PROVISIONAL SPECIFICATION.
Improvements in or relating to Hydraulic Lifts, Hoists, Cranes, and
the like....
I, THOMAS MULLOCK, of 71 Etta Street, Deptford, London S.E., Engineer,
do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to effect improvements in the application of
hydraulic power to lifts, hoists, cranes, and other analogous appliances.
According to my invention, I place the ram or plunger above the cylinder, and
bolt the same to the framing or other support, so that the ram is stationary
relatively to the cylinder; and I arrange the cylinder to rise and fall upon and.
below the ram or plunger, the cylinder being guided by parallel or other guides.
I fit the rising and falling pulley or pulleys for carrying the lifting or other chains
or ropes to a frame carried by rods attached to the cylinder; and other pulleys in
convenient positions for multiplying the speed, as required.
By the application of my invention, the descent of the cylinder, consequent upon
the hydraulic pressure, is augmented by the weight of the cylinder and the weight.
of the water contained therein.
* + 1
The passages for the water may he made to pass through the ram or plunger, or
through the cylinder, as found most convenient; in the latter case a tube being
fitted to slide telescopically in or on the supply pipe, or a flexible tube being used
for the same purpose.

Improvements in or relating to Hydraulic Lifts, Hoists, Cranes, and
the like.
I, THOMAS MULLOCK, of 71 Etta Street, Deptford, London S.E. Engineer, do
hereby declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of my invention is to effect improvements in the application of
hydraulic power to lifts, hoists, cranes and other analogous appliances.
According to my invention, I place the ram or plunger above the cylinder, and
bolt the same to the framing or other support, so that the ram is stationary
relatively to the cylinder; and I arrange the cylinder to rise and fall upon and
below the ram or plunger, the cylinder being guided by parallel or other guides.
I fit the rising and falling pulley or pulleys for carrying the lifting or other chains
or ropes to a frame carried by rods attached to the cylinder, and other pulleys in
convenient positions for multiplying the speed, as required.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing which illustrates one method
of carrying out my invention.

page_text: a is the ram or plunger placed above the cylinder 6 and secured to a fixed frame
or support c so that the ram is stationary relatively to the cylinder. The cylinder b
is provided with a guide frame or head d capable of sliding upon two or more
guide rods e e fixed to the ram support c at one end and to a similar frame ♫ at the
other end, the lower frame c' being formed with a central opening to act as a
guide to the cylinder.
The guide frame d is provided with two or more rods ff which pass through
suitable guides in the ram support c and carry the rising and falling pulleys g, as
shown.
By the application of my invention, the descent of the cylinder, consequent upon
the hydraulic pressure, is augmented by the weight of the cylinder and the weight
of the water contained therein.
The passages for the water may be made to pass through the ram or plunger, or
through the cylinder, as found most convenient; in the latter case a tube being fitted
to slide telescopically in or on the supply pipe, or a flexible tube being used for
the same purpose.
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 improvements in or relating to hydraulic lifts, hoists, cranes, and the
like substantially as described.
2. In hydraulic lifts, hoists, cranes, and the like, arranging the cylinder to rise
and fall upon and below a stationery or fixed ram or plunger, the cylinder being
provided with a suitable frame carrying the pulley or pullies and sliding in
suitable guides, other pulleys being fitted for multiplying the speed if required,
substantially as hereinbefore described.
