PROVISIONAL SPECIFICATION.
Improved Water-wheel Governor.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Thomas Coulter, Inventor, and Morris Pereles,
Gentleman, both of Dayton, Ohio, U.S.A.) to be as follows:-
This invention relates to an improved governor or speed regulator for water-
wheels.
The construction of this invention is mounted upon a suitable base-plate. A
shaft is horizontally journalled upon this plate, and carries at one end the drive-
pulley. A sleeve having several arms projecting outwardly therefrom, is mounted
centrally between its bearings, and which arms carry at their ends suitable
disengaging dogs, which operate upon suitable pawls which engage the teeth of
two ratchet wheels mounted upon the shaft at opposite ends of the sleeve
aforesaid. Two mitre-wheels are loosely mounted upon the shaft, adjacent to
the ratchet wheels, and engage the teeth of a smaller mitre-wheel mounted upon
the end of a second shaft journalled in bearings at right angles to the shaft
first-named, and which shaft carries a worm. This worm engages a worm-wheel
mounted upon a third shaft, arranged in bearings parallel to the first-named
shaft, and at right angles to the second-named shaft. The third-named shaft
carries at one end a wheel having projecting teeth in its face, and a band
passing over its periphery, and which band communicates motion to a pulley
upon the first-named shaft. A weighted rod is adapted to come into contact
with the projecting pins upon the face of the wheel upon the third-named
shaft, and which weighted rod operates the disengaging dogs aforesaid, and
thereby throws the pawls out and into the ratchet wheels as the speed varies
the motion of the weighted lever aforesaid.

Improved Water-wheel Governor.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Thomas Coulter, Inventor, and Morris Pereles,
Gentleman, both of Dayton, Ohio, U.S.A.) 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 improvements in water-wheel governors, which will be
fully hereinafter described and claimed. The object of my invention is to regulate
the flow of water to a turbine or other form of water-wheel by a compact mechanism
which will be sensitive, yet sufficiently powerful to operate any gate. The
mechanism is illustrated in the accompanying drawings, in which-
Figure 1 is a top view of the governor with portions omitted.
Fig. 2 is a view of the left side of the same with parts to the rear omitted.
Figs. 3 and 4 are enlarged detail views of some of the parts.
Fig. 5 is au enlarged detail end view of the driving-arm.
Fig. 6 is a front detail view of the shifting device.
Like letters and numerals designate like parts throughout the several views.

