Improvements in or connected with Pistons and Gland Packings.
I, HARRY WORMALD, of Featherstone, near Pontefract, in the County of
York, Engineer, do hereby declare the nature of this invention, to be as
follows:-
My invention has reference to improvements in or connected with pistons and
gland packings, whereby the rings can be adjusted to fit the cylinders and stuffing
boxes, so as to prevent slips of steam, water or other fluids past the rings.
According to my invention the outer rings are made cone shaped on the under
side, and cones are made to fit them and to be adjustable.
The packing plates can be made any number to suit the degrees of adjustment.
My said improvements can be fixed to any existing cylinder without any
alteration to the cylinder body.
By my invention all piston or gland rings can be adjusted so that they are
equally as efficient, when almost worn out, as they are when put in new.

DESCRIPTION OF DRAWINGS.
Fig. 1, is a section of piston showing my invention applied as when new.
Fig. 2, is a further section showing the adjustment of the parts.
In applying this invention to glands the same principle and construction applies,
the packing is reversed and rings A are applied to the working surface or piston
rod. A are the outer rings made cone shaped on the under side, B are the cones
made to fit the under sides of the outer rings A, and to be adjustable.

page_text: C are the packing plates by means of which the position of the cones B can be
adjusted to suit the wear.
In Fig. 1, the packing is shown as when first applied, or when new. As the
outer rings A wear, the cones B are adjusted by separating them, and interposing
or placing between them, the packing rings C taken off each side, so that, the
adjustment is gradual, and the outer rings A can be utilized to their full
extent.
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
A packing, for pistons and glands, having the outer rings A cone shaped on their
under sides, with cones B and packing rings C, arranged substantially as and for
the purposes set forth.
