PRESSER FOR FLIERS.

Patented July 14, 1914;.

Application filed April 7, 1914. Serial No. 830,101.

To all whom it may concern Be it known that 1, CHARLES T. BURLIN, a citizen of the United States, residing at iVhitinsville, in the county of Worcester and State of Massachusetts, have invented the following described Improvements 1n Pressers for Fliers.

The invention relates to an improved construction of the centrifugal pressers used on the fliers of roving frames, and provides a structure which can be produced at a less cost than heretofore, being otherwise the same in function and serviceability as the style of presser now in use. The new presser may be made entirely from a flat sheet metal blank, .in a few simple opera tions in suitable dies.

In the accompanying drawings: Figure 1 shows a flier such as used on roving frames and having a presser constructed in accord ance with this invention mounted on one of the legs thereof. Fig. 2 is'a cross-section of Fig. 1, online 22. Fig. 3 is a similar view, on line 33. Fig. 4 is a partial section through the lower bearing of the presser on the flier leg. Fig. 5 is a modlfled form of tang, illustrated as though a section on line 38 of Fig. 1; and Fig. 6 represents the flat blank from which the presser is formed.

The flier appearing in Fig. 1 may be of any suitable construction and forms no part of the present invention. It is illustrated as reinforced by the girdle ring 1 joining the extremities of its two legs to keep them from spreading. The leg 2 is hollow and slitted, as usual, so that the yarn may be introduced into the interior thereof and pass through the same to the tang of the presser in the usual way. For convenience of reference herein, the presser may be as: sumed to be composed of two parts, namely, a body and a tang portion, the body being the part that extends parallel with the flier leg 2 and is provided with upper and lower bearings thereon, and the tang portion being the horizontal part which carries the presser pad at its end.

According to this invention, the blank formed as in Fig. 6, is stamped or punched with holes or slots 3, 4 and 5, in substantially the arrangement shown. The hole 4: in the process of punching is drawn into a boss 6, of a suitable internal diameter to fit loosely over the end of the presser leg 2, as

shown in Fig. 4, and the hole 5 is countersunk and its edge rounded so as to provide a smooth passage for the yarn therethrough. The slot 3 is formed near the end of a lat eral arm 7 at the top of the blank and is of such width as will accommodate within it the lug 8 that has previously been punched out of .the wall forming the hollow flier leg 2. The length of this slot is suflicient to accommodate such range of oscillatory movement as may be required for the presser when finished. The lateral slotted extension 7 at the headof the blank is curled about an axis parallel to the main body of the presser and so as to surround the upper part of the flier leg 2, with the lug 8 thereon penetrating the slot 3, thereby forming the upper bearing for the presser. This bearing, as will be observed, also holds the presser longitudinally in position on the leg. The lower end of the sheet metal blank which contains the bossed bearing 4:, is bent transversely to the body of the presser, sub stantially at right angles thereto, so that it will embrace the end of the flier leg, as shown in Fig. 4, when the slot 3 of the up per bearing is engaged by the lug 8, and the tang 9 1s twisted so as to bring the entrance slit 10 in the yarn hole 5, on the upper side of the presser pad 11. a It is best to twist the tang in a direction which conforms to the direction in which the yarn is wrapped around it, so that thereby a smooth helical surface will be provided for the yarn to move upon toward the hole or eye in the pad. For this purpose the tang may be twisted a quarter or more turns, according as preferred, it being evident that the entrance slit 10 should be on the upper side of the pad and that the blank should be punched accordingly.

In Figs. land 3 the tang is shown as twisted. three-quarters of a revolution, whereas in Fig. 5, it is shown twist-ed but a quarter of a revolution, and it will be understood that its edges are in any event well rounded, so that it will provide a proper surface for the yarn to move on, irrespective of the number of turns the operative may wrap the latter upon it, or, indeed, the direction of such wrapping.

The body of the blank is folded one or several times on parallel lines, as indicated at 12 in Fig. 6, the folding preferably being done in alternate directions so as to provide a number of layers, 15, 14 and 16, asv

illustrated in Figs. 3 and 5, all these layers being compactly pressed together as shown,

and desirably curved slightly so as to project no more-than necessary from the; leg 2. It will be evident that the necessary clearance of the presser body from the leg is determined by the location of the bossed bear mg 6 in the lower bent over portion and by the olfset of the neck 17 at the top of the body. When the presser isinounted on the flier leg, the mass of the folded body is sufficient to counterbalance that of the pad and tang, so that the latter are pressed ina wardly' toward the bobbin, as the result of the centrifugal action. The proportions of the blank, as well; as the thickness of the metal, are adjusted-accordingly and obviousl y may. be designed to give any desired effect.v A larger or smaller number of folds may/be incorporated in the body, as desired, and the portion to be folded is desirably separated from the slotted part 7, by an open space 18, forming the neck-l7, and the said portion to be folded also terminates Copies ofth is patent may be obtained for five cents each, by addressing. the
