GLAMPING BAND.

Application filed September 16, 1924 Serial No. 738,104. a

To all whom it may concern:

Be. it known that I, JEAN PAUL MARIE MALLEVILLE, a citizenof France, and a resident of 142 Avenue de Versailles, Paris,

France, have invented some new and useful Improvements in a Clamping Band, of which the following is the specification.

This invention relates to clamping bands or universal clips consisting of a strip of metal, th tension of which is obtained by coiling the said strip round a pin, roller, or a similar part.

Generally the part ofthe clip employed for the purpose of stretching the strip, often projects to such an extent as to constitute a serious inconvenience, for instance in the case of hose-pipes used for watering purposes. I

The assembly of parts employed for stretching the strip constitutes the most expensive part of the clip, and is used only for maintaining tension, once the latter has been effected.

The purpose of this invention is to provide means for removing from the strip the as sembly of tightening parts, once the stretching operation has been carried out, and to render the said parts available for putting another clip under tension.

The strip then remains tightened without the assistance of any tightening parts. These parts can, however, be left where they are fitted or fitted on again" after having been withdrawn, as required, if it is desired to increase the tension originally produced. Broadly, according to the present invention, in clamping bands of the nature set forth, there is employed a stripof metal with a slotted or shackledend anda free end, and detachable tightening means to grip the free end, put 'itund'er'tension, and bend it over the slotted end. I

' On the drawingattached hereto, and to which reference is made,"several forms of execution of the subject-matter of this present invention are shown'by way of examples. Figure 1 shows a fitting of standardtype employed as a part for "connecting thetwo ends of the strip L0 be tightened.

ingelement. I I g In accordance with this present invention as shown in Figures 17, and if use be'imade of ametal strip 1 of uniform width'and indefinite length, one of the ends of the strip is clamped'to a shacklev or fitting 2 provided with anopening, and of quadrangular form, which is emplo ed as apartfor connecting the two ends o the strip.. I

This fitting, provided with an opening, has projections orstops 3, which act as supports for the stretchingfdevice. v

This device is detachable andconsistsof a pin 4 on which the strip is to be coiled, and a support 5 on which rests the pin or spindle whilst the strip isbeing coiled round the said pin. This spindle 4is provided with a slot 4 inside which is clamped the free end of the strip, and with a head 6 witha -hole 7 for the purpose of holding a tommyor asimilar part employed for workingthe pin in the required direction.

WVhilst the pin 4 is thusbeing rotated, the

strip slides under the support 5jWhflGh is inserted between the said pin and the stops of the fitting provided with an opening, and the said support is held by the pressure of the pin in the groove 5 the edge 8 of the support engaging with the stops 3, which provide the said support with points of bearing.

Thebottom' part of the support is, moreover, provid'edwith a projection 9 in which is made a slot 9 through which passes the strip prior to its doei-ng wound round-the pin, whilst in the upper part of the said support is made a hole 10 in which fits"a ro'd-f B, the purpose of which is to hold the support whilst the pin isbeing-rotate'dz The strip is coiled up once or twice, ac-

' cording tof the tightaifig to be obtained Figure-3)".-

If use isinadeof meantim coiling device shownby Figure 2, I it willl be observed 1 that these-rip is "clamped tothe shackle 2', that the said stripis wound round the 'arti'cle to be "held (wlii'ch-isnot shown) and passes through the inner peiiing of the said shackle, whereafter 1t is wound round the v first coilffp asses through opening '9 and lastly co'ile'd ioimcrpia dz In thi s" rrange ment the strip isw wound and tightened by rotation, in the direction shown the 'arrow of the inwhich rests a ainst thesuo- V a P a a 1 port, which is -h '1d, in its turn," by tl'i e 'rodB.

The"support then rotates-round its points of bearing at 3, 3, andthe strip becomes clamped and'finterlockd by bending round the bar of thesha'ckle r The tightefiingepeiatieahaving thusbeen carried out and fiiiishied o'n the? article to be fined, the tension producing partsf'Kpin'aiid strip tightened, eitlir with a view to'ide su port} maybs le ft in-tlie posit-ion which respeetiyelyoccupy an 'tlie st-rip (Shawn ddtted lines); as stated in-the *opening raphs As it mayuiewevefybe use-1 ful" to"'r"em veuiesepaas'winise1 epingjthe' creasingthespacepeeupiedf orwitli a view to making use of tlie'saild parts for the pina 'st p. as

The fitting may also consist (Figure 10) of a rectangular end 11 for the same purposes as the stops 3, provided with a slot 11 through which the strip is fitted for the last operation. In" -'ac'cor :lance"with"a "further alternative mode ofexecution, this fitting may be given the shape shown by Figure 11, with lateral projections 12 providing the support with points of hearing as with the projecti'on's'3, 3, in Figures l7, and with a central tongue 18, for the purpose of holding the end ofithe strip iatter the tightening operation, and after removal of the tension producing parts?- Figure 12 shows a mod 'e ofeXecutioii-of this kin'df in" which the end of the "strip is kept held-"against the 'artiele; secured, then brought back helowthe tbngae 13, with a "View" to" preventing "the said strip fronr be ing accidentally turned up again:- I
