CERTAIN IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENTS OF PARTS
OF VELOCIPEDES APPLICABLE TO OTHER ANALOGOUS PURPOSES"
The improvements forming the Subject of this my said Invention_consist
principally in the construction, combination, or arrangement of parts herein after
described of velocipedes.
I will describe my Invention thus as applied to a Tricycle, my chief object being
to provide means whereby the rider may utilise the power for driving, with freedom
diminishing the vibration, with one form of Tricycle it may be ridden in one track
as a bicycle by another form, two or the necessary parts may be united for two
riders.
The frame of the Tricycle or Bicycle is built horizontally, from a suitable part of
the frame I arrange one or a pair of spring supports for carrying the saddle from
the latter and in the required position I arrange the steering bar and handle
support the latter being fitted to the spring supports on the principle of the Ball
and Socket having an internal slide or with the latter only at the bottom of the
steering rod is a universal joint, and below this a pinion, immediately under the
said socket joint is a spiral spring which by means of a screw arrangement is
capable of adjustment to suit the weight of the rider. The handle bar is curved
back and downwards and can be fitted with two pair of handles when required.
To effect the steering, I pass a rod or rods with racks at each end, being
actuated by the pinion on the bottom of the steering bar or by suitable double or
single levers and so give the desired motion to the steering wheel or wheels..

page_text: In the case of folding Tricycles viz:-Tricycles so constructed as to be diminished
in width, so as to pass an ordinary door way I place one or more joints constructed
as hereinafter described under the steering bar pinion levers or lever, so that the
rack moves round the pinion, in the case of one rear steering Tricycle I place on
both ends of a stay or stretcher bar points so that when the stay is moved the
said points press against springs which are attached by means of pegs to the racks,
and so releive the pinions allowing the wheels to close together sufficient for the
purpose above described, the racks are again freed, and the tricycle may be ridden
in one track as a Bicycle, and further by omitting, or removing, the joint and one
wheel and placing the steering rear wheel closer to the driver, a Bicycle is thus
formed.
The driving wheel is actuated by treadle bars extending to the periphery of the
wheel where they are connected with the frame the crank being driven by a
connecting rod which is capable of being shortened or lengthened by means of
screws, for the purpose above set forth, where these connecting rods join the treadle
bars, I connect a double ended latch provided with a spring so that they. viz.
connecting rods may be moved forward when required, increasing the leverage and
ascending hills &c with greater facility.
To attain greater power, an extra joint is inserted in the treadle lever nearer
the point of connection, the said joint to be freed by raising the locking bar and
attaching it to the frame by a suitable scrow, or the fulcrum may be fixed in a
similar position instead of the treadle bar being extented to the periphery of the
wheel.
Instead of the crank I use a driving action without dead centros, and employ a
well known wedge and roller arrangement and to recover the stroke I pass the
connecting cord or chain through the tubular framing and over the necessary pulley
or pulleys and connect the treadles and one driving connection with another, I
pass one connection through the other one or both being tubular, or continue the
treadle bars round and connected at the back and crank each at that point where
it is necessary for them to cross each other. To check the stroke I joint to the
frame near the point where the connecting strap leaves the driving drums a
hanging piece with a hole and socket; into the latter the upper end of the stiff
part of the connection fits and a top stop on the flexible part, With an open
fronted frame, I construct that portion of the frame between the two sides of
three or more tubular parts together telescopically, so as to reduce the width the
fixing apart being effected by a double screw or fly-nut, and when for two or more
riders, so that either rider may steer, I employ two or more handles, having
pinions attached which actuate double sided rack or racks on the steering rod.
To provide a perfect brake for these vehicles, I place a suitable fork either from
the front part of the frame or a specially formed extension of another pattern
frame, and by working a rod presses the ground acting conjointly as a brake; and
when applied to Bicycles as a stand or support.
I construct the tyres of coils or helixes of wire steel by preference through which
passes bands or wires suitably shaped, the ends of which are screwed together this
tyre is then placed in a crescent shaped felloe provided with a screw arrangement
so as to expand it and lock all securely together.
