UNITED STATES LILLIAN K. ENGLE, OF LANSDOWNE, BENNSYLVANIA FASTENING- .A ND- SUQBOBI EING DEVICE.

Application tiled Qctober- 11-. .1927, serialno. 225,583.

My invention relates to. a new and. useful taste-h ng and suppor ng ".dev Qe an mo pa icul rly to de i o hi h efi e hich an e firmly and deteqhe ly ec e to fasten and support diflferent objects to each other'lor to a suppor t withoutithe'ei'd of an y external or auxiliary eans.-

My invention further relates to a fasteningand supporting device which maybe employed in the vertical horizontal or pendant positiomthat is,'one which is adaptedto resi st lateral, downward'and upward. strain or ull. i I p My invention further relates to. a novel device of this character wher ein the'piercing o a e ng. ele nt are int with th supporting or retaining element, the entire device being madeof suitable sheetmetal or the like, by a singlestamping, punching or casting operation.

'110 the above ends, my, invention consists of a double .hook, piercing arms or, prongs on either side of said hook, a base common to said hook and said prongs and forming a right angle therewithflnd a pair ofdoubled piercing arms integral with and extending from either encl'of'the'opposite edgeof said base in parallelism. therewith, said" prongs and doubled arms beingprovided with novel means for interlocking with the fabric or other material, said elements being also provided with bottom grooves forming stiffeningribs.

M'y'invention further consists in so'constructingthe Hiercing arms and i'prongs above referred 'to, aslto afford a firm, detachable engagement with the object beingjfastened or supported, and to-reduceithe holes orperforations made bysaid prongs arms'to a minimum.

My invention further consists in providing the prongs and base above referred'toiwi-th" reinforcing ribs to adapt my novel device 'for heavy. duty without materially increasing the weightor dimensions th reof: 7

My invention further consists in various other features of' construction andfcollofca- .tion of parts as hereinafter described. 7

For the purpose of il lustrating my invention, I' have shown in the, accompanying drawings, forms thereof which are "a'tfp'res ent. pre

e ed as e thgy v ls re i111 practice, satisfactory and reliable results, although it is to beunderstood that the various instrumentalitiesof which my invention con sists canbc variously arranged and organized and that my invention is not limited to the 'precise arrangement and organization. of

device shown detached.

F i g. 3 represents a bottom view of the same.

Fig. 4 represents an end view of the same.

Fig, 5 represents a section on line 5 50f Fig. 2. j I

Fig, 6 representsa plan view of a modified construction embodyingmy invention. Fig. 7 represents an end view of a further modified form embodying my invention.

Referring to the drawings, in. which like reference characters indicate like parts, 1 designates a fastening andflsupporting .device embodying my invention comprising the relatively long, slightly co-nverging,.pointed, tapering prongs 2, the relatively, short, pointed, oppositely disposed, doubled arms3, and; the intermediate, lntegral base or connecting body portion 4., From the base Land integral there'with,jextends the arm or tongue '5 having the humped; portion 6', said aim being bent back upon itself to form the hook and lie/mg continued rearwardlyto, form. the arm'8 whichis similarly humpedas at 9, the humps 6and-9'on the arms 5and' 8 respectiueiy forming a lock or closure for the 'doubledhook. or re ta'ining. member 7', as will ej nd s eed f om F gs 3; 4' and The tapering, piercing prongs 2 -a-nd 3 are provided with the recessed portions-l0 which serve to interlock with the Weave or warp and weft of'a, textile fabric such as a curwin or other material into which they. may be inserted. Another advantage of the, re.- c'essed portions 101is that'wlienthe material is initially pierced'by the prongs 2;.and arms 3', a hole or opening is made, "liar ie enough to permit of: thepassage ofthe'widest portio 11 of said prongs and arms, and if the material is permanently thus distended, when the prongs and arms are withdrawn, a relatively large hole or opening remains, since the warp and weft of the material having been widely parted over a long period of time, fail to resume their normal positions, due to the loss of elasticity. By providingthierece'ssed por tions 10, however, the fabric, and particularly the warp and weft of the fabricfnot having lost their inherent elasticity, will tend to resume their normal positions around the, recessed portions 10 and-being thus not widely parted or distended, only a small hole will remain after-the prongs and arms are Withdrawn from the fabric.

Thebase 4, the prongs 2Iandthe armsB,

with respect to the curtain 1 3 is-possible,

since any tensi'on,'such as the weight of the curtain 13, exertedv on the. device, merely serves further-to strengthen theengagement of the; prongs and arms 2 and 3 with; the body of the fcurtain, the book -7 being in turn prevented from being detached or object, either by its position as inllig. 1, or by the contaotir g locking humps or knobs 6 and 9.

In F 6 I have shown a modified form ',of my invention wherein the prongs, 2 are relatively thin throughout their entire length and are provided with the swelled or enlarged portions 15 which fservle to interlock with the elastic, contracting warp and weft of the fabric to prevent slipping. In this construction also, only a small, practically invisible hole remains afterthe prong iswithdrawn, since the cloth or fabric 'is I only temporarilydistended ,or parted wide enough to permit of the passage pf the'en-, 'larged portion 15, after which the warp and weft. adjust" themselvesaround the relatively thin; portions 1 6 of th'e-prongs2,

InQFig. 7 I have shown a further modi fied construction, wherein the prongs ,2, ,of the modified-construction shown in Fi 1 and-6,are.corrugated orwaved asat 'l to afford a .firiner. engagementv of the prongs with the fabric if. so desired.

It will thus "be seen thatQIhave devised a novel fastening and supporting device which iscompact, neat andserviceable, and

curtain rod not working loose from the ring '14 ordother ,comprising a doubledho ok, parallehpiercone which can be manufactured. economically by a single stamping or punching operation. It will also be seen that my novelfastener can be secured to a fabric or similari; inaterial without the use of stitches.

of which are at present preferred by me since they will give-1n practice satisfactory and reliable results, it isto be understood that such forms can be varied without departing from, the scopeofmy invention or sacrificingany, of itsadvantages.

Having thus described my invention, what I claim as newand, desire to secure by LettersjPatent is; l I
