EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 451,831, dated May 5, 1891.

Application filed July 2, 1890. Serial No. 357,587. (No model.) Patented in France July 26, 1889, No. 199,818; in England September 20, 1889,1T0r14,874, and in Belgium October 1,1889,N0. 87,921.

T0 on whom it may concern:

Be it known that we, LEONARD L. MICK, MA- THIAS KURSTEINER, and EMIL IANENZ, the two first citizens of the Republic of Switzerland and the last a citizen of the United States, all three residing at Paris, in France, have invented certain new and useful Improvements in Embroidering and Printing Machines, (for which we have obtained patents in France, dated July 26, 1889, No. 199,818; in England upon an application No. 14,874, dated September 20, 1889, and in Belgium dated October 1, 1889, No. 87,921,) of which the following is a specification.

Our invention relates to an embroideringmachine which, besides preserving without any alteration the main features of the Swiss machines, (whether operating with discontinuous or multiple threads, as Heilmanns machine or with a continuous or single thread, like Rieters machine,) is provided with mechanism which prints the fabric in proportion as the embroidered design is produced thereon, and that without necessitating any alteration in the mode of operation of the embroidering devices, the object thus obtained being the manufacture of a fabric which, both by means of well-known machinery and by additional parts constructed according to our invention, is provided with a printed design fitting in, in any desired or predetermined manner, with the outlines and figures of the embroidered design.

This embroidering and printing machine is merely characterized by, first, a printing mechanism comprising circular dies movable about their center, the number of which is equal to that of the needles in the ordinary embroidering-frame and their center being on a line with the axes of the said needles.

To enable our improvements to be more readily understood, we have represented them in the accompanying drawings, as applied to the Swiss embroidering frame or loom, according to Heilmanns system.

The same letters of reference indicate like parts in all figures. The small letters refer to new parts and the capitals to the wellknown devices of the Swiss embroider-in g machine already alluded to.

Figures '1, 2, and 3 are full-sized views of the new parts, combined with the ordinary embroidering-frame. Figs. 4, 5, and 6 show at one-fourth full size the novel parts as applied to Heilmanns machine, which is represented in the act of printing a design upon suitable fabric. Fig. 1 is a side elevation of the printing mechanism in the position which it assumes when printing and while the dies are supplied with color or ink. Fig. 2 is a front elevation of the printing mech anism, wherein the dies are operated by means of the rack 9. Fig. 3 shows the same mechanism in the identical position, but with the dies operated by pinions arranged between each pair of toothed wheels f, inclosing the dies 6. Fig. 4 is a side elevation of the two curved fames of the ordinary embroidering-machine brought near each other to enable the printing devices to print upon the fabric L, stretched upon the movable frame I-I. Fig. 5 is a front elevation of the printing mechanism supposed to be operated by pinions interposed between each pair of gear-wheels f, each of which wheels surrounds one of the printing-dies e; and Fig. 6 is a front elevation of the printing mechanism, supposed to be operated by means of a movable rack g, which acts upon each of the gear-wheels f, surrounding one of the printing-dies.

The printing mechanism, Figs. 1,2, and 3, consists of a support or-bracket q, rigidly secured to the horizontal rod A of the embroidery-machine by means of one or more screws (1 This support extends upwardly and is provided with an eye 1" to receive the pivot of an arm provided with a projecting finger p, which rests against the vertical side of the support q when the printing-dies e are vertical. This arm 19 constitutes the support of a T-shaped bar, the Vertical wing Z of which supports the dies, the surrounding toothed wheel f and the rack or the pinions, as the case may be, operating the said dies. The vertical wing or arm Z is perforated in such a manner that in front of each of the needles y of the frame there is an opening through which the shaft or spindle h of a cog-wheel f may pass, the said wheel f being provided with a small concentric recess for the reception of the circular die 6, which is adjusted and secured to the said wheelf by means of a pin f and retained in position'by a thin latch f. Upon the shaft h of the wheel f is secured a ratchet-wheel h, having, preferably, twelve or sixteen teeth, according to the number of difierent positions which it is desired that the dies e should be adapted to assume. WVith the teeth of this ratchet-wheel h a pawl 70, operated by a spring is constantly engaged in such .a manner that the motion of the rack g or of the pinions g, interposed between each pair of toothed wheels f, causes these wheels to turn only onetwelfth or one-sixteenth of a complete revolution at a time and that the dies'are invariably stopped at the same point or in the same position during the printing operation. Thus by pushing the rack g or by rotating any one of the pinions g, as the case may be, all the dies 6 are simultaneously set in motion upon the horizontal bar Z. Vhen the printing is stopped and when the embroidering is to he proceeded with, the arms 19, along with the whole of the mechanism they support, are turned back on their pivots 1' onto the eccentrio-shaft Q of the machine, whereby the embroidering-needles Y are released and enabled to perform their work upon the fabric L in the ordinary way.

