PROVISIONAL SPECIFICATION.
Improvements in and relating to Bicycles and other Cycles.
I JAMES LEACH of Waithlands Milnrow Road Rochdale Spring Maker in
the County of Lancaster do hereby declare the nature of this invention to be as
follows:-
My invention relates to bicycles and other cycles.
The object of my invention is to provide a device for the prevention of dirt,
mud, or grit entering or passing between the ball bearing or friction cup piece and
the axle of the driving gear or other wheel thus-when such is the case-impairs
the efficiency of the machine and wears away the ball cup-piece.
This invention is applicable to such part as now described or may be to any
wheel or wheels of the cycle.
According to my arrangement I form on the bush of the one extremity of the
crank pedal that is, the extremity which is mounted on the driving axle-or cut
thereon on the face next to the ball cup piece or hub of the gear wheel a
number of concentric channels or spaces. I also provide on or cut in the face of
the ball cup piece or wheel hub a corresponding number of concentric channels or
spaces but I preferably make the bush piece of the crank of larger diameter than
the ball cup piece or the one channelled piece larger than the other as may be
desired. The directing parts or walls of the one are adapted to enter or loosely
fit into or within the corresponding concentric channels or grooves of the other,
but so that the grooved face of the one is capable of revolving or turning within
the other when actuated by the pedal crank, thus according to my invention the
surface or surfaces of the axle or axles may be protected from contact with mud
thus a mud guard is formed for the machine.

Improvements in and relating to Bicycles and other Cycles.
I JAMES LEACH of Waithlands Milnrow Road Rochdale in the County of
Lancaster Spring Maker, 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:-
My invention relates to bicycles and other cycles.
The object of my invention is to provide a device for preventing dirt mud or
grit entering or passing between the ball bearing or friction cup and the axle of the
driving gear or other wheel, as when such is the case the efficiency of the machine
is impaired and the ball cup worn away.
This invention is applicable to such part as now above described or may be
applied to any wheel or wheels or to any convenient rotating or other bearing part
of the cycle.

page_text: According to my arrangement I form on the bush or collar part of the one
extremity which is mounted on the driving axle or I cut therein on its face part
that is, the surface thereof next to the ball cup or may be next to the hub of a
wheel of the cycle a number of concentric channels, spaces, or grooves. I also
provide on or cut in the adjoining or contiguous face or surface of the ball cup
piece or wheel hub or collar a corresponding number of concentric grooves or
spaces.
I preferably make the bush or collar piece of the crank pedal piece of larger
diameter than the ball cup piece or the one grooved piece larger than the other
as may be desired, that is, so that the dividing parts or walls of the one shall
pass or enter into and fit loosely within the corresponding concentric grooves of
the other but so that the grooved face of the one may be capable of revolving or
turning round and within the other-when actuated by the crank piece or pedal
or when the wheels or motion parts are in use or motion-thus according to my
invention the bearing surface or surfaces of the axle or axles may be protected
from contact with mud, dirt, or other injurious matter thus according to my
invention an apparatus is provided forming practically a mud or dust-proof appliance
to be employed at the parts above indicated.
In order that my invention may be clearly understood I have hereunto annexed
a sheet of drawings in which like letters of reference indicate like parts throughout
the various figures therein shewn.
Fig. 1. is an elevation of the driving mechanism of a cycle shewing a part of my
invention applied thereto.
Fig. 2. is an elevation of Fig. 1 shewing my invention in section.
Fig. 3. is a sectional view of my invention drawn to an enlarged scale.
Fig. 4. is an illustration shewing the two parts of my invention detached from
each other also from any part of the cycle.
Fig. 5. is an illustration shewing my invention in connection with the hub or boss
of a wheel.
Fig. 6. is the grooved piece or counterpart of the grooved portion of the
wheel hub.
Fig. 7. is an illustration shewing the reverse side of the grooved portion of
the wheel hub as shewn in Fig. 5,. which side forms the ball cup shewing the
balls therein.
a. is the bush or collar piece of the driving or gear wheel b. which piece or
part I provide with any number of concentric grooved spaces a¹ a². I preferably
employ two as shewn in the drawings. I also provide the contiguous face or
surface of the ball cup c with a corresponding number of grooves or spaces c', c
the friction pieces or balls & being situate in the ball chamber space or cup the
ball cup piece is secured or screwed into the bracket or support e, of the
framework of the machine as heretofore.
My invention as shewn in Fig. 5 is applied to the hub or boss of a wheel.
The concentric grooves or division parts or walls a' a' are cut or formed on the face
thereof thus forming spaces or grooves as a into which latter the concentric walls
or division pieces fff of the boss or collar piece 9 are adapted to enter or
loosely fit therein which piece g. may be the collar piece of a pedal crank piece h.
as shewn in Fig. 6. or may be a fixed part or portion of the machine frame.
The invention and as shewn in the drawings clearly shew that the concentric
walls or division pieces or parts of the one are adapted to loosely fit within the
concentric spaces of its counterpart or piece and so adapted as to cover or protect
the bearing parts i. ¹ of the axle 2 or may be other bearing parts, from dust or grit
as the spaces jj existing between the collars a and h' of the wheel and pedal crank
respectively and the fixed bracket e. of the frame has not a direct connection with
the axle or other bearing but only in a circuitous manner and through the inter-
vening spaces or concentric grooves of the duplicate pieces a and c. or a and g or
any other similar parts- or pieces thus any dirt dust or grit which would pass
between the ball cup piece and the contiguous part as now arranged, that is, the

page_text: face of each to abut against the other-is according to my invention obviated as
by the interposition of the concentric walls of the one piece and the corresponding
concentric grooves of the other piece I accomplish or effect for all practical
purposes dust proof bearings or I am enabled to greatly minimise the accretion or
accumulation of objectionable matter thereon.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is.
1. In combination the axle or bearing 2 with the grooved collar or bush
piece a. of a wheel hub or other convenient part of a cycle and a corresponding
grooved piece or counterpart provided on the pedal crank or any other convenient
part of a cycle whereby one part fits within and is capable of turning within the
other substantially as and for the purposes herein fully set forth and illustrated
in the drawings hereunto.
2. The collar or other pieces having grooved surfaces the one piece fitting within
the other as and for the purposes herein set forth.
3. The collars or pieces one of which is of larger diameter than its counterpart
whereby the one part is capable of and adapted to enter into the other as and for
the purposes herein set forth.
