1, EUGEN BAGGE of Lörrach, Badeu, Germany, Engineer, do hereby declare
the nature of this invention to be as follows:-
My invention relates to an improved construction of fluid meters which I will
describe with reference to the accompanying drawings in which
Figure 1 shews a longitudinal section. Figure 2 a cross section. Figure 3 a
part sectional plan, and Figures 4 to 7 detached details and Figures 8 and 9 shew
details of a modified construction.
The meter is of the cylinder and piston kind, and the improvements have for their
object to prevent as much as possible the deterioration of the parts by impure water,
as also to effect the measurement of the water or other liquid passing through as
accurately as possible.
Between the inlet and outlet branches a and b at bottom and the measuring
apparatus AC at top are two chambers K, and K, the capacity of which
is equal to or greater than the capacity which is displaced by each stroke of
the piston.
The result of this is, that near the measuring cylinder there is always the same
clear water.
With very impure or sandy water, the upper chamber or cylinder A is filled with
oil in order that the water may not come at all in contact with the piston C. In the
position of the piston shewn on the drawing, the chamber A. is entirely filled with
oil; in the chamber K, there is also oil, and in the chamber K, water.
When the slide J is moved from one position into the other, the oil in the
chamber K, is forced by the entering water, through og into A, the piston C is
moved over to the right hand side, oil flows through o into K, and forces the
water out of this through opening o, to the discharge branch b.
The two chambers K, and K, are consequently alternately filled with oil and
water while the measuring chamber or cylinder A is always filled with oil.
The movement of the slide valve J is effected as follows:-
The piston rod carries a bar c which towards the end of the stroke comes in
contact with the stops 1 or 2 on the reversing fod s₁, so as to impart motion
to this.
Between the reversing rod and the slide valve rod s, there is situated a four
armed reversing lever H, pivoted at d. On the axis d is also fixed a lever / which,
together with the spring f, forms a spring tumbler device.
The roller r connected to the rod s₁ presses against the one arm of the lever H
until this is thrown over into the opposite position.
The other arm of H at the same time presses against the roller r, connected to
the slide rod s,, whereby the slide is rapidly noved so as to reverse the position of
the slide. Fig. 4 shews the reversing lever after the reversal of the slide has been
completed.
As shewn at Figs. 8 and 9, levers h, and h, with springs fi and f, can be
arranged on the reversing axis d instead of the lever and spring f of Fig. 7.
The spring is in this case subject to tension and' f, to compression, so that a
couple acts in such manner upon the axis d as to relieve this of strain.
In order that the position in which the reversing lever H tumbles over may be
quite independent, of the frictional condition of the various pivots, the braking
arrangement shewn at Fig. 5 is employed. To the crosshead g of the rod s
are pivotted the two hooks y' and 'y', while the lever H carries the two knife
edges and 8.

page_text: When the lever H begins to tumble over the one knife edge 8' or engages with
one of the hooks y' or y₁, so that only on the farther motion of S' and consequent
motion of H, the said knife edge leaves the said hook, whereupon the lever H can
complete its tumbling movement.
By this means the stroke of the measuring piston C will be accurately limited.
In order that the volume displaced by the stroke of piston C may be accurately
adjusted, the hooks y' y' are provided with regulating screws p' and p³, so that by
adjusting these, the hooks are made to assume a higher or lower position so that the
knife edges and 8 will be liberated sooner or later by the hooks, and
consequently the tumbling over of the lever H and the reversal of the slide valve
will be effected earlier or later.
With small meters, the reversing rods is dispensed with; the piston rod is led
to the outside through a stuffing box and carries the cross-head g with roller r¹.
The cylindrical measuring piston C may conveniently be formed by drawing and
pressing in a similar manner to cartridge cases. In place of this construction,
C might also be made as a fixed open cylinder within A, in which cylinder a solid
piston is made to work to and fro as described.

Improvements in Fluid Meters.
I, EUGEN BAGGE, of Lörrach, Baden, Germany, Engineer, 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:-
My invention relates to an improved construction of fluid meters which I will
describe with reference to the accompanying drawings in which
Figure 1 shews a longitudinal section, Figure 2, a cross section, Figure 3 a part
sectional plan, and Figures 4 to 7 detached details.
The meter is of the cylinder and piston kind, and the improvements have for
their object to prevent as much as possible the deterioration of the parts by impure
water, as also to effect the measurement of the water or other liquid passing
through as accurately as possible.
Between the inlet and outlet branches a and bat bottom and the measuring
apparatus C at top are two chambers K, and K, the capacity of which is equal to
or greater than the capacity which is displaced by each stroke of the piston.
The result of this is, that near the measuring cylinder there is always the same
clear water.
With very impure or sandy water, the upper chamber or cylinder A is filled
with oil in order that the water may not come at all in contact with the piston C.
In the position of the piston shewn on the drawing, the chamber A is entirely
filled with oil; in the chamber K there is also oil, and in the chamber K₁ water.
The supply of water to and from the meter is controlled by two flap valves pi
and p, fixed on the axes 1 and 2. In the position shewn at Figures 1 and 3 the
water has, been entering in the direction of the arrow II into the chamber K₁ and
has been passing in the direction of arrow IV out of K. When P1 and
reversed, the water enters the chamber K, in the direction of arrow I and flows off
from K₁ in the direction of arrow III.
Ps are
The gearing for actuating the flap valves is shewn in side view at Figures 1, 4, 5,
and 6, and in plan at Figure 7.
The reversals of the flaps pl p' are effected by causing the toothed rack Z' fixed
on the piston-rod p to rotate the pinion Z fixed on the axis 3 (Figures 1 and 7),
the arm a', Figure 7 fixed on the axis 3 being made to reverse the position of the
tumbling weight F at the end of each stroke of the piston.
I.

page_text: The weight F falls on to the one or other of the caoutchouc buffers 63, fixed on
the arm a³, whereby, by means of the arm a² and the rod b', the armis a' and a fixed
on the axes 1 and 2, and consequently the flap valves p' p³, also have their position
reversed.
For effecting the registration of the quantity of water passing through the
meter, the piston rod's motion is continuously registered.
To the cross head fixed on the piston rod p is pivotted the rod which moves
the rocking lever backwards and forwards; the axis of this lever carries a toothed
quadrant Z gearing with a pinion Z on an axis 4, so that the latter receives by the
above means a reciprocating rotary motion.
By means of the right and left handed ratchet gear Z' Z, Figure 7, and the
bevil wheels Z' Z Z the axis 5 will be continuously rotated in one and the same
direction, so that the pointer f¹ which represents the counter mechanism, will
indicate, continuously upon a graduated dial the strokes of the piston. For
accurately regulating the indications of the counter so as to represent correctly the
quantity of water passed through the meter, the rocking lever Figure 5 is provided
with a screw spindle G' carrying a nut to which the rod is pivotted, so that by
adjusting the position of the nut by means of the screw spindle the throw of the
lever will be made larger or smaller, so that the motion of the pointer will be
made correspondingly larger or smaller for each stroke of the piston.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A fluid meter wherein two chambers, K' and K' are arranged between the
upper measuring cylinder C and the lower valves p' p³, the capacity of which
chambers is equal to or larger than that displaced by each stroke of the piston, for
the purpose of preserving the working parts of the meter from contact with impure
water, substantially as described.
2. In a fluid meter constructed and operating as set forth in the first claim,
maintaining the measuring cylinder A full of oil in order to prevent impurities from
gaining access thereto, substantially as described.
