BRAILLE MATRIX.
No Drawing. Original application filed December 24, 1925, Serial No. 77,616. Divided and this application filed April 15, 1926.
Our present inventionpert-ains to the process of producing a matrix and is adapted for use in duplicating Braille transcriptions and it contemplates the provision of a simple and inexpensive matrix that is so constructed that it may be produced with but a small amount of efiort and Without the employment of skilled labor. The matrix itself being readily adapted after its preparation to produce the Braille transcriptions .in any manner to which itmay adapt itself.
The subject matter of the specification and claim of this application is divisional of our parent application for process of Braille transcription filed in the United States Patent Oflice December 24, 1925 and bearing Serial Number 77,616.
The manner in which the matrix is pro duced will be fully understood from the following specification and claim.
In producing our novel matrix it is essential that an initial step, Well known in the art, be taken in orderto carry out the purpose for which the matrix is provided. This initial step consists of the preparation of Braille writing of the matter to be duplicated and is brought about by the use of a thin sharp point preferably of the construction used in the Hall Braille writer for the purpose of transcribing. We prefer that oiled Cromwell bond paper or the equivalent be used for embossing.
The Cromwell bond paper referred to may be of two forms; for instance a heavy paper or a lighter one, the heavier one of which weight of 118 pounds with a bursting strength of forty-nine points with respect to 500 sheets and of a size x 40. This paper is formed of a coniferous chemical wood fiber 65% and ground wood fiber whereas a lighter formof Cromwell bond paper 34 x having a weight of 1 08 pounds with a bursting strength of 94- points per 500 meets may beused. The fiber comtil coniferous chemical wood fiber 30% and manila and jutefiber 70%. In testing this paper the weight and strength were made under standard conditions of R. H. and degrees F. temperature.
Our novel matrix consists of one part Certus glue or its equivalent and six parts of dental plaster. These ingredients are position of this latter paper is comprised of Serial No. 102,334.
compounded by placing one part of Certus glue wit-h an equal quantity'of water in a china dish and permit same to dissolve for about five minutes. complished, six parts of dental plaster are added and in adding the dental plaster to the dissolved Certus glue we alternate with water until the mixture is of the consistency of cake icing. The embossed oiled bond paper above referred to is placed on a piece of thick carpet with the embossed side down. We then apply the mixture of Certus glue and plaster to the underside or unembossed side of the paper and particular care must be taken to fill in the dots or characters of the Braille writing by pressing the mixture with a glaziers knife. This operation must be carefully carried out in order to work the mixture into the dots until a smooth surface had been obtained and so that there will be no lumps remaining in the mixture either on the surface abutting the embossed paper or the outer surface of the mixture. simple operation will cause the embossing to be fortified against pressure. Then this has been accomplished the mixture is allowed to dry for approximately twenty-four hours and when well dried we apply a heavy coat of shellac to the unembossed side of the mixture. This coat of shellac is permitted to dry to. the point where it is not sticky and then a thin light coat of shellac is applied on the embossed side of the plate. This produces our completed matrix which is ready forany form ofduplicating to which it is applicable. Certus glue, we have found gives'the best results and is purchases able on the market, especially in foreign countries and is known as Colle Certus or- Certus glue and because of the factthat it has the strength, consistency and clean cleavage not to be found in other glues, it
It will be distinctly understood that the ingredients entering into the make up are readily and inexpensively obtainable and that it requires no exceptional skill to produce our novel matrix.
Having described our invention, What We When this has been 210- This etuim and desire to secure by Letters Patent; is:--
A Braille matrix for embossing paper, comprising an embossed sheet 01 oiled bond paper provided on its rear face with a layer of glue and dental plaster filling the embossings to thereby reinforce them and a coating; of shellac covering and protecting the (EXPOSOtl Face 01': the reinforcing layer.
In testimony whereof We have hereunto setour hands.
