Improvements in and relating to Emery Wheel Machines for
Polishing Metal Surfaces.
1, FREDERICK JOHN ROWAN, of 121, West Regent Street, in the County of the
City of Glasgow, Engineer, do hereby declare the nature of my invention to be
as follows:-
This invention has reference to improvements in and relating to emery wheel
machines for polishing or dressing metal surfaces.
Under one arrangement the transverse spindle on which the emery wheel is
secured would be mounted in suitable bearings in a travelling open frame or
housing with protecting casing, said frame having internal screw threaded collars
or bushes which work over parallel screw threaded longitudinal spindles carried
in bearings in transverse crossheads near their ends. These spindles would be
turned simultaneously by spur pinions operated by an intermediate hand turned
wheel, and so traverse the frame carrying the emery wheel to and fro as required.
The spindle carrying the emery wheel would be shifted to and fro transversely
by a screw threaded sleeve and outer hand wheel and sleeve or equivalent appli
ances so as to bring the emery wheel to the position desired. The longitudinal
spindles would be connected at their one end to rocking levers working in bear-
ings carried by an anchoring horse shoe or like electric magnet the other end of
these levers having counterbalanced weights secured thereon. An electro motor
may be mounted on the yoke of said magnet; the spindle of emery wheel being
driven from spindle of motor by a flexible shaft either direct or through bevel or
toothed gear by a spindle parallel to movement of the emery wheel travel with
suitable connecting gearing.
Instead of two screw threaded spindles only one may be used there being two
plain surfaced guiding spindles or tubes. The electro motor may be mounted on
a trolley and drive the emery wheel spindle by a flexible shaft connection. The
cross head to which the levers are attached would or may be fitted with a joint
or hinge so as to be able to oscillate to and fro horizontally as well as vertically
on the fulcrum spindle.
Under another arrangement the longitudinal traversing movement is con-
trolled automatically. The electro motor is mounted on framing carrying the
emery wheel spindle and the latter is driven by a belt from motor spindle.
In this case one longitudinal screwed spindle would preferably be used for the
traversing movement which spindle or shaft would be fixed and an internal screw
threaded bush on emery wheel frame would be mounted on same. A belt can be
used to drive gearing for reversing travel of the emery wheel. A toothed wheel
would be fitted on the screw threaded bush and gear with a similar wheel on a

page_text: spindle on same frame; and a bevel wheel on this spindle would be in gear con-
nection with bevel wheels, and a connecting clutch would be fitted with a lever
which would be automatically operated by a kicker on longitudinal screw threaded
spindle or on the guides to put same in gear with either wheel. In this case a
three poled magnet would preferably be used.
The use of the anchoring electro magnet is to attach the machine to large
pieces of work such as a stern frame or other castings or forgings but a pillar,
standard or wall plate may be substituted for the anchoring electro magnet when
the machines are used in workshops.
It will be understood that these arrangements may be modified such as com-
bining automatic reversing of the travelling emery wheel with other arrange-
ments of motor or with belt gear from any adjacent prime moving shaft.
In some cases the machines may be driven entirely by belts without the use of
motors.
Jimprovements in and relating to Emery Wheel Machines for
Polishing Metal Surfaces.
I, FREDERICK JOHN ROWAN, of 121, West Regent Street, in the County of the
City of Glasgow, Engineer, do hereby declare the nature of my invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement in writing that is to say -
This invention has reference to improvements in and relating to emery wheel
machines for polishing or dressing metal surfaces.
And in order that my said invention and the manner of carrying same into prac-
tice may be properly understood, I have hereunto appended a sheet of explanatory
drawings in which Figure 1 is a plan view and Figure 2 a side elevation repre-
senting one arrangement of my emery wheel machine in which the travelling
frame carrying the emery wheel traverses on a screw threaded spindle. Figures 3
and 4 are end and side elevations, partly in section of a modification in which the
longitudinal traversing movement is controlled automatically, and Figure 5 is a
broken away plan view of the motor table and gearing to show the clutch
mechanism.
Referring to Figures 1 and 2.
