WALTER JOHN LLOYD of the firm of Lloyd Brothers of Harborne in the
County of Stafford Manufacturers "IMPROVEMENTS IN TRICYCLES AND OTHER
VELOCIPEDES
I will describe my improvements in connection with a tricycle.
In order to facilitate the motion of the tricycle in a curve and to secure the
driving of both wheels when the tricycle moves in a straight line I adopt the
following arrangement of parts. The travelling wheels are not fixed on the shaft
but are capable of rotating thereon. Near the hub of each of the travelling wheels
a chain wheel is fixed on the shaft, the said chain wheel receiving motion from the
crank shaft. The hub of the chain wheel has two cylindrical holes parallel to the
shaft, the said holes extending from the outer face to nearly the inner face of
the hub. Cylindrical plugs shorter than the holes are placed in the said holes,
a coiled spring at the bottom of each hole forcing the plugs outwards. The outer
ends of these plugs bear against the hub of the travelling wheel. In the face of
the travelling wheel against which the plugs bear is a series of depressions suitable
for the reception of the ends of the plugs. These depressions are of a cylindrical
figure on one side but are inclined on the other side so that when the motion
of the shaft is such that the plugs bear against the cylindrical sides of the holes
in the hubs of the wheels the said wheels are carried round with the shaft but
when the motion of the shaft is in the opposite direction the plugs slide up the
inclined sides of the holes in the hub of the travelling wheel and the said wheel
is not carried round by the shaft. By this arrangement both wheels are driven by
the shaft when the tricycle moves in a straight line but when moving in a curve
the motion of the shaft is communicated to one only of the travelling wheels the

page_text: other travelling wheel resting or moving at the rate required by the curve in which
the tricycle is moving.
In order to obtain two different speeds I employ the following arrangement of
parts. On each end of the shaft of the travelling wheels, I fix a chain wheel
these chain wheels being of different diameters. On the ends of the crank shaft
I place chain wheels turning loosely on collars fixed on the ends of the said shaft.
These chain wheels are of the same diameter as the smaller chain wheels of the
travelling shaft. The crank shaft wheels and travelling shaft wheels are connected
by chains in the usual way
When the ends of the shafts having chain wheels of similar size are geared
together the travelling shaft rotates at the same speed as the crank shaft but
when the end of the travelling shaft having the chain wheel of larger diameter is
geared to the crank shaft the travelling shaft rotates at a less speed than the
crank shaft and power is thereby gained. The gearing mechanism is constructed
as follows:-
The crank wheels are loose on the collars at the ends of the shaft. The ends
of the shaft are hollow and in each of the said hollow ends a sliding bolt works.
In each bolt is an inclined groove parallel with its axis and in the collar on which
the wheel works is a slot having in it a key or tooth inclined on its underside.
The lower part of the key occupies the groove in the sliding bolt and when the
said bolt is pushed inwards it raises the key causing it to engage with one of a
series of notches in the hub of the chain wheel and thereby fixes it to the shaft.
The sliding bolts at the ends of the crank shaft are so coupled together that
when one is in action, the other is out of action and when in an intermediate
position, both are out of action. The crank shaft is thus made to drive the
travelling shaft at a greater or less speed or is wholly disconnected from it.
Or I obtain two speeds in the following manner. The chain wheel on one end
of the crank shaft and that on the same end of the travelling shaft are constructed
as follows. Each tooth of these wheels is provided with a supplementary tooth
on the side of the wheel, these supplementary teeth are capable of being turned
and fixed outwards, that is, from the centre, when they constitute a toothed wheel of
larger diameter than the normal wheel; or they may be turned inwards when they
are out of action and the normal wheel receives the chain. The wheel on the
travelling shaft is larger than that on the crank shaft. When the normal wheel
on the crank shaft is geared to the supplementary wheel on the travelling shaft,
the travelling shaft rotates at the same speed as the crank shaft. When the
supplementary wheel on the crank shaft is geared to the normal wheel on the
travelling shaft, the latter travels at a slower speed than the crank shaft and with
greater power. The supplementary teeth are raised when required by an arm
against which they are made to strike. The teeth of the normal wheels engage
with a less number of links of the chain than those of the supplementary wheels
I construct the steering apparatus in the following manner.
