IMPROVEMENTS IN AND APPARATUS For TRANSMITTING ROTARY MOTION TO DYNAMO-
ELECTRIC MACHINES WHICH IMPROVEMENTS AND APPARATUS ARE ALSO APPLICABLE
TO TRANSMITTING ROTARY MOTION FROM ELECTRO-DYNAMIC MACHINES to be as
follows:-
My invention relates firstly to and consists firstly in arrangements for transmit-
ting rotary motion from steam engines or other motors to the armatures and other
revolving parts of dynamo-electric machines. By my said invention I am enabled
to rotate the armatures and other revolving parts of dynamo-electric machines at
a speed greater or less than that of the steam engines or other motors from which
the said armatures and other revolving parts receive rotary motion.
In carrying my invention into effect, when I desire that the armature and other
revolving parts of the dynamo-electric machine to which my invention is to be
applied shall be rotated at a speed greater than that of the steam engine or other
motor from which such armature and other revolving parts aforesaid receive rotary
motion, I mount a disc or plate upon the axle or shaft of the steam-engine or
other motor above mentioned and in the face of the said disc I form grooves
or slots which grooves or slots extend across the face of such disc-The armature
and other revolving parts of the dynamo-electric machine I place so that the
axis thereof is parallel to the axis of the shaft or axle of the steam-engine or other
motor above referred to Upon the shaft or axle of the armature and other revolv-
ing parts of the dynamo-electric machine I mount a disc plate or arms secured to
which disc plate or arms are pins or studs upon which pins or studs are or may be
mounted bowls rollers or blocks which pins, studs bowls, rollers or blocks pass into
the grooves or slots formed in the disc or plate previously mentioned and are acted
upon by the sides of such grooves or slots-When the disc or plato above men-
tioned is rotated the grooves or slots formed therein acting upon the pins studs
ונDo

page_text: bowls rollers or blocks previously mentioned will cause the armature and other
revolving parts of the dynamo-electric machine to be rotated, each revolution of
the disc or plate before mentioned provided with grooves or slots causing the
armature and other revolving parts of the dynamo-electric machine to make a
number of revolutions corresponding to the relative proportions of the disc or plate
provided with grooves or slots and the circle described by the pins studs bowls
rollers or blocks above referred to and the form of the grooves or slots aforesaid-
When I desire that the armature and other revolving parts of the dynamo-
electric machine shall be rotated at a speed less than that of the steam-engine or
other motor from which such armature and other revolving parts receive rotary
motion I mount the disc plate or arms carrying the pins studs bowls rollers or
blocks above referred to upon the shaft or axle of the steam-engine or other motor
aforesaid and I mount the above-mentioned disc or plate provided with grooves or
slots upon the shaft or axle of the armature and other revolving parts of the
dynamo-electric machine-By this arrangement the armature and other revolving
parts of the dynamo-electric machine will be caused to be rotated at a speed less
than that of the steam-engine or other motor above-mentioned each revolution of
the disc plate or arms above referred to provided with pins studs bowls rollers
or blocks causing the armature and other revolving parts of the dynamo-electric
machine to make a portion of a revolution corresponding to the relative propor-
tions of the disc or plate provided with grooves or slots and the circle described by
the pins studs bowls rollers or blocks above referred to and the form of the grooves
or slots aforesaid. In order to maintain the axis of the armature and other
revolving parts of the dynamo-electric machine in correct working position parallel
with the axis of the steam-engine or other motor which rotates the armature
and other revolving parts aforesaid I mount the dynamo-electric machine upon a
frame or frames provided with hinges or slides so arranged that such frame or
frames may be raised or lowered by screws or other suitable means so that the axle
or shaft of the armature and other revolving parts of the dynamo-electric machine
may be readily adjusted relatively to the axle or shaft of the steam-engine or other
motor above mentioned or may be readily removed for examination cleaning or
repair In some cases I propose to mount the dynamo-electric machine upon
à frame or frames turning upon hinges and to sucli frame or frames I secure
one end of a rod the other end of which rod embraces the shaft or axle of the
steam-engine or other motor before mentioned so that the axis of the armature
and other revolving parts of the dynamo-electric machine will be kept at a constant
distance from the axis of the shaft or axle of the steam-engine or other motor-
I provide the rod above mentioned with screws and nuts or other suitable appli-
ances by which screws and nuts or other suitable appliances the axle or shaft of
the armature and other revolving parts of the dynamo-electric machine may be
adjusted in position relative to the axle or shaft of the steam-engine or other motor
above mentioned.
A further part of my invention relates to and consists in a method of and
arrangements for lubricating the pins studs bowls rollers or blocks previously
referred to-According to one method of carrying this part of my invention into
effect, I form in each of the pins or studs above mentioned a hole which com-
municates at one end with the surface of the pin or stud aforesaid upon which is
or may be mounted one of the bowls rollers or blocks above referred to The other
end of the hole aforesaid communicates by means of a pipe or tube with the inner
surface of a ring of U section the open part of which ring is towards the axis of
the armature and other revolving parts of the dynamo-electric machine-When
oil or other lubricant is poured into the said ring when the armature and other
revolving parts of the dynamo-electric machine are rotating such oil or other lubri-
cant will by means of the pipe and hole above referred to be carried by centrifugal
force to the pin, stud bowl, roller, or block to be lubricated-In order to lubricate
the bowls rollers or blocks previously mentioned I form in or secure upon the disc

