Improved Triangular Packing for Stuffing Boxes of Steam and
other Fluid Pressure Engines with Adjustable Metal Rings in
Stuffing Boxes.
SAMUEL LAMONT, Marine Engineer, 179 Sandyford Street, (West,) Glasgow, and
CHARLES LAMONT Esq., Marine Insurance Broker, Royal Exchange, Glasgow, do
hereby declare the nature of this invention to be as follows :-
Improved Triangular Packing. This Invention as claimed is the application of
triangular packing composed of canvas, and India Rubber core or solid compressed
vulcanized canvas, or asbestos similarly treated alternately with metal, triangular
rings.
With the important addition of a metal neck ring less diam: than the stuffing box
capable of being let together from time to time as required, to prevent the escape of
pressure through the packing, as the bushes in the covers and glands wear.
Also the packing about to be manufactured is highly vulcanized to harden when ia
use forming a perfectly metallic surface where exposed to friction.
This packing can also be used without the triangular metal rings (retaining at
option the metal neck ring) by reversing the packing every alternate turn.
Dated this 3rd day of February 1887.

Glasgow 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 invention claimed is the application of triangular packing composed of Canvas
and India-rubber core, A Fig. 1. or solid compressed vulcanized canvas or asbestos
similarly treated B Fig. I. alternately with metal triangular rings C. Fig. I.
:
With the important addition of a metal neck-ring less diam than the stuffing box
capable of being let together from time to time as required, to prevent the escape of
.pressure through the packing as the bushes in the covers and glands wear, D. Fig. I.
Also the packing about to be manufactured is highly vulcanized to harden when in
use forming a perfectly metallic surface where exposed to friction.
s
This packing can also be used without the triangular metal rings (retaining at
option the metal neck-ring) by reversing the packing every alternate turn E. Fig. II.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is
1st. The Triangular form of said compressed canvas and asbestos packing.
2nd. The adjustable neck-ring applied with the said packing.
3rd. The economy derived from its use, only one half of the packing being in
contact with the piston rod, every alternate turn being neutral.