Instead of supporting the hind or steering wheel of the tricycle by means of a
vertical fork as usual, the head of which swivels in a bearing at the end of the
framing, I support the hind or steering wheel and construct the parts connected
with it in the following manner Instead of using a small hind or steering wheel
I use a hind wheel preferably of the same diameter as the driving or travelling
wheels on the cranked shaft. The said large hind wheel is furnished with a
horizontal axle projecting some distance on either side the wheel. The said axle
is supported at its extreme ends in curved bearing plates fixed to the rear ends
of the framing of the tricycle, which framing is thus made considerably broader
at its rear end than usual. The concave faces of the said fixed bearing plates are
turned to each other the curve of the said plates being struck from the middle of
the axle of the large bind wheel. The said concave bearing plates are slotted and
in the slots, sliding brasses or bearing blocks work. V shaped ribs on the upper
and lower sides of the slotted plates taking into V depressions in the bearing blocks.
In these sliding bearing blocks, the ends of the axle of the hind wheel are supported

page_text: and turn, spheres or balls or cylindrical rods being interposed between the axle
and the interior of the bearing blocks to reduce friction. The said balls or rods
are kept in their places in the bearing blocks by means of a cap or cover screwed
to the front of the said block.
By moving the sliding bearing blocks simultaneously in opposite directions
in their slots in the fixed bearing plates, the desired inclination can be given to the
large hind or steering wheel for guiding or steering the tricycle.
The steering mechanism is constructed as follows.
To each of the caps or covers of the bearing blocks in which the ends of the axle
of the hind wheel work, a connecting rod is jointed.
The inner ends of these connecting rods are jointed to the ends of a horizontal
lever turning on a centre situated under the seat for the driver.
To this lever the rod of the steering handle is jointed near one end of the said
lever. Or a steering handle at each side of the tricycle may be connected to the
lever described.
By operating upon the steering handle the lever is turned in one
direction upon its centre.
or other
This motion is transmitted through the connecting rods to the bearing blocks
of the axle of the hind wheel and a like motion is given to the said wheel so as to
effect the steering of the tricycle, the bearing blocks on the motion of the said
lever sliding in opposite directions in the slotted bearing plates as before described.
The improvements herein described may be applied to velocipedes having more
than three wheels

WALTER JOHN LLOYD of the firm of Lloyd Brothers of Harborne in the
County of Stafford, Manufacturers "IMPROVEMENTS IN TRICYCLES AND OTHER
VELOCIPEDES
"
My invention consists of the improvements hereinafter described in tricycles and
other velocipedes.
I will describe my improvements in connection with a tricycle
In order to facilitate the motion of the tricycle in a curve and to secure the
driving of both wheels when the tricycle moves in a straight line I adopt the
following arrangement of parts.
The travelling wheels are not fixed on the shaft but are capable of rotating
thereon. Near the hub of each of the travelling wheels, a chain wheel is fixed on
the shaft, the said chain wheel receiving motion from the crank shaft. The hub
of the chain wheel has two cylindrical holes parallel to the shaft, the said holes
extending from the outer face to nearly the inner face of the hub. Cylindrical
plugs shorter than the holes are placed in the said holes, a coiled spring at the
bottom of each hole forcing the plugs outwards. The outer ends of these plugs
bear against the hub of the travelling wheel. In the face of the travelling wheel
against which the plugs bear is a series of depressions suitable for the reception of
the ends of the plugs. These depressions are of a cylindrical figure on one side
but are inclined on the other side so that when the motion of the shaft is such
that the plugs bear against the cylindrical sides of the holes in the hubs of the
wheels, the said wheels are carried round with the shaft but when the motion of
the shaft is in the opposite direction the plugs slide up the inclined sides of the
holes in the hub of the travelling wheel and the said wheel, is not carried round by
the shaft. By this arrangement, both wheels are driven by the shaft when the
tricycle moves in a straight line but when moving in a curve the motion of the
shaft is communicated to one only of the travelling wheels, the other travelling
wheel moving at the rate required by the curve in which the tricycle is moving.
