Complete Specification. Left, 13th. Mar., 1895-Accepted, 13th Apr., 1895
I, JOSEPH JOHN TYLOR, of 2 Newgate Street, in the City of London, Associate
Member of the Institution of Civil Engineers do hereby declare the nature of the
said invention to, be as follows:-
In certain kinds of meters in which the quantity of liquid passing is measured
by a rotating fan, or other similar instrument, the casing of the meter is so made...
and arranged that when the registering mechanism or clockwork is put in place.
therein it is not possible to see it during the process of testing to ascertain whether,
such mechanism or clockwork is working properly, or whether it is properly
connected with the spindle of the fan or other actuating part, and consequently. it
frequently happens that the meter has to be tried over and over again before its
proper working can be verified, especially as to the passage of small quantities of
liquid. The chief object of my present invention is to provide means whereby
the proper connection of the registering mechanism or clockwork with the actuating
part can be verified, before the casing is put together and, as far as the passage of
small quantities of liquid is concerned, whether the said mechanism or clockwork
is working properly.
For this purpose I construct the lower part of the casing of the meter, which
contains the rotating fan and the inlet and outlet passages shallower than heretofore,
and the upper part containing the registering mechanism or clockwork corre-
spondingly deeper, making the joint between the two at such a point that when
the upper part is removed, and the registering mechanism or clockwork is in place
it is wholly exposed to view above the aforesaid joint, so that every part of it, .
together with the central portion of the rotating fan, can be seen or watched by
the workman before and while the test for a small flow of liquid, not involving any
material pressure in the meter, is being made; but of course when the test for
larger flows, involving pressure in the meter, has to be made the upper part of the
case has to be put in place; as however the proper conuection of the registering
mechanism or clockwork with the actuating part, and the proper working of such
mechanism or clockwork, will have been previously verified during the test for
small flows of liquid it will be certain that such connection and working will be.
correct for the larger flows.
In the above described arrangement the inner casing heretofore used in.
accordance with the Specifications of my Patents No. 10,443 of 1885 &.No. 14,652
of 1887 may be dispensed with, but the brake arrangements, and the alternating,
projections or fillets and hollows or grooves, therein referred to may preferably be.
retained. The arrangement also enables me to make the meter more compact and,
of less weight than heretofore.

I, JOSEPH JOHN TYLOR, of 2 Newgate Street, in the City of London, Associate
Member of the Institution of Civil 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:-
In certain kinds of meters in which the quantity of liquid passing is measured
by a rotating fan or other similar instrument the casing of the meter is so made
and arranged that when the registering mechanism or clockwork is put in place
therein it is not possible to see it, during the process of testing, to ascertain whether
such mechanism or clockwork is working properly, or whether it is properly
connected with the spindle of the fan or other actuating part, and consequently
it frequently happens that the meter has to be tried over and over again before its
proper working can be verified especially as to the passage of small quantities of
liquid.
The chief, object of my present invention is to provide means whereby the
proper connection of the registering mechanism or clockwork with the actuating
part can be verified before the casing is put together and, as far as the passage of
small quantities of liquid is concerned, whether the said mechanism or clockwork
is working properly.
And in order that the said invention may be fully understood I will now proceed
to describe the same with the aid of the accompanying two sheets of drawings in
which Figure is a vertical section of a meter with my improvements applied
thereto, Figure 2 a partial vertical section of the same meter taken on a radial
line passing through one of the pillars supporting the clockwork in the case,
Figure 3 a vertical section of a similar meter with a somewhat different arrangement
for supporting the clockwork in the case, Figure 4 a separate view of the said
support for the clockwork, and Figure 5 a plan showing a method of fixing the
clockwork on the support shown in Figure 4.
1 construct the lower part A of the casing of the meter which contains the
rotating fan B and the inlet and outlet passages C and D respectively shallower
than heretofore, and the upper part E containing the registering mechanism or
clockwork correspondly deeper, making the joint between the two at such a
point F that when the upper part E is removed and the registering mechanism or
clockwork is in place it is wholly exposed to view above the aforesaid joint F, 80
that every part of such registering mechanism or clockwork, together with the
central portion of the rotating fan B, can be seen or watched by the workman
before and while the test for a small flow of liquid, not involving any material
pressure in the meter, is being made; but of course when the test for layer flows,
involving pressure in the meter, has to be made, the upper part E of the case has
to be put in place; as however the proper connection of the registering mechanism
or clockwork with the actuating part, and the proper working of such mechanism
or clockwork will have been previously verified during the test for small flows of
liquid, it will be certain that such connection and working will be correct for the
larger flows.
In the above described arrangement, the inner casing heretofore used in
accordance with the Specification of my Patent No. 10443 of 1885 and No. 14652
of 1887 may be dispensed with, but the brake arrangements and the alternating
projections or fillets and hollows or grooves therein referred to and shown
respectively at H, I and J in the drawings accompanying this Specification may
preferably be retained. The arrangement above described also enables me to
make the meter more compact and of less weight than heretofore.

page_text: In Figures 1 and 2 the frame K for the registering mechanism or clockwork is
shown supported by pillars L resting on the brake plate H and fitting snugly
within the rim or flange H¹ of the said plate, but a preferable means of supporting
the said frame K is that shown in Figures and 4 in which M is a cylindrical
cage on the lower part of which is formed the brake H and the upper part of
which is provided with openings N through which the proper connection of the
registering mechanism with the worm P on the spindle of the fan B can be verified.
A flauge Q on the cage M takes into a recess in the lower part A of the casing
and the joint F is made on such flange as shown in Figure 3 whereby the supporting
cage is securely fixed in place. In order to secure the frame K of the clockwork
on the supporting cage M the lower plate of the said frame rests on the fillet or
flange R in the said cage, and two notches S cut in the edge of the lower plate K
are passed over two studs T fixed in the cage M, and the frame K is then turned
so that the said notches no longer coincide with the studs T as shown in Figure 5
and the studs then hold the frame K down on the fillet or flange R.
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 :-
In a liquid meter the improved means of verifying the proper connection of the
registering mechanism or clockwork with the actuating part and the proper working
of such mechanism or clockwork before the casing is put together which consists
in making the joint between the upper and lower part of the casing at such a
point that when the upper part is removed the said registering mechanism or
clockwork and its connection with the actuating part is exposed to view, substantially
as described.
