SPECIFICATION forming part of Letters Patent No. 500,251, dated June 27, 1893.

Application filed October 29. 1892. Serial No. 450,385. (No model.)

T0 to whom it may concern:

Be it known that we, EMILE CoRNnLY and ROBERT CORNELY, residents of Paris, France, have invented new and useful Improvements in Embroiderin g and Sewing Machines, which E re fully set forth in the following specifica- This invention relates to embroidering machines of the type described in many prior patents, such as Nos. 228,445, 461,737, 466,889, 479,057, and particularly to machines of that type which are adapted to work cording-embroidery.

The principal object of the present invention is to provide means whereby the mechism which actuates the revolving thread-carrier can be instantaneously thrown into and out of action, so as to change from simple chain stitch to the cording embroidery, and vice versa, without arresting the operation of the machine. When machines of this character employ two needles, as in Patent N 0. 466,889 above referred to, making parallel lines of stitches, it is desirable to vary at times the distance between the two lines. Means for accomplishing this result are hereinafter described, so that by means of the presentimprovements we are able to produce, with the same machine, a great variety of efiects.

In the accompanying drawings, Figure I, is a side elevation of the parts of the machine above the bed plate (part of the casing being broken away). Figs. II and III are vertical sections of the looper-mechanism. Figs. IV and VI are details of the looper. Figs. V, VII and VIII are details of the removableeccentric sleeve, and Fig. IX shows a needle that may be used in place of the looper tubes.

In the cording embroidery machines, above referred to a pinion B on the main shaft A of the machine (Fig. 1) drives a series of pinions D, G, H, I, K, L and finally the sleeve M, on which the revolving thread carrier N is'secured.

In Fig. I means are shown whereby the actuating mechanism of the revolving thread carrier can be thrown into and out of action without arresting the work. To this end pinion B on the main shaft A of the machine is carried by a sleeve 19, and a pin 17 of shaft A passes through the slot 0 of sleeve 10 and thus the pinions B turn with the shaft A. The

lever E which turns on its fulcrum g is provided with a pin h which extends into the collar c" of sleeve p, and byturning said leverE the pinion is shifted on shaft A, and can be set in and out of gear to and from the pinion D while the shaft is turning; and consequently the entire series of transmission gear wheels D, G, H, I, K,L together with the revolving thread carrier N can be thrown in and out of gear during the operation of the machine, thus producing new and various effects in ornamental embroidery in which some of the lines can be made in single chain stitch embroidery, and others in cording work without stopping the machine.

The operation of the pinion B can be still more facilitated by the application of a lever O which turns on its fulcrum P and which is connected to the pin h by means of the connecting rod R; the handle of said lever is close to the hand of the operator which holds and guides the material.

WVhen the machine works with two needles, as shown and described in Letters-Patent No. 466,889, an. oscillating looper is employed which is operated by the oscillating motion of the screw shaft G (Figs. II and III) the latter acting upon the cylindrical part b of the looper P which is fitted into an eccentric hole of the screw shaft G.

By employing on the same machine needles of different distances one from the other, the throw of the eccentric in the screw shaft G must be shorter or longer according to the distance of said needles'one from the other. To effect this the hole in the gear shaft G is bored out in conformity with the widest distance which is employed between the two needles, 2'. 6., it has the throw of the greatest length as represented in Fig. III, and when the needles are set at a smaller distance one from the other a sleeve m (Figs. V, VII and VIII) which has a smaller eccentric is set into the eccentrical hole of the screw shaft G, as represented at Fig. II, and then a looper piece P provided with two small tubes '5, h at a small distance one from the other (Figs. II and VI) is adjusted into the eccentric sleeve m as represented at Fig. II. Thus a looper for any desired distance between the needles can be employed without any change in the construction of the machine.

Instead of the very small tubes h,i in Fig. the machine is in operation, substantially as 4 VI, small needles m (Fig. IX) can be employed described.
