We, CLARENCE ROBERT HECKFORD, of the firm of Joseph Spink and Son, of 155
Lower Stafford Street, Wolverhampton in the County of Stafford, lock manufacturers,
and MARK ROBERT ISAAC STANLEY, locksmith in the employment of the said firm,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object a novel combination of lock and lifting latch
in which a single bolt is made to answer both as the locking and latching bolt.
A combined lock and latch, constructed according to this invention, has a single
bolt which may be shot forwards and backwards by a key in the ordinary or any
convenient manner, and which, when shot back, may be lifted, against the pressure of
a spring, by means of a follower operated from a spindle. The bolt head stands
forward from the fore-end of the case, when in its unlocked position, sufficiently to
latch with a catch or staple, and the lower edge is rounded or bevelled to make it self-
latching as the door to which the combined lock and latch is attached is closed. As
the bolt is raised it turns on a stump, which projects into a slot in the tail of the bolt,
as a fulcrum, and such stump acts also in the ordinary manner as a guide to the bolt
as it is moved endways by the key. In order to allow the bolt to be lifted when in its
unlocked position, a notch is formed in its upper side opposite the upper edge of the
opening through the fore-end of the case, or such opening is formed to give the
necessary clearance above the bolt, but the former method is preferred as preventing
the bolt from being tampered with when locked. The catch or staple is, of course,
formed to receive the end of the bolt as it is shot forwards by the key.

Lower Stafford Street, Wolverhampton in the County of Stafford, lock manufacturers,

statement:
This invention has for its object a novel combination of lock and lifting latch in
which a single bolt is made to answer both as the locking and latching bolt.
A combined lock and latch, constructed according to this invention, has a single
bolt which may be shot forwards and backwards by a key in the ordinary or any
convenient manner, and which, when shot back, may be lifted, against the pressure
of a spring, by means of a follower operated from a spindle. The bolt head stands
forward from the fore-end of the case, when in its unlocked position, sufficiently to
latch with a catch or staple, and the lower edge is rounded or bevelled to make it self-
latching as the door to which the combined lock and latch is attached is closed. As
the bolt is raised it turns on a stump, which projects into a slot in the tail of the bolt,
as a fulcrum, and such stump acts also, in the ordinary manner, as a guide to the bolt
as it is moved end ways by the key. In order to allow the bolt to be lifted when in
its unlocked position, a notch is formed in its upper side, opposite the upper edge of
the opening through the fore-end of the case, or such opening is formed to give the
necessary clearance above the bolt.
of
This invention will be readily understood on reference to the drawings herewith, of
which figure 1 is an elevation of a combined lock and latch, constructed according to
this invention, with the cap-plate removed so as to expose the interior mechanism.
The bolt A is guided upon a stud or stump a, upon which as a fulcrum it is also capable
of being turned by means of a follower through which an ordinary door spindle
passes, such spindle being, of course, provided with knobs or other "handles. The
forward end of the bolt projects sufficiently, as shewn, when the bolt is in its shot
back position, to latch behind a staple, and is bevelled or rounded on its bottom inner
corner, as shown by shade lines, figure 1, and in end elevation by figure 2, to make it
self-latching as the door to which the lock is affixed is closed in. The fore-end
the case is shown in section. A. notch is formed in the top edge of the bolt, as shewn,
to admit of the bolt being raised when shot back, or the hole through which the bolt
passes in the fore-end may be sufficiently deep to allow of the raising of the bolt. The
bolt is raised, whether by the aid of the follower, or in self-latching, against the
pressure of a spring, by which it is rapidly depressed again on the withdrawal of the
force by which it has been raised. When the lock is of the tumbler type, as shewn,
the tumbler (shewn chiefly by broken lines, figure 1) may be conveniently carried on
the stud a, and the stump k of the follower-may-conveniently project into a gating e
formed with downward branches d and e, one at each end. When the bolt is raised

page_text: for latching or unlatching the tambler is, of course, raised therewith, when it is made
to gear with the bolt in the manner shewn, and the tumbler spring tends to aid in the
rapid return of the bolt to its downward position; but it is preferred to use the spring f
also for the purpose of rapidly returning the bolt.
A top edge view of the bolt is shewn by figure 3, in which n and are, flanges upon
which, respectively, bear the follower horns and the spring f.
A suitable staple is shewn in front elevation by figure 5. It is of the box type, and
has an opening through which the head of the bolt passes as it rises over a striker
in latching. When the bolt is shot forwards by the key its forward end is moved
behind the part of the staple.
In lieu of the notch i, the top corner of the bolt head may be cut out, as shewn atm,
figure 4.
Levers, gearing with a stump on the bolt in the usual way, may of course be
substituted for the tumbler.
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
clain is:
1. The novel combination of lock and latch, substantially as described.
2. A combined lock and latch in which the locking bolt may be operated also as a
lifting latch, substantially as described.
3. A locking bolt capable of sliding upon a stud a and of being turned thereon as
on a fulcrum by means of a spindle fitted with handles and operating through a
follower, with means which admit of the rising of the forward end of the bolt when
unlocked, and with means by which the bolt is rapidly returned upon the withdrawal
of pressure by which it has been raised, substantially as described, for the purpose
set forth.
4. In a combined locking and latching bolt, a notch or cut-away part m, substan-
tially as described and shewn, for the purpose set forth.
5. The novel combination of lock and latch substantially as described and shewn by
the drawings herewith, and also the modification thereof as described in which levers
are substituted for the tumbler.
