PROVISIONAL SPECIFICATION.
Improvements in Mechanism to Increase or Multiply Speed to be
used for Cycles and other Contrivances.
JOSEPH BECKER 42 Alma Square St. Johns Wood County of London do
hereby declare the nature of this invention to be as follows :-
Improvements in mechanism to increase or multiply speed to the used for cycles
and other contrivances.
My improvements to increase or multiply speed consists in constructing gears
which are of various kinds, and fitted to cycles and other contrivances in
various ways.
For instance to increase the speed of a safety cycle the bottom bracket is
formed in various ways either as a hollow or as an elbow-shaped cylinder, or fitted
with a cylinder, or the bracket may be formed or fitted with a fork or other
bracket used to receive the spindle and the driving wheel.
The bottom bracket has one or more partitions which are either fitted or are
part of it, and which divide the bottom bracket into compartments.
The ends of the bottom bracket are formed in various ways and are closed but
can be unfastened to admit the fittings of the spindle. Holes are made in the ends
and partitions to receive the spindle or pin.
When using two compartments, a mitre wheel which I term stationary mitre
wheel is placed loosely on the spindle in the first compartment and attached at the
inside at one end of the bottom bracket.
Opposite the stationary mitre wheel a mitre wheel with a neck called a revolving
mitre wheel is fitted to the spindle the neck passing through the partition into the
second compartment.
One or two travelling mitre wheels are fitted to the stationary and revolving
mitre wheel which may be covered with a form. Holes are made in the form and
travelling mitres through which a pin or pins passes fastening them to the spindle
in various ways.
In the second compartment a stationary mitre wheel is placed loosely over the
neck of the revolving mitre wheel and fastened to the partition. Opposite this
stationary mitre another mitre wheel with a neck is fitted to the spindle termed
driving mitre wheel. The neck of the driving mitre passes through the end of
the bottom bracket outside and the driving wheel is attached to it. The driving
wheel may also be placed inside the bracket.
One or two travelling mitres are fitted to the driving and stationary mitre, which
may be covered with a form.
Holes are made in the form, travelling mitres and neck of the revolving mitre,
and form and travelling mitres are fastened by pins to the neck of the revolving
mitre.
The revolving mitres, spindle or other parts are fitted when required with
accessories for reducing friction, as ball-bearings, rollers, etc.
The cranks are fitted to the spindle and when turned the travelling mitres in
the first compartments turn the revolving mitre wheel and the neck of same turns
the travelling mitres in the second compartment, which turn the driving mitre on
whose neck the driving wheel is fitted causing same to revolve, so that one
revolution of the crank causes four revolutions of the driving wheel.
When bracket and fork are used partitions are made in same, the partition and
spindle are fitted similar to as described in the bottom bracket.
Another way to increase speed is to construct and fit the hub of the back wheel
in various ways.

page_text: The hub of the back wheel is formed as a hollow cylinder. It may be closed at
one end, and in the middle or other parts in the inside one or more partitions are
made forming compartments and are fastened to the hub or are part of same.
Holes are made in the ends of the hub and partitions to receive the spindle or
pin. Mitre or other wheels of various kinds are fitted to the spindle. In the first
compartment where the hub is open a stationary mitre wheel is fitted to the spindle
facing the inside and fastened to the spindle.
Another mitre wheel with a neck called a revolving mitre wheel is fitted loosely
to the spindle facing the stationary mitre, the neck passing through the partition
into the second compartment.
One or two travelling mitres are fitted to the stationary mitre and revolving
mitre wheel in the first compartment and are covered with a form which projects
outside the hub.
Holes are made in the form and travelling mitres used to fasten the form and
travelling mitres with one or more pins to the spindle.
The projecting cover form is cogged, grooved, or has holes made in it as
described in Patent No. 9,288 A.D. 1890 for improvements in driving bands and
alike and in wheels therefore.
In some cases the projecting cover form may be made as a bevel or other
wheel.
The projecting cover is used to connect the back wheel with the driving wheel.
In the second compartment of the hub a stationary mitre wheel is fitted loosely to
the neck of the revolving mitre and fastened to the partition. Opposite this
stationary mitre wheel another stationary mitre is fitted and attached to the
spindle. One or two travelling mitre wheels are fitted to the stationary mitres.
The travelling mitres may be covered with a form, holes are made in the form and
mitres and in the neck of the revolving mitre used to fasten the form and travelling
mitres to the neck of the revolving mitre wheel by pins.