When I use India-rubber or similar material for tyres I prefer to secure them as
follows, to the felloe, which I then construct of one or more parts, one of which is
serrated at the edges and the points thereof are inserted into the tyre by a machine
or tools, the tyre being first pressed down at the sides the points are then inserted
and the whole rolled or pressed so as to extend the points which then hold the
type Secondly. The spokes are then passed through the type. This arrangement
of serrated attachments is applicable to other purposes of mechanically connecting
similar or dissimilar substances together If an outer casing is used to the type
which then is preferably of textile material it is not neccessary to serrate the
felloe, only to pass the spokes through the whole, the heads of the spokes then
being nearly as deep as the outer casing

to a base plate and covered with a water proof or other suitable covering and to
prevent the saddle from becoming wet by rain. I provide a double texture cover,
which is secreted inside the saddle, being pulled in by a coiled spring exposing
only a button which is employed to draw out the said cover when required

"CERTAIN IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENTS OF PARTS
OF VELOCIPEDES, APPLICABLE TO OTHER ANALOGOUS PURPOSES."
"
The improvements forming the subject of this my said Invention consists
principally in the construction, combination, or arrangement of parts hereinafter
described of velocipedes.
I will describe my Invention thus as applied to a Tricycle, my chief object being
to provide means whereby the rider may utilise the power for driving, with
freedom, diminishing the vibration to a minimum With one form of Tricycle it
may be ridden in one track-as a Bicycle, by another form two; or the necessary
parts may be united for two riders.
The frame of the Tricycle or Bicycle is built horizontally; from a suitable part
of the frame I arrange one or more pair of spring supports for carrying the saddle,
from the latter, and in the required position I arrange the steering bar, and handle
support; the latter being fitted to the spring supports on the principle of the Ball
and Socket baving an internal slide, or with the latter only; at the bottom of the
steering rod is a universal joint, and blow [sic] this a pinion, and immediately under
the said socket joint is a spiral spring which by means of a screw arrangement is
capable of adjustment to suit the weight of the rider. The handle bar is curved
back and downwards, and can be fitted with two pairs of handles when required.
To effect the steering, I pass a rod or rods with racks at each end, being actuated
by the pinion on the bottom of the steering bar, or by suitable double or single
levers, and so give the desired motion to the steering wheel or wheels-In the case
of folding tricycles, viz; Tricycles so constructed as to be diminished in width, so
as to pass an ordinary door way-I place one or more joints; constructed as herein-
after described. Under the steering bar pinion lever or levers are situated; so that
the rack moves the pinion round-In the case of one rear steering tricycle I place
on both ends of a stay or stretcher bar joints; so that when the stay is moved, the
said points press against springs which are attached by means of pegs to the racks;
and so relieve the pinions, allowing the wheels to close together sufficient for the
purpose above described, the racks are again fixed, and the tricycle may be ridden
in one track as a Bicycle, and further by omitting or removing the joint and one
wheel and placing the steering rear wheel closer to the driver a bicyclo is thus
formed.
The driving wheel is actuated by treadle bars extending to the periphery of the
wheel where they are connected with the frame, the crank being driven by a
connecting rod, which is capable of being shortened or lengthened by means of
screws; for the purpose above set forth, where these connecting rods join the
treadle bar, I connect a double ended latch provided with a spring, so that they
vis; the connecting rods, may be moved forward when required, increasing the
leverage, and ascending hills & with greater facility. Instead of the crank I use a
driving action without dead centres, and I employ a well known wedge and roller
arrangement, and to recover the stroke I pass the connecting cord or chain through
the tubular framing, and over the necessary pulley or pulleys and connect the
treadles and one driving connection with another. I also pass one connection
through the other, one or both being tubular, or I continue the treadle bars around,
and connected at the back, and crank each at that point where it is necessary for

page_text: them to cross each other. To check the stroke I joint to the frame near the point
where the connecting strap leaves the driving drums, a hanging piece, with a hole
or socket; into the latter the upper end of the stiff part of the connection fits, and
also a top stop on the flexible part. And I also employ two or more handles,
having pinions attached, which actuate a double sided rack or racks on the
steering rod.
To provide a perfect brake for these vehicles I place a suitable fork either from
the front part of the frame, or a specially formed extension of another pattern
frame, and by working a rod presses the ground acting conjointly as a brake, and
when applied to bicycles as a stand or support.
