PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
We CHARLES MONTAGUE LINLEY of 16 Carmalt Gardens, Putney in the
County of Surrey, and JOHN BIGGS of 57 Lynette Avenue, Clapham Common,
Clapham, in the County of Surrey, both Engineers, do hereby declare the nature
of this invention to be as follows:-
:-
Our invention relates to an improved construction of bearing brackets for the
pedal crank axles of velocipedes, and it has for its object simplification of construc-
tion and economy in cost of production.
We attain this end in the following manner:- We stamp out a flat steel plate of
the required shape to form a split barrel with lugs for locking screws, and we roll
or fashion this plate to form the said split barrel. We then face the ends of the split
barrel to ensure their being absolutely true with one another. In each end of this
barrel is placed a steel cup to form the races for the ball bearings. These cups
are preferably stamped up out of sheet steel and have flanges on them to define
their positions when inserted in the ends of the split barrel. These cups are locked
in position by contracting the split barrel by means of transverse screws passing
through the lugs on the said split barrel. These screws also fix the forward end of
the lower back fork carrying the driving wheel to the said pedal crank axle
bracket.
On to the centre of the split barrel is brazed or otherwise fixed a split ring or
collar carrying suitable lugs to receive the other tubular members of the frame, and
we prefer to make both this split collar and its lugs and also the crown piece of the
lower back fork, out of sheet steel stampings according to the method set forth in
another application for Letters Patent filed by us; or as an alternative method of
attaching the other tubular members of the frame, we stamp or raise up suitable
circular shoulders, or their equivalents, in the split barrel when it is yet in its blank
form, the said shoulders, or their equivalents, being adapted to receive the ends of
the tubular members of the frame.

Improvements in and relating to Velocipedes.
We CHARLES MONTAGUE LINLEY of 16 Carmalt Gardens Putney in the
County of Surrey and JOHN BIGGS of 57 Lynette Avenue Clapham Common in
the County of Surrey, both Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
Our invention relates to an improved construction of bearing brackets for the
pedal-crank axles of velocipedes, and it has for its object, simplification of construc-
tion and economy in cost of production.
We attain this end in the following manner :-
We stamp out a flat steel plate of

the required shape to form a split barrel with lugs for locking bolts or screws, and
we roll or fashion this plate to form the said split barrel. We then face the ends of
the split barrel to ensure their being absolutely true with one another. In each end
of this barrel is placed a steel cup to form the races for the ball bearings. These
cups are preferably stamped up out of sheet steel and have flanges on them to define
their positions when inserted in the ends of the split barrel. These cups are locked
in position by contracting the split barrel by means of the bolts or screws passing
through the lugs on the said split barrel. These bolts or screws also fix the forward
end of the lower back fork carrying the driving wheel to the said pedal-crank axle
bracket.
On to the centre of the split barrel is brazed or otherwise fixed a split ring or
collar carrying suitable sockets or lugs to receive the other tubular members of the
frame, and we prefer to make both this split collar and its lugs and also the crown
piece of the lower back fork, out of sheet steel stampings according to the method
set forth in our Patent No. 2660 of 1891, or as an alternative method of attaching
the other tubular members of the frame we stamp or raise up suitable sockets or
their equivalents in the split barrel when it is in its blank form, the said sockets or
their equivalents being adapted to receive the ends of the tubular members of the
frame.
In order that our invention may be fully understood we will more particularly
describe it making reference to the accompanying drawing in which
Figure 1 is a view in side elevation of a bearing bracket constructed according to
our invention and
Figure 2 is a view-partly in section-in longitudinal elevation thereof.
Figure 3 is a view in sectional plan of the split barrel.
Figures 4 and 5 are views in side elevation and sectional plan respectively of one
of the bearing cups.
Figure 6 is a view in transverse sectional elevation of the split barrel showing
the method of mounting the sockets to receive the members of the frame thereon,
and
Figure 7 is a similar view showing how the said sockets may be formed in the
split barrel.
Throughout these views similar parts are marked with like letters of reference.
The bearing bracket is constructed out of a piece of sheet steel stamped out to
the required shape and then rolled to form a split barrel A. with lugs a, a, through
which locking bolts B, B, pass. In each end of this split barrel are placed steel
cups C, C preferably stamped out of sheet steel, to form the races for the balls.
These cups have flanges c, c which bear against the edges of the split barrel-
which are faced to ensure the cups being square with one another-and they are
locked in position by contracting the split barrel by means of the bolts B, B. On
the centre of the split barrel A is brazed a split collar D or its equivalent carrying
suitable sockets d, 'd, to receive the forward tubular members of the frame as shewn
by Figure 6 of the accompanying drawing. As a modification the sockets d, d may
be stamped up out of the split barrel A when it is in its flat form, as shewn by
Figure 7 of the accompanying drawing.
The crown of the back fork which is preferably constructed according to the
method described in our Patent No. 2660 of 1891 is attached to the split barrel A
by the bolts B, B, its forward end being thinned down to allow it to pass between
the lugs a, a, as shewn in fine dotted lines by Figure 1 of the accompanying
drawing. To prevent the cups C, C, from turning in the barrel A a small slot c¹ is
cut in the flange c of each, with which the forward end of the crown of the back
fork engages.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction herein before described and illustrated by the accom
panying drawing but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is ;-
1. The improved construction of bearing bracket for the pedal-crank axle
of a velocipede, as hereinbefore described and illustrated by the accompanying
drawing.
2. In a pedal-crank axle bracket for velocipedes, the combination of a split
barrel adapted to be contracted by two bolts passing through lugs formed on the
ends of the said barrel, and of steel cups fitted in the ends of the said barrel
and clamped therein by contracting the said barrel, as and for the purpose set
forth.
3. In a pedal-crank axle bracket for velocipedes, the combination of a split
barrel adapted to have its internal diameter contracted by two bolts passing through
lugs formed on the ends of the said barrel; of steel cups-forming the races for the
ball bearings-fitting in the ends of the said split barrel and adapted to be clamped
thereto by the contraction of the split barrel, and of sockets or their equivalents
formed in the split barrel or in a split collar or its equivalent fixed thereto
and adapted to receive the tubular members of the frame as and for the purpose set
forth.
4. In a pedal-crank axle bracket for velocipedes, the combination of a split
barrel having lugs fitted with bolts or screws for the purpose of contracting its
internal diameter, and adapted to receive the crown of the back fork between the
said lugs as a means of attaching the said lugs to the pedal-crank axle bracket, of
cups for the ball bearings fitting in the ends of the split barrel and clamped thereto
by contracting its internal diameter, and of the sockets or their equivalents formed
in the split barrel or in a split collar or its equivalent adapted to be fixed thereto
as for the purpose set forth.
