Description

UNITED STATES PATENT OFFICE.
JAMES H. CRAIG, OF INDIANAPOLIS, INDIANA.
, IMPROVEMENT IN COMPOUNDS FOR GLUE.
Specification forming part, of Letters Patent No. 177,474, dated May 16, 187 6; application filed March 7, 1876.
To all whom it may concern:
Be it known that I, JAMES H. CRAIG, of Indianapolis, inthe county of Marion and State of Indiana, have invented certain new and useful Improvements in Glue; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it.
My invention relates to an improvement in glue; and consists in the ingredients compoundedin the proportion and in the manner substantially as hereinafter set forth and claimed. V
To prepare the said glue I take three pounds of common glue, and add to it two ouncesof dry weather. The carbolic acid serves to prevent decomposition. The English precipitated chalk serves to neutralize the effect of'any acid that might arise by partial fermentation or otherwise, and, with the white lead, gives body to the glue. The compound is one also that will readily set, and is applicable for all purposes for which glue is ordinarily applicable, and, in addition thereto, forms a strong cement for broken earthenware, plate-glass, 8220., without being objectionable, as ordinary glue is, on account of its ofi'ensive odor. I
find, moreover, that any glues known to the trade are very materially improved by the addition to them of the three last-named ingredients, and I do not, therefore, limit myself to the mixture of the three ingredients hereinbefore described. For, instead of employing common glue, I may employ any other ordinary glue, oranyother glue known to the trade,
the essential feature of my invention being a glue which possesses the three ingredients, dry white lead, English precipitated chalk, and carbolic acid; and these may be compounded with ordinary glue alone, as hereinbetore described, or other ingredients may be employed With them.
These proportions of white lead, English precipitated chalk, and carbolic acid may be varied somewhat to suit different glues, and for use for different purposes; but I have found that the proportions herein described form a very valuable and satisfactory compound with ordinary common glues.
What I claim is- 1. The glue herein described, consisting of common glue, dry white lead, English precipitated chalk, and carbolic acid, in the pro: portions substantially as herein described.
2. The process of improving glues, consisting of mixing with the. said glues dry white lead, English precipitated chalk, and carbolic acid, in the proportions substantially as herein described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
. JAMES H. CRAIG.