I construct the tyres of coils or helixes of wire steel by preference through
which passes bands or wires suitably shaped, the ends of which are screwed
together this tyre is then placed in a crescent shaped felloe provided with a screw
arrangement so as to expand it and lock all securely together
When I use India-rubber or similar material for tyres I prefer to secure them as
follows to the felloe, which then construct of one or more parts, one of which is
serrated at the edges and the points thereof are inserted into the tyre by a machine
or tools, the tyre being first pressed down at the sides the points are then inserted
and the whole rolled or pressed so as to extend the points which then hold the
tyre securely-The spokes are then passed through the tyre--This arrangement of
serrated attachments is applicable to other purposes of mechanically connecting
similar or dissimilar substances together; if an outer casing is used to the tyre
which then is preferably of textile material it is not necessary to serrate the felloe,
only to pass the spokes through the whole, the heads of the spokes then being
nearly as deep as the outer casing. I construct the saddle of strips of spring metal
steel by preference connected to a bare plate, and covered with a water proof or
other suitable covering and to prevent the saddle from becoming wet by rain-I
provide a double texterre cover, which is secreted inside the saddle being pulled in
by a coiled spring exposing only a button which is employed to draw out the said
cover when required.
I construct the pedals from sheet metal by stamping and of any desired shape or
configuration if double sided are required then I employ two similar pieces, and to
prevent vibration to the rider I arrange upon or between the pedal and treadle bar
a spiral spring.
The steering-head I construct with a neck having two projecting bearings, into
which fits a double coned spindle, and to this a pinion, lever or socket for handle
bar according to the position it is used, the socket for handle bar being used for
Bicycles of the ordinary form
I construct roller bearings (antifrictional) being a series of hardened metal
rollers strongly mounted in two rings, which are framed together by a suitable
number of bars passing through the necessary number of the rollers, between these
said rollers are an equal number of smaller rollers, which keep the principal rollers
from bearing upon or against each other-These bearings are applicable to all
revolving wheels, spindles, axles and shaftings
In Bicycles constructed with horizontal frames as before described-I arrange
that part of the handle bar over the spindle to be mounted in a rigid frame, the
supports coming near the centre of the wheel. The brake to be actuated in a
similar manner to the steering consisting of a band arranged in the interior of the
hub. I make the throw of the crank or fixing of pedal pin easily adjusted. I
construct the pedal or connecting rod pin with a head and pass it through the slot
in crank, from that side nearest the wheel, the crank is recessed in the required
number (generally three) of places to receive the said head of pin, nut or washer,
which pin is tightened up by a nut or nuts next the crank, or at the outer end by
inserting an intermediate sleeve, and in some forms of Tricycles I add an extra
break with a curved central support.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my Invention may be performed

page_text: Figure 1. represents a plan of a Tricycle containing the principal parts of the
machine, constructed according to my invention-Figure 2 represents a side eleva-
tion of the same machine, and figures 3. 4. 5. 6. and 7. shows parts and modifications
of the same as hereinafter described-The same letters of reference indicate the
same parts in the last named figures
a, a, is the horizontal framing of the machine extended frontwise beyond the
periphery of the driving-wheel, b., b., are the treadles jointed to the prolonged
front framing, c. is the spring support attached at one end to the horizontal framing
described while at the other or free end, the seat of the rider is situated as shown
at d, the saddle end of the spring support is connected to a ball and socket joint
arrangement c² for the purpose of determining the proper position, and the
necessary play to the handles e, e of the machine on the spring support being more
or less flattened or compressed by the weight of the rider-The said spring support
rests upon a coiled spring enclosed within the hollow case f. The steering rod or
spindle g is jointed near it's bottom to a universal joint and below the said joint a
toothed wheel h is situated, which engages with the rack teeth on the rack bars i. i.
