MOLDED INDICIA-BEARING PRODUCT AND METHOD OF MAKING SAME- Filedsep't. 27. 1959 2 sheets-sheet 1 Aus. 1, 1944` J. A. Gus HAL 2,3.'=.4,zs57- MOLDED INDICIA-BEARING PRODUCT AND METHOD OF MAKING-SAMEv Filed sept. 27, 1939 2 .sheets-sheet 2 Patented Aug. 1, 1944 UNITED STATES PATENT OFFICE MOLDED INDICIA-BEARING PRODUCT AND METHOD F MAKING THE SAME 12 Claims.
This invention relates to a new and novel type of molded product and to the method of making the same.
More particularly, this new and novel type of product may serve as a name plate, an indiciabearing member, a dial, or like device to which the invention may novelly lend itself.
Such devices are usually made with indicia outlines and designs formed thereon by separate .operations and protrude from or lie flush with i the front face. The essential consideration is to secure a pronounced contrast of the indicia so that it will stand out and thereby effectively attract attention. Whether in relief, flush or recessed, the indicia and design are usually differently colored with respect to the background and made by separate molding operations.
An object of the present invention is to provide devices of thisv type of essentially different construction, whereby the characters, design or indicia peculiarly stand out in very decided contrast and present an unique appearance not heretofore obtainable.
According to the teachings of this invention, the body is made of transparent material and is adapted to be molded into any desirable form, the transparent material preferably being a plastic substance and provided with recesses therein at its rear face, these recesses representing the characters, design ,or indicia to be formed. By a simple coating operation, these characters, design or indici-a are then made to assume their distinct and independent form and made to appear to exist independently of the body but embedded within, having the appearance of being molded therein separately and being of diierently colored material, the effective contrast being very pronounced. A second coating may be applied upon the rear face, or otherwise provided, in order to accentuate the contrast, this second coating serving, in effect, as a background and causing the transparent body to become somewhat light reective which tends to make these characters, indicia or design more noticeable and attractive.
Certain variations of the invention may include making the characters, indicia or design slightly transparent in character by using a paint or L coating permitting the passage of light therethrough so that these portions can be illuminated to stand out in a very novel manner against an opaque background. A very pleasing and attractive appearance can be produced through the transparent body when the'se portions are of dif- 65 Fig. 14 is a section through a mold in which ferent colors and are illuminated. Also, the background may be transparent to the extent of transmitting light therethrough and the characters or indicia may then be opaque so that further attractive combinations will be obtained that emphasize thecharacters or indicia and produce an exceptionally novel device. y
Moreover, the invention is also directed to a device of this type wherein the indicia characters or letters, and possibly other portions, are formed' by a second molding operation of diii'erently colored plastic material, and the remaining recesses are either treated in the manner above described or filled with materials producing the desired effect, in combination with the indicia, through the transparent body.
Other objects and advantages of the invention will be apparent from the following detailed description taken in connection with the acco'mpanying drawings which form a part thereof.

" The device chosen to illustrate the invention being molded in the shape of a body desirable for an article to be made may be used.
In the molding operation, recesses are formed in body I inwardly from rear face A2. The extent of these recesses, their shape and their depth depend upon the lindicia to be formed, or the design to be made, either in conjunction with the indicia or alone. The term designf as used herein, may include scroll work of different formations, or relatively iiat .-areas, of various colors to form fanciful patterns, either to be used with indicia or alone, but mainly in connection with name plates or the like.
In Fig. 1, the medallion is Vshown with indicia 3 and a design or pattern 4. Indicia 3 may be a trade name or other characters like that shown at I. As illustrated in Figs. 1 to 6, inclusive, indicia 3 and 5 are `formed by recesses 8 and 1, while design or scroll 4 is formed by recesses 4'. 'I'hese recesses may be formed in a single molding operation of body I.
