Process for Treating and Preparing Raw Hides for Travelling Trunks,
Bags, and the like.

I, EDWARD SAMUEL COOK, of 274, South Lambeth Road, County of London,
do hereby declare the nature of this invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the follow-
ing statement:-
This invention has for object, preparing raw hides by a certain treatment or
process to render them waterproof and of a shape by moulding to be made up,
such as thread stitching, rivetting, or we sewing into travelling trunks, bags,
and the like.
For the purpose of this invention, I take raw hides with or without the hair
on them and cut them into an approximate shape for the part of the travelling
trunk or bag they are intended to occupy. These I clean of superfluous scale
or what may be termed refuse and cut them up to various shapes, such as for
bottoms, tops, sides, or ends of the trunk or bag to be made. I then place them
in a revolvable dium containing water or through which by hollow trunnions a
slow stream of water can be passed for soaking and further cleansing the pieces
so inserted and treated When the escaping water runs fairly clear and the
pieces have been sufficiently long for thorough saturation and softening I
remove them and strain them on moulds of the required shape the several pieces
are intended to assume carefully straking them to remove unnecessary creases
and puckers. The shaping moulds with the pieces on them are then placed in
dies and pressure is applied to fix the shape; the exposed ragged edges are then
trimmed. So soon as the pieces are known to be sett, which depends very much
upon the thickness and toughness of the hide, the mould with shaped portion of
the hide is removed from the die and exposed to currents of warm air until
thoroughly dry, most of the moisture having been expelled by the pressure. The
dry shaped articles on or off the moulds are then coated with or immersed in
linseed oil to render them impervious to damp which oil by after exposure of
the pieces becomes oxidysed and comparatively day and should a slight tackiness
be felt, a slight scraping of the surface and a further exposure will ensure com-
plete drying.
The pieces, preferably still on the moulds, are replaced in the die and any
swelling that may have happened be removed by pressure.
The pieces can then be removed from the moulds and be stored for making
up as desired into travelling trunks or bags, as before explained.
By way of example, I will describe the moulding of the bottom of a travelling
trunk. I take a raw hide and cut say, the centre out, this being the stoutest
portion and particularly suited for a trunk bottom, this after the preliminary
soaking and cleansing operation 1 stretch over a mould and strake the extended
edges down the sides of the mould, so that the intended bottom becomes, when
inverted, of dish shape which is afterwards fixed by the pressure when placed
in the die ready for the trimmer and waterproofing as the after or completion
process.
The pieces for the sides and ends of the trunk are similarly treated and pre-

page_text: pared with overhanging lips where required so that after placing the several
pieces in position, or by first punching holes in them where vets have to be
placed they can be secured together and the lids hinged on as found convenient.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is..
The process of soaking roughly shaped pieces of raw hides in a water charged
revolving drum straking the same on moulds, subjecting the moulded pieces to
pressure to expel moisture, drying by currents of warm air, immersion in a
drying oil, exposing for oxydation and a final pressure ready for use as parts of
travelling trunks, bags, and the like, as specified