page_text: or plate above mentioned provided with grooves or slots in which grooves or slots
the bowls rollers or blocks slide, a ring of an U section the open part of which
ring is towards the axis of the disc or plate above mentioned and which ring serves
to contain oil or other lubricant into which oil or other lubricant the bowls rollers
or blocks above referred to will dip as they move within the grooves or slots above
IDentioned The centrifugal force consequent upon the rotation of the disc or plate
aforesaid cause the oil or other lubricant before mentioned to be equally distributed
within the ring above referred to as the disc or plate above mentioned is rotated.
My invention further consists in the application of the arrangements above
described to the transmission of rotary motion from electro-dynamic machines to
machinery or apparatus to which such electro-dynamic machines supply motive
power.

Apparatus are also Applicable to Transmitting Rotary Motion
from Electro-dynamic Machines.
I, HERBERT LINDLEY of Sandon Works, St Simon Street Salford in the County
of Lancaster 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 :-
My invention relates firstly to, and consists firstly in, arrangements for trans-
mitting rotary motion from steam engines or other motors to the armatures and
other revolving parts of dynamo electric machines.
By my said invention I am enabled to rotate the armatures and other revolving
parts of dynamo-electric machines at a speed greater or less than that of the steam
engines or other motors from which the said armatures and other revolving parts
receive rotary motion.
In carrying my invention into effect, when I desire that the armatures and other
revolving parts of the dynamo electric machines to which my invention is to be
applied, shall be rotated at a speed greater than that of the steam engine or other
motor from which such armature and other revolving parts aforesaid receive
rotary motion, I mount a disc or plate upon the axle or shaft of the steam engine
or other motor above mentioned and in the face of the said disc I form grooves
or slots, which grooves or slots extend across the face of such disc.
The armature and other revolving parts of the dynamo-electric machine I place
so that the axis thereof is parallel to the axis of the shaft or axle of the steam
engine or other motor above referred to.
Upon the shaft or axle of the armature and other revolving parts of the dynamo-
electric machine I mount a disc plate or arms, secured to which disc plate or arms
are pins or studs, upon which pins or studs are or may be mounted, bowls, rollers,
or blocks, which pins, studs, bowls, rollers, or blocks, pass into the grooves or slots
formed in the disc or plate previously mentioned and are acted upon by the sides
of such grooves or slots.
When the disc or plate above-mentioned is rotated, the grooves or slots formed
therein acting upon the pins, studs, bowls rollers or blocks previously mentioned
will cause the armature and other revolving parts of the dynamo-electric
machine, to be rotated, each revolution of the disc or plate before mentioned
provided with grooves or slots, causing the armature and other revolving parts of
the dynamo-electric machine to make a number of revolutions corresponding to the
relative proportions of the disc or plate provided with grooves or slots and the
circle described by the pins, studs, bowls, rollers or blocks above referred to and
the form of the grooves or slots aforesaid. When I desire that the armature and
other revolving parts of the dynamo-electric machine shall be rotated at a speed
less than that of the steam engine or other motor from which, such armature and