The arrangement described may be applied either to the shafts of the travelling
wheels or to the crank shaft
I construct the steering apparatus in the following manner
Instead of supporting the hind or steering wheel of the tricycle by means of a
vertical fork as usual, the head of which swivels in a bearing at the end of the
framing, I support the hind or steering wheel and construct the parts connected
with it in the following manner. Instead of using a small hind or steering wheel
I use a hind wheel preferably of the same diameter as the travelling wheels.
The said large hind wheel is furnished with a horizontal axle projecting some
distance on either side the wheel. The said axle is supported at its extreme ends
in curved bearing plates fixed to the rear ends of the framing of the tricycle
which framing is thus made considerably broader at its rear end than usual. The
concave faces of the said fixed bearing plates are turned to each other, the curve of
the said plates being struck from the middle of the axle of the large hind wheel.
The said concave bearing plates are slotted and in the slots sliding brasses or
bearing blocks work V shaped ribs on the upper and lower sides of the slotted
plates taking into V depressions in the bearing blocks. In these sliding bearing
blocks the ends of the axle of the hind wheel are supported and turn, spheres or
balls or cylindrical rods being interposed between the axle and the interior of

page_text: the bearing blocks to reduce friction. The said balls or rods are kept in their
places in the bearing blocks by means of a cap or cover screwed to the front of the
said block.
By moving the sliding bearing blocks simultaneously in opposite directions in
their slots in the fixed bearing plates, the desired inclination can be given to the
large hind or steering wheel for guiding or steering the tricycle.
The steering mechanism is constructed as follows
<-
To each of the caps or covers of the bearing blocks in which the ends of the axle
of the hind wheel work, a connecting rod is jointed. The inner ends of these
connecting rods are jointed to the ends of a horizontal lever turning on a centre
situated under the seat for the driver. To this lever the rod of the steering
handle is jointed near one end of the said lever. Or a steering handle at each side
of the tricycle may be connected to the lever described. By operating upon the
steering handle the lever is turned in one or other direction upon its centre. This
motion is transmitted through the connecting rods to the bearing blocks of the axle
of the hind wheel and a like motion is given to the said wheel so as to effect the
steering of the tricycle, the bearing blocks on the motion of the said lever sliding in
opposite directions in the slotted bearing plates as before described.
In order to obtain two different speeds I construct the chain wheels in the
following manner.
The chain wheel on one end of the crank shaft and that on the same end of the
travelling shaft are constructed as follows:-Each tooth of these wheels is provided
with a supplementary tooth on the side of the wheel, these supplementary teeth
are capable of being turned and fixed outwards, that is, from the centre, when they
constitute a toothed wheel of larger diameter than the normal wheel; or they may
be turned inwards when they are out of action and the normal wheel receives the
chain. The wheel on the travelling shaft is larger than that on the crank shaft.
When the normal wheel on the crank shaft is geared to the supplementary
wheel on the travelling shaft, the travelling shaft rotates at the same speed as the
crank shaft.
When the supplementary wheel on the crank shaft is geared to the normal
wheel on the travelling shaft the latter travels at a slower speed than the crank
shaft and with greater power
The supplementary teeth are raised when required by an arm against which they
are made to strike.
The teeth of the normal wheels engage with a less number of links of the chain
than those of the supplementary wheels.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents a plan; Figure 2 a side elevation and Figure 3 an end
elevation, of a tricycle containing driving and steering mechanisms constructed
according to my invention; Figures 4. 5. 6. 7. 8 and 9 represent separate parts and
details of the driving mechanism, which is applied to the crank shaft, drawn to a
larger scale, and Figures 10, 11 and 12 represent parts of the steering mechanism,
drawn to a larger scale.
