PROVISIONAL SPECIFICATION.
Friction Brakes for Cycles and the like.
I GEORGE JOHNSON Cycle Agent Hill Top near Eastwood in the County of
Nottingham do hereby declare the nature of this invention to be as follows:-
In a brake used for the stoppage of cycles and the like by means of friction
caused at A and B on drawing.
Figure C which is termed the bottom bracket is a fixture and Figure D is a
revolving axle passing through C and Figure A. is a revolving wheel which is
termed the chain wheel and is keyed on to Figure D so that by bringing Figure A
and B together by means of the lever E will cause sufficient friction for stopping
machine.
At Figures H and I are projections or webs in order to keep Figure E in proper
position and Figure E which is termed a lever is admitted between the said
projections or webs by means of the two slots J in lever marked E.
The lever E has two wedge shaped projections and by slightly pulling over the
lever causes the rods K and Figure B to be pushed forward on A, and the springs
on rods K bring them back again when the lever is let go.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
declare is-
1. The tapered or wedge shaped boss inside of chain wheel marked A.
2. The ring which is tapered inside to suit A aud marked B also the rods which
are attached to B and marked K.
3. Projections marked F and G which are fixtures on both sides of bracket C
which have holes to suit rods K.
4. Lever or pusher marked E and working between the projections or webs H
and I on drawing.

same is to be performed, to be particularly described and ascertained in and by
the following statement :-
In a brake used for the stoppage of cycles and the like caused by friction at A
and B on drawing.
Figure C which is termed the bottom bracket is a fixture, and Figure D is a
revolving axle passing through Figure C, and Figure A is a revolving wheel which
is termed the chain wheel and is keyed on to Figure D so that by bringing
Figure A and B together by means of the lever E will cause sufficient friction for
stopping machine.
Figure B bas two rods or bars which pass through Figures F and G on both
sides of bracket, and in the space between Figures F and G is a spring in order to
bring back Figure B from Figure A when brake is not required.
At Figures H and I are projections or webs in order to keep Figure E in proper
position, and Figure E which is termed a lever is admitted between the said
projections or webs by means of the two slots at J in lever E.

page_text: The lever E has two wedge shaped projections and by slightly pulling over the
lever causes the rods K and Figure B to be pushed forward on A, and the springs
on rods K bring them back again when the lever is let go.
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 :-
1. The tapered or wedge shaped boss inside of chain wheel marked A on
drawing.
2. The ring which is tapered inside to suit A. and marked B on drawing and also
the rods which are attached to B and marked K.
3. The lever or pusher marked E and working between the projections or webs
on bracket marked I on drawing, which causes the brake to come into use.
Dated this 6th day of June A.D. 1893.
