IMPROVEMENTS IN BEARINGS FOR VELOCIPEDES
Year: 1885

page_text: I, HERBERT ATHELSTAN BARROW, of the 'Cot,' Witton, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BEARINGS FOR VELOCIPEDES" to be as follows:-
This Invention relates to a novel construction of bearing for the axles of
velocipedes.
For this purpose we employ a hollow box or case of brass, gun metal, steel or
other suitable metal, and within this case we fit three or more concentric rings also
of metal in a gradually diminishing series so as to revolve freely within and upon
each other. To lessen the friction, the rings are channelled, grooved or recessed
around the periphery, such channel,, groove or recess., forming a receptacle for
lubricating matter.
The friction, which under ordinary circumstances would be generated between
the axle and bearing and confined to two surfaces presenting a comparatively small
area will according to my Invention be distributed over the whole of the contiguous.
surfaces of the rings which by constantly changing their relative positions will not
be liable to wear away irregularly.

I, HERBERT ATHELSTAN BARROW, of the "Cot," Witton, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BEARINGS FOR 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 a novel construction of bearing for the axles of
velocipedes.
For this purpose I employ a hollow box or case of brass, gun metal, steel, or
other suitable material, and within this case we fit three or more concentric rings
also of metal in a gradually diminishing series so as to revolve freely within and
upon each other. To lessen the friction, the rings are channelled, grooved, or
recessed, around the periphery, such channel, groove, or recess forming a receptacle
for lubricating matter.
The friction which under ordinary circumstances would be generated between
the axle and bearing and confined to two surfaces presenting a comparatively small
area will according to my Invention be distributed over the whole of the contiguous
surfaces of the rings which by constantly changing their relative positions will
not be liable to wear away irregularly.
And in order that my Invention may be more fully understood I have hereto
annexed a sheet of Drawings illustrative thereof.
Figure 1 is a side elevation of my improved bearing and Figure 2 is a sectional
view thereof. Figure 3 is a lateral section and Figure 4 shews the rings separately.
A is the hollow box or case and B are the rings which are made in a gradually
diminishing series so as to fit easily one within the other.
The rings are turned down or reduced in diameter between the two ends, thus
reducing the amount of bearing surface and affording space for oil or other
lubricant. The ring nearest the axle is attached thereto by a screw a and revolves
therewith, thus preventing the axle from wearing away, the total amount of
friction being distributed amongst the series of rings which may consist of any
convenient number.
One side of the hollow box A is solid and forms the bottom thereof, but the
other is closed by means of a cap C which is screwed thereon.
I do not confine myself to the shape of hub or attachment D as this forms no
part of my Invention."
Having thus 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 employment of a series of rings B contained in a box A as a bearing for
the axis of a velocipede wheel, substantially as herein shewn and described.
