I, WILLIAM BARRACLOUGH of Providence Foundry Stanningley Yorkshire Iron-
founder do hereby declare the nature of this invention to be as follows:-
It relates to improvements in machines which are employed for Dry Grinding,
Cutting or Polishing purposes, wherein the grinding, cutting and polishing is
performed with revolving Emery (or other Composite Cutting) wheels, Stones or
Saws, or with toothed metal wheels, or wheels covered with leather, lead, cloth,
Bristles, Hair, Fibre or other (suitable) soft, material, operating in conjunction with
rapid revolving machinery; and the objects of these my improvements are,
First, to confine within suitable receptacles, the dust, grit and fume which are
evolved during the processes of dry grinding cutting or polishing (of metal or other
substances) and discharge the same into, and through, an exhaust chamber and flue,
and thereby prevent the inhalation of the dust and fume by the person using the
machine.
Second, to prevent particles of grit, or other injurious substances, being discharged
from the revolving wheel into the face of the person using the machine.
Third, to protect the spindles and other working parts of the machine, by
coverings and casings, from contact with the dust and grit which are given off by the
cutting and other wheels of the machine.
Fourth, to provide one or more suitable receptacles in each machine for the deposit
and accumulation of the heavier particles of grit and dust which are produced during
the cutting, grinding or polishing process and afford easy facilities for the removal of
such deposits.
Fifth, to afford means for conveniently angleing the articles which are being ground,
cut or polished.
Sixth, to render the spindles of such machines more easily adjustable within their
journals than they have hitherto been.
I attain these objects by the mechanism illustrated in the accompanying diagrams
in which
Fig. 1 is a perspective view of the entire machine shewing it fitted with composite
(Emery) wheel or Grindstone and driving belts.
Fig. 2 is a perspective view of the machine fitted with toothed cutting wheel, the

page_text: upper (side) plate removed from the cutting wheel Hopper, the Hood of said wheel
thrown back, door removed from spindle chamber, oil cup cover thrown back &c.
Fig. 3 is a perspective view of the machine fitted with a toothed cutting wheel and
driving belts the front plates of (Wheel's) Hopper and dust chamber are removed and
the Hood thrown back from the wheel. The positions of the two driving belts in
this illustration are different to those shewn in Figs. 1 and 2.
Fig. 4 is a perspective view of the machine, fitted with grinding wheel and driving
belts, with Hood thrown back from wheel and shewing cover plate removed from the
Fan box and exhaust in addition to those of the hopper and dust chamber.
Fig. 5 is a perspective view of the machine, similar to the one shewn in Fig. 4 but
seen from the opposite end of machine and shewing it fitted with Grinding wheel and
driving belts also shewing side door and cover plate removed from chamber occupied
by the Fan" Spindle.
Fig. 6 is perspective view of the machine fitted with Grinding wheel and driving
belts but with side door removed from ("Fan") spindle chamber; the pulley for
driving the "Fan "being, in this illustration outside the said chamber.
Fig. 7 is a perspective view of the machine (as seen from the back) fitted with
circular saw and driving belts, the driving pulley for "Fan” being outside the spindle
chamber.
Fig. 8 is a perspective view of the machine (as seen from the back) fitted with
polishing wheel and driving belts, the latter being applied similarly to those in
Figs. 3. 4 and 5.
Fig. 9 is an end elevation of the machine shewing plates removed from Hopper and
dust chamber.
Fig. 10 is a plan of the machine at A B Fig. 9, the two chambers, one for the
"Fan" and the other for its spindle and driving gear.
Fig. 11 is a vertical section of the machine at C. D. Fig. 10, shewing the two
chambers, one occupied by the "Fan" and the other by its driving gear & spindle.
Fig. 12 is a perspective view of the machine, fitted with an adjustable shelf or bench
for supporting and angleing purposes.
Fig. 13 is a perspective view of an adjustable Rest shewn fitted upon a fragment of
the Hopper.
