County of Middlesex, for an Invention of "IMPROVEMENTS IN GOVERNORS FOR
STEAM AND OTHER ENGINES, PARTLY APPLICABLE TO OTHER PURPOSES."

This Invention has reference to improvements in "cataract
kind described in the Specification of Letters Patent granted to me the 10th day of
governors of the
March, A.D. 1879, No. 943. According to my present improvements, the pumps
that discharge the liquid for supplying the cataract are arranged with their axes
radial to a centre around which they revolve.
The pump chambers or barrels are formed in a metal disc or body I will call the
pump disc; it is driven by a pulley or by other suitable means from the prime
mover, to be controlled and thus caused to rotate about a fixed coned centre in
which are formed the suction and delivery chambers. The piston rods of the
pumps according to one arrangement are each connected by a pin or bolt to two
discs, one on cach side of the pump disc. These discs, which I will call the eccentric
dises, rotate about a common axis, but are eccentric to the pump disc. On each or
some of the pins or bolts to which the piston rods are connected, or on some special
pins, are eccentrics. Each of these eccentrics works in a hole or recess in its side of
the pump disc. Thus as the pump disc rotates it through these eccentrics, and the
pins or bolts carries round the eccentric discs, and as each pin or bolt in revolving
gradually recedes from or moves towards the axis of the pump disc, the piston
connected to such pin or bolt is correspondingly operated. The delivery chamber
is in communication with an adjustable regulating valve, also with a cylinder
fitted with a piston suitably loaded, so that the variations in the supply of liquid
to such cylinder acting upon the piston through it control the prime mover.
A convenient mode of loading the piston where springs are used is as follows:-
The spring acts on a trunnion or shaft connected by means of levers and links to

page_text: the piston rod, and for varying the pressure the spring may be tightened up or
loosened as required. The amount of leverage also acting upon the spring through
the motion of the piston rod may be varied by means of a link connected to the
piston rod, and centred at its one end to a shifting carriage or bracket, which, when
shifted, alters the centre of motion of the piston rod, and through it causes the
fulcrum of the lever acting upon the spring to be shifted. The apparatus is
contained in a tank filled with liquid, and as the revolving parts wear, they may
be screwed up to the coned fixed centre. Instead of. being driven by a pulley in
connection with the prime mover, the apparatus may be driven by a spur wheel
gearing into cogs formed on the peripheries of the pump disc and eccentric discs.
In a modification in which three pumps only are used, six eccentric rings or
straps are carried by fixed centres, eccentric to the axis of the pump disc; these
rings or straps are connected together in pairs by pins or bolts, each passing through
a hole in one of the pump pistons, so that as the pump disc and eccentric rings or
straps revolve, the said pistons are operated as already described.
As is obvious, various arrangements of apparatus may be constructed to operate
on the principle of my Invention, as above set forth, and apparatus according
thereto may be arranged for drawing and forcing liquids or fluids for various
purposes and for measuring.

This Invention has reference to improvements in "
kind described in the Specifiation of Letters Patent granted to me the 10th day of
governors of the
March, A.D. 1879, No. 943. According to my present improvements the pumps
that discharge the liquid for supplying the cataract are arranged with their axes

mover,
The pump chambers or barrels are formed in a metal disc or body I will call the
pump dise; it is driven by a pulley or by other suitable means from the prime
to be controlled and thus caused to rotate about a fixed coned centre, in
which are formed the suction and delivery chambers. The piston rods of the .
pumps, according to one arrangement, are each connected by a pin or bolt to. two
discs, one on each side of the pump disc. These discs, which I will call the
eccentric discs, rotate about a common axis, but are eccentric to the pump disc.
On each or some of the pins or bolts to which the piston rods are connected, or on
special pins, are eccentrics. Each of these eccentrics works in a hole or recess in
the pump disc. Thus as the pump disc rotates, it, through these eccentrics and
the pins or bolts, carries round the eccentric discs, and as each pin or bolt in
revolving gradually recedes from or moves towards the axis of the pump disc, the
piston connected to such pin or bolt is correspondingly operated. The delivery
chamber is in communication with an adjustable regulating valve, also with a
cylinder fitted with a piston suitably loaded, so that the variations in the supply
of liquid to such cylinder acting upon the piston through it, control the prime
mover.
A convenient mode of loading the piston where springs are used is as follows:-
The spring acts on a trunnion or shaft connected by means of levers and links to
the piston rod, and for varying the pressure the spring may be tightened up or
loosened as required. The amount of leverage also acting upon the spring through
the motion of the piston rod may be varied by means of a link connected to the
piston rod, and centred at its one end to a shifting carriage or bracket, which when
shifted alters the centre of motion of the piston rod, and through it causes the
fulcrum of the lever acting upon the spring to be shifted. The apparatus is
contained in a tank filled with liquid, and as the revolving parts wear, they may
be screwed up to the coned fixed centre. Instead of being driven by a pulley in
connection with the prime mover, the apparatus may be driven by a spur wheel
gearing into cogs formed on the peripheries of the pump disc and eccentric discs.
In a modification in which three pumps only are used, six eccentric rings or
straps are carried by fixed centres eccentric to the axis of the pump disc; these six
rings or straps are connected together in pairs by pins or bolts, each passing through
a hole in one of the pump pistons, so that as the pump disc and eccentric rings or
straps revolve, the said pistons are operated as already described.
As is obvious, various arrangements of apparatus may be constructed to operate
on the principle of my Invention, as above set forth, and apparatus according
thereto may be arranged for drawing or forcing liquids or fluids for various
purposes and for measuring.
Fig. 1, Sheet 1 of the Drawings, is a plan partly in section of my improved
multiple pump wherein the connecting discs are placed with their axes between two