Upon the rail or bar A of the frame 0,

Figs. 4, 5, and 6, opposite the rail or barsupporting the printing mechanism a support q is arranged similar to that shown at q, the upright portion of which is also provided with an opening or eye 1", wherein the arm 19 is pivoted, which arm supports aT- piece Z, upon which a flexible pad e is placed opposite each of the dies e, so as to form as many counter-dies as there are dies opposite.

It will be understood that printing mechanism such as described is arranged both upon the upper and lower rods or rails A of the curved supporting-arms O of the ordinary embroidering-loom, both of which vided with needle-holders.

The operation of this embroidering and printed designs printing machine, producing exactly concordant with those obtained by embroidering, is as follows: In front of the needles Y, held by the ordinary holders P,

the arm p is first turned on its pivot "rin the bracket q, so as to move the printing mechanism into a vertical position that is parallel to the fabric L, upon which the designs are to be carried out, and which is stretched in proper position upon the frame II. In the same way opposite the needle-holders P on WVhen the carriages I, rolling by means of 1 the wheels F upon the rails or ways G, have carried back the curved arms 0 behind the fabric L, the ink may be applied to the dies ape are proin any preferred manner. hen ink has thus been supplied to the dies 6 and to the counter-dies e, turned against the said dies (2, and having been brought near to the material to be printed upon by the left carriage being moved toward the frame H, the right carriage is now moved toward the fabric with greater or less speed, so that the dies are brought in contact with the material and im print thereon the designs with which their printingsurface is provided. The carriages are then moved away from the material or fabric L, and the latter may then be shifted in the ordinary manner in accordance with the set shape of an operating-pantograph controlling the frame H, which carries the fabric L,'whereupon a fresh supply of ink having been conveyed to the dies 6 the carriages I are again brought near the fabric L, and an impression of the same design in the identical position is obtained in another part of the fabric. W hen the designs formed upon the dies 6, Fig. 2, are not symmetrical in relation to the center of the die and when it is desired to produce by means of the same die a series of similar designs, but inclined under a different angle to the vertical axis of the stretched fabric, the rack 9, Figs. 2 and 6, is pushed eitherbyhandorbymachinery-- say by a suitable lever-so as to impart motion to all the toothed wheels fat once, thereby also causing the dies forming part of the said Wheels to rotate with them. By such means the leaf e Fig. 2, maybe inclined at a variable angle in relation to the perpendicular, passing through the center of the die. The operation of the'dies e e may also be effected by means of one of the pinions g, Figs. 3 and 4, interposed between each pair of spur-wheels, upon which they are to act. Motion being thus imparted to the dies 6 6 ink is supplied to them in the manner explained above, whereupon the fabric L' is printed on, as described, its position being changed or not as occasion requires. When the printing is stopped, the arms 19 and p are turned back one into the eccentric shaft Q of each of the curved arms 0, (arm 19 carrying the printing mechanism and the other arm 19 the counter-dies.) The needles Y and their holders P are thus released, and the embroidering may be proceeded with in the ordinary way. The stitches that will thus be produced may be made exactly concordant with the printed design obtained before; or, conversely, the design may be first embroidered upon the fabric L, and a concordant printed design produced subsequently.

We claim- 1. The combination, with an embroideringmachine, of a printing attachment movable into or out of the path of the embroideringneedles, substantially as described.

2. The combination, with an embroideringmachine having the needles and supporting bar or rail therefor, of a printing attachment pivotally mounted on said bar or rail and adapted to swing down in front of the needles, and a co-operating pad for said printing attachment, substantially as described.

3. The combination,with an embroideringmachine having a series of needles and the supporting bar or rail therefor, of a printing attachment pivotally mounted on said bar or rail and having a number of independent dies corresponding in number to the number of needles and adapted to swing into or out of position with the dies in front of the needles, substantially as described.

4. The combination,with an embroideringmachine having a series of needles, of a printing attachmenthaving a series of rotatable dies movable into and out of the path of the needles, and mechanism, substantially as described, for simultaneously rotating said dies, as set forth.

5. The combination,with an embroideringmachine having a series of needles, of a printing attachment having a series of rotatable dies movable -into and out of the path of the needles, gear-Wheels on said dies, and a rack engaging all of said dies for rotating the same simultaneously to vary the angle of the pattern, substantially as described.

6. The combination,with an embroideringmachine having a series of needles and the bar A, of the support clamped to said bar, the arm 19, pivoted to said support and having the downwardly-projecting arm 1), and the series of dies mounted on said arm and adapted to rest in the path of the needles to print the fabric and to swing back out of the way to permit the needles to work, substantially as described.

7. In an embroidering and printing machine, the combination, with a printing mechanism comprising a series of circular dies movable about their centers corresponding in number to the number of needles Y in the embroidering frame or loom, the center of each die corresponding to an extension of each needle, and each die being embedded and held in the center of a toothed Wheel f, mounted on a shaft h, supported by one of the T-shaped bars Z, secured to the arm 19, pivoted in a standard or bracket g, which in its turn is attached to the ordinary horizontal bar A of the machine, of the series of needles and gearing connecting the toothed wheels on the dies with means for imparting motion thereto, substantially as described.

In testimony whereof we have hereto set our hands in the presence of the two sub scribing witnesses.
