Improvements in Brake Mechanism for Cycles, applicable also to
similar purposes.
I, JAMES CALCOTT of Thurlaston House Foleshill Road Coventry in the County of
Warwick Manufacturer do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in brake mechanism for cycles
applicable also to similar purposes by which also the mechanism is secured against
concussion and exposure to dust and the like and is maintained in good condition and
working order with little or no trouble.
My brake is operated with a handle adjacent to the steering handle and is hung in
the usual manner to operate the rod or plunger leading to the brake block and this
rod is also adjustable in a tube leading towards the brake. Now according to my
invention I carry the tube in which the rod is adjustable right down to the back of
the brake block and it enters the socket on the back of the brake block and is secured
by a cross screw in that position. This tube works up and down in a bracket secured
to the crown of the steering forks which is formed with a socket or long sleeve for
this purpose or this sleeve may be in two parts the upper piece being merely a
ferrule. The lower portion of the tube connected to the brake block and immediately
above the bracket has a slot and the spring for moderating the brake in its normal
position is mounted inside the tube so as to be entirely out of sight and protected.
The upper portion of the spring is secured by a cross pin to the tube through the
ferrule or bracket and the beforementioned slot allows the tube to slide while the
spring is compressed and acts with freedom.

Improvements in Brake Mechanism for Cycles, applicable also to
similar purposes.
I, JAMES CALCOTT, of Thurlaston House, Foleshill Road, Coventry, in the County
of Warwick, Manufacturer, do hereby declare the nature of my said 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 improvements in brake mechanism for cycles
applicable also to similar purposes, by which also the mechanism is secured against

page_text: concussion and exposure to dust and the like and is maintained in good condition and
working order with little or no trouble.
My brake is operated with a handle adjacent to the steering handle and is hung in
the usual manner to operate the rod or plunger leading to the brake block and this
rod is also adjustable in a tube leading towards the brake. Now according to my
invention I carry the tube in which the rod is adjustable right down to the back of
the brake block and it enters the socket on the back of the brake block and is
secured by a cross screw in that position. The tube works in a bracket secured to the
crown of the fork and has a head with a long sleeve in which the tube slides or this
sleeve may be in two parts the upper piece being merely a ferrule. The lower
portion of the tube connected to the brake block and immediately about the bracket
has a slot and the spring for maintaining the brake in its normal position is mounted
inside the tube so as to be entirely out of sight and protected. The upper portion
of the spring is secured by a cross pin to the tube and the lower portion is held by a
cross pin through the ferrule or bracket and the before-mentioned slot allows the
tube to slide while the spring is compressed and acts with freedom.
In order that my invention may be more clearly understood and easily carried into
practical effect I have appended hereunto two double sized sheets of drawings upon
which I have shown examples of my improved brake.
Figure 1 is a front elevation showing my brake fixed in position.
Figure 2 is a part sectional side elevation of Figure 1.
Figure 3 is a side elevation of Figure 1.
Figure 4 is a front elevation showing a modification of my brake.
Figure 5 is a side elevation of Figure 4.
In carrying my invention into practice I connect the brake lever L to the plunger
rod R in the usual manner. This rod fits inside the tube T at the top end of which
I fix the lug piece and into this lug piece I fit the eye piece through which the
rod R passes. This eye piece is provided with the screwed projection on to which
the nut t'fits for tightening the eye piece on to the rod, thus firmly securing it in
the interior of the tube. The bottom portion of this tube T fits or slides into the
sleeve S which sleeve is attached to the crown W of the cycle by the bracket C which
clips the centre portion. The opposite end e¹ of this bracket is provided with a hole
to which the top end of the front mudguard may be secured. On the end 5 of the
tube T which protrudes through the sleeve I attach the brake block K by the screwed
pink and in order to maintain this brake block in its normal position I insert the
spring J in the interior of the tube entirely out of sight and protected from dust and
dirt and the like. The top end of this spring bears against the cross screw or pin 8'
or its equivalent or may be secured by this pin to the tube, and the bottom end rests
upon the cross screw or pin 82 which passes through the sleeve and through the tube,
the slot or opening & being formed on either side of the tube to allow it free action
to move up and down when operating the brake.
In the modification as shown at Figures 4 and 5 I form the sleeve S shorter and
mount the ferrule F on the top of this sleeve. The bottom end of the spring is
secured by the cross screw or pin to this ferrule, a slot being formed on either side of
the tube as before mentioned.
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:-
CLAIMS.
First. The improvements in the brake mechanism for cycles applicable also to
other purposes consisting essentially of the tube such as T in which the plunger rod
such as R or its equivalent is secured, the said tube working up and down in the
sleeve such as S or its equivalent and held in its normal position by a spring fixed in
the interior in the manner and for the purpose substantially as hereinbefore described
and as shown upon the accompanying sheets of drawings.

page_text: Second. In a velocipede brake enclosing the spring for keeping the brake block in
its normal position in the interior of the tube T or its equivalent and operating the
same in the manner substantially as hereinbefore described and as shown upon the
accompanying sheets of drawings.
