do hereby declare the nature of my invention for IMPROVEMENTS IN WATER MOTOR
GOVERNORS to be as follows:-
.
This Invention relates to Improvements in Water Motor Governors. Some
portions of which are also applicable to the governors for which letters patent were
granted to the present applicant A.D. 1879, 24th Decr N° 5274. The improved
governor consists (in the way I prefer to make it) of a pair of cone pullies,
connected by a belt which is moved accross their faces by a guide or guides in
connection with the governor balls. On the end of the spindles carrying the cone
pullies 1 wheels; by preference (bevil) are attached, which work with others
forming what is commonly known as the jack in the box motion so that as long
as the strap guide keeps the belt in such a position on the cones that the 2 wheels
which gear into the jack wheel running at the same rate the spindle on which the
jack wheel runs will remain stationary and no movement of the sluice gate will
take place. Should however the balls move either way from their normal position
a variable speed will be introduced, and the jack spindle will move in either one
direction or the other, opening or closing the shut till the proper speed is again
restored Instead of 2 cone pullies one cone pulley and a parallel pulley may be
used with a straining pulley kept up by gravity or a spring to take up the slack:
or expanding pullies or pulley may be used. Also instead of the bevil wheels spur
wheels may be used. To avoid the shut running back which heavy working shuta.
are liable to do, I use a locking gear which locks both ways, but automatically
unlocks itself as soon as the power is applied in either direction. It consists of a
fixed ratchet wheel with pawls dropping into it in opposite directions and these
pawls are lifted out by a cam which moves first far enough to do this, after which'.
it becomes the driver. This locking gear may be applied to a variety of other
purposes. The strap guide instead of being actuated by the governor balls, may be
connected with a float, in which case the shut will be controlled by the level of the
water as described in patent N° 5274-1879.
In most cases it is essential that the governor should throw itself out of gear
when the shut gets wide open and in many cases when it gets wide open & when
it gets wholly or partially closed.
In cases where it is only essential to throw the governor out when the shut gets
wide open I prefer to use a nut on a screw which comes against a stop which turns

page_text: with the screw and thus compels the stop & nut to turn together, when an arm or
its equivalent on the nut throws the governor out of gear. When it is desireable to
throw the governor out both ways, I use a crown wheel which gears into a scroll,
making its mation relative to the shut just before the shut gets to any positions it
is wished to throw the governor out at projecting plates which are fastened in their 5
right positions for doing so come into contact with a pendulus cam; which turns it
up in either direction, and thus thows the strap or the pawls into a neutral
position. A bell may be connected with this cam or other part of the governor
which will cause it to ring as soon as the governor throws itself out.
These throwing out arrangements are equally applicable to the speed & float 1
governors described in patent N° 5274-1879.
Improvements in Water Motor Governors.
I, HENRY JAMES HOGG KING of Newmarket near Stroud, Gloucestershire
Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
WATER MOTOR GOVERNORS and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
This Invention relates to Improvements in Water Motor Governors some portions
of which are equally applicable to the governors for which letters patent were,
granted to the present applicant A.D. 1879 24 Decr N° 5274 and in order that my
said Invention may be properly understood, I have annexed hereunto a sheet of
explanatory drawings.
Figs 1-2 & 3 show different views of the improved governor. The governor
balls 1 may be driven in any convenient way from the motor by a belt on the
pulley 2 & through the medium of the wheels 3-4 & 5 The shaft 6 is the one
connected with the shut or gate of the water motor and it is essential that this
shall move in either direction to put on or take off water as the circumstances may
require To effect this object I use what is commonly known as the jack in the
box motion in which 7 is the jack wheel; the axle 8 on which it turns being
rigidly fastened to the shaft 6 by means of the key 9-It will now readily be.
understood, that if the wheels 10 & 11 move in opposite directions at equal speed
and both have the same number of teeth, no movement of the axle 8 or shaft 6
will take place, but if the wheel 11 moves faster or slower than 10 a differential
movement will result & the shaft 6 will be turned correspondingly. If the speed
of the 2 wheels 10 & 11 vary but slightly, the movement of 6 will be slow, if
they vary considerably the motion of the shaft 6 will be rapid-To produce this,

