Improvements in Barrel Heads.
A communication by WILLIAM C. BLUNDELL and GEORGE PHILLIP DOLD,
both of Wichita, in the County of Sedgwick and State of Kansas, United
States of America.
I, GEORGE CECIL DYMOND, M.I. Mech. E., of The Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool and 6 Bank Street, Manchester both in the
County of Lancaster and 323 High Holborn in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention and in what manuer the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to certain novel structural features in an openable barrel
head and consists in an annular rim seated in the croze of the barrel bevelled at its
outer margin to perfectly fit said crozing and made with an annular depending
hollow or groove at its inner margin and provided, studded to its upper surface,
with a plurality of equidistant bevelled faced keepers adapted to be turned over, or
from, said annular hollow or groove, and of a trussed pressed metal cover
having a depending marginal flange adapted to be seated upon packing in the
annular hollow or groove of said rim and be forced down and locked upon its seat
packing by means of said keepers being turned to bring their hevelled faces to ride
upon the margin of said cover.
In the drawings B represents the barrel. R is the rim which is preferably made
of cast metal, but may be of pressed metal and is made with the annular groove G
depending at its inner margin, into the hollow of which groove is placed a suitable
packing material P. D represents the keepers each being made with a vertical
hole S through which the studs S are placed for attaching them to the rim R with
an extending slightly curved portion L bevelled laterally at its under side and with
an opposite extending foot portion D', which when placed bears against the surface
of the rim R to prevent the portion L rising too high.
The keepers thus constructed are placed about the rim R an equal distance
apart, where they are pivotally secured by securing the lower portion of their studs
in corresponding holes of the rim, as shown, and adjacent each stud S, made
integral with rim R, is a ledge C ranging crosswise of the rim and each being
provided with an upright shoulder C' at its outer end, which ledges are for the
purpose of forming a rest for the end portions L of keepers D to ride upon
when turned from the cover of the head, and the upright shoulders C₁ serve as
stops to prevent the keepers moving off the outer end of said ledges. E is the
head cover, preferably made of pressed metal with the depending marginal flange J
removably seated upon the packing P in groove G where it is firmly held seated,
subject to being released by turning the keepers D to bring their bevelled faced
end portions to ride upon the cover margin, as represented in Figure 1. The said
cover is preferably pressed to present a convex surface within the barrel and is
trussed across its outer concave surface to aid in preventing an inward pressure
effecting or changing its form by means of the bowed cross bar F held at each end
to the cover by means of rivets a a and by means of a strut I placed between said
bar and cover. The entire metal portions of the head are preferably galvanised to
prevent corrosion.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is-
1. The openable barrel head comprising the rim K provided with the annular
marginal groove G adapted to hold a packing material; the cover E provided
with the depending marginal flange adapted to be seated in said groove upon the
packing placed therein; and the keepers D studded to said rim and adapted
to be turned to ride upon the cover margin to thereby hold the cover seated
substantially as set forth.
2. The combination with a barrel, of the rim R seated in the croze of the barrel
and provided with the depending annular marginal groove G; the packing P
placed in said groove; the keepers D studded to said rim; and the cover E
provided with the depending marginal flange J adapted to be seated in said groove
upon said packing, and to be held thus seated by means of said keepers in the
manner substantially as and for the purpose specified.
