FLIER AND METHOD OF MAKING THE SAME.

Application filed june 24., 1922. Serial No. 570,648.

To all whom it may concern:

Be it known that I, HENRY SAHLIN, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massa- 5 chusetts, have invented an Improvement in Fliers nd Methods of Making the Same, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. I

This invention relates to fliers for use on roving and twisting machines of the character shown and described in United States Patent No. 1,393,356 dated October 11, 1921, wherein a hollow sheet metal member having a longitudinally extended slot is welded to a solid metalmember. I I I The present invention has for'its object to produce in a novel manner as will be described 21. less expensive flier of the character described. I II I I The particular features of this invention will be pointed out in the claims at the end of this specification. I I

Fig. 1 is a front elevation of a flier produced in a novel manner and embodying the invention.

Fig. 2, a side elevation of the hollow member shown in Fig. 1. I

Fig. 3, a plan of a solid metal or forged blank in its rough condition.

7 Fig. 4, a cross section of the forged blank taken on the line 4-4, Fig. 3.

Fig.5, a plan of the forged blank shown in 3 trimmed or cut to the shape desired. I

Fig. 6, a side elevation on a larger scale of the forged blank shown in Fig. 5 in its folded position.

Fig.7, a cross section of the forged blank in its partially closed position.

Fig. 8, a detail in'plan ofaportion of the sheet metal blank in juxtaposition to the end portion of the forged blank preparatory to I being welded thereto.

Fig. 9, a view like Fig. 8 with the parts welded togethen'and Fig. 10, a view like Fig. 9 with the weld smoothed and cleaned. The-flier herein represented comprises the essential elements of the flier shownin the patent referred to, in that it is provided with a solid metal member a having the substantially straight arm 10, the curved arm 12, the supporting member 13 for the hub o, the curved arm 14 extended from the supporting member 13, and a hollow sheet metal member b welded to the curved arm 14 and pro vided with a longitudinally extended slot 25.

The flier herein shown difi'ers from the flier shown in the patent referred to, in that in the present instance portions of the forged blank from which the curved arm 14 is formed and which were trimmed or cut oil in making the curved arm 14 shown in the patent, are in accordance with this invention utilized "for for'mingthe curved upper portionof the hollow arm, and for forming the upper art of the slot 25, and the straight portion or the hollow arm I) is formed from a sheet metal member which. is welded For otherwise firmly connected at itsupper end to the lower end of the curved arm 14 and is provided with a slot which forms the lower portion of the slot 25. I I

As a result, the slotted hollow arm 6 ofthe finished flier is a composite arm, in that it is composed of a hollow solid metal upper portion or member provided with a longitudi nally extended slot, and a sheet metal lower 1 portion or member provided with a longitudinally extended slot, which forms with the slot in the solid metal upper portion a continuous slot for the length of the hollow arm. In forming the composite hollow arm I), a solid metal blank is first forged into substantially the'shape shown in 3, so as to crudely form the hub-supporting member 13, a portion of the curved arm 12, the curved arm 14 having the longitudinally extended central groove 30 and the substantially wide side fins 31, 32. I I

In addition. the curved rm 14is provided I on its under sidewith a lug .33, indicated by dotted lines in Fig. 3. f

' The forged blank while hotis then cut or trimmed to provide the blank with the straight end 34, and to convert the fins 31, 32,'into tapering wings 35," 36 (see Fig. 5),

which are of suflicient width to enable them to be ultimately folded with the edges slightly separated and thus form the slotted tubular upper portion or member 37 of the hollow arm Z), which is shown separately in Fig. 6.

The wings 35, 36, while hot are first folded into the form of a U, as represented in Fig. 7, and its edges are squared on the line 38, and while in this form it has firmly secured to its lower or free end a U-shaped sheet metal member 39, which is formed from a flat metal blank, preferably of cold rolled sheet steel. The U-shaped sheet metal member 39 is arranged in juxtaposition to the end of the solid metal member 37 after the manner represented in Fig. 8, and is firmly united therewith by welding it thereto, the metal of the weld being represented by 40 in Fig. 9.