The same letters of reference indicate the same parts in Figures 1 to 12.
I will first describe the driving mechanism by the use of which the motion of
the tricyle in a curve is facilitated and the said tricycle driven by both wheels
when moving in a straight line.
a, a are the travelling wheels turning loosely on their shafts or axles b, b carried
by the framing d of the tricycle; c is the hind or steering wheel made nearly of the
same diameter as the travelling wheels a, a.
Fixed on each of the loose travelling wheels a, a is a chain wheel e and on each
end of the crank shaft f is a similar chain wheel g over which chain wheels e and g,
the chain h passes by which the motion of the crank shaft is communicated to the
travelling wheel. The chain wheel g turns loosely on the end of the crank shaft f
and the inner face of the said chain wheel g is furnished with a series of step like

page_text: depressions, . These depressions are of a cylindrical figure on one side, but are
inclined on the other side, the bottom of the incline terminating in a step or
shoulder (see Figure 6).
Fixed on each end of the crank shaft is a boss or collar k
in which two cylindrical holes at opposite points are made. In these holes, plugs
or bolts, slide, coiled springs m at the bottom of the said holes forcing the plugs
or bolts outwards. The outer end of each plug or bolt is inclined and a key or
projection n working in a key way in the cylindrical hole prevents the bolt or
plug from rotating (see Figures 8 and 9).
The driving mechanism situated on the crank shaft is represented, drawn to a
larger scale, in end elevation in Figure 4; vertical section in Figure 5 and in section
taken through three of the depressions i, i in the boss of the chain wheel, in
Figure 6; Figure 7 represents a front elevation of the chain wheel g and exhibits
the position of the depressions in its boss; Figure 8 represents an end elevation
and side elevation of a portion of the crank shaft and Figure 9 represents one of
the sliding plugs or bolts and its spring.
By an examination of Figures 5 and 6 it will be seen that the bolts or plugs l, l
are pressed by the springs m against the inner face of the hub of the chain wheel g
and the inclined ends of the said bolts or plugs are made to engage with the steps
or shoulders of the depressions in the said chain wheel g when the cranked shaft is
moved in the direction indicated by the arrows in Figures 2. 4 and 7 so as to give
a forward motion to the tricycle the bolts or plugs, by their engagement with
the shoulders or steps of the chain wheel g, coupling the latter with the crank
shaft and the said shaft and chain wheel travel together at the same speed, the
same action taking place at both ends of the crank shaft. The motion of the chain
wheels g at the ends of the crank shaft is transmitted through the chains h, h and
chain wheels e, e to the travelling wheels a, a in the ordinary way. When the
crank shaft is turned in a contrary direction to that indicated by the arrow in
Figure 2 so as to give a backward motion to the tricycle, the spring plugs or
bolts, slide up the inclined sides of the depressions i, i in the face of the chain
wheels g and the said chain wheels are not carried round with the shaft.
By this construction of the parts, a double driver is provided, that is, both of the
travelling wheels a, a are driven from the crank shaft when the tricycle is moving
in a straight path, the said construction of parts also permitting the two travelling
wheels to have independent speeds when the tricycle is moving in a curve.
When
the tricycle is moving in a straight path, both travelling wheels a a are carried
round by the crank shaft at the same speed in consequence of the engagement of
the bolts or plugs, with the steps or shoulders of the depressions i, i in the chain
wheels g, g. When however the tricycle is moving in a curve that travelling wheel
which is describing the outer curve rotates at a quicker speed than the other
travelling wheel. The said increased speed of the outer travelling wheel being
communicated to the chain wheel g causes it to advance upon and push back the
bolts or plugs, carried by the crank shaft f thereby automatically ungearing
itself temporarily from the crank shaft, the other travelling wheel through its chain
wheels remaining locked to and travelling at the same speed as the crank shaft. As
the tricycle resumes its motion in a straight line, that travelling wheel which was
temporarily ungeared from the crank shaft is again geared to and travels at the
same speed as the crank shaft. Thus, while both travelling wheels are geared to and
driven by the crank shaft when the tricycle is travelling in a straight path yet the
gearing described permits one of the travelling wheels when the tricycle is moving
in a curve to automatically ungear itself from the crank shaft thereby permitting
it to move at a speed required by the curve in which the tricycle is moving, the
other travelling wheel remaining geared to and travelling at the same rate as the
crank shaft.
