PROVISIONAL SPECIFICATION.
Registering Apparatus for Paper Making Machines.
I, CHARLES JOHN RICHARDSON, of Team Valley Paper Mills, Gateshead-on-
Tyne, in the County of Durham, Paper Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to apparatus for recording the length, breadth and quantity
of paper being made in any given time on the paper machine.
By its means the "output" of the said machine may at any moment be
ascertained in a few seconds instead of, as at present, by means of long and
elaborate calculation.
The apparatus consists of two small drums, one of which revolves ten times
faster than the other by means of suitable gear wheels which take their motion from
any convenient point on the paper machine. One revolution of the slow drum
corresponds to a definite length of paper made. Upon the drums are fixed tables
of "constants and in front of these are scales with sliding pointers to indicate the
width of paper being made.
"
"
Upon the apparatus being put in motion for a given number of seconds the
constants which appear next to the pointers indicate the "output of the machine
for a given time, while upon the druns the speed of the machine is also
registered.

I, CHARLES JOHN RICHARDSON, of Team Valley Paper Mills, Gateshead-on-

particularly described and ascertained in and by the following statement :-

DESCRIPTION OF THE DRAWING.
Figure 1 is a front view of the apparatus and
Figure 2 a plan view of the gearing only.
a is a pulley driven by band 6 off the paper machine and gives motion to worm c
which turns the worm wheel d on spindle e. To this spindle are fixed the drum f
and the gear wheel g. This gear wheel drives pinion h which is fixed to spindle i on
which is also fixed the gear wheel k, which again actuates the pinion / and with it
drum n. By this means drum n revolves ten times faster than drum f.
oo are scales indicating the widths of paper made on any given machine and p is
an adjustable pointer moving on screwed rod q.
Use is made of this registering apparatus in the following manner :-
:-The paper
machine being at work the registering apparatus is thrown into gear with it by
means of a conveniently arranged clutch and it is kept in gear for a prearranged
time which is such that even if the paper machine be running at its highest speed
the slow drum f does not make a complete revolution. It is convenient that the
complete revolution of the drum f should correspond to one hundred feet length of
paper produced so that the time for the registering apparatus to run should be such
that the output of one hundred feet linear in the interval is never exceeded. Exactly
as the time allotted to the run expires, the registering apparatus is stopped and the
figures can then be read from the tables. It is convenient that these tables should
be printed on paper, wrapped around the drums, and attached to them by paste
or otherwise.
The figures to be read from the drums after a run are those which appear next
to the scales o on either side; and of these figures two sets are to be noted. One set
of figures preferably those lowest down upon the drums indicate the linear measure-
ment of the paper the tens appearing on one drum and the units on the other. The
area of paper produced (expressed in reams of a given size) is read from the drums
at the two extremities of the pointer p and the one amount is to be added to the
other. The scale o is graduated from top to bottom according to the width of the
paper made on the machine, from the narrowest to the widest, and before the use of
the instrument the pointer p is set to the width of the paper which at the moment
is being made.
In preparing the instrument for use also the drums are set so that at the start
the indication is zero both of length and area.
After a run has been made the figures as to length width and area of paper
remain recorded in the instrument until it is reset ready for another operation.
The precise figures to be employed in the tables will vary according to the unit
ream which it may be found convenient to adopt for any particular paper
machine.
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 :-
A registering apparatus for a paper making machine in which are two drums
geared together to revolve at different speeds and a scale with a pointer which can
be traversed along the scale parallel to the axes of the drums and driving mechanism
whereby the drums may be driven for a prearranged time at speeds dependent on

page_text: that of the paper machine and tables upon the drums to shew the length and area
of paper produced and graduations upon the scale by which the pointer may be set
in accordance with the width of this paper; the whole so arranged that without
calculation the output of the paper machine can be ascertained and recorded
substantially as herein described.
