HAVELOCK CHAPMAN of Augusta Villa, Boleyn Road Forrest Gate London
Mechanical Engineer, do hereby declare the nature of our said invention for
"IMPROVEMENTS IN PACKING. FOR STUFFING BOXES" to be as follows:-
The object is to provide a resilient and durable packing adapted to allow efficient
lubrication in the stuffing boxes of steam, bydraulic gas air and fluid motors and
pumps.
Packing under our invention consists essentially in the employment in com-
bination of cane as a core or backing and asbestos or other fibrous material as
a wearing surface. We prefer in practice to use strips of cane plaited or braided
to form a tube or laid side by side longitudinally or spirally with an envelope or
wearing surface of asbestos, bemp or fibrous material the latter being plaited
braided or lapped.
Each cane strip is in some cases coated with asbestos, hemp or other fibrous
material before being plaited or braided. The covering or envelope for such strips
may be plaited braided seized or wrapped helically or spirally around the said core
according to circumstances or such covering may be laid longitudinally at one sidé
and be bound to the core by cords or a suitable tie.
Instead of employing a cane core or -backing in the form of a tube surrounded
by a wearing material, such cane core backing may be in the form of a plaited or
braided strip and it may be surrounded in part only say on one face by the
wearing materials.
It is found that the hollow cane core provides an excellent space for holding oil
or other lubricant and allowing such lubricant to pass freely to the wearing
surface.

"IMPROVEMENTS IN PACKING FOR STUFFING BOXES" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
The object is to provide a resilient and durable packing adapted to allow efficient
lubrication in the stuffing boxes of steam hydraulic, gas air and fluid motors and 1
pumps.
Packing under our invention consists essentially in the employment in com-
bination of cane as a core or backing and asbestos or other fibrous material as
a wearing surface. We prefer in-practice to use strips of cane plaited or braided
to form a tube or laid side by side longitudinally or spirally with an envelope or
wearing surface of asbestos, hemp or fibrous material the latter being plaited
braided or lapped.
.
Each cane, strip, is in some cases, coated with asbestos, hemp or other fibrous
material before being plaited or braided. The covering or envelope for such strips
may be plaited braided seized or wrapped helically or spirally around the said core
acccording to, circumstances or such covering may be laid longitudinally at one side
and be bound to the core by cords or a suitable tie.
1.
Instead of employing a cane core or backing in the form of a tube surrounded
by a wearing material, such cane, core backing may be in the form of a plaited or
braided strip, and it may be surrounded in part only, say on one face by the
wearing materials.
It is found that the hollow cane core, provides an excellent space for holding oil
or other lubricant: and allowing such lubricant to pass freely to the wearing

with fibrous material b.
It will be obvious that packing may be made in a multitude of forms by the
combination of cane and fibrous material under our invention.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. The combination of cane and fibrous material for packing substantially as
herein setforth.
Second. Packing composed of a cane core or backing and a wearing surface of
fibrous material.
