"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR REGULATING WATER
WHEELS."
The object of my Invention is to regulate water wheels in such a manner that
the varying weight of machinery the water wheel is turning will be kept at one
constant and uniform speed.
I accomplish my object in the following manner:-On to the main driving shaft,
or what is commonly known as the second motion shaft from the water wheel, I
secure a brake pulley of proportionate diameter and width corresponding to the
Around this said brake
diameter and power of the water wheel to be regulated.
pulloy, or partly around the same, as the case may be, I place a brake strap; one
end of the said strap I attach to a stud and bracket, which is secured to any con-
venient portion of the building; the other end of the said brake strap I attach to
a sliding socket on the top of a pair of ordinary governors, which I use in com-
bination with the brako pulley and strap. To attain my object the top part of the
long arms or pendulums of the said governors are extended beyond the studs or
point of suspension. At the extremo ends of the extended arms or pendulums I
attach two short arms, which project towards the centro spindles of the governors
and are coupled to the aforesaid sliding socket placed at or near the top of the
governor spindle, to this said sliding socket I secure one end of the aforesaid brake
strap.
It will be readily understood that when the water wheel is revolving too fast, in
consequence of the varying amount of machinery in motion, the governors will
also revolve faster in the same proportion, when the governor balls will rise
and the extended ends of the long arms will draw the sliding socket down or
away from the second motion sbaft and brake pulley and tighten the brake
strap on the brake pulley, by which means the power will be kept more

the same is to be performed, I wish it to be understood that I do not limit myself
to the precise details herein described, as the same may be varied without departing

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the

GEORGE LISTER, of Keighley, in the County of York, Manufacturer. "IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR REGULATING WATER WHEELS."
The object of my Invention is to regulate water wheels in such a manner that
the varying weight of machinery the water wheel is turning will be kept at one
constant and uniform speed.
I accomplish my object in the following manner :-On to the main driving shaft,
or what is commonly known as the second motion shaft from the water wheel, I
secure a brake pulley of proportionate diameter and width corresponding to the
diameter and power of the water wheel to be regulated. Around this said brake
pulley, or partly around the same, as tho case may be, I place a brake strap; one
end of the said strap I attach to a stud and bracket, which is secured to any
convenient portion of the building; the other end of the said brake strap I attach
to a sliding socket on the top of a pair of ordinary governors, which I use in
combination with the brake pulley and strap. To attain my object, the top part of
the long arms or pendulums of the said governors are extended beyond the stud or
point of suspension. At the extreme ends of the extended arms or pendulums I
attach two short arms, which are coupled to the aforesaid sliding socket placed at
or near the top of the governor spindle, to this said sliding socket I secure one
end of the aforesaid brake strap by means of an universal ball joint and buckle.
It will be readily understood that when the water wheel is revolving too fast,
in consequence of the varying amount of power required to drive the machinery,
the governors will also revolve faster in the same proportion, when the governor
balls will rise and the extended ends of the long arms will draw the sliding socket
down or away from the second motion shaft and brake pulley, by which means
the brake strap will clip the brake pulley tight, thus the power will be kept more
constant and regular.
Having now described the nature of my Invention, and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself to
the precise details herein described, as the same may be varied without departing
from the nature of my Invention; but I claim as my Invention a new and improved
apparatus for regulating the speed of water wheels driving machinery, the parts
of which are arranged and worked in combination with each other essentially in
the manner herein-before described.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation of my improved apparatus; Fig. 2 is an end elevation of
the same.
The water wheel, gearing, and other parts that are not necessary for
the elucidation of those improvements are omitted in the Drawings, being the same
in any ordinary water wheel to which my improvements may be applied.
The governor spindle is indicated by the letter A, which is mounted on an
ordinary footstep not shewn on Drawings, and driven by means of a strap or
gearing, as the case may be, through the spindle A. At B is a slot hole passing
through the spindle, in which are suspended the arms or pendulums C, C, on stud
D. The balls E are secured to one end of the arms C, these arms work freely in

page_text: guards F, F. The arms C, C, are extended beyond the joint of suspension D, to
which are attached two arms or links G, G, coupled to sliding socket H. At the
top of H, secured thereto, is an universal ball joint J. On the shaft K is mounted
the brake pulley L, around which is brake strap M, one end of which is secured to
5 a bracket N, the other end of the strap M. is attached to the universal joint J by
means of rod O and bracket P. It will be readily perceived that when the governors
are revolving at a greater speed than calculated to give the required speed to the
machinery the balls by the centrefugal forco will expand outwards from the centre
of the spindle and draw the sliding socket H down towards the suspending stud
0 D, and thus tighten the brake strap M on the pulley L and brake, or impede the
motion of the water wheel, causing it to revolve at the proper speed.
In witness whereof, I, the said George Lister, have hereunto set my hand and
seal, this Sixth day of November, in the year of our Lord One thousand
eight hundred and seventy-six.
