LOCKS or Carriage
I, HUGHES REID DAVIES, M.R.C.S. Eng., and L.R.C.P., London, of
82, Bow Road, London, E. do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in locks for carriage and other doors,
and consists in providing a triangular or approximately shaped piece of metal
(constituting the bolt) which works upon a pivot, a dependent, weighted handle
or handles being connected to the said triangular bolt preferably at, or near the
angle formed by the greater sides, such handle or handles being so connected as to
have a partial hinge-like movement independent of the said bolt.
The action of depressing the handle causes one of the angles of the triangular
bolt aforesaid to enter a recess in the striking plate, and to securely lock the door,
while the reverse action of the handle withdraws the said locking angle of the bolt
and so unlocks the door.
The mechanism may be enclosed in any suitable case, in which, or in the sides of
the door, the handles (which constitute levers) are fulcrummed.

Improvements in Locks for Carriage and other Doors.
I, HUGHES REID DAVIES, M.R.C.S. Eng., and L.R.C.P., London, of
82, Bow Road, London, E. 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 improvements in locks for carriage and other doors,
and consists in providing a triangular (or approximately so) shaped piece of metal
working upon a pivot, which constitutes the bolt, and a dependent handle or
handles suitably weighted, and fulcrummed in the sides of the door and bolt
casing and connected to the bolt in such manner that by raising or depressing
same the door may be locked or unlocked as may be required, that is to say, the
action of depressing the handles (which sink by their own weight) causes one of
the angles of the triangular bolt to enter a recess in the striking plate and so
lock the door, while the reverse or lifting action of the handles withdraws the
lecking angle of the bolt from the striking plate and so unlocks the door.
And in order that this my invention may be fully understood and readily
carried into effect, I will now describe same with reference to the accompanying
ID

page_text: sheet of drawings and the letters and figures of reference marked thereon, that is
to say:
Fig. 1 is a side elevational view of the bolt in its locked position, and
Fig. 2 is a similar view of the bolt in the unlocked position.
Fig. 3 is a face view of the striking plate.
a is the triangular shaped bolt pivotted at 6 to the sides of the lock casing;
e is a bar passing through the bolt and through the sides of the lock casing. By
reason of the angle formed by the junction of the greater sides of the triangular
bolt weighing more than the striking angle, and also by reason of the additional
weight of the bar handles, the handles form a dependent, weighted lever, which,
by its weight alone, locks the door.
As the handle is depressed, (as shewn particularly in Fig. 1) the angle a¹ of the
bolt projects beyond the lock casing or door d and enters the recess e' in the
striking plate e, (Fig. 3) being the angle which strikes the projecting bolt.
It will be obvious that two handles e may be attached to the bolt if required,
one upon each side of the door. As shewn in Fig. 2, the handle c upon being
raised withdraws the angle a' of the bolt a from the recess in the striking plate
and permits of the door being opened.
Figs. 4 and 5 are diagram views of the outside of the lock shewing, in Fig. 4,
how the handle c may be locked in position by the bolt g, and in Fig. 5, how same
is released.
It will be also obvious, that to allow movement of bar c, a slot must be cut in
lock casing or door d.
To avoid, as inconvenient in some instances, the cutting of the lock casing and
wood work of the door, I apply the handle or handles directly to pivot b, in such a
manner that the handle or handles act directly upon the metal bolt a; that is to
say: When the handle is raised the locking angle of the bolt is withdrawn from
the recess e¹ in the striking plate e, and the reverse action takes place when the
handle is released, and drops by its own weight as before described.
Locks constructed as herein described and shewn will be found advantageous
and convenient for use upon private carriages, cabs, and other vehicles, and upon
all doors where a secure fastening of easy manipulation is required.
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 :-
1. The improvements in locks for carriage and other doors, substantially as
hereinbefore described and shewn.
2. In locks for carriage and other doors, the triangular (or approximately so,)
shaped metal bolt pivoted to the sides of the lock, sinking into a locked position
by its own weight, in combination with the weighted, dependent actuating handle
or handles through the side or sides of the lock or door; all constructed, arranged,
and operating substantially as hereiubefore described and shewn.
