PROVISIONAL SPECIFICATION.
A Combined Latch and Bolt for Doors, Windows, and the like.
I, JOHN BOSHER SEWARD, of Crown Works, Wokingham Berks, Builder do
hereby declare the nature of this invention to be as follows:-
My invention relates to a combined latch and bolt.
Reference is to be had to the accompanying drawing forming part of this
specification in which Figure 1 is a sectional elevation of the latch and bolt, when the
door is opened, Figure 2 when the door is shut and Figure 3 is a horizontal section
through the door and frame.
The bolt A has an extended arm B pivoted near the bottom at F, part of this
extended arm below the pivot at C is acted upon, when the door or window is quite
closed, by an ordinary spring latch G fixe in the jamb or frame of the door or
window, and which will throw the bolt A into the frame or jamb of the door or
window.
The door or window is opened by turning, by means of ordinary door spindles H
the lever E which acting on the extended arm C throws the bolt back again into
the case.
D is a sliding locking bolt for holding the bolt A in a locked position
when operated by a key.
