page_text: We SETH DAWSON and JAMES DAWSON of Bankside Iron Works Mossley in the
County of Chester Engineers do hereby declare the nature of this Invention to be
as follows:-
=
Our Invention relates to the Governors which at the present time are principally
employed in the regulation of the speed of steam machinery. In such governors
as ordinarily constructed suspended weights revolving around an axis are free to
move further away from or nearer to such axis as the speed of revolution increases
or decreases as is well understood. In such governors as constructed in accordance
with our invention we so mount each weight as that it is compelled to move in a
direction around a pivot which is carried by the governor spindle and is situated
some distance from the axis of revolution and we connect the said weight by
means of a link or of links with a sliding sleeve the connection of the weight with
such sleeve being nearer to the said axis than the said pivot. In a suitable
construction the pivots or the weights are carried by arms which project * from
the governor spindle and the radius rod or link which is mounted to turn upon
each pivot is attached by its outer end to a weight. The said weight is connected
by two side links with a sleeve which slides upon the spindle so that as the
weights move away from the axis of revolution the said sleeve is raised. The said
sleeve may be made more or less heavy according to the requirements or may be
adapted to be loaded with weights. The said sleeve is connected in the usual or
in a suitable manner with the valve rod, or with the parts which control the admis
sion of steam to the engine or which otherwise regulate the speed of the engine or
machinery or the said sleeve is connected by means of links or by suitable means
with a second sleeve which is arranged to slide upon the governor spindle or upon
a part concentric therewith the said second sleeve imparting the necessary move-
ments to the regulating connections. The said pivots may be adjustable in distance
from the axis of revolution. We prefer that the radius rods which carry the
weights shall be about parallel with the axis of revolution when the governor is
running at its normal speed but we do not confine ourselves to this.
arranged we believe that the improved governor will be very "sensitive."

We SETH DAWSON and JAMES DAWSON of Bankside Iron Works Mossley in the
County of Chester, Engineers 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 and accompanying drawings:-
"
Our Invention relates to the Governors which at the present time are principally
'employed' in the regulation of the speed of steam machinery. In such governors
as ordinarily constructed suspended weights revolving around an axis are free to
move further away from or nearer to such axis as the speed of revolution increases
or decreases as is well understood. In such governors as constructed in accordance
with our invention we so .mount each weight as that it is compelled to move in a
direction around a pivot which is carried by the governor spindle and is situated
some distance from the axis of revolution and we connect the said weight by
means of a link or of links with a sliding sleeve the connection of the weight with
such sleeve being nearer to the said axis than the said pivot. Our Invention
will be best understood when more fully described with reference to the accom-
panying sheet of drawings which represent a governor constructed in accordance
with our invention. In the said drawings Fig. 1. represents a frout elevation of
the governor and Fig. 2 being a side view illustrating the arrangement of the
links. In Fig. 1 a. is the stand which may be of any suitable form and construc
tion. In bearings in this stand is mounted the vertical spindle b.;of the governor.
Upon this spindle is fixed a cross piece c. which is formed with two arms which
project in opposite directions from the spindle. Upon each arm is mounted a
cross pivot bar d. upon which two links e. e. are hinged. The upper ends of these
links carry weights f. and are jointed to the outer ends of a second pair of links g.
The inner ends of the links g. are jointed to a heavy sleeve weight h. which is
mounted to slide vertically upon the governor spindle and constitutes a load
which has to be lifted by the centrifugal force arising from the revolution of the
weights ff. around the vertical axis. The upper end of the weight h. is coupled
to a rod . which is connected with the parts which control the admission of steam
to the engine or which otherwise regulate the speed of the engine or machinery.
The parts h. and i. are coupled in such a manner as that the part h. can revolve
without imparting rotatory motion to the rod i. The method of coupling which
we prefer to use is illustrated by Fig. 3. A recess k. is formed in the upper end
of the weight h. and encloses a spiral spring 1. which presses upward a cupped
diac m. until it bears against a washer n. A collar upon the end of the rod i
occupies the space enclosed by the said cupped disc and a washer in the upper
end of the said recess and the parts are so fitted as that the cupped disc and
washer can revolve easily without turning the said collar. The spring 1. relieves
the rod from excessive shock at the times when the weight rises suddenly as for
example at the times when the engine is started the spring permitting the disc m
to yield downwards at such times. Any suitable means may be used for driving
the governor-that is to say for connecting the governor spindle with a revolving
part of the engine or machine to which the governor is applied. In the example a
slotted crank o adapted to engage with a pin upon the engine crank or crank shaft

page_text: is fixed upon a cross shaft which is connected by means of bevel gearing-indicated
by dotted lines with the governor spindle. When the said spindle has attained
the velocity of revolution for which the governor is adapted the weights f. f. move
outward and the links e. e. raise and sustain the weight h. which then rises and
sinks accordingly as the velocity may increase or decrease as in the cases of ordi-
nary governors. The governor may be adjusted to suit different speeds within
certain limits by shifting the pivot bars d. d. upon the cross piece c. and fixing
them in positions nearer to or further from the axis of revolution. Any suitable
form of load may be used for the weight h. and may be in one or more parts or
spring might take the place of the weight h. especially in cases wherein the axis
of revolution would be horizontal. The said weight might be connected with a
sleeve mounted to slide upon the spindle and connected with the controlling valve
or part as in some forms of governor. In the example the bars d. can be fixed in
their adjusted positions by means of jamb nuts d¹ screwed on the crosspiece or
other suitable means of adjustment may be adopted such for example as set screws.
If preferred a single link fixed to the weight f. or formed in one piece with such
weight may take the place of the two links e. e. or of the links g. g. as will be
well understood.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
(1.) The combination of parts forming the governor substantially as and for
the purposes set forth and indicated herein before and in the accompanying
drawings.
(2.) A revolving governor having weights connected by links or hinged rods
with a vertically sliding load and carried by radius links or rods which turn upon
fulcra which are further removed from the axis of revolution than the centres of
connection with the said load substantially as set forth and indicated.
(3.) In a governor for steam and other machinery the weights connected by the
links g. with a load h. and carried by links or arms e. which are mounted upon
pivots which revolve in a larger circular path than the joints of the links g. with
the load substantially as set forth and indicated.
