Improvements in Turbine Governors.
I, CHARLES LOUIS HELT, of Ancholme Iron Works, Brigg, in the County of
Lincoln, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of my invention is to produce a powerfull turbine governor, which will
adjust any fluctuation in the speed of the turbine, at a rate varying with the magni-
tude, that is, that a slight variation of speed will be followed by a slow action of the
governor, while a greater fluctuation will lead to greater action of the governor.
My invention consists essentially of a centrifugal or ball governor, which may be
of any convenient type, and of a pair taper cone pullies, with belt and gear by which
the rise or fall of the governor, moves the belt along the cones, causing the driver
cone to revolve faster at the same speed, or slower than the driver, according to the
position of the governor, and therefore to the speed of turbine, and to reduce this
different speed to a revolving speed, an! in both directions, I employ the arrangement
known as the "jack in the box" in roving frames, and so compensated or differential
gear in tricyles and traction engines.
The governor is driven by a belt on the driving pulley C. When the governor
revolves at its mein speed the upper taper cone E, drives the lower taper cone F,
then to belt K, at the same speed as that at which it revolves.
The movement of the upper cone is transmitted through bevel wheels, and the
governor spindle to the upper pinion of the jack in the box S, while the motion of
the lower cone is communicated through similar bevel gear to the lower pinion T, the
upper to lower "jack in the box" pinion now revolve at the same speed, and in
opposite directions and the inside pinions U, U, simply revolve on their axles without
carrying them round the governor spindle.
If the speed increases, the governor expands, moving the belt K, to the large end
of the upper cone E, and small end of the lower cone F
The lower cone, and consequently the lower jack pinion T, will now be driven
faster than the upper one, and the axles of the middle pinions will be carried round
the governor spindle taking with them the jack wheel V, which in its turn drives the
spurwheel on the handle wheel spindle, W.

page_text: With a slower speed the governors falls and the reverse action takes place. The
spurwheel W, is loose on the hand wheel spindle, and drives it by means of a
clutch L, and catch P, which will slip, when the gates are full open, and which can
be thrown out of gear by means of plate O, for stopping.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon."
Figure 1, represents a vertical section of the governor. Figure 2, is the side
view of the revolving pendulums. Figure 3. represents the side view. Figure 5, the
bed of the framework.
Like letters refer to like parts in each of the figures. A, the pendulumns. B, governor
spindle. C, driving wheel. D, joint rods. E, upper taper cone. F, lower taper cone.
G, and I, bevel gear driving governor spindles. H, and J, bevel gear driving lower
pinion of "jack in box." K, belt. L, clutch. M, hand wheel. N, hand wheel spindle.
O, clutch for disengaging. P, catch. Q, bed of frame work. R frame. S, upper
pinion of jack in box. T, lower pinion of jack in box. U, U, middle pinions of jack
in box. V, jack wheel. W, spur wheel on handle shaft.
Having now fully described the nature and object of my invention and the manner
in which the same is to be performed, I claim as new and novel the following
First. The combination of a turbine governor with a very slow regulation in the
case of a slight fluctuation of speed, and a rapid one with a greater fluctuation,
substantially herein described and according to the accompanying drawings.
Secondly. The combination of a governor of great power, which enables the governor
to move heavey gates, substantially herein described and according to the accom-
panying drawings.
Thirdly. The simplicity and compactness of the general construction of the
governor, substantially herein described and according to the accompanying
drawings.
