Newcastle-on-Tyne, for the Invention of "IMPROVEMENTS IN PILLAR
CRANES."
Sealed the 18th September 1866, and dated the 20th March 1866.
PROVISIONAL SPECIFICATION left by the said Percy Graham Buchanan
Westmacott at the Office of the Commissioners of Patents, with his
Petition, on the 20th March 1866.
I, PERCY GRAHAM BUCHANAN WESTMACOTT, of Elswick, Newcastle-on-
Tyne, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN PILLAR CRANES," to be as follows:-
This Invention has for its object improvements in pillar cranes.
structing a pillar crane worked by hydraulic power in place of having the
hydraulic cylinder and ram separate from the crane the hydraulic cylinder is
formed or placed within the pillar, and the ram moves up and down within
such cylinder, by which means hydraulic pillar cranes are made self-contained,
occupying less space, and are more economical in their construction. Tho
water pipe is introduced through the step or bottom bearing into the lower
end of the pillar. In order to increase the range of the lifting chains multi-
plying pulleys are used, the arrangement of which may be varied and depend
on the particular circumstances under which a crane of this construction is
required to be used. Ordinarily for moderate lifts one end of the chain is fixed
to the pillar of the crane and then passes over the pulley carried by the upper
end of the ram, thence it passes under a pulley carried by the upper end of

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PERCY
GRAHAM BUCHANAN WESTMACOTT, of Elswick, Newcastle-on-Tyne, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Percy Graham Buchanan Westmacott, Her special licence that I, the
said Percy Graham Buchanan Westmacott, my executors, administrators,
and assigns, or such others as I, the said Percy Graham Buchanan West-
macott, my executors, administrators, and assigns, should at any time agreo
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
send, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN PILLAR
CRANES," upon the condition (amongst others) that I, the said Percy
Graham Buchanan Westmacott, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of tho said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Percy Graham Buchanan Westmacott,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :--
In con-
This Invention has for its object improvements in pillar cranes.
structing a pillar orane worked by hydraulic power in place of having the
hydraulic cylinder and ram separate from the crane the hydraulic cylinder is
formed or placed within the pillar, and the ram moves up and down within
such cylinder, by which means hydraulic pillar cranes are made self-contained,

page_text: occupying less space and are more economical in their construction. The
water pipe is introduced through the step or bottom bearing into the lower
end of the pillar. In order to increase the range of the lifting chains multi-
plying pulleys are used, the arrangement of which may be varied and depend
on the particular circumstances under which a crane of this construction is
required to be used.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
The water pipe is introduced through the step or bottom bearing C of the
pillar and into the lower end of the pillar and hydraulic cylinder A. Ordi-
narily for moderate lifts one end of the lifting chain E is fixed to the pillar A,
and then passes over the pulley F carried by the upper end of the ram B;
thence it passes under a pulley placed near the foot of the jib D to a pulley
fixed at the outer end of the jib.
When it is desired to increase the range of the lifting chain multiplying
pulleys are introduced between the pulley F attached to the end of the ram B
and the pulley or pulleys at the foot of the jib D, as is shown in the Drawing;
this arrangement may be varied to suit the particular circumstances under
which a crane of this construction is required to be used. When the crane is
turned by water power cylinders, and rams are introduced for this purpose, as
shown at H, but to which no claim is made. The pump valves and gearing are
of the ordinary construction, and being well understood require no description.
The pillar A may be made of any suitable material, and may be formed either
to serve as the bydraulic cylinder and pillar in one piece, or as is preferred to
be the case in constructing large and powerful cranes the pillar A may be
formed to receive the hydraulic cylinder, the two being joined into one.
The peculiarity of this Invention consists in constructing pillar cranes with
pillars formed to receive hydraulic rams, or to receive bydraulic cylinders and
rams, as herein described.
In witness whereof, I, the said Percy Graham Buchanan Westmacott,
have hereunto set my hand and seal, this Twelfth day of September,
in the year of our Lord One thousand eight hundred and sixty-six.