The
Under this arrangement the transverse spindle A¹ on which the emery wheel A
is secured would be mounted in suitable bearings in a travelling open frame or
housing B with protecting casing B' said frame B being mounted on two plain
surfaced guiding spindles or tubes C carried between crosshead C¹, C².
frame B would have an internal screw threaded collar or bush which would work
over a parallel screw threaded longitudinal spindle D carried in a bearing in the
transverse, crossheads C, C³, near its ends, and this spindle 1) would be turned
by a handle D¹ and so traverse the frame B carrying the emery wheel A to and
fro as required. Instead of a single spindle D two such screw threaded spindles
may be used and be turned simultaneously by spur pinions operated by an inter
mediate hand turned wheel. The spindle A¹ carrying the emery wheel A would

page_text: be shifted to and fro transversely by a screw threaded sleeve b, and outer hand
wheel and sleeve 6, or equivalent appliances so as to bring the emery wheel A
to the position desired. Or this may be done at either end or both ends of the
framing by a transverse screw shifting the longitudinal guide over.
In this case
a single square or flat bar may be used as a guide, the screw spindle for longi-
tudinal movement being placed centrally above it; and the emery wheel spindle A¹
in this case would have no transverse motion.
Rocking levers E would be connected at their one end to the crosshead C by
a pin joint or hinge E, and be fulerumed on a transverse spindle in bear-
ings carried by an anchoring horse shoe or like electro maguet the other ends
of these levers E having counterbalanced weights 13 secured thereon. But the
counterbalance weights may be attached to cords or chains passing over pulleys
especially when a fixed standard is used instead of an electro magnet the ends of
the cords being attached to the crosshead C. An electro motor may be mounted
on the yoke of said magnet F; and the spindle A¹ of emery wheel A may be
driven from spindle of motor by a flexible shaft either direct or through bevel or
toothed gear or by a spindle parallel to movement of the emery wheel travel with
suitable connecting gearing, or the electro motor may be mounted on a trolley
and drive the emery wheel spindle A by a flexible shaft connection. In cases
where the emery wheel A has to work against curved surfaces, motion suitable
to these curved surfaces would be allowed for at the joint part E.
In the arrangement shown in Figures 3, 4, and 5, the longitudinal traversing
movement is controlled automatically. The electro motor G is mounted on fram-
ing B carrying the emery wheel spindle A' and the latter is driven by a belt Z
from motor spindle G¹.
In this case two longitudinal guide spindles C would be fitted and one longi-
tudinal screwed spindle D would preferably be used for the traversing movement,
which spindle or shaft D would be fixed and an internal screw threaded bush B²
en emery wheel frame B would be mounted on same. A toothed wheel H would
be fitted on the screw threaded bush B and gear with a similar wheel H' on a
spindle H on same frame; and a bevel wheel on this spindle H would be in
gear connection with bevel wheels, 2, and a connecting clutch would be
fitted with a lever which would be automatically operated by an ordinary
kicker on longitudinal screw threaded spindle D or on the guide spindles C to
put same in gear with either wheel or h². In this case a three poled magnet
would preferably be used for anchoring the machine.
The use of the anchoring magnet is to attach the machine to large pieces of
work such as a stern frame or other castings or forgings; but a pillar, standard
or wall plate may be substituted for the anchoring electro magnet when the
machines are used in workshops.
It will be understood that these arrangements may be modified such as com-
bining automatic reversing of the travelling emery wheel with other arrange-
ments of motor or with belt gear from any adjacent prime moving shaft.
In some cases the machines may be driven entirely by belts without the use of
motors.
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;-
First. In emery wheel machines for polishing metal surfaces the combination
comprising an emery wheel mounted on an adjustable transverse spindle, a longi-
tudinal traversing frame carrying the aforesaid, and an anchoring electro magnet
or its equivalent with counterbalance levers or weights, substantially as set forth.
Second. In emery wheel machines for polishing metal surfaces, the combina-
tion comprising a traversing framing an electro motor carried by said framing,
and gearing and clutch connections so as to automatically control the longitudinal
traversing movements of framing and emery wheel, substantially as set forth.