The projecting cover form in the hub is connected with the driving wheel, and
when the driving wheel is turned the projecting cover form turns the travelling
mitres in the first compartment, which turn the revolving mitre wheel, and the
neck of same drives the travelling mitres in the second compartment which turn
the stationary mitre which is attached to the partition, hub, and wheel, so that
when the driving wheel revolves once the back wheel turns four times.
Another improvement to increase or multiply speed, can be obtained by
connecting the driving wheel to the back wheel by a rod or hollow cylinder, or
spindle sleeve and wheels which are of various kinds and used in various ways.
Partitions are made along the rod forming compartments. The partitions are
attached to a cylindrical cover form or bars, and the cylindrical cover form or bars
are attached in various ways to the bottom bracket, or fork, or bracket or frame,
and to the spindle at the back wheel or frame.
A bevel wheel with a neck is fitted loosely to the rod in the first compartment
engaging with the driving wheel.
The neck of the bevel wheel passes through the first partition into the second
compartment.
A stationary mitre wheel is fitted loosely over the neck and fastened to the
partition or may be part of it.
Opposite the stationary mitre a revolving mitre wheel with a neck is loosely
fitted to the rod, the neck passes through the partition into the third compartment.
One or two travelling mitres are fitted to the stationary and revolving mitre
wheel.
The travelling mitres may be covered with a form, holes are made in the form,
travelling mitres, and in the neck of the revolving mitre, used to attach same
together by pins.
The third or other compartments are all fitted in a similar way as described and
in the last compartment the revolving mitre wheel has a sleeve fitting loosely to
the rod.

page_text: At the end of the sleeve a mitre or bevel wheel is fitted which engages with
either the projecting form or bevel wheel on the hub according to which is used.
The sleeve and wheels may also be in one piece.
When the driving wheel is turned the bevel wheel in the first compartment
revolves, the neck of the latter turns the travelling mitres in the second compart-
ment, which turn the revolving mitre wheel, whose neck drives the travelling
mitres in the third compartment, which turns the revolving mitre, sleeve, and the
bevel wheel at the end of sleeve, which drives the bevel wheel on the hub or when
using the second improvement drives the projecting form on the hub.
When three partitions are used on the rod, by turning the driving wheel once
the back wheel revolves four times.
The hub of the front wheel of the ordinary bicycle is fitted similar to the back
wheel of the safety cycle.
The hub is formed or fitted as a hollow cylinder, one or more partitions being
made in the inside of it or are part of same.
Holes are made in the ends of the cylinder and through the partition to receive
the spindle or pin.
The ends of the cylinder can be unfastened to admit the fittings of the spindle.
When two compartments are made in the hub the spindle and hub are fitted as
follows.
A stationary mitre wheel with a neck is fitted loosely to the spindle in the first
compartment, the neck passing through the end of the hub outside and is attached
to one part of the fork.
Opposite the stationary mitre a revolving mitre wheel with a neck is loosely fitted
to the spindle the neck passing through the partition in the second compartment.
One or two travelling mitres are fitted to the stationary and revolving mitre
wheel.
The travelling mitres may be covered with a form. Holes are made in the form
and travelling mitres and used to attach same by one or more pins to the spindle in
various ways.
Another stationary mitre wheel is loosely fitted over the neck of the revolving
mitre wheel in the second compartment and fastened to the partition or is part of
same.
Opposite the stationary mitre wheel another mitre wheel with a neck is loosely
fitted to the spindle the neck passing through the other end of the hub outside, and
is attached to the other part of the fork.
One or two travelling mitres are fitted to the mitres; holes are made in the
form, travelling mitres and in the neck of the revolving mitre wheel, used to fit
same together by pins. When the cranks and other parts are fitted to the spindle
and turned the travelling mitre wheel in the first compartment revolves and turns
the revolving mitre wheel, whose neck revolves the travelling mitres in the second
compartment, which turns the stationary mitre wheel at the partition hub and
wheel.
Therefore one revolution of the cranks causes four revolutious of the wheel.
Tricycles and quadricycles are improved in a similar way as previously
described.
To the axle of a tricycle or quadricycle one or more partitions are made, the
partitions fitting loosely over the axle and being attached to the frame in various
ways or are part of same.
A stationary mitre wheel is fitted loosely over the axle and attached to the
partition or is part of same.
Opposite this stationary mitre a revolving mitre wheel with a neck is loosely
fitted to the axle, the neck passing through the second partition into the second
compartment.
