PROVISIONAL SPECIFICATION.
Improved Apparatus to be employed for "Trimming" Sanitary Pipes.
We HEMAN COULTHURST, JESHURUN
COULTHURST, and ARMENA
COULTHURST all of Robert Street Foundry, Darwen in the County of
Lancaster, Ironfounders and Engineers do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus employed for "trimming" earthenware pipes
known as sanitary pipes, the object being to supply a ready means for adjusting
and finishing the rotary table, on which the pipes are trimmed at any height
required; our improved apparatus is of special utility where a turn over table is
e:nployed.
According to our invention the rotary table is mounted at the upper end of a
vertical spindle or shaft capable of vertical adjustment and provided with suitable
gear for actuating the same, for example a bevel or toothed wheel through which
the spindle, which is made with a groove or feather can slide.
To the lower end of the spindle is attached a plunger, piston head or plate
provided with a leather cup or other equivalent device capable of sliding in a
vertical hydraulic cylinder or tube in communication with a suitable head of water
controlled by a valve. By these means the "trimming" table can be set to any
required height according to the length of pipe required. For instance the
trimming" wheel table can be set at the exact height for receiving the pipes
from the turn over, and when "trimmed can be instantly lowered to level of
floor ready for carrying away. The said valve can also be adjusted so that any
size of pipe large or small can be counterbalanced and manipulated with equal
facility.

COULTHURST and ARMENA
We HEMAN COULTHURST, JESHURUN
COULTHURST, all of Robert Street Foundry, Darwen in the County of
Lancaster, Ironfounders and Engineers, 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 relates to apparatus employed for trimming earthenware pipes,
known as sanitary pipes, the object being to supply a ready means for adjusting
and finishing the rotary table, on which the pipes are trimmed at any height
required; our improved apparatus is of special utility where a turn over table is
employed.
Our invention will be clearly understood from the following description on
reference to the accompanying drawing which shews an elevation of our improved
apparatus.

page_text: According to our invention the rotary table a is mounted at the upper end of a
vertical spindle or shaft b capable of vertical adjustment and provided with
suitable gear for actuating the same, for example a bevel or toothed wheel c
through which the spindle b, which is made with a groove or feather or which is
otherwise equivalently formed can slide.
To the lower end of the spindle 6 is attached a plunger piston head or plate
provided with a leather cup or other equivalent device capable of sliding in a
vertical hydraulic cylinder or tube d in communication (through a pipe e or
otherwise) with a suitable head of water (such as the cistern e¹ and pipe e²)
controlled by the valve f. By these means the trimming table a can be set to any
required height according to the length of pipe required.
"
For instance, the trimming wheel table can be set at the exact height for
receiving the pipes from the turn over, and when "trimmed can be instantly
lowered to the level of the floor ready for carrying away.
It will be seen that this machine is equally adapted for large or small pipes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The combination with a trimming table mounted on a vertical spindle of a
plunger or plate at the bottom of the spindle capable of working in a hydraulic
cistern or tube in communication with a suitable head of water substantially as and
for the purposes hereinbefore described and illustrated by the annexed drawings.
