COMPLETE SPECIFICATION.
Improvements in Vent Pegs.
1, WILLIAM WILLMETT, of No. 51, Beulah Grove, Windmill Road, Croydon,
in the County of Surrey, Carpenter, 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:—
The invention relates to improvements in vent pegs, and the objects of it are to
produce one which shall be at once automatic in its action, not liable to damage
when the empty barrel is being removed before the peg has been taken out of it or
driven into it flush with its surface, adapted to be always in the bung, and cheaper
than the automatic pegs hitherto offered.
In order that the invention and the means by which it is to be carried into
practical effect may be thoroughly understood; I will now describe it and them in
detail, referring in so doing to the accompanying drawings which are to be taken as
part of this Specification and read therewith.
Fig. 1 is sectional longitudinal elevation through a stave, bung and peg,
shewing the internal construction of the latter.
Fig. 2 is a sectional longitudinal elevation through a stave and bung, shewing the
external conformation of the peg.
Fig. 3 is a plan.
Fig. 4 is a side elevation of a barrel to which the present invention has been
applied. Portions of three staves have been broken away to shew the penetration
of the peg into the barrel.
Fig. 5 is a sectional longitudinal elevation illustrating a modification..
a is the barrel. b is the barrel bung. c is a short tube of any hard material,
preferably of metal or wood. It is from one to two inches in length according to
the size of the barrel. The shorter the tube is, the more rapid is the action of the
peg. d is a pervious core of soft fibres spun and twisted. They must not be spun
or twisted more tightly than is shewn in Figure 1 or air will not pass down a
freely as my invention requires. If they are spun and twisted less tightly the core
will answer. A core is about half the length of a tube.
The coro described in the preceding paragraph may be replaced by a pervious
pluge of felt or flannel. Fig. 5 illustrates its relative texture and thickness.
When the tube c is made of metal, its nose is sharpened as indicated in
Figures 1, 2, 3 and 4, for the purpose of adapting it to serve as a punch for
punching its own plug e. f is a flange upon the top of the tube. This flange is not
an essential part of the invention and may be dispensed with.
When the barrel is empty the peg is pushed down till its top is flush with the
barrel. This position of the peg is illustrated in Figures 2 and 4. And even if
the peg is not pushed in before the barrel is rolled away, the act of rolling the
latter over the ground will not smash the peg, because the projection of it beyond
the barrel is not too much for it to be forced by contact with the ground into its
hole instead of being pressed to one side of the hole and broken off.
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
1 The combination of tube and nervious core, as set forth.
