PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means for Attaching Bearings
to the Framework of Velocipedes.
I, GEORGE SINGER, of Alma Street, Coventry in the County of Warwick,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide bearings which are easily attachable
and detachable, thereby facilitating the construction of the machine, and such
bearings being also capable of being made more readily than the kind generally in
"use, and my invention consists of an improved method of and means for attaching
bearings to the framework of velocipedes, such for example as the bearing carrying
the crank spindle and pedals in the type of cycle known as the "Singer" Safety
or other velocipedes having a crank bearing of a similar kind.
In carrying out my invention in connection with a "Singer" Safety, I attach to
the end of the tube which usually carries the crank bearing, a bracket which is
fixed or brazed to the tube above referred to. The lower tubes from the back
part of the frame on either side of the driving wheel are fixed or brazed to the
lower end of this bracket.
The
Across the front face of the bracket a groove is formed preferably having a
radius of about one inch and through the groove say two holes are drilled about
inch in diameter, these being also preferably coned out on the inner side.
groove may be V shaped or of any shape which will tend to support the crank
bearing.
The central part of the bearing sleeve is made to fit into the transverse groove in
the bracket and to the sleeve is attached two studs which fit into the holes in the
bracket and by means of nuts on the other side, the sleeve is firmly held in
position; or screws may be introduced from the opposite side of the bracket
and screwed into the bearing sleeve which would be tapped for that purpose.
The strain exerted upon the cranks and the required resistance to the chain are
met in the most efficient manner and the bearing is prevented from twisting or
becoming loose, owing to the way in which the sleeve is attached to tlie bracket,
while other advantages will be attained owing to the facility of attaching and
detaching the bearing.

Improvements in the Method of and Means for Attaching Bearings
to the Framework of Velocipedes.
I, GEORGE SINGER, of Alma Street, Coventry, in the County of Warwick, Cycle
Manufacturer, 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 :-
The object of my invention is to provide bearings which are easily attachable
and detachable, thereby facilitating the construction of the machine, and such
bearings being also capable of being made more readily than the kind generally in
use, and my invention consists of an inproved method of and means for attaching

page_text: bearings to the framework of velocipedes, such for example as the bearing carrying
the crank spindle and pedals in the type of cycle known as the "Singer Safety or
other velocipedes having a crank bearing of a similar kind.
My invention will be best understood by describing same with reference to the
accompanying drawings.
Figure 1 is a rear elevation of an attachment of the bottom bracket to the
framework of velocipedes constructed according to my invention.
Figure 2 is a vertical section transversely to Figure 1 and on the line X Y of
the latter figure, of the same attachment.
Figure 3 shows the bearing sleeve with screwed studs corresponding with cone
shaped holes in the bracket.
Figure 4 shows in rear elevation the same attachment where the bracket does not
extend over the entire length of the bearing sleeve.
Figure 5 is a transverse sectional elevation of same through line X' Y¹ of
Figure 4.
Similar letters of reference refer to like parts in all the figures.
In carrying out my invention in connection with a Singer" Safety I attach
to the end of the tube A which usually carries, the crank bearing B, a
bracket C, which is fixed or brazed to the tube A above referred to. The
lower tubes D D from the back part of the frame on either side of the driving
wheel are fixed or brazed at D' D' to the lower end of this bracket C.
Across the front face of the bracket C a groove is formed preferably having
a radius of about one inch and through the groove two holes are drilled about
inch in diameter, these being also preferably coned out on the inner side.
The groove may be V shaped or of any shape which will tend to support the
crank bearing B.
The central part of the bearing sleeve B is made to fit into the transverse groove
in the bracket C, and to the sleeve B is attached two studs EE which fit
into the holes in the bracket C, and by means of muts F F on the other side
the sleeve B is firmly held in position; or screws may be introduced from the
opposite side of the bracket and screwed into the bearing sleeve which would
be tapped for that purpose.
The strain exeried upon the cranks and the required resistance to the chain
are met in the most efficient manner and the bearing is prevented from twisting
or becoming loose owing to the way in which the sleeve B is attached to the
bracket C, while other advantages will be attained owing to the facility of attaching
and detaching the bearing.
The bracket C would be made without having a bearing throughout its length
on the axle bearing sleeve B which is then supported by the studs alone going
through the correspondingly shaped holes in the bracket, but with the supporting
groove the attachment of the sleeve to the bracket is capable of resisting any strain
the machine could practically be subjected to.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is -
+ 3
First In velocipedes, attaching the sleeve axle bearing to a bracket on the
framework by studs and nuts substantially as set forth."
Second: The method of and means for attaching bearings to the framework
of velocipedes composed of the brackets C having holes therein to receive corre-
spondingly shaped studs E on the bearing sleeve B whereby the latter can be-
detached from the bracket C by the removal of nuts. F from the studs E or be
firmly secured to the bracket by the tightening up of the nuts F all substantially
as described and illustrated with reference to the accompanying drawings.
Third: In velocipedes, the particular construction and arrangement of the
bracket with a groove across the front face thereof corresponding in shape with
the axle bearing sleeve B and having holes therein for the reception of the studs E,

becoming loose substantially as herein before described and illustrated with reference
to the accompanying drawings.
