roxyline and the Manufacture fully hereinafter have a base of some other material,
UNITED v SAMUEL J. HOGGSON AND GEORGE (E. PETTIS,
STATES PATENT OFFICE,
OF NEW HAVEN, CONN.
SPECIFICATION formingpart of Letters Patent No. 237,279, dated February 1, 1881.
' Application filed December 31, 1880. (No specimens.)
To all whom it may concern.-
Be it known that We, SAMUEL J. HOGGSON and GEORGE O. PETTIs, of New Haven, in thecounty of N w Haven and State therefrom and we do hereby declare the following to be a full, clear, and exact description of the same.
This invention surface of which it is desired to coat treated pyroxyline, such as book-covers, printers stereotype, and other articles which have a backing or foundation. I
In the usual method of treating pyroxyline for these purposes it is prepared in a mass and rolled into sheets or pressed into molds to form the covering or veneer.
Our improved process consists in treating the pyroxyline in sheets from the fiber and applied toa foundation or backing, as more described.
We first prepare a backing or foundation from any suitable material. The surface to be coated is prepared by embossing thereon the requisite shape or ornamentation, or it may be left plain; or upon the surface to be may be laid on in colwith the size, according to the foundation or backing upon which it is to be placed. This sheet of fiber We suspend in a suitable vessel containing nitric acid, or a mixture of nitric and sulphuric acid, or of nitrate of potassium or soda with the above acids. This sheet may be placed directly in the acid or suspended over it until it attains the pyroxyline condition. It is then transferred from the acid-bath directly to a clear Then it is taken from the Waterpressed, by rolling or otherwise, to remove the water. It is then placed onto the of Articles backing or foundation and secured by any suitable adhesive material. Then the backing, With the sheet of pyroxyline upon it, is placed in a bath of acetic ether, alcohol, Wood-naphtha, or any of theknown pyroxyline solvents, until the sheet is converted into a gelatinous condition, but still retaining its shape. then removed from the bath, and if the backing is embossed for ornamentation it is then placed in the same dies and re-pressed, which brings out the embossed ornamentation on the surface of the sheet or veneering. If it be fiat, with colored ornamentation on the foundation, then it is simply rolled to finish the surface, the covering or veneering being transparent.
If the transparency of the veneering is not requiredthat is, if it is desirable to produce a colored or opaque covering for the backing-the requisite coloring-pigments are insheet may be treated separately and laid over the backing and pressed or rolled thereon but the best results are obtained by applying the sheet to thebackin g before the converting process is performed.
We claim- 1. The method of treating pyroxyline consisting, first, in preparing the fiber in a sheet form and subjecting it, while in such sheet acid-bath to form the pyroxyline sheet, then subjecting the pyroxyline sheet to a solvent, substantially as described.
ANUFACTURE 0F ARTICLES THERE- 2. The method herein described for surfacing articles with a veneering made from pyroxyline, consisting in first preparing the pyroxyline in sheets, then applying it to the surface of the article to be covered, then subjecting the coating thus applied to a solvent, substantially as described.