Fig. 14 is a perspective view of an adjustable Rest slightly different in construction
to the one shewn in Fig. 13, but shewing the slots for adjustment of the Rest to suit
small or large wheels, and internal grooves, or slots, for suction and clearing purposes.
Fig. 15 is a perspective view of a loose adjustable nose piece for Hood (a fragment
of which is also shewn with upright flange and slots for purposes of vertically adjust-
ing the loose nose piece).
Fig. 16 is a perspective view of cover plate for "Fan" box and exhaust flue
shewing the sloping shed" for preventing dust entering the "Fan" box & exhaust
by means of gravitation, direct precipitation or any other means than suction.
Similar letters refer to similar parts throughout the several illustrations.
The pedestal, marked Z, represents the body of the machine, and is divided into two
(or more) principal compartments, E and F. The spindle and other driving gear for
the cutting or polishing wheel, is fitted externally (and preferably) on the top of the
pedestal Z.
The compartment marked E is occupied by the "Fan" G, and the compartment
marked F is occupied by the spindle, H, and other driving gear for the "Fan."
The grinding, cutting, or polishing wheel J is fixed, usually and preferably to the
end of the spindle K and is revolved by motive power communicated by the driving
belt L.
The Hopper M is intended to enclose partially the grinding, cutting or polishing
wheel J which is also further enclosed within a hood N the said hood being hinged to
the hopper M. The lower part of this hopper opens into the chamber where the
fan, G, is in its turn, enclosed within a cavity or box covered by the plate O and
extended, when necessary, by the exhaust pipe P, the plate O being provided with a
small aperture Q for the purposes of suction, into and at which aperture, the fumes
::

page_text: and light particles of dust are drawn from the chamber. E by the suction resulting
from the revolving "Fan" and these fumes and dust are thence expelled by the blast
from the "Fan" through the exhaust pipe P.
The framework, S, forms part of the hopper frame and supports the shelf T which is
pivotted at U to the said framework and is sloped or angled up or down by means of
the wheel W and screw rod V.
The Hood N is provided with a separate and adjustable nose piece Y and a thumb
screw X for rendering the hood adjustable to the varying dimensions of wheels as the
latter wear away with use.
The pivotted shelf T may be attached to the Broadside framework of the Hopper as
shewn in Fig. 12 so that the broadside of the wheel may supply the rubbing or
grinding surface, or it may be attached to one end of the Hopper so that the outside
periphery of the wheel may supply the friction surface for grinding, cutting or
polishing.
The spindles H and K are (preferably but not necessarily) tapered for purposes of
easy adjustment and the brackets (one or more) which support them (or the base plates
upon which certain of the brackets are fitted) being furnished with oblong bolt holes
to enable the brackets to be placed nearer together or wider apart according as the
Journals or Bushes require.
The Wheels marked J may be either grindstones Emery wheels, metal faced cutting
wheels, or Composite grit, cutting wheels other than those called "Emery" wheels,
or saws, or they may be Polishing wheels with surfaces of leather, lead or other
suitable materials.
The driving Pulley, A2, which is fixed upon the spindle of the "Fan "outside the
pedestal, Z, as shown in Figs. 1. 2. 6. 7. 10. 11 and 12 illustrates the way in which I
prefer to drive the "Fan" nevertheless if it should be found desirable to drive the
Fan" in a different manner its driving pulley may be fixed upon the "Fan" Spindle
within (and not outside) the chamber F, as shewn by B2 in Fig. 5 and in this latter
case the pulley B² and "Fan" Spindle would be mutually revolved by the driving
belt R as shewn in Figs. 3. 4. 5 and 8. This latter plan is objectionable as the dust
and grit are in this way liable to get within the chamber F and injure the working
parts of the machine.
