FLIER FOR SPINNING-MACHINES.

SPECIFICATIQN forming part of Letters Patent No. 356,336, dated J'anuary l8, 1887.

Application filed February 27, 1284. Serial No. 122,171. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. V. SMITH, of Manchester, county of Hillsborough, State of New Hampshire, have invented an Improvementin Fliers for Spinning-Hachinespf which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In that class of fliers having cast metal necks to receive the legs of the flier, and having a roving passage or throat produced by casting about a core, great difficulty is experienced from rough places, spots, or blowholes in the walls of the said passage or throat, upon which rough places the roving rubs and has its fibers caught. To obviate these rough places formed by casting, and which are he quently so deep that they cannot be removed by boring, and yet leave the neck in proper condition, I have provided the throat of the arm of the flier-neck with a lining, made as a tube inserted in the said throat, as will be described.

By way of differentiating my invention, I may here state that in the United States Letters Patent No. 227,015 the nose and neck of the flier has two projections, forming with it an inverted Y, and the flier-legs are driven into the diverging arms of this Y, and to this extent line it; but obviously it is impossible to extend the legs into a flier-head such as that herein shown and described, where the outlets from the nose and neck extend out sidewise and nearly horizontally from the nose, and are intersected at nearly right angles by the legs. Now, my invention resides in such a flier-neck, rather than broadly in applying a tube to a flier neck or nose.

Figure 1 shows a sufficient portion of the upper end of a flier to indicate my improvement, the flier-neck being partially broken out; and Fig. 2 represents the lining-tube removed.

The neck A of the flier, having the nose B, will be produced by casting, and by the employment of cores the said neck will be provided with the usual holes for the passage of the roving and for the reception of the upper end of the flier-legs O O, substantially as in United States Patent N 0. 110,617.

Referring to that patent, the so called throat is not lined, and if the casting condepth they cannot be economically removed and yet leave the neck of proper strength and weight.

To obviate rough places and present a very smooth surface at the interior of the throat, along and in contact with which the roving may pass from the usual central passage at the center of the nose B. into the opening made in the side of the neck for the reception of the flier-leg O, I have bored or reamed the neck from its outer side to the central opening or space, 2, of the nose, and the hole so bored having been made straight I drive or force into it a lining, b, preferably made as a steel tube. (Shown in Fig. 2, and in section, Fig. 1.) Then the said neck and tube are bored through in the line of the leg-receiving passage, and the hollow leg 0, preferably of steel, is inserted therein, and solder or brazing material having been applied, as usual, the neck and its parts described are subjected to the necessary heat to solder or braze the said lining and leg in place, as shown in the drawings, thus constituting a smooth surface of fine metal more or less polished, according to the extent of polish to which the lining is subjected.

tains rough places of any considerable size or The lining for what is denominated the neck is polished, to make the same very smooth, so that the roving cannot possibly find any rough spot upon which to catch.

After the parts have been soldered and brazed in place, as described, the leg is bored through in line with the lining, thus making a smooth passage for the roving from the neck into the leg, down which it is conducted to the usual presser. (Not shown.)

I claim-- The cast-metal neck A, constructed and arranged substantially as set forth, combined with the tubular metal lining b in such neck, and the flier-leg O, intersecting such neck and its lining at substantially right angles and opening into the said tubular lining, substantially as set forth.

In testimony whereof I havesigned my name to this specification in the presence of two sub- Witnesses:

FRED J. CRANY.
