I, RICHARD Cox of Park Foundry Weymouth in the County of Dorset, Engineer,
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:
This machine is designed to supply a revolving horizontal disc to be driven by power
which shall rapidly and effectively level or smooth or polish the surface of substances
placed directly below it.
It consists of two horizontal bars one above the other, connected at their ends to
a vertical frame, or instead of the bars a planed bed with V shaped edges may be
employed.
Attached to these bars is a saddle which slides to and fro thereon and is caused to
travel to and fro by a revolving screw, worked by an alternating motion communicated
by pulleys and straps in the usual manner. This saddle carries the vertical spindle of
the polishing disc.
From the saddle two arms project upwards which connect to a short tube or sleeve
around a square or grooved revolving shaft.
Fitted on this revolving shaft is a mitred wheel which revolves with the shaft, but
slides to and fro with the saddle, and communicates motion to a pinion on the summit
of the vertical spindle of the polishing disc.
On the vertical spindle before named is a hand-wheel to regulate the pressure on
the work. There is also a lock wheel to fix the same. The hand-wheel is attached to
a small tube which has an exterior thread, and screws into a nut in one of the guide
arms. A collar is fixed on the vertical spindle at each end of the tube, so that by
turning the hand-wheel, pressure is applied to, or removed from, the spindle and disc
to the extent required.
The surface of the disc is formed of suitable metal or covered with the necessary
abrading or polishing materials..
Below is a table on which the work is placed. This table is mounted on rollers and
is propelled to and fro laterally at right angles to the line of motion of the disc, so that

page_text: the whole of the work may be brought under the disc. A ra
handle are provided to propel the table.

H is the vertical spindle.
I is the rotating disc.
K is a hand-wheel through which the spindle H runs.
L is a lock wheel.
M is a table or platform.
N is a rack for shifting table.
O is a handle for operating N.
P. P. are the pulleys.
R. R. are the rollers under the table.
S. is the tube with exterior thread attached to K.

V. V. are collars on the spindle H.
Having now particularly described and ascertained the
Invention, and in what manner the same is to be performed,
I claim is:
(1) A machine for rubbing or polishing glass, marble ston
consisting of a table working to & fro on rollers, above which is a
disc with vertical spindle rotated by mitred wheels from a horizo
other convenient way the said disc and spindle being mounte
travels to and fro on horizontal bars or otherwise, as herein descr
(2) In a machine for rubbing or polishing horizontal surface
the frame A. the Bars B. B, the saddle C, the screw D, the shaft E, th
the vertical spindle H, the disc I, the wheels K L. with the table ra
as berein explained and set forth.