page_text: A is the base, which, with the several standards supporting the shafts, forms the
frame of the machine. To the shaft I at the right end is attached the driving
pulley H, in the centre is the driving-arm 1, and on the left end the pulley K.
External to the driving-arm are the mitre-wheels B and C, and to the sides of
which are attached the ratchet-wheels B¹ C¹. The mitre-wheels are loose on the
shaft, and the other parts are rigidly attached. The mitre-wheel D, supported
on a shaft at a right angle to the former, is continuously in gear with the two
former. The screw-wheel F on the latter shaft engages the worm G on the shaft E,
and this shaft is connected in practical use with the gate of a water-wheel. The
ends of the driving-arms 1 carry a series of dogs and pawls. The several parts of
the two ends are identical, and one set would suffice; but the two parts combined
give a more immediate motion to the gate-rod.
The relation of the several parts could not be clearly shown in Fig. 1, and are
therefore more fully illustrated in Figs. 3, 4, 5 and 6.
At Fig. 3 is shown the left ratchet-wheel B', and the mitre-wheel to which
it is attached is only shown in outline by the external circular dotted line.
The inner line shows the circuit of the end of the dogs, and the arrow in this
line indicates the direction of the motion. Two pivots support the dogs and
pawls in the arm projections. The pawls 2 on the outside of the arm projec-
tions are rigidly attached to the pivots. Adapted to engage with these pawls
are flat springs 3, which bear on pins in the sides of the pawls, and are
secured to the arm-projections. These serve to hold the pawls in position when
either in or out of the ratchet-wheels, and notches may be used in the springs
to more effectually hold the pawls in proper position. A. compound dog com-
prises parts 7, rigidly attached to the aforesaid pivot-pins which have segmental
cogs on their under surface that engage a like series of cogs on the parts 6,
which have projections to engage the throwing-arm 18. The upper part of
each is held on a pin in an extension 5 of the driving-arm. When the under
part of this compound dog strikes the throwing or shifting-arm 18 the pawl 2
is made to engage the ratchet-wheel B' and the mitre wheel B is made to
rotate. The shifting-arm is held on the square bar 16, which is held in a
frame 17, attached to the base, and within the slots of which the same freely moves
laterally. When the shifting-arm 18 so moves as to engage the dog 19, the pawl
is thrown out of the ratchet-wheel and the mitre-wheel ceases to rotate, and when
the dog 20 is struck the same effect results. The rod 10 connects the two opposite
disengaging-dogs, and they therefore move simultaneously as one or the other is
struck. The relation of these parts is shown at Fig. 4, and the relation of the
compound engaging-dogs and pawls to the driving-arm, ratchet-wheel, and mitre-
wheels is shown at Fig. 3. The pulley K is connected by the belt L with the
pulley J, which has four pins s near its periphery and equidistant apart. This
pulley is supported on a spindle held in an arm of the frame. To the standard N
is pivoted the arm or lever M. At the end, to engage the pins, is fastened the
metallic plate t, which as it springs relieves the jar consequent upon the pins
striking the same as the pulley J revolves.
O is a weight used to keep the outer end of the lever down against the pins and
overcome the weight and friction of the connecting parts. The arm 26 is attached
at its inner end to the standard, and to its outer end is pivoted by bolt 21 the
rod 14, which at its lower end is connected to the bar 15, which is joined to the
shifting-arm 18. The arms 12 and 13 are connected to the rod 14 near the top
and about equidistant from its pivot. The pulley J and the weight cause the
lever M to oscillate, engaging usually alternately said arms 12 and 13. This
produces a reciprocating movement of the shifting-arm 18. The operation is thus:
The shaft E is connected by mitre-gear or otherwise to the gate-rod of a water-
wheel. Motion is given by a belt from the main shaft over the pulley H, and the
driving-arm is made to rotate. When the lever M is in its normal position the
dog 18 is in position to be struck by the compound dog 6 and 7. This throws in
the pawl 2 and causes the mitre-wheel B to rotate, and this, by means of the worm-

page_text: gear rotates the shaft E to open the water-wheel gate. When, however, each pin s
comes into contact with the part t of the lever M its forward end is brought into
contact with the arm 13, which causes the rod 14 to oscillate on its pivot 21 and
reciprocate the bar 16 which slowly and continually brings the dog 18 into contact
with the dog 19, and the movement in opening the gate would be discontinued, on
account of the dog which is fixed to its pivot,-turning the pivot and throwing the
pawls 2 out of engagement, and if the speed became too great the shifting-arm
would be thrown (in consequence of the sharp and rapid impact of the part of the
lever M on the pins s) so as to engage the compound dog to the right. This
would give motion to the mitre-wheel C, and as a consequence the action of the
gate would be reversed. It will be understood that the weight O tends to keep
the lever M in its normal position. The effect of the pulley J with its pins and
the weighted lever M is to keep the shifting-arm in rapid vibration, and as this
reverses the motion, depending on the speed of the main shaft, the motion is thereby
regulated. The two disengaging dogs are intermediate to the engaging-dogs, and
consequently one pawl is disengaged before the other is engaged. The same device
may be used in regulating the motion of a steam engine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. In a speed regulator, the combination of the pulley H, driving-arm 1, provided
with the compound dogs of parts 6 and 7 and pawls 22, held on separate pivots,
the disengaging dogs 19 and 20, loose mitre-wheels B and C, ratchet wheels B₁ C',
attached thereto, mitre-wheel D, worm gear of parts G and F, the latter on shaft E,
pulleys KJ, the latter having engaging-pins S and the two pulleys being connected
by the belt L, weighted lever M to engage said pins, rod 14, with engaging-
arms 12 and 13, connective bar 15, and the reciprocating shifting-arm 18 to throw
said pawls out and into the ratchet-wheels as the speed varies the motion of the said
weighted lever, substantially as shown and described.
2. The mechanism for reversing motion, the pulley H, driving-arm 1, provided
with the compound dogs of parts 6 and 7 and pawls 2, 2, held on separate pivots,
the disengaging-dogs 19 and 20, loose mitre-wheels B C, ratchet wheels attached
thereto, and mitre-wheel D, held continuously in gear with the former mitre-wheels,
these several parts being in combination, substantially as set forth.
