Improvements in Packing for Engine and other Glands
We SAMUEL WHITTAKER of 10 Collyhurt Street Manchester Traveller
and GFORGE HENRY RICHMOND of ɔ Derby Street Moss Side Manchester
Mechanical 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 has for its object the manufacture of a packing for engine and
other glands which shall make a tight joint with the minimum of function
is to form a
In carrying out our invention we construct a hollow spiral core of brass or other
suitable wire and on the outside of this core we plait hemp asbestos or other
suitable material previously soaked in lubric int in such a manner
square or other section as desired We further fill the hollow spiral core with
lubricant and so form a packing which makes a tight joint with very little pressure
And in order
upou the gland and retains its lubricating properties for a long time
that this our sud invention may be the more readily understood and carried into
effect we have hereunto annexed a sheet of drawing illustrative of the same which
we will now proceed to explain with the assi tance of the various figs and letters
of reference marked theieon Eig is a section and Fig 2 an elevation of ou
improved paching A is a hollow spi al core of briss or other untable wire which
ustible
we prefer to fill with lubricant b, and C is the hemp a bestos or othe
maternal pluted over the core A the whole forming a packing which is found in
practice to make tight joint with very little friction
Having thus putically de cubed and ascertumed the nature of the ou sud
invention together with the bet method with which we are acquainted for carrying
the same into practical effect we wish it to be understool that we do not confine

page_text: ourselves to the use of any particular lubricant for filling the core nor to any
particular material for plaiting over such core and although we only illustrate a
square section it will be obvious that round oval or any other section may be used
or that more than one core may be plaited in the material but what we do
claim is
The use and application of a hollow spiral core to packing for engine and other
glands substantially as herein before described and illustrated on the accompanying
drawing