Although (for purposes of simplicity and clearness) I have confined the foregoing
description to dry grinding, Cutting or Polishing machines which have only one such
grinding, cutting or polishing wheel to each machine, I do not wish it to be understood
that I limit my invention to machines which have only one such wheel, but desire to
state that I contemplate making them variously with one, two or oven more than two
such wheels, and their associate appliances for dust and fume exhaustion (and other
useful and beneficial purposes herein described) to each machine.
I am aware that prior to my invention, tapered or conical spindles have been used
in connection with machinery of various kinds, but, I have never known such double
tapered or double conical spindles, as herein described and shewn, to have been applied
to Emery wheel (or such like) dry grinding machines.
1 am also aware that, prior to this application, ilust exhausting appliances have
been combined with Emery wheel dry grinding machines, but I have never known
such dust and fume exhausting appliances, as herein described and drawn to have
been employed.
It will therefore be understood that I do not claim the use of conical spindles or the
combination of dust and fume exhausting appliances with Emery wheel (or such like)
dry grinding machines, broadly, as my invention.

page_text: I, WILLIAM BARRACLOUGH of Providence Foundry, Stanningley in the County of
York Ironfounder 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 :-
It relates to improvements in machines which are employed for dry grinding, cutting
or polishing purposes, wherein the grinding, cutting and polishing is performed with
revolving emery (or other composite cutting) wheels, stones or saws or with toothed
metal wheels or wheels covered with leather, lead, cloth, bristles, hair, fibre or other
(suitable) soft material operating in conjunction with rapid revolving machinery and
the objects of these my improvements are,
First, to confine, within suitable receptacles, the dust, grit and fume which are
evolved during the process of dry grinding, polishing or cutting (of metal or other sub-
stances) and discharge the same into, and through, an exhaust flue, and thereby
prevent the inhalation of the dust and fume by the person using the machine.
Second, to prevent particles of grit, or other injurious substances, being discharged
from the revolving wheel into the face of the person using the machine.
Third, to protect the spindles and other working parts of the machine, by coverings
and casings, from contact with the dust and grit given off by the cutting and other
wheels of the machine.
Fourth, to provide (one or more) suitable receptacles in each machine for the deposit
and accumulation of the heavier particles of grit and dust which are produced during
the cutting grinding or polishing process and afford easy facilities for the removal of
such deposits.
Fifth, to afford means for conveniently angleing the articles which are being
ground, cut or polished.
Sixth, to render the spindles of such machines more easily adjustable within their
journals than they have hitherto been.
I obtain these objects by the mechanism illustrated in the diagrams, accompanying
the provisional specification.

chambers. one occupied by the "Fan" and the other by its driving gear and spindle.
Fig. 12. is a perspective view of the machine fitted with an adjustable, shelf or bench
for supporting and angleing purposes.
Fig. 13. is a perspective view of an adjustable "Rest" shewn fitted upon a fragment
of the Hopper.
Fig. 14. is a perspective view of an adjustable "Rest" slightly different in construc-
tion to the one shewn in Fig. 13. but shewing the slots for adjustment of the Rest"
to suit small or large wheels, and internal grooves or slots, for suction and clearing
purposes.
Fig. 15. is a perspective view of a loose adjustable, nose piece for Hood (a fragment
of which is also shewn with upright flange and slots for purposes of vertically adjusting
the loose nose piece).
Fig. 16. is a perspective view of cover plate for "Fan" Box and exhaust flue shewing
the sloping "shed for preventing dust entering the "Fan" box and exhaust by
means of gravitation, direct precipitation or any other means than suction. Similar
letters refer to similar parts throughout the several illustrations.
The pedestal, marked Z, represents the body of the machine, and is divided into (two
or more) principal compartments, E and F, the spindle and other driving gear for the
cutting or polishing wheel, is fitted externally (and preferably) on the top of the
pedestal Z.
The compartment marked, E, is occupied by the "Fan," G, and the compartment
marked, F, is occupied by the spindle, H and other driving gear for the "Fan."
