BMPROVEMENT IN COMPOSITIONS FOR INK ROLLERS OR PADS.
Specification forming part of Letters Patent No. 148,003, dated February 24, 1874; application filed July 26,1873.
To all whom it may concern:
Be it known that we, ALBERT S. TAFI and GILBERT T. TAFT, of Auburn, in the county of Cayuga and 'State of New York, have invented an Improved Composition for Ink Bollers or Pads and we do hereby declare that the following is a full, clear, and exact description thereof.
This invention relates to that class of compounds used by printers in printing; and consists in a composition formed by mixing tallow, lard or lard-oil, or other fatty substances, Barbadoes tar, balsam of fir, or any other balsams, gums, glycerines, lime, or honey, with glue.
We first prepare a solution of lime by percolating distilled water through fifty pounds of well-burnt lime until the percolate shall measure ten gallons. Soak onehundred pounds of glue in this solution. When properly softened, transfer the glue to a water-bath, and, when dissolved, add from three to five pounds of tallow, and from fifty to one hundred pounds of glycerine. The amount of tallow and glycerine necessary to be used depends upon the strength of the lime-water, and can only be determined by experience and testing it from time to time during the process of manufac- I Vhen these last articles have become well incorporated with the glue, add from two to three pounds of balsam of fir, or its equivalen t, one pound of Barbadoes tar, or its equivalent, and from six to twenty-five pounds of honey. The necessary amount of honey depends upon its age; if old and fermented it will require more. Melt all together, and continue the heating until all the water has evaporated.
o are aware of the composition of the several compounds in the market; but in several instances, which we will point out, they differ materially from ours. Ours is the only composition in the market that can be used in damp, warm weather. It is the universal complaint among printers that during such warm, damp weather they must either suspend printing or fall back on the old glue-and-molasses composition. Therefore they are, withbined.
out an exception, deficient in suction. Ours retains that suction perfectly during all kinds of weather, hot or cold, wet or drya consideration which, a great many printers inform us, is of more value to them than all else com- Ours is perfectly neutral in that respect.
YVe claim, also, that our composition can be remelted a great number of times without imthe glue soak in this percolate from fifteen to thirty minutes, according to the thickness of the glue-the thin glue fifteen minutes, and
the thick thirty minutes. Then pour off the percolate, and cover up the vessel containing the glue and allow it to stand twelve (12) hours, or until the glue is perfectly saturated with the percolate.
The action of the lime, in combination with the other ingredients, enables the composition to retain its powers of suction through damp, warm weather, as well as in cold weather, which is the great desideratum in roller composition.
What we claim as new, and desire to secure by Letters Patent, is-- A compound for inking type, consisting of one hundred pounds of glue, the same having been treated with lime and water, as described, twenty pounds of strained honey,
three pounds of Barbadoes tar, six pounds of balsam of fir, and fifty pounds of glycerine.
