No. XIX.
A little engine, within a coach, whereby a child may stop it, and secure all persons within it, and the coachman himself, though the horses be never so unruly, in full career; a child being sufficiently capable to unloose them, in what posture soever they should have put themselves, turning never so short; for a child can do it in the twinkling of an eye.
NOTE.
There are but few persons who will disallow the utility of an invention, whose object is to prevent, as much as possible, the frequent and terrible accidents which occur from the present mode of attaching horses to carriages, and other vehicles; that these might in a great measure be avoided, by the application of the Marquis's invention, and a legislative enactment to secure its adoption, there can be no doubt.
To accomplish this very desirable object, a bar, of equal length with the axle-tree, to which is fixed the pole and traces; must be furnished with three iron bolts made to fit a like number of sockets in the axle-tree; and from which, the additional bar may be readily raised, by the application of a common lever: either by the pressure of the driver's foot, or by a string made to communicate with the body of the vehicle. For a chaise the apparatus will be no less simple, with the exception of a small resting bar, or foot, which it will be necessary to discharge by the same lever which sets at liberty the horse, and by this means prevent the sudden jerk, that must otherwise occur in a two wheeled carriage.
