PROVISIONAL SPECIFICATION.
Improvements in Brakes or Skids for Lorries, Wagons, Carts, and
other Vehicles.
I, PETER DAWSON, of 99 Maxwell Street, Glasgow, in the County of Lanark,
North Britain, Distiller, do hereby declare the nature of this invention to
be as follows:-
This invention which relates to improvements in brakes or skids for lorries,
wagons, carts and other vehicles, has for its object to provide means whereby the
said brake or skid may be applied or taken off without stopping the vehicle and
at the same time when off is always in a position as to enable it to be instantly
applied.
In carrying out my said invention I form the slipper or shoe with its arm on
the outside in lieu of the inside as hitherto, the said arm being provided with one
or more holes; the said slipper or shoe is slightly curved and provided with
corrugations at its front end, as also two or more pins or studs on its front side
to which are attached the lower ends of two small rods or stays which are attached
at their top ends to the lower end of an upright rod or spindle which is so
formed as to keep clear of the cap of the wheel, and provided with a suitable
pivotted or other side acting and locking joint, and having its top end passing
up through a hole or opening in the lower end of a hollow cylinder or its
equivalent within which is mounted a spiral or other spring, the said spring being
interposed between the inside of the cylinder's lower end, and the underside of a
piston or plate attached to the top end of the said upright rod or spindle. The
said cylinder or its equivalent is attached at its top end to the lower end of a
pivotted rod or spindle which is pivotted at its top end to a suitable bracket
secured to the underside of the frame or body of the vehicle. To one or more of
the holes in the arm of the said slipper or shoe I connect by suitable means the
one end of a chain, rope or cord, which is provided with an ordinary slip hook or
its equivalent, and which after passing up and around a pulley or grooved wheel
mounted underneath the vehicle is attached by means of a ring or its equivalent
to a pivotted hook mounted underneath the vehicle in such a manner that it may
be operated or disengaged from the ring by means of an auxiliary chain, rope,
or cord which passes up to the front of the vehicle and is provided with a ring or
its equivalent.
Or as a modification of the two small rods or stays which are attached to the
studs or pins on side of slipper or shoe, I may form them as one flat triangular
piece having an upward projecting part which engages in a suitably shaped pocket
provided at the lower end of the upright spindle or rod, in which modification the
pirotted or other side acting and locking joint may be dispensed with. And in
lieu of forming the said joint on the lower rod or spindle I may form it on the
upper rod or spindle if desired.
The whole arrangement being such that when not in use the slipper or shoe
hangs up in front of the wheel or wheels to be braked in such a position that on
ring on end of auxiliary cord being disengaged from its hook the slipper or shoe
instantly drops down into position in front of the wheel, which then enters on
same, and when desired to take off the brake the slip hook on main chain of brake
is lousened, and so allows the slipper or shoe to run clear behind the wheel, from
which position it is lifted back to its normal position by the party in charge, through.

brake or skid which can be applied and taken off without stopping the vehicle.