One or two travelling mitre wheels are fitted to the stationary and revolving mitre
wheel in the first compartment.
The travelling mitres are covered with a form which may be cogged, grooved,

page_text: have holes made in it, or formed as a bevel or other wheel, and it is attached
to the travelling mitres as previously described and used for connection with the
driving wheel.
A stationary mitre wheel is loosely fitted over the neck of the revolving mitre
wheel in the second compartment and attached to the partition.
Opposite this stationary mitre a mitre wheel is fitted to the axle and attached to
it; one or two travelling mitre wheels are fitted to the mitres which may be covered
with a form. Holes are made in the form, travelling mitre wheels and in the neck
of the revolving mitre wheel, which are used for attaching them together by pins.
The wheels of the tricycle itself are fitted on the ends of the axle and fastened
to it.
When the form in the first compartment is connected with the driving wheel by
chains or other methods the travelling mitres in the first compartment turn the
revolving mitre wheel, whose neck drives the travelling mitres in the second com-
partment, which turn the mitre wheel attached to the axle causing the axle and
wheels at the end to revolve.
Thus when the driving wheel revolves once the wheels of the tricycle revolve
four times.
A sleeve can also be loosely fitted to the axle, the sleeve passing through the
partition. A stationary mitre wheel is fitted loosely over the sleeve and fastened
to the partition.
Opposite this stationary mitre a mitre wheel is fitted to the sleeve and attached
to it.
One or two travelling mitres are fitted to the mitre wheels which are covered
with a form, used for connection with the driving wheel, and constructed as
previously described.
Each end of the axle is fitted with a mitre wheel, the mitre facing inwards..
The side wheels of the tricycle are fitted similar to the back wheel of a safety
cycle.
The hub of the wheel is shaped as a cylinder one or more partitions are made
inside the hub or are part of it, thus forming compartments.
The wheels of the tricycle are fitted as follows.
One or two travelling mitre wheels are fitted to the mitre wheel at the end of
the axle in the first compartment of the hub. They may be covered with a form,
holes are made in the form, travelling mitres and sleeve, used to attach same by
pins to the sleeve.
A revolving mitre wheel with a neck is fitted loosely to the sleeve, the neck
passing through the partition in the second compartment.
A stationary mitre wheel is fitted loosely over the neck in the second compartment
and attached to the partition. Opposite this stationary mitre another mitre wheel
is fitted to the sleeve and attached to the frame.
One or two travelling mitres are fitted to the mitres in the second compartment,
which may be covered with a form. Holes are made in the form, travelling mitres
and neck of the revolving mitre wheel, used to fit them to the neck by pins.
When the driving wheel is connected with the form at the sleeve and turned, it
drives the form and travelling mitre wheels which turn the mitre wheel and sleeve.
The travelling mitres in the first compartment in the hub turn the revolving
mitre wheel whose neck turns the travelling mitres in the second compartment and
turns the mitre wheel on the partition, the hub and wheels of the tricycle.
It follows when the driving wheel is turned once the wheels of the tricycle are
turned eight times.
The wheels of the tricycle can also be without wheel fittings.
More partitions and compartments can be made on the axle and frame and fitted
as previously described and the wheels can be attached to the sleeve.
All parts as described where required will be fitted with ball-bearings, rollers etc.,
for to reduce friction.
To reduce friction the mitres and other wheels can be fitted as follows.

page_text: The mitre and other wheels are of various kinds and are formed and fitted in
various ways. They are divided into male and female wheels.
The periphery of the male wheel has flanges on opposite sides, which are used to
run on the female wheels. Between the flanges projections of various kinds stand
out. Holes can also be made between the flanges which are fitted with pins shaped
in various ways.
In the periphery of the female wheels holes are made of various kinds, used to
receive the projections or pins from the male wheels, and the edges which are on
opposite sides of the periphery are shaped to facilitate the running of the male
wheels or to revolve the female wheels.
The male and female wheels may be also cogged, grooved or may be of demi-
cylindrical shape, and the flanges on the male wheels run on the shaped edges of
the female wheels. The male wheels may also be shaped to receive ball bearings
to facilitate their revolving on the pins which are attached to the spindle or neck
on the revolving mitre.
The gear can also be constructed so that if it be placed in the centre of the
spindle two gears on either side can be driven simultaneously.
In this case the gear is constructed as follows.
