Improvements in the Treatment of Night Soil.
I, JABEZ ROYSTON, of 5, Cottingham Street, Attercliffe, Sheffield, in the County
of York, Brass Cleaner, 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 following statement:
The
With regard to the improved treatment of night soil, instead of greasing the
inside of the bucket as described in 16078, 1896, it would be better to use a lining
of strong paper, made to fit inside the bucket, to prevent the soil adhering to the
inside of the bucket, the buckets to be of a uniform size, and instead of mixing
over a fire as in 16078, it would be better to mix it as deposited, the mixer to press
the soil down solid, and put a layer of dried vegetable waste, mixed with a small
quantity of soot, this to be repeated at intervals. Instead of sterilising each vessel
separately, a sterilising chamber could be constructed, to contain a number of
buckets, this chamber to be heated by steam, or by a fire underneath as in a brick-
makers drying stove. If these chambers were erected in pairs, they would be
better, as in Fig. 1, a, the sterilising chamber, b the fire underneath, to sterilise
and comsume the foul gases arising from the process; c, the flue to carry away
the deodorised gases, to the chimney; f, e, pipe, for ventilating the chamber, and
conducting the foul gases underneath the fire, to be deodorised before entering the
chimney; g, the damper to stop the draft when not required. The back part of
the chamber is shown in Fig. 2; a, the chamber, b, a pipe to supply air from the
outside, and passing through the flue, so that the air for ventilating the chamber,
shall enter hot, and be distributed over the chamber by the perforated pipe c,
by products, or the condensed vapour, could be collected in a receiver attached to
the lowest part of the pipe, before entering the ashpit. When the process of
sterilisation is complete, and the fire let down, the current of air could be reversed,
and in cooling, the warm air from the first, passed through the the second chamber.
When cooled down the buckets should be removed to an air-tight store house,
Fig. 3, each bucket to be covered while removing, and the contents of the buckets
turned out, in this case ventilation will be required, but kept under control, a, the
pipe to convey any smell arising from the contents from the upper part of the
store house to the flue de damper to shut off draft when not required 6 double floor
the inner floor to be loose so that the air will arise from the bottom and mix freely
with the contents. It would be useful at times to reverse the current
making the air to pass out at one end at one time and the opposite
that it would require a pipe at each end
of the store house. It would be useful if the various currents of foul air arising
from the preparation and storage could be passed through a gas retort or some-
thing like it and kept at a red heat by a fire underneath as in Fig. 4 a the retort
or pipe conveying foul air b fire underneath to be kept at a red heat to deodorise
the foul air as it passes through the pipe before entering the chimney c the flue
to conduct the smoke from the fire to the chimney.

page_text: Having now particularly described and ascertained the nature of my improve-
ments and in what manner the same are to be performed I declare that what I
claim is:-
First. The lining of the bucket with strong paper the paper lining will allow
the contents of the bucket to be turned out leaving the inside clean.
2nd. The mixing in the closet as it is deposited with vegetable waste and soot.
3rd. The sterilising chamber as described.
