PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at the
Office of the Commissioners of Patents on the 4th October 1876.
JOSEPH JULIUS SACHS, of New Barns, Barrow-in-Furness, in the County of
Lancaster, Manufacturer. and Chemist. "AN IMPROVED APPARATUS FOR USE IN
TREATING ANIMAL AND VEGETABLE SUBSTANCES IN ORDER TO FACILITATE THE
IMPREGNATION OR THE EXHAUSTION THEREOF OF AERIFORM OR OTHER FLUID."
The substances to be operated upon are placed in a main vessel made sufficiently
strong to resist required internal or external pressure, and with a moveable cover,
which when applied is capable of being held securely in position air-tight. By the
side of this main vessel and in communication with it near its upper and lower
part I apply another chamber formed of glass, or with glass fitted therein to
facilitate inspection of fluids contained in the main vessel either as to the heighth
thereof, or through a loose cover or other opening the strength or other conditions
of the same, whether aeriform or otherwise, or for the purpose of testing the action
of the fluid on samples of the substances to be treated. The upper part of this
main vessel is by a stop-cock and pipe in connection with the cylinder of a pump
and a changeable valve arrangement by which the pump may be caused to act
either to exhaust air or other fluid from the main vessel or to force it therein. The
lower part of this main vessel is by taps, or valves, or other pipes capable of being
brought into communication with other reservoirs or sources of supply, so that
when by the pump described the substances placed in the main vessel have been
DQ31

with one or other of such reservoirs other fluid or fluids may be allowed to flow into
and the more readily impregnate such matters. These fluids may be forced in under
pressure if desired, and when impregnation has been effected to the extent desired
the surplus fluid may be allowed to flow out by another passage, and the flowing
out may be facilitated by the injection of air or aeriform fluid by the pump as
described. A vacuum or pressure gauge may be applied to indicate the extent of
vacuum or pressure attained.
In some cases the fluids may be admitted into the interior of the main vessel in
finely divided streams through fine perforations either from the sides or through a
cylinder in the centre or other part, through which the fluid will flow and be
distributed amongst the contained substances; and in some cases I employ a
moveable diaphragm to act on the materials in the main vessel for the compression
of them, such diaphragm having a shaft passing through suitable packing in the
cover of this vessel, and being there acted upon by a screw or clamping means.