The double driver hereinbefore described may be applied to the shafts of the
travelling wheels instead of to the crank shaft as described and illustrated. In
this case, the positions of the chain wheels e and g are reversed that is, the chain
wheel g and the spring bolts ., are situated respectively on the hub of the

page_text: travelling wheel and its shaft, and the chain wheel e is situated on the crank
shaft.
I will now describe the steering mechanism constructed according to my
invention.
The bind or steering wheel c is made preferably nearly of the same diameter as
the travelling wheels a, a and is fixed to the horizontal axle c which projects some
distance on each side of the said steering wheel. The ends of the axle c³ are
supported and turn in the brasses or bearing blocks p, p the said brasses or bearing
blocks being supported by and made capable of sliding in the curved bearing
plates q, q bolted together by end bolts, as represented, fixed to the rear ends of the
framing d of the tricycle. The steering mechanism is best seen in the enlarged
views Figures 10. 11 and 12 of the drawings. The curved bearing plates q, q are
slotted or open at the sides and the brasses p, p work in the slots or open sides,
V shaped ribs on the upper and lower inner faces of the said bearing plates taking
into V depressions in the brasses or bearing blocks p, p (see the section Figure 11).
In order to reduce friction spheres or balls or rollers may be interposed between
the axle c² and the interior of the brasses or bearing blocks p. p. The sliding
bearing blocks p, p are moved simultaneously in opposite directions for giving the
desired inclination to the steering wheel c by the following combination of parts:-
To each of the bearing blocks p a connecting rod r is jointed. These connecting
rods r, proceed to the middle of the tricycle and are jointed to opposite ends of
the lever 8 turning on the centre 82 (see the plan Figure 1 and end elevation
Figure 3); t is the steering rod jointed at t² to one end of the lever 8; u is the
steering handle provided with a pinion as usual, which gears with the racked end
of the steering rod t. By turning the steering handle in one or other direction the
lever 8 is moved in one or other direction and by means of the connecting rods r, r
jointed to the bearing blocks p, p a like motion is transmitted to the hind or steering
wheel c and the required inclination given to it for guiding or steering the tricycle.
In Figure 12 the steering wheel and parts connected to it are represented in the
positions they occupy when the tricycle is travelling in a straight path and the said
parts are also indicated in the positions they occupy when the steering wheel is
inclined in one directon for steering the tricycle. By an examination of the said
Figure 12 it will be seen that when the sliding brasses pp are operated upon by
the steering handle through the rod t, levers and rods r, r, the said brasses slide in
opposite directions in the slotted bearing plates q, q so as to give the desired
inclination to the steering wheel.
A handle and steering rod situated at each side of the machine may be connected
to the lever & for working the steering mechanism.

I will now describe the chain wheels constructed according to my invention for
obtaining two different speeds at the will of the rider.
Figures 13 and 14 represent side elevations of the chain wheels situated on the
end of the crank shaft and shaft of the travelling wheel of the tricycle and
Figure 15 represents an edge view of Figure 14; Figure 16 represents the inner
side of one of the chain wheels and exhibits the arrangement of the springs for
maintaining the supplementary teeth of the chain wheels in their open and closed
positions respectively.
