UNITED STATES PATENT OFFI E.
FRIEDRICH SOHREINER AND ARNOLD SOHOTT, OF PHILADELPHIA,
PENNSYLVANIA.
MATRIX FOR STEREOTYPI NG.
SPECIFICATION forming part of Letters Patent N 0. 404,564, dated. June 4, 1889.
Application filed May 9, 1888. Serial No. 273,274. (No model.)
To all whom it may concern:
Be it known that we, FRIEDRICH SCHREINER and ARNOLD SCHOTT, of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Matrices for Stereotyping, of which the following is a specification.
This invent-ion relates to certain new and useful improvements in the matrix for stereotyping for which Letters Patent N 0. 376,348 were issued to us on the 10th day of January, 1888; and the object of our invention is to provide a stereotyping-matrix which is strong and durable and can resist the pressure of the quantity of metal on the blank spaces.
The invention consists in a matrix composed of a sheet of fabric coated and partly impregnated with a semi-dry plastic mass and provided with a backing of pulp.
In the accompanying drawing a. transverse sectional view of our improved matrix for stereotyping is shown.
We use the improved matrix described in our patent, 'No. 376,348, of January 10, 1888, and composed of a sheet of fabric one face of which is coated with a semi-dry plastic mass of glue, sirup, glycerine, and a powder, which semi-dry plastic mass also impregnates part of the thickness of the fabric. Upon said plastic face we place a sheet of thin very fibrous paper Dfor example, Japanese vegetable-fiber paper and then the matrix is pressed upon the matter to be stereotyped by means of suitable presses. \Ve thus produce a sharp and clear impression-of the type in the fiber paper and plastic mass.
The matrix remains on the type and a sheet 0 of wood pulp or any other pulp is placed upon the matrix, which sheet has been impregnated or saturated before being applied with a mixture of two parts of powdered dextrine, one part of starch, and one part of asbestus powder mixed with cold water and boiled and stirred until it has the consistency of cream. By reapplying the pressure the pulp is caused to adhere firmly to the matrix and to stiffen the same, so that when the hot stereotyping metal is applied it does not press down the matrix at the blank spaces B of the matrix A. The matrix is removed and subjected for a few moments to a current of hot air for the purpose of hardening it. The improved matrix does not warp or shrink, and the impressions are not injured or marred by hardening the matrix.
By means of our improved matrix stereotypes canbe made very rapidly, as the matrix need not to be dried on the type and the type and matrix need not to be heated'fas has been necessary heretofore, while using composition or wet paper for stereotyping. There is no need of separately backing the spaces with plaster-of-paris or compositions or cutting them out, as has been necessary heretofore.
By using our improved matrix the type is not injured by heat as it is by the old method of stereotyping. As we do not heat the type no time is lost by waiting for the cooling of the type in order to procure a second or more moldings.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A matrix for stereotyping, composed of a sheet of fabric coated and partly impregnated with a semi-dry plastic mass and having a backing of pulp firmly connected with the back, substantially as herein shown and described.
2. A matrix for stereotyping, composed of a sheet of fabric coated and partlyimpregnated with a semi-dry plastic mass, a sheet of fiber paper on the plastic mass, and a backing of pulp firmly connected with the back of the sheet of fabric, substantially as herein shown and described.
In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
FRIEDRICH SCHREINER. I
ARNOLD SCHOTT. Witnesses:
ALEX. REINSTINE, FREDRIOK FINGER.
