PROVISIONAL SPECIFICATION.
Improvements in Cycles, Vehicles, Motor Cars, and the like..
HENRY O'REILLY, 249, Clonliffe Road, Dublin, Master Cooper, do hereby
declare the nature of this invention to be as follows:-
A gear for cycles, vehicles, motor cars & the like consisting of cog wheels with
teeth revolving on ball, cone, or other bearing and by means of internal or external
toothed or wheels constructed with both, acting on the back of an external
toothed wheel fixed on the hub of the driving wheel and connected by a series
of wheels with one occupying the place of the present crank wheel and in order
to accomodate the wheels composing the gear, I substitute for the back part of
the present frame, two arched stays braced together by stays of similar construc-
tion which carry the axles of the intermediate wheels and an improvement in
ball bearing by which the ball race is made of convex or in conjunction with
concave sides. That is to say an improvement in adjustable ball bearing in which
the ball races are formed of a convex projection as in A Figure 2 or projections
as in A Figure 1 extending throughout the inner circumference of the drum or
roller and two convex projections as B Figure 2 which encircle the axle C and
have rectilinear bases at right angles thereto.
And also in which the ball races are formed of two convex projections as A
Figure 1 extending throughout the inner circumference of the drum or roller and
the concave sides of two cone shaped projections B on the axle C and having
rectilinear bases at right angles with the axle and turning away from its centre
as shown in drawing.
I, HENRY O'REILLY, of 249, Clonliffe Road, Dublin, Ireland, Foreman Cooper,
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:-
This invention relates to improvements in or relating to cycles vehicles, motor
cars and the like consisting of gear wheels whose teeth are formed of rollers
revolving on ball cone or other bearing; these wheels being so arranged as in
case of the cycle illustrated to transmit motion direct from the pedal crank axle
CD 077

page_text: to the hub of driving wheel thus dispensing with the driving chain now generally
used.
This invention further comprises improved ball bearing for use with this gear
or otherwise generally applicable to revolving shafts axles or rollers or the like
and to a novel frame or support for the wheels constituting above or other gearing.
In the accompanying drawings Fig. 1 shows a side view of this improved gear
Fig. 2 is an alternative form of gear and Fig. 3 and 4 show improved form of
ball bearing for use therewith or otherwise generally applicable, Sheet 3 shows
a cross section view of one of the wheels of which Sheet 1 and 2 show the side
view, A being the roller teeth fastened between the two sides of rim B B by
means of nuts C C.
Referring to Fig. 1 F represents a wheel attached to the pedal crank axle
engaging by means of its revolving teeth or rollers through wheel I) with a series
of similarly constructed wheels or ones with suitably constructed stationary teeth
of which C and B are both fixed on the same axle the latter B having internal
teeth engaging with wheel or pinion A fixed on the hub of driving wheel while
the former C engages the wheel D on one side but passes behind and does not
engage with wheel or pinion A on the other side, G G are the pedal cranks an E E
represents two arched stays in substitution of the present back or chain stay of
a cycle which combined with the cross stays H H form the necessary frame or
support for the bearing for the wheels B C and D) and of which the frame sur-
rounding wheel on Sheet 3 show the side section D D being the cross stays H H
shown in Sheets 1 & 2 and connected with the main stays at points K, K, K, K
and thus form the necessary frame for the support of the wheels B, C & D.
Those stays having suitable adjusters with lock nuts attached to the axles of the
several wheels by means of which they can be adjusted or moved into closer or
more distant contact so as to adjust them at the point at which they will work
with the greatest freedom and there secured. Referring to Fig. 2 which shows an
alternative form of gear, the wheel B is constructed to work with inside contact
with wheel or pinion A on the hub of driving wheel and also with outside contact
on opposite side with wheel D the revolving teeth of wheels A and D passing
inside the collors which hold the revolving teeth of wheel B thus reducing by
one the number of wheels necessary to form the connection between the driving
wheel axle and pedal crank shaft.
Fig. 3 shows one form of improved ball bearing for use with this gear in which
the ball race is formed of two convex projections A A extending throughout the
inner circumference of the drum or roller, and the two concave sides of two cone
shaped projections B B on the axle and having rectilinear bases at right angles
with the axle. The cone shaped projections are adjustable as shown and thus
form hetween their concave surfaces and the before said convex projections A A
a ball race in which the halls will not slip laterally, thus lessening friction.
Fig. 4 shows another form of ball bearing in which the ball race is formed of
convex projection A extending throughout the inner circumference of the drum
or roller and two convex projections 13 B encircling the axle and also having
rectilinear bases at right angles to said axle and suitable adjustment.
The advantages of this method of gearing are that it obtains a high gear at the
same time reducing friction to a minimum and also obviates the side twist or
strain which occurs in bevel gearing as at present used on cycles etc.
.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In cycles and the like a gear consisting of a series of especially constructed
wheels having teeth formed of revolving rollers with or without ball bearing
arranged internally or externally on the wheels engaging with wheels of similar
construction or with wheels furnished with suitable stationary teeth the said

page_text: wheels being so arranged as to establish direct communication between the driving
wheel axle and the pedal crank shaft substantially in the manner discribed and
illustrated.
2. A frame for supporting some or all of the wheels constituting said or other
gearing said frame being composed of arched stays braced together by cross stays
and provided with suitable adjusters and lock-nuts substancially as illustrated
and discribed.
3. Ball bearings in which the ball race is formed of convex projections A A
extending throughout the inner circumference of the roller and the concave or
convex surfaces of projections 1 B on the axle, the said latter projections being
capable of adjustment substancially in the manner discribed and illustrated.
