Improvements relating to Cycle and like Brake Mechanism.
I, HERBERT BEESTON, of 44, Merridale Road, Wolverhampton, in the County
of Stafford, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows: :-
My invention has for its object the construction and arrangement of compact
and reliable cycle and like brake mechanisin that can be readily applied by the
action of back pedalling.
In the application of my invention to a chain driven cycle of the usual type,
I mount upon one of the cranks or the crank spindle, preferably on the side oppo-
site to the chain wheel, a cam plate or disc, and interpose clutch rollers between
the parts so that a rotary movement shall be imparted to the cam plate only
when a reverse or back pedalling effort is applied to the cranks.
The periphery of the cam plate abuts against a roller carried at the forward
end of a sliding bar supported by a bracket mounted upon the tubular framing
adjacent to the cycle bottom bracket. A projection from the said bar engages
and operates a rocking lever to the inner end of which is connected the cross-head
or attachment plate of the brake blocks which act upon the inner surface of the
rear wheel rim.
The movement of the rocking lever is transmitted to the brake blocks by means
of a pair of rods which are guided and supported by hinged brackets which can
be readily clumped in the required positions upon the ordinary D shaped tubular
chain stays of the cycle frame. A spring formed of suitable steel strip is mounted
upon the back or inner face of each hinged bracket which effects the withdrawal
or return of the brake blocks when the back pedalling effort is discontinued.
In a suitable barrel or casing arranged upon the bracket carrying the rocking
lever and the sliding bar, I dispose a spiral spring which is so connected with
the hercinbefore described cross-head as to prevent too sudden an application of
the brake blocks, and to permit of sufficient movement of the same when in
service to compensate for inequalities in the rim.
With my mechanism constructed and arranged as herein before described, an
effective brake or check may be applied to the machine at any position of the
cranks.

I, HERBERT BEESTON, of 44, Merridale Road, Wolverhampton, in the County
of Stafford, Mechanical Engineer, 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 has for its object the construction and arrangement of compact
and reliable cycle and like brake mechanism that can be readily applied by the
action of back pedalling.
Referring to the two accompanying sheets of explanatory drawings.
Figure 1 is an elevation, and Figure 2 a plan (with parts in section), repre-
senting the application of my invention to a bicycle of the usual chain driven
type.
Figure 3 is an end view of one of the brake rod guide and supporting brackets.
The same reference letters in the three views indicate the same parts.
I mount upon one of the cranks or on the crank spindle A, preferably on the
side opposite to the chain wheel B, a cam plate or disc, C and interpose clutch
rollers between the parts (in any ordinary manner) so that a rotary movement
shall be imparted to the cam plate only when a reverse driving or back pedalling
effort is applied to the cranks.
The periphery of the cam plate C abuts against a roller D carried at the for-
ward end of a sliding bar E supported by a bracket F mounted upon the tubular
framing adjacent to the cycle bottom bracket G. A projection from the said
bar E engages and operates a rocking lever H to the inner end of which is
connected the cross-head or attachment plate J of the brake blocks K K¹ which
act upon the inner surface of the rear wheel rim L.
The movement of the rocking lever H (on the application of a back-pedalling
effort to the cranks) is transmitted to the brake rods by means of a pair of
rods M M guided and supported by hinged brackets N N which can be readily
clamped in the required positions upon the ordinary D-shaped tubular chain
stays 00 of the cycle frame. The brake blocks K K' are mounted directly
upon the rear ends of the rods M M and are secured in the required positions
by the screws. A spring, as P and P², formed of suitable steel strip is
mounted upon the back or inner face of each hinged bracket N and N¹. The
said springs effect the withdrawal or return of the brake blocks K K' when the
back-pedalling effort is discontinued.
In an enclosing barrel or casing a secured to the cross-head J I dispose a spiral
spring R between the cross-head and a plunger or abutment plate S forming the
extremity of the cross-head connecting rod or stem T. The said spring R pre-
vents too sudden an application of the brake blocks, and permits of sufficient
movement of the same when in service to compensate for inequalities in the rim.
The projecting end of the casing Q is closed by the screwed head q.
With my mechanism constructed and arranged as herein before described, an
effective brake or check may be applied to the machine at any position of the
cranks.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:.
1. In cycle and like brake mechanism, means for transmitting a reverse driving

page_text: effort to brake blocks acting on a wheel rim, consisting in part of a sliding bar E
and a rocking lever H, substantially as described and as illustrated.
2. In cycle and like brake mechanism, the combination consisting of a cam
plate C having a clutch connection with the crank spindle A and a sliding bar E
having a roller 1 at its forward end and engaging one end of a rocking lever H,
the opposite end of the said rocking lever being connected with the brake
blocks K K', substantially as described and as illustrated.
3. In cycle and like brake mechanism, the combination consisting of a cross-
head J, rods M M having adjustable brake blocks K K' mounted thereon, rod
supporting hinged brackets N N¹ secured upon the stay tubes 0 0¹,
and springs P P respectively mounted upon the said brackets, substantially as
described and as illustrated.
4In cyclo and like brake mechanism, the combination with a rocking
lever H, and with a cross-head J connected with the brake blocks K K¹, of a con-
necting rod T, spring R, and spring enclosing casing Q, substantially as described
and as illustrated.
5 A back pedalling cycle brake comprised by the genera! combination of parts
constructed and arranged substantially as described and as illustrated.
