Description
lowing is a specification ann fi AT P TENT OF GE:
EMIL' FYI. nrnrnnrcfis, OF PHILADELPHIA, PENESYLYANIA,
'- iMPReVEMENr m WATER-REPELLENT 'DUBBlNjGl-OR ma.
Specification forming part of Letters Patent N0. 150,363, dated April 2 8, 1874: application filed April 15, 1824. Y Y H Be it known that I, EMU; F. DrETERIcHs, of
Philadelphia, Pennsylvania, have invented a Water-Repellent Dubbing, of which the fol- Leather, after being tanned and dried and not otherwise finished, retains a rigidity which increases with time, and to counteract which ,it is necessary to grease or dub. the leather.
The dubbings commonly employed for this purpose consist of .oils more or less mixed with tallow', or sometimes with tallow and rosin, and often with tallow, wax, rosin, and other ingredients,fthe whole suspended in some dry-r Even the well-known. French degrasi is seldom usedwithout a large admixture of tallo'w.
ing or yolatile oil.
The benefits of such dubbings last onlyuntil the decomposition of their component parts has taken place. vThis decomposition rapidly results from the changes from moisture to dryness, or vice versa, undergone by the leather.
'- In the case of boots and shoes it is occasioned by the perspiration of thefetmr in'case ofharness by perspiration from the body of the animal, or iii-either case it results from. the
ammonia in rain and snow water,".and i'n cases fromniany other influences, not ofnly f during use, but also during storage. their the dubbing has become thus decomposed the leather hardens and rots.
The composition which I prepare for dubbing and stuffing leather differs from those ,above mentioned by being entirely free from rosin, wax, fallow, and any of the drying or volatile oils. It is composed of insoluble wa ter-repellent and pliant in gredi en'ts only, which settle around the fibers, protect them and render the leather water-repellent and permanently soft and pliable.
This water-repellent dubbing-I prepare by heating neats-foot oil, or other fatty matter of similar nature, until all moisture is expelled from it and its gluten has been destroyed, and
I then' dissolve in it caoutchouc in, a divided lon of fatty matter,
When it; i d ir d to accelerate the-process of mixingthe caoutc'houc with the fatty matter, and also to preserve the light color of the mixture, I use caoutchouc which has been pre- 'Viously softened byvolatile hydrocarbon, and after mixing this thoroughly with the heated fatty matter, I continue applyingheat by means of a water-bath, until all the hydrocarbon is evaporated and a' uniform mixture of the caOutchouc and fatty matter obtained.
For denser compounds, such as are required when the dubbing is intended for stufiing process-employed in finishing leather, I add to the mixture obtained by either of the above-- described processes parafline or crude stearine (such as is pressed from crude lard',) or a mixture of both, as-much as twenty per cent-.-
In this case'the caoutchouc may-be dissolved in the parafline or stearine by the aid of heat,
and then mixed with the heated fatty matter.
To the oily compound thus formed 1. now-add a portion of the oleate, stearate, m-argarate,
or palmetate of alumina, (wluchare compounds insoluble in water,) in the proportion of from ltwo to-ei-ght ounces of any of the alumina compoundsto sixteen ounces of the oily c0m-' pound, and maintain heat until all moisture is .expelled and a uniform combination obtained.
Instead of thefatty acids last mentioned; any other fatty acid may be substituted.
I claim'" As a new manufacture, water-repellentdubbing', composed of.fatty matter, caoutchou'e,
and a compound ofalumina insoluble-in water, with or without "parafii'ne oiY-s'tearinjefall. in the proportions mentioned, substantially as set forth. s F. vnr'nrmucus.' Witnesses: 1