page_text: other revolving parts receive rotary motion, I mount the disc plate or arms carrying
the pins, studs, bowls, rollers, or blocks, above referred to upon the shaft or axle of
the steam-engine or other motor aforesaid, and I mount the above mentioned disc or
plate provided with grooves or slots upon the shaft or axle of the armature and
other revolving parts of the dynamo-electric machine.
By this arrangement the armature and other revolving parts of the dynamo-
electric machine will be caused to be rotated at a speed less than that of the
steam-engine or other motor above mentioned, each revolution of the disc plate, or
arms, above referred to, provided with pins, studs, bowls, rollers, or blocks, causing
the armature and other revolving parts of the dynamo electric machine to make a
portion of a revolution corresponding to the relative proportions of the disc or
plate provided with grooves or slots, and the circle described by the pins, studs,
bowls rollers, or blocks above referred to, and the form of the slots or grooves
aforesaid.
In order to maintain the axis of the armature and other revolving parts of the
dynamo electric machine in correct working position parallel with the axis of the
steam engine or other motor which rotates the armature and other revolving parts
aforesaid, I mount the dynamo electric machine upon a frame or frames provided
with hinges or slides so arranged that such frame or frames may be raised or
lowered by screws or other suitable means so that the axle or shaft of the armature
and other revolving parts of the dynamo-electric machine may be readily adjusted
relatively to the axle or shaft of the steam-engine, or other motor above-mentioned
or may be readily removed for examination, cleaning or repair.
In some cases I propose to mount the dynamo electric machine upon a frame or
frames turning upon hinges, and to such frame or frames I secure one end of a. rod,
the other end of which rod embraces the shaft or axle of the steam-engine or other
motor before mentioned so that the axis of the armature and other revolving parts
of the dynamo-electric machine will be kept at a constant distance from the axis of
the shaft or axle of the steam engine or other motor.
I provide the rod above mentioned with screws and nuts or other suitable
appliances, by which screws, and nuts or other suitable appliances the axle or
shaft of the armature and other revolving parts of the dynamo-electric machine
may be adjusted in position, relative to the axle or shaft of the steam-engine or
other motor above-mentioned.
In order to shew how my invention may be carried into effect I have hereto
appended a sheet of drawings which I will now proceed to describe.
Fig. 1 is a front elevation of the apparatus showing engine, dynamo, foundation
beams &c.
Figs. 2 and 3 are plan and end view respectively showing the engine shaft and
dynamo spindle with the discs thereon.
Figs. 4 and 5 are end view and section showing the gearing drawn to larger
scale.
Fig. 6 is a diagram showing the paths of the centres of the pins and rollers
across the larger disc. The same letters refer to the same parts in each of these
figures.
A is the engine shaft, or the shaft of any other source of power. B. is the dynamo
spindle. C is the larger disc on shaft A. also serving as a fly wheel for the engine,
& D is a plate secured to disc C and containing the grooves in which the rollers or
slide blocks roll or slide. E is the smaller disc on the dynamo spindle with its
pins and roller g. which are shown to a larger scale in Figs. 4 & 5.
The diagram, Fig. 6, shows the paths of the rollers and pins across the face of
the larger disc, thus the pin 1 traverses the groove 11 11, the pin 2 the groove 2¹ 2¹
and the pin 3 the groove 31 31. The direction of rotation of the discs and shafts,
and that of the pins in the grooves being indicated by arrows.
It will be seen that as the larger disc rotates, the pins and rollers pass along the
grooves in the disc, and the smaller disc and its shaft will have a uniform and
regular rotative motion of twice the angular velocity of the larger disc and shaft,

page_text: In order to insure that the shafts of the engine & dynamo respectively, shall be
kept at the correct distance apart, so that the paths of the centres of the pins and
rollers shall pass through the centre of the engine shaft I cause the dynamo to be
mounted on a cradle or carriage H, Figs. 1. 2. and 3, pivotted at one end on a
shaft I, carried in bearings J, on the foundation beams K on which beams K also
rests the engine.
The end of the cradle H next the engine, has an eye or boss m connected to a
tie rod L which has at its upper end a bearing N through which works the engine
shaft A, or the boss of the disc C may be made to work in the bearing a shown in
the drawing. The length of this tie rod L remaining constant, insures that the
correct distance apart of the shafts A and B shall be maintained in case of either
of the bearings of the engine or dynamo, wearing, or if the engine shaft should lift
or tend to lift, or move about whilst the engine is working.
A spring O serves to carry the weight of the cradle H with the dynamo, and
relieves the tio rod L, and bearing N of any unnecessary strain but that of correctly
keeping the centres of the engine and dynamo spindle. Screws P, see Fig. 2, are
provided to adjust and steady the cradle sideways.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
I claim is
1st The use of the swinging cradle H as described & illustrated in combination
with the mechanism. described for the purpose of transmitting an increased or
decreased velocity ratio between a prime mover and any machine to be driven by
same.
2nd The combination of a prime mover and dynamo with the cradle and driving
mechanism as illustrated & described.
3rd The general construction and arrangement of the mechanism and parts
substantially as illustrated and described in the drawings.
