IMPROVEMENTS IN OR APPLICABLE TO GRINDING APPARATUS
Year: 1880

page_text: LETTERS PATENT to Richard Russell Gubbins, of 17, Park Road, New Cross,
in the County of Kent, Gentleman, for an Invention of "IMPROVEMENTS IN
OR APPLICABLE TO GRINDING APPARATUS."
PROVISIONAL SPECIFICATION left by the said Richard Russell Gubbins at
the Office of the Commissioners of Patents on the 20th November 1880.
RICHARD RUSSELL GUBBINS, of 17, Park Road, New Cross, in the County of
Kent, Gentleman. "IMPROVEMENTS IN OR APPLICABLE TO GRINDING APPARATUS."
This Invention relates to certain improvements in or applicable to emery or
other grinder apparatus, the object being to provide means for gathering the
dust resulting from the grinding operation so as to avoid its dispersion in the
atmosphere.
Upon the shaft which carries the grinding wheel or wheels is mounted a rotary
exhaust fan, communicating by the usual side opening of the casing with casings or
troughs wherein work the grinding wheels.
The action of the fan draws into and from the casings or troughs containing the
grinding wheels, through the said pipe or pipes, all dust or particles resulting from
the abrasion of the ground material and the grinding wheel, and discharges the
same into any place away from the other machinery and operators, such as a water
tank or a forge fire, for instance.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Richard Russell Gubbins in the Great Seal Patent Office on the

Fig. 1 is a front view of grinding apparatus constructed and fitted according to
this Invention.
Fig. 2 is a plan.

A is the grinding wheels' shaft mounted in bearings B of the framing; C is the
casing of the rotary exhaust fan communicating by side opening of fan casing
at C with the pipe or trunk extension D, which leads by horizontal trunk D¹ to
the casings or troughs E wherein work the grinding wheels F. The wheel
casings E are fitted, as shown, with double guards or covers for increasing the
vacuum or exhaust effect; G is a guard and rest serving for the holding to the
grinding wheel of the work in hand. The arrows show the direction of the induced
or vacuum current through the apparatus, and same discharges from the opening H
or any desirable extension thereof to carry away the dust or particles resulting
from the abrasion of the material under the grinding operation to any required
point; I is the driving pulley on shaft A, but may be fast and loose pulley, if
desired. The mounting of the grinding wheels on the shaft A is by side holding
discs in substantially ordinary manner, as shown.
Having now described the nature and particulars of the said Invention in such
wise that the same may be readily carried into practical effect, I claim,―
In grinding apparatus the casing E of the wheel in cominunication with air
trunk D and extension D leading to the fan case, as and for the purpose
substantially as herein set forth and shown by the Figures of the accompanying
Drawings.
In witness whereof, I, the said Richard Russell Gubbins have hereunto set
my hand and seal, this Eighteenth day of May, in the year of our Lord
One thousand eight hundred and eighty one.
