FLIER 'FOR SPINNING MACHINES Filed Sept. 15, 1937 Patented June 7, 1938 FLIER FOR SPINNING MACHINES Harvey E. Herr, Bufialo, N. Y., assigno'r to Herr Manufacturing Company, Inc., Buffalo, N. Y., a corporation of New York p Application September 15, 1937, Serial No; 164,022

8- Claims.

This invention relates toc'ertain new and useful improvements in the fliers employed in connection with spinning machines and the like.

It has for its chief object to provide a flier structure having simple and effective means for preventing the flier overrunning or continuing to revolve after the bobbin has come to rest, thereby to prevent kinking or looping of the twisted yarn.

Another object of the invention is to provide a braking device for fliers which is simple and inexpensive in construction, which is designed for ready assemblage to the flier structure; and which is of minimum weight.

Other features of the invention reside in the r, construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing:-

Figure 1 is a fragmentary front view of a portion of a spinning machine showing the improved flier applied thereto. Figure 2 is an enlarged top plan of the flier and associated bobbin. Figure 3 is a bottom plan view of the flier. Figure 4 is an enlarged fragmentary vertical section taken in the plane of line 44, Figure 2. Figure 5 is an enlarged horizontal section of the hub and brake structure taken substantially in the plane of line 55, Figure 4. Figure 6 is a side elevation of the hub or sleeve of the flier body.

Similar characters of reference indicate corresponding parts throughout the several views.

The invention is applicable to spinning machines of any suitable and well known construction, Ill indicating the bobbin-spindle and H the 35 take-off bobbin mounted thereon. The thread or yarn from the bobbin extends upwardly through the eyes of the flier wires l2, 13 mounted on a holder or flier-body applied to the bobbin-spindle and thence upwardly through a guide or centering eye M to a take-up spool (not shown). The bobbin shown is of the type used with fliers of the eccentric type and has a recess IS in its top containing an inverted cup-like member it having an opening I! therein arranged concentric to the axis of the bobbin-spindle.

The flier-body preferably consists of an attaching sleeve, hub or barrel [8 made of fiber or like material and adapted to be fitted over the bobbin-spindle. At its lower end this sleeve has an eccentrically-shaped flange l9 adapted to be passed through the cup-opening l1 during the application and removal of the flier to and from the spindle. Spaced above the eccentric flange is a circular flange and fitted about a neck 2| rising from this flange and hearing or shouldered against the top side of the latter. is a base plate or spider 22 to which the flier wires I2, I3 are connected. The base plate has a depending tongue 23 adjacent its sleeve engaging opening which engages a companion notch 24 in the sleeve-flange 20 to lock the parts against relative rotation.

Extending about the sleeve-engaging opening of the base plate 22 is an outwardly-facing annular bead or flange 25" spaced from the topside of said plate to provide an annular groove 26' in which is disposed a locking ring 21. for operative engagement with the inner ends of the flier wires for securely retaining them in the customary. plate loops 28.

At its upper end the sleeve l8 terminates in an enlarged circular head or flange 29 and seated between the bottom face of this hea'd andrthe base plate flange 25 is a split ring'30" which'serves to effectually anchor the base plate to the sleeve. It will be noted that the upper flange 29 is of less diameter than that of the.lower flange 25 and slightly smaller than that of the base-plate opening, so that the base plate can be readily fltte to the sleeve I8.

The improved brake for preventing overrunning of the flier after the bobbin has come to rest is borne by the sleeve or hub N3 of the flier and preferably consists of a brake element 3| substantially in the form of a pin which is guided in an opening 32 formed radially in such sleeve through the bore thereof, and which is adapted for frictional or braking contact with the bobbin-spindle II]. This brake element is, by preference, disposed between the sleeve- flanges 20 and 29 and seated in an annular groove 33 between such flanges is a retaining spring 34 which extends over and bears against the head 35 of the brake element and constantly urges the latter into yieldable frictional contact with the bobbin spindle and resists outward displacement of such brake element from the sleeve. This retaining spring is made of spring wire and is substantially circular in shape, one end thereof terminating in an inwardly or radially-bent arm 36 which abuts edgewise against the bottom of the groove 33 to resist its turning relatively to the sleeve.

By this construction, the braking element constitutes an inherent part of the hub structure of the flier, and it does not disturb the balance factor of the flier nor add materially to its weight. Furthermore, the braking elements may be readily assembled and in the structural assembly of the other parts of the .flier the brake element 3| and its spring 34 are permitted the necessary freedom of movement required without interference with other parts of the flier-assembly.

braking means applied to said sleeve for engagement with the bobbin-spindle. I
