Improvements in or relating to Brakes for Cycles and other Light
Vehicles.
I, HERBERT HENRY GREEN, of 16, Pool Street, Wolverhampton, in the County
of Stafford, Cycle Fittings Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object simple and efficient means for use in locking
a brake upon or against the wheel of a cycle or other light vehicle, more especially
for the purpose of preventing the vehicle from being surreptitiously removed
when left standing.
According to this invention, a latch or lock is rigidly fixed to the framing of
the vehicle, such as to the steering socket of a cycle, and a portion of the brake
mechanism, such as the vertical rod to which the spoon or corresponding part of
the brake is directly fixed, passes through the latch or lock case or through other
guide which is in suitable position in relation to the latch or lock. When the
brake rod has been pressed down, or the brake mechanism moved, to an extent
which ensures that the brake is "hard on," a bolt within the latch or lock case
may be allowed, or made, to engage with a notch formed in the brake rod; or with
an opening formed through the side of the same when the rod is hollow, as usual,
or with other portion of the brake mechanism, as the case may be. It is preferred
to cause the engagement of the bolt with the rod, or other portion of the brake
mechanism, by an automatic action due to the pressure of a spring at the back of
the bolt when the bolt is free to move forward; and in this case, in order to pre-
vent the brake being accidentally locked when“ on," the latch bolt is normally
held back by means of a spring catch which is provided with a portion which
projects slightly through one face of the case and by pressing upon which the
latch bolt becomes released from the catch. When it is desired to unlock the
brake, the bolt is of course moved back by means of a key; and this may consist,
conveniently, of a short lever having studs thereon which engage with holes
formed in the exposed outer face of a short journal of the bolt which turns within
a hole formed through the side of the case. "If the bolt is not pressed into engage-

Vehicles.
I, HERBERT HENRY GREEN, of 10, Pool Street, Wolverhampton, in the County
of Stafford, Cycle Fittings Manufacturer, 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:--
This invention has for its object simple and efficient means for use in locking
a brake upon or against the wheel or brake drum of a cycle or other light vehicle,
more especially for the purpose of preventing the vehicle from being surrepti-
tiously removed when left standing.
According to this invention, a latch or lock is rigidly fixed to the framing of the
vehicle, such as to the steering socket of a cycle, and a portion of the brake
mechanism, such as the vertical rod to which the spoon or corresponding part of
the brake is directly fixed, passes through the latch or lock case or through other
guide which is in suitable position in relation to the latch or lock. When the
brake rod has been pressed down, or the brake mechanism moved, to an extent
which ensures that the brake is "hard on," a bolt within the latch or lock case may
be allowed, or made, to engage with a notch formed in the brake rod, or with
an opening formed through the side of the same when the rod is hollow, as usual,
or with other portion of the brake mechanism as the case may be. It is preferred to
cause the engagement of the bolt with the rod, or other portion of the brake
mechanism, by an automatic action due to the pressure of a spring at the back of
the bolt, when the bolt is free to move forward; and in this case, in order to prevent
the brake being accidentally locked when "on," the latch bolt is, preferably,
normally held back, by means of a spring catch which is provided with a portion
which projects slightly through one face of the case and by pressing upon which
the latch bolt becomes released from the catch. When it is desired to unlock.the
brake, the bolt is, of course, moved back by means of a key or handle; and this
may consist, conveniently, of a short lever having studs thereon which engage with
holes formed in the exposed outer face of a short journal of the bolt which turns
within a hole formed through the side of the case, or (if it is not required, to guard
against surreptitious removal of the vehicle) the. key or handle may consist of a
lever permanently fixed to the journal of the bolt. If the bolt is not pressed into
engagement with the rod, or other portion of the brake mechanism, by means of
a spring, it must, of course, be moved into such engagement by a key or handle,
as well as unlocked thereby.
In order that the invention may be clearly understood, I will proceed to describe,
with reference to the accompanying drawings, and by way of example, an appli-
cation of the same in the case of an ordinary plunger brake of a safety-bicycle.
Figure 1 is a plan of the lock case shewn as rigidly connected to the steering socket
of the bicycle. Figure 2 is an underside view of the parts shewn by Figure 1, the
plate of the lock case being removed to expose the interior mechanism. Figure 3
is a section taken on line x of Figure 1, and shews also the brake block and a
portion of the brake rod, in their locked position. Figure 4 is a corresponding
view to Figure 3, but shews the brake block and rod unlocked and in their. raised
position. Figure 5 is a section on line yy of Figure 1, and shews the bolt in its
unlatched position. Figure 6 is a view shewing the outer end of the, bolt and a
spring catch by means of which it is held in its unlatched position, the parts being
shewn in the position they assume when the bolt is latched! In this view, also,
a short length both of the upper and lower plate of the lock case is shewn. Figure 7
is a corresponding view to. Figure 6, but shews the bolt to have been moved back

