TOILET-ARTICLE FILLING COMPOSITION.

No Drawing.

To all whom it may concern Be it known that I, I-IUoo SCHNEIDER, a citizen of the United States, and resident of Hastings, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Toilet- Article Filling Composition, of which the following is a specification.

My invention relates to the manufacture of filled toilet articles, and is especially directed to an improvement in the compositionemployed as afiller therefor.

A large variety of toilet articles, such as hand mirrors, brushes, combs, manicure implements, various types of containers, and the like, are manufactured wholly or in part from celluloid, pyroxilin compounds, or similar substances. In order to avoid the ex pense of manufacturing such articles from solid stock, they have heretofore been con structed from a hollow shell of suitable ma terial filled with a composition providing proper strength and solidity. 7

However, the fillers heretofore employed have each been open to one or more serious objections which rendered them relatively undesirable. One source of trouble with such fillers has been the tendency to shrink after being positioned in the shell, producing weakened spots in which the shell is unsupported, and also developing a tendency to rattle.

Another defect has been the relative brittleness of the filler, causing it to crack and rattle, which not only weakens the structure of the article, but also produces an article which is unpleasant to use, reducing the saleability thereof. Other fillers have not been of proper weight, and toilet articles of the nature indicated which either too heavy or too light are inconvenient to use and much less desirable.

While filled toilet articles may be 1nanu-' Application filed May 10, 192-0. Serial No. 380,409.

ing brittle, or losing its substantially homogeneous consistency.

It furthermore must be of such a nature as to have no harmful effects upon the material of which the shell is composed.

The composition which I have invented is suitable for use with mirrors or other toilet articles of the type shown in my copending application No. 299,299, and is located therein in the same way.

I have also found that a suitable filler of this nature should remain substantially firm at temperatures above the ordinary, such as those encountered in hot climates, as well as those produced in the course of manufacture, as by buliing, grinding or otherwise operating on the shell in finishing the article.

I have found that the characteristics above outlined are possessed by a composition including a suitable intermixture of wax and a resinous or gummy substance, preferably combined with an inert filler or weighting material, such as finely powdered mineral matter. Any of the many forms of wax are suitable for my purpose, including both those of animal origin, such as stearine, tallow, beeswax, and the like, and those of mineral origin, such as commercial paraffin. I likewise may employ any of the various substances of a gummy, resinous or rosinlike nature, a great variety of which is well known to those skilled in the art. Examples of such substances are rosin, resin and gum tragacanth.

By combining the wax and gummy material in suitable proportions, I provide a substance which may be melted at a con venient temperature for pouring into a hollow toilet article, and which hardens without shrinking or becoming brittle. Furthermore, such mixture while solid may be of such a consistency that if desired it may be cut into suitable filling shapes and the shells placed thereon, this method. also being employed for the manufacture of articles of the type described. Such a filler possesses suflicient hardness to support a relatively thin shell at all points, but retains a certain slight resiliency which pre vents cracking when the article is dropped or subjected to blows,

I have also found it desirable to include with the wax and the gummy substance a suitable proportion of the weighting substance; or filler, Whose. function is primarily forming to give proper body or weight to the composition, although it also contributes a certain amount of strength thereto. For this purpose, I may employ a variety of materials, preferably in finely powdered form, and including the various mineral or rocksubstances. Examples of materials which I have found suitable for this purpose are marble dust and terra alba, the primary characteristics required being the ability to mix readily with the other 1ngredients to form a homogeneous mass which will not settle out into its component parts before it has a chance to harden and-after insertion in the filled article.

The proportions employed vary somewhat, depending upon the exact substances used. Through experiment, I have found that the best results are obtained by employing a mixture of paraflin with rosin, using either marble dust or terra 'alba as the filler. With a composition of this type, the employment of too much wax will result in a soft product which will not offer the proper support to the shell, and which will be effected by the heat of torrid climates as well as by heat generated in finishing the article. F urthermore, such an excess in wax will tend to cause such wax to gather at the surface of the composition immediately under the articleshell during filling,-causing soft spots not only readily affected by heat, but directly liable to deformation by pressure. On the other hand, an excess of rosin will produce a brittle filler which is readily cracked 'by blows and therefore undesirable from a commercial standpoint.

I have ascertained that a composition, having the desired characteristics canbe produced by mixing thoroughly the parafiin and rosin in the proportion of twenty pounds of wax to fifteen pounds of rosin. However, it will be apparent that these proportions will vary somewhat depending upon the type of wax and of gum employed. A smaller proportion of the harder gums will produce a composition ofequal hardness to that described, and a small proportion of softer waxes will likewise producethe same effect, the characteristics of'the various gums and waxes being well known to those skilled in the art, and the relative proportions employed being determined primarily by the relative hardness and melting point of theingradients. The amount of weighting material or filler, such as marble dust or terra :ilba, is determined solely 'by the weight of the article which is desired, and is therefore largely a matter of taste and thespecific toilet article in which the filler'is used. I have found that when twenty pounds of wax and fifteen pounds of rosin are used, twenty poundsof marble dust-produces a composition having the proper weight "for mirror baoksbf the type described in-"my said 00- nasenoe pending application, but such proportion of marble dust is illustrative only.

The various ingredients may be compounded in any desired way, preferably by melting the wax and gummy substance and mixing them together with the powdered weighting material. The mixture may then be poured into a suitable hollow shell and allowed to harden therein, or it may be molded or rolled while soft and plastic into suitable form, such as flat sheets, from which filler sections of suitable contour may be out. Likewise, the halves of a hollow shell may be pressed into opposite sides of a sheet of suitable thickness to produce the filled article, preferably while the sheet is sufficiently warm to be plastic. I

While I have referred to one of my ingred-ients as a gummy substance or gum, it is to be understood that this expression is not confined purely to the resinousclass of gums, but includes rosin andother substances having the physical characteristics generally and popularly included within the term gum. Furthermore, I have not used the term wax in a strictly chemical sense, but intend it to include the various substances, both of mineral and of animal or plant origin,having thephysical characteristics ordi-' narily and popularly indicated by the term wax.

Likewise, I do not intend to limit myself to a specific powdered weighting material or filler, as such substance has a Very slight effeet on the-composition, and a very wide variety of substances suitable for the purpose are well known to those skilled in the art, and may be interchangeably used, the only requisite being the capacity to form a homogeneous mixture and relative inertness toward the other components.