To the centre of a spindle, rod or sleeve a partition is fitted, which is fitted on
both sides with a mitre wheel or the wheels may be part of same. Opposite to one
mitre a revolving mitre wheel is loosely fitted to the spindle, which has two necks,
one passing through the partition to the left and the other passing through the
partition to the right.
The travelling mitres in each compartment are attached by pins to each neck of
the revolving mitre wheel and in the compartment of the revolving mitre, the
travelling mitres are covered with a form which is cogged or otherwise formed to
be used for connection with the driving wheel. When the driving wheel is
connected with this form and turned it causes the form to revolve the revolving
mitre, whose two neck turn the travelling mitres in the opposite compartment,
which revolve the revolving mitres to the right and left in the compartments.
In the bottom bracket or other parts only three or four mitre wheels need be
used.

COMPLETE SPECIFICATION.
Improvements in Mechanism to Increase or Multiply Speed to be
used for Cycles and other Contrivances.
JOSEPH BECKER Gentleman 42 Alma Square St. John's Wood London 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:
Improvements in mechanism to increase or multiply speed to be used for cycles
and other contrivances.
My improvements in mechanism to increase or multiply speed consist in the
construction of gears, and in their connection from one to another or others.
The gears are connected from one to the other or others in various ways, and
through their connection from one to the other or others the increase or multiplying
of speed is attained.
For instance to increase or multiply the speed of a rear-driving cycle the bottom
bracket is formed as a cylinder A Fig. 1. At the inside of the cylinder a
partition B or partitions are made which divides the bracket into compartments.
The partition is fitted on one side with a mitre or other wheel C, and on the other
side a groove is made used to receive ball bearings D. A hole is made through
the partition and mitre to receive the shaft or spindle A.
}

page_text: The partition and mitre may also be preferably in one piece and so may the
partition and bracket.
On the inside of the bracket female screws E can be made used to screw the
partition and ends of the bracket into the bracket, and at the outside transverse
Screwed holes are made into the bracket and into the peripheries of the ends and
partition used to fasten the bracket, ends and partition together with screws.
Various joints are also formed on the outside of the bracket used to fit and
fasten the bracket to the frame. An opening is made in the bracket to admit of
the reception of chains or bands to the revolving mitre driving wheel.
The ends of the bracket are of various kinds and can be fastened and unfastened
to the bracket in various ways.
One end of the bracket is formed or fitted with a mitre wheel C the cogs of
which face inside. A centre hole is made through the end and mitre used to
receive the shaft. In the inside of the hole a groove is made used to receive ball
bearings H and a screwed hole J is made in the end outside of the bracket leading
to the groove inside. This hole is used for inserting the balls and is closed by a
screw.
Upon the shaft male screws are partly or entirely formed. Nuts are fitted to
the shaft, which are of various kinds and used in various ways. Some of the nuts
have one or two projecting pins on opposite sides to each other and male screws
are formed upon the ends of them. Other nuts have two screwed holes made in
opposite sides. Some of the nuts may have a combination of these two nuts namely
holes in opposite sides and pins at right angles to the holes.
In other nuts a groove is made in the periphery used to receive ball bearings.
One of the nuts with a groove K is fastened to the shaft opposite the groove in the
end, and the other L is fastened to the shaft opposite the groove in the revolving
mitre driving wheel.
Of the nuts with projecting screwed pins or holes one M is fastened to the shaft
opposite the travelling mitre wheels in the first compartment, and the other N is
fastened to the sleeve in the second compartment opposite the travelling mitres.
When the shaft is fitted to the bottom bracket a mitre wheel with a neck or
sleeve O termed connecting revolving mitre wheel is fitted loosely to the shaft in
the first compartment, the cogs of the mitre facing the cogs of the mitre at the end.
The connecting revolving mitre wheel is formed and fitted in various ways.
:screwed centre hole is made through the connecting revolving mitre wheel used to
receive a male screwed or other sleeve which is fastened to it in various ways.
A
A grocve is made in the back of the connecting revolving mitre corresponding
with the groove in the partition used to receive ball bearings D jointly with
:same.
The male screwed or other sleeve passes through the partition into the second
compartment.
One or two travelling mitre wheels P are fitted to the pin or pins V which
project from the nut on the shaft; or to a collar or other form Z, and engage with
the stationary and connecting revolving mitre wheel. A hole is made in the centre
of the travelling mitre to receive the pin, and a groove is made in the back of
the mitre used to receive ball bearings S.
