ADOLPHE VICTOR DESIIAYES, OF PARIS, FRANCE.

EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 462,858, dated November 10, 1891.

Application filed July 21, 1891. Serial No. 400,216. (No model.) Patented in France December 19, 1887, No. 187,687. and in Belgium December 20,18S7,I\T0.79,988.

T0 at whom it may concern:

Be it known that I, ADOLPHE VICTOR DE- SHAYES, of the city of Paris, France, have invented a new or Improved Machine for Sewing,Embroidering, and other Kindred Operations, (for which Ihave obtained Letters Patent in France for fifteen years, dated December 19, 1887, No. 187,687, and in Belgium for fifteen years, dated December 20, 1887, No. 79,988,) of which the following is a full, clear, and exact description.

This invention relates to a new or improved machine with shuttle and with universal feed provided with a needle, which may be made oscillating or fixed at times, according to the work to be done. This machine executes, as desired, satin-stitch or tambouring, scallops, overedge-stitch seams, zigzags, braiding, cording,beading, and top and bottom embroidery, &c., as hereinafter described.

In order to enable my arrangement of machine to be well understood, I have illustrated it by way of example in the drawings filed with this specification, in which Figure 1 is a general view of the face of the machine. Fig. 2 is a side elevation. Fig. 3 shows separately the arrangement of automatic tension for the thread employed in sewing. Fig. at is a side elevation of the driving mechanism of the needle. Fig. 4 is a detail of the shuttle and driving mechanism therefor. Fig. 5 is an end view of the apparatus for driving the shuttle. Fig. 6 shows particularly the arrangement of the shuttle. Fig. 7 is a horizontal section through the upper part of Fig. 8 is an under side view of the machine. Fig. 9 shows separately in section the devices for oscillating the needle-bar. Fig. 10 represents a modified form of said devices. Fig. 11 illustrates an arrangement of oscillating guide with a needle which is always fixed. Fig. 12 is a sectional elevation, on an enlarged scale, of the head of the machine. Fig. 13 is a detail in elevation of the cams 3 and the auxiliary parts. Fig. 14 is a sectional detail of the joint at the upper end of needle-bar. Fig. 15 is a detail showing the back of the levers which cause the oscillation of the needle. Fig. 16 is a detail showing a side view of the conical cam by which the needle is oscillated. Owing to its size, Fig. 2 occupies portions of two sheets.

As shown in the drawings, the driving-shaft 1, fixed in the head 2 of the machine, carries cams 3, which actuate the levers a to give the rising movement to the foot or presser bar 5, which draws the material in all dircctionsthat is to say, universally.

On the driving-shaft 1 is also fixed the plate 0, furnished with a roller 6, Figs. 12 and 13, engaging with a heart-shaped piece 7. This heart-shaped piece is fixed on the flat bar 8, which is surmounted by support 9, in which is supported the spherical end 23, Fig. 1a, of the needle rod or carrier 10, which is therefore free to rotate and oscillate, and which works in the interior of the central tube 11, Figs. 2 and 9. On this tube 11 are fixed the two twin levers 12, mounted on a collar 12. These levers serve to oscillate the needlecarrier 10 by means of a cam 13, that actuates a lever 11. For this purpose the lever 14, Fig. 7, terminates in a fork carrying two pins or projections fitted in the groove 1d of the tube 15, formed in one with a coned or tapering part 16, that acts upon the two twin levers 12. The two levers 12 are connected together at their lower end by two pieces 123, between which the needle carrier has its movement. (See Figs. 12 and 15.) These pieces are provided with two rollers 121 in contact with the needle-bar 10, and movement is imparted to them by a toothed wheel 17, driven by a pinion 18, keyed on the driving-shaft 1.

The cam 13 is mounted on a shaft 19, which carries the gear 17, and which is provided at its end with a flat part in order that this cam may slide over the same (while maintaining its connection, so as to be capable of being rotated thereby) by the action of a forked lever 20, Figs. 2 and 16, so as to change the working of the needle, either to vary the extent of its oscillation or for rendering it fixed or stationary. For this purpose the lever 11 is maintained constantly in contact with'the cam 13 by means of a pressure-spring 21, Fig. 1, whatever may be the position of the cam. The central tube 11, on which are mounted all the parts serving to transmit the oscillating movement of the needle, is provided internallyand at its lower part with a groove 22, Fig. 9, which extends only for a certain height on said tube. This groove 22 constitutes at the same time a guide for the needle-tube 10, which, as explained, is mounted at its upper end in support 9 by means of a socket-joint 23. The guide 24 is mounted on the lower part of the tube 11 and is provided with a spiral spring tending to press it upon the fabric. This guide (which maybe provided with an eye 24%, as shown in Fig.12) serves to exert pressure upon the material during the opening of the loop of the thread in. order that the shuttle may pass therein and form the stitch. It also serves as a passage for the materials with which are formed the embroidery and the stitches already mentioned.

