DTMFICATION,
I WILLIAM BUCKLEY of Millsands Sheffield in the County of York Engineer
do hereby declare the nature of the said Invention for IMPROVEMENTS IN
METALLIC PACKING RINGS FOR PISTONS PUMP BUCKets, Valves and FOR OTHER
SIMILAR PURPOSES 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 being had to the accompanying Sheet of explanatory
Drawings, that is to say :-
This Invention relates to certain new and useful improvements in the
manufacture or construction of rings for pistons pumps valves or for other
similar purposes, its object being the production of rings that will be more durable
and accurate in working and more efficient where high or low pressure steam, or air
water or other motive power is used, than the rings hitherto used.
According to one method of carrying out my Invention in practice, I make a
ring the whole breadth (or nearly so) of the distance between the flanges of the
piston, instead of making and using two or more rings as generally adopted. On
one edge of this ring on its inner side there is a flange or inner ring, the inner surface
of which flange or inner ring may be either of a parallel angular circular curved
or of any other desired and suitable form; the flange or inner ring can be made as
part of the broad ring, or it may be made separately if preferred and attached to it
by means of pins or screws, or in any other suitable way; a loose flange or inner
ring similar to the above can be placed at the other edge of the ring.
According to another method both flanges or inner rings can be arranged to be
loose and neither of them attached to the broad ring, the spring of the piston
acting on the inner surface of the flange or flanges of the inner ring or rings will
extend the broad ring to the side of the cylinder at the same time forcing the
flange or flanges or inner ring or rings against the flanges of the piston, thus
giving both a lateral and a vertical action, which result has not heretofore been
accomplished where one broad ring has been used.
The rings being made in one breadth, instead of in two or more breadths as
generally used, are much stronger, will keep in a parallel position while working,
they do not cant or twist, and they will act effectively in all cases where either
high or low pressure motive power is used.
The rings can be made of either cast wrought or malleable iron steel brass or of
any other suitable material, and the flanges or inner rings may be fitted to the
broad ring in any desirable and convenient way, by parallel shouldered bevilled or
circular or curved surfaces.

page_text: Figure 1, on the accompanying Sheet of Drawings represents a plan and
Figure 2, a sectional elevation of a broad ring a, having an inclined or bevilled
flange b, on the inside at one edge; at the other edge on the inside is a loose ring c,
also having an inclined or bevilled edge.
Figure 3, shows a section of a broad ring with a parallel flange at one edge d,
and at the other edge a loose parallel ring e.
Figure 4, shows in section a similar broad ring with a loose bevilled ring f, at
one edge.
Figure 5, shows a section of a plain broad ring with a loose bevilled ring g, g, at
cach edge.
Figures 6, and 7, show sections of broad rings h, bevilled on the inner edges i, i,
to fit the bevilled surfaces of the two inner rings.
"
Figure 8, shows in section a broad ring j, with a bevilled flange k, on the inside
at one edge with a loose bevilled ring with a flange l.
Figure 9, shows in section a broad ring with a bevilled flange m, on the insido at
one edge, and a loose parallel ring n, with a bevilled flange at the inner edge o.
Figures 10 and 11, show in section broad rings with bevilled flanges on the
inside at one edge p, and bevilled at the other edge to fit the inner bevilled
rings q.
Figure 12, shows in section a broad ring with a small inner flange r, at one edge
forming a shoulder to fit the inner ring, with a loose bevilled ring 8, at the other
edge.
Figure 13, shows in section a broad ring with flange having an inner circular or
curved surface t, at one edge, and an inner ring with a circular or curved surface u,
at the other edge.-And,
Figure 14, shows in section a broad ring with a bevilled flange v, on the inside
at one edge.
It may here be observed that Figures 3 to 14, show only some examples or
_modifications of the bevilled flanges or bevilled rings that can be used in the
manufacture of my improved rings, but it will be evident to the practical engineer
that other variations or modifications may be made therein and will answer the
same purpose equally as well.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I wish it to be
understood that I do not confine or limit myself to the precise details of my
improvements as herein described and illustrated on the accompanying Sheet of
Drawings, becauso numerous modifications or variations, it will be evident, may
be made therein without departing or deviating from the principles or main
features of my Invention; and in conclusion I declare that what I claim is :-
The manufacture or construction of improved rings for pistons pumps valves and
for other similar purposes, in which an outer broad ring with an inner flange at
one edge is arranged fitted and used; or an outer ring and one or more inner rings
are arranged fitted and used in combination, and giving both a lateral and a
vertical action; all being constructed and arranged or applied substantially as
hereinbefore described and as illustrated on the accompanying Drawings.