The grinding, cutting, or polishing, wheels J are fixed, usually and preferably to one,
either or both ends of the spindle K, and are revolved by motive power communicated
by the driving belt L.
The Hopper M is intended to enclose, partially, the grinding, cutting or polishing
wheel, which is also further enclosed within a Hood N, the said Hood being hinged
to the Hopper M. The lower part of this Hopper opens into the chamber E where the
Fan," G, is, in its turn, enclosed within a cavity or box covered by the plate O and
extended, when necessary, by the exhaust pipe P. the plate O being provided with a
small aperture Q for the purposes of suction, into and at which aperture, the fumes and
light particles of dust are drawn from the chamber E by the suction resulting from the
revolving Fan," and these fumes and dust are thence expelled by the blast from the
"Fan "through the exhaust pipe P.
The framework, S, forms part of the Hopper frame and supports the shelf T which
is pivotted at U t.) the said framework and is sloped or angled up or down by means
of the wheel W and screw rod V.
The Hood N is provided with a separate and adjustable nose piece, Y, and a thumb

page_text: screw X for rendering the Hood adjustable to the varying dimensions of wheels as the
latter wear away with use.
The pivotted shelf T may be attached to the broadside framework of the Hopper as
shewn in Fig. 12, so that the broadside of the wheel may supply the rubbing or grind-
ing surface, or it may be attached to one end of the Hopper so that the outside
periphery of the wheel may supply the friction surface for grinding, cutting or
polishing.
The spindles H and K are, (preferably but not necessarily) tapered for purposes of
easy adjustment, and the brackets (one or more) which support them (or the base plates
upon which certain of the brackets are fitted) being furnished with oblong bolt holes
to enable the brackets to be placed nearer together or wider apart according as the
journals or Bushes require.
::
The wheels marked J may be either grindstones, Emery wheels, metal faced cutting
wheels or composite, grit, cutting wheels, other than those cailed Emery" wheels, or
saws, or they may he Polishing wheels with surfaces of leather, lead, or other suitable
materials.
The driving pulley A³, which is fixed upon the spindle of the "Fan" outside the
pedestal Z, as shewn in Figures 1, 2, 6, 7, 10, 11 and 12, illustrate the way in which
I prefer to drive the "Fan," nevertheless if it should be found desirable to drive the
"Fan" in a different manner, its driving pulley may be fixed upon the "Fan" spindle
within, (and not outside) the chamber F as shewn by B in Figure 5, and in this latter
case the pulley B³ and "Fan" spindle would be mutually revolved by the driving belt
R, as shewn in Figures, 3, 4, 5 and 8. This latter plan is somewhat objectionable, as
the dust and grit are, in this way liable to get within the chamber F and injure the
working parts of the machine.
The oil cups, C, are provided with covers, which are marked D², for excluding the
dust and grit.
Although, (for purposes of simplicity and clearness) I have confined the foregoing
description to dry grinding, cutting or polishing machines which have only one such
grinding, cutting or polishing wheel to each machine, I do not wish it to be understood
that I limit my invention to machines which have only one such wheel, but desire to
state that I contemplate making them variously, with one, two, or even more than two
such wheels and their associate appliances for dust, and fume exhaustion (and other
beneficial purposes herein detailed) to each machine.
I am aware that, prior to my invention screw elevating tables have been used for
angleing purposes in connection with Emery wheel grinding machines, also that such
machines have been made with dust exhausting appliances for Emery wheels fitted
centrally upon the spindle thereof in contradistinction to being fitted upon one or other
extreme end of it: I am also aware that single and double conical spindles have been
used for various kinds of machines it will therefore be understood that I do not claim
such broadly as my invention..
Having now particularly described and ascertained the nature of my Invention and
in what manner the same is to be performed, I declare that what I claim is,
In an Emery wheel, or such like, grinding, cutting, and polishing, machine, the
combination therewith of mechanical parts, for dust exhaustion and other purposes, all
substantially as herein described and shewn.
Dated this 13th day of August. 1887.
