Improvements in Apparatus connected with Exhaust-fans for
Carrying Away Chips, Shavings, Dust, and the like from
various Machines.
We, GEORGE EMERSON BODGE, of Northampton, Expert on Edge Finishing
Machines, SAMUEL NELSON CORTHELL, of Northampton, Mechanical Expert,
and NATHAN ELLSWORTH REED, Managing Director of The Vose Company,
Limited, Broad Street House, New Broad Street, in the City of London, do
hereby declare the nature of this invention to be as follows:-
Our invention is designed to provide means whereby the chips, shavings or
other cuttings, dust or the like from boot-edge trimmers and various other
machines will be carried away by the aid of an exhaust-fan in a more efficient.
manner than heretofore, so as to obviate the inconvenience and injury to the health
of the operatives which would otherwise result.
For carrying away the cuttings and dust from such machines, it has been
customary to mount upon or in proximity to the machine a shield, casing or hood
which wholly or partially surrounds the operating part or parts of the machine,
and which is connected, by a passage opening into the said shield, casing or
hood at or near the top thereof, with a pipe communicating with an exhaust-fan,
so that the chips or shavings and dust produced by the cutters or the like
will be drawn or sucked into the said passage and will pass through the exhaust-
fan to the collector or "dump."
In apparatus so constructed, some of the chips or shavings and dust frequently
fail to be influenced by the current of air entering the said passage, and conse-
quently fall upon the lower parts of the machine or upon the floor or other
platform on which the machine is mounted.
But by our invention, we obviate this inconvenience, by making the apparatus
with an upper suction-passage and also with one or more lower suction-passages
for conducting the chips or shavings and dust into the pipe connected with the
exhaust-fan, so that any chips or shavings and dust that are not caught by the
air-current entering the upper passage will be caught and carried away by
the current or currents of air entering the lower passage or passages.
We find it advantageous, in some instances, to provide the lower passage or
passages with a grating or the like extending across or over the opening thereof
so as to prevent the falling of larger objects into the said passage or passages.
The upper and lower suction-passages are connected with the exhaust-fan by a
common-pipe, or, if desired, they may be connected therewith by separate pipes.

Improvements in Apparatus connected with Exhaust-fans for
Carrying Away Chips, Shavings, Dust, and the like from
various Machines.
We, GEORGE EMERSON BODGE, of Northampton, Expert on Edge Finishing
Machines, SAMUEL NELSON CORTHELL, of Northampton, Mechanical Expert,.
and NATHAN ELLSWORTH REED, Managing Director of The Vose Company,
Limited, Broad Street House, New Broad Street, in the City 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 following
statement:-
Our invention is designed to provide means whereby the chips, shavings or
other cuttings, dust or the like from boot-edge trimmers and various other
machines will be carried away by the aid of an exhaust-fan in a more efficient
manner than heretofore, so as to obviate the inconvenience and injury to the
health of the operatives which would otherwise result.
For carrying away the cuttings and dust from such machines, it has been
customary to mount upon or in proximity to the machine a shield, casing or hood
which wholly or partially surrounds the operating part or parts of the machine, and
which is connected, by a passage opening into the said shield, casing or hool at or
near the top thereof, with a pipe communicating with an exhaust-fan, so that
the chips or shavings and dust produced by the cutters or the like will be drawn
or sucked into the said passage and will pass through the exhaust-fan to the
collector or "dump."
In apparatus so constructed, some of the chips or shavings and dust frequently
fail to be influenced by the current of air entering the said passage, and cou-
sequently fall upon the lower parts of the machine or upon the floor or other
platform on which the machine is mounted.
But by our invention, we obviate this inconvenience, by making the apparatus
with an upper suction-passage and also with one or more lower suction-passages
for conducting the chips or shavings and dust into the pipe connected with the
exhaust-fan, so that any chips or shavings and dust that are not caught by the
air-current entering the upper passage, will be caught and carried away by
the current or currents of air entering the lower passage or passages.
We find it advantageous, in some instances, to provide the lower passage or
passages with a grating or the like extending across or over the opening
thereof so as to prevent the falling of larger objects into the said passage or
passages.
The upper and lower suction-passages are connected with the exhaust-fan by
a common-pipe, or, if desired, they may be connected therewith by separate pipes.
In the accompanying drawing we have shown how our said invention may be
conveniently and advantageously carried into practice :-
Figure 1 is a side elevation, partly in vertical section, and
Figure 2 a horizontal section on the line a, a, Figure 1, showing one form of our
improved apparatus designed for use with a boot-edge trimmer.
A is the shield, casing or hood, which has one of its side walls A' cut away
to conform to the machine with which it is to be used. Within the said casing
is a partition B forming, with the top and the rear and side walls thereof, the
upper 'suction-passage C, which opens beneath the lip D at the front end of the
casing A, and is in communication through the suction-pipe or exhaust-pipe E,
with the fan or other exhausting apparatus. This exhaust-pipe is also in com-
munication with a lower suction-passage F opening into the casing A at the

page_text: bottom and near the rear end thereof, the aperture being, by preference, protected
by a grating G to prevent the falling of large objects into the exhaust-pipe.
Some of the dust, chips and the like rising from the working parts of the
machine will be drawn as usual into and through the upper suction-passage C,
whilst any dust, chips or the like that may not be drawn into that passage will be
drawn into and through the lower suction-passage F directly into the exhaust-
pipe E. The operatives will, therefore, be much more effectually protected thau
heretofore against the inconveniences and injury to which they are liable by reason.
of the dust, chips or cuttings being directed towards them or falling upon the work
or upon the machine.
It is obvious that the construction of the shield, casing or hood may be modified.
to suit various forms of machines, and that, if desired, more than one lower suction-
passage can be provided.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
An apparatus for the purposes specified, wherein the shield, casing or bood is.
provided not only with the usual upper suction-passage, but also with one or more
lower suction-passages adapted, like the upper suction-passage, to be put in.
communication with a suitable exhausting apparatus, substantially as hereinbefore
described.