passing through the hollow framing . . of the steering wheels ; The teeth ³. of
the rack bar i communicates the motion imparted to it, from the bar handle to the
pinions, attached to the respective steering wheels- is the stretcher bar for
giving rigidity and detaining the collapsable frame, carrying the steering wheels in
its open or closed positions
The action of the parts of the machine to which my improvements have
reference, is as follows-By the arrangement represented of the spring support c
and it's connection with the hollow case f, the seat being suspended as shown and
represented, great elasticity and ease is imparted to the seat and the reduction of
tremor is reduced to a minimum
The handle bar in consequence of being connected to the ball and socket joint, is
capable of accommodating itself, with respect to the spring support to the desired
position, for the rider of the machine to operate and control the steering bar
The double steering is effected by partially rotating the handle bar, the pinion h.
on the bottom of the steering bar g. takes into the teeth of the racks i, i, when by
the motion of the said pinion, the racks are made to slide within the hollow frame
of the steering wheels, motion being communicated to the pinious h³. h². and
thereby imparting the requisite angular motion to the steering wheels to which the
steering pinions h³. h. are attached
The stretcher bar ke gives rigidity and retains the jointed frame opened or closed
according to whether the said Tricycle is being used (practically) as a single or as
a three track machine-In figure 1. the frame is shown open, with the stretcher
bar in its proper relative position-and when the machine is required to be
collapsed, so as to bring the wheels into juxta position, or side by side, the stretcher
bar lock nut has to be released, the joint marked m is hereinafter described and is
shown on sheet 3
When it is desired to convert the Tricycle figure 1 into a Bicycle, the collapsable
frame is removed, and the parts figure 7. substituted therefor
Figure 3 shows the steering parts of the Tricycle on a larger scale, while figure 4
represents a transverse section of the same, with the freeing mechanism applied-
In figure 5. the rack is shown taken out of gear with the pinion by the stud point
working within the slot in the rack bar
The Action of the Stud point is to throw the rack or racks out of gear, with the
pinion, for the purpose of closing or collapsing the Tricycle; in this case the
stretcher bar, is attached immediately above the pinion, instead as shewn at
Figure 1.
Figure 6 shows the stretcher bar lock joint on a larger scale, the said joint is
opened or freed by the internal spring washer-Figure 64 shews the connection of
the handle bar with the steering bar and spring supports, the said figure also shows
the screw adjustment for regulating the tension of the spring to the weight of the
rider.

page_text: Figure 8 is a modification of the Tricycle described, and consists of a rigid frame
with double lever steering attached the said frame constitutes a girder frame 1, I is
the upper portion and 12, 12 is the lower, l' is a rigid support with the steering bar
inside, Figure, 9 shows a side view of Figure 8-Figure 10 is a modifiation of a
Tricycle frame Figure 1 with the wheels disposed longitudinally, instead of laterally
as in figure 1. in this form of frame it is not necessary to employ either the ball
and socket, or the universal joint for the steering
To form a double velocipede (for carrying two persons) two single machines are
arranged as shown at figure 10, one of them has a driving wheel on the reverse
side in order to form a pair, that is, when placed together, the driving wheels come
in contact centrally and are connected by means of a jointed plug, which fits into
the respective hubs and is kept in position by suitable Cotters, or a second portion
without the driving wheel may be added, the two rear steering wheels are
connected by a rod to a pair of levers, projecting rearwards. Or the machine may
be as shewn in figures 11, 12, and 13, that is with one of the Steering wheels
placed immediately behind the driving wheel, so that only one extra small steering
wheel with the necessary attachments and seat are required. In this form to
provide for the inequalities of the road, the spring supports are connected between
the axle bearings and the frame. The part for the second rider is attached or
detached by means of a plug, fitting into the hub as before described, also by a
screw and nut over the rear wheel. The machine is steered by three small wheels
either as shown in figure 11 or as shown in figure of the drawings Figure 12 is
a side elevation and Figure 13 is an end elevation of Figure 11., showing the
rotary action as hereinafter described.
