PROVISIONAL SPECIFICATION.
Improvements appertaining to Rim and Mortice Locks and Latches
of every description in which Followers are employed.
We THOMAS BENTON of Victoria Street, and JOHN WORMINGTON BENTON
of Regent Street, both of Little London, Willenhall, in the County of Stafford,
Manufacturers of Locks do hereby declare the nature of this invention to be as
follows:-
Our invention has for its object to prevent the follower of a lock and latch
being forced beyond its limit of travel, thus rendering the lock more safe, further,
and as an incidental, the objectionable slip of a lock or latch which occurs when
the horns or noses of the follower wear down, will also be avoided by our
invention.
According to our invention we so arrange locks and latches which have followers
that the horns or noses, or their mechanical equivalent, come up against strong
abutments when the follower has completed its normal travel, or the horns or noses
may travel in guides.
In carrying out our invention, for instance, in place of the ordinary horns we
provide the follower with two little plates or arms, and at the ends of these, and
on either side, are fitted or formed little pius, making four in all. In both front
and back plates of the lock or latch we provide slots, of a length commensurate
with the travel of the follower, in which these pins can traverse.
It will be seen that the flat plates or arms take the place of the horns for
shooting the bolt, whilst owing to the pins coming up against the ends of the slots
in the plates it becomes practically impossible to force the follower further.

COMPLETE SPECIFICATION.
Improvements appertaining to Rim and Mortice Locks and Latches
of every description in which Followers are employed.
We, THOMAS BENTON of Victoria Street, and JOHN WORMINGTON BENTON
of Regent Street, both of Little London, Willenhall, in the County of Stafford,
Manufacturers of Locks, do hereby declare the nature of this invention and in what
imanner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
Our invention, has for its object to prevent the follower of a lock, and latch
being forced beyond its limit of travel, thus rendering the lock more safe, further,
and as an incidental, the objectionable slip of a lock or latch which occurs when
the horns or noses of the follower wear down, will also be avoided by our
invention.
According to our invention we so arrange locks, and latches which have
followers, that the horns or noses, or their mechanical equivalent, come up against
strong abutments when the follower has completed its normal travel, or the horns
or noses may travel in guides; and in order that our invention may be fully
understood we have annexed hereto, and herein refer to the same, a sheet of
drawings showing an ordinary ship's lock made according to our invention.

page_text: Fig. 1 is a face view of the lock provided with slots, as hereinafter explained,
and Fig. 2 is a similar view, but with the upper part of the cover plate broken
away in order that our follower may be fully seen. Fig. 3 shows the follower by
itself.

In carrying out our invention, for instance, in place of the ordinary horns we
provide the follower A with two little plates or arms B B₁, and at the ends of
these, and on either side, are fitted or formed little pins, making four in all. In
some instances it will be found quite sufficient to provide these little plates or
arms B B on their one side only with little pins, so that there would then be two
pins instead of four. In the ship's lock shown on the drawings there are only two
little pins as this number will be quite sufficient for such a kind of lock. C. C¹ are
the two little pins.
In both front, and back plates of the lock or latch we provide slots of a length
commensurate with the travel of the follower, in which these pins can traverse, but
it will be understood that when the little plates or arms B B are provided on the
one side only with little pins (C C¹) then it will only be necessary to provide the
one. plate only of the lock or latch with slots, in the drawing it is the cover plate D
which is shown provided with the slots E E' in which the little pins C C¹ can
traverse.
It will be seen that the flat plates or arms B B' take the place of the horns for
shooting the bolt F, whilst owing to the pins coming up against the ends of the
slots in the plate it becomes practically impossible to force the follower further.
Having now particularly described, and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements appertaining to locks and latches, of the kind specified,
consisting in making them so that the horns or noses, or their mechanical equivalent,
of the follower, will, at the end of its normal travel; come up against strong
abutments, substantially as, and for the purposes herein before described.
2. In locks, and latches of the kind specified, (a), providing the follower with 3
plates or arms B B' having little pins, (b), providing the front, and back plates, or
one of them only, with slots, all substantially as, and for the purposes herein
before described.
3. The general arrangement, and construction of lock substantially as herein
before described, and shown on the accompanying sheet of drawings.
