ADOLPHE PRUNIER, SON, of Livron, in the Department of the Drôme, in the
Republic of France, Mechanic. "A NEW OR IMPROVED WATER-REGULATOR."
My improved water-regulator is composed of three distinct parts, which may be
placed at variable distances according to the requirements of the position or
locality.
The first part is compossed of a ball-regulator or centrifugal force governor, shewn
in section, side view, and elevation in the three Figures A, B, C, Sheet 1 of the
accompanying 4 Sheets of Drawings.
The parts Nos. 1, 2, 3, 4, 5, and 6, shown separately, belong to the first part.
The rising or lowering of the piece No. 1 (which movement results from an increase
or decrease of speed) is transmitted by the aid of the pieces a, b, c, to the second
part by the draw-wire or cord d, e
The second part is composed of a return piece, shown in elevation and side view,
Figs. D, E, Sheet 2.
The piece No. 7, shown separately, belongs to the second part.
The draw-wire d, e, having attacked the return piece at the point c, takes again
at the point fand goes thence to the third part, which it attacks at the point g.
The third part is an apparatus acting directly on the valve or batch, and is shown
in side view, elevation, and plan in the Figs. F, G, H, Sheets II., III., IV. of the
Drawings.
The pieces 8, 9, 10, and 11, shown separately, belong to this third part, which
apparatus may itself be divided into three distinct parts, which are, 1°, the oscillating
frame; 2°, the valve or hatch; 3°, the shaft of the connecting rods.
First. The oscillating frame is of rectangular form and carries,-
1°. Two shafts placed length-wise, upon each of which is placed a bevil pinion, a
ratchet wheel, and a balance-lever; this latter carries at one of its ends a pawl,
which according to its shape and arrangement is out of gear each time that it is at
rest.
2°. A shaft crosses the frame length-wise, and also carries a bevel pinion gearing
with the two others. This shaft supports the frame, and is screw-threaded to a
variable extent in its extension towards the valve or hatch; a nut fits on to this
screw-threaded part and itself receives a cap with socket (piece No. 10), into which
fits a rod leading directly to the lever arm acting on the valve.

page_text: 3°. A circular rod p carries a small piece q provided with an adjusting screw, and a
hook carrying the weight which constantly counter-balances the pieces a, b.
4°. The two pieces n, o, fixed by a bolt and regulating the oscillation of the
frame.
Second. The valve or hatch, varying according to the requirements of the position,
is composed of a sheet of iron set in a frame; it carries at its lower part four
grooved or recessed friction-rollers i, i, i, i, the bearings of which are on the two iron
rods j, k. This arrangement permits the valve or hatch to bear very considerable
pressures of water without therefore greatly increasing the power to be reproduced
by the apparatus for its working; it further carries two other grooved or recessed
rollers, m, placed on each side at an equal distance from the axis of the valve;
the two lever arms (piece No. 8) which give the up and down movement of the
valve or hatch are connected to these rollers.
Third. The shaft of the connecting-rods carries at its ends two excentrics, to each
of which is connected a rod passing exactly under the balance beams of the frame.
Motion is given to the connecting rods by two wheels with crossed paddles. In
hydraulic wheels with a race these two wheels cannot be adopted, and are replaced
by a pulley receiving motion from the motor by means of a band or by other
device.
