Improvements in the Manufacture of Hubs for Wheels, Roller and
other Bearings or Wearing Surfaces and like Uses.
1, GEORGE BESTWICK, of 192, Green Lane, Patricroft, in the County of Lan-
caster, Engineer, do hereby declare the nature of this invention to be as follows:-
The improvement which forms the subject of this invention relates to the
substitution for brass, iron, or steel of a combination of the hard substance or
interior portion of Corozo pippin with graphite for the manufacture or production
of such articles or uses as the cones in the hubs of wheels, roller and other bear-
ings or wearing surfaces in cotton spinning machinery, footsteps, and similar
articles of a hard and inflexible nature, such as pickers for looms
For the purpose of this invention I employ the interior hard substance of
Corozo pippin which is obtained after the rind and fruit has been taken therefrom.
1 steep said substance in a solution of chloride of lime for several hours and then
turn in a lathe or otherwise produce therefrom the article required such as herein-
before named. I face the wearing parts with graphite by forming holes or per-
forations in the Corozo and applying thereto the graphite in the form of a thick
paste which is pressed on and firmly united thereto by hydraulic pressure, when
it may be finished by emery.

I, GEORGE BESTWICK, of 192, Green Lane, Patricroft, in the County of Lan-
caster, 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:-
The improvement which forms the subject of this invention relates to the sub-
stitution for brass, iron, or steel of a combination of the hard substance or in-
terior portion of the Corozo pippin with graphite for the manufacture or pro-
ductions of such articles or uses as the cones in the hubs of wheels, roller and
other bearings or wearing surfaces in cotton spinning machinery, footsteps, and
similar articles of a hard and unflexible nature, such as pickers for looms
For the purpose of this invention I employ the nut or interior hard substance
of the Corozo pippin which is obtained after the rind and fruit has been taken

page_text: therefrom I steep said substance in a solution of chloride of lime for several hours
in order to destroy the acid therein and when dried turn in a lathe or otherwise
produce therefrom the article required such as herein before named. I face the
wearing parts of the articles with graphite by forming holes or perforations
therein and applying to said wearing surfaces the graphite in the form of a thick
paste which is pressed on or in and firmly united thereto by hydraulic pressure,
when it may be finished by emery.
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:
-
The manufacture or production from the Corozo nut of hard or inflexible
articles or uses such as the cones in the hubs of wheels, roller and other bearings
in cotton spinning machinery footsteps and the like and facing the wearing sur-
faces of said articles or uses with graphite by means of holes or perforations
formed in the article into which the graphite in the form of a paste is pressed
substantially as and for the purpose hereinbefore described.
