4 Claims.
Thisinvention relates to hair curlers of the type employing a large diameter tube with members pivotally supported at one end of the tube forholding and clamping the hair on the tube. Stillmore particularly, the invention deals with a simple and economical method of producing curlers of the kind under consideration wherein means is provided for retaining the split portions Of'the tube in alinement and for preventing relative movement of the split ends of the tube in several directions, thereby preventing shifting and collapse of the tube, as would otherwise be experienced. The novel features of the invention will be best understood from the following descriptions when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts ar designated by suitable reference characters. in each of the views; and in which:
Fig. 1 is a side view of a curler with the parts in collapsedposition. v
Fig. 2 is an end view of thestructure as seen in. Fig. 1.
Fig. 3 is an enlarged sectional View through the tube of the curler withthe pivoted parts removed.
Fig. 4 is a partial section on the line 4-4 of Fig. 3,.on an enlarged scale.
Fig. 5 is an edge view of a sheet blank from which the tube is formed, part of the construction bein broken. away.
Fig. 6 is a planview of part of one end portion of the sheet,,as shown in Fig. 5.
Figs- 7 and 8' are views similar toFigs. 5 and 6, showing the first step in the formation of the tube.
Fig. 9 is aside edge view of the tube showing the next step in the formation thereof; and
Fig. 10 shows the method of shaping the tube arounda mandrel, the mandrel beingshown in section.
In the construction of curlers of the kind under consideration, it has been. customary to form the tubular body of the curler from a split tube, the ends of the tube being arranged in abutting engagement with each other. This typeof constructionhas been objectionable from the standpoint that the free abutting ends have been subjected to collapsing, as well as to relative long-itudinal shifting movement in the use of: the curler. It is the purpose ofv the inventionto so construct the tube of the curler as to reinforce as well as to key the abutting ends of the tube toretain said abutting, ends against relative movement in six different directions.
Considering Figs. 1. and'2,. I have here shown the assemblage, of. a. curler made according to the invention, in which ll represents the tubular body of the curler, l2 the hair end holding memher comprising a. U-shaped portion 13 pivoted to one end of the curler by the ends M of a curl holding yoke [.5 comprising a wire form. The cross head end [6 of the yoke is offset centrally, as seen at l1, and rotatable around the offset I1 is a rubber roller l8, preferably having a roughened surface I9. The ends [4, which form the pivot for the member I2 also pivot the yoke l5, and these ends within the tube II are offset, as seen at M, note Fig. 2, to retain the yoke l5 againstdisplacement.
The tube H preferably has a series of circumferential and longitudinally spaced perforations, as at 20, the member I2 having a plurality of similar longitudinal perforations 2i. In forming the tube II, we start with a preformed blank 22, the side edge portions 23 and 24 of which have arranged adjacent the ends of the resulting tube H, outwardly projecting lugs or fingers, as at 25-25 and 26-26, note Fig. 3. It will be apparent that the lugs or fingers, which may also be termed key elements, are arranged so that both elements 25-25 on the edge portion 23 are disposed inwardly of the elements 26-26 on the edge portion 24, so that when the tube is assembled, as later described, this arrangement of elements retains or keys the edge portions 23 and 24 against movement longitudinally one with respect to the other in either of two directions.
Continuing the formation of the tube from the blank sheet shown in. Figs. 5 and 6, the first step is to turn the elements 25-25 and 26-26 upwardly at right angles to the sheet, as shown in Figs. 7 and 8. Noting Fig. 3 of the drawing, it will be seen. that the elements 25-25 and 26-26. have converging side edges, as at 21-21 and 28-28 respectively. This construction facilitates the passing of the lugs one with respect to the other in shaping the sheet blank to the cylindrical form.
The next step in the operation is to bend the sheet centrally to form. a semi-circular central portion, as at. 29, note Fig. 9,. the side portions 23. and 24 being disposed. substantially parallel to-each other, and. the elements 25-26 being directedinwardly. The tube thus formed is then placed upon a concaved. surface 30 of a die 3|, after which a mandrel 32 is arranged within the sheet to seat: upon the half-round portion 29 thereof and then a punch 33 is. moved downwardly and its concaved surface 34 serves to first bend the ends 23 and 24 inwardly and to pass the elements 25 and 26 crosswise of each other, as partially seen in Fig. 10;
Upon'completing this operation, sufficient pressureis applied to that part of the tube having the elements 25-25" and 26-26 thereon, so as to force or spread the metal of the elements outwardly, as seen clearly at 35-35 on the elements 25-25 and. 36-36 on the elements 26-26 in Upon completion of the assemblage, it will appear that the elements 25-25' extend inwardly upon and rest snugly on inner surfaces of the edge portions 24, whereas the'elem'ents 26'26' correspondingly rest upon the edge 23. It will thus be seen that the elements 2525 prevent inward movement of the edge portion 24. The elements 26-26 prevent inward movement of the edge portion 23. In like manner, the elements 2626' prevent outward movement of the edge portion 24 and the elements 25-25 prevent outwardmovement of the edge portion 23. Reference to inward and outward, here is radially with respect to the axis of the tube and these four movements together with the horizontally checked movements and the pull apart movement provide the six checked movements referred to.
It will be understood that our invention is not necessarily limited to the specific arrangement or location of the lugs herein disclosed, and the number of lugs or elements employed may also be varied, depending entirely upon the length of the tubular structure which is produced. In this connection, it will beapparent that our invention is applicable to the keying and reinforcement of split ends of tubes of any type or kind, or in joining adjacent edge portions of products made from sheet material, particularly when it is desirable to positively retain abutting edges of the sheet against the different movements, as herein specified.
Having fully described our invention, what we claim as new and desire to secure by Letters Patent is:
