mrnrion MOTHEROF-PEARL AND rnocnss on MAKING THE SAME,

No Drawing.

This invention relates to imitation motherof-pearl and the process of making the same. The object of the invention is to provide a plastic composition in imitation of motherf of-pearl and having therein. the peculiar Wavy sheen or lustre-effects which is characteristic of the genuine mother-of-pearl, the Wavy sheen or lustre effects being indiscriminately interspersed throughout the compo- 1 sition. J

In my pending application Serial- No. 672,470, filed -.November 3, 1923, I have shown, described and claimed an apparatus for and process of manufacturing, imitation l mother-of-pearl, wherein apigmeht is in :corporated in and uniformly distributed 'tliro'ughouta, massof plastic material,- and this mass :is then so manipulated as to cause the incorporated and distributed particles to become laid or disposed in a w particular manner to give a substantially uniform directional trend thereto. The mass so treated, in the form of .thin sheets, is stacked into a pile and the pile compressed 'under heat and pressure into a homogeneous mass, and is ready for the market, or it may besheeted into th fployed in the fab inerc-i'al articles. According to th rication ofvarious come mode of procedure set 1" forth and claimed in my application above identified, after the desired pigment is g thorou hly incorporated in and distributed "throng out the plastic massythe mass is so as manipulated as today or dispose the part'if-l-jlt'icles of pigment in a substantially uniform directional-trend. One way of accomplish- ;in'gfthat result is. disclosed in said applica- --;.t'ion,= ,whereby the mass containing the in eoilrolr-porated and distributed pigment particle's, for example, fish, scale pigment, is

' heated or cooked to duced to a state of more or less fluidity or flowing plasticity. While in this state the fluid mass is forced by means of a piston plunger operatingiin' a chamber containing the said mass, and, Whil'e'still maintained underheat; through a diehaving a slit oi -.o pening*io t"fixed restricted area.

in sheets which are em the ezgtent of being're- 1924. Serial mi. 697,714.

The sheets thus produced. are then piled into a stack which is subjected wheat and pressure to form the same into a solid homogeneous block or cake. This block or cake is then sheeted into thin sheetswhich when sufficiently dried are ready for the market or for use in making various commercial articlesa I have discovered that a superior and more beautiful and delicate product is attained, and one which more closely resembles the genuine "mother-of-pearl, by producing at indiscriminately 'inters ersed points or locations in the roduct, t e Wavy lines of lustre or sheen e ects which are characteris 'tic of the genuine mother-of-pearl, and 1- 'have. discovered that this characteristic wavy lines of sheen or lustreeffect can be produced by relatively varyingthe character in some one or more respects of the thin sheets which are stacked or .piled for compression into the homogeneous cake or block, preparatory to sheeting into the thin sheets for fabrieating into commercial articles, and then interspersing such relatively diifering sheets indiscriminately in said stack or. pile.

.According' to my present invention, I propose 'tofintroduce at some point in the operation above described a more or less temporary variation in. the procedure, and to distribute at various points in the, stack orpile the thin sheets produced by the temporary variations, so that'when the stack or pile" is pressed into 'a homogeneous block or cake and then sheetedinto thin sheets, 90 suchsheets will reveal a wavy sheen or lustre eife'ct at indiscriminately positioned location's therein which imparts a highly pleasing and beautiful appearance more nearly approaching the characteristic sheen and lustre of the enuine mother-of-pearl.

I have found that this Wavy efiect may be secured in yarious ways. According" to one method, the stack or pile of thin sheets to be formed under heat and pressure is built 100' up with som thin sheets produced at one f the fluid mass through other thin sheets indisinterspersed in the stack or pile,

d at a di-fierent rate "of speed of 106 the die is increased so as to effect the extrusion at a-rate such that there is failure to thoroughly or uniformly iron the surface while others of the sheets in the pile are more thoroughly ironed or calendered.

The same result may be obtained by maintaining a constant pressure and speed of extrusion but varying the temperature ofvthe die to impart the relatively different char-' acteristics to the sheets to be stacked up in the pile.

Still another way 0f accomplishing the re-.

sult consists in employlng extruded sheets of relatively different thicknesses in building upthe stack or pile.

According to another method, the stack or pile is built up of indiscriminatel positioned sheets which are extruded tli truding pressure and temperature remaining the same.

, Another methodconsists in relatively varyin the plasticity of the compositions from which .the thin sheets are produced, as, for example, by varying the amount of solvent ermitted to remain in the inass by subjecting the same to a longer or shorter period of rollin operation.

In or er to secure the variegated effects referred to, I may also employ for indiscriminately located layers in the stack or pile, small piecesfor sections of one or another of the relatively varying sheets pro-- duced by any of the methods referred to.

The resulting product in the form of a thin sheet into which the homogeneously pressed stack or pile is cut or slit, possesses the beautiful, delicate, irregularly dispersed wavy sheen or lustre eifects which very close- I claim as new and useful, and of my own invention, and desire to secure by Letters Patent, is:-{ Y
