I JOHN ADAM THUMLING of 19 Greek Street Soho Square in the County of
Middlesex Engineer, do hereby, declare the nature of my invention for "IMPROVE-
MENTS IN THE ARRANGEMENT AND APPLICATION OF ANTI-FRICTION CONE ROLLERS
TO THE AXLES OF WHEELS AND BEARINGS OF ALL KINDS" to be as follows:-
My Invention relates to the application of a number of cones or rollers used for
reducing friction which are kept at equal distances apart by the use of a division
projection or plate on which the spindle joint or surface to which the friction cone
rollers are applied revolves or turns.
The cones are so placed that their smallest diameter faces or points to the centre
which makes the action centripetal.
The division plates are fast or loose fast when the wheels revolve, loose when
the spindles revolve, it is only to be considered whether the motion is driving or
driven.
The cone rollers for the spindle axles differ somewhat from the cone rollers I use
for joints or surfaces. The cone rollers for axles require to have at each end a
small trunnion parallel bearing or journal to run in holes of the division plate and
a groove in the screw cap that closes the end of the bearing. The division plate
ought to be screwed or fixed fast in the hub of the wheel.
My invention can be applied to turntables, turnstiles, cowls, pulleys, swing
bridges, swivel action for cranes, all large joints, large or small surfaces where
great friction takes place, as in castors for safes, furniture, velocipedes or other like
purposes.

page_text: I JOHN ADAM THUMLING of 19 Greek Street Soho Square in the County of
Middlesex Engineer 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 the application of a number of cones or rollers used for
reducing friction which are kept at equal distances apart by the use of a division
plate ring or collar as the case may be according to the character of the joint or
surface to which the friction rollers are applied.
The cones in surface joints are so placed that their smallest diameter faces or
points to the centre which makes the action centripedal. When applied to axles,
of wheels the centre lines of the cones run parallel with the centre lines of the
main axle. The division plates are loose.
The cone rollers for the spindle axles differ, somewhat from the cone rollers I use
for joints or surfaces. The cone rollers for comparatively large axles require to
have at each end a small trunnion parallel bearing or journal to run in holes of the
division plate and a groove in the screw cap that closes the end of the bearing.
My invention can be applied to the principal joints of turntables, turnstiles,
cowls, pulleys, swing bridges, swivel action for cranes, all large joints, large or
small surfaces where great friction takes place as in castors for safes furniture
velocipedes or other like purposes.
Figures 1 and 2 of the drawings hereto annexed show a plan (with top plate
removed) and a section of a frictional bearing having cone rollers applied thereto
in accordance with my invention such bearings being applicable to turntables turn-
stiles swing bridges and other like purposes.
a is a revolving plate and b a fixed bed or bearing c are a series of conical rollers
which are kept at equal distances apart by the division plate d which may be con-
siderably varied in form as it may be a plate, ring or collar with openings in the
circumference for receiving the rollers c. A circular groove is formed in the fixed
bed b and cover plate a so that the ends only of the cone rollers c come in contact
therewith thereby greatly reducing the friction between the two surfaces a and b.
Figures 3, 4, 5, 6, 7 and 8 show several views of a bearing having anti-friction
cones or rollers arranged and combined therewith in accordance with my improve-
ments and suitable for being applied to the axles of wheels bicycles or other like
purposes the corresponding parts being marked with similar letters of reference to
those previously described.
Figures 9 and 10 show my improvements as applied to casters for safes furniture
or other like purposes.

page_text: 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:-
The improved arrangement and application of anti friction cone rollers to the
axles of wheels and bearings of all kinds such as turntables turnstiles cowls pulleys
swing bridges swivel actions for cranes and all large joints and small surfaces
where great friction takes place as in castors for safes furniture velocipedes or other
like purposes substantially in the manner herein before described.