The walls of recesses 6 and] are`then sprayed with a material 8 that maybe opaque and of a given color. A stencil 8 is placed'over face 2 and held in position upon mounting pins III formed upon body I, these pins being used as a means and causing unnecessary waste of material andlabor. I
It will be understood that recesses 'I may be provided with a coating of a diilerent color than the coating for the walls of recesses Ii. 'I'his may be done by employing separate stencils for the spraying operation of each set of recesses. yAfter coating 8 is thoroughly dried, a second coating face 2 and is allowed to cover the walls of recesses 4', as well as the material 8 upon the walls .of recesses 6 and 1 that have already been coated. The second coating is then allowed to dry thoroughly. The second coating thus acts as a background and may be seen through the front face I2 of body I everywhere except at those recesses 6 and 1 that we irst provided with coating 8.
To illustrate the contrast that may be effectively provided for indicia, such as 3 and 5 with respect to the design designated broadly as 4 and the background surface constituting rear face 2, coating 8 may be a brilliant red and coating II may be an aluminum paint which will provide a very desirable contrast and still reect sumcient light to cause the indicia to stand out in relief in an embedded relation in transparent body I. The reilection of light both from front I I is applied by spraying across the entire rear face I2 and the coating II upon rear face 2 tends 7g assess?- to emphasize the indicia and make it appear as i! separately formed but molded in this transparent body I. this result.
The device shown in Figs. 1A to 7, the process used to produce the indicia and ornamental'.
scroll work are particularly novel. l Spraying material I upon the walls oi recesses l .and 1 and using stencil l to protect recesses 4 and rearv materials in a simple and inexpensive manner to produce the effects desired, namely, the tor- ,mation of indicia and like characters in boldrelief within transparent body I ina way to produce the effect that such indicia and characters have been molded within by separate operations.
Hence, not only has a new product been produced but also a novel process devisedthat ef)- ilciently and economically produces this new product.
The new product is designed to make it appear' Apattern I 8 representing in general the pointer of a dial. 'I'he walls of recesses I5 are covered with a material I9' of a given color and preferably opaque or translucent. Material I9 may be sumciently transparent in regard to the passage of light that the rays of a lamp in back of body I5 may be transmitted therethrough to provide an illuminated pointer. AA coating 20, preferably opaque, may then be applied to rear face I1 and material I9 upon the Walls of recesses I6, but only upon the rear face I1, as shown in Fig. 10, if material I 9 is to permit light to be transmitted therethrough to provide an illuminated pointer I I. Likewise, a-very novel effect can be obtained if material I9 is opaque and background coating 20 isv somewhat transparent to permit light to pass therethrough. y In either case. pointer I8 will very novelly stand out and readily be seen.
A still further embodiment or extension of the invention is shown in Figs. 11 to 13, inclusive. Body 25 is likewise formed of transparent plastic material having a series of recesses 26 and 21, recesses 28 representing the characters of indicia 3 and 5, and recesses 21 representing the scroll work 4, these recesses being preferably formed in and during the molding of body 25. The article as it appearsv after the nrst molding is shown in Fig. 13. It may then be placed in die members 2l and 29 and material 3l) injected through pessages 3|, or in any suitable manner, into all recesses 26 or any number of them to form indicia I or indicia 5, or both, in a single or multiple operation whereby indicia 3 and 6 may be of material of the same or different color. That is to say, the word Motorol may be of the same or dierent color as the word Model and the number "9-69." Recesses 21 may then be coated with a material 32 of a given color that provides the proper background. In the same manner as shown in Fig. 9, material 32 may be transparent to the extent of permitting the transmission of l'hedesign4slsotendstoaddtov light therethrough while indicia material I may be opaque. Thus, the background will be illuminated and may be of a colorthat will contrast with the indicia which will emphasize the relief effect of the indicia and make the latter stand out very effectively. On the other hand, the indicia material may be transparent to theextent of permitting the passage of light whileI material I2 may be opaque. Thus, the indicia only will be illuminated and, if they are of different' colors, a
- very effective and fascinating display will be proplastic transparent material having inwardly ex- -tending lrecesses of substantial depth having side walls substantially normal to their bases and conforming in size and shape to predetermined indicia or design to be displayed through said transparent body at its front face, a material of a predetermined color and light transmitting capacity upon the walls of said recesses to distinctly characterize said indicia or design, and a second material of a predetermined color for said rear face thereafter embedded in' said structure, independently of said rear surface.
