METHOD OF MAKNGr EMBOSSED DESIGNS.

Application filed August 2, i928. Serial No. 296,969,

The main objects of, this inventionare to provide an improved method of producing embossed lettering or'designs; and 'to proride an improved method of applying a fusible material such as sealing wax to a'suppcrting Janel for aroducin an embossed advertisino` card or other sign which is decorative.

An illustrative' .embodiment of certain means for carrying out this improved method is shown in the accompanying drawing, wherein Figure l is a perspective of four matrix blocks supported on a base panel for receiving the fused sealing wax from an applicator.

Fig. 2 is an enlarged transverse section taken on the line 2-2 of Fig. l and showing the sealing wax after it has congealed.

Fig. 3 is an enlarged detail in perspective showing a portion of the embossed matter.

Embossed advertising display cardsand other signs have-been made commonly with sealing wax applied to a receiving sheet or card. VVaxes of different colors have been used for the letters or other designs.

Heretofore, the process of making such embossed designs has been performed entirely with `a hand operated writing instrument,

Y from which the melted wax iiowed directly onto the receiving sheet without the use of a matrix. The'instrument was used somewhat like a fountain pen. In view of the fact that it was all free hand work, the prior method was slow and expensive, required skilled oplerators and artists and no two pieces of work were identical. The prior method was, therefore, impractical for quantity production.

My improved method of producing embossed designs includes the use of a matrix adapted to be placed on the base panel for receiving the melted wax. rihe matrix is made of a material, preferably metal, to which sealing wax will not adhere and the back thereof is open and unrestricted so that thetop surface of the sealing wax is permitted to form a natural convex meniscus, which clearly distinguishes the design from one having molded characters.

When liquid comes in contact with a solid which is moistened by it, the liquid is raised upwards against the sides of the solid and its surface, instead of being horizontal, is slightly concave, forming a concave meniscus, if, on the contrary, the solid is one which is not moistened by the liquid, the liquid is depressed against the sides of the solid and assumes a convex shape, forming a convex meniscus.

` lVhen melted sealing wax comes in contact with metal and the surface of the liquid is not cc-nned by a top or cover,`it forms a natural convex meniscus.

The improved matrix may comprise a single block for each design or a plurality of separate blocks each of which contains a portion of the design as, for instance, a single letter.

ln the form shown in the drawings, a plurality of separate matrix blocks l are supported on a base 2 for receiving a fused medium, such as sealing wax from an applicator 3 or other suitable device.

The blocks l are made of metal or any other suitable material to which the fusible medium will not adhere and the base 2 may be made ofV paper, card-board, wood or other material to which wax will adhere.

The letters or other characters extend through the block, so that the back of each block is open and unrestricted. Certain let ters, such as R, require bridge portions 4. to support an intermediate part, such-as the part 5. Sufficient draft is provided in each matrix to permit the block to be readily withdrawn after the wax has set.

The applicator 3 may be of any desired construction. in the form shown, it includes a magazine 6 adapted to contain the sealing wax, which is ejected through a nozzle 7 controlled by a valve mechanism 8. An electric heater 9 is provided for heating the wax. rlhe magazine is supported on an arm 10 pivoted to a link 11, which is rotatably mounted on a standard l2, whereby the nozzle 7 may be manually shifted to any desired position over the blocks l.

In carrying out this improved method, the base 2 is placed in a horizontal position on a table or other support, on which the standard l2 is mounted. rihe matrix blocks l are then placed in the desired position on the base 2. The operator then moves the applicator nozzle over each letter and opens the valve mechanism thereby permitting the melted wax to flow through the open back of each natrix to form the letters 13.

YWhen the sealing wax comes in contact with the metal walls of the matrix, the top surface of the wax forms a natural convex meniscus 14, which gives the finished design an appearance which is exceedingly attractive. Y Aft-ei' the Wax has hardened, the nmt-i'ix blocks lare reino-ved foi' further use.

It- W'ill be understood that details o'i' the construction shown may be altered o1 omitted and steps in the method varied without de gesl with convex meniscus, and then Separat- 2. The method of making embossed designs which consists 1n providing a base to which sealing Wax -will adhere, placing upon the base a matrix having an unrestricted open lrmoleundlefned iby Walls to which said sealing Wax will notiadheie, intioducng fused seuling Wax through the back of said mat-fix,

allowing said Wax to Cool .so as to oongeal with a convex meniscus, and then separating seid matrix and hase.
