I, WILLIAM HARDY KENT, of Kirby Street, Hatton Garden, in the
5 County of Middlesex, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES FOR CLEANING
AND POLISHING KNIVES AND OTHER METAL ARTICLES," to be as follows:-
This Invention relates to improvements in the arrangement and con-
struction of machines for cleaning and polishing knives and other metal

page_text: articles. For this purpose the cylinders, cones, or discs employed for
cleaning and polishing the knives or other articles are mounted in a
frame, being fixed or stationary, in place of revolving, as heretofore, the
knives or other articles being arranged in rims or holders which revolve
in place of being stationary, as heretofore.
The space or division in which the blades of the knives or other
articles revolve is lined with any suitable polishing materials, such as
leather, cork, india-rubber, or any other suitable material for cleaning
and polishing metal.
The polishing material can be placed flat on the polishing surfaces 1
with or without elastic packing beneath, or leather or other suitable
material can be arranged edgeways with or without clastic supports,
such as steel springs, cork, wire springs, or other suitable material or
appliance.
