page_text: I, GEORGE NOCK, of 303A, Bradford Street, Birmingham, County of Warwick,
Brass Founder, do hereby declare the nature of this invention to be as follows:-
This invention relates as hereinafter described to an improved combined door
latch and bolt and has for its object to provide means whereby a sliding bolt may
be combined with an ordinary door latch thus saving the expense of both articles
attached to the door and forming an extra security for the latch by preventing
it from being raised on the outside.
In carrying my invention into effect I provide an ordinary latch pivoted to
a door plate in the ordinary way. To a convenient part on the face of the latch
I attach a sliding bolt by fixing or forming a loop and eye and fit therein a
sliding bolt which is held in position by a suitable knob the shank being screwed
passes through a slot formed in the latch the screwed part being provided with
a nut on the underside of the latch thus the bolt is capable of sliding backwards
and forwards longitudinally in the said loop or eye and can be retained in either
the shot or withdrawn position by simply turning the screw knob which draws
the nut tightly upon the reverse side of the latch. I provide the guide or staple
plate with a loop or cavity to receive the end of the bolt when shot. It will be
apparent that the latch may be used as an ordinary latch, and when engaged in
its closed position with its end engaging in the catch on the jamb the sliding
bolt may be shot into the staple plate thus effectively securing the door and pre-
venting the latch from being raised on the outside.
I may in some cases attach the sliding bolt near the end of the latch and cut a
slot or cavity in the catch attached to the door jamb to enable the end of the
bolt engaging therein when shot.

An improved Combined Door Latch and Bolt.
I, GEORGE NOCK, of 303A, Bradford Street, Birmingham, in the County of
Warwick, Brass Founder, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates as hereinafter described to an improved combined door

page_text: latch and bolt and has for its object to provide means whereby a sliding bolt may
be combined with an ordinary door latch thus saving the expense of having both
articles attached to the door and forming an extra security for the latch by pre-
venting it from being raised on the outside.
In carrying my invention into effect I provide an ordinary latch pivoted to
a door plate in the ordinary way.
To a convenient part on the face of the latch I attach a loop or eye and fit
therein a sliding bolt which is held in position by a suitable knob the shank being
screwed passes through a slot formed in the latch the screwed part being provided
with a nut on the underside of the latch. Thus the bolt is capable of sliding
backward, and forward longitudinally in the said loop or eye and can be retained
in either the shot or with drawn position by simply turning the screw knob
which draws the nut tightly upon the reverse side of the latch.
I provide the staple plate with a loop or cavity to receive the end of the bolt
when shot.
The latch may be used as an ordinary latch and when engaging in its closed
position with its end engaging in the catch on the jamb the sliding bolt may be
shot into the staple plate thus effectively securing the door and preventing the
latch from being raised on the outside. I may in some cases attach the sliding
bolt near the end of the latch and cut a slot or cavity in the catch attached to
the door jamb to enable the end of the bolt engaging therein when shot.
The nature of my invention will be more clearly understood from the accom-
panying drawings the same letters of reference indicating similar part throughout.
Figures 1, 2 and 3 illustrate respectively a front and end elevation and plan
of my improved combined door latch and bolt, Figures 4, 5 and 6 are similar
views showing a modification of the same.
A represents a door latch pivoted at B to a door plate D. C is a sliding bolt
working in the loop E and capable of sliding into the loop I of the staple plate K
as shown in dotted lines. When shot the latch cannot be raised from the out-
side. The knob F having a screwed shank G which is furnished with the screw
nut His arranged to retain the bolt C in its shot position by a turn of the knob F
which forces the bolt against the face of the latch; the latch is prevented from
being raised from the outside by shooting the bolt C. The effect of screwing up
the knob F is to retain the bolt C in its closed position with its end engaging
in the catch L on the door jamb. The catch L to take the latch A is of ordinary
construction.
In the modification shown at Figures 3, 4, and 5 the sliding bolt C is attached
near the end of the latch A and arranged to engage in the cavity or cutaway
part M of the catch L which is attached to the door jamb the action being the
same as in Figures 1, 2, and 3.
Having now particularly described and ascertained the nature of my said in-
vention. and in what manner the same is to be performed I declare that what I
claim is:
The combination of a door latch and sliding bolt consisting of the latch A the
sliding bolt C, loop E and staple I, or notch M, operating substantially as
described and illustrated and for the purpose set forth.
