ALBERT FREEDMAN'. OF BROOKLYN, NEW YORK;

MANUFACTURE (IF IBICOLORED SPECTACLES.

Application filed July 2,\ 1924. Serial No. 723,665.

lenses of transparent or translucent 11121- terial, but of different colors or tints, as for instance one of blue or green and one of red or orange color,these spectacles, so called, while of utility mainly in viewing pictures whereby certain novel effects are attained, being designed for use primarily suitable fibrous 7 material, having imposed I bellishments' fora pl as mediums for advertising, and being gratuitously distributed, so that cost of production is an important consideration as well as simplicity and perfection of form and structure.

To this end the invention consists essentially in the process of manufacture herein set forth, and described and claimed specifically, a distinctive feature being the method of plural production in series, whereby the time, labor and cost involved are reduced to a minimum degree while the resultant product is of uniform character and efficiency.

In the accompanying drawings I illustrate a practical. embodiment of the essential features of my invention by views showing the successive steps in my process of the manufacture, simultaneously, of any plural number of eye-glasses of the character designated, although I do not wish to limit myself to the identical configuration and structure of parts and appurtenances therein shown by way of :exemplification, since changes may be made in minor details, and mechanical expedients resorted to, with like results, and without departing from the spirit and intent of my invention in this respect.

With this understanding a Fig. 1, represents a face view of a portion of a sheet of paper, cardboard, or other thereon, as the first step in the process of manufacture, the reading matter and ema 'ty of. spectacles,

the medial portion on either side of the prescribed line of fold being shown, and both ends of the sheet being broken away, the sheet being otherwise full size;

Fig. 2, is a View like unto Fig. 1, showing the sheet perforated with the lens openings.

which are coincidental when the sheetis folded;

Fig. 3, is a view of the reverse or inner side of the full sheet, reduced to approximately one half size, of the sheet prepared.

as in Fig. 2, and showing the strips of trans parent'colored lens media positioned overthe lens openings on one half of the sheet preparatory to the'folding over thereon of the other half of the sheet;.

Fig. 4, is a front view of a folded sheet Fig. 5, is a rear view of the portion. of. completed sheet shown in Fig. 4;

Fig. 6, is a view of one side of the completed roduct; and

Fig. a transverse section thereof taken upon plane of line 7-7, Fig. 6.

The superimposable basic mount sheets or portion of the layers S, S are composed ofv anysuitable material adapted to the purpose, such as paper of suitable thickness, cardboard, or in fact any fibrous oreven. textile material of requisite consistency and pliability. These V superimposable mount sheets S, S are preferably although'not necessarily formed of one piece of material, as illustrated in Figs. 1, 2 and 3, of the drawings, with a scored or otherwise prescribed line of fold' 5 s, between them, the sheet or section S, be- I, ing what may be designated as the front layer of the two ply unitary mount sheet resultant from the permanent imposition of the two figures S, S, one upon the other,

back to back, as hereinafter set forth In \i other words, while there are certain advan tages in including and forming both sections S, S of the basic mount in a single preliminary sheet, such, for instance, as expeditious printing and manipulation, this method is not indispensable, since the sections or plies S, S, may consistof separate-o 1y printed and prepared sheets for superimposition to form the bas1c support, between them, for the lens material L, L I

With this explanation, and following the specific method of manufacture illustrated 1'1 sheet or section S, S are printed or otherw1se inthe drawings, the outersurfaces of each m q l -the h d re Wi s matter, advertising, or embellishments, as

indicatectin Fig. 1, of the drawings.

The basic sections S, S then are diestamped to form the sights or lens openings 8, s, illustrated in Fig. 2, of the drawings, after which the colored lens strips L, L are positioned (as indicated in Fig. 3, of the drawings) on the inner or back side of one or the other of the basic sections S, S and the latter are then superimposed, back to back, one upon the other, and united integrally with the said colored lens strips L, L between them. This permanent joining of the basic sections S, S back to back, with the transparent color strips L, L interposed between them, may be effected by any suitable means, and I do not limit myself in this respect, as any adhesive or equivalent unitary incorporative expedient may be resorted to, as may be found most suitable in practice, in accordance with the nature and object of the finished product desired.

The transparent mediums L, L are illustrated symbolically in the drawings respectively as of contrasting colors, blue and red, although other analogous colors may be used. These colored transparent lens mediums may consist of strips of gelatine or any equivalent thereof; and may be of other appropriate contrasted colors than those indicated herein.

The use of strips L, L, of colored transparent medium covering a plurality of sight or lens holes 8, s, as indicated in Fig. 3, of the drawings is obviously an advantage in 1 the process of manufacture, insuring uniformity and perfection of alignment, and reducing labor and manipulatlon to a IIllI1l mum degree in this respect.

In fact it will readily be seen that by my process of manufacture an effective, stand- 7 ardized production may be attained with a minimum expenditure of time, labor and cost, it being understood that the individual 3 spectacles or eyeglasses are die-stamped from the prepared superposed and integrally united basic sheets S, S portions of which are shown in Figs. 4 and 5, resultp ing in a plurality of specific products such 5 as shown in Figs. 6 and 7, of the drawings,

in whichs, represents the nose bridge, and

8 an extension to serve as a convenient finger hold to facilitate the use of the lenses L, Li the term lenses being used herein in a figurative sense as designating the colored eye screens or shades, the provision and use of which is the ultimate object of my invention.

It is to be understood in this connection that the configuration of the completed product shown by way of exemplification in Fig. 6, of the drawings, may be varied without deviating from the spirit and intent of my invention in this respect; and that lettering, etc. shown as imposed thereon is simply indicative of the utility of the product as an advertising medium for gratuitous distribution.

Obviously the details and steps of manufacture may be varied more or less within the scope of my invention, which consists essentially, first in preparing the outer surfaces of the basic sheets S, S byimposing thereon the reading matter or embellish ments to be shown on the corresponding outer surfaces of the completed product; then die- .j

stamping the said basic sheets to form the"? lens openings 8, s; then un1t1ng said sheets integrally, with the transparent colored mediums between them, and finally diestam we ing out the individual spectacles or glasses rom the basic structure thus attained.

It is to be understood that by the terms v feye-glasses or spectacles as herein used. I mean to imply substitutes for theopticalappliances thus ordinarily designated.

It is to be understood that my basic sheets I may be made from continuous webs: of material fed from rolls.

What I claim as my invention and desire: in

to secure by Letters Patent, is:-

1. The method of manufacturing bi-col-g ored spectacles consisting in imposing reading matter on the exterior surfaces of basic mount sections stamping out sight openings in the said basic sections, applying a trans' transparent media between said sections and folding the said sections one upon each other and enclosing the said media.
