Improvements in Lubricators.
I, HENRY NIELD BICKERTON Engineer Park Street Iron Works Ashtonunderlyne,
do hereby declare the nature of this invention to be as follows:-
:-
The object of this Invention, is to construct a lubricator, or vessel containing
lubricant in such a manner that the delivery of the lubricant, shall be regulated and
controlled, by a clockwork attachment, thus insuring the certain delivery of the
required quantity of the lubricant in a given time.
According to one arrangement, I employ a cylender of convenient size, in which is
fitted an oil tight piston, such piston being forced in one direction, by a spring or
may be allowed to fall by its own weight. To this piston I attach a chain, the said
chain being wound round a drum, similar to that of an ordinary clock. The winding
on of this chain is performed by hand thus tightening up the spring, and drawing
the piston to one end of the cylender.
At the opposite end I form a small outlet to which a nipple or pipe may be
attached to convey the oil or lubricant to the desired place. It will thus be seen that
if the unwinding of the chain, and consequent motion of the piston, is under the
control of a star wheel, and escapement lever, such lever being controlled by a
pendulum, or coil spring, in the ordinary and well known manner, it will entirely
depend upon the speed of the latter, what quantity of Lubricant is forced through
the small outlet, and this speed having once been set, will be certain and
continuous.
In cases where it is desirous to feed the lubricant under pressure, as in Engine,
and pump cylenders, valves &c. I allow such pressure free access, to the spring.side
of the piston, so as to bring the lubricant in equalabrium, or make the spring of
sufficient strength, to force the lubricant in against the pressure.
According to another arrangement, 1 force the piston by a rack and wheel, or by
a worm and nut, in either case the wheel and nut, are actuated by the clock attach-
ment, the clock in these cases being worked by an ordinary clock spring, or I form
the outlet from the vessel, so that it may be moved gradually lower by the clock
attachment, thus allowing the oil or lubricant to escape by its own gravity.
In cases where the lubricator is fed under pressure, in order that the rate of feed
may be visible to the eye, I arrange the lubricant to drop from a nipple in a small
box, one or both sides of which are formed of glass.
