IMPROVEMENTS IN MACHINES FOR WASHING AND CLEANSING CASKS
Year: 1884

page_text: We, GEORGE INSKIPP and JOHN MACKENZIE both of 62 Leadenhall Street in
the city of London, Engineers do hereby declare the nature of our invention for
IMPROVEMENTS IN MACHINES FOR WASHING AND CLEANSING CASKS to be as,
follows:-
.:
Our invention is an improvement on the machine patented by our senior partner
Robert Davison and Thomas Johnson on the 17th of May 1862 in which machine
the holder consisted of an inner frame containing a central shaft with right and
left scrow threads cut theron working through two nuts on, or connected, to two
discs or platforms, between which the casks in one, two, or more tiers are placed-
Our present invention consists in adding a third disc or platform midway or nearly
midway between the top and bottom discs so as more conveniently and effectually
to hold small casks in two tiers which has been found a difficulty in the original
machine, and we make this disc so as to slide a short distance along the central
shaft to accommodate its position to the length of the casks when the top and bottom
discs are screwed towards each other for the purpose of securing or fixing the casks,
and we make this middle disc in such a manner that it can easily be removed when
it is desired to cleanse larger casks in one tier.
COMPLETE SPECIFICATION.
I GEORGE INSKIPP and I JOHN MACKENZIE both of 62 Leadenhall Street in the
City of London do hereby declare the nature of our Invention for IMPROVEMENTS
IN MACHINES FOR WASHING AND CLEANSING CASKS and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement :-
Our invention is an improvement on the Machine patented by our Senior
Partner, Robert Davison and Thomas Johnson on the 17th of May 1862, in which

page_text: machine the holder consisted of an inner frame containing a central shaft with
right and left screw threads cut thereon working through two nuts on or connected
to two discs or platforms between which the casks in one or more tiers are
placed.
Our present Invention consists in adding a third disc or platform midway or
nearly midway between the top and bottom discs so as more conveniently and
effectually to hold small casks in two tiers, which it has been found difficult to do
in the Machine described in Davison and Johnson's patent and we make this third
dise so as to slide a short distance along the central shaft to accommodate its
position to the length of the casks when the top and bottom discs are screwed
towards each other for the purpose of securing or fixing the casks, and we make
this third or middle disc in such a manner that it can be easily removed when it is
desired to cleanse larger casks in one tier.
In the accompanying drawing Figure 1 is a Sectional Elevation of the Machine
in which A is the third or middle disc, the addition of which constitutes our
improvement. This disc is shewn in the position which it occupies when the casks
are held tightly between it and the top and bottom discs B and C, but, when the
discs B and C are screwed apart to release the casks, the middle disc A descends
or slides along the central shaft D until it rests on the collar E when the upper
tier of casks can be removed and when the disc C continues to descend, the casks
in the lower tier are left loose and can also be taken out and replaced.
Figure 2 shews a Plan of the disc A having a slot F which allows it to be lifted
out of the machine when it is desired to cleanse larger casks in one tier.
The other parts of the Machine are similar to those described in Davison and
Johnson's patent dated 17th May 1862.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
The addition of a third or middle disc to the machine described in Davison and
Johnson's patent dated 17th May, 1862, substantially as hereinbefore described so
as to render the machine capable of more conveniently and effectually holding small
casks in two tiers, which middle disc may or may not be made in such a manner
as to be casily removed from the Machine.
