PROVISIONAL SPECIFICATION.
Improvements in and connected with Brakes for Use on the Wheels
of Cycles, Motor Cars, and other Vehicles.
We REUBEN CHAMBERS and FREDERICK HAWLEY both of Vauxall Works
Dartmouth Street Birmingham in the County of Warwick, Mechanical Engineers
do hereby declare the nature of this invention to be as follows:-
This invention consists in the improvements in and connected with the brakes,
steering-rods and brake blocks of cycles, motor-cars and other vehicles
hereinafter described under two parts.
as
The first part of our invention has for its object the locking of a brake over the
tyre of a cycle wheel, a motor-car wheel, or over the tyre of the wheel of any other
vehicle the brake of which is actuated by a brake-rod similar or equivalent to the
brake-rod of a cycle.
We provide a clipping-band made from flexible steel or from other suitable
material bent into the required shape to clip the head of bicycle near to its
brake-rod, or to clip any part of a motor-car or other vehicle near to its brake-rod;
each back-end of the clipping band is by preference bent over a solid part and
secured thereto by suitable mechanical means, and each of such solid back ends is
pierced to receive an adjusting-pin; we next provide an adjusting-pin screwed to
take into a thread formed in one of the solid parts of back end of clip, we pass
the adjusting-screw through one of the solid back ends and screw it into the other
solid part of hack end of clipping-ring and thereby draw the back ends close
together when required. At the front part of the clipping-ring we so pierce the
ring or band as to be enabled to pick up the front end of piercing and we then bend
outwards the detached picked up part so as to form a projecting cheek, a second
piercing is made and picked up to form the second cheek, thus presenting a pair
of cheeks suitable to receive the cramp as hereinafter described, the cheeks pierced
in the manner hereinbefore described are suitable for use in connection with cycles
but when making the clipping-ring for use in connection with motor-cars or other
vehicles we prefer in some cases to produce the ring or band and its projecting
cheeks by a stamping process or by casting or other equivalent mean.
We next provide the cramp which consists of a piece of metal or material the
front end of which is formed semi-circular or of a suitable shape to fit against the
brake bar so as to engage with the said brake-bar and thereby lock the brake-block
over the tyre of wheel and also lock the steering-bar and the brake-bar thus
preventing the wheel from moving either way that is to say preventing it from
moving either to the right or to the left and also preventing it from revolving.
The back-end of the cramp is formed of a suitable shape to make a hinge-joint,
we pierce the hinge-end of cramp and also the cheeks of clipping-band and pass
an axial-pin through one cheek of clipping-band, thence through the back-end of
cramp and out through the other cheek of clipping-band and so mount the cramp
within the cheeks of clipping-band in such a manner that the cramp can be
radiated between the cheek bearings.

page_text: We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is constructed and used.

attached and in action.
Fig. 2 represents a back view of brake holder curved into its fixed position.
Fig. 3 represents a front view of brake holder opened out
Fig. 4 represents a side view of brake holder in position but out of action.
Fig. 5 represents a plan of Figure 2.
Fig. 6 represents the application to a motor-car or other vehicle brake.
Fig. 7 represents an Isometrical view of holder as made of non-flexible
material.
Fig. 8 represents a section on line AB of fibre brake-block Figure 9, with
brake-rod attached.
Fig. 9 represents a plan of brake-block Figure 8.
In carrying out our invention we provide a clipping-band a made from flexible
steel or other suitable material bent from the flat as shewn at Figure 3 into the
required shape shewn at Figure 5 suitable to clip the head of bicycle as shewn at
Figure 4 near to the bicycle brake-rod as shown at Figure 1
b
Each back end of the clipping band a is by preference bent over a solid part
and secured thereto by bending over the ends and rivetting the beuf-over part as
hewn at c or by other suitable mechanical means, each solid part b is pierced to
receive an adjusting pin.
We next provide an adjusting pin secured into a threaded hole formed in one
of the solid back ends b, we pass the screwed end of adjusting screw through
the passage in one of the solid parts b and screw it into the other solid part b and
thereby draw the back ends close together and so secure the clip to the head of
bicycle as shewn in enlarged view Figure 4 and as shewn in action at Figure 1.
At the front part of the band when in its flat position as shewn at Figure 3
we pierce it in such a manner as to be enabled to pick up the front end of the
piercing and bend outwards the detached part to form a projecting cheek e.
A second piercing is made and picked up to form the second cheek f thus
presenting a pair of cheeks and f suitable to receive the cramp hereinafter
described.
We next provide the cramp which consists of a piece of metal or material the
front end h of which is formed semi-circular or of a suitable shape to fit against
the brake-jar j and thereby lock the brake-block over the tyre of wheel at the
same time also locking the brake-bar from turning within the handle-bar bracket,
consequently indirectly locking the steering-bar and thus preventing the wheel
from revolving or moving either to the right or left.
The back end of the cramp is formed of a suitable shape to make a hinged joint
and we pierce such hinged end of cramp also the cheeks e and f of clipping-band
and the back end of cramp and so mount the cramp within the cheeks e and f of
clipping-band in such a manner that the cramp g can be radiated between its
cheek bearings e and f.
Instead of making the clipping-band from flexible material we prefer in some
cases to produce the band and its projecting cheeks by a stamping process or by
other equivalent means as shewn at Figure 7; in such cases cheeks b₁ are provided
as equivalents to the solid parts of Figure 5 and the band is formed of two
pieces hinged together as shewn at n Figure 7. The cheeks e' fl corresponding
with the checks ef of Figure 5 and the cramp gl corresponding with the cramp 9
shewn at Figure 2 and it will be readily understood that the band as shewn at
Figure 7 can be radiated on its hinged joint n, placed over the lock head and
secured thereto by means of the adjusting pin d in a precisely similar manner to
the flexible band as shewn at Figure 5. The user of a bicycle fitted with our
brake lock or cramp of the design shewn at Figure 5 or of the design shewn at
Figure 7 would after dismounting lower the brake-rod j and its brake-lock k and
secure such brake-block k over the wheel tyre and after such lowering of the
