Improvements in Tanning.
I, ERNEST GEORGE SCOTT, of 67, Lord Street, Liverpool, in the County of
Lancaster, Chemical Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the tanning of hides or skins.
At present much time is lost in tanning by reason of the difficulty of getting the
cleaning and tanning solutions into intimate contact with the hides or skins to be
tanned.
In order to facilitate this I place the hides in a suitable vessel provided with
inlet and outlet cocks and arranged in connection with suitable exhausting
apparatus. This vessel is then exhausted by means of the vacuum pump, the air
being removed not only from the vessel but also from the pores of the hides. I
then let in the solution with which the hides are to be treated and nearly fill the
vessel with it. The pores being freed from air the solution enters them readily and
so gets right into the substance of the hides causing the action to take place
quickly. After a suitable time air is admitted to the top of the vessel and the
atmospheric pressure drives the solution even more completely into the pores
of the hides or skins.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The described process for tanning hides or skins, such process consisting in
placing the hides or skins in a vessel, in exhausting the air from the vessel, in
introducing the tanning solutions into the exhausted vessel and in then re-
admitting air into the vessel, substantially as, and for the purpose, hereinbefore
described.
