FLIER FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 745,400, dated December 1, 1903.

Application filed May 20, 1903. Serial No. 157,995. (No model) To all, whom, it may concern.-

Be it known that I, FRED SPENGE, a citizen of the United States, residing at Sanford, in

the county of York and State of Maine, have V invented an Improvement in Fliers for Spinning-Machines,of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to fliers for spinningmachines, and has for its object to provide a novel construction of flier which will run more evenly and with less vibration than the fliers as now commonly made. This object is attained by providing the flier with a steadying-weight which is rigidly secured thereto and situated axially thereof, and in the preferred embodiment of my invention the steadying-weight is placed at the upper end of the flier. ties that a flier thus constructed runs more steadily and with very much less vibration than the ordinary flier with the steadyingweight left off.

In many classes of spinning-machines the flier is carried by the spindle, and the speed at which the spindle can be rotated is determined to some extent by the vibrations of the flier, for if the speed of the spindle be increased beyond a certain amount the vibration of the flier as now ordinarily constructed becomes such as to render control of the bobbin drag very difflcult and uncertain. By applying the steadying-weight to the fliers, as will be hereinafter described, Ihave found that the fliers run so much smoother and steadier that it is possible to rotate the spindies at a considerably-increased speed with- I have demonstrated by pracsuch machine to illustrate the operation of my invention.

3 designates one of the spindles of any ordinary spinning-machine, on which is mounted in any suitable way a flier 4, having the usual arms 5.

6 designates the bobbin on the spindle, on which the yarn is wound and which will be given its traverse relative to the flier by any suitable mechanism. (Not shown.)

The roving or yarn being spun comes from the drawing-rolls 8 through the guide-eye 9 and thence is taken around one of the arms 5 and through the eye 10 at the end thereof, from whence it passes to the bobbin.

The parts thus far described are such as are found in all'spinning-machines, and their function and operation are well known to those skilled in the art.

My improvement consists in applying to the flier 4.- a steadying-weight l1, and in this embodiment of my invention said weight is applied to the head of the flier at the point where the flier is attached to the spindle. This weight may either be made in one integral piece with the flier or applied to the flier after the latter is made. In'either event the weight must be rigidly secured to the flier and so situated that its center of gravity lies in the axis of the flier. I prefer the conical construction of the weight shown in the drawings, as this does not interfere with the yarn passing between the guide-eye 9 and the arm 10 and also brings the center of gravity of the weightnearer the head. When the spindle is rapidly rotating, this weight, being situatedat the head of the flier and in the axial line thereof, serves to steady the flier and prevent vibration thereof, thus permitting the number of rotations of the spindle to be.

greatly increased. I have found from actual practice that with a flier constructed as hereinbefore described it is possible to rotate the spindle at five thousand six hundred revolutions per minute without causing sufficient jar or vibration in the flier to affect the drag of the bobbin.

In spinning the finer yarns it is very imcommon use it is not possible to run the spindle above about three thousand two hundred revolutions per minute without getting such a vibration in the flier and spindle as to destroy the even drag, and thus make the spinning operation very imperfect. With my improved flier, however, I have been able to speed the spindle up to about five thousand two hund red revolutions per minute without getting sufficient vibration to be noticed when one places his finger on the spindle, and consequently I can run the spindles at this extremely-high speed even when spinning the finer grade of yarns. Another advantage I get is that I can use a longer flier, thus increasing the possible traverse of the bobbin and permitting a longer bobbin to be used, for the steadying effect of the steadying-Weight is such as to hold a long flier from vibrating when running at normal speed.

While I have referred to my invention as being applied to a spinning-machine, I desire to state that it is equally applicable to a twisting-machine. I do not wish to be limited to a flier for spinning-machines, therefore, but intend the claims to cover any flier having the steadyingweight to whatever use said flier is put.

The precise form of the steadying-weight 11 and the way in which it is applied to the flier may be varied in many ways without departing from the principle of my invention.

I am aware that fliers have heretofore been made with a preponderance of weight at the head of the flier; but, so far as I am aware, it has never before been proposed to especially construct the flier with a steadying-weight at its head,which is applied to the flier especially to steady its action during very high speed of rotation, and therefore I intend to claim this idea broadly irrespective of the particular way in which the weight is applied.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. A flier for spindles having an axiallyplaced steadying-weight.

2. A flier for spindles having a steadyingweight rigidly secured thereto, and placed so that its center of gravity is in the axial line of the spindle.

3. A flier for spindles having a steadyingweight rigidly secured thereto at its head and situated in the axial line of the spindle.

4. A flier for spindles having two arms connected by a head, and a steadying-weight rigidly secured to the head.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRED SPENOE.
