HINGE MEMBER FOR BARRETTES'AND "THE'LI'KE,

Specification of Letters Patent. v

Application filed March 26, 1917. serial No.157g3jf4 and usefulHingel/Iember for Barrettes and the like,.of which the following isv a speci; ficationi 7 This invention relates to a hinge member for barrettes, and similar articles, a

The principal obj ects of the; invention are to provide a hinge member; which willbe capable of being used with a pin having integral projections at its ends sofas to avoid theuse of the common wire hinge pin and thus simplify the article itself and cheapen its construction and do. away with the possibility of the end, of the; metallic pin catching; in the hair; also.t0 provide an improved and simplifiedblankfor the production of the hinge members-for.- the pur: pose of decreasing the cost thereof. F urthe'r obj ectssandadvant'ages of" the invention will appear hereinafter.

Figure 1 is a rear elevation of a barrette showing a preferred form of this invention applied thereto;

Fig. :2 is an edge view of the same;

Fig. 3 is a sectional view on the line 33 of Fig. 2;

Fig. 4c is a sectional view on the line 44 of Fig. 1;

Fig. 5 is a bottom plan view of the hinge member before attachment to the barrette with the pin in position; and

Fig. 6 is a plan of ablank from which a plurality of these hinge members can be made.

The invention is shown as applied to a barrette B of conventional form having a pin P and a hinge member H. This pin is different from the ordinary pins because it has a pair of pivot lugs p integrally formed thereon. in the pressing operation by which it is adapted to be pivotally mounted on the barrette.

The hinge member is preferably made from a block, such as shown in Fig. 6, which shows a blank of celluloid having a series of longitudinal slots 10 extending all the way through it and twice as .many transverse slots 11 extending from one surface nearly to the opposite surface and equally spaced from the ends of the longitudinal slots. These transverse. slots extend through longitudinal slots-extend all the way through and; across. the transverse 3 slots centrally. The block, havingjbfienmade in this form,

iscut up intopieces along thedot-andedash I lines shown in the; figure, and. each one of these pieces constitutes a hinge member H The grooves] or slots 10 and 11: are unmodi; fied lnthe hinge member except that each one of the longitudinal slots lO'is bisected in cuttingthe block up, and. the surface shownin. Fig. 6 istheone that is cemented tothesurface of the barrette.

The cementing operation is performed after. the pin P is placedinposition from I the. back and movedinwardly until the pivot lugsp. come totheaendspf the short trans.-

verse slots. 11. The surface through. which the pin was movedis cemented to the back of. thefbarrette anditis found in practice that, the-cement runs down into the grooves 11' sufficiently to prevent; neci'proc ation of the pin in these slots 11 for anym'aterial distance but; the; pin is'prevented from stick- .ing' because there is such a leverage that it can be turned easily even after the cement has hardened or'it can be moved while it is hardening to prevent sticking.

Although the pin sticks out from the hinge member through the edge of the slot 10 that is cut in cutting up the blank it is impossible to remove the pin from the hinge member after the latter is once cemented in position. This groove or slot 10 is extended clear through the outer edge of the hinge member so that there will be perfect This is an important improve being performed entirely by hand, whereas now the introduction. of the pin is even' easier than it was before and the placing of the metal pivot pin is entirely eliminated. The doing away with the projectlon of the portant feature because they have been likely to catch in the hair and form an unfinished construction which detracts from 'pins from the hinge member is also an im- Y it as applied to a conventional barrette, I am well aware of" the fact that the invention can be carried out in other forms and can be applied to other hair ornaments than the one shown. Therefore, I do not wish to be limited in these respects, but what I do claim is V I 1. As an article of manufacture, abarrette having ahinge member cemented to the surface of the barrette and having a crossshaped groove therein extending from said cemented surface, the transverse portion of said groove stopping short of the opposite surface, and the longitudinal portion extending through it, and a pin having a lug on each side fitting in the transverse portion of said groove, the cement which unites theblock to the barrette extending into said groove to prevent reciprocation of the pin thereinr 2. As an article of manufacture, a hinge member of the character described consisting of a solid block having a transverse groove extending normally from its supporting surface, and alongitudinal groove crossing said transverse groove for receiving a hinge pin, the stock entirely closing the rear'end of the longitudinal groove.

.3. As an article'of manufacture, a hinge member of the character described having a transverse groove extending normally from its supportingsurface nearly to the Copies of this patent may be obtained for opposite surface, and a longitudinal groove crossing said. transverse groove and extending from one surface to the other for receiv ing a hinge pin. i 7

4. As an article of manufacture, a blank for a-series of hinge members consisting of a strip of celluloid or the like having a plurality of longitudinal slots extending entirely therethrough, and two transverseslots located across each longitudinal slot at equal distances from its ends andextending from one side of the blank nearly tothe'other side, whereby when said blank is cut up into pieces by cutting through between two.

slots and "also cutting through'the center of each longitudinal slot, twice as many blanks and extending from oneside of the blank nearly to the other side, whereby when said blank is cut up into pieces blanks will be produced having cross-shaped grooves for receiving the pivot ends of barrette pins."

In testimony whereof I have hereunto aflixed my signature.
