AMBROSE ARCHER of the City of Liverpool "IMPROVEMENTS IN BRAKES FOR
WHEELED CARRIAGES"
This Invention is mainly applicable to common Road Carriages and Tramway
Cars.
To apply the Invention to say a Common "Stiff Cart" such as is used for the
Conveyance of Coal or other heavy substances-A rocking shaft is mounted
parallel to the axletree the ends of which extend over the inner ends of the naves
of the wheels. The extremities of this transverse rocking shaft are formed or
fitted with T ends one of the limbs of which may be sufficiently extended to form
the operating lover or the actuating lever bar may spring from any part of the
cross head found most convenient for adapting it to the body of the Carriage-
The inner ends of the naves of the wheels are by preference fitted with metal
zones rigidly attached thereto the peripheries of which may be formed with a
gutter to receive a jointed or clastic metal band; the ends of which are jointed to
the opposite ends of the T head on the rocking shaft. In some cases it is preferred
to line the griping garters or bands with small blocks of timber to prevent jar;
And they may be constructed with screwed rod and so forth at one end to regulato
the length thereof.
In some cases it may be advisable to corrugato groove or flute the peripheries of
the rings which encompass the inner ends the inner ends of the naves of the wheels
and forming the inner surfaces of the griping bands or the blocks fitting them so
as to take unto the indentations thereby enlarging the surface to increase the
friction.
When this Invention is applied to, say, a pair of Carriage wheels the body of
which is mounted upon springs-the several parts may be arranged in the same
way by merely mounting the transverse rocking shaft upon the axletree so as to
be free of the springs.

page_text: In applying the Invention to Vehicles having axles which revolve with the
wheels as in the case of Tramway cars, On the revolving axle a friction pulley is
(or pulleys are) secured the Peripheries of which may be plain guttered or
grooved in the same way as the zones secured to the naves of the wheels before
described. A smooth pinion or small pulley is formed on the side of the friction
wheel staked on to the revolving axle or it may be an independent wheel (or
wheels) fixed on any convenient part of the revolving axle which supports a guide
frame, the upper end of which works in a glan secured to the body of the Carriage
forming a telescope joint to allow the carriage body to rise and fall by which
arrangement the fulcrum of the rocking shaft of the brake which is mounted
thereon to be always equidistant from the axle. The rocking shaft is mounted in
suitable plumber blocks attached to the vertical guide frame one two or more of
the friction pulleys with their adjuncts may be applied to each axle and when
applied to both axles the brake levers thereon may be connected together by link
rods so as to operate simultaneously in which case a windlass or wheel and pinion
motion or other convenient mechanical arrangement may be applied to the
actuating levers.
In place of connecting the vertical frame carrying the rocking shaft with the
body of the carriage-by-the-telescope-joint-referred to the top of the frume may ba
kept in position by a rod (or rods)-jointed-to-the-frame-and-the-Carriage_body_or_
other convenient position
This Invention is also applicable to vehicles having cranked axles by forming
the fulcrums on the sides of the crank arms and operating the griping garters
through link rods.
In some cases it may be desirable to arrange the cross-levers-on-the-ends-of-the-
rocking shaft so that one end of the friction garter shall be fixed and when thus
arranged be contracted or drawn on to the friction wheel or zone by one end only.

AMBROSE ARCHER, of the City of Liverpool "IMPROVEMENTS IN BRAKES FOR
WHEELED CARRIAGES."
This my said Invention is mainly applicable to Common Road Carts, Carriages
and Tram Cars.
To apply this my said Invention to say, a common "Stiff Cart" such as is used
for the conveyance of Coal or other heavy substances I mount a rocking shaft
parallel to the axletree, the ends of which extend over the inner ends of the naves
of the wheels. The extremities of this transverse rocking shaft are formed or
fitted with T ends, one of the limbs of which may be sufficiently extended to form
the operating lever, or the actuating lever-bar, may spring from any part of the
cross head found most convenient for adapting it to the body of the Carriage. The
inner ends of the naves of the wheels I by preference fit with metal. zones rigidly
attached thereto, the peripheries of which may be formed with a gutter to receive
a jointed or elastic metal band, the ends of which are jointed to the opposite ends
of the T heads on the rocking shaft. In some cases I preferred to line the griping
garters or bands with small blocks of timber to prevent jar And they may be
constructed with a screwed rod and so forth at one end to regulate the length
thereof
In some cases it may be advisable to corrugate, groove or flute the peripheries
of the rings which encompass the inner ends of the naves of the wheels and forming
the inner surfaces of the griping bands, or the blocks filling them so as to take
unto the Grooves thereby enlarging the surface to increase the friction.
When this iny said Invention is applied to say a pair of Carriage wheels, the
body of which Carriage is mounted upon springs, the several parts may be arranged
in the same way by merely mounting the transverse rocking-shaft upon the
axletree, so as to be free of the springs.
In applying the Invention to vehicles having axles which revolve with the
wheels, as in the case of Tramway Cars. On each revolving axlo I mount a
friction pulley (or pullies) which are keyed thereto the peripheries of which friction
pullies may be plain guttered or grooved in the same way as the zones secured to
the naves of the wheels herein before described. A smooth pinion or small pulley
is formed on the side of the friction wheel staked on to the revolving axle, or it
may be an independent wheel (or wheels) fixed on any convenient part of the
revolving axle, which supports a guide frame the upper end of which works in a
glan secured to the body of the Carriage forming a telescope joint to allow the
Carriage body to rise and fall by which arrangement the fulcrum of the rocking
shaft of the brake which is mounted thereon to be always equadistant from the
axle. The rocking shaft is mounted in suitable plumber blocks, attached to the
vertical guide frame ono two or more of the friction pulleys with their adjuncts
may be applied to each axle and when applied to both axles the brake levers
thereon may be connected together by link rods so as to operate simultaneously in
which case a windlass or wheel and pinion motion or a screwed rod and revolving
nut or other convenient mechanical arrangement may be applied to the actuating
levers.
In place of connecting the vertical frame carrying the rocking shaft with the
body of the carriage by the telescope joint referred to the top of the frame may be
kept in position by a rod (or rods) jointed to the frame and the Carriage body or
other convenient position.
This my said Invention is also applicable to vehicles having cranked axles by

D. The cross or T ended lever to which is attached the ends of
E the gripping garter seen at figure 3 fitted internally with wooden blocks to
obviate jar and is jointed in the centre-but when a plain steel band is used the
joint can be avoided as the elasticity of the metal will be sufficient to allow it to
close upon
