PROVISIONAL SPECIFICATION.
Improvements in Brakes for Carts and other Vehicles, to Work
Automatically.
MICHAEL MOORE HOBSON Catchgate, Annfield Plain County of Durham,
Miller do hereby declare the nature of this invention to be as follows:-
The object of my invention is to cause existing brakes or add brakes to vehicles
to be worked by the motive power when necessary for instance the horse in a cart
to apply the brake automatically when going down a hill or when stopping the
yoke being in connection with the brake at the breeching. The power now used
in holding the vehicle back is conveyed to apply the brake by a lever or round a
pulley and thence to the brake. The brake leaves the wheel as soon
pressure is taken off the breeching.

Improvements in Brakes for Carts and other Vehicles, to Work
Automatically;
MICHAEL MOORE HOBSON Catchgate, Annfield Plain, Co. Durham, Miller 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:-
The object of my invention is to cause existing brakes or add brakes to vehicles
to be worked by the motive power when necessary for instance the horse in a cart
to apply the brake automatically when going down a hill or when stopping the yoke
being in connection with the brake at the breeching. The power now used in holding
the vehicle back is conveyed to apply the brake by a lever or round a pulley and
thence to the brake the brake leaves the wheel as soon as the pressure is taken off
the breeching.
I will describe my invention with reference to the accompanying drawings.
Fig. 1. shows part of a shaft or pole S with a lever A swung in the centre or
thereabouts one or more holes can be added to alter the power or travel to be
needed by the brake. The top of this lever to be made with a hook or eye to
attach the chain or strap of the breeching of the horses harness, the bottom of the
lever to be made with a hook or eye to suit a chain or rod to convey the power to
the brake. When the horse holds backward it pulls the lever back at the top
and draws it forward at the bottom, the power is thereby transmitted by tension
and can be conveyed round a pulley or pulleys or can be turned into a thrust by
another lever or levers, and a thrust can also be got direct from the eye E at the
top of lever. When the vehicle is to be put backward the lever A can be fastened
by a pin or wedge or by a plate B with a hinge or joint near the centre which can
D

page_text: be turned over behind the lever as shown to prevent the brake from being applied
to the wheel, or if the fixed hooks or eyes:as used now are in the shafts the chain
or strap may be removed to them. The brake leaves the wheel as soon as the
pressure is taken off the breeching either by the brakes construction or by a spring
or balance weight on the brake. In each Higure S shews part of a shaft or pole of
vehicle.
Fig. 2. shows where the 'back chain can be attached to the hook D and where
the trace can be attached to the hook C there are in this case two levers to form
a parallel motion, when the breeching is drawn attached to the hook E it pulls the
lever A forward at the bottom apply .the brake as .in Fig. 1. If the power is
transmitted by a stiff rod from the lever 'to the 'bråke the trace attached to C
works the lever in the opposite direction and presses the brake from the wheel, a
thrust can be applied at the top of lever the same as in Fig. 1. This arrangement
can be fixed to prevent the brake being applied to the wheel with pin or wedge or
by a stop B now in position to prevent its moving and can be turned over as shown
by dotted line 'to 'release the 'lever.
Fig. 3. shows another method where 'the trace assists in working the lever, the
draw hook C is attached to the breeching hook E by a plate through which the
'lever A passes as shown through 'hole the same size as lever but to work freely,
at the points G G the 'holes in F through which the back hook guide passes are
sufficiently long 'to give travel to the lever A 'the back 'hook guide HH keeps the
plate F in its place this is fastened by a pin if required to prevent the brake from
working.
Fig. 4. 1shows where the power to apply the brake is transmitted by a thrust
directly by a rod D fitted on the top, sides or bottom of shafts to move freely in
the guides G G and fitted with breeching hook or eye E and if required with
draw hook F the latter hook not necessarily at the end as shewn but on any part of
rod D, if this rod is on the top of shafts the back chain or band hook may be
attached to work horizontally with rod D or can be fixed by the side to the shaft
independent of D. Brahews a pin to prevent the rod from applying the brake
B may be put through D in any,part desirable. In the case of the thrust being the
most desirable way of conveying the power to brake, where none of the above
methods are practicable in any way, a tube may be passed over the shaft freely
and to this tube the breeching hook and drawn hook can be attached to the top
and the back hook if required. also, and the rod to convey the power to the brake
can be attached to any side of this tube.
Figs. 5 & 6. show where the lever and hooks can be in one piece or where they
can be closely jointed together at the top. B shews a stop which prevents the
lever from working and can be turned to allow 'to allow the lever to work. To
keep B in position a cavity in the shaft or small pins projecting above the shaft
may be put.
Fig. 7. shews where the lever instead of passing through or on one side can be
conveyed on each side of the shaft or pole either in one piece or two fastened
together at top and bottom, this arrangement is applicable to Figs. 1, 2, 5 & 6
which levers may be through the shaft or on one side.
Fig. 8. shows where the power from the 'breeching can 'be conveyed round a
pulley on or in the shaft or pole, by a chain or rope to the 'brake.
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 1
claim is :-
First. A lever A attached to S as herein before described and illustrated in the
accompanying drawings.
Second. A rod D attached to S as herein before described and illustrated in the
accompanying drawings.
Third. A tube attached to S as herein before described.

page_text: Fourth. A pulley P attached to S as herein before described and illustrated in
the accompanying drawings.
Fifth. A stop B attached to S as hereinbefore described and illustrated in the
accompanying drawings.
