Brakes for Cycles.
GEORGE JOHN BECK, 68, Mill Road, Lincoln, Shoemaker, HENRY KEYWORTH,
7, Foster Street, Lincoln, Lamp Inspector, do hereby declare the nature of this
invention to be as follows:-
The brake concists of metal frame fitted with blocks arranged to move back-
ward & forward, within forks of back wheel, and acts on both sides of rim, and
are supplied with springs, which keep them normally away from rim. Suitable
connection of flexible wire cord, or small link chain is arranged to transmit
the power from handle bar lever to the brake, pulley and roller clips guide
the chain or cord under the bottom tube, under the head between front forks,
and up front of head to lever.

GEORGE JOHN BECK, of 68, Mill Road, Lincoln, Shoemaker, and HENRY
KEYWORTH, of 7, Foster Street, Lincoln, Lamp Inspector, 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:-
-
On the handle-bar of a bicycle A, Fig. 1, (see drawing herewith) is attached a
moveable lever B which is attached to the handle-bar by means of a clip & pin
at its end Fig. 2 a little distance from which is the elbow or check-lever R
fixed by a clip on the handle-bar and the other, end working on a pin screwed
into the brake lever B, which has attached to it the chain C which passing
round the crown-clip pully D passes between the forks by means of the guide E
and then through the guide-clip F and is attached to the bell-crank G to the
lower crank of which at H is attached a connecting-rod J the other end of
which is fastened to the brake shoe K. The brake-shoe K is kept in its normal
position, that is, off the rim of the wheel by means of the spiral-spring at L
bearing on a thrust-block M which is fixed in between the chain stay the one
end and pushing the brake-shoe K in the other direction. The guide-rod N on
the brake shoe K passing down the centre of this spiral-spring penetrates a
guide-block M on the bicycle thus forming a guide for the brake-shoe K. This
brake-shoe K bears at will against the inside of the metal rim of the hind-wheel
on both sides of the spokes. The brake-shoe K, is brought to bear upon the rim

page_text: of the wheel by means of raising the brake-lever B on the handle-bar A. The
desired tension of the chain C which connects the lever B with the brake-
shoe K, is obtained by the chain adjuster M consisting of screw schackle as
shown and guide pulley 1) at crown clip. On the brake-shoe K are the brake-
blocks which are fastened to the brake-shoe K by means of screws penetrating
the side of the brake shoe K, and thus attaching the blocks to the brake-shoe K,
or by other suitable methods.
Having now particularly described and ascertained the nature of our said
invention & in what manner the same is to be performed, we declare that
what we claim is:-
The chain-adjuster M, with the connecting chain C, with the crown-clip D,
with the clip-guide F, with the clip-bell-crank G, H and the connecting-rod J,
fastened to the brake-shoe K. The brake-blocks & the guide-rod L actuated by
the spiral-spring thereon operating against the thrust-block M which also acts
as the guide of said guide-rod.
For this invention we claim that the novelty lies in the general arrange-
ments connected with this method for arresting the progress of a bicycle by
means of bringing the brake to bear on the metal-rim of the hind wheel of
a bicycle.
