EMIL OORNELY AND ROBERT OORNELY, OF PARIS, FRANCE.

EMBROIDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,147, dated June 11, 1889;

Application filed December 13, 1888. Serial No. 293,479. (No model.)

To all whom it may concern:

Be it known that we, EMIL CORNELY and ROBERT CORNELY, residents of Paris, in the Republic of France, have invented new. and useful Improvements in Embroidering-lVlachines,which are fullyset forth in the following specification.

This invention relates to sewing and mm broidering machines, such as described in Letters Patent No. 228,445, in which a rotatory thread-carrier is employed to wind a second thread around that which forms the stitches for the purpose of producing cordingwork, and has particular reference to machines of. this type in which a large bobbin or spool for supplying the winding-thread is mounted on the central tube of the machine.

In modifying the machine to employ a large spool or bobbin certain difficulties or objections are presented. When this spool is arranged to turn on the lower part of the nip ple-tube, it conceals the work from the operator to a considerable extent and cannot be easily detached for winding. Moreover, the devices for actuating the feed are so far above the cloth-plate as to render the action of the feed irregular and uncertain. When, on the other hand, the spool is arranged at the top of the central tube, its thread has to be carried down through said tube and through the nipple-tube. Consequently the nipple-tube had to be constructed to turn with the revolving thread-carrier, rendering it impossible to execute certain kinds of work.

The object of the present invention is to overcome these difliculties, which is accomplished by the means hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 is a front view of the head of the machine, partly in Vertical section, and the other figures are details of the several parts hereinafter described.

A is the needle-bar by which the needle B is carried, said needle-bar being secured to the tube D by means of a screw a. Tube D is reciprocated by the usual heart-slide. The nipple-tube is in two parts E E the nipple I) being secured to the lower part E in the usual manner. The parts E E of the nippletube are coupled together by means of the hook-shaped ends 0 d, Fig. 2, the two parts when coupled being held together by the needle-bar A, which passes through them and fills the entire space therein. The nippletube is operated by the slide F in the usual manner, the fork H of said slide entering the groove of collar g at the head of said tube, Figs. 1, 2, and 3.

Gr is a pinion to which therevolvin g threadcarrier C is attached, as in the patent aforesaid. Said pinion is supported within the annular flange I, which is part of the casting of the machine, and it receives motion from the main shaft through any suitable system of gearing. The hub of pinion G is perforated vertically, forming a passage h for the thread n, the latter being supplied by a large spool K, turning on the upper part E of the nippletube. The thread-guide holder L is secured to the hub of pinion G, and thread it is led through the guides 2 and 3 through opening '1' into thread-passage h, and thence to the eye of the revolving thread-carrier C; This arrangement permit-s spool K to be easily withdrawn from or placed in the machine for the purpose of renewing its thread. To accomplish this, the needle-bar A is withdrawn from the nipple-tube,when the upper part of the latter can readily be detach ed from the lower and from fork H of the slide F. It is evident that when this arrangement is employed, the thread a passing outside of the central tube, it is not necessary that the nipple-tube or nipple should revolve with the thread-carrier O, as is the case when the thread passes through the central tube.

Theimportance of having a non-rotating nipple-tube will be appreciated by consideration of the improvements described in Letters Patent No. 292,284, dated January 22, 1884; No. 311,644, dated February 3, 1888 No. 370,246, dated September 20, 1889, and No. 392,010, dated October 30, 1888. In Patents Nos. 311,644 and 370,246 arotating thread-carrier is employed for winding its thread around a cord and around the sewing-thread to fix the cord to the seam, as represented in Fig. 5

of the accompanying drawings. Since cord M passes .through the nipple-tube 'E and guide 4 of nipple b, the work performed by this machine could not be executed with a revolving nipple, which would carry cord M constantly around the needle B. In Patents Nos. 292,284 and 392,010 a revolving threadcarrier is employed in combination with two or more needles.

It is evident that several needles B B (see Fig. at of the accompanying drawings) working within a nipple I) could not be used if such nipple revolved with the thread-carrier, as in that case the needles would be in constant rotation with the nipple.

For executing the work performed by the machines above referred to, it isnecessary not only that the nipple-tube should not rotate with the th readcarrier, but also that it should be governed by the crank-handle of the feed mechanism in conformity with the direction of the feed. This result in the present machine is accomplished in the following manner: The movement of the crank-handle is transmitted by any kind of gearing to the pinions N, 0,1 Q,and R,whichlatte'r acts on tube D by means of a projection on its interior bearing on a flat face 5 of tube D, and a similar arrangement exists at C between the needle-bar A and a projection on the interior of tube E which latter is thus turned with the feed. The feed-actuating devices are carried by a separate shaft T. The conical sleeve IV, which actuates the fGG(l-l6V61,lS1G- ciprocated by slide X, while slide Y operates the feed-bar Z and feed-ring m. Slide F can sage for the thread from said spool to said tln'ead-carrier, substantially as described.

2. In a sewing and embroidering machine of the character described, a nipple-tube in two parts rigidly fastened together by a detachable connection, substantially as set forth.

3. The co1nbination,with stitch-forming devices and means for winding a second thread around the sewing-thread, of a nipple-tubc in two detachable parts, and a spool for supplying the winding-thread, said spool surrounding one part of said tube, substantially as described.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