Figures 14, 15 and 16 represent modifications of the adjustable spiral spring for
supporting the seats or saddles of tricycles other than that represented in Figure 1.-
n is the spiral spring for supporting the seat, p is the spindle the lower end of
which works in the loose screw box p². the upper end of the spindle described, is
provided with the ball and socket arrangement pe fitting to the base plate carrying
the seat, p³. is the slide box, in which the loose screw moves p' is the connecting
plate for its attachment to the tricycle frame. The Spring support 9 is place
within the spiral spring and continued to the peak of the saddle. In figure 16 the
spiral spring is enclosed within the frame, the bottom portion of which has two
extended screw parts, while the upper part is provided with' eyes or holes for
receiving the screws on the lower part, and being regulated by nuts. The saddle is
connected by a neck o' the base of which is attached and is supported by the spiral
spring. Figures 17 and 18 shows another method of attaching the handle bar and
steering mechanism made according to my invention. Figures 19 and 20 represents
a double ended compound latch as applied to extending pedals for the purpose of
increasing the power of velocipedes to which they are or may be applied; is the
part bearing the pedal which slides into the treadle bar v; v³ is the acting end of
the latch, kept in position by springs v; v³ is one end of the latch for freeing the
pedal for drawing out; v is the end for closing. Figure 21 shows the arrangeinent
of the cord or chain for passing through the tubular frame for recovering the
stroke after each movement of treadle. Figure 22 represents an arrangement by
which a continuous action is attained, instead of alternate as in the case of figure 21,
each treadle traverses a complete circuit from side to side. At the front, the
connection of one treadle bar passes through the other one, and at the back, where
the two bars cross each other is cranked to enable the required movement to be
made; by the above means there are two treadle bars on each side of the machine;
so that, a doublo action is attained on both sides
Figure 23 shows the arrangement for checking the stroke of the treadle as used
with the known wedge and roller arrangements as used with figures 21 and 22.
Figures 24 and 25 represents a ground brake constructed and arranged according to
my invention applied to an ordinary bicycle-Figures 26, 27, 28, 29 30 and 31°
shows the various forms of tyres and means of attaching tyres to their felloes
constructed according to my invention; the wheels constructed according to

page_text: figures 26 and 27 reduce tremor or vibration to the vehicle, to which they are
applied.
The said wheel is built up of two bands and a tyre as represented; the tyre
is either a hollow one of coiled wires, (for instance) or connected by means of
bolts for the purpose of keeping the tyre and inner band separate. The inner band
being free to move up the spokes, the desired distance. Figures 32, 33 and 34
represents a saddle constructed according to my invention; the saddle consists
essentially of a series of springs of the configuration represented in figure 34-The
peak of the saddle figure 32 is moveable or is capable of being lengthened or
shortened accordingly as the rider of the saddle may require. Figures 35 and 36
show the saddle cover applied to a saddle, which is drawn inside the saddle, either
by an involute spring or by a cord attachment.
Figure 37 represents a double sided pedal; figure 38 a single pedal and figure 39
an enlarged section of the double pedal connection applied with a spiral spring or
springs for reducing vibration.

the application of rubber bars thereto; also showing the means of attaching the
said rubber and pedal plates together
Figure 43 shows the steering head constructed according to my invention for
tricycles and figure 44 shows its application to bicycles of the ordinary form-The
said figures consists essentially of a neck, with two conical bearings, into which
fits a double coned spindle, and to this spindle is attached a pinion, lever or socket,
for the handle bar; in the latter case adjustably-Figure 45 and 46 show an end
elevation and section of roller bearings, constructed according to my invention, as
before described, in the introductory part of the specification-Figures 47 and 48
show a bicycle constructed according to my invention in which one handle of the
machine actuates the brake while the other handles operates the steering rod―
Figure 49 is an enlarged view and section of the mechanisın employed in the
application of the brake, and effecting the steering thereof, As the two bars for
imparting motion to the steering wheel and brake are alike, we will only describe
one of them-The bar & also serves both for the purpose of support and movement
as described; the upper portion being square fitting into the socket 83, which the
handle bar is attached; ³ is the spiral spring, 8 is the connecting bracket with
socket at each end, through which 82 passes, and to which the upper end or ends of
the saddle spring support is attached-Figure 50 shows a front elevation, and
figure 51 a transverse vertical section of the brake arranged in the interior of the
hub; which consists essentially of a recess or cavity in the hub, and an internal
strap or band, which is actuated by a double compound lever wedge or suitable
extending device.
Figures 52, 53 and 54 represent the means or method of adjusting the pedal pin
and parts connected with it, to the the crank.