The same letters of reference indicate the same parts in Figures 13. 14. 15
and 16.
a is the chain wheel situated on the shaft of the travelling wheel and b is the
chain wheel situated on the crank shaft; c is the chain passing over the two chain
wheels; d d are the supplementary teeth of the chain wheels turning on the
centres d², d the said teeth d, d moving on their centres in different directions in
the two wheels. By means of the centres of the teeth d, d they are capable of
being either turned inwards or outwards. When the supplementary teeth d are
turned outwards as in the wheel 6 Figure 13 and the wheel a Figure 14, they
constitute a toothed wheel of larger diameter than the normal wheel the said
supplementary teeth now receiving the chain c; and when the supplementary teeth a

page_text: are closed or turned down upon the normal wheel they are out of action as seen in
the wheel a Figure 13 and the wheel b Figure 14, and the teeth of the normal
wheel now receive the chain c. The supplementary teeth & are maintained in their
closed and open positions respectively by means of the coiled springs e, e as seen in
Figure 16, where one of the teeth d is represented turned down and the others
turned outwards. When the teeth d are turned outwards the pressure of the
springs e is on one side of the centres of the teeth and when turned down the
pressure of the springs e is on the other side of the centres of the teeth, hence the
said teeth are preserved in their open and closed positions respectively.
When the teeth d, d of the two chain wheels a, b are arranged as in Figure 13,
the said wheels are of the same diameter and the tricycle is made to rotate at the
same speed as the crank shaft. When the two wheels a, b are arranged as in
Figure 14 the wheel a is made of larger diameter than the wheel b by the turning
outwards of the teeth d, d of the said wheel a, and the turning inwards of the
teeth dd of the wheel b. The chain wheel a on the travelling wheel of the
tricycle now rotates at a slower speed than the chain wheel b on the crank shaft
and the tricycle is consequently driven with greater power.
On each of the supplementary teeth d is a stud f for the purpose herein after
explained.
The supplementary teeth d, d are raised in the wheel a and simultaneously
closed in the wheel b, or the reverse, by means of the arm or lever g and parts
carried by it, the said lever g moving on the centre g² in a plane at right angles to
the plane of the chain wheels a, b. One arm of the lever g carries at its end a
jointed pawl h against which the studs f. f on the teeth d, d strike for opening the
teeth of the wheel a. The same end of the lever g also carries a short arm i for
closing the teeth d, d of the wheel a by the striking of the point ends of the teeth
against the said arm i. The said arm i and pawl h are situated in different planes
(see the end elevation Figure 15). The other or lower arm of the lever g carries
at its end a jointed pawl k. For opening the supplementary teeth d d of the wheel b
by the striking of the studs f, f against the said pawl k and on the same end of
the lever g is a short arm for closing the teeth d, d of the wheel b by the
striking of the point ends of the said teeth against the said arm l. The lever
moved in one or other direction through a small angle upon the centre g² by means
of a handle on the rod m within reach of the rider.
is
When the lever g is moved into one position, the pawl k at one end of the lever
is brought into action and the short arm i at the other end of the lever is brought
into action (see Figure 15) and when the lever g is moved into the other position,
the pawl and arm i are taken out of action and the pawl h and arm l are
brought into action.
and
When it is desired to convert the chain wheels a, b Figure 13, into the chain
wheels a, b Figure 14, the lever g is so moved on its centre that the pawl h on the
upper end of the said lever g is brought into action and the short arm on the
lower end of the lever is also brought into action. As the chain wheel a rotates
the studs f, f on the teeth d, d strike against the pawl h and the said teeth are
opened out as represented in Figure 14; and simultaneously the point ends of the
teeth d, d of the chain wheel b strike against the short arm of the lever
the said teeth are closed as represented in Figure 14. The reverse action takes
place, so as to open the teeth d of the wheel b and close the teeth d of the wheel a,
when the lever g is moved so as to bring the pawl k and the short arm i into
action. The jointed pawls hk permit the teeth d to pass them without obstruction
and the point ends of the teeth d escape the arms i, i when a back motion is given
to the tricycle.
The improvements herein before described and illustrated in the accompanying
Drawings may be applied to velocipedes having more than three wheels.