When the travelling mitre is fitted to the pin the screwed part of the pin
projects beyond the mitre and is fitted with a nut or nut & washer Q' R.
The washer is formed in various ways and in the side which screws to the
travelling mitres a groove is made to receive ball bearings S jointly with the
groove in the travelling mitres. The washer R is placed upon the pin and kept in
place by a nut or nuts Qbehind. The washer may also be kept in its place by
other methods.
.
When the travelling mitres are fitted with a collar or other form, the collar for
purpose of description only is divided into four portions 1, 2, 3, 4, Fig. 2 and is
shaped as follows. Two portions of the circular inside 1, 3, opposite one another
are flat, or are fitted with a plate W.

page_text: An annular groove is made in each of these flat parts or plates corresponding
with the groove in the travelling mitres used to receive ball bearings jointly with
A screwed hole is made in the outside of the collar leading to the groove
used for inserting the balls, the hole being closed with a screw.
same.
A screwed or other hole is made in each of the two portions of the collar
opposite each other or into the four portions used to connect the pins V which
project from the nuts on the spindle to the collar.
The pins and collar Z are fastened together with a sleeve U the sleeve being
screwed on the in and outside.
The male screws of the sleeve screw into the hole in the collar and the female
screws screw on the pin, the sleeve may also be inside without screws.
The collar can also be fastened to the nut in another way by pins or sleeves T
which are male-screwed at both ends.
One end screws into the hole which is in the nut on the spindle and the other
end screws into the hole in the collar. The pin is kept in its place by a nut and
washer behind.
The second compartment is fitted in a similar way to the first. A revolving
mitre driving wheel Y is fitted to the spindle the cogs of the mitre X facing the
mitre C at the partition B.
The revolving mitre driving wheel is fitted to the grooved nut L in the second
compartment and formed in various ways.
:
A centre hole is made in the revolving mitre driving wheel in which a cylindrical
groove is made to correspond with the groove in the nut L used to receive ball
bearings jointly with same.
A screwed hole is made in the outside of the wheel leading to the groove used to
insert ball bearinge, the hole being closed with a screw.
One or two travelling mitres P are fitted to the pins which project from the
nut N on the sleeve and engage with the mitre on the partition C and revolving
mitre driving wheel Y on the spindle A.
The travelling mitres are fastened to the pins, collar or other form in a way
similar as described before.
Upon the periphery of the other end of the bracket male screws are formed.
and a centre hole is made to receive the spindle, the end being fastened to the
bracket.
The cranks are fitted to the spindle A and the revolving mitre driving
wheel Y is connected with the back wheel of the cycle. When the cranks are
turned the travelling mitre P in the first compartment revolves and turns the
connecting revolving mitre wheel which is on the sleeve O, twice.
The travelling mitres P in the second compartment revolve simultaneously with
the connecting revolving mitre in the first compartment, being fitted to the same
sleeve and causing the revolving mitre driving wheel Y to revolve four times.
So that one revolution of the cranks 6 causes four revolutions of the revolving
mitre driving wheel Y provided that the various wheels used are of one uniform
size.
To completely isolate the gear, the driving wheel Y Fig. 1. can be fitted to the
nut on the spindle L Fig. 1 outside the bracket. In this case the driving wheel
is formed at one side as a sleeve. Male screws are formed upon the end of same
used to screw the sleeve to the revolving mitre wheel X in the second compartment
where both are fastened together.
The revolving mitre wheel can also be fitted with a sleeve which passes outside
the bracket. A groove is made in the inside of the sleeve used to receive ball
bearings jointly with the nut on the spindle. A screwed hole is made in the
outside of the sleeve leading to the groove used for inserting the bearings, and
closing with a screw.
Upon the end of the sleeve male screws are formed used to screw and fasten the
driving wheel to the sleeve.
The bottom bracket is also formed and fitted in another way. The bracket.is

page_text: formed as a hollow cylinder A and in each end of it at the inside a groove is made
used to receive ball bearings jointly with the nut on the spindle as formerly
described.
A screwed hole is made from the outside leading to the groove, for inserting the
balls, the hole being closed with a screw.
A slot is left across in a portion of the bracket and the other part opposite
projects. The projecting part B is formed as a half-cylindrical case, the slot and
cylindrical case being used to receive the driving wheel D.
Various joints are formed upon the bracket used to fit same to the frame K of
the cycle.
