PROVISIONAL SPECIFICATION.
Improvements in Means Employed in Preventing the Inhalation of
Dust by Workpeople in Various Trades, Excepting that of the
Manufacture of China and Earthenware.
I, WILLIAM HALES TURNER of Chell Lodge, Tunstall in the County of Stafford,
Earthenware Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in means employed in preventing
the inhalation of dust by workpeople in various trades excepting that of the manufac-
ture of china and earthenware.
For this purpose, where possible, I enclose that portion of the bench, table,
machine or apparatus where the dust is produced or where it mostly exists, and I,
in some cases, form the said enclosure either partially or wholly of glass, so as to
enable the workman to see the course of the work and with an opening or openings to
enable the workman to introduce the work and, if necessary, his hands, to enable him
to manipulate the work or tools. In a convenient position I place a pipe supplied
with a forced air current and with a nozzle or directing orifice, so arranged as to
blow the dust away from the workpeople and towards a box, channel. or orifice
connected with a pipe or chamber to which a powerful exhaust is applied.
In cases where it is impossible or difficult to box-in or enclose the bench, table,
machine, or apparatus, or any part thereof, I employ a pipe, nozzle, or conductor
supplied with a forced air current and so directed as to blow the dust away from
the work people and towards a box, pipe, or opening communicating with an exhaust.
In any case the dust drawn off is collected in a suitable box or enclosure from
which it is removed from time to time as may be required.

COMPLETE SPECIFICATION.
Improvements in Means Employed in Preventing the Inhalation of
Dust by Workpeople in Various Trades, Excepting that of the
Manufacture of China and Earthenware.
I, WILLIAM HALES TURNER of Chell Lodge, Tunstall, in the County of Stafford,
Earthenware Manufacturer, 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 invention has for its object improvements in means employed in preventing
the inhalation of dust, foul air and gas by workpeople in various trades, excepting
that of the manufacture of china and earthenware.
For this purpose, where possible, such for instance as in machinery or apparatus
employed in the dry grinding of metal or other material, I enclose that portion of the
bench, table, machine, or apparatus, where the dust is produced or where it mostly
exists, and I, in some cases, form the said enclosure either partially or almost entirely
of glass, mounted in a suitably shaped frame, so as to enable the operative to see the
course of the work, and I also form such enclosure with an opening or openings.to
...

page_text: enable the operative to introduce the work, and, if necessary, his hands, for the
purpose of manipulating either the work, or tools, or both. In a convenient position,
exterior of said box or enclosure, and so as not to interfere with the movements of the
operative, 1 place a pipe supplied with a forced air current, and with one or more
nozzles or directing orifices, so arranged and directed as to blow the dust away from
the workpeople and towards or into the said box or enclosure, which latter is connected
with a pipe or chamber, to which a powerful exhaust is applied, one or more boxes or
enclosures being interposed for the purpose of permitting the dust to settle therein
as it is conveyed by the exhaust, and from which the collected dust may from time to
time be removed as may be required. In order to facilitate the settlement of the dust
in such boxes or enclosures, one or more diaphragms or screens may be arranged
therein, which, whilst permitting a free passage for the air, will act to intercept and
throw down the dust.
For
In cases where it is impossible or difficult to box in or enclose the bench, tablo,
machine, or apparatus, or any part thereof, I employ a pipe or conductor supplied
with a forced air current, and fitted with one or more nozzles or directing orifices,
which are so directed as to blow the dust, foul air or gas away from the workpeoplo
and towards a box, pipe, or opening to which a powerful exhaust is applied, such box,
pipe or opening being placed in as close proximity as possible to that part of tho
machine or apparatus where the dust is produced or where it mostly exists.
instance, in looms in which yarns having a considerable amount of dressing are
employed, I place one or more blast pipes or conductors in the front of the loom, as
near as convenient to the operative, and another or others in convenient position over
the warp, and having the nozzles or orifices directed so as to blow the dust away
from the operative towards the orifices of the boxes, enclosures or. receptacles to
receive the same, and I place one or more boxes, enclosures or receptacles under the
warp, either at the front or at the back of the heddles, or at both positions, and as
near as possible to the point at which the cloth is made; such boxes or receptacles aro
provided with apertures suitably placed to receive and collect the dust, and they are
connected with an exhaust, so as to draw away the dust driven towards and entering
the same.
Having described these two examples of the manner in which I carry my invention
into effect, a competent mechanic will readily apply my invention to other classes of
machinery, apparatus, work bench, or table."
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Enclosing or partially enclosing that part of a bench, table, machine, or apparatus,
where the dust is produced or where it mostly exists, with a covering provided with
apertures for the introduction and removal of the work, tools, and if necessary, the
hands of the operative, and combining therewith a blast pipe, so arranged as to blow
the dust away from the operative and towards the said covering or enclosure, and
connecting the latter with a powerful exhaust, and with a dust intercepting chamber
or chambers, from which the dust is removed from time to time, substantially as
herein described and for the purpose stated.
2. In means employed in preventing the inhalation of dust by workpeople in various
trades, excepting that of the manufacture of China and earthenware, the employment
of a pipe or pipes supplied with a forced air current, so directed as to blow the dust
away from the operative, and one or more boxes or receptacles placed in convenient
position to receive the dust and connected with a powerful exhaust, and with one or
more dust intercepting and collecting chambers, substantially as herein described.
3. In means employed. in preventing the inhalation of dust by workpeople in
various trades, excepting that of the manufacture of china and earthenware, the

page_text: combination of one or more air blast pipes, so directed as to blow the dust away
from the operative, and of one or more boxes, enclosures or receptacles connected
with a powerful exhaust to draw off the dust, substantially as herein described.