As. the guide 24 cannot constantly be. in contact with the material, it is raised when desired-that is tosay, while the material is advanced by the. presser or foot. purpose the needle-carrier 10 isprovided at its lower end with asmall projection 26, as

shown separately in Fig. 4. This projection meets, duringthe ascent of theneediescarrier' 10, the projection 27 of the saidgnide 24, and this. causes the raising of thelatter. The rotary movement. is imparted to the central tube 11, as shown.- in Fig. 1, by means of a. pinion. 28, driven by another pinion 2.9, which shaft 36, arrangedin a support 37, fixed on the This pinion 29 drives a pinion 3.8,.

head 2; which actuates the pinion 39, Fig; 1, fitted on the support 37. The plate 40 is fixed onthe pinion 39-, by which it is moved. It is-furnished with the reels and with the threadtension. The support 9 has areciprocating movement and carries a vertical tube 41,

which is extended to a certain height, so as tosnrmount the plate 40-and to actuate the thread tension or distributor. This tube. 41 forms also a prolongation of the needle-can rier 1 0. The plate 40 also carries the reel 42' for the reception of the material necessary for embroidering. This plate is also furnished with the automatic, tension shown separately in Fig, 3. This tension consists of a-tube 44, provided with two conical buttons 45, one fixed and the other movable. They are designed to fix the reel 46 on the tube 44. This arrangement also comprises at one of the endsof the tube a fixed pin 47, on which engages the'point of the screw 48, which serves to give more or less tension to the reel. The other end of the tube is provided with a kind of piston 49,. upon which acts constantly acoilspring 50.

In unwinding from the reel 46 the thread For this for instance;

passes through the eye 51 to the. tension 52, th enin to thetube 41, andfinally to the needle. The material wound off the reel 42 passes first into the guide 53 and-then takes the same paths as the thread, so as to finally enter the holev 24 in the guide 24, in. order to obtaln upon saidnia'terial the various stitches above specified.

The horizontalshaft 31,which serves to 1mpart movement to the parts fixed on the head 2, carries a bevel-pinion 54, by which it receives rotary movement from a pinion 55, fixed on the vertical shaft 56. This shaft 56 also carries another bevel-pinion 57, engaging with a pinion 58, keyed on the horizontal shaft 59, which receives movement from the crank-handle 60. This crank-handlecarries which themotion of thecrank-ha-ndleGO is transmitted. to the horizontal shaft 59. shaft 59 extends under thebed-plate 6410f the machine. It isfurni'shed with aala-rgebevelpinion 65, gearing with-a central pin1o1 1: 66, upon which are mounted the parts requislte for the movement of the shuttle.

The pinion 66 is fitted in the support. 67,

fixed on the bed-plate 6 4, and is furnished atv its; center with a grooved rod 68,.actuated-by the forked lever 69, which carries for thispu rpose; two fla-trollers' 166, Fig. 8, engaged in the groove of therod. This rod 68 thus has a. reciprocating movement,which it transmits to the screw 7 0:E-hl0l'lgl1 the horizontal pin71,

attached to the-top of" rod 68, and extending, as shown, through-the helicalslots of screw 70. The screw 70 is-deigned toimpartthe circular oscillatory movement to the shuttle 7 2by means of the shuttle-driver 73, fixedtothe center of the screw, as shown in. Fig. 6. This shuttle and its shuttle-driver'work in a circular basin 7 4, Fig. 4 fixed on a frame 75, mounted thesupport and rotates with itin its circular motion. The screw 70 is mounted, as before stated, in the frame 75, and rotates. at itsupper part in' the basin 74. It. is, more.- over, fixed at. itslower part. by a point formed in one with the same.

For the passage of the needle, I provide the edge of thebasin. 74 with agroove 78.. This groove issimilar to the oblong groove. of the needle-plate 77,. as shown in Fig. 4.

The lever 69 is designed to operate the screw 70, and is fixed to the endof a horizontal shaft-.80, mounted intwo supports 81',formingone with the bed-plate 64. Thisshaft carries at its opposite end a crank-arm 82, at-

This needle-plate 77 isfixed on tached to the connecting-rod 83, connected to a crank-plate 81L, Fig. 7. This arrangement transmits the alternating motion of the plate to the lever 69, and thence to the screw 70. The plate 84 is fixed to the end of a shaft 85, which carries at the same time the pinion 86, Fig. 7. This piniongears with the pinion 87,, Figs. 2 and 7, for imparting continuous circular movement to the plate 84, which converts it into an alternating rectilinear movement. For this purpose the pinion 87 is mounted on the driving-shaft 1, whose motion it receives.

The engaging device 88 is one with the shaft 1, and consists of the parts necessary for this purpose, as in all embroidering-machines.

It is quite clear that I have described hereiuabove my machine in principle only, and that I am free to vary the details, forms, accessories, materials, dimensions, and arrangements of the same without changing in any wise the nature of my invention. Thus, for example, I may obtain the oscillatory movement of the needle by means of the arrangement illustrated in Fig. 10. In this case this arrangement dispenses with the vertical shaft 34 and the

pinions

32 and 33, and then the drawingpieces 35 are mounted directly upon the central tube 11.

The modification illustrated in Fig. 11 shows an arrangement with an oscillating guide a and a fixed needle. This guide is mounted on the central shaft 1) by means of a collar 0, and it acts on a cone (Z in the same manner as the twin levers 12 above described. Vith this arrangement the material serving for embroidering arrives through the central tube either through the orifice e and then passes into the hole f in thelower part of the oscillating guide a. Motion is given to this oscillating guide by the same parts, as in the case of the oscillating needle, and I thus obtain a straddling stitch on the material used for embroidering when I cause this guide to oscillate; but when I render this guide fixed this enables me to fasten the embroidery either at its center or on the side. This arrangement also enables me to embroider with chenilles, beads, braid, cords, &c.
