Nits EMIL LAnsoiv, or NEvv YORK, 1v.` Y.

To all whom may concern.' l

Be itknown that I, Nils E MIL LARsoN, a citizen of the United States, and resident of the borough of Manhattan, in the county of VN ew York and State of New York, have invented certain new and useful Improvements in Glench Curtain-Clamps, of which the following is ka specification. Y.

The present invention, relates to improved means for suspending curtains, portieres, draperies and the like, and it has particular reference to,` and embodies, Vcertain novel features of construction disclosed in my previous Patents, Nos. 1,085,690v and 1,087 ,670,

but not claimable therein. For the sake of brevity, curtains only Vwill be mentioned hereinafter as the articleswherewiththe in-V vention is designed to be employed.

An important object of this invention -is to produce a curtainL suspending device of improved construction, so contrived that it will v` seize andy clasp the curtain without puncturing the same, and hold it fast from 11;; opposite sides as if by clenching, in pursuance kof the purposeimplied by the name clench-curtain-clamp under which the device herein ydescribed is :known in trade;

.A furtherobject is to providea curtain suspending. device of the type set forth having a air of jaws that are slightly diver-v gent vw enspaced apart to receive the cur-` tain, but will graduallypcloseand converge thereupon' ,at the outer ends whenbrought to f their'clampingposition; Y

j ready for use asa wholew at all times. i

4 is asimilar view,.looking from' the righthand sideofthe latter-named figure; .F1g. 5 is a transverse vsection of Fig. 3,

taken on Ythe line 5 5; i. f.

. ...Figx 6 is a transverse section of Fig. L2, i p

taken on the line 6 6; and n f Fig. 7 is a transversesection ofFig. il, taken on the line 7-7.

. *As shown in the said drawing-,the body j orprincipal portion of theclamp may conl sist ofa single strip of material preferably sheet-metal of a flexible and resilient charac?V ter, which strip is curved centrally to form avloop 11, and has itsopposite ends-12,.13, i

named. 'The ends 12, 13, constitute a pair.

of jaws or clasping Vmembers for the curtain, represented `by. dot-and-dash lines `at B., Fig. 6.

In orderto'secure lightness, strengthfand 1 ease, of movement along the pole'A, the loop 1.1* is made'conveXo-concave in a transverse direction,lthat is, convexoutward rand c'oncave' inward, and theedges thereof arefolded `over eXterio-rly,all as illustrated'inthe sectioned upper part of Fig. 4t.V It will-'fbe observed that the Vtransversal curvature, be-

sidesimparting steadinessI and rigiditywto theloop, causes itto'bear on the pole at the edges alone, `thereby. reducing-thel friction on accountof having pointcontact only with the pole, and the edges being 'overlapped` produce'` the requisite stiffness inthe sides of theclamp which ordinarily will be f subjected to' the 'greateststrains The aforesaid loop ends or clasping mem-` bers 12, 13, ralso have their opposite-lateral edges bent/,externally Lbut these edgesext'end in oppositev directions at. substantially right anglesto-the metal web; of whichthefsaid A membersare: formed, so as i-to constitute out# wardly-directed Lianges- 16, 17, `by .the sides of thesame.- a The-flanges here spoken yof serve 4tocounter'act the inherent pliability of thefweb, and 'further discharge other func# tions,nwhich .will hereinafter appear.l

Grippers of eone-and-socket formation 'are provided-on the clasping members 12, `13.1;0

afforda-lirmer hold on the curtain B inserted" therebetweenfwhen A'the kmembers farei I brought together in close contact, in the manner represented in Figs. 5 and 6. Such grippers, as seen in Figs. 2 and 6, comprise a conical protubei'ance or hollowhbuttonl 21 produced on the inner surface" of "one` of f the members, and a correspondingly-shaped oppositely rimmed aperture 22, forming'a socket therefor in the face of the other member directly opposite. may be used ask the length of the pair `ofvjaw's or clasping members 12, 13 will accommodate, the invention contemplating the use of f gether or apart, either to clamp or release the curtain, consist of a screw 25 and a nut 26 co-acting therewith. The stem `or shank of the screw 25 passes through alined apertures 27, formed in the webs of the opposite members 12, 13. A knurled head 2S is provsame may be located on the outer side of either member, for instance the member 13, as; shown. When the head 28 is thuspositioned, the nut 26 wil'l,-as=amatter of course, be placed on the outside of the opposite member 12, as seen inthe drawing. Both the head f and nut are confined, at least partly, between thetlanges k16, 1T, of their respective jaws or clasping members, -'-an`d they are further maintained in operative position relatively thereto each by la pair of retainers `'29, 30. iks illustrated,` these re` tainers lmay consist ofI lugs formed 'integral withV the flan-ges 16, v17, the lugs 29 engaging al peripheral vgroove "31 cut around the head 28, near the inner end thereof,fand-the lugs 30 vextending lovenopposite ysides of 'the nut26.

