EDWARD REILLY 108 Newmarket Street Grimsby Marine Engineer. I do
hereby declare the nature of this invention to be as follows:-
A reservoir round a piston rod immediately under the glan, next comes a turn of
flax packing held up by a thin flange with recess. The flange is kept in its position
by the glan studs. The supply of oil is taken from a cup fastened on side of
cylinder Drop is regulated with spring valve, manipulated by thumbscrew.

Improvements in Piston Rod Lubricators for Marine and other
Engines.
I, EDWARD REILLY, of 108, Newmarket Street, Grimsby, in the County of
Lincoln, Marine 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 :-
This invention relates more particularly to those lubricators which are used for
lubricating piston rods and the like surfaces of marine and other engines by means
of packing soaked with the lubricant.
According to this invention the improved lubricator consists of a reservoir
extending in the form of an annular chamber round the piston rod immediately
under the gland. Next comes a turn of flax or equivalent packing material held
up in surface contact with the piston rod by a thin flange suitably recessed and
kept in its position by the gland studs and nuts. The supply of oil is conveyed
into the reservoir and is taken from a cup fastened on the side of the cylinder or
other convenient position; the drop being regulated with a spring valve manipulated
by a thumb screw; or the oil may be supplied to reservoir by other means, it
being only essential that the supply should be uniform, continuous and with means
for regulating the amount supplied.
The object and result of my invention is to provide an easy and efficient means
of lubrication in which the structural compactness of the lubricator adapts it for
use in existing engines and in which the packing chamber can be closed up to the
packing to prevent access of dust, dirt, grit or the like foreign matter, and to cause
the packing to bear equally round the surface of the piston rod, and furthermore a
more equal distribution of the lubricant to the packing is attained by conveying the
supply through an annular chamber.
Having described the nature of my improved lubricator and its utility I will now
proceed further to explain the same, and the manuer by which my said invention
is to be carried into practice by referring to the drawing hereto aunexed.

page_text: Fig. 1 is a sectional elevation of the lubricator and of the adjoining parts to
which it is connected, all arranged and fitted together in the working position as
applied to a piston rod with a four studded gland.
Fig. 2 is a corresponding plan view of Fig. 1.
Figs. 3 and 4 are precisely similar views to Figs. 1 and 2 respectively except
that the packing chamber is slightly varied in form and the general arrangement
is adapted to a two studded gland. The oil cap and its accessories are omitted in
all the figures.
a is the piston rod, the stuffing box and c the gland under which the oil
reservoir d is provided in the form of an annular chamber. When the lubricator
is to be used for lubricating the piston rods of existing engines, this reservoir
is made up of two parts or halves which can be fitted together as required without
disturbing any of the engine fittings, otherwise the said reservoir is made in one
piece. In the former case the two parts of the reservoir are fastened together by
any suitable means such as by a small cover plate e secured as shown over each
joint, is the packing of flax or other suitable or equivalent material. This
packing and reservoir d are held in position by the auxiliary gland g secured by
check nuts to the gland studs h. In the case of existing engines this gland
is made in two pieces united together, but otherwise in one piece. This gland g
and the underside of the reservoir d form between them a chamber for the packing
material which chamber is adjustable to close up against the packing with any
required degree of pressure, which construction excludes dirt, grit or other foreign
matter from getting access to the packing, and tends to cause the packing to bear
equally round the surface of the rod. This chamber can be also varied in form and
capacity according to the formation of the underside of the reservoir d and the lip
of the gland g as may be observed by comparing Figs. 1 and 3 in this respect.
The action of the lubricator is as follows:-The ordinary oil box (not shown) is
connected with the reservoir d by a pipe k, the supply of oil being regulated by a
valve in the said box. The oil flows through the pipe k into the reservoir d, thence
through the annular space round to the packing which bears against the piston
rod a forming a soft and permanent swab, which keeps the said rod thoroughly and
economically lubricated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The particular arrangement and combination of parts constituting a lubricator in
which the packing material is enclosed in an adjustable chamber to which oil
is supplied through an annular reservoir, substantially as and for the purpose as
hereinbefore described with reference to the accompanying drawing.
