PROVISIONAL SPECIFICATION.
Improvements in Paper Making Machines.
We, JOHN DAVIDSON, of 23 Upper Thames Street, in the City of London,.
and COCHRANE KITCHEN, of Mugie Moss Paper Works near Aberdeen Paper
Makers, do hereby declare the nature of this invention to be as follows :-
:―
The object of this invention is to enable the machineman to run his machine at
full speed and to produce a close and perfect sheet of paper even when changing
from a pulp which parts with its water freely to a pulp which does not; or from a
thick to a thin sheet; and this without stopping the machine.
For this purpose the bearings of the breast roll and of the small rolls supporting
the gauze between the feed and the suction boxes in place of being fixed as is usual
are carried on a frame pivotted at its forward end and provided at the rear end
with means for raising and lowering it. By this means the height of the breast
roll relatively to the level of the gauze at the suction boxes can be varied so
varying the depth of the stream of pulp flowing on to the gauze.
Dated this 18th day of July 1895.

Improvements in Paper Making Machines.
We, JOHN DAVIDSON, of 23 Upper Thames Street in the City of London,.
and COCHRANE KITCHEN, of Mugie Moss Paper Mills, near Aberdeen, Paper
Makers, do hereby declare the nature of this invention and in what manner the
Bame is to be performed to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to enable the machineman to run his machine at
full speed and to produce a close and perfect sheet of paper even when changing
from a pulp which parts with its water freely to a pulp which does not; or from a
thick to a thin sheet;-and this without stopping the machine.
For this purpose the bearings of the breast roll and of the small rolls supporting
the gauze between the feed and the suction boxes in place of being fixed as is usual
are carried on a frame pivotted at its forward end and provided at the rear end
with means for raising and lowering it. By this means the height of the breast
roll relatively to the level of the gauze at the suction boxes can be varied so
varying the depth of the stream of pulp flowing on to the gauze.

page_text: the return branch of the gauze passes. All these parts are of ordinary and well
known construction, and require no further description.
e is a frame pivotted at fand supporting the frame carrying the above mentioned
parts (other than the feed trough) by adjustable standards g. The other end of
the frame e is supported on screws h whose upper ends carry bevel wheels; gearing
with the bevel pinions k on the horizontal shaft which carries the hand wheel m
so that by turning the latter the frame e and other parts are raised or lowered.
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 :-
1. Supporting the rolls b and c on a pivotted frame.
2. Paper making machines substantially as described and shown in the
drawings.
