thin flexible character, which is bent into a I claims.

U-shaped bight, one leg of which is longer than the other and is adapted to be thrust into any convenient crevice or recess, or to be otherwise secured to a supporting structure, upon which the short arm of shellshaped bight bears with more or less pressure due to the inherent tension of the spring strip. This shorter leg of the bight is preferably provided with a claw like head having tines or spurs for engaging the display card or article. Any attempt to withdraw the supported card, display sheet or' article from beneath the claw or head tends to distort the bight of spring material increasing its pressure tension. For convenience in applying the device "and to retain it in condition for easy and quick application,

one leg of the yielding spring bight is slidingly engaged with the opposite leg by means of a keeper or arm, having therein a slot through which the longer leg of the bight is extended.

The object of the invention is to simpllfy the structure as well as the means and mode of operation of yielding spring clamp supports, whereby they will not only be cheap ened in construction, but will be more eflicient in use, positive in operation, durable, and unlikely to get out of repair.

A further object of the invention is to provide an adjustable yielding spring clamp support, the engaging tension of which will be materially increased by an attempt. to withdraw the'display card or supported article from beneath the support without first disengaging it from the supporting structure.

A further object of the invention is to provide an article of manufacture, which 1 will securely holddisplay cards and small articles of merchandise and which will read .ily accommodate "itself to varying thicknesses of such cards or articles, and which is readily adaptable to different conditions of use and to dilferent structures to which it may be applied. The purpose is to*provide such a spring clamp support which will be universal in its application to a wide range of purposes.

With the above primary and other incidental objects in View as will, more fully appear in the specification, the invention consists of the features of construction, the

parts and combinations thereof, and the mode of operation or their equivalents as hereinafter described and set forth in the Referring tothe accompanying drawings wherein 1s shown the preferred, but obviously not necessarily the only form of embodiment of the invention, Fig. 1 is a perspcctive view of a portion of a window or a display case to which the present spring pressure clamp has been applied for supporting a show card, the device and card being viewed from the rear. perspective view illustrating the application of the device to a barrel. Fig. 3 is an enlarged detail perspective view of the-spring clamp support, detached from the display card and supporting structure. Fig. 4 is a plan view illustrating the normal relation of the clamp to the abutment surface and display card.

Like parts are indicated by similar characters of reference throughout the several views.

Inerecting Window displays for advertis ing or other purposes, displaying show cards,

price tickets, or bulletins, it is frequently de' signedfto hold such matter pressed tightly against the glass of the window, or against theglass front or top of a show case. The pressure clamp is attached by thrusting one leg of the device into any convenient crevice in the window framing or between the walls or glass front and frame of the show case, beneath the hoop of'a barrel or cask, or beneath any convenient part or into any crack or crevice of the piece of machinery.

The pressure clamp support consists of a length 1, of flexible spring material similar in character to' commercial clock spring steel, which may be used'for clamp supports of Fig. 2 is a smaller size, but for those of larger size a spring st'eel (if somewhat greater thickness or increased tension is to be preferred. The length of spring material is bent upon itself ,to form a substantially U-sh z'iped bight 'Q,

one leg 3- of which is somewhat longer than the opposite leg 4. The short side of the bight 2 is slidably engaged with its longer leg 3 to form a noose, thus placing the strip of material under tension. The side otthe noose exerts lateral pressure against the abutment surface with whnihthe device is en gaged. The noose 'thus formed, carries a pluralityoi article engaging spur teeth 6 which may be either integral with the strip or attached thereto. The short leg 4 in the particular embodiment illustrated isEior'med 'a't' its extieniityinto ahead or claw 5,'prete'rably though not necessarily pro'vid ed with a number of small spurs or sharpened teeth 6, which engage a show card or other article to be supported and hold the same against slippage. The shorter leg 4: of the bightis reduced somewhat in width as it approaches the'head or claw 5, as is indicated at 7. Such re'ductionot'the width of the strip is "not essential. "It is, however, a matter of convenience and improves the appearance of the device, makes it less "bulky and distributes the tension or yielding-resistance of the clamp support in a inorcdesirable manner. The extended leg 3 of the clamp support is preferably sharpened somewhat at its extremity tofacilita'te its introduction into thdrab'bet of a Window frame beside the glass,'bencath a barrel hoop or into any other opening or be'neath any overhanging supporter ledge; To retain theclainp in its Lt-shaped form and in condition for instant application to a display card or article of merchandise, the short leg 4 of the bight is provided'with n arm o ke pe 8; ha insther'ein a slot 9, through which the longer leg 3 of the supportprojects. 'Io 'facilitate the sliding adjustment of the'keeper or arin 8 upon the longer leg '3 of'the device, the bearingside of the slot 9 is of arcuate form, whereby it is afforded only a limited bearing along a central line of the leg or strip.

In use the longer leg 3 of the clamp support is" thrust into a convenient'crevice as in the rabbet of the window frame beside'the glass or beneath the hoop of the barrel. This leg is thrustin such crevice in such relation that the claw or head 5 of the' dev-ice 'is turned toward and exerts its pressure in the direction of the window glass," show case rom ll? 0. h s e of the b'arrelj s th s m y be The di play ar orarti l to be suppo ted is n erpos d between the head or claw 5 and the glass of the window Q' f h w' I is eue hfheld in ts snipportedp tion by the spri g nsi n of he damp fi weven upo any att mpt o withdraw the card without first withdrawing the support itself will tend to flex or distort rial'posse ssing greater or less strength and tensionQaccor ding to the character and size of the display card or articlesof merchandis'e'to he supported. Itis to be understood that the article is of general application "and that tlie insta'nces of'usebefore inentioned are for illustrative purposes only, and not with any intent of prescribing the llSG and'application'of the'device'. l

From the above description it will be ap' parent that there is thus provided a device of the character described possessing the particular features ofadvantage s before onumerated as desirable, 'butwhich obviously is susceptible of rnodification' in its form,

proportions, detail construction and arrangenient of'parts without departing from the principleinvolv ed or sacrificing'an'y of its advantages. i

lVhile in order'to comply with the statute the inventionhas been'de'scribed in'language more or less specific to structural features, it is to be understood that the invention'is not limited to the specific details'showmbut that the means and construction herein discl'osed'comprises the preferred form of several modes of putting the invention into efiect and the inventiong is therefore, claimedin any of its forms or modifications within the legitimate and valid scope of the appended claims.
