needle, by rod 6 tensioned by spring 42, until the contact of rod 6-with offset 36 will stop themotor thereby alsoindieating that the proper width of the band or belt has been completed.
Figure 4 illustrates how the crown is automatically formed and the sewing machine continues uninterruptedly during the movement of the loop 8 around the bend 43. Spring 23 is adjusted to suitably tension the strip material 19. When the proper diameter of the top of the crown has been completed, the movement of loop 8 around bend 43 causes the rod 6 to assume the position indicated by dotted line so thereby automatically shaping the crown fabrication indicated by dotted outline 61, while the sewing operation continues Tuninterruptedly. the sewing continues and strip material 19 eeds upon the forming fabrication 61, the rod 6 progresses to the position indicated by dotted line 62, thereby shaping the fabrication to the form indicated by dotted optline 4, 5, in order to'make elec- 3. and 4,' 59 indicates the partially is greater than between rod 6 and loop 8. It will of course be understood that rod 6 and bend 43 'may be of any suitable form and size. 64 indicates a form of rod 6 for supporting a hat while the brim is automatically formed of spiralled strip material, and the dotted outline 65 indicates the forming. fabrication. The rod 6 exerts a pull upon the apex of the forming fabrica-.
tion 59, in a direction opposite to that in which the sewing machine moves the fabrication and the strip material as the successive sections of strip material 19 are spiralled thereon, theotherparts of the device being suitably adjusted so that the rod 6 exerts a pull sufllcien't to keep the periphery of fabrication 59 againstguide 13 and in proper alignment for the needle as the sewing machine operates. the axis of rotation of the fabrication 59 is below the stitching point 66 in the direction of feed of the strip material 19.
The motor circuit is indicated by the reference characters 45, 46, and these terminate in binding posts 47, 48, the binding post 47,being provided with a spring 49 carrying the keeper 50, said spring normally keeping said keeper downwardly upon the contact point 51, of the binding post. 48, thus keeping the motor circuit normally closed. This keeper is pivotally mounted in the bracket 52, by the pin'53, and is susceptible of the action of the magnets 54, 55, which are in the battery circuit 56, 57, which said circuit alsoincludes the contacting rods 6, 36, and the contacting jaws 15, 16, so that when contact is made at either of these points, themagnets-being energized, lift the keeper 50, breaking contact .at 51,
thereby discontinuing the operation of the motor which remains inactive until the circuit is again opened at the particular point where it was closed, as aforesaid. The spring 58 also serves to keep the right end of the keeper 50 down upon the contact 51, and may replace the spring 49, if desired,
orbe used in conjunction therewith as shown. I
A suitable diagram of the electrical connections is indicated in Fig. 2, wherein it will be observed that the motor, motor switch, and automatic cutoff are connectedin series, likewise the magnets, contact jaws, and battery, and in multiple with the latter, the cut-off for determining the size of hat to be formed.
Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