page_text: just sufficiently to bring a bevelled face. thereof immediately over and against a
bevelled face of tho; catch. Figure 8. is a corresponding view to Figure 6, but
shews the bolt to be retained by the catch in its backward or unlatched position;
and Figure 9 is a side view of the inner end of the key or lever used in unlocking
the bolt

?
The lock case A is rigidly connected to the steering socket B by means of the
clip C, one side of which is formed' with the case. The lower end of the brake
rod D is guided through a hole a formed through the upper and lower plates of the
lock case. The brake block is normally held, as usual, clear of the wheel tyre,
by means of a spring b which is interposed between the upper plate of the lock case
and a collar c which is fixed to the brake rod, or in other convenient manner. A
bolt'd within the case A has journals eel which are a turning fit within correspond-
ing holes formed through the upper and lower plates of the case. This bolt 18
formed as an arm or lever and has a head f projecting from its side which is
towards the brake rod. This bolt is shewn. by full lines, Figure 2, in its unlatched
position; and by broken lines in its latched position. The bolt is normally pressed
towards the brake rod by a spring h, and is normally held in its unlatched position
by means of a spring catch 3. A hole g is formed through the side of the brake
rod, in such position that when the brake is “hard on the opening is brought,
opposite to the bolt head f, with the result that, if the bolt is released from the
catch the head is immediately pressed into the hole by the action of the
spring h, and the brake thus locked upon the tyre. Holes are formed in the
journal e of the bolt, so that the bolt may be moved back to bring the head f
clear of the brake rod D, by means of a lever or key E which is provided with
short studs to engage with the holes h¹.
"
The catch by which the holt is normally held in its unlatched position is
formed with a square portion which is a sliding fit through the upper plate of
the lock case, and normally projects a short distance thereabove for convenience of
manipulation,, and with a shank k¹ which is a sliding fit through the lower plate
of the case. A bevelled shoulder projects sideways from the portion k of the
catch. A spiral spring m around the shank tends to, press the catch upwards
with the shoulder against the underside of the upper plate of the case. The outer
end n of the bolt d is bevelled the reverse way to the bevel of the shoulder 7, and
as the bolt is moved back, by the, key or lever, the face of the bevelled portion of the
bolt passes over and presses against the face of the bevelled portion of the shoulder /
and thus presses down, the catch.j, against the pressure of the spring m, until the
bolt has passed the catch, when the latter is pressed up again by the spring m and
thus comes in front of the bolt and maintains it in its unlatched position.
1
When it is desired to fasten the brake "hard on," the catch is pressed down to
release' the bolt, and thus when the brake rod has been moved down to bring the
brake block hard upon the tyre, and the opening in the rod thereby brought
opposite to the bolt head f, the bolt is simultaneously moved forwards by the
spring and the head f thus brought into, the opening g and the brake conse-
quently locked.
In cases in which it is not required to provide against the surreptitious removal
of a vehicle, the key or lever by which the bolt is moved back to unlock the brake
may be permanently connected with the bolt.
It is not essential, though it is very much preferred, to use a catch for holding
the bolt in its unlocked position. If, however, such a catch is not used, the brake
will always become locked, if the bolt is self-latching, whenever the brake is put
hard on.
Any convenient form of locking mechanism may be used, and in lieu of a key
having studs for engagement with holes formed in an exposed portion of the bolt,
the bolt may be moved by a key which is inserted for such purpose into the lock
case.
The bolt need not, of course, be self-latching, but if it is not so it must be moved
out as well as drawn in by means of a key or handle.
