page_text: I, WILLIAM RIGG, of Swaine Street, Bradford, in the county of York, Designer
of Patterns for Textile Fabrics do hereby declare the nature of the said invention
for "IMPROVEMENTS IN APPARATUS EMPLOYED IN SORTING CERTAIN KINDS OF
WOOL, AND IN THE MANIPULATION OF OTHER NOXIOUS SUBSTANCES
to be as
follows:-
"
The object of my invention is to prevent the dispersion into the atmosphere of
poisonous dust or vapors which arise during the sorting or handling of certain
kinds of wool, hair or other like substances, during the pulverization or mixing of
poisonous or offensive chemicals or drugs, or during the working in any way of
substances giving off poisonous dust, hairs or vapor.
To carry out my invention I place a clear glass screen fixed in a suitable frame-
work, and working upon hinges, or in slides, between the operator and the
substance being manipulated, but allowing such substance to be perfectly visible.
The most suitable position for this screen is at an angle, sloping upwards from the
operator, to the wall, or other support to which it may be attached at the back.
The front of the screen fits air-tight against, or upon the top of the table upon
which the manipulation is to take place, and the two sides, and back of such screen
are also closed in air-tight.
A framework of rails, or wire trellis, is supported at a short distance above the
top surface of the table, allowing the dust caused during the manipulation to fall
or to be carried through the interstices thereof.
A vertical pipe or spout opening to the level of the top of the table, and under
the rails or wire trellis bereinbefore mentioned communicates with any suitable
arrangement such as an exhaust fan whereby the dust or vapour as it is formed
will be drawn off and carried away. One or two holes are provided in the glass
screen or in the front of the framework supporting such screen, into which holes
are fitted flexible macintosh or elastic dust proof sleeves fitting tightly to the arms
or wrists of the operator, when his arms are passed into the said holes and during

page_text: the manipulation of the substance upon the table. These sleeves are if necessary
provided with gloves attached to their extremities. As these sleeves are attached
air-tight round the edges of the holes and as also owing to their elasticity they fit
air-tight to the operator's arms or wrists, without preventing the free movement of
the same, it will be seen, that during the manipulation of a substance upon the
table, no dust or vapor arising from such substance can escape into the room, being
prevented from doing so by the glass screen and its surroundings, and such dust or
vapour will therefore be carried off through the pipe or spout by means of the
current of air produced by the exhaust fan herein before mentioned.

page_text: I WILLIAM RIGG of Swaine Street, Bradford, in the county of York, Designer
of Patterns for Textile Fabrics, do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS EMPLOYED IN SORTING CERTAIN KINDS OF WOOL
AND IN THE MANIPULATION OF OTHER NOXIOUS SUBSTANCES" and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The object of my invention is to prevent the dispersion into the atmosphere of
poisonous dust or vapours which arise during the sorting or handling of certain
kinds of wool, hair or other like substances, during the pulverization or mixing of
poisonous or offensive chemicals or drugs, or during the working in any way of
substances giving off poisonous dust, hairs, or vapour.
To carry out my invention I employ a clear glass screen fixed in a suitable
framework, and working upon hinges, or in slides between the operator and the
substance being manipulated, but allowing such substance to be perfectly visible.
The most suitable position for this screen is at an anglo sloping upwards from the
operator to the wall or other support to which it may be attached at the back.
The front of the screen fits air tight against or upon the top of the table upon
which the manipulation is to take place, and the two sides and back of such screen
are also closed in airtight.
A frame-work of rails or wire trellis is supported at a short distance above the
top surface of the table, allowing the dust caused during the manipulation to fall
or to be carried through the interstices thereof.
A vertical pipe or spout opening to the level of the top of the table, and under
the rails or wire trellis berein before mentioned, communicates with any suitable
arrangement such as an exhaust fan, whereby the dust or vapour as it is formed
will be drawn off and carried away. One or two holes are provided in the glass
screen, or in the front of the framework supporting such screen, into which holes
are fitted flexible macintosh or elastic dust proof sleeves which can fit tightly to
the arms or wrists of the operator when his arms are passed into the said holes
during the manipulation of the substance upon the table. These sleeves are if
necessary provided with gloves attached to their extremities. As these sleeves are
attached air tight round the edges of the holes, and as also, owing to their
elasticity, they fit air tight to the operator's arms or wrists, without preventing
the free movement of the same, it will be seen, that during the manipulation of a
substance upon the table, no dust or vapour arising from such substance can escape
into the room, being prevented from doing so by the glass screen and its
surroundings, and such dust or vapour will therefore be carried off through the
pipe or spout, by means of the current of air produced by the exhaust fan
herein before mentioned.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing, in which figure 1 represents

page_text: a transverse section of an apparatus constructed according to my invention, and
figure 2 a front elevation of the same.
Similar letters refer to similar parts in both the figures.
The wool to be opened out or sorted or the substance to be manipulated is
passed through a door D, which may have an opening through an outer wall, or
into another room than that in which my improved apparatus is fixed.
The wool or other substance to be manipulated is placed upon the grating or
wire trellis E, and the door D, is then closed and secured. An exhaust fan or its
equivalent is connected with the pipe F, and draws away all dust, hairs or noxious
vapours which fall or are drawn through the grating or trellis E.
A, is the glass placed in the frame or lid B, which closes as nearly as possible air
tight upon the case K, which surrounds the table on four sides; the glass prevents
any dust, hairs or noxious vapours from rising and being diffused in the room, but
at the same time allows the substance being manipulated to be perfectly visible.
G, G, are the two holes in the front of the case K, fitted with elastic or dust
proof sleeves H, and if necessary with gloves in addition to the sleeves, and as, the
sleeves fit air tight to the case K, and also to the arms or wrists of the operator,
no dust can escape from the front of the case.
:
"
By employing an apparatus of this construction bales of wool can be introduced
through the door D, and opened out or sorted without risk of any dust or vapour
arising therefrom escaping into the air breathed by the operator, and in a similar
manner the most poisonous substances may be placed upon the grating E, and
pulverized. or otherwise manipulated, without risk of the poisonous dust or vapour
escaping into the air of the room in which the apparatus is placed.
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 improved sorting or manipulating table as described, having a glass cover or
screen fitting closely to the case upon which it rests, combined with a grating or
trellis, and an exhaust fan or its equivalent for drawing off the dust or vapour,
and sleeves attached to the front of the case, with or without gloves, all
substantially as and operating in the manner described, or any mere modification
thereof.
