ADJUSTABLE FnIOrIoNAL' OL'AMPING DEVICE.

To all whom it may concern j Be it known that I, VTIIoMAs Lnvrs, a

citizen of the United States, residing in Chi`v cago, county of Cook, -andState of Illinois, have invented certain new and useful lmprovements in Adjustable Frictional Clamp` ing Devices, of which the following is a specification.` j j My invention relates to frictionalclamping devices, having todo particularly with adjustable clampingV devices, vmy invention being more `particularly useful in connection with model dress forms for yieldinglyholding them in adjustedv positions, an object of my invention being to provide a device of the character described which isvsimple of construction, cheap to manufacture and positive in its holding operation.

In the accompanying` drawing l. have illustrated embodiments of my invention in which, jj. w f

Figure 1 illustrates a skirt frame for dress forms embodying my invention; Fig. Q is a side elevation of Fig. 1 but showing only part of the skirt form; Fig. 3y is a top View of Fig. l being broken away at several points so as to present a more contracted gure; Fig. 4 is a sectionalong the-line'ff-t of Fig. 2; Fig. 5 is a section along the line 5-5 of Fig. 2, bothl Figs. 4. and 5 showing the holding device in a normal or locked position; Fig. 6 is a section similar to Fig. 5 but with the connecting strip drawn through the yielding clamping memberl in an unlocked position; and Fig. 7v is a modified form of the holding device of my invention.

Referring now more particularly to the detail constructionof myinvention as embodied in a skirt frame-I have shown a frame comprising four vertical sections 1, 2, 3 and 4, each section being laterally adjustable with relationA to the other sections. This matter of adjustment is, of course, old and my invention is directed more particularly to an improved holding device and I have applied such a holding device at each of the portions A, B, C and D. IThe parts to be joined are connected by means ofa rib bon-like member 5 which is suitably fixed to one section, preferably by means of rivets 6, said strip 5 then extending between relatively yielding members 7, 8 which are suitably secured to each otherrpreferably by means of rivets 9. The connecting strip 5 has a plurality of locking elements in the Patented .nuyea reis.

form of` indentations 10 -suitably disposed along the strip while the relatively yielding members 7. and 8 carry devices adapted to coperate with the holding indentations 10 of strip 5. These coperating devices comprise preferably a rivet member 1l which also serves to hold parts ofthe frame, and an indentation 8 in the bridge members 8, said elements 11 and 8 acting upon the concave `and convex sides respectively of locking elements 10. Y

In Figai l have shown the strip 8 in the act of being drawn through the yielding members, illustrating the manner in which the yielding members separate to allow adjusting movement thereof.

In F ig.V 7 I have illustrated another form of my invention in which the connecting strip 5 is provided with rectangular or clon# gated indentations V10 and correspondingly shaped holding devices'are provided in the relatively movable members 7, 8. By the useof the rectangularly shaped elements a more rigid holding means is provided, and

thus relative lateral movement of the connected parts is more nearly prevented. The rectangularly shaped indentations 10 in the strip 5 arefso constructedthat the projecting portion enters the rectangularly shaped indentation of the bridge element, and the rectangularly shaped indentation in the vertical 'strip 7 of Fig. 7 is adapted to enter the indented side of the movable strip. |lhus the connecting strip may be drawn through the opening made by the bridge and vertical strips under opposing tension thereof and yieldingly held in any one of a plurality of positions.

In operating the clamping device of my invention to secure different adjustment of the part or partswhich it connects the strip 5 is simply forced through the relatively movable yielding members 7, 8 said members 7 8 separating as in Fig. 6 so as to allow such movement of the strip 5 until the desired degree of adjustment is secured.

While I have embodied my invention in a skirt frame for model forms I contemplate applying it in other ways than that shown, the particular arrangement shown being simply for the purpose of`illustration.

It will also be apparent that many changes and modifications of the embodiments shown will readily suggest themselves and therefore I do not desire to be limited to the exact structure as shown and described but aim to cover all that which comes within the spirit and scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. An adjustable frictional clamping device comprising a pair of relatively yielding members suitably secured together so as to :form an opening between them, and a ribbon like connecting strip extending through said opening in contact with said members and having a plurality of holding elements whereby said strip may be drawn longitudinally through said opening in either direction while under holding tension of said members and yieldingly held by said elements in dilierent adjustments without lockinfr.

L 2). An adjustable connecting device comprising a mounting member, a yielding bridge member` suitably secured to the mounting so as to form a variable opening between them, a ribbon like connecting-strip extending through said opening in Contact with said members and adapted to be drawn therethrough in either direction while under holding tension of `the members, and cooperating means on said strip and members whereby said strip may be yieldingly held in any one of a plurality of connecting positions.

i, 3. A device of the character described Copies ofi this patent may be obtained for cured to the other device so as to form a variable opening through which said strip extends in holdingvcontact therewith, said strip thus being adapted to be drawn in either direction through the opening under .holding tension of the bridge member and ments positioned within said opening and.

carried by said bridge member and associated device, said strip extending through said Aopening and yieldingly held by `said elements whereby said strip may be drawn through the opening in either direction under holdin tension of theelements, and in-V dentations in said strip adapted to coperate with said elements whereby said strip is yieldingly held in adjustedps'itions.
