PROVISIONAL SPECIFICATION.
Improvements in Lubricating Apparatus.
FRANK TRIER ERNEST TRIER Engineers of 19 Great George Street
Westminster London do hereby declare the nature of this invention to be as
follows:-
Our improvements relate to appliances by means of which semisolid lubricants
can be forced from a stationary lubricator to rotating parts of machinery, such as
crank pins etc., whilst they are in motion.
In carrying out our invention we employ a ring with flexible lips or other
suitable sensitive packing. These lips (of leather or other suitable material) bear
lightly against circular seatings of a second ring, which with the first forms an
enclosed annular groove or space. One of the rings is concentrically fixed to the
rotating part of the machinery (for instance to a crank) or it can be formed as an
integral part of the latter & it has an outlet communicating with the part to be
lubricated (for instance a crankpin). The other ring is stationary & concentric
with the first & communicates with a lubricator with which semisolid lubricant is
forced into the annular space formed by the two rings & from thence to the
bearing.
Whilst under pressure the flexible lips or sensitive packings press sufficiently
tight against their seatings to prevent the escape of the lubricant but not to
prevent the free rotation of the revolving ring or seating. Where a shaft does not
pass thro' the ring or rings a disc or discs may be substituted & one of the lips
dispensed with.

Improvements in Lubricating Apparatus.
FRANK TRIER and ERNEST TRIER Engineers of 19 Great George Street
Westminster London 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 :-
Our improvements relate to appliances by means of which semi-solid lubricants
can be forced from a stationary lubricator to rotating parts of machinery such as
crank pins etc., whilst they are in motion.
Figs. 1 & 2 of the accompanying drawings show an appliance in section & front
view fixed to a crank C & which consists principally of two rings A & B. The
ring B is provided with flexible lips R R of leather or other suitable material,
which bear lightly against or run just clear of circular seatings of the second
ring A & which with the first forms an enclosed annular groove or space. The
ring A is concentrically fixed by the clamping ring D & the screws S S S to the
crankshaft, but it could also be formed as an integral part of the latter & the hole O
is provided communicating with the crank bearing.
The ring B is stationary & communicates with a lubricator L (a Stauffer
lubricator is shown) with which the semisolid lubricant can be forced into the
annular space formed by the two rings & from thence to the bearing.

page_text: Whilst under pressure the flexible lips or sensitive packings press sufficiently
tight against their seatings to prevent the escape of the lubricant but not to
prevent free rotation. In Fig. 3, a somewhat different arrangement is shown, the
ring A being within the ring B. The ring provided with the lips or packing
may also be fixed to the rotating part of machinery & the ringseating may be
stationary. Where a shaft does not pass thro' the ring or rings, a disc or discs may
be substituted & one of the lips dispensed with.
Having now described and ascertained the nature of our said invention
& in what manner the same is to be performed, we declare that what we
claim is :
A lubricating apparatus for semisolid lubricants consisting principally of two
rings one of which is fixed to the moveable part of machinery & the other
communicates with a pressure lubricator, the greasetight joint being formed by the
flexible lips substantially as described.
