I DONALD FERGUSSON of Her Majesty's Dockyard, Portsmouth, in the County

My reasons for making this amendment are as follows:-
.It is doubtful whether the claims are not in too general a form and consequently
include matters which were not novel at the date of the said patent and are other-
wise unintelligible as to what is the invention described and intended to be claimed
and that said claims may be construed in a sense substantially different from or
the reverse of the meaning I intended to convey thereby and to correct certain
clerical errors.

page_text: In the Matter of an Application by Donald Fergusson for leave to amend the
Specification relating to his Application for Letters Patont N° 12,286 of 1885:
I hereby grant leave to the above named Donald Fergusson to amend the said
Specification in the manner proposed.

page_text: I, DONALD FERGUSSON, of Her Majesty's Dockyard, Portsmouth, in the County
of Hants, Clerk of the Works, do hereby declare the nature of my invention for
IMPROVEMENTS IN WATER METERS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
In order that my improvements may be the better understood, I have appended
bereto a drawing of the same of which Fig. 1 represents a plan view, Fig. 2 a
front sectional. elevation, and Fig. 3 a cross sectional elevation of parts of such
apparatus.
In carrying out these improvements I employ a balance (a.) working upon a
rocking gudgeon (a¹), over the partition (c.), separating the two chambers (d.),
which are of equal proportions and known capacity. The balance (a.) which will
be confined in its action to a given radius by seatings (e.) projecting from the
sides (e) of the chambers (d.) is formed with racers (a2), for the weights (b.), which
are cylindrical and preferably coupled as (b) so as to insure simultaneous movement
in such alternate manner, that, whilst one is moving towards the centre (a¹)
where it will remain for the time dormant, as (45) (62) holding the levers (k.) in
position; the other is moving towards the ends (a³) where it will remain for the
time as a counterpoise as (63), until both are reversed by the action of the lever
floats (f), upon the sheaves (g.), on the under side of the balance (a.).
The lever floats (f.) to be of sufficient power to lift the weights (b.) as at (6³)
over the centre, and these weights sufficient to counterpoise the head of water over
the valves (h.) as at (¹), when the float levers cease to act and the valves of the
chambers as at (¹) are opened as described, and the contents discharged into the
regulating tank (l.) at (1). The supply pipe.(i.) being flexible at the point (¹)
and the weights (b) in turn arriving at the centre as (63) (6²), impinge upon the
levers (k.) which are attached and suspended to the rocking gudgeon (¹) which is
cranked at (2) and attached to the supply pipe at (22), the supply is shunted
upon the partition (c) at (c¹) and the chambers (d.) are thus charged and discharged
alternately.
The weight valves (h) have their rods (h³) connected with the balance (a.)
at (a), for which their upper ends have slides (h³) which are regulated in length
to a proportion of the necessary radius of the balance (a.), so that the valves (h)
are not lifted until the weights (b.) take the return charge of the balance (a.).
The supply pipe (i.) passes through a regulating or store cistern as at (3) which
cistern may be attached as (L.) or may be placed at a lower level in any part of the
building, but in any case the ball-cock arrangement attached to the supply pipe (13)
will be placed in it.
The overflow will be regulated so as to admit of one or two extra charges from
the apparatus before being brought into use, so as to prevent waste.
The index arrangement may be actuated by the rocking gudgeon (a¹) at (a³).

page_text: Having thus described my invention, and means by which the same is carried
into effect, I would have it understood that I make no claim separately considered
to any portion of the invention described in my complete specification accom-
panying my application for Patent No 12,285 lodged concurrently with the present
one but that, what I do claim is the arranging or combining parts not-described-in
another-specification-submitted-at-the-same-time-and-date,-and-being-the-same-title
which-is-marked-N° + of water meters substantially as herein set forth in which :-
1st The-action-of The float levers act upon the balance se-as to put the weights
in motion.
2nd The--action--of The balance acts upon the valves, also and with their
attachments operute as set forth.
DONALD FERGUSSON.
