page_text: We HENRY FRANCIS of Cambridge Villa Castle Road, Newport, Isle of Wight
Gentleman, and ALFRED EDWARD CAREY of 170 North Street Brighton, Civil
Engineer do hereby declare the nature of this invention to be as follows:-
The object is to provide for doors a simple fastening to be opererated as an ordinary
lift latch from both sides of the door and as a sliding holt from one side of the door
only.
The invention consists essentially in making a lift latch with a slot at one end
through which a pin or pivot secured to a carrying plate passes, and in combining
therewith a hasp and box for engaging with the free end of the latch.
The latch plate is secured to the door in any convenient manner, and is provided
with the necessary knobs, handles, spindles, and lifting piece for giving motion to
the latch. The hasp and the box are secured to the door jamb in the required
position.
The action is as follows:-When the latch has the pin or pivot at one end of the
slot, the said latch engages with the hasp alone and may be raised by means of the
knobs or handles from both sides of the door. When the pin or pivot is at the other
end of the slot the free end of the latch has been slid into the box and can only be
drawn back from one side.
Under a modification the slot is made in the carrying plate and the pin or pivot is
secured to the latch.
A further improvement consists in making the slot with a recess at one or both ends
to receive the pin or pivot and prevent accidental displacement of the latch.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan, Figure 2 a face view and Figure 3 an end view of our improved
combined latch and bolt, Figure 4 is an end view of the hasp and, box.
a door, blatch
provided with a slot c through which passes the pin d secured to the carrying plate e,
knob secured to the latch, g knob provided with a spindle h which passes through
the door a and is fitted with a cam piece i for raising the latch, door jamb, k hasp
and box fixed to the plate m. The plate m is secured to the door jamb by screws or
as may be otherwise found convenient. The slot e may advantageously be made with
recesses at one or both ends to prevent accidental displacement of the latch.
The action is as follows:When the latch is in the position shown as regards the
slot c and pin d the said latch engages with the hasp & alone and may be raised free
therefrom by turning either of the knobs f, g. When the latch is slid forward in the
direction of the arrow by means of the knob f, the said latch enters the box / and it
cannot be raised or withdrawn therefrom except by means of the knob f.
Figure 5 is a sectional view showing a modification of apparatus in which the
slot is made in the plate e and the pin d is secured to the latch b.
Figure 6 is a face view of a portion of our improved apparatus showing a
modification of the hasp and box, here a pin or stud is used to prevent the latch
from being raised instead of a box l.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed-we declare that what
we claim is :-
C
The combination of a latch 6 slot c pin d and knobs f g with a hasp k and box / or
equivalent devices, substantially in the manner and for the purpose set forth.
