Improvements in Steam Pile Drivers.
JAMES GARVIE Junior of 172 Fenchurch Street in the City of London Engineer
do hereby declare the nature of this invention to be as follows:-
A method of constructing a single action Steam Pile Driver by which the steam
pipe is stationery and does not move up and down with the monkey. In my Pile
Driver the Piston rod is of the shape of the letter and is hollow the lower end of
the Piston rod rests in the top of the Pile the top end of the Piston rod carries the
Piston. On the end of the horizontal part of the Piston rod is fixed the three way
cock or valve and the steam is passed through this valve and through the Piston rod
both in the horizontal and vertical portion and discharges between the top of
the piston and the under side of the cover of the Monkey, thus raising the Monkey."
The exhaust is worked by reversing the cock or valve in the ordinary manner.

LIZ Fenetren Street London .. Engineer 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 :-
My Steam Pile Driver consists of a Cylinder with Piston & Piston rod as hereafter
described and shown in the accompanying drawing.
In the drawing A is the Cylinder or Steam monkey B & C is the Piston rod D is
the valve and E is the piston. To work my Pile driver I place the Monkey in the
top of the Pile the Piston rod B sustaining the weight when working.
Steam is admitted at the cock B which is a 3 way cock through the interior of the
hollow piston rod B C. and escaping at the top of the piston E. The pressure being
between the top of the Piston E and the cover of the Steam Monkey the monkey is
raised and gives its upward stroke. The lever is then reversed and the 3
is made to exhaust and the monkey falls on the top of the Pile
way cock
In this system the flexible tube is connected to the Piston rod and is practically
stationary.
Having now particularly described my invention and the manner in which it
is accomplished I claim.
The arrangement of hollow Piston rod as shown and described by which the steam
pipe is connected to the Piston Rod.
