FLI'ER.

SPECIFICATIONforming part of Letters Patent No. 340,383, dated April 20, 1886. A pplicarion filed February 12, 1886. Serial No. 191,717. (No model.)

To @ZZ whom it. may con/cern:

Be it known that L JOHN A. V. SMITH, a citizen of the United States, residing at Man chester, in the county of Hillsborough and State ot New Hampshire, have invented cer tain new and useful Improvements in Fliers; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingr drawings, and to the letters and figures of refer`- ence marked thereon, which form a part of this specification.

This invention relates to fliers, the object of the improvement being to so construct a .flier as to obviate breakage in what has hitherto been considered the weak parts of the device; and the invention consists in providing the arms at those points where breakage commonly occurs with strengthening-pieces, as will be hereinafter fully set forth.

In the annexed drawings, illustrating my invention, Figure l is an elevation View of a iiier, showing theslit for the roving or thread. Fig. 2is a sectional View of the same, showing my improvement applied thereto; and Fig. 3 is a perspective of the bushing or strengthen` ing-piece.

Like letters of reference designate likeparts in all the figures.

A represents the upper shoulderpiece or nose, provided with a tubular section, B, and having angular and projecting sockets A A.

D represents the bottom piece, similarly provided with angular projecting sockets D D', and having a circular hole through which the spindle passes.

C Care the hollow tubular arms, bent in the form shown in the drawings. One end of each arm is inserted into a socket A of the shoulder-piece A, and the other end is inserted into a socket D of the bottom piece, D. The ends of the arms are firmly brazed into the sockets. One of the projecting sockets of the nose A is slitted to receive the roving or thread which comes through the tube B, and this slit intersects and merges into a slit, a, running lengthwise of the arm G, the latter slit terminating at a point, b, about midway of the arm, where the delivery-eye is located,

which servos to deliver the thread to the bobbin.

It is found in practice that steel tubular fliers of this general construction have a tendency to break at certain points, and do actually break in large numbers under the constant strain and motion to which they are subject. These weak points are principally near the junction of the arms with the upper and lower projections and the middley portion of the arms near the deliveryseye. The latter weakness, however, having been cured by means not herein claimed, will not be again referred to. There are obvious reasons for the breakingof the arms near the pieces A and D. In the process of brazing these top and bottom pieces to the steel arms by re or furnace heat, the steel arm is liable to be heated too hot for the quality of steel of which it is made, and it will therefore become weakened.

Further, after the brazing process is complete the brass that adheres to the arm must be removed by iiling, and this cannot be done practically without cutting the steel more or less, so that it will be liable to break in consequence; also, the breakage of the iiie'r at the bot-tom is much more frequent than at the top, because the flier is actuated from this end and the strain is very great, since the operator, desiring to change the position ofthe iers for dofng, lays hold of some one of them and turns the whole series together. Further, the constant stopping and starting ofthe frame for the piecing of broken ends, 81e., lays a much greater strain on the bottom than on the top end. The breaking of one flier generally results in the breaking of several others situ ated adjacent to it, for as it breaks it strikes the one next to it with sufficient force to shatter it also. l

It is my object and purposev in the present invention to overcome these disadvantages in 'the use of steel'fliers, and in so doing l lind it preferable to construct the arms of the flier from the bottom end to midway of the lower bend from a quarter to an eighth larger than has hitherto been customary, and from the enlarged portion I give them a gradual taper upward through the bend to where the diameter resumes its usuallength, which is maintained uniformly throughout the remainder of IOO the arm. This structural improvement, being but a preferable form in which to make the arm, may of' course be dispensed with, if desired, and the arms made of uniform 4diameter throughout. Therefore, in pursuance ot' my purpose, I provide a steel bushing or piece of steel tubing, E, which is placed within each end of the tubular arms at what are commonly called their "weaker points,7 and tirmlybrazed in position. The length of these bushings may be greater or less, as desired; but they are preferably made to extend from the end of the arm aboutl midway to the nearest bend, as shown in the drawings. As the lower ends of the arms are made larger than the upper ends, they wl/wtain a larger bushing, and consequentf7 oe strengthcned to a still greater degree. The bushings serve to give rigidity and strength to the arms, so that they will not break in ordinary usage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination. with the upper shoulder and the bottom piece of ailier, of tubular arms secured to said shoulder and bottom pieces, and bushings secured within the extremities of the arms for the purpose of strengthening them, substantially as described.

2. The combination of the upper shoulder having sockets for the arms, the bottom piece likewise having sockets for the arms, the connecting tubular arms having their lower eX- tremit-ies enlarged, and the interior strengthening-bushings for the arms, substantially as described.

3. The combination of the upper shoulderpiece, A, having sockets A A', bottom piece, D, having sockets D D', arms C C, whose extremities are secured within the sockets, and the bushings E, secured within the extremities of the arms, substantially as herein specied and shown.

In testimony whereof I ax my signature in presence of two witnesses.

JOHN A. V. SMITH.
