IMPROVEMENT IN WATER-WHEEI: REGLATORS.

The Schedule referred to :in these Letters Patent and making part of the same.

To all whom it may concernI e) Beit known that-we, J uns P. Sinner and An- THUR NVALSH, of Bennington, in the county of Bennington and' State of Vermont, have invented a new and useful Improvement in Regulators and we do' hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to lmake and use the same, reference being had to the accompanying drawings forming part of this specitication.

'The object of vthis invention is to provide a regulator for water-wheel gates, which may also be applied to steam-engines or other machines, for regulating the speed of machinery, and consists in the construction, arrangement, and combination of parts, as hereinafter more fully described.

In the accompanying drawing- Figure 1 represents a sectional elevation of the regulator.

.Figure 2 is a horizontal section of Iig. 1, through the line :t fr. Y

Figure 3 is a view of the stop-plate which operates upon the pawls, (detached,) or to detach the pawls.

Similar letters of reference indicate corresponding parts.

A is the'bed-plate, upon which the frame and operating parts of the regulator are supported. B is the frame. s

C is the head of a centrifugal governors.

D D represent the balls ofthe governor.

E is the governor-spiulle, which is supported in an upright position by the frame B.

F is a pulley, by which the governor is rotated by means ofthe gear-wheels Grand H.

I is a frame, sliding on -thebed, and receiving its motion from the eccentric J on the governor spindle by means ot' the rod K, or by a str ap.

rlthis frame is provided with four pawls-L L, which are made to engage with the. ratchet-wheel M by the reciprocating motion oi' the frame l. f

The pawls L L turn the ratchet-wheel in one direct-ion, and the-pawls L L turn it in the opposite direction. These pawls are allowed to engage with the wheel only when there is avariation in the speed ofthe governor.

N yis a shield on the shaft or spindle i). (The ratchet-wheel M is attached vto this shaft O.) Theshield N reaches out to the circumference of the ratchet-wheel, and has guard-plates P which drop down directly over the cog`s or teeth ot' the wheel, so

as -to preventthe pawls from engaging with the wheel, except when opening or when closing the gate for increasing `or diminishing the power. 'lhe posit-ion of this shield and the plates 1 is controlled by the action ofthe governor.

The motion is imparted from the grooved thimble E by the forked bell-crank S, which oscillates on the shaft T, and the rod U, which is attached to the top oi' the shield so as to give the shield 'a rotating or circular motion on the shaftO, and thus change the position of the plates P.

The pawls are kept in constant contact with the plates, when not engaging with the teeth of the wheel, by the small springs V, which are attached to the studs W.

X is the stop, which consists of' a bar, through which the upper portion of the shaft O works by means ot' a screw-thread, so that the bar X acts as aunt, and is carried np and down as the shaft is turned.

As the ratchet-wheel is turned, the stop-bar will be brought down against the shoulder onthe screwshaft O. When the stop is in this position the gate or valve is fully open, and it will then turn with the ratchet-wheel, its motiolr being limited by the stud X.

The -pin y in the stop-bar X will come in contact with the pin s in the shield, and hold' the shield and guard-plates P in suclrposition as4 to prevent the. pawls from engaging with the ratchetfwheel. At the same time the 'regulator will be left i'reeto close the gate.

or valve when the speed is increased above the required velocity.

c (fig, 3) is a plate, which is made to turn on the shaft- O, and is allowed to operate directly on the points of'two or oi' all the pawls L' L', so as to disengage them from the ratchet-wheel when it is necessary to close the gate.

da' are recesses in the rim of this'plate, which allowthe p twls to engage with the Wheel at other times.

This plate is operated or adjusted by means of the rod b'. s

It will be seen that the regulator may be made single-acting by detaching two ofthe pawls.4

We donot confine ourselves to any particular position in which to place theoperating parts ofthe regulator. Instead oi' placing the ratchetfwheel in a horiontal position, as represented, wemay place it in a vertical position, or on a horizontal shaft, with the parts connected therewith in correspondingpositions.

Having thus described our invention,

. We claim as new and desire to secure by Letters Patent- 1. '.Lhe ratchet-wheel M, in combination with the sliding frame I and pawls L L arranged to operate substantially as and ior the purpose herein shown and described.

2. The plate s', iu combination with the pawls, substantiall y as and for the purpose specified.

3. The stop' X, in combination withI the shaft O and ratchet-wheel M, substantially as and for the purpose specified.
