of Carriages from the Outside.

I, ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, 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, reference being had to the accompanying
drawings, and to the letters and figures marked thereon, as communicated to me,
that is to say :-
This Invention has for its object improved means for effecting the automatic
opening of the doors of carriages, by pushing the bolt, this pushing taking place
from the outside, and being effected either by a piece or pusher mounted on a rod or
spindle which can be worked from the outside by pushing a button or knob projecting
on the front of the vehicle, or by a push-piece mounted at the end of a jointed lever
which may be operated by the coachman pressing upon a knob or button.
The invention may be carried into effect in different ways, and I proceed to indicate
a very simple one in the accompanying drawings.
C, is a lever, having its fulcrum at B, and arranged in a hollow cut in the door
post of the carriage. This lever is free to turn about its axis d, by means of the rod
or spindle a, terminated by the ring or button A, which is pulled by the coachman.
By reason of the difference of the arms of the lever, a slight pull exerted on this
button will be sufficient to strongly push, against the bolt X, the piece E, or pusher,.
which terminates the short arm of the lever C, (fig. 1.). In order to reduce friction
this piece is faced with brass, or other suitable metal. When the coachman lets go
the button A, a spiral spring R, restores the lever to its initial position against the
plate B. This plate is fixed to the door-post of the carriage and carries the
bearings D, D', between which the lever works. In this position, (fig. 2) the push
piece E has returned to the hollow in the door-post M, and the bolt entering the
staple, as usual, the lock becomes fastened.

page_text: Fig. 3, shews the whole apparatus in front view. Fig. 4 shews, in plan, the end of
the bolt, cut on the bevil, a, b; the push-piece E likewise terminates in a corre-
sponding bevil, which, when the push-piece acts on the bolt, commences to cause the
door to open. Further, when the bolt has quitted the staple, a spring, or other
suitable means, brings about the automatic opening of the door.
This system allowing of doors being opened from the outside, or to be opened by
the coachman, by means of any gear, without getting down from his seat, the use of
handles projecting on the outside, is dispensed with, thus obviating soiling of the
hands, when such handles have been dirtied by the wheels throwing up mud on them.
Having now described the nature of the invention and in what manner the
same may carried into effect I declare that I claim, as communicated to me by
my foreign correspondent:
The combination with the locks of carriages, of a piece designed to push the bolt
either by means of a rod or spindle, furnished with a button or ring, on which such
piece is fixed, or by means of a lever gear, or other gear, permitting the coachman to
push the bolt, without getting down from his seat, by pulling, or by bearing upon a
button, or ring, the door of the vehicle opening automatically by a spring, or otherwise,
as soon as the bolt has been released, substantially as herein described.