One or more gears are fitted horizontally between the forks K and they are
connected from one to another or others to the driving wheel and back wheel in
various ways.
The gears are similar as previously described and are fitted in various ways to
the forks.
Holes or half shaped holes are made in the forks on opposite sides used to receive
the pin or spindle which may revolve or be stationary.
A groove is made in the inside of the hole used to receive ball bearings E
jointly with the groove on the nut which is attached to the pin or spindle.
Screwed holes are made from the outside of the fork leading to the groove used
to insert the balls, the holes being closed as previously described.
If half holes are made in the forks the portion in which the half holes are made
is flat.
The pin or spindle is placed in the half hole and is covered with a piece which
is also flat and into which a half hole is made. The piece is fastened and screwed
to the fork. A groove may also be made in each half hole used to receive ball
bearings which are inserted as previously described.
When the pin G is stationary it is screwed to the fork as shown Fig. 6.
A stationary mitre H is placed on the pin at one end and fastened to the fork or
the spindle.
Opposite the stationary mitre a revolving connecting mitre driving wheel J is
fitted to the pin.
One or two travelling mitre wheels P are fitted to the stationary and revolving
connecting mitre driving wheel and are enveloped with a cylindrical form f
which is fitted to the travelling mitre wheels P with ball bearings as previously
described.
The periphery of the cylindrical form may be cogged, grooved or has holes
made in it and engages with the driving wheel D at the spindle. It can also be
connected with the driving wheel by bands or chains.
When a second gear is fitted to the forks, the construction is the same as just
described only the position of the gear is reversed. In the first gear the revolving
mitre driving wheel J is on the left side and in the second on the right, and instead of
the revolving mitre driving wheel of the first gear engaging with the back wheel it
engages with the cylindrical form F on the second gear. The revolving mitre
driving wheel J, of the second gear then engages with the back wheel.
When the cranks are turned the driving wheel on the spindle revolves the
cylindrical form and travelling mitres of the first gear, which turn the revolving
mitre driving wheel, which engages with the cylindrical form of the second gear
and turns same and driving wheel, the latter being connected with the back wheel
of the cycle.
Thus with one revolution of the cranks four revolutions of the back wheel are
effected provided that the various wheels used are all of one uniform size.
Another way to increase or multiply speed is to construct and fit the hub of the
back wheel of the cycle in various ways.
The hub of the back wheel is formed as a hollow cylinder A. Fig. 3. A groove
is made in each end of the hub at the inside used to receive ball bearings C. One
or more partitions B are made inside the hub dividing it into compartments and

page_text: these are formed and fitted to the bub in a similar manner as previously described
in the first bottom bracket. One or two grooves can also be made into the centre
hole of the partition used to receive ball-bearings jointly with the grooved nut
which is fastened to the sleeve of the connecting revolving mitre driving wheel.
When two compartments are used the first compartment is fitted as follows. A
stationary mitre wheel D with a neck or sleeve E is fitted to the shaft and fastened
to it, the cogs of the mitre facing inside the hub. A circular groove is made on
the outside of the neck or sleeve used to receive ball bearings J jointly with the
driving wheel. The ball bearings are inserted as previously described.
Opposite the stationary mitre wheel a connecting revolving mitre wheel O is
formed and fitted to the shaft in a similar manner as previously described in the
first bottom bracket, the neck or sleeve passing through the partition into the
second compartment. One or two travelling mitres P engage with the stationary
and connecting revolving mitre.
The travelling mitres are covered with a cylindrical form F, the form and
mitres being fitted together and all arrangements of bearings etc., being similar in
manner as previously described in the arrangement of travelling mitres and collar
in the first bracket.
The form F is fitted and formed in various ways. An extension G is formed at.
the outside of the form a groove is made into it used to receive ball bearings C
jointly with the groove in the end of the hub.
The projecting portion H outside the hub is formed and fitted in various ways.
The periphery of the projecting portions is either cogged, grooved, or has holes
made in it, used for the reception of chains or bands which connect it with the
driving wheel at the bottom bracket. The projecting part can also be formed or
fitted as a bevel or mitre wheel, and can be closed. A centre hole is made in the
closing portion to admit the neck or sleeve E of the stationary mitre wheel D.
groove is made at the inside of the hole used for the reception of ball bearings J
jointly with the groove in the neck of the stationary mitre wheel. The balls are
inserted as previously described.
A
The second compartment is fitted in a similar manner to the second compartment
in the first bottom bracket.
