ISHMAEL CARTWRIGHT 9 Talism Street Llandudno Carnarvonshire Blacksmith
do hereby declare the nature of this invention to be as follows:-
A noiseless safety lever brake adapted for heavy carts to work on naves of both
wheels instead of on tyres which consists of hanging blocks hinged to body
2 connecting rods roled bar with props & eyes fixel to bed of axle powerful lever to
work on bottom of shafts in a rack for the operator not to leave the side of the
horse.

ISHMAEL CARTWRIGHT.
I, ISHMAEL CARTWRIGHT, of 9, Talisin Street, Llandudno, in the County of Carnarvon,
Blacksmith, 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 stateinent :-
My invention has for its object a noiseless safety lever brake adapted for heavy
vehicles which is easily and quickly applied and does not make any of the objectionable
noises so common with brakes when applied to the wheel tyre; it has also a tendency
to lift the weight of the load from the horse's back when descending a hill,
thus avoiding the necessity of moving the weight of the load backwards and
forwards.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings showing my
improved brake applied to a two-wheeled vehicle.
Figure 1 is a side elevation of a cart showing my improved brake attached
thereto.
Figure 2 is an underside plan view of Figure 1.
In carrying my invention into practice I attach the top part of the two hanging
hinges A and A' to the sides of the body of the cart C; the bottom part of these hinges
carry or support the brake blocks B and B', which are secured thereto by the nuts
and bolts 2 and 6. These blocks may be made of wood or other suitable material,
but I prefer to use poplar wood. The spring S2 is provided for keeping the blocks in
position when not in use. I then pivot the bar D to the axle C by means of the eve
pieces E which are bolted or otherwise secured to the axle. Formed out of or attached
to this bar are three projections or prongs d', d and d³; the two end ones d' and d
are connected to the bottom of that part of the hinge which supports the brake blocks
by means of the connecting rods F and F', and the centre one is connected to the

page_text: bar H by the connecting rod 1. One end of the bar II is pivotted at 2 on the
underside of the shafts S and S to the plate 3, which is bolted to the side of
the shaft S or to any other convenient part of the vehicle, and to the other end of
this har I attach the toothed wheel which works in the rack K, fixed on the
underside of the shaft S¹. This toothed wheel is supported in the bracket h³ and
attached to it on the outer side are the handles h*.
To apply the brake the handles are turned in the direction of the shafts, thus
moving the bar H on its pivot and consequently the har D with its connecting rods
into the position as shown at Figure 2, thereby drawing the swinging brake blocks
tightly around the nave of each wheel. When the bar is moved back again the
spring S2 forces the brake blocks out of contact with the nave of the wheel into its
normal position.
It will be quite evident that other means may be used for operating the swinging
brake blocks and that they may be operated from the back of the vehicle. I may also
hinge the brake blocks in front of the wheel naves.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
First. The improved brakes for vehicles consisting essentially of the brake block
hinged or pivotted to the side of the vehicles and operated by suitable connecting
rods in the manner substantially as hereinbefore described and as shown upon the
accompanying sheet of drawings.
Second. Hinging or pivotting the brake blocks to the sides of a vehicle so that
when operated by the connecting rods they bind upon the naves of the wheels in the
manner substantially as hereinbefore described and as shown upon the accompanying
sheet of drawings.
