PROVISIONAL SPECIFICATION.
Improvements in Metal Casks, Drums, and the like.
I, HENRY HARINGTON LEIGH, Assoc. M. Inst. C.E., Fel. Ch. Inst. P.A.,
F. Í. Inst., practising as Phillips and Leigh, of No. 22, Southampton Buildings,
Chancery Lane, in the Administrative County of London, Engineer and Patent
Agent, do hereby declare the nature of this invention to be as follows, (a com-
munication from the Portland Cement-fabrik Saturn, of No. 18, Zippelhaus,
Hamburg, in the German Empire, Manufacturers): -
The present invention relates to improvements in metal casks, drums and the
ike, and the object of it is to make such receptacles more rigid and liquid tight
at the ends and where the periphery of the heads joins the sides or body of the
vessel.
The construction of the cask or drum, according to the present invention, is
characterised by the heads or ends being provided each with a strong rigid ring,
built up of several pieces of wood and secured to the outside of the head, which
ring forms a rim over or upon which the end of the cask may be bent, the head
being secured in the body by means of screws or the like inserted from the outside.
In constructing the cask with wooden heads, the said wooden rim, which is
secured on the exterior of the heads, serves for connecting together the individual
pieces of the heads and consequently ensures a strengthening and stiffening of
these heads to a greater degree than the cross bar employed with ordinary casks
for a like purpose. It further augments the tightness of the cask at the adjacent
parts of the cask body and heads, the head at this portion being of double thick-
ness by the addition of the wooden rim, so that the tightening surface is likewise
double.
The fastening of the wooden head with wooden rim in the sheet metal shell or
body is effected by bending the projecting sheet metal edge inwardly on to or
over the wooden rim without any further treatment, or by serrating or notching
it and bending it inwardly so that the teeth can be made to enter the wooden rini.
In addition the head may be fastened by screws or the like, penetrating into it
through the cask shell or body.
In contradistinction to the one-piece bent wooden ring now used for edging or
bordering the ends of sheet metal casks and drums my construction of wooden
rim composed of sawn pieces as a cask edge has for its purpose primarily, a reduc-
tion in cost, as even very small odd pieces of wood may be employed as com-
ponent parts, and moreover the wood has not to fulfil the special qualities or
conditions required of wood as used in the production of bent wooden bars for
the purpose of inserting same in a bent condition into the cask edge.
This invention is likewise suitable and well adapted for use with metal heads,
the wooden heads being simply substituted by a metal disc, on to which the
wooden rim is secured by means of nails, or the like inserted through the metal
disc into the wooden rim, and if necessary, in addition the metal disc may have
its edge turned up.
The metal head with the wooden ring secured thereto may be held in place in

the shell into the wooden ring, the cask shell edge being first bent on to or over
the wooden rim, as above described with reference to the wooden heads.

Improvements in Metal Casks, Drums, and the like.
I, HENRY HARINGTON LEIGH, Assoc. M. Inst. C.E., Fel. h. Inst. PA.,
practising as Phillips and Leigh, of No. 22. Southampton Buildings, Chancery
Lane, in the Administrative County of London, Engineer and Patent Agent, do
hereby declare the nature of this invention (a communication from the Portland
Cement-fabrik Saturn, of No. 18, Zeppelhaus, Hamburg, in the German Empire,
Manufacturers), and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
The present invention relates to improvements in metal casks, drums and the
like, and the object of it is to make such receptacles more rigid and liquid tight
at the ends and where the periphery of the heads joins the sides or body of the
vessel.
In order that the invention may be more fully understood by one skilled in the
art to which it appertains I will now proceed to describe the same in detail and
for that purpose reference is taken to accompanying sheet of drawings, wherein :
Figure 1 is a central section through the head part of a metal cask constructed
in accordance with the invention.
Figure 2 is a plan of Figure 1; and
Figure 3 shows a modification.
The construction of the cask or drum, according to the present invention, is
characterised by the heads or ends d (Figures 1 and 2) being provided each with
a strong rigid ring 9, built up of several pieces of wood and secured to the outside
of the head d, which ring a forms a rim over or upon which the end 6¹ of the cask
body b may be bent, the head d being secured in the body 6 by means of screws c
or the like inserted from the outside.
In constructing the cask with wooden heads, the said wooden rim a, which is
secured on the exterior of the heads by nails e, or the like, serves for connecting
together the individual pieces of the heads and consequently ensures a strength-
ening and stiffening of these heads to a greater degree than the cross bar or cross
bars employed with ordinary casks for a like purpose. It further augments the
tightness of the cask at the adjacent parts of the cask body and heads, the head
at this portion being of greater thickness by the addition of the wooden rim, so
that the tightening surface is likewise greater.
The fastening of the wooden head d with wooden rim a in the sheet metal shell
or body b is effected by bending the projecting sheet metal edge 61 inwardly on
to or over the wooden rim a without any further treatment, or by serrating or
notching it and bending it inwardly so that the teeth can be made to enter the
wooden rim. In addition the head may be fastened, as already stated above, by
screws c or the like, penetrating into it through the cask shell or body b.
In contradistinction to the one-piece bent wooden ring now used for edging or
bordering the ends of sheet metal casks and drums, this construction of wooden
rim composed of sawn pieces as a cask edge has for its purpose primarily, a reduc-
tion in costs, as even very small odd pieces of wood may be employed as component
parts, and moreover the wood has not to fulfil the special qualities or conditions

page_text: required of wood as used in the production of bent wooden bars for the purpose
of inserting same in a bent condition into the cask edge.
This invention is likewise suitable and well adapted for use with metal heads,
the wooden heads being simply substituted by a metal disc 9 (Figure 3), on to
which the wooden rim a is secured by means of nails f, or the like, inserted through
the metal disc g into the wooden rim a, and if necessary, in addition the metal
disc may have its edge turned up.
The metal head g with the wooden ring a secured thereto may be held in place
in the cask body b by means of screws c or the like inserted from the outside
through the shell b, into the wooden ring a, the cask shell edge 61 being bent on
to or over the wooden rim, as above described with reference to the wooden heads.
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:
In a metal cask, drum or the like, the combination of the sheet metal shell or
body with a wooden or metal head or heads and a bordering and strengthening
wooden rim or rims, composed of a series of sawn pieces of wood and secured,
together with the head to which the rim is fastened within the shell or body by
any suitable means, substantially as and for the purpose set forth.
Dated the 2nd day of February 1900.