Opposite the mitre wheel at the partition a stationary mitre K is fitted to the
shaft a the cogs of the mitres facing each other.
A centre hole is
The stationary mitre K has a neck projecting outside the hub.
made through the neck and mitre to receive the shaft A. Various joints can also
be made upon the neck K and the neck E used to fit the gear to the form.
The mitre wheel has an extension L in which a groove is made to receive ball
bearings C jointly with the groove in the hub.
The neck of the mitre is fastened to the spindle by means of screwed holes and
screws or other methods.
The projecting form of the hub H is connected with the driving wheel of the
cycle. The driving wheel is turned and causes the projecting form and travelling
mitres in the first compartment to revolve, which turn the connecting revolving
mitre which is on the sleeve, twice. The travelling mitres in the second com-
partment revolve simultaneously and drive the mitre at the partition B four times.
So that one revolution of the driving wheel causes four revolutions of the mitre at
the partition with which the hub and back wheel travel; provided that the various
wheels used are of one uniform size.
To increase or multiply the speed of a front driving cycle the hub is fitted as
follows.
The hub is formed as a hollow cylinder A Fig. 4 female screws E are made wholly
or partly on the inside.
At the inside of each end of the hub, a circumferential groove is made used to
receive ball bearings or rollers, C.
One or more partitions B are made in the hub which divides same into
compartments.

page_text: The partitions are formed and fitted as previously described in the first bottom
bracket.
The ends which close the hub are of various kinds and formed in various ways.
A mitre wheel D is fitted to each end or both may be in one piece.
A circumferential groove is made in the periphery of the ends used to receive
ball bearings C jointly with the grooves of the hub.
In the centre of the ends a boss F projects. A hole is made through the boss,
end, and mitre wheel, used to receive the shaft a. In the inside of the hole a
cylindrical groove is made used to receive ball bearings J jointly with the nut
attached on the shaft.
The boss F receives the fork d which is fastened to both boss and closing end of
the hub by screws and screwed holes or other methods.
The periphery of the ends can also be without a groove. In this case a cylindrical
groove is made in the side of the closing end to receive ball bearings M.
When the closing end is fitted to the shaft the balls are placed in the grooves.
A ring N whose periphery is screwed, is screwed and fastened to the hub to keep
the bearings in their place. The ring is formed in various ways to secure it being
dustproof, and an annular groove can also be made into the side of the ring to
receive the ball bearings M jointly with the closing end.
When the hub (A, Fig. 5) is divided into three or more compartments one of the
closing ends of the hub is formed or fitted with a cylindrical or skeleton cylindrical
extension, or bars; if bars are used then the ends of the bars are connected
together with a ring or collar.
The cylindrical extension projects inside the hub and is used to receive one or
more partitions, the partitions being formed and fitted as previously described.
Female screws are formed on the inside of the extension used to screw the
partition to the extension; and extension and partition are screwed together from
the outside by screwed holes and screws.
When only one partition is fitted to the extension the partition may be preferably
part of it as shown.
When the hub is divided into three compartments the first compartment is fitted
as previously described in the hub with the exception that the travelling and
revolving mitre revolve in the cylindrical extension H which projects from the
closing end.
A partition D with a mitre wheel is fitted to the end of the cylindrical extension
or is part of same, the cogs of the mitre facing the inside of the hub. A centre
hole is made through the partition and mitre wheel, and the neck of the revolving
mitre wheel O passes through the partition into the second compartment, the
second compartment being fitted as previously described.
One or two travelling mitres P are fitted to the mitre at the end of the
cylindrical extension H and to a second connecting revolving mitre wheel which is
formed and fitted as previously described.
The travelling mitres are connected with the sleeve of the revolving mitre as
previously described.
A second partition B with a mitre wheel is fitted and fastened to the hub and
divides the hub into three compartments, the mitre facing the mitre wheel at the
other closing end. One or two travelling mitres are fitted to the mitre at the
partition, which is fastened to the hub and to the mitre at the closing end; and
they are connected and fitted as previously described to the sleeve of the second
revolving mitre wheel.
The forks of the cycle frame d are fitted to the projecting bosses on the closing
ends. The cranks e are turned, the travelling mitre in the first compartment
revolves and turns the revolving mitre wheel O, whose neck revolves the travelling
mitre in the second compartment twice. The travelling mitre in the second
compartment revolves and turns the revolving mitre O' four times, whose neck in
the third compartment revolves simultaneously and turns the mitre wheel at the
partition B with which the hub A and wheel are connected.

