I JOSEPH GRIFFITHS, Tool Maker, Caergwrle Nr Wrexham, do hereby declare the
nature of my invention for IMPROVED METHOD OF REGULATING THE SPEED OF
MACHINERY to be as follows :-
My Invention relates to a novel mode of Regulating the Speed of Machinery by
means of Governors and Tapered Cones. At Fig. 1, I show a pair of Governors
driven by Gearing from shaft I, whose speed is to be regulated.
On slide box B I show two bevel wheels K and N, C is another bevel wheel, fixed
on the Spindle of a Worm which works worm wheel D.
On the Spindle of wheel D is a pinion P Fig. 2 which works the Rack E. This
Rack carries either a Fork or two arms, or projections between which the belt G
works on the Tapered Cones.
His the driving Shaft and I a Counter Shaft, any increase in the speed of Shaft I
will cause the Governors to rise bringing the Bevel wheel K into contact with
wheel C, causing it to revolve, and the Fork F moves forward altering the position of
the belt on the Cones, and the Speed of Shaft I will consequently he decreased, when
the Governors will lower themselves, from Contact with wheel C.
Any decrease in the speed of Shaft I will cause the Governors to descend and bring
wheel N into contact with wheel C setting it in-motion and causing the Fork F to move
backward and to change the position of the belt on the cones until the shaft I regains
its normal speed, when the Governors will rise free from contact with C, any change
in the Speed of the Machinery is at once checked by the Governors changing the
position of the belt on the cones and causing Shaft I to run at one uniform Speed.
Where sudden and extreme changes are likely to occur such as with Windmills, I put
a Flywheel or wheels on Shaft I.
The Wheels C. K. and N may be either Cog wheels, Friction wheels, or smooth
wheels, and may be made of any material, such as Iron, Steel, Wood, Gutta Percha,
India Rubber, &c, or any material which will suffice by Friction to work the Worm
and Worm wheel, and the Wheels may be of any pattern either like those in Fig. 1,
or those in Fig. 3 or any modification of those patterns.
The fork Finay be worked by a lever on the Spindle of wheel D instead of a pinion
or by a belt, or by chain working over a pulley.
The Governors may also be made to act direct on the belt or the cones by means of
levers as shown in my application for Improved Windmill, dated March 27th 1886,
I therefore claim as new, this Method of Regulating Machinery, by means of
Governors and Tapered Cones.

page_text: I, JOSEPH GRIFFITHS Toolmaker Caergwrle near Wrexham do hereby declare
the nature of my invention for IMPROVED METHOD OF REGULATING THE SPEED OF
MACHINERY 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 a novel mode of regulating the Speed of Machinery by
means of Governors and Tapered Cones. This description will be better understood,
by reference to Drawings accompanying Provisional Specifications. At Fig. 1 I show
a pair of Governors driven by gearing from Shaft I, whose speed is to be regulated.
On slide-box B I show two bevel-wheels, K and N. C is another bevel wheel, fixed
on the spindle of a worm, which works worm-wheel D. On the spindle of wheel Dis
a pinion P Fig. 2 which works the rack E. This rack carries either a fork or two
arms or projections, I between or through which the belt G works on the tapered
cones.
His a driving shaft and I a counter-shaft. Any increase in the speed of shaft I
will cause the governors to rise, bringing the bevel wheel K into contact with wheel C,
causing it to revolve, and the fork F moves forward, altering the position of the belt
on the cones, and the speed of shaft I will consequently be decreased, and the
governors will lower themselves from contact with wheel C. Any decrease in the
speed of shaft I, will cause the governors to descend, and bring wheel N into contact
with wheel C, setting it in motion, and causing the fork F to move backward, and to
change the position of the belt on the cones, when the shaft. I will regain its normal
speed, and the governors will rise free from contact with wheel C.
Any change in the speed of the machinery is at once checked, by the governors
changing the position of the belt on the cones, thus causing shaft I to run at one
uniform speed. Where sudden and extreme changes are likely to occur, such as with
windmills, I put a fly-wheel or wheels on shaft I.
The wheels C, K and N may be either cog-wheels, friction wheels, or smootli wheels,
and may be made of any material such as iron, steel, wood, gutta percha, India
rubber, &c. or any material which will suffice by friction to work the worm and worm
wheel, and the wheels may be of any pattern either like those in Fig. 1, or those in
Fig. 3, or any modification of those patterns.
The fork F may be worked by a lever on the spindle of wheel D, instead of a
pinion, or by a belt or a chain working over a pulley. The governors may also be
imade to act direct by means of a lever or levers on the belt on the cones.
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,
The method of regulating the speed of machinery by means of Governors and
Tapered Cones.
