Improvements in Governors for Steam Engines.
I, WILLIAM EDWIN HEYS, of 70, Market Street, Manchester, in the County of
Lancaster, Chartered Patent Agent, 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:-
In the larger sizes of the ordinary types of governor combined with valve, for
steam engines, some of the moving parts are subject to considerable wear, princi-
pally owing to inefficiency in the lubrication. And, because of the absence of
convenient means for the adjustment of this wear, great trouble and expense
have to be incurred in repairing and replacing the worn parts in consequence of
the difficulty and inconvenience experienced in handling the considerable weights
of the governor.
The present improvements have been designed to avoid these defects and will
be hereinafter described with reference to the accompanying drawings in which:-
Figure 1 represents a sectional side elevation;
Figure 2, a sectional plan of the muff and yoke; and
Figure 3, a sectional elevation of the yoke and muff and of the means whereby
their motion is communicated to the valve.
Figures 2 and 3 are drawn to a larger scale.
W W, are the governor balls; M, the muff; Y, the yoke; F, the frame cast
or secured upon the cover of the valve V; B, a bridge forming the bottom support
for the vertical spindle $; 1', the driving pulley; D, the driving shaft; and G, the
mitre or bevel gearing between the shaft 1) and the spindle S.
The bridge B, of sufficient strength to carry steadily the rotating masses of the
governor, is bolted to the frame F and is provided with a step bearing A for the
spindle S. This bearing is constructed so that it may be adjusted by the set-
screw Qin case of wear, so as to provide for the constant true engagement of the
gear wheels G. Of these gear wheels, the bevel pinion G¹ is keyed upon the
spindle S, and the wheel G upon the shaft 1), so that the pinion is underdriven
as shewn by Figure 1, and consequently, if wear should occur in the step bear-
ing A, the pinion will move away from the wheel G, to the extent of the amount
of wear.
With the usual opposite arrangement, that is to say with the arrange-
ment of the pinion above the produced axis of the shaft D, any wear in the footstep
brings the weight of the rotating masses upon the wheel G', in proportion to
the amount of wear.
The pulley end (preferably) of the driving shaft D, runs in an adjustable bear-
ing E upon each side of which there is fitted an adjustable collar C, whereby the
true engagement of the vertical wheel G may be ensured. Means are thus pro-
vided for the adjustment in gear of each of the wheels G G¹ independently.
The throttle valve T is suspended from the governor sleeve or muff M, by

page_text: means of its spindle H, the cross head I, the two rods R R suitably guided at J J,
and the yoke Y. The rods R R are adjustable in length by their screwed ends
and the nuts N N, to allow the position of the valve T to be varied if required.
The yoke Y is constructed in halves which are connected by bolts passing through
the lugs KK, and fits upon the liner 0, which is also constructed in halves.
This liner may therefore be renewed when worn, in a short time and at a small
cost.
The construction of the frame F, as illustrated by Figure 1, readily permits
access to the gearing G G and the bearing A.
Effective lubrication of all the moving parts is provided for by the lubri-
cators L L.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is:-
1. A combined governor and valve for steam engines, constructed arranged and
operating substantially as hereinbefore described and as illustrated by the accom-
panying drawings.
2. In a combined governor and valve for steam engines, constructing and
arranging the vertical spindle bearing adjustably in a bridge piece, substantially
as hereinbefore described and as illustrated by the accompanying drawings.
3. In a combined governor and valve for steam engines, the construction and
arrangement of an open frame F, carrying the bridge 13, and being secured upon
the valve cover, substantially as herein before described and as illustrated by the
accompanying drawings.
Dated this Fourth day of November A.D. 1898.
