Improvements in or connected with Apparatus for Packing and
Lubricating Piston and other Rods.
1, ROBERT ARCHER, of Ossett, near Leeds, in the County of York, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide apparatus whereby piston and other rods
may be efficiently lubricated.
According to my invention I employ a casing or circular box, having inner and
outer parts which are screwed or otherwise fastened together and through the centre
of which the piston rod of the engine passes. At one of the ends of the box, a
disc is provided, being kept from contact with the said box. end by a spring or
springs which may suitably be held in position by projections or recesses in the
box end. These springs may pass through apertures in the box end and
rest against the piston gland or other suitable surface, or the box may be
held in position by suitable springs situated between the gland and the said box.
On the disc and around the piston rod I place three or other suitable number of
wearing pieces forming a circular set, and on these wearing pieces I place another
similar set, in such a manner that the joints of one set, are covered by the pieces
of the other set, their relative positions being maintained by suitable pins and
recesses. Two, three, or more of these sets may be employed, according to require-
ments. At the outside of these wearing pieces I provide three or other suitable
number of compressing segments, which are of or about the depth of the combined
sets of wearing pieces; and at the outside of these compressing segments, recesses
or apertures are formed for the reception of springs, which press against the said
segments from the interior of the box, and thus press the wearing pieces toward the
piston rod.
A pin or other suitable connection keeps the wearing pieces in their
positions with relation to the compression segments.
On screwing the outer part of the casing into position, the various parts are
pressed between its inner face and the springs at the other end of the case, thus
holding the said parts in a resilient manner in their required positions.
To the stuffing box I attach a tube having a lubricator connected with its upper
end, the base of this lubricator being in connection with a tube of small diameter
which passes down the centre of the first tube. In the lubricating packing above
described I connect another tube, which enters loosely between the two tubes in the
stuffing box. This arrangement allows of a free entrance of oil to all parts of the
metallic packing whilst the said packing is not impeded from free movement.
Instead of the above tubes à stuffing box may be employed for connecting the oil
lubricator to the packing.
In this manner I obtain a packing which is of a springy and yielding nature, and
which is free to vibrate or move with the vibrations or movements of the piston rod,
whilst at the same time the lubricant is conveyed to the piston rod in a free and
efficient manner, thereby enabling the engine to work with much greater case and
efficiency than heretofore.
Dated this 25th day of January 1895.

Improvements in or connected with Apparatus for Packing and
Lubricating Piston and other Rods.
I, ROBERT ARCHER, of Ossett, near Leeds, in the County of York, 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:
The object of my invention is to provide apparatus whereby piston and other
rods may be more efficiently lubricated than heretofore.
In order that my invention may be clearly understood I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Figs. 1 and 2 are respectively transverse and longitudinal sections of a lubricating
packing, and Fig. 3 is a longitudinal section of a stuffing box, shewing arrangement
of apparatus for supplying the packing with lubricant, all constructed according
to my invention.
In carrying my invention into effect 1 employ a casing or circular box A, and
in the interior of the said box A a disc B is provided, the said disc being kept
from contact with the box A by springs C. D, D, D are wearing pieces which
are placed in sets of three or other suitable number round the piston rod E, and
the said wearing pieces D are held in position by compressing segments F which are
pressed inwards by the springs G, the said springs bearing against the interior of
the box A. Pins or other suitable connections keep the wearing pieces D in their
proper positions with regard to the segments F. H is a disc against which the
compressing segments F rest, and when the whole is enclosed in a stuffing box as
seen at Fig. 3, the end of the box A and the disc H are held elastically between
the ends of the said stuffing box. J is a tube which is attached to the stuffing box
and which supports a lubricator K at its upper end, and to the base of the said
lubricator a small tube L is connected, the said tube L passing down through the
tube J.
M is a tube which is attached to the case A of the packing above described,,
and the said tube passes up freely within the tube J and loosely encloses the
tube L. This arrangement of tubing allows of a free entrance, of oil to the
packing, whilst it is not impeded from free movement with the vibrations of
the piston rod.
In this manner I obtain a packing which is of a springy and yielding nature,
whilst at the same time the lubricant is conveyed to the piston rod in a free and
effective manner, thereby enabling the engine to work with greater ease and
efficiency than heretofore.
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:
1
1. The combination of the ring B, springs C, wearing pieces D, segments F,
springs G, and disc H, substantially as and for the purposes set forth.
2. The combination of the box A, ring B, springs C, wearing pieces D, segments F,
springs G, and disc H, substantially as and for the purposes set forth.
3. The tube M attached to the case A, in combination with the tube J,
lubricator K, and tube L, substantially as and for the purposes set forth.

page_text: 4. The general arrangement, construction, and combination of the various parts
forming my improvements in or connected with apparatus for packing and.
lubricating piston and other rods, substantially as and for the purposes set forth.
