IMPROVEMENTS IN RIM LOCKS DRAWBACK LOCKS & LATCHES
Year: 1885

page_text: I, JAMES HILL of 100° Queen Victoria Street in the City of London, Lock
Merchant and wholesale Ironmonger do hereby declare the nature of my said
invention for IMPROVEMENTS IN RIM LOCKS DRAWBACK LOCKS & LATCHES to be
as follows:
I claim originality in construction of Rim Locks with (ornamental) flanges to
suit the prevalent styles of Architecture so that flange Rim Locks will suit doors
either left handed or right handed, and whether the doors open inwards or
outwards.
This invention applies to all kinds of flange Locks and Latches, viz:-Follower
Locks, and Drawback Locks, Night Latches Rim Latches, and Dead Locks.
The method by which I make these Locks reversible is that the locking bolt and
Latch-bolt are exactly same size and equi-distant, and the Latch-bolt made to
revolve.
The flanged case is made with fore-end, which latter has two holes of equal size
and equi-distant to receive the aforesaid bolts.
The Lock is made separate and is held in frame by a set-screw. Upon releasing
the set-screw the Lock will lift out and the Latch bolt can be turned round and
then re-inserted into the locking-bolt hole, or "vice-versa" to suit doors hung on
either right or left hand, opening either inwards or outwards.
Dated this 31st day of December 1884.

Agent for James Hill.

page_text: Improvements in Rim Locks, Drawback Locks, and Latches.
I, JAMES HILL of 100ª Queen Victoria Street, in the City of London, Lock
Merchant & wholesale Ironmonger do hereby declare the nature of my invention
for IMPROVEMENTS IN RIM LOCKS, DRAWBACK LOCKS & LATCHES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
By this invention Rim Locks & Latches, with flanges of any design, can. be
instantly converted into right or left hand, also to what is known in the trade as
Reverse Bolt" Locks for doors opening outward.
"$
The moulded case with flange.(Fig. 1.) is made in one piece with 2 holes in face
or fore-end (fig. 5) of equal size, and equi-distant to receive the bolts of Lock.
The Lock itself (Fig. 3.) fits into said case, one side resting against rebate (fig. 2)
and the other side flush with back of frame or case. It is then kept rigid by set
screw (8) at back of case.
The frame having both bolt-holes of equal size, and the Lock having bolts of
equal size to correspond and all equi-distant, the Latch-bolt can be inserted into
locking-bolt hole or "vice-versa" as may be required. The Latch or spring-bolt of
Lock will turn round when not in case, (by making "nose" of bolt separate, with
loose rivet,) but upon being passed through either hole when it is decided what
"band" the Lock is required, it cannot be turned round.
Fig. 4. on drawing represents frame & Lock put together for use, while fig. 6,
gives back view of same. By taking the Lock out of the case and turning the
Latch-bolt round it can be made instantly into Right or Left hand.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
"
1. Originality in making flange Rim reversible from Right to Left hand and
vice-versa."
2. The method by which the Locks are made to reverse, i.e. both bolts of equal,
size and equi-distant for interchanging into corresponding openings in fore-end or
face plate.
3. The applicability of this principle for making other kinds of Locks reversible,
viz: by having both bolts of equal size, and holes in face plate to correspond, so
that Latch-bolt will fit into Locking-bolt hole and vice-versa."
