COMPLETE SPECIFICATION
An Improved Appliance for Locking Doors,
I, SAMUEL MARTIN GULLY, of Rumwell Hall, Taunton, in the county of Somerset,
late Major, Royal Sussex Regiment, do hereby declare the nature of this invention
and in what manner the sanie is to be performed, to be particularly described and
ascertained in and by the following statement
This invention consists in an improved appliance for locking doors.
In convenient proximity to the door handle is pivotted on the door a plate which
may conveniently be termed a hasp In the underside of the hasp is a notch or
recess.
The hasp is so placed in relation to the handle of the door that when it, the hasp,
is turned on its pivot to a horizontal position over the bandle the neck of the knob of
The slot
the handle 18 received in the notch and the handle cannot then be turned
through which the pivot pin of the plate is passed is elongated to allow the hasp the
necessary amount of play to enable the notch to descend fully on the neck of the
knob.
A swinging stop may be placed in front of the handle and so arranged that as
the hasp is turned down to lock the handle the stop is moved aside by the hasp,
and, when the latter has passed clear, the stop returns to its normal position over the
hasp and prevents it from rising off the neck of the knob of the handle.
To release the handle the swing stop is moved aside and the hasp is turned back on
its pivot.
Referring to the accompanying sheet of drawings, Fig. 1 thereon represents an
elevation and Fig. 2 a plan of the improved appliance for locking doors in which
this invention consists.
Pivotted to the face of the door a 19 a plate b, which may conveniently be
termed a hasp, in the underside of which is a notch or recess.
The hasp is so placed in relation to the handle c fixed on the spin lle whereby
the latch of the door is operated that when the hasp is brought to the locking
position, as shown in the drawing, the neck e of the knob or handle is received
into the notch or recess of the hasp.
The slots, through which the pivot pin d of the hasp b is passed, is elongated
to allow the play requisite to enable the hasp to descend fully over the neck e of the
knob or handle c.
The neck e of the knob is flat at both sides and on the top As will be readily
understood, when the hasp 6 is turned over on the handle, atter closing the door, the
handle cannot be turned. Consequently, the door is thereby locked.
In front of the handle is a stop f free to swing on the pin g by which it is secured
to the door. When, in bringing the hasp to the locking position, the front end thereof
comes into contact with the stop f, the latter swings on its pivot and after the hasp
has passed below it the stop swings back above the hasp and prevents it from rising,
under the influence of a jerk, off its seat on the neck e of the handle
To release the handle the hasp is turned back on its pivot, as indicated in dotted lines
at Fig. 1.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. An improved door-locking appliance consisting of a recessed or notched hasp
such as b nivotted through the elongated slots to the face of the door and so placed

page_text: position the squared or flat-sided neck of the knob or handle fixed to the spindle
whereby the latch is operated, is received into the notch or recess of the hasp,
substantially as herein before described and shown in the accompanying drawings.
2 The combination with the notched hasp and the square-necked knob c, of
the swinging stop ƒ for preventing the hasp from being jerked off its seat on the
knob as, herenbefore described.