page_text: It follows by one revolution of the cranks, eight revolutions of the wheel are
attained.
When two compartments are used in the hub of the front driver the cylindrical
extension from one end of the hub is not required. See Fig. 4.
The travelling and the connecting revolving mitre wheel are fitted in the first
compartment of the hub as previously described and the sleeve of the connecting
revolving mitre wheel passes through the partition which is fastened to the hub..
It follows by one revolution of the cranks four revolutions of the mitre wheel at:
the partition which is attached to the hub and wheel, are attained.
The hub with gear as described on front driving cycles can also be used for the
hub of rear-drivers. In this case various joints are formed upon the surface of
the projecting bosses which are at the ends of the hub, used to attach the hub to.
the frame.
A slot is made in one or both bosses used to admit chains or bands to the wheel.
or wheels which are fitted and attached to the shaft outside the hub, and the chain
connects the wheel or wheels in the bosses with the driving wheel at the bottom..
bracket.
The geared hub of the front driving cycle can also be used as a bottom bracket.
of a safety or other cycle.
In this case no slot in the boss is required. The joints are formed upon the
surface of the bosses to suit the frame and are attached to same.
The periphery of this hub is formed in various ways, either cogged, grooved or
having holes made in it to receive chains or driving bands which are of various:
kinds and which connect it to the back wheel of the cycle.
Tricycles and quadricycles are improved in a similar way as described before.
The brackets or hubs as previously described are fitted to the frame and are
connected with the hub or revolving form on the axle by either chains or bands.
On the axle one or more partitions are made, the partitions fitting loosely over
the axle and are attached in various ways to the frame or are part of same.
Compartments are formed in a similar way as described in the bracket and
hubs.
A stationary mitre is fitted to the partition at the frame or is part of it..
Opposite the stationary mitre a connecting revolving mitre driving wheel is fitted
to the axle, the sleeve of same passing through a second partition. One or two.
travelling mitre wheels are fitted to the nitre at the partition and to the connecting
revolving mitre wheel.
They are covered with a cylindrical form the periphery of which is cogged,
grooved or has holes made in it for the reception of chains to connect it with the
driving wheel on the bracket or hub used instead of bracket.
The cylindrical form is formed and fitted to the travelling mitres in a similar
manner as previously described in the bottom bracket.
Opposite the mitre at the second partition, a second connecting revolving mitre,
wheel is fitted to the axle the cogs facing the mitre at the partition. The sleeve
of same when no further compartments are added is fastened to the axle.
One or two travelling mitres are fitted to the mitre at the partition and to the
connecting revolving mitre wheel. They are fitted and fastened to pins which.
project from the nut which is fastened to the sleeve of the first connecting revolving
mitre wheel.
The wheels of the cycle are fitted and fastened to the axle. The driving wheel
is connected to the revolving form in the first compartment. The cranks are
turned, the driving wheel revolves the revolving form and travelling mitres in the
first compartment, which, turns the connecting revolving mitre wheel whose sleeve
revolves the travelling mitres simultaneously in the second compartment, which
turns the second connecting revolving mitre wheel which is fastened to the axle.
Thus from one revolution of the cranks four revolutions of the axle and wheels
are attained, provided the wheels used with and in connection of the gear are of
one uniform size.

page_text: To reduce friction the mitres and other wheels are fitted as follows.
The mitre and other wheels are formed and fitted in various ways. They are
divided into male and female wheels.
The periphery of the male wheel Fig. 6 has faces on opposite sides which are
used to run on the female wheels. Holes are made between the faces which may
be screwed. They are fitted with pins shaped in various ways, the one end of the
pin may be screwed to fit into the holes between the faces and the other end may
be egg-shaped. This is one way, or the pins can be part of wheel.
In the periphery of the female wheels holes are made used to receive the pro-
jections or pins from the male wheels. The holes can be screwed and fitted with
male screwed sleeves for the purpose of, when the holes are worn out they can be
replaced by other sleeves.
Ordinary cogged wheels may also be used provided with running faces or
flanges.
The arrangement of my invention as hereinbefore described is intended to show
one method of carrying out same, as regards cycles & similarly constructed machines
but it is obvious that the arrangement of bearings, shafts, and method of con-
structing the gears when used for other contrivances besides cycles, may be varied
by other known methods. Wherever necessary covered holes are made in the
gears for lubricating purposes.