After the sheet metal member 39 has been welded to the solid metal member 37, the composite, partially folded hollow arm is then smoothed and polished on its inner and outer surfaces to remove the surplus metal oftheweld and also any scale, burrs and the like, and provide the hollow arm with a perfectly smooth and finished interior as represented in Fig. 10, after which the sides of the U-shaped composite metal arm are folded or closed in to -form the tubular hollow arm 7) shown in Figs. 1 and 2, and the longitudinally extended slot 25 therein.

The lug 33 on the solid metal upper member lat of the hollow arm is milled or cut to form the projections or ears 21, 20, which form the mounting for the usual presser arm not shown.

From the above description, it will be seen that by forming the hollow arm 6 of a solidmetal upper member orportion, and a sheet metal lower member or portion. a

, less expensive flier is produced, as the cost of filling in the joints between the sheet metal member I) and the curved arm 14 of the flier shown in the patent referred to, is avoided.

Furthermore, in thepresent case. the formation of scale on the interior of the hollow sheet metal member formed by the welding of the upper portion of the sheet metal member Z) of the patented flier to the curved arm 14 thereof, is avoided, as is also the scale due to the welding of the lower presser mounting lug or ear 20 to the sheet metal member, and as a result the necessity of sand bla-stin the inner side of the sheet metal member to remove this scale before polish- 12 of the solid metal member, which counterbalances the hollow composite metal arm or member may be integral with the blank shown in Fig. 3 or they may be welded thereto.

The hub-supporting member 13 is shown solid in Fig. 3, but it will be understood that it is suitably bored to receive the hub.

In the finished flier the joint between the sheet metal portion 39 and the solid metal portion 37 is obliterated in the polishing and finishing process and is practically not discernible, but for. convenience is indicated on the drawing in Figs. 1, 2 and 10, by the dotted line 45.

Claims:

1. In a flier,.in combination, a hub-supporting member, a hollow composite metal arm attached thereto and comprising a longitudinally slotted solid metal upper portion integral with the-hub-supporting memher and a longitudinally slotted lower sheet metal portion firmly connected with said solidupper portion with their slots in communication with each other, and a counterbalancing member for the composite hollow arm attached to the hub supporting member.

2. In a flier, in combination, a hollow composite metal arm having a longitudinally slotted solid metal upper portion and a longitudinally slotted sheet metal lower portion firmly connected with said solid metal upper portion with their slot-s communicating with each other. V

3. In a flier, in combination, ahollow composite metal arm having a longitudinally slotted solid metal upper portion provided with ears integral therewith and spaced apart to form a presser mounting, and a longitudinally slotted sheet metal lower portion having its upper end welded to the lower end of the solid metal upper portion with its slot forming an extension of the slot in said upper portion.

4. In a flier, a hollow metal arm having a solid metal upper portion tapering from its upper end toward its lower end and provided with a longitudinally extended slot, and having a sheet metal lower portion welded at its upper end to the lower end of said solid metal upper portion and provided with a longitudinally extended slot forming a continuation of the slot in said upper por tion.

5. The method of making fliers having a composite longitudinally slotted hollow metal arm, which consists in forging a hubsupporting memberwith an arm having substantially wide side fins, trimming the said fins to form tapering side wings, firmly securing a sheet metal member to the lower end of said arm, and folding the solid metal wings and the sheet metal member to form the composite hollowmetal arm and provide the same with a slot extended longitudinally in both members of said composite hollow arm.

6. The method of making fliers having a composite hollow metal arm, which consists in providing a solid metal arm with side wings, firmly securing a sheet metal member to said arm, and folding the solid metal side wings and said. sheet metal member to form the composite hollow metal arm and 10 to provide the same with a longitudinally extended slot.

In testimony whereof, I have signed my name to this specification.

HENRY SAHLIN.
