Application filed September 7, 1920. Serial No. 408,557.

a flier ofnovel construction, which has the appearance of the standard drop forged flier now commonly used, and also has the desirable features of the latter, and possesses in addition advantageous features, as will be described, whereby a superior fliermay be provided at a minimum cost and in a mini- To this end the flier is provided with a solid metal member which forms one arm of the flier, and a hollow sheet metal member which forms the other arm of the flier and is firmly connected withthe solid metal mom her and reinforced by the latter to withstand the strain ofcentrifugal'force while in use. The flier is further provided with a hub of novel construction, for the reception of the s indle.

These and other features of this invention will be pointed out in the claims at the end of this specification. i

Referring to the drawings, or represents the solid metal member, I) the'hollow sheet metal member, 0 the hub, and d the key for engagingthe spindle (not shown) but with which the hub e cooperates in a manner well understood. The solid metal member a, shown separately in Fig. 8, is preferably forged from a steel rod'or bar andis shaped to form an arm having a substantially straight portion 10, preferably oval in cross section, and .a curved upper portion 12,

which latter is integral with a substantially flat center portion 13 forming asupporting member for the hub 0, and from which extends a shorter curved arm 14, of substantially the same curvature as the curved portion 12 and diametrically opposite thereto. The curved arm 1 1 is provided with a concaved outer surface 15 into which is fitted a correspondingly curved upper portion 16 of the hollow metal arm b, whose lower portion 17 is substantially straight and preferably round in cross section.

.The'hollow metal arm 6 is made from a flat blank or piece of sheet metal, preferably cold rolled steel, which is provided with smooth upper and lower surfaces free from scale, burs or the like.

The metal blank is curved at its upper endto conform to the curve of the shorter arm 14, and after being fitted to the arm li, is electrically welded or otherwise firmly secured to the arm 14. At the same time the sheet metal blank is welded to the shorter arm 14: of the solid member a, a lug 20 is also welded to the outer side of the blank at a suitable distance from the upper curved end thereof so as to cooperate with a lug 21 at the end of the shorter arm 14512-0 form a mounting for the usual presser employed .the blank in close proximity to eachother to form the hollow arm 5 and provide the latter with a longitudinally extended slot 25. The sheet metal blank is made of suitable shape and width to provide the hollow arm 6 with a larger or wider upper curved end portion, which decreases in size or diameter from its end 26 to the straight portlon 17 of said hollow arm. In the present instance, the hollow arm 6 is located wholly on one side of the center or supporting portion 13 of the solid arm a, and is provided with a finger 27 which projects beyond the open upper end 26 of the hollow arm and abuts against a shoulder 28 on the supporting portion 13 of the solid member, and is of substantially the thickness of said shoulder so as to have its upper surface substantially flush with the upper surface of the supporting portion 13, as shown in Fig. 1. While this construction may be preferred, it is-not desired to limit the invention in this respect.

After the hollow arm I) has been formed as described, the grooves or openings which are found between the hollow arm Z) and the side edges of the shorter arm 14 of the solid member a, may and preferably will be filled with hard solder or other suitable material, which filling 30 is represented in Figs. 6 and 7, and by means of said filling a smooth external surface for the hollow arm Z) and solid arm 14 may be obtained.

After the solid and hollow arms a, b have been welded or otherwise firmly secured together, a hole 31 is drilled in the supporting portion 13 at the center of the fiier, for the reception of the hub c, which is made from solid stock on a screw machine or automatic lathe and therefore rapidly produced. The hub c is provided with a cylindrical lower portion 33 whose external diameter is substantially the same as that of the opening 31, and with a head 34 of larger diameter which forms an annular shoulder 35 which rests upon the upper surface of the supporting portion 13 of the solid member a.

The hub 0 may be threaded into the opening and the threads rusted in or it may be electrically welded or otherwise firmly secur d to .the bearing member 13. The hub c is preferably provided with a tapering bore 37, which gradually tapers from the lower end of the hub to near the upper end thereof and with which communicates a smaller opening 38 in the upper end of the head 3% and a lateral opening 39, for the passage of the roving through the opening 38 into the head 34 and out therefrom through the lateral opening 89 into the hollow arm I), from which it passes out through the slot 25 at some portion of the length thereof in a manner well understood.

After the hub 0 has been fastened to the solid arm a, a hole or opening is broached or otherwise formed in the bearing portion 13 of the solid member a and in the hub c, for the reception of the key d, which engages a slot in the upper end of the spindle (not shown), so that the latter may drive the flier in a manner well understood.

The shorter arm 14 of the solid member a is preferably made of greater thickness adjacent the bearing portion 13 and tapers toward the center of said arm, as shown in Figs. 1, 3, 6 and 7, which increased thick ness acts to reinforce the curved upper portion of the hollow member so as to enable the hollow member to withstand the strain of centrifugal force at ordinary speeds of use, which usually ranges from 1000 to 14200 revolutions of the flier per minute.

The hollow sheet metal member Z) and the solid member a are properly proportioned so that in the finished flier, a perfect balance between the arms of the flier is obtained.

By welding the sheet metal blank to the solid member and welding the hub or lug 20 to the said blank before the latter is closed to form the hollow arm, any scale, burs or rough spots on the surface of the blank which ultimately forms the inner surface of the hollow arm, can be readily removed as such scale, etc., are freely accessible to the workman.

It is prefererd to make the hollow memher from cold rolled sheet steel as the latter is normally provided with a perfectly smooth surface. It is also prefererd to use hard solder to fill the joints between the hollow member 6 and the edges of the shorter arm 14 of the solid member, as the heat required to melt the hard solder is not sullicient to cause scale to be formed on the in ner or upper surface of the sheet metal blank, and if scale should be formed by application of too great a heat, it is accessible and can be readily removed, as above pointed out.

Furthermore, the hard solder can be quickly ground off and polished, and the joint rendered invisible by nickel plating. It is prefererd to nickel plate or othcrwi;-:c treat the finished flier so as to prevent rusting, due to the operators handling the fliers with moistened hands, especially in warm climates.

The finished flier represented in Fig. l and composed of a solid metal member and hollow sheet metal member has substantially the same appearance as the solid one piece flier now imported into this country, and therefore is not open to objection by the workmen who are usually foreigners and naturally would be prejudiced against fliers which differ radically in appearance and construction from those with which they are familiar.

Furthermore, the fiiers embodying this invention can be made in a minimum time and at a minimum expense, so that they can be provided in sufficient quantities and at such cost as to satisfy the demand for the same.

In the present instance a preferred construction of flier is shown, but it is not desired to limit the invention to the particular construction shown.

The supporting member 13 is preferably provided on its under surface on opposite sides of the center opening 31 with depressions or sockets 50 for the reception of molten metal which serves to secure the hub c to the supporting member and to strengthen the latter, especially so as to withstand the strains of centrifugal force.
