PROVISIONAL SPECIFICATION.
A New or Improved Bearing Bracket for the Back Wheel of
Velocipedes.
I ALFRED HAWKIN, of 79, Holgate Road, York, Gentleman, do hereby
declare the nature of this invention to be as follows:-
My invention relates to a new or improved bearing bracket for the back wheel
of velocipedes and refers more particularly to that class of velocipedes known as
rear driving safeties. The object of my invention is to enable the back wheel to be
removed much more quickly than is possible with brackets of ordinary construction,
and it not being necessary to detach the chain, the latter can be made without a
detachable link which is always a weak point.
In carrying my invention into practice I form the slot in the bearing bracket in
the reverse direction, that is, the opening of the said slot is towards the front of
the machine, said slot extending towards the rear of the same, it will thus be seen
that the rear wheel is put in, or removed from the front instead of at the back as is
the case with all existing machines, the wheel being adjusted by eyebolts and nuts
in the ordinary manner.
In order to dispense with the detachable link in the chain it is necessary that
the back stays of the frame should be detachable at the top as the majority of them
are now made.

COMPLETE SPECIFICATION.
A New or Improved Bearing Bracket for the Back Wheel of
Velocipedes.
I ALFRED HAWKIN of 79 Holgate Road York Gentleman 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 a new or improved bearing bracket for the back wheel of
velocipedes and refers more particularly to that class of velocipedes known as rear
driving safeties.
The object of my invention is to enable the back wheel to be removed much
more quickly than is possible with brackets of ordinary construction, and it not
being necessary to detach the chain, the latter can be made without a detachable
link which is always a weak point.
In carrying my invention into practice I form the slot in the bearing bracket in
the reverse direction, that is, the opening of the said slot is towards the front of
the machine, said slot extending towards the rear of the same, it will thus be seen
that the rear wheel is put in, or removed from the front instead of at the back as
is the case with all existing machines, the wheel being adjusted by eyebolts and
nuts in the ordinary manner. In order to dispeuse with the detachable link in the
chain it is necessary that the back stays of the frame should be detachable at the
top as the majority of them are now made.

page_text: In order that my invention may be more fully understood I will now proceed to
describe same with reference to the accompanying sheet of drawings, in which
Fig. 1 is a side elevation of the bearing bracket showing hub and axle of wheel
in position,
Fig. 2 is an end view of part of a frame showing detachable stays,
Fig. 3 is a side view of the bearing bracket, and
Fig. 4 a side view of a bracket of ordinary construction.
Like letters of reference indicate corresponding parts throughout the drawings.
In Figs. I and 3 of the drawings it will be readily seen that my invention
consists in forming the slot in the bearing bracket A in the reverse direction,
that is, the entrance a being towards the front of the machine (Fig. 3) instead of at
the rear of same (Fig. 4.) the axle d of the wheel entering from the front at a and
being adjusted within the slot b by means of the eye-bolts i and nuts n one on either
side of the frame. When it is required to take out the back wheel for cleaning or
other purposes the nut n is removed which allows the wheel to be drawn towards
the opening a and passing out at that point, the chain being then slipped over
the gear wheel mounted on the hub, and the wheel removed from the machine,
without a detachable link in the chain being necessary as is the case with existing
machines.
If it is required to remove the chain from the machine altogether it is essential
that back stays c should be detachable at the top as shown at Fig. 2. so that the
chain can be passed along the stay c and off at the top m when the bolt m' is
removed.
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
The improved bearing bracket for the back wheels of velocipedes, arranged and
constructed substantially as herein described and shown with reference to Figs. 1
and 3 of the accompanying drawing, and for the purpose set forth.
