Improvements in Brakes or Skids for Lorries, Wagons, Carts, and
other Vehicles.
We, JOHN STIRLING DOWELL of 455 Saint Vincent Street, Glasgow, in the
County of Lanark, Merchant, and Commission Agent, and PETER DAWSON, of
88 Great Clyde Street, Glasgow, aforesaid, Distiller, 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 :-
This invention relates to brakes or skids for lorries, wagons, carts and other
vehicles and as seen in side elevation in different positions by Figures 1, 2 and 3 of
the accompanying drawings, the improved brake consists of a strut or bracket a
which at its upper end is bolted or otherwise connected to the underside of the
body of the vehicle. The strut or bracket is placed in an inclined position and
it is stayed by a bar c bolted or otherwise connected to it and also to the underside
of the body or frame b of the vehicle. At its lower end the strut or bracket a has
a sleeve a¹ formed on or connected to it through which there passes a rod d preferably
of rectangular section the said rod in its bearings in the sleeve being carried upon
or passing between rollers e for the purpose of reducing or minimising friction. To
the upper end of the rod which has an eye f preferably jointed to it there is con-
nected the rear extremity of a rope, chain or wire g the said rope, chain or wire
from the point of connection being carried over a pulley journalled in a bracket
bolted to or otherwise connected to the underside of the body or frame b of the vehicle
and from the said pulley or roller the rope, chain or wire passes through an eye i
beyond which it has a loop k formed on or connected to it. In conjunction with the
said loop there is provided at the front end of the body a hook or catch over
which when the brake apparatus is out of operation as at Figure 3 of the drawings
the loop k is passed. To the lower end of the rod d there is jointed a brake shoe
or skid m which has a flange or flanges m' made on one or both sides of it to embrace
one or both sides of one of the hind wheels n. At its rearward end the said brake
shoe or skid has its base curved or arched upwards and corrugated or roughened on
the under side.
The joint between the shoe m and the rod d is preferably so made that in its
inoperative position the shoe has a bias towards the wheel and this is or may be
effected by forming a knuckle or projection on the rod as at s Figure 2.
In applying the brake or skid the loop k is lifted off or removed from the hook
whereupon the brake or skid falls into the position illustrated by Figure 2 of the
drawings in which position the upwardly curved rearward end of the skid rests
upon the roadway and the further forward traction of the vehicle causes the wheel n
to override or run into the skid as at Figure 1 and the said wheel is thereby braked
or prevented from turning. In withdrawing the brake the vehicle is backed until
the wheel n is free of or behind the skid which is then pulled up into the position
Figure 3 by the driver again placing the loop of the rope chain or wire over the
hook l.
In lieu of the loop k and hook the forward end of the rope chain or wire may
be connected to an arm of a crank in conjunction with which a toothed rack is
provided for the purpose of holding the skid m in its inoperative or operative
position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The general arrangement and combination of parts constituting the brake or
skid for lorries, wagons, carts and other vehicles, substantially as described with
reference to the excams

page_text: 2. In a brake or skid for lorries, wagons, carts and other vehicles the combination
of an inclined strut or bracket secured to the body or frame of the vehicle a sleeve
on the lower end of such bracket having or not antifriction rollers in the passage
through it, a rod passing through said sleeve and having connected to its lower end
a skid or shoe its upper end being attached to a raising or lowering rope, chain or
wire and which has attachments for enabling the skid or shoe to be held out of
active position substantially as described.
Dated the Thirtieth day of December 1890.
