PROVISIONAL SPECIFICATION.
Self Recording Apparatus to be connected with Ships' Indicators.
I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me by Captain Walter Edward Thompson, of Charleville
Road, West Kensington, London, Commander, at present on the high seas), to be
as follows :-
s
This invention relates to a self recording apparatus to be connected with ships'
indicators to register by means of a chart the orders given by the captain and
transmitted by the man at the indicator to the indicator under the control of the
engineer.
The indications are by means of an automatically working pen or pencil registered
upon a paper chart divided into hours and parts of hours so that each chart is a
daily record of the captain's orders, and which are shown upon the chart at the time
given.
The apparatus consists of a clock working a cylinder, which latter revolves once
in 24 hours. and upon which a clean chart is wrapped around daily. The clock
and cylinder with the marking instrument etc. are enclosed in a glazed case and
placed in any convenient position connected with the shaft of the indicator.

Self Recording Apparatus to be connected with Ships' Indicators.
I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Captain Walter Edward Thompson,
of Charleville Road, West Kensington, London, Commander, at present on the
high seas), 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 a self recording apparatus to be connected with ships"
indicators to register by means of a chart the orders given by the captain and
transmitted by the man at the indicator to the indicator under the control of
the engineer.
The indications are by means of an automatically working pen or pencil
registered upon a paper chart divided into hours and parts of hours to minutes so
that each chart is a daily record of the captain's orders, and which are shown upon
the chart at the time given.
The apparatus consists of a clock working a cylinder, which latter revolves
preferably once in twelve hours, and upon which a clean chart is wrapped round
twice daily. The clock and cylinder with the marking instrument etc. are enclosed
in a glazed case and placed in any convenient position connected with the shaft of
the indicator.

page_text: A suitable method of carrying the invention into effect is illustrated in the
accompanying drawings, in which
Fig. 1 is a side elevation of the self recording apparatus complete.
Fig. 2 a similar view of a slightly modified form of same.
Fig. 3 a view of the chart opened out, but partly broken away.
Fig. 4 is a side elevation showing a suitable way in which the slide D may be
actuated, and
Fig. 5 a sectional plan view of same.
Referring to Fig. 1, the chart A is mounted on the drum or cylinder B which
is caused to revolve preferably once every twelve hours by clockwork. Against
the chart A a marker or pencil C bears, such pencil being carried by a slide D
connected with the ordinary indicator, so that when the latter is actuated to
convey the required instructions to the engineer, the pencil or marker will be
moved up or down, and a complete record of all signals sent will thus be
produced on the chart. The chart is marked into divisions of time (hours,
quarters, and minutes) in one direction, and into divisions corresponding with the
different orders or instructions to be conveyed by the indicator in the opposite
direction, as will be seen in Fig. 3, and the heavy black line on such fig.
shows the record produced by the marker or pencil during the day.
The whole apparatus is enclosed in a suitable case E.

In Figs. 4 and 5 is shown a suitable mode of operating the slide D carrying
the marker or pencil C. The arrangement shown in these figures consists of a
wheel F over which a belt G passes, such belt also passing over a wheel operated
by the ordinary indicator, or being actuated therefrom in any other convenient
manner. On the shaft of the wheel F a pinion H is secured, and gears_with
a rack I secured to the slide D. It will thus be seen that when the ordinary
indicator is actuated wheel F will be caused to turn and pinion H revolving with
it will by engagement with the rack I move the slide D up or down.
The invention is not however confined to this mode of actuatimg the slide D, as
same may be operated in any other suitable manner.
It will be readily understood that the chart might be arranged to serve for a
longer or shorter period than twelve hours, in which case the speed of travel of
the chart would have to be correspondingly modified.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. The self recording apparatus for ships' indicators consisting in a suitably
divided chart mounted on a drum which is caused to rotate once in a given
time, in combination with a marker or pencil bearing on such chart and suitably
connected with the ships' indicator, substantially as specified.
2. The modified form of recording apparatus illustrated in Fig. 2, in which the
chart on which the record is to be marked is caused to unwind from one roller on
to another, or to pass right round two rollers, one of which is actuated so as to
cause the chart to travel at a given speed.
