Improvements in Slam Locks or Latches for Broughams and
other Vehicles.
We FRANKLIN DAVIES of 15 Greenfield Crescent Edgbaston near Birmingham in
the County of Warwick Brassfounder and SAMUEL WILKES of Excelsior Works
44 The Green Bloxwich in the County of Stafford, Lock Manufacturer do hereby
declare the nature of this invention to be as follows:-
Before describing our improvements it will be as well to state that in all locks
or latches used for the above purposes, there is a follower, close up against the
front or fore-end, which is operated by a handle from the outside of the vehicle-that
is to say by virtue of the spindle attached to the handle passing through the square
hole of the follower the latter is turned and withdraws the bolt.
From the fact however of the ordinary followers being only about half-an-inch in
depth from the axis on one side to the axis on the other they have been found to soon
work loose and become shakey, and it is this defect which we aim at remedying.
In constructing a lock according to our invention we employ a follower extended
in depth from the back of the lock-plate, to nearly the front edge of the fore-end of
the said lock-plate-that is from one inch and three fourths to two inches or more as
the case may require, and being covered by a cranked cap or cover-plate in which the
follower works as well as in the lock-plate greater firmness and wear is added to the
same.
We do not however strictly confine ourselves to the exact details herein described
as the same may be open to some slight modifications.

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 :-
In constructing a lock according to our invention we employ a follower extended
in depth from the back of the lock plate to nearly the front edge of the fore-end of
the said lock plate-that is from one inch and three fourths to two inches or more as

follower works as well as in the lock plate, greater firmness and wear is added to
the same.
Inasmuch as our improvements relates only to the follower, in the accompanying
drawings with broken lines, we refer solely to that.
a
Fig. 1 is the follower-bb is the cover plate. Fig. 2 is a side section of Fig. 1.
Fig. 3 is the follower.
It will therefore be seen that the object of our improvements is that of giving
greater stability to the follower and to prevent it becoming loose and shakey with wear,
thus remedying a defect which is so common in all other locks of this description.
Having now particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed, we declare that what we claim is-
The application of a deep follower to locks for Broughams and other vehicles
substantially as herein described and illustrated by the accompanying drawings.
