Application filed August 29,1904. Serial No. 222,559.

To all IU/CtU/H/ it 'III/II/Z/ concern.-

Be it known that l, Monais P. Nassnnne, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful 1mirovements in Machines for Sewing Spangles on Fabrics, of which the following is a specification.

This invention relates to improvements on sewing-machines for cutting off spangles from suitable blanks and sewing the same on fabrics of various kinds. l have illustrated these improvements in connection with a universalfeed embroidering-machine as now in common use, resembling in its general construction a machine of that class described in Deshayes United States patent, No. 462,858, it being understood, however, that my improvements may be used in connection with any suitable sewing-machine.

The objects of the invention are to provide in connection with any suitable sewing-machine proper means for movinga blank, comprising a series or succession of partly-shaped spangles, into such a position relative to a needle and a cutting knife-blade that one of said partly-shaped spangles will be placed in the position with reference to the needle which it is to occupy while being stitched to the fabric, and at the same time to bring the line which separates it from an adjoining unlinished spangle directly underneath and parallel with the cutting edge of the knife-blade, and to also provide means for so actuating said knife-blade and the needle that in operating the machine a succession of separate spangles may be produced and stitched to the fabric in their proper relative positions.

Further objects are to provide for a revolving movement of the means for moving the blank and cutting off a spangle and for causing the same to take place simultaneously with the universal movement of the feeding device.

1 accomplish these objects by the means hereinafter specified, and set forth more par ticularly in the claims.

lin the accompanying drawings, forming part of this specification, Figure 1 is a side view, partly in section, of a universal-feed embroidering-machine embodying my improvements, while Fig. 2 is an end view of the machine with parts broken away, the needle being shown in a depressed position. Eig. 3 is a vertical section of the cutting mechanism and connecting parts, the needle appearing in its most elevated position. Fig. 4 is a rear view, and Fig. 5 a side view, both partly in section, of the device as illustrated in Fig. Fig. 6 is a top view of a blank containing a succession of unfinished spangles as may be used in connection with my improvements, while Fig. 7 shows a longitudinal section of a series of successive spangles as stitched to a piece of fabric by my improved mechanism. Figs. 8 and 9 show forms of blanks for producing therefrom modified forms of spangles.

Corresponding letters and figures of refer ence throughout the different views refer to corresponding parts.

In the drawings, 10 is the bed-plate; 11, the frame of the machine. .12 is the main drivingshaft, and 13 a parallel shaft carrying a pinion 1 1-, meshing with pinion 15 on shaft 12. 16 is the tubular needle-bar which receives its vertical movement from shaft 12 by means of eccentric 17, carrying a roller which engages with cam 18, said cam actuating slide 19, all in known manner and as shown in said United States Patent No. 162,858. The upper end of said slide, within which the needle-bar is allowed to revolve, imparts up-and-down movement to the needle'bar.

20 is the needle.

21 is a tube surrounding the needle-bar and capable of revolving horizontally within its bearings 22 and 23 in brackets attached to a face-plate 24 on the head of the main frame, but not capable of vertical movement. The lower end of said tube has attached to it a socket-piece 21, from which extends downward a projection 25.

26 is an annular feeding-foot for drawing the fabric toward the needle. Said foot gets its rising movement from a cam 27 on the main shaft, which cam actuates elbow-lever 28, the lower approximately horizontal arm 28 of which moves sliding bar 29 vertically along face-plate 24:, bar 31, carrying feedingfoot 26, being fulcrumed at 30 by a universal joint to a sleeve 32, fixedly attached to sliding bar 29, tube 21 being adapted to revolve within said sleeve. lvlovement for feeding the fabric is imparted to the feeding-foot in the direction of the arrows in Fig. 2 by swinging bar 31 around its fulcrum in usual manner by a mechanism which embodies slide33, provided with a horizontal tJ-shaped arm which engages with a groove in a sleeve 33, capable of sliding and revolving around tube 21.

Said slide, as common in machines of this kind, is actuated by a suitable cam (not par ticularly illustrated in the drawings) and travels along face-plate 24:, whereby the upper arm of lever 34, is actuated in usual manner, so as to travel along a cam-surface on sleeve 33 and to cause its lower arm 34: to move the collar 35, rigidly attached to bar 31, in the direction of the arrows. 35 is a shoe carrying the fulcrum of lever 34. The same is fixedly attached to tube 21. The inner surface of collar 35 forms a cam, so as to allow leverarm 34 to travel along the same when tube 21 is being revolved and to thereby give to said collar motion lateral to said arrows, and thus to procure in usual manner universal movement of the feeding-foot.

The shuttle mechanism 36 underneath cap 37 in bed-plate is of usual construction, similar to that described in United States Patent No. 162,858, above referred to, or to any other shuttle mechanism by the aid of which the ordinary lock-stitch will be produced.

The fabric to which the spangles are to be sewed is indicated by F.

Pinion 38, provided also with lower conical teeth 39, is fixedly mounted on tube 21 and meshes with a pinion 10 on an auxiliary shaft 11, which shaft also carries a pinion 12, mesh ingwith a pinion as, which is fixedly attached to a plate 14, needle-bar 16 being adapted to slide through a central perforation in said pinion 13. On plate 44 there is mounted a thread-reel and thrcad-tensioning devices 46 of any suitable construction.

