PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Lubricating Moving Parts of
Machinery.
We, CHARLES HIBBERT BERRY, Engineer, of 34 George Street, Moss Lane
East, Manchester, and JOHN SNOWDON Junior of Lowe's Wharf, Millwall, in the
County of London, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
In the Specification No. 10348 of 1885 is described apparatus whereby solid
lubricant, such for instance as asbestoline, is forced by a piston moved slowly along
a cylinder containing the lubricant, so as to be conveyed by pipes or other conduits
to bearings and other parts of machinery requiring lubrication.
The present invention relates to appliances to be used in connection with
apparatus of the kind referred to, for the purpose of conveying the lubricant to
revolving parts such as crank pins or eyes of connecting rods or to sliding parts
such as crossheads or slippers.
In order to lubricate a projecting crank pin, we place forcing apparatus of the
kind described in the Specification above referred to, in such a position that a lateral
aperture by which the lubricant is forced out is in line with the axis of the crank
shaft, and from this aperture we connect a pipe in the form of a crank to a hole
bored in the centre of the crank pin leading by a cross hole to the periphery of the
pin. As the crank pin revolves the crank lubricating pipe revolves with it, and an
eccentric or cam upon it works the pawl lever which actuates the worm gear by
which the pressing piston is moved. When it is desired to connect the lubricating
pipe to the side of the eye of a connecting rod or to the strap of an eccentric or to
a slipper or crosshead, we joint the pipe so as to form lazy tougs which are folded
together or drawn out as the connecting rod moves in its circular path or as the
slipper or crosshead reciprocates. In this case a limb of the lazy tongs next the
pressing cylinder may move the pawl.
Instead of making the lubricating pipe in the form of a lazy tongs, it may be a
flexible metallic pipe wound round a spring drum through the tubular axis of
which the lubricant is forced into the pipe. In many cases where the movement is
not very great the lubricating pipe may be made with a bend or with several bends
or flexible parts which yield sufficiently to allow for the motion of the part to
which the pipe is connected.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Lubricating Moving Parts of
Machinery.
We, CHARLES HIBBERT BERRY, Engineer, of 34 George Street, Moss Lane
East, Manchester, and Joux SNOWDON Junior of Lowe's Wharf, Millwall, in the
County of London, Manufacturer, 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 :-
In the Specification No. 10348 of 1885 is described apparatus whereby solid
[ Prins 8.77

page_text: lubricant, such for instance as asbestoline, is forced by a piston moved slowly along
a cylinder containing the lubricant, so as to he conveyed by pipes or other conduits
to hearings and other parts of machinery requiring lubrication.
The present invention relates to appliances to be used in connection with
apparatus of the kind referred to, for the purpose of conveying the lubricant to
revolving parts such as crank pins or eyes of connecting rods or to sliding parts
such as crossheads or slippers, as we shall describe referring to the accompanying
drawinga.
In order to lubricate a projecting crank pin as shewn in Fig. 1, we place forcing
apparatus of the kind described in the Specification above referred to and shewn
in side view in Fig. 2, in such a position that the lateral aperture A by which the
lubricant is forced out is in line with the axis of the crank shaft S, and from the
aperture A we connect through a stuffing box a pipe P in the form of a crank to a
hole bored in the centre of the crank pin C leading by a cross hole to the periphery
of the pin.
As the crank pin revolves the crank lubricating pipe P revolves with it, and an
excentric or cam E upon it works the pawl lever which actuates the worm gear by
which the pressing piston is moved. The pipe P may be connected to the crank
pin C by a tubular link pas shewn in Fig. 3. The pipe P may be made to slide
telescopically as shewn in Fig. 4 to allow for the centres of A and S being out of
line. For the same reason the modification shewn in Fig. 5 may be used, the
pipe P being fitted to slide in a block Q attached to the crank pin C, the lubricant
passing through a slot cut through the side of the pipe P. When it is desired to
connect the lubricating pipe to the side of the eye of a connecting rod R or to the
strap of an excentric or to a slipper or crosshead we joint the pipe as shewn in
Fig. 6 so as to form lazy tongs L which are folded together or drawn out as
the connecting rod moves in its circular path or as the slipper or crosshead
reciprocates. In this case a limb M of the lazy tongs next the aperture A of
the pressing cylinder may move the pawl of the forcing apparatus F.
Instead of making the lubricating pipe in the form of a lazy tongs as shewn
in Fig. 6 it may be as shewn in Fig. 7 a flexible metallic pipe P wound round a
spring drum D through the tubular axis of which the lubricant is forced into
the pipe P. In many cases where the movement is not very great the lubricating
pipe may be made with a bend or with several bends or flexible parts which
yield sufficiently to allow for the motion of the part to which the pipe is
connected.
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. For lubricating a crank pin, a pipe of crank form arranged to revolve with
the crank around the aperture whence lubricant is supplied and connected to
the crank pin, substantially as described.
2. Arranging the crank pipe above referred to so that it can slide longitudinally,
substantially as and for the purpose set forth.
3. Connecting the aperture for supply of lubricant to the eye of a connecting
rod or other moving part through pipes jointed to form lazy tongs, substantially
as described.
4. Connecting the aperture for supply of lubricant to the eye of a connecting
rod or other moving art through a spring drum and a flexible pipe alternately
wound on and wound off the drum, substantially as described.
