PROCESS OF- TREA TING LEATHER.
SPECIFICATION forming part of Letters Patent No. 645,056, dated March 13, 1900. Application filed August 30, 1899. Serial No. 728,990, (No specimens.)
To all whom it may concern.-
Be it known that I, RICHARD BUCK ARTHUR, shopman, a subject of the Queen of Great Britain and Ireland, residing at 4:5 Nicholson street, Ballarat, in the county of Grenville, Colony of Victoria, have invented a certain new and useful Process for Treating Leather and Similar Substances, of which the following is a specification.
The object of my invention is to render leather and similar substances unimpaired by contact with or immersion in water which is affected by minerals. In the past leather and like substances have suffered serious injury under such circumstances; but with my process such materials, whether used for boots, shoes, harness, pumps, or any otherpurposes, are after treatment unaffected by the presence of water impregnated as above described. -My invention consists in first tanning the hide or skin or other substance in any ordinary way by-chrome or bark or other tanning agencies and then suspending it in order that it maylose some of its moisture, after which, if necessary, a split or shaving is removed, allowed to almost dry out. It in a rotating chamber or drum of any desired shape to absorb the first solution, which is composed as follows: Make a mixture of five (5) pounds of alum, five (5) pounds of chalk, three (3) pounds of best glue, and about ten (10) gallons of water. The cham her is then set in motion and rotated for about four (4) hours or untilthe solution has thoroughly penetrated the substance, which is then removed and allowed to drain. After draining it is hung up to almost dry out, when it is ready to receive the second solution, composed as follows: Dissolve ten (10) pounds of pure asphaltum. and one (1) pound of indiarubber in about three (3) gallons of turpenor other solvent. Then add twelve (12) pounds of paraflin-wax and twelve (12) pounds of beeswax and four (4) pounds of sugar of lead dissolved in oil. Reduce to the consistency required with boiled linseed-oil, paraffin-oil, or other oil. Have the whole thoroughly commingled by heating and agitation.
Previous to receiving the second solution is then placed the chamber by steam, hot air, or other means is heated to a temperature of about one h.un-'
dred and thirty (130) degrees Fahrenheit,-
provision being made, if steam is used,-to drain out the accumulated water. After this the solution, which must also be heated to about the same temperature, is placed with the leather or other substance in the chamber, which is then set in motion and run for about four (4) hours or for such shorter or longer period as will enable the'solution to thoroughly permeate the leather. This is easily determined by the practical tanner handling the leather. It is then removed from the chamber and, being set out iwthe usual way,- is hung up to dry, after which it is finished by the usual trade methods employed in fin ishing ordinary leather.
The quantities and times given above are approximate, since diiferent descriptions of material require diiferent proportions of the above ingredients, which vary with the class of the leather and the purposes for which it is intended.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is'
An improved process for treating leather and similar substances consisting of tanning the leather in the ordinary way and then placing it in a rotating chamber containing a solution of alum, chalk, glue, and water in the approximate proportions specified ,then draining and almost drying out, then placing it in a rotating chamber heated to a suitable temperature withasolution also heated as before described consisting of asphaltum, india-rubber dissolved in turpentine or other solvent to which is added paraffin-wax, beeswax and sugar of lead dissolved in oil and of the approximate proportions specified, then finishin g in the ordinary way all as and for the purposes hereinbefore specified.
In witness whereof I have hereunto set my hand in presence of two witnesses.
RICHARD BUCK ARTHUR. Witnesses:
WALTER J OSEPH NANSGAWEN, THOMAS HENRY JOHNSON.
