follows:-
To consist of a metal cylinder fitted with a coarse pitch spiral worm, and caused
to revolve inside thereof and force grease down a tube fixed to bottom of the said
cylinder leading to shafts running in bearings.
The said spiral worm being actuated either by hand, or automatically by
mechanical appliances according to the nature and arrangement of the bearings
and shafts operated upon.
The grease will be composed of vegetable oils (such as castor, olive, or cocoa-nut
oils) and alkali soap or other neutralizer in equal parts, with an addition of one-
fourth part of arrowroot starch and distilled water combined.

page_text: Improvements in Lubricating the Bearings of Shafts.
HENRY BROUGH, of 21, Hope Terrace, Lilyput Road, Victoria Docks, London,
Marine Engineer, do hereby declare the nature of this invention and in what
manuer the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The invention relates to a new or improved method of applying an inspissate
uninflammable grease, with economy and ease, to the bearings of rotary shafts and
axles of every description.
In carrying my invention into effect I employ a helical curved disc, technically
known and hereinafter referred to, as a spiral worm, to revolve in a cylinder, directly
above cross ribs, cut out at the points of intersection and fixed to a base plate
forming the bottom of the cylinder, to which is also attached a tube for conducting
the lubricant through the metal or material forming the shaft bearing, above the
aforesaid cross ribs and secured thereto I employ a small tube for the purposes of
providing an axis for the said spiral worm to revolve upon, and provide a passage
for the cleaning rod, which consists of a copper (or other rapid heat-conducting
metal) rod with an elongated screw for the purpose of clearing the conducting tube
periodically, and by withdrawing the said rod, the temperature of the bearing at
the seat of friction can be effectually ascertained.
Within the said cylinder I place an inspissate uninflammable grease, (and
hereinafter referred to as grease) composed of vegetable oils (such as castor, olive,
or cocoanut oil), and alkali soap or other neutralizer in equal parts or otherwise,
with an addition of 25 per cent. more or less of arrowroot or flour of any cellular
grain.
The spiral worm which is free to revolve in the cover attached to the aforesaid
cylinder is placed amongst the grease and caused to revolve by manual or mechanical
power as may be desired.
The bottom face or cheek of the spiral worm as it revolves, forces the grease out
of the spaces between the said cross ribs through the openings caused by cutting
out the points of intersections of same, down the tube to the shaft or axle operated
upon, the spaces between the said cross ribs being refilled from the top or inner
face of the spiral worm.
And in order that my said invention may be clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully
to describe the same.

page_text: cover (D) by a hand-wheel (E), for manipulating the spiral worm (A) and giving
it the necessary rotative movement periodically or as often as the bearing operated
upon may require, and for an automatic motion a screw or ratchet-wheel is
substituted in place of the hand-wheel (E) actuated by a stud or collar upon the
shaft, or otherwise according to the arrangement of the shaft or axle bearing.
The spiral worm (A) is free to revolve within a cylinder (F), directly above and
close to four or more cross ribs (H), forming part of the base plate (I), the cover (D)
being secured to the cylinder (F) by pins (K), or otherwise, the points of inter-
section of the cross ribs (H), being cut to form passages (L), direct into the tube (M),
fixed to the base plate (I), for conducting the aforesaid-mentioned grease through
the metal or material forming the bearing of a shaft or axle.
In order to ascertain with facility the temperature of the bearing operated upon
at the seat of friction, I fix to the top of cross ribs (H), a small tube (N), which
passing through the hollow spindle (B), forms an axis for the same to rotate upon,
and a direct way for the cleaning rod (0), constructed of copper (or other rapid
heat-conducting metal) in the form of an elongated screw, for the purpose of
clearing the tube (M) periodically, and by withdrawing the said rod (O) occasionally,
the temperature of the bearing at the seat of friction can be ascertained.
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. Arranging a helical curved disc, technically known as a spiral worm, in
conjunction with cross ribs, to force an inspissate grease to the seat of friction in
shaft or axle bearings.
Second. The compounding of an inspissate uninflammable grease that will not
ruin from the bearings operated upon.
Third. Arranging the cleaning rod forming part of my invention to ascertain the
temperature of the bearings operated upon.
