Improvements in Locks.
We, CHARLES SHAW of No. 21 Waterloo Road South, Wolverhampton, in the
County of Stafford, Architect, and FRANCIS JOSEPH JAMES GIBBONS of
St. John's Works, in the same place, Lock Manufacturer, do hereby declare the
nature of this invention to be as follows
1
Our invention relates to improvements in locks and, inore particularly, to
improvements in the connection between the key and the bolt.
In carrying it into effect we form the keyway through the knob or knobs as tho
case may be The locking device which the hey directly operates, may be of
any suitable type and may be adapted to act directly upon the bolt either by
protrusion, engagement or obsti uction, or to act directly upou either of the kuobs
independently of the other or upon both, by preventing either of them, or them both
directly or through their spindle, from being turned
The invention does not limit us in respect of the position of the knob or of the
knob spindle That may be either central or as near to the door edge as may be
practical or dosned.
The knob on each side may be keyholed to receive its own key, the latter being
adapted to lock the bolt or both knobs o either of them against the action of the
key from the opposite side.
The present invention is applicable to any type of lock having one or more bolts
as well as to night latches and the like

We, CHARLES SHAW of No 21 Waterloo Road South, Wolverhampton, in the
County of Stafford, Architect, and FRANCIS JOSEPH JAMES GIBBONS of
St. John's Works, in the same place, Lock Manufacturer, do bereby 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 :-
Our invention iclates to improvements in locks and latches and is applicable to
any type of lock having one or more bolts as well as to might latches.
The pincipal object of it is to provide a common axis for the key and knobs
and this is accomplished by making the key hole through the knob or knobs The
usual spindle is discarded, the knobs being made fast to the follower which is cut
away of cranked to make room for the cugagement of the key web with the bolt.
The invention does not limit us in respect of the exact nature or construction or
operation of the locking device which the key actually operates. It may be
arranged to act directly upon the bolt by proti usion, engagement or obstruction.
It may, as an alternative, be arranged to act directly upon either of the knobs
independently of the other of them, or upon both knobs, by a device adapted to
lock it or them against being turned.

page_text: The knobs may be placed as near the edge of the door or as far from it as may
he convenient.
The knob on each side of the lock may be keyholed.
Referring to the accompanying diawings:--

C is the bolt
It is shewn as under the control of the key d, gated tumbler e and
stump for locking and unlocking, as heretofore. Its retraction is effected in part
by the key d. such retraction being completed by the engagement of one of the
follower horns, &, with the respective incline on the lever . The latter is
pivotted upon a stud fast to the case and standing up through a slot in the
bolt plate c The nose of the lever has an incline adapted to engage n
corresponding meline on the plate c¹ The dnection of these two inclines is
adjusted to impart the desmed motion to the plate c whenever the nose of the
lever is swung on its pivot by either of the follower hoins 62. is a spring
adapted to return the lever & after it has been swung down by one of the horns b².
The two inclines 3, 63 and the two horns, are so situnted, respectively that an
Incline is always engaged with its horn, and that when the lever is held in its
normal position by the spring, both horns are in contact with their respective
inclines
flaving now particularly described and ascertained the nature of our said inveu-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