W'ith especial reference to Figs. 2 andY 3, it will benoted that-'thesaid'nut'26fis kept from being rotated withthevscrew-25,\due to its locationbetween the flang'l. Itis also madelonger in oner direction than it is wide being extendedy up toward thez vloopv 11. Inother words,the nutis tapped Vnearer to its lower endv to "provide-an eccentricallydisposedf threaded aperture for "the screw. Thispeculiar feature-of construction affords additional rigidity'to'fthe web of the clasp-l ing membery 12,-a-gainst-uvhich thev 'nutbears The l'latter may Vbe further Amaintained thereon, and ythe several `parts 'offtheffel'amp held together in permanent assemblage, *byV upsetting ftheend of; `the-screw, as :at i325 Fi-gs.-2, 3 and 17. This wilt reclude complete reti-ac.- tion ofthe screw? romzthenutfandfdisas- As many grippers .ing curtains of light fabric by turningl the lrn'urle'dhead 28 of the screw with the fingers, as f hereinbefore indicated. f However, the resistance met varies in natural ratio to the thickness ofthe-r material 4ventering.finto the composition of'the curtain, and therefore,to"pro\`fide for the convenient clamping of heavyfabrics, thescrewf head 28 is formed with Vatransverseopening 36, permitting the l insertionA ofa pin-wrench, which ymay be used to turnthe screw'w-hen'lthere iso'ccasion to tighten the jaws or clasping members 'upon curtains exceeding fthe "aver-age thickness.k f v n yNormally,the'spring of the loop 1-1 is'such as to causethe jaws or clasping members-12, lto move apartfrom'each other on slightly divergent lines, inv the best `posit-ion to' receive thecurtain betweenthem, lwhen the screw ,has been retracted to its full :limit v through'thenut 426, aseXe-mplified bythe reverse conditions depicte'din Figs. 2and7. Butthis di'vergentp'osture of the opposed members 12,13 is not favorable to the `retention3of the suspended curtai-mand it would remain unaltered and ineffective iffthe members were allowedtofpress directly'against each other-at-the ends thereof "nearest-fthe loop, owing to the location ofthe actuating screw. Therefore, to I overcome' the *divergence; the inner ends lof' the clasping members are :provided with opposed,*inwardly facing vbosses v39, 40, which abut against one anotherand operate atoj keep" the said inner ends out of? fact-ual contact` with each other;

n This expedient prevents `theo'uter "ends: pof

the blasping members ffrom. Jopening `for spreading apart whenvthe'screw Vistightened. Itfaids in hold-ing lthe 'goods orl curtain between the-jaivs'more secure, since the bosses 39, 40, constitute -fulcra upon 'which ithe clasping members oscilla'te underpressure'of the screwdand are `'forced actuallyj to convergeV toward each other attheir outer ends,

between which the -lcurtainis firmly grasped. Thesev bosses aref located Y at the greatest, `possible distance apart Vtransi'verse'ly 1of Vtheir-` respective l, clasping '1nenrbers, and :preferably atthe lpoints l-vvhereythe lapped-over edges the ends of said loop, tightening means .for drawing said jaws together, and inwardly facing bosses located near the juncture of said edges with the jaws preventing the outer portions of the latter from spreading when said means are tightened.

2. A curtain clamp comprising a suspending element, laterally hanged clasping membetween the flanges of one of said clasping members, anda screw located between the flanges of the opposite member engaging said nut. 1

4. A curtain clamp comprising a suspending loop with the eXtremities thereof bent outwardly to form a pair of clasping members, and tightening means for the latter consisting of a nut and screw, said screw being upset at the end over said nut eXternally of one of the clasping members, and provided with a head capable of pressing against the other clasping member on they outer side of the same. v

5. A curtain clamp of resilient material comprising a suspending loop with clasping members depending therefrom, a stop at the juncture of said loop with said members, and tightening means intermediate of said stop and the outer ends of the clasping" members causing said ends to approach each other. Y

V6. A curtain clamp comprising a suspend-4 ing element, clasping members depending normally on divergentlines' therefrom, opposed vstops located near the juncture of said element with said members, and a screw and nut tightener intermediate said stops and the outer ends of the members acting to `draw the latter together.

7. A curtain clamp comprising a suspend-j ing element, clasping members depending therefrom provided with externally directed flanges, an eccentrically tapped nut arranged to bear upon one of said members between the flanges thereof, and a screw in engagement with said nut having itsV head opposite* positioned to press against the clasping member. f

8. A curtain clamp comprisingv a suspending element, clasping members depending therefrom, tightening means for the latter` consisting of a screw, and nut operable onv opposite sides thereof, and-retainers acting to confine the tightening means in juxtaposition to their respective members.
