Complete Specification Left, 13th July, 1895-Accepted, 19th Oct., 1895
I, JOHN CHARLES ETCHELLS, of Heaton Chapel, uear Stockport, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows
This invention is designed to facilitate the construction of the apparatus and to
reduce the cost of same.
It consists essentially in constructing the intensifier with a hooded casting to form
the cross head connected to the outer cylinder by a clip ring or similar device without
the use of connecting pillars such as have been hitherto employed.
In carrying out the invention I construct the outer cylinder, the inner cylinder-
ram, and the stationary ram in the usual manner, but I dispense with the usual
flanged cross-head.
The upper edge of the outer cylinder form without any flange or lugs and
Recurately turn it leaving a space in the top edge to receive the cupped leather
packing. Instead of a cross head of the ordinary construction I provide a hooded
casting of atcel (or iron) to which the iuuer ram is attached at its outer end. This
casting at its lower end is provided with an annular base connected to the top part
or cross head by one, two or more legs. The annular base is turned to fit onto the
upper end of the outer cylinder and a projecting ring thereon fits into the cavity
provided for the packing and holds it in position. A rim is formed round the edge
both of the cylinder and the aunular base of the casting, and the two are firmly
held together by a clip, ring or other device with a bolt or screw to hold the parts
together.

COMPLETE SPECIFICATION.
Improvements in Hydraulic Intensifiers.
I, JOHN CHARLES ETCHELLS, of Heaton Chapel, near Stockport, in the County
of Lancastor, 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 :—
This invention is designed to facilitate and simplify the construction of the
apparatus.
It consists essentially in constructing the intensifier with a hooded casting to
form the cross head connected to the outer cylinder by a clip ring or similar
device without the use of connecting pillars such as have been hitherto
employed.
It will be fully described with reference to the accompanying drawings.

page_text: Fig. 4. Ilan of clip ring for connecting the hooded cross-head with the outer
cylinder.
I construct the outer cylinder A the inner cylinder ram B and the stationary
ram D in the usual way but I dispense with a flanged cross-head such as has
ordinarily been employed.
I form the outer cylinder A on its upper edge a without any flange or lugs and
nccurately turn it leaving a space a' in the top edge to receive the cupped leather
or other packing to make a joint with the cylinder ram B.
I attach to the outer end of the stationary ram D a hooded casting C of steel (or
iron) constructed with an annular base c connected to the upper part or cross-head
by one two or more legs or connecting pieces c. The annular base c is turned
to fit onto the upper end or edge a of the outer cylinder A and a projecting
ring thereon fits into the cavity a' provided for the packing and holds it in
position.
A rim or flange is formed round the contiguous edges of the cylinder A and
the annular base c of the casting C and the two are firmly held together by a
clip ring E or other device secured by bolt or screw e which holds the parts
together.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
.claim is :-
An hydraulic intensifier constructed with a hooded casting such as Cattached to
the stationary ram and connected to the outer cylinder by an annular base in
substitution for a cross-head substantially as described...
