PROVISIONAL SPECIFICATION.
Improvements in Velocipedes.
JOHN THOMAS MOORE The Firs, Langley Macclesfield Chair Manufacturer, do
hereby declare the nature of my invention for IMPROVEMENTS IN VELOCIPEDES to be
as follows:
And possessing arrangements by which the machine may be made to go at the
normal speed of the driving wheel whether road, chain, or other wheel, and
also a simple arrangement of gearing by which any increase of speed desirable
may be attained. To produce this variety of speed, the hub of the driving wheel runs
loose upon its axle and when speeded up, it is run quicker than the axle (or the axle
may run with the hub for high speed and faster than the hub for slow speed).
To produce normal speed in case of a machine provided with geared and normal
speed motion the axle and hub are geared together by means of a ratchet & pawl,
recessed balls, or other arrangement.
The following example is given to illustrate its application to a Safety Bicycle.
To a safety Bicycle geared up to 60" sixty inches it is desired that it should be made
to go at 30" thirty inches when necessary (or half speed) for hill climbing. (Three
speeds may be had slow normal & fast). The chain wheel upon the crank axle is
loose upon its axle & has cast upon one side of it a toothed spur wheel of say 2" two
inches diameter beside this spur wheel but fast to the axle is another spur wheel of 11"
one & half inches diameter, between this wheel & the fork is a collar, loose upon the
axle, this collar carries by means of a stud pin a double wheel of 1" one & half
inches to engage with the fastened 11" one & half inch wheel & a 1" one inch wheel
to engage with 2" two inch wheel a sliding rack is fixed upon the collar this rack
engages with the wheel & so prevents it turning upon the stud it prevents any of the
wheels turning whilst it is in use the wheels & collar are simply carried with
the axle. To go at half speed a stud or other arrangement pressed down by the
handle this prevents the collar turning round & unlocks the gear wheels with the
desired effect.

COMPLETE SPECIFICATION.
Improvements in Vélocipedes.
JOHN THOMAS MOORE Draper & chair Manufacturer The Firs Langley Macclesfield
do hereby declare the nature of my invention for IMPROVEMENTS IN VELOCIPEDES
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This Invention relates to improvements in the construction, & arrangement, of what
are known as variable speed, or Hill climbing gears.
The principle as explained by means of a detailed example in my provisional
specification, is to lock the whole of the working parts together, for one speed and to
release and cause them to work for another speed.
Some of these various methods are herewith specified, and illustrated.
Fig. 1 is an illustration of an arrangement for gaining speed. A is a plate or disc
loose upon the axle, and has in connection firmly fixed to it a step collar B. with
notches, or teeth, upon it. C is a collar with notches, or teeth upon the side, which
slide into the corresponding spaces upon the collar B. There is also a space or groove
suited for a runner, on the face or circumference of the collar C. This collar is made
to revolve with the axle by means of a feather or key and slot, which causes the collar

page_text: to turn, but does not prevent it sliding upon the axle when actuated by the runner E.
D is a pawl or detent, which when raised, or lowered, not only actuates the runner E
but if pressed down into one of the spaces of the collar B, prevents the collar B the
plate or disc A¹ and the wheels G. from revolving round the central axle, the same
action also throwing the collar C, out of gear with the collar B.
The wheel F is fixed firmly to the axle, the wheels G are either cast or made
together in one piece, or are joined by some suitable method. The wheel H is
secured to the chain wheel I. and revolves with it. In use upon the detent D
being lifted the collar C. locks into the collar B and so locks the train of wheels F. GG
& H that they do not turn or work, but simply revolve around and at the same number
of revolutions as the axle.
To increase the speed of wheel I. the detent D is dropped into one of the
spaces of the collar B, this prevents the disc A from revolving with the axle, and
as the wheel F is fixed to the axle, it communicates motion to H & I thro the
wheels G. G.
The wheels F. G. H. in this illustration may be varied in size to produce any rate
of speed high, or low,that may be desired. Fig. 2, another arrangement is for A F
&G to change places, so that F will be secured to the collar B and will be loose upon
the axle. A will then be fast to the axle. The pin or spindle K connecting the two
wheels G. will run loose thro A and will carry the wheel G. round the wheel F. As
the motion of the wheels G is reversed, by this movement, an inter geared wheel will
be required between G & H. this arrangement is useful where slight increase of speed
is required or the wheel G. may gear into an internal toothed wheel, on I as in Fig. 3
F 3. A & B are here shewn in one piece the teeth here gear directly into the
corresponding places in wheel F for normal speed. To gear up the wheel, F is
geared to the teeth M, & by them held rigid whilst the wheel G. revolves around it.
Where slower than normal speed is required with this class of gear, it is placed upon
the driven instead of the driving wheel (i.e.) motion is first communicated to wheel I
and through G to the spindle.
Another form in which this principle may be used is for the central of 3 bevel
wheels, to travel round a fixed bevel wheel, and so to gain speed or to be locked
and retained at normal speed, the wheels G. would be represented by one horizontal
"instead of vertical wheels with bevel teeth gearing into F & H.
Having now particularly described and ascertained the nature of the said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
First. The combination of releasing and locking movements or vice versa, as shewn
by Figs. 1 A. 2 A. 3 A. or other equivalent arrangement for the purpose set forth,
and specified.
Second. The combination of wheels etc. in conjunction with releasing, and locking
Inovements, as herein set forth, and for the purpose specified.
