Improvements in Polishing Machinery.
GEORGE FREDERIck Chutter, Engineer, 46, Constitution Hill, Birmingham,
do hereby declare the nature of this invention to be as follows:-
A combination of two or more spindles, carrying mops or bobs" running in
diagonally divided bearings, mounted on slides, with adjacent steadies or holders
over dust trays or hoppers, containing grids and discharging into base of machine.
This combination is principally for polishing tubes and rods of circular or polygon
section on a base of cast iron there is fixed a bed, on this bed there are two
saddles, moved together or apart by a screw cut right hand at one end and left
hand at the other. Each saddle has bearings on its top side to carry spindles.
The spindles are parallel to one another and at right angles to bed. The ends
of spindles carry mops or bobs for the polishing process. On opposite sides of
bed, steadies are fixed to carry the tubes or rods to be polished. The steadies and
tubes are between the spindles on the same plane. The spindles have pulleys
and are driven in opposite directions, that is towards one another.
The mops
being fixed to spindles also revolve. The tube to be polished is passed through
the steadies and between the revolving mops and is thereby polished at the ratio of
250 feet per hour.

I, GEORGE FREDERICK CHUTTER, Engineer, 46, Constitution Hill, Birmingham,
in the County of Warwick, 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:-
My invention has for its object improvements in polishing machinery by which
I enable the mops or bobs to be used until all worn away while at the same time
their application and adjustment with regard to the work is considerably facili-
tated and the dust is conveniently collected for re-use.
In order that my invention may be clearly understood and more easily carried
into practise, I have appended hereunto three sheets of drawings upon which I have
fully illustrated the nature of my said improvement.
Figure 1 is a general view of one of my polishing machines.

page_text: Figure 3 is a cross sectional elevation of bearings shewing part in section.
Figure 4 is a longitudinal elevation of bearing shewing bed in section.
In carrying my invention into effect I provide two or more spindles A A¹
carrying mops or bobs B B and running in the bearings C C¹ which are diagonally
divided or inclined as shewn to allow of the two spindles A A being brought
as closely together as possible by which means the mops or bobs B B can be
worn to a much greater extent than hithertofore. The diagonally divided bearings
are mounted on the saddles D D¹ which slide on the bed E and are controlled by
the right and left handed screw F which passes through the bed and which is
provided with nuts H H having the studs 2 for engaging with the bearing
slides ) D and a handle K is provided for moving the said saddles and bearings
as required. The bed E is supported by the base L the dust trays or hoppers M
being attached thereto in a convenient position for catching the dust as it falls
from the work and conveying into the said base from whence it can be readily
removed through the door N. The tube or rod to be worked is passed through the
steadies or guides P and suitable pullies R and R¹ are provided upon the
spindles A and A¹ which are driven in opposite directions. The action of polishing
being as follows. The tube or rod of circular or polygon section to be polished
being passed through the steadies P the revolving mops B and B are brought to
bear on the work by means of the handle K through the left and right hand
screw F and is thereby polished at the rate of about 250 feet per hour while the
dust drops into the hopper M as before described.
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 :-
1st. In an improved polishing machine the diagonally divided bearings C C¹
operated by a right and left handed screw, substantially as and for the purpose
herein set forth and illustrated.
2nd. In combination with Claim 1 the hopper M substantially as and for the
purpose herein set forth and illustrated.
