ADJUSTABLE CARDBOARD EASEL.

Application tiled December 22, 1921.. Serial No. 524,063.

To all whom t may concern -Be it known that l', MYRoN J. WHIPPLE, a citizen of the United States, and aV resident of Monroe, in the county of Monroe and State or' Michigan, have made an invention appertaining 'to Adjustable Cardboard Easels; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,.and tothe characters or' reference marked thereon,

which form apart of this specification.`

My invention has for its object to provide an easelv for the Support of articles such as advertising cards or figures made fromV cardboard, and wherein means is provided `for readily adjusting the easel as to theangular position in which it holds the object. It also has for its object to provide a means for locking the parts of the easel in its adjusted position. j i

The invention may be contained'in easels which in theirdetails may vary. To illus-l trate a practical application of the invention I have selected a cardboard easel containing the invention and shall describe it hereinafter. The easel selected is illustrated in the accompanying drawings. f

Figure l of 'the drawings is a `front view of the easel when ithas been'opened. -F ig. 2 illustrates the blank Yi'rom which the easel may be formed. Fig.' Sillustrates the means whereby the easel mayl be locked in its adjusted position.

l in the figures is a. blank having a ren tral portion 2 that is divided from the winged portions 3 by scored lines Ll, whereby the wings 8 may be readily bent along the scored lines L The lower ends, of the wings 3 are preferably inclined with respect to the lower end of the central portion 2,'and the upper corners of the wings 3 and the central portion 2 a-djoin. Moreover, the central portion is vpreferably rectangular in form and the wings are triangular. When, therefore, the' wings are bent,` at a slight angle to the central portion they form with the centraly portion a base that is defined by the lower edges of' the wings and of the central portion and a line joining the'outer lower corners Thus to increase the base area of the wings. or to increase the depth of theba'se as measured from the central portion, the wings may be bent with respect to the central por-k tionso as to form smaller angles with the central portion. AAlso if desired to vary the angle position of the central portion as meas ured in the plane of the central portion it may' be done, by moving one of the wings farther back to form a lesser angle with the central portion than the other of the Wings is placed. This is of advantage when a picture or ligure is secured to the central portionat a slight angle, which often occurs when kfigures or cards are secured to the easels byunskilled or careless individuals, and it is desired to correct the position of the card or gure when the easel is set up. ln the figure tilts to the right or to the left to lan undesired degree the easel may thus be adjusted to bring the ligure upright with reference to a transverse plane. TheA invention thus provides a ymeans for adjusting the easel both as to angles extending forward or back or as to angles extending right or v left. n j

'I have also provided a means for lockinfr the easel in its adjusted positions. A su stantially arcuate cut s made in the central part of the blank and across the central Vsition a portion of the edge may be provided withy a plurality of scallops. Preferably theuportions that are cut from the Wings are [provided with the scallops.l The sides of the sector are cut so that the scallops will `frictionally engage the .edges of the wings produced in the formation of the sector, that,` is, the scallops are substanf tially inthe line orl arc described by the corners 8 ofthe sector when the wings are moved angularly relative to the central porn tion 2 of the easel. The .edges of the wings formed by cutting the sector will frictionallyengage the scalloped portions of the sector, but the wings may be 'forced along the scalloped edges when some pressure is applied. One wingmayf be pushed fartherA just the angular position of the oblong cenwhen i trai portion 2 with reference to a transverse plane and both Wings may be adjusted to any desired position to adjust the oblong central portion oi the easel to any position with reference to any vertical plane extending at right angles to the central portion.

. lit desired,

means may be locking the planes to the sector in their adjusted positions. This may be done by the locking lips 9 that are formed from the Wings by cuts and a scored line" extending around the lips. The scored lines l0 `may entend substantially in line with the scored line fo' and cu il erally one olfk the cuts that surround the locking lips -9, such as the cuts ll, extend into the Wings so as to leave projecting portions l2 l/Vhen, 'thcreore the ivi s are to be an'. z-d, the sector 5 is bent rearwards on the scored line G and the Wings 8 are bent angularly relative to the central portion 2, While the sect r o is held so that its edges will pass between 'the projections 1?/ and the edges of the locking lips 9 formed bythe cuts 11, The elasticity of the sheet material will cause the locking lips 9 to rictionally engage the sector 5 and the lips and thev pro jcctions will hold the Wing in any position that they may be placed With reference to the sector, although'it vwill not hold it With the same rigidity that the scalloped edges Vwill hold it. lt, however, it is desired to "he Wings in their adjusted positions ag thecdge of the sectorit may be done orcing 'the lips 9 so that their surfaces be located in the planes of ythe =surfaces ,the n" es. To loch the Wings in adjusted' positions so that they cannot be moved therefrom Without destroying at least the ,edges of the sector or of thejivings in the vicinityof the sector the Wings may be placed between scallops otl the scalloped portion along the edge of the sector and the lips turned to locking positions', which' will tightlyengageithe edge of the sector.l
