APPARATUS non Ascnn'mmme coLons.

Application filed July 28, 1926, Serial No. 125,067, and in Germany July 2 9, 1925. This invention relates to an'apparatus for instance 7, 8,, etc., so that each can be ascertaining colors, which is characterized quickly and easily found when .desired/ by the fact, that upon each of the cards of 1 The fulcrum point for the several cards 50 celluloid, fan-like arranged around a comis formed in the known manner by a. pin 12,

5 mon turning point, rectangular openings are passed through a central opening.

disposed both in radial direction and in In the fan, constructed as above described, concentric rings, besides of which openings the gradations appertaining to one special differently shaded oil specimens of colors color "are found once by progressing along 55 are fixed, which permit by glancing through a concentric zone, secondly by progressing 1 0 them an immediate comparison with'the obin a radial direction and thirdly by pursuserved object. I ing the gradation of one special color from The reading of the specimen of 'color is card to card; the gradations appear through given by the number .of the 'fan-segment the openings when small rotations take 00 and secondly by the location of the color place. This apparatus permitsnot only a upon this fan-segment. close combination of numerous specimens in In the drawing the new apparatus is their relationship, but also the possibility of shown in a front view (Fig. 1) and in a quickly finding the desired color of cornside view (Fig.2) of theclosed apparatus parison, because all 'the colors, which are 05 and in a front view (Fig, 3) of the opened approximately similar to the desired color fan. are located immediately besides each other In the represented form of execution the 'upon one fan-card and in a corresponding apparatus contains five, segmental cards of ring of one of the neighboring cards. celluloid or of any other convenient mate- Besides these advantages, offered by the 70 rial; these cards are designated by the numnew fan in comparison'with prior forms of bers 1-5. Each of these cards contains a execution, as color steps for instance, the

number of rectangular openings 6, on both connection of all cards in one point around sides of which are fixed specimens 6 of whichthey are rotatable, the facilities of colors, for instance upon the first card 1 manipulation are raisedin a high degree. 75 yellow specimens shaded off till brown Finally the readily'flexible fan. can readily specimens; upon the second card 2 orange be pu' on the objects. I

specimens shaded off till brown specimens The new model permits a hasty glance and so on. This shading off of the colors over approximately 200 colors, when 7 -8 takes place not only in the circumferential fan-cards are applied and each fan-card is so direction but in the radial direction of the 24 by 39 cm., and when the specimen of rings a, b, a formed by the succeeding colors are 2,5 cm; high and not less than 1 openings and specimens of colors. On the cm. width. If the specimens have half the other hand the colors are shaded off from indicated dimensions and if they are doubly card to card. pasted, 400 colors can be looked over. s5 The first card possesses a centrally located I The new model is first of all thought for 4 opening 7 which permits inspection of all the color standards wllhelm Ostwald. the colors of the different cards, whereas But they can also be applied for the compareach of the other cards shows an opening ing determination of any other niaterials 8, 9, 10, 11, just beneath the opening 7 of (woven materials, minerals, metals, glass). or 90 the first card 1. This latter opening perany other objects, as thecase may be, when mits inspection of only the special-colors these objects are in a qualitative relationof the

cards

2, 3, 4 and 5. Thenumbers of ship with numerous similar materials or the different cards are there repeated, for objects, and when this .relationship is represented by a steady modification in three different directions.

Having now particularly described and ascertained the nature of my said invention 5 and in what manner the same is to be performed, I declare that what I claim is 1. In a device for. ascertaining colors, a plurality of cards of celluloid, means pivotally connecting the several cards together,

10 each card having groups of openings arran ed in. rows concentric to the axes of the car and spaced in'the radial direction of the said cards, difierently colored specimens applied to the cards at the sides of said openings. v

2. In a device as claimed in claim 1, characterized by the fact that the location of the specimen of color is given by the number of the fan segment and by the location of the color specimen thereon.

In testimony whereof I have signed my name to this specification.
