To all whom it may concern:

Be it known that I, LEWIS T. HOUGHTON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Sheet-Metal Flier-Frame, of which the following is a specification.

This invention relates to that class of fliers which are employed in roving-frames or for similar purposes.

The especial objects of this invention are to provide a strong, simple and efficient flier frame which may be stamped out of sheet metals; to provide improved means for counterbalancing the frame to insure the even running thereof; to provide a strong, simple and efficient joint for connecting the flier frame to its center piece; and to provide means for adjust-ably controlling the tension of the presser-foot.

Reference is to be had to the accompanying drawings which show one form in which this invention can be embodied, and in Which- Figure 1 is a side view partially in section of a spindle having a flier-frame constructed according to this invention applied thereto. Fig. 2 is a plan view of the same. Fig. 3 is a perspective View showing the clamps which journal the tube of the presserfoot upon one arm of the flier-frame. Fig. 4: is a perspective view of the top nut of a flier-frame. the center piece or bushing thereof. Fig. 6 is a fragmentary perspective view of a portion of the sheet metal body, and Fig. 7 is a perspective view of the end of the spindle. The flier frames which have heretofore been employed for making roving or for similar purposes have formerly been forged into shape by hand. That is to say, the usual practice in constructin a flier-frame has heretofore called for skil ed hand labor to forge the thread receiving tubular arms of the flier-frames, while in order to secure the perfect balance of such frames it has hereto-- fore been customary to grind the opposite sides of said frames so that a perfect balancing of the frames can only be secured after repeated tests.

One especial object of the present invention is to provide a flier-frame having abody portion which may be worked into shape from a sheet metal blank by means of dies and tools which will dispense with hand labor.

Fig. 5 is a perspective view of similar fragments of me al.

To counterbalance a flier-frame constructed according to this invention one or more counterbalancing Wei hts are employed which are located inside c %one of the tubular legs of the frame. Combined with the body portion of each fliei frame is a center piece or bushing, the ceni er piece and body portion being connected 3y a special joint which will reinforce and s .rengthen the body port-ion and hold the parts rigidly together. A presser-foot is carried it y a tube also preferably stamped from sheet metal, and the operation of the presserfoot may be controlled by a special regu ating attachment.

Referring to the accompanying drawings for a detail description oi a flier frame constructed according to his invention, as shown in Fig. 1, S designates a spindle loosely mounted on whic l, as indicated by dotted lines, is a large re :eiving spool. At its upper end, the spindle S is provided with a tapered section 10 for engaging the central bushing of the flier-frame, and with a key or top projection IL for locking the flier-frame to the spindle.

A flier-frame constructed according to this invention comprises a tubular centerpiece or bushing 13, and i. body portion 12. The centerpiece or bushi' 1g 13, as shown in Fig. 5, is provided with a transverse slot 14, and is counterbored and threaded as at 15. The/body portion 12 of a flier frame constructed according to this invention is formed from a sheetmenal blank which is shaped to form two at iular or partially tubular arms having a U-s haped cross section which are thereafter ben; or curved to the form shown. The larger or counterbalancing arm may be crimped or partially closed at its lower end to hold L counterbalancing weight 17 in place, and in practice, the counterbalance 17 is usualiy slightly under weight, the run countert alancing effect desired being obtained by dropping in small loose pieces, such for ex ample, as shot, or

As shown most clearly in Fig. 6, the body portion 12 of the flier-frame s cut out or milled transversely to for no two sets of bearing ledges 20 and 21. In fastening a sheet metal body portion 12 to a center piece 01' bushing 13, the body portion is set down ,into the slot 14, and the parts are secured together by'a top nut comprising a hexagonal top section 22, a1 overhanging section 23 which is preferal ly counterbored as shown in Fig. 1, and a threaded section 24. When the top nut is screwed down in place, as illustrated in Fig. 1, the lower end of the nut engages the bearing shoulders 21, while the overhanging section 23 of the nut enga es the shoulders 20.

n practice the top nuts are screwed down into place under considerable pressure, and the overhanging sections 23 are counterbored to insure bearings at the outside diameters of the nuts to secure the greatest leverage. J ournaled on the other leg of the sheet metal tubular frame 12 by means of

clamps

18 and 19, is a partially closed resser-foot tube 25. The

clamps

18 and 19 may be secured on to the presser-foot tube by fastening pieces or screws, as shown in Fig. 3, and the parts may be held up by a bottom-pin 27 as shown in Fig. 1.

In the use of a flier-frame as thus con structed the thread T passes down through the top nut along the tubular arm of the sheet metal frame 12, down through the presser-foot tube 25, and through the eye of a presser-foot 26. The weight of the presser foot 26 and that part of its support which is inside the axis on which the resser-foot support swings or turns is less than the weight of that portion of the tube 25 on the other side of the axis, so that when the flier frame is revolving at high speed, centrifugal force will tend to carry the presserfoot into engagement with the roving or yarn being wound on the spool this being the ordinary practice in the use of flierframes of this class. One objection to relying on centrifugal force alone to operate the resser-foot is due. to the fact that the action of the presser-foot would vary according to the speed at which the device is to be operated. This invention overcomes this defeet by providing a regulating attachment which can be set to different positions to vary the action of the presser-foot as desired. To accomplish this purpose, a small piece 28 is pivoted on the upper clamp 18 so that it may be swun or turned to different positions in which 1t may be fastened by small screws as shown. Extending up from the piece 28 is an arm 29 carrying a small wind-shield or blade 30.

When the wind-blade 30 is in the position illustrated by full lines, the air pressure acting thereon will increase the pressure of the presser-foot upon the spool, but by turning the wind-blade 30 to the position indicated by dotted lines, or so that the same is extended over to the other side of the flierframe arm, the wind pressure will tend to move the presser-foot away from the spool.

- By this regulating device centrifugal action may be more or less opposed or assisted as required to produce the desired presserfo'ot action according to the speed at which the device is to be operated.

I am aware that numerous changes may be made in my flier-frame without departing from the scope of my invention as expressed in the claims. I do not wish, therefore, to be limited to the particular constructions I have herein shown and described but What I do claim and desire to secure by Letters Patent of the United States is 1.
