Improvements in Lubricating Apparatus.
We, CHARLES HIBBERT BERRY, Engineer, of 16 Haslinglou Street, Moss
Side, Manchester, in the County of Lancaster, and JOHN SNOWDON Junior, of
Westferry Road, Millwall, in the County of London, Manufacturer, do hereby
declare the nature of this invention and in what manner the saine is to be
performed to be particularly described and ascertained in and by the following
statement :-
This invention relates to the construction of a lubricator specially suited for
supplying lubricant of a greasy nature, either to stationary or to moving parts of
engines and machinery, as we shall describe referring to the accompanying
drawings.
Fig. 1 is a longitudinal section shewing a lubricator according to this invention
applied to the lubrication of a crank pin.
Fig. 2 is a front view with part of the cover broken away to shew the
interior.
Fig. 3 is a section partly in elevation, to a reduced scale, showing the jointing
employed when the lubricator is applied to an oscillating part such as the eye of
a connecting rod.
A is a cylinder which is screwed on a seating B and is fitted with a piston C
on which bear several springs D. A hand wheel and screw E having on it a
collar F may be used to aid the springs in pressing the piston so as to squeeze the
lubricant out by the pipe G. For the purpose of charging the cylinder, it is
unscrewed from the seating and the piston is withdrawn by unscrewing the screw E,
its collar then bearing against the bracket H which projects from the piston.
A tube or it might be a rod I projects through a hole of the cover acting as an
indicator shewing the position of the piston and the quantity of lubricant in the
cylinder. This tube also serves (the outer cap being removed) to adinit air into
the cylinder when the piston is being drawn back, and thus prevent the lubricant
being drawn out of the connecting tubes Gaud L.
When the lubricator is employed for a stationary bearing or rubbing surface the
lubricant is led by the pipe G to the required point.
When a revolving crank pin is to be lubricated as shewn, the lubricator is placed
in the axial line of the crankshaft and is connected through a packed union K and
pipo L to the passage for lubricant in the crank pin M.
For double webbed cranks the arrangement would be suitably modified. Thus
for example in the arrangement shown at Fig. 4 where Q is the framing of an
engine and R the connecting rod leading down to the crank, the lubricator A is
carried by the framing and is connected by pipes L L' L' having swivel unions.
at to a pipe leading down along the connecting rod to the head of the
latter which is connected to the double webbed crank of the ongiue, the lubricant
being in this case supplied to the crank pin through a passage in the connecting
rod head.
The lubricator usually revolves with the crank shaft, but the union K allows.
of its remaining stationary while the shaft revolves so that the screw E can be
turned by hand, and also the lubricator can be unscrewed to be charged. When
an oscillating part such as the eye of a connecting rod has to be lubricated, the
pipe G is connected to the passage for lubricant in the eye through two unions N.
and O both provided with packed stuffing boxes.

page_text: In order to provide more effectually against leakage of lubricant from the unions,
the one member of each union is screwed at P into the other member, and partially
screws and unscrews itself at each oscillation.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A. lubricator constructed and operating substantially as described with
reference to the accompanying drawings.
2. In combination with the lubricator above referred to a union K and pipe L
for lubricating a crank pin, substantially as and for the purpose set forth.
3. In combination with a lubricator for lubricating an oscillating part a pair of
unions N and O, substantially as described.
