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 in writing, and on reference to the accompanying sheets of
drawings, that is to say :-
The object of my Invention and what it consists in, is, by a novel combination and
arrangement of metallic packing rings and a metallic packing spring, or springs, to
give to the said packing rings a double action, lateral and vertical, expanding them
to the walls of the cylinder and extending them apart to the flanges of the piston
or other apparatus, rendering the same steam air or water tight.
In carrying out my invention in practice, by one modification I make a packing
spring, or springs, by coiling bending shaping or otherwise manipulating one or more
rods strips or pieces of steel or other suitable material, in such a manner that some of
the coils bends or parts stand out or project from the remaining or other coils bends
or parts, either square or at an angle, the spaces between the projecting coils bends or
parts being filled by coils bends or parts of a smaller size. The projecting coils
bends or parts can be arranged singly or consecutively and on different sides or edges
of the packing spring, or all can be arranged on the same side or edge if desirable.
The packing spring can be made in one continuous length, or it may be put together
in parts or segments. The packing spring may also be made by coiling bending or
shaping two or more rods strips or pieces together and will then form a compound
packing spring.
The material from which my improved packing spring is made can be of any form
or section suitable for the purpose, and the spring when made can be of any desired
form in transverse section.
My improved packing spring can be used in part of the circumference of the piston
or other similar apparatus, and the remaining spaces can be occupied by filling up
pieces of any description; and two or more of the packing springs can be used
together. When this packing spring is placed inside the metallic packing rings and
the junk ring of the piston screwed down, the flanges of the packing rings acting
upon the coils bends or parts which stand out or project press the packing spring out

page_text: of its straight or parallel line, giving to it a reciprocating power which holds the
packing rings to the flanges of the piston, and it also expands them to the sides of the
cylinders or other apparatus.
By another modification I make the coils bends or parts of equal size and the edges
or sides of the packing spring straight or parallel. The inner faces of the flanges
of my improved packing rings are formed with a series of projections and hollow
spaces, the projections on the one packing ring are placed opposite the hollow spaces
on the other, the projections and hollow spaces may be made of a parallel angular
curved or other desired form. When the packing spring is placed inside the packing
rings and the junk ring screwed down the projections on the flange of one packing
ring press the spring into the hollow spaces of the other which gives to it the same
reciprocating power as in the first modification.
By another modification the projections are made separate from the packing rings,
and may be called "gluts" or pressure blocks; these can be attached to the packing
rings or to the packing spring as may be desired.
The action of this combination (when in position) and the results are the same as
described in the previous modifications.
My improved metallic packing rings can be made in two or more rings with the
flanges attached, or one packing ring of the required depth can be used, and one
or both of the flanges made separate or detached.

understood some examples of the various modifications of my improvements are
