PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Lubricating the
Piston and Valve Rods of Engines.
We, JOHN ROBERT HOWDEN Engineer, and HENRY JOHNSON, Joiner, both
of City Mills Morley, near Leeds, in the County of York, do hereby declare the
nature of this invention to be as follows:-
The object of our invention is to lubricate the piston rod at both ends' if required,
also the valve spindles of engines at the same time.
We attach to the feed tube of an ordinary sight feed lubricator a tube or tubes
passing to the glands of the piston rods and to the valve spindles, such tube
being provided with regulating valves; by this means there is a great saving in
the packing and the friction is decreased by the more perfect lubrication attained.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Lubricating the
Piston and Valve Rods of Engines.
We, JOHN ROBERT HOWDEN, Engineer, and HENRY JOHNSON, Joiner, both
of City Mills, Morley, near Leeds, in the County of York, do hereby declare the
nature of this invention, and in what manner the same is to he performed, to be
particularly described and ascertained in and by the following statement :-
Hitherto piston rods, valve spindles, and the like, have been very imperfectly
lubricated, and the packing, by continued working of such rods or spindles, has
become extremely hard, causing thereby "grooving" of the rods or spindles, at
the same time allowing a considerable escape of steam to take place at the glands.
The object of our invention is to provide apparatus whereby piston rods, valve
spindles, and the like, can be lubricated in a more efficient manner than heretofore,
and by the employment of such apparatus the engine will be found to work more
smoothly, whilst power will be gained by reducing the friction, at the same time
preventing the escape of steam or "blowing" at the glands.
In order that our invention may be clearly understood, we will proceed to
describe same with reference to the accompanying drawings, in which similar
letters refer to like parts in both figures.
Fig. 1 is a side elevation, and Fig. 2 a plan, shewing part of an engine with our
improvements applied thereto.
According to our invention, we employ the ordinary sight feed lubricator A,
which is so connected with the cylinder B as to feed or supply oil to such cylinder
at a pressure equal to that of the steam.
Into the gland E of the cylinder B, and glands F of the valve spindles G, we
screw or otherwise mount suitable oil cups H which are provided with regulating
valves H', and by means of the tubes or pipes K connect such oil cups H to the
feed tube or oil chamber A' of the sight feed lubricator A; or the tubes or
pipes K may pass direct into the glands E and F. By thus connecting the
glands E and F with the sight feed lubricator A, oil will be fed to such glands at
a pressure equal to that of the steam, and by means of the regulating valves H¹

page_text: the supply of oil to such packing may be readily increased or diminished as may
be required.
By employing the above described arrangement, the packing in the glands is
kept saturated with oil, thus effecting a great saving in the cost of packing, whilst
the friction is considerably reduced by the more perfect lubrication attained.
Although we have shewn in the drawings only one class of engine with our
improvements applied thereto, it will be readily understood that the arrangement
of tubes or pipes K for connecting the glands with the sight feed lubricator may be
varied to suit the various olasses or types of engines to which such improvements
are applied.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
olaim is:
1. The combination of the sight feed lubricator A, the tubes or pipes K, and the
regulating valves H', substantially as, and for the purposes set forth.
2. The general arrangement, construction, and combination of the various parts
forming the means or apparatus for lubricating piston rods, valve spindles, and the
like, substantially as herein set forth.