page_text: differential movement I employ the cone pullies 12 & 13 which are connected with
the belt 14 When the belt runs in the centre of the pullies as shown they both.
run at equal speed and the wheels 10 & 11 will do the same but if the belt 14 is:
shifted by the governor balls, either way from the central position, the cone.
pulley 12 will run faster or slower than 13 and the wheels 10 & 11 will participate.
in these variations, and cause the shaft 6 to move with a variable velocity in the.
direction required.
The belt 14 is shifted across the cone pullies by means of the strap guides 15
& 16 by the governor as it rises and falls.
Instead of the 2 cone pullies 12 & 13 one of them may be parallel and the other
coned & the slack of the belt may be taken up by means of a tightening pulley
kept up to its work by gravity or by a spring; or expanding pullies may be used
or friction pullies in short any known mechanical arrangement which gives a
variable speed.
Instead of the governor balls the belt 14 or its equivalent may be moved across
the pullies or be controlled by the float of the float governor described in the
previous patent.
In heavy shuts or gates which are worked by gearing other than a screw &
(worm wheel which is usually too slow a motion to govern with) there is a great
tendency for the wheels to fly back and undo the work which has been previously
done by the governor.
To prevent this I use the locking arrangement shown in Figs. 4 & 5. In this
case it is assumed that the governor shaft 6 is connected to the shut by means of
the chain 18 and chain wheel 19-The 2 studs 20 & 21 are rivetted into the chain
wheel 19 which is loose on the shaft 6, but can not turn round, being fastened by
the arm 26 to something which is rigid The driving arm 27 is keyed to the
shaft 6 and if we assume it moves in the direction of the
it lifts the
pawl 23 clear of the wheel 25, and coming against the snug 28 cast on the chain
wheel 19 turns it round in the direction of the →. Should however the motion
of 27 be reversed, the wheel 19 can not fly back as it is held by the pawl 22 in the
wheel 25, & the wheel 19 can not move in the opposite way, till the arm 27
lifts the pawl 22 out of gear This locking gear is applicable to all water motor,
governors.
In water motor governors it is essential when the shut or gate gets wide open
that the governor should throw itself out of gear and it is also necessary in some
cases that it should throw itself out of gear at different stages of the closing of
the gate To effect these purposes I employ 2 arrangements according to circum-
stances. One is shown in Figs. 6-7 & 8 and the other in Figs. 2-9 & 10-These
arrangements are also applicable to the governors patented (specification 5274—
1879).
N° 28 & 29 in Figs 6-7 & 8, are the pawls which work round the ratchet
wheel 30 which wheel is in direct communication with the shut.
On the face of this wheel, there is a scroll cast 31, into which the crown
wheel 32 gears at its lowest side, it being pitched as shown to keep the scroll clear
at the top-On the face of the wheel 32 a plate or plates 33 is or are screwed and
it is shown in Fig. 8 just begining to turn the cam 34 round.
This cam turns easily on the shaft 35 and the weighted side 34' always falls to
the bottom when it is free to do so, and in this position both the pawls 28 & 29
are unaffected by it-We will assume that the shut is nearly wide open and that
the pawl 28 is opening it.
It is thus necessary to throw this pawl out of action & this is done by setting
the wheel 32 so that the plate 33, comes into contact with 34 as shown in Fig. 8
It will then turn it round in the direction of the and bring the raised part
of the mask or cam 36 under the end of the pawl 28, and prevent it falling into
the teeth of the ratchet wheel as shown in Fig. 6. If it is necessary to throw
the other pawl 29 out of gear, the opposite end of the plate 33 or another plate
screwed on the crown wheel 32' will do it.

page_text: The other throwing out. arrangement shown in Figs. 2-9-& 10 consists of a
screw 39 which is driven by gearing from the main shaft 6. 40 is a casting with
a thread in it which fits the screw and. is usually kept from turning round with
the screw by the weighted end 40¹. As the screw turns round, it will move slowly
along, till it comes into contact with the collar 41 which is fixed to the screw, it
then jambs against the face of 41 and is carried round with the screw till the
arm 40¹ comes under the lever 42 and lifts the governor into its central position
with the result that its action in moving the shut in either direction is arrested.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
1 The application of the bevil wheel arrangement, commonly known as "the
jack in the box" for the purpose of producing a variable forward & backward
motion in Water Motor Governors, which motion is applied to the opening or
closing of the shuts or gates of Water Motors.
2nd The application of the locking gear as shown in Figs 4 & 5 to Water Motor
Governors.
3rd The application of the throwing out gear, substantially as described in
Figs 6-7 & 8 to Water Motor Governors..
4th The application of the throwing out gear, substantially as described. in
Fig 9 & 10 to Water Motor Governors.
