FLIER FOR ROVING-I VIACHINE S.

SPECIFICATION forming part of Letters Patent No. 595,996, dated December 21, 1897.

Application filed March 10, 1897. Serial No. 626,864. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. DUNN, a citizen of the United States, and a resident of Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Fliers for Roving-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to fliers for rovingframes, which consist, essentially, in a hollow boss which fits upon the spindle of the frame, a solid downwardly-depending leg, an opposite hollow leg, a presser-weighted finger pivoted to said hollow arm and provided with a shoe at the lower end. In use the roving from the rolls passes down through the said boss, then through the hollow arm and around the presser-finger, and through an eye in the shoe at the lower end of the presser-finger to the bobbin. The rail carrying the bobbin is, by suitable mechanism well known to those skilled in the art, made to traverse vertically. The flier with its presser-finger shoe, while rotating or having a circular motion, maintains the same vertical height. As each layer of roving is wound on the bobbin the traverse of the bobbin is shortened, so that each successive layer of roving is shorter than the preceding one, so that the finished bobbin will taper at each end.

The above description of flier is defective in that it is impossible to wind a perfect bobbin thereon, owing to the fact that the presserfinger is pivoted to a fixed point on the hollow arm of the flier, whereby the shoe in moving away from the bobbin travels in the arc of a circle instead of in a horizontal line, as it should. By thus moving or swinging in the arc of a circle the shoe does not maintain the same vertical height, which to a certain extent will counteract the effect of shortening thetraverse, making the bottom taper of the bobbin too obtuse, while the upper taper is too acute. Another serious defect or disadvantage is that when the flier is taken off or dotted the weighted end of the presser-finger will fall down and reverse the position of the finger, turning it upside down, so that it will require the use of both hands in doffing-one hand to take ofl the flier and the other to hold the presser in place.

The object of my invention is to provide an improved construction of flier whereby the presser-shoe will swing outward in a horizontal plane, and which will also retain its proper position when the flier is removed or taken off the spindle.

The invention consists in the novel c011- struction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a flier for a roving-machine constructed in accordance with myinvention, showing the same as it appears in use. Fig. 2 is a view of the flier removed from the frame. Fig. 3 is a detail view..

In the said drawings the reference-numeral 1 designates the spindle of a roving-frame,

and 2 the bobbin mounted thereon. I These may be of any ordinary or suitable construction and form no part of the present invention.

The numeral 3 designates the nose or boss of the flier, provided with the usual solid arm 4 and opposite hollow arm 5. This arm 5, near its lower end, is provided with two studs 6 and 7, one above the other, which form the pivots on which the presser-finger 8 swings. This presser-finger is provided with the usual weighted upper end 9 and with the pressershoe 10 at the lower end. At or near the center the presser-finger is formed with a slot 12, which may be vertical or inclined, with which the stud 6 engages, and above the same is provided with an extension 13, formed with an inclined or segmental slot 14, with which the stud 7 engages.

In operation when the presser-shoe is swung outward by the successive layers of the roving it will move outward in a horizontal plane, the inclined slot 14 and the stud causing the finger to gradually rise as the shoe moves, as seen by the dotted lines, Fig. 1, instead of moving in the arc of a circle, as in the case of the fliers before referred to. Again, the finger not'being fixed to its pivot its whole weight will be utilized in use, thus allowing it to be made much lighter.

studs near the ends thereof, of the presserfinger form ed with a slot with which the lower one of said studs engages and an inclined slot I 5 with which the upper stud engages, substantially as specified.

In testimony that I claim the foregoing as 1. In a flier of the character described, the combination with the hollow arm, of the my own I have hereunto aflixed my signature in presence of iJWO Witnesses.

resser-finger loosely pivoted thereto and vertically movable thereon, substantially as THOMAS F. DUNN.

Witnesses:

\Vhen the flieris removed, the slots and studs will limit the movement of the finger and prevent its turning upside down.

Having thus fully described my invention,

5 What I claim is 2. In a flier of the character described, the FRED A. RICH, combination with the hollow arm and the HENRY A. HIGH.