page_text: pump barrels, and Fig. 2, Sheet 1, shows two longitudinal vertical half sections of
the same, one taken in the line A, B, of Fig. 1, Sheet 1, through the centre of a
pump barrel, and the other in the line C, D, of Fig. 1, through the centre of a pair
of connecting discs. a, a, are the pump chambers or barrels formed in the metal
disc or body b; c is a pulley secured on the extension 6 of the pump disc b for
driving the same; d is a fixed coned centre around which the pump disc rotates,
and in which are formed the suction passage and chamber e, and the delivery
passage and chamber f. The pistons of the pumps are each connected by means of
a pin or bolt to two rods or arms g pivotted at g¹ respectively, to two discs,
rings, or straps i and j, which rotate on similar fixed portions i, j, of the apparatus
having their centres excentric to the centre of the pump disc. The excentric
discs i, j, are connected to the pump disc by means of connecting discs k, l, fitting
into recesses formed in the pump disc so as to rotate therein, and having pins or
bolts ¹³ connected to the excentric discs i and j, and passing through the connecting
disks eccentrically to their centres, according to the length of stroke of the pistons;
dare pillars or supports for carrying the upper fixed plate i forming the eccentric
portion i¹.
As the pump disc becomes worn, it may be screwed up to the coned centre & by
Instead of driving
means of the screws and nuts d acting upon the upper plate i¹.
the pump disc by a pulley c, it, and the eccentric disks i, j, may be driven by a
pinion gearing into teeth formed on their outer extremities, as shewn in dotted
lines. The apparatus may be placed in a tank or other receptacle containing water
or other liquid.
It will be understood that as the pump disk is rotated the pistons are caused to
reciprocate, their movement being outward when passing the suction chamber side
of the centre d so as then to draw liquid or fluid into them through el, which liquid
or fluid as they pass round the other side of the centre is by the inward
movement of the pistons forced into the outlet chamber f through a hole or holes,
such as e¹; x is an interposed layer of antifrictional material.
This pump may be modified by dispensing with one of the eccentric disks i or j.
This improved valveless pump, in addition to its use as part of one of my patent
governors, is applicable also to various other purposes, such as for drawing and forcing
liquids and fluids, measuring, air compressing, hydraulic governors, etcetera, etcetera.
Sheets 2 and 3 show one of my improved governors constructed with a
modification of the multiple pump just described.
Fig. 1, Sheet 2 of the Drawings, is longitudinal vertical section of my improved
governor, made with three pump barrels or chambers.
Fig. 2, Sheet 3, is a sectional plan of the same taken in the line A, B, of Fig. 1,
Sheet 2, and
Fig. 3, Sheet 2, is a vertical section of the compensated spring loading apparatus
in the line C. D. of Fig. 1. .
a, a, are the pump chambers or barrels formed in the pump disc b, with their
axes radial to its centre; c is a grooved pulley formed or fitted around the pump
disc b, whereby the same is revolved from the prime mover to be controlled; & is a
fixed coned centre formed with a suction chamber e and a delivery chamber fin
communication with the pumps a, a. The suction chamber e opens into a tank
containing liquid, whilst the delivery chamber f leads to an adjustable regulating
valve m, and is also in connection by means of a pipe f¹ with a cylinder n fitted
with a piston n¹, whose rod n² is connected to a lever s which operates the throttle
valve or other regulating apparatus of the engine or prime mover to be controlled.
The pistons a¹ of the pumps a are each connected to a pair of eccentric straps i, j,
by bolts h passing through them. The straps i, j, revolve in similar eccentric parts i, j,
on each side of the pump disc, and as the eccentric discs and pump disc revolve
together the pistons of the pumps are caused to reciprocate and so draw and force
liquid through the holes e¹ and chambers e, f, in quantities according to the speed at
which the pump disc is driven. As the pump disc b wears it may be screwed up
to the coned fixed centre d by the tightening nut d¹.

