PROVISIONAL SPECIFICATION.
Improved Lubricator.
1. DUNCAN FAULDS Engineer 6 Athol Street Barrow-in-Furness do hereby
declare the nature of this invention to be as follows
This lubricator is formed for the use of solidified oils or any other oil of a semi
solid character that requires forcing to the bearing. This lubricator is also fitted
with cup leather piston which becomes perfectly tight with the pressure and
prevents lubricant from passing behind piston. This lubricator is also fitted with
regulating screw hollowed out to fit spiral spring which forms a guide for
piston and a constant pressure on lubricant throughout length of cylinder.
The small nut screwed on piston rod holds up spring & piston when refilling cup.
When cap is screwed on the nut to be taken off to allow spring to expand. By
this appliance the lubricant is gradually forced out and a continous supply fed to
the bearing. Thus securing a more perfect and economical lubrication. This
lubricator is so arranged that it can be placed at any angle.

Improved Lubricator.
I, DUNCAN FAULDS Engineer 6 Athol Street Barrow-in-Furness 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 :-
This lubricator is formed for the use of solidified oil or any other oil of a semi
solid character that requires forcing to the bearing. This lubricator is also fitted
with cup leather piston which becomes perfectly tight with the pressure and
prevents lubricant from passing behind piston. This lubricator is also fitted with
regulating screw hollowed to fit spiral spring which forms a guide for piston and a
constant pressure on lubricant throughout length of cylinder. This lubricator can
also be fitted with worm movement on top of regulating screw. By this appliance
the lubricant is gradually forced out and a continuos supply fed to the bearing.
Thus securing a more perfect and economical lubrication. This lubricator is so
arranged that it can be placed at any angle.
Letter A denotes cylinder cover. Cworm and shaft which works into corre-
sponding toothed wheel B, which is screwed internally to fit regulating screw D,
which is hollowed to fit spiral spring F, which when compressed by rachet motion H,
forms a pressure on piston G, and causes lubricant to be forced out. Piston rod E
square on end to fit regulating screw D which prevents the said screw from
turning round with worm wheel B, which fits loose in cylinder cap A, with screwed
washer on bottom to prevent wheel B from rising with pressure of spiral spring by
this appliance on all oscillating movements it feeds automatically, such as pump
levers crank pins &c. &c. and for any ordinary bearing can be worked without worm
motion when spring can be compressed by hand.