Improvements in Brakes or Skids for Lorries, Wagons, Carts, and
other Vehicles.
I, PETER DAWSON, of 99 Maxwell Street, Glasgow, in the County of Lanark,
North Britain, Distiller, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement:-
This invention which relates to improvements in brakes or skids for lorries,
wagons, carts and other vehicles has for its object to provide means whereby the
brake may be applied or taken off without stopping the vehicle, and at the same
time when off the brake is always in a position as to enable it to be instantly
applied.
;
In carrying out my said invention as illustrated in elevation Figure 1, part
elevation Figure 2 and part back view, Figure 3 of the annexed drawings, I form
the slipper
or shoe A, with its arm a on the outside in lieu of the inside as hitherto,
the said arm a being provided with one or more holes, for the necessary chains,
links etc.; the said slipper or shoe A is slightly curved in shape, and provided
with corrugations a' at its front end so as to enable the wheel to enter on the shoe
at once without the shoe slipping the said shoc A, is also provided on its front
side with two or more pins or studs a² to which are attached the lower ends of two.
or more small rods or stays B, which are attached at their top ends to a pivot or
pin b, carried by the lower end of an upright rod or spindle C, which is so formed
as to be capable of passing clear of the cap or hub of the wheel, and the said rod C
is provided with a pivotted or other side acting and if desired locking joint D, the
top end of this rod C passes up through a hole or opening formed in the lower end
of a hollow cylinder E or its equivalent within which is mounted a round, oval or
other spiral or other spring F; the said spring F being interposed between the
inside of the cylinders lower end and the underside of a piston or plate c, attached
to the upper end of the spindle or rod C. The said cylinder E is attached at its
upper end to the lower end of another rod G which is pivotted at its upper end to
a suitable bracket g secured to the underside of the frame or body of the
vehicle, which in the drawings is shown as a lorry.
To one or more of the holes in the arm a of the shoe A. I connect by means of
the ring or otherwise the one end of a chain, rope or cord H which is provided
with an ordinary slip hook arrangement and attached at its other end to a fixed
hook or eye 2 secured to underside of the frame of the vehicle. The shoe may be
suspended (as shown in Figure 2) by means of the ring or by an auxiliary ring J,
or by a suitably shaped eye formed on the arm a, of the shoe A from a pivoted
hook K, mounted underneath the frame of the vehicle in such a manner that the
hook K may be disengaged from the ring or J, or eye on arm at any moment.
and so cause the shoe A to drop down into position in front of the wheel, and so
brake the wheel (as shown in Figures 1 and 3) by means of an auxiliary chain,
rope or cord L, which after passing over or partly around a pulley or grooved
wheel mounted underneath the vehicle, extends along to the front end of the vehicle
where it is provided with an engaging hook and ring or their equivalents so.as
to enable the person in charge to operate the brake without losing control of the
horse or horses.

page_text: As a modification of the two small rods or stays B, I may form them as one flat
triangular piece having an upward projecting piece which engages in a suitably
shaped pocket or its equivalent provided at the lower end of the upright or rod C,
in this modification the side-acting joint may be dispensed with. Or in lieu of
forming the said side-acting joint on the lower rod or spindle I may form it on the
upper rod or spindle if desired.
The whole arrangement is such that when not in use, as shown in Figure 2, the
slipper or shoe A, hangs up in front of the wheel or wheels to be braked in such a
position, that on the ring on end of auxiliary chain, rope or cord L being
disengaged from the hook the shoe instantly drops off the hook K and so falls
into position in front of the wheel, which then enters on same as shown in Figures 1
and 3, owing to the spring F which is now compressed keeping the shoc A hard
against the rim of the wheel. When desired to take the brake off the wheel, the
slip book of the chain H is loosened and the shoe A allowed to run clear behind
the wheel, from which position it is lifted back to its normal position as in Figure 2,
by the person in charge, through the medium of the side-acting joint or pocket
arrangements. Thus providing a brake or skid which can be applied and taken off
without stopping the vehicle.
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
1st. In brakes or skids for lorries, wagons, carts and other vehicles, mounting
the slipper or shoe on the end of a pivotted arm provided with a spring and a
side-acting joint or joints or pocket arrangement, or the mechanical equivalents
of said arrangements, substantially as, and for the purposes hereinbefore described
and shown in the drawings.
2nd. In brakes or skids for lorries, wagons, carts and other vehicles, providing
the slipper or shoe A with a suspending ring J, or eye formed in the arm of
the shoe by means of which the shoe is hung on a pivotted hook when not
in use, substantially as hereinbefore described and shown in the drawings.
3rd. In brakes or skids for lorries, wagons, carts and other vehicles, providing
a pivotted hook K and combining therewith the disengaging gear for same, or
the mechanical equivalent of said arrangement, substantially as and for the
purposes herein before described and shown in the drawings.
4th. The general arrangement, construction and combination of the various
parts constituting my improvements in brakes or skids for lorries, wagons, carts
and other vehicles, substantially as, and for the purposes hereinbefore described
and shown in the accompanying drawings.
Dated this 29th day of February 1892.