page_text: The piston n¹ is acted upon by the varying supply of liquid from the delivery
chamber f, and by means of its rod n³ in connection with the lever n³ controls the
prime mover.
The piston is suitably loaded by means of a spring o which is connected to and
acts upon a shaft p carried by a bracket p¹ fitted to the cylinder n as shewn, so
that it may be fixed at any angle required. Each end of the shaft p is formed with
teeth p, similar teeth being formed in two arms or levers q, q, into which the other
teeth fit, so as to fix the arms or levers to any angle.required. Links r, r, connect
the arms or levers q, q, to a lever 8 carried by a sleeve collar or supporting piece 8¹
pivotted at 82 to the bracket p¹. The lever s is connected to the piston rod at s³,
and the amount of leverage acting upon the spring o through the motion of the
piston rod may be varied by means of a radius rod or link t connected to the piston
rod, and to a shifting carriage or bracket carried by the bracket p¹. This
carriage or bracket u is shifted by means of the screw u¹ and nut u², and thereby
alters the path taken by the piston rod's top end, and shifts the fulcrum of the
lever 8 acting upon the spring to the required extent. The lever n³ is connected to
the throttle valve or other controlling apparatus of the engine to be controlled, and
is carried by a shifting bracket v, whereby the movement of the said lever may also
be varied by means of the screw w. x is a tank filled with liquid, and inside which
the apparatus may be fixed. As the revolving pump disc b wears, it may be screwed
up to the coned fixed centre d by nuts d², as shewn in Fig. 1, Sheet 2.
Instead of the compensated spring loading apparatus as described being used, a
simple weight y may be substituted at one end of the lever s, as shewn in dotted lines.
Fig. 4, Sheet 4, shews a modification of my improved governor as operated by a
revolving multiple pump, such as hereinabove described and shewn on Sheet 1 of
the Drawings.
The mode of operating this arrangement of governor is similar to that described
with reference to Figs. 1 to 3, Sheets 2 and 3, similar letters of reference indicating
like parts, the only difference being, besides the form of pump, that in this case the
apex of the coned centre points upwards instead of downwards. Fig. 5, Sheet 4, is
a section of the adjustable regulating valve which is placed in communication with
the delivery chamber through the passage f¹. Figs. 6 to 9 (Sheets 5 and 6)
show another modification of my improved governor. Fig. 6, Sheet 5, being a
longitudinal vertical section; Fig. 7 is a vertical cross section of the spring com-
pensation arrangements in the line A, B, of Fig. 6, Sheet 5, and Fig. 8 (Sheet 5), a
section of the adjustable regulating valve. Fig. 9, Sheet 6, shews a double sectional
plan taken in the lines C, D, and E, F, of Fig. 6.
The mode of operating this modification of apparatus is similar to that described
in the former arrangements, with the exception that the connecting discs and l are
arranged with their axes in a plane comnion to the axis of a pump barrel instead
of between the pump barrels, thereby affording a lesser number of working parts
to be used.
The adjustable regulating valve m is screwed to a seating m¹, Fig. 9, Sheet 6, in
communication with the delivery passage f¹.
Having described the nature of my said Invention, and the manner of carrying
it into practical effect, I would have it understood that what I claim as secured
to me under the Letters Patent hereinbefore first in part recited is,―
1. The combination of a conical centre or axis containing ports and passages to
suction and delivery chambers, with a revolving disc or pump body containing a
number of pump chambers or barrels radial to the said conical centre or axis, and
fitted with pistons, substantially as described.
2. The combination of a hollow conical centre or axis containing suction and
delivery ports, passages, and chambers, a revolving disc or pump body containing a
number of pump chambers or barrels radial to the said conical centre or axis, and
containing pistons and one or more revolving discs, rings, or straps running upon
fixed eccentrics and connected to said pistons by pins and links, substantially as
described.

page_text: 3. The combination with a revolving disc or pump body containing radiating
pump chambers or barrels and pistons, and able to rotate on a hollow conical
centre or axis, and one or more revolving discs, rings, or straps, running upon fixed
eccentrics and connected to said pistons of connecting discs to interlock the pump
disc or body with the eccentric discs, rings, or straps, in such a way that all may
revolve together, substantially as described.
4. The combination with a hollow conical centre or axis containing suction and
delivery chambers, and on which revolves a disc or pump body, containing radiating
pump chambers or barrels of pinions or pullies fixed upon an axial extension of the
pump disc or body, or gearing into teeth on the circumference of the pump body
and eccentric discs, rings, or straps, designed to impart rotary motion to the
whole system, substantially as described.
5. In a governor of the kind above described, the method of loading the
hydraulic ram by springs, fitted with an adjustable compensating arrangement for
keeping the load on said ram uniform at all points of the stroke, through the
intervention of a shifting fulcrum operated by a radial rod, substantially as
described.
6. The improved governors for steam and other engines, constructed, arranged,
and operating substantially as shewn on and described, with reference respectively
to Sheets 2 and 3, and to Sheets 4 to 6 inclusive, of the accompanying Drawings.