17 is a tube fixedly attached to plate M and surrounding the upper portion of the needlebar, both tube and needle-bar having corresponding side openings for passing through the same the thread which is fed to the needle through the interior of the needle-bar. The upper end of tube a7 and the upper end of needle-bar 12 are open.

48 is a bracket fixedly attached to said tube, upon which is mounted a reel 19, having wound upon it a strip 50 of the configuration shown in Fig. 6, such strip being made of celluloid, gelatin, metal, or cloth, or any other suitable substance, and being so shaped that by cutting it along lines :1? in complete and separate spangles S will be formed. One or more additional reels, as 50, may carry tape or strips of material that are to be attached to the main fabric simultaneously with the sewing to it of the spangles, and the strips wound upon said reels are passed through the upper mouth of the needle-bar to a side opening 52 therein and a side opening 53 in tube 21, the strip 50 being passed to asmall roller 54, provided with projections 55, which are arranged to engage with the perforations 50 in strip or blank 50. The shaft 56 of said roller is mounted upon a shoe 57, having a base B, which shoe is fixedly attached to an extension on projection 25, and to one end of said shaft is attached a ratchet or having as many teeth as there are projections on said roller, while on the opposite end of said shaft a similar ratchet 57 is provided in engagement with a spring 58, attached to extension 25 so as to steady said roller. Projections 55, entering perforations extend close to base B, so as to prevent sliding of the blank between said projections and said base.

59 is a sleeve adjusted to slide upon the lower end of tube 21 and having at its lower end a projection 59, to which is attached a cutting-blade 60, so positioned that as perforations 50 in blank 50 engage with projections on roller 54 said blade, Which is placed close to the end of base B, will come directly over one of the dividing-lines w m, while needle 20 at the same time will pass through an adjoining perforation 50, so as to steady said blank during the stitching and cutting operation.

61 is a spring-actuated pawl hinged to projection 59 and adapted to engage with the teeth of ratchet 57, so as to impart sufficient revolution to roller 54.- to move the blank to the needle to the length of one spangle. Up-and-down movement is imparted to sleeve 59 by a claw 62 in engagement therewith and forming the lower extremity of a slide 63, traveling along face-plate 2 1, which slide is actuated by an elbow-lever 6a in engagement with a cam 65 on auxiliary shaft 13, said cam beingof such configuration as to impart downward movement to the cutting-blade and to the pawl only after the needle has started on its downward travel and after the shuttle makes the loop underneath the fabric and to arrest such movement of said parts before the needle completes the stitching operation.

66 is a ring made of rubber placed underneath the metallic feedingfoot and fixedly attached thereto. The end portion of the blank in engagement with the needle is pushed over the spangle just previously attached to the fabric underneath it, so as to produce stitching, as shown in Fig. '7, wherein the threadT forms loops, in each case passing through a perforation in one of the spangles adjoining the following spangle and engaging underneath the fabric with the shuttle-thread T.

For the purpose of being able to move the blank 50 to the needle in adirection different to the direction of the feed of the fabric produced by feeding-foot 26, as indicated by arrows in Fig. 2, and to adjust the travel of the shuttle accordingly I employ a lever 67 with a handle 68 for revolving shaft 69, carrying cog-wheel 70, engaging with a cog-wheel 71 on a shaft 72, which carries a rear cog-wheel, (not shown,) meshing with cog-wheel '73 on shaft 7 1. Said shaft is provided with a cogwheel 75, meshing with cog-wheel 7 5 for revolving the shuttle mechanism, and with a cog-wheel 76, meshing with a cog-wheel 77 on shaft 7 8, which also carries a cog-wheel 7 9, meshing with a cog-wheel 80 on shaft 81. The opposite end of said shaft is provided with a cog-wheel 82, meshing with teeth 39, and it will be seen that by means of these gearings the turning of handle 67 will produce simultaneous revolution of the needle-bar, as well as of tube 21 and of the mechanism for feeding blank 50 to the needle and for cutting otf spangles therefrom and also of sleeve 33 and connecting parts, whereby universal movement of the feeding-foot will be produced.

29 is a spring for forcing down the feeding foot 31 after it has been raised by its cam mechanism.

Spring 38 raises slide 33, and spring 6 X raises up slide 63 after said slides have been actuated by their respective cam mechanisms 83 is a connecting-rod mounted on a cam on shaft 12 in such manner that as said shaft revolves it will actuate a horizontal lever 84-, which partly revolves shaft 85, thereby swing ing a horizontal lever attached to said shaft, the arms 86 of which engage with studs 87 on a collar 88, within which revolves the bar 89 for revolving shuttle 36.

.l do not wish to confine myself to the details and detail combinations herein described, as it will be readily seen that the same might be varied materially without departing from the spirit of my invention, and I 1;)artieularly reserve the right to use spangles of any form that may be cut from a blank-as, for instance, diamond-shaped spangles, as 90, as shown in Fig. 8, star-shaped spangles, as 91, as shown in Fig. 9, &c.
