A New Expanding LOOK.
MATTHEW HENRY NEWTON 100 Great Dover Street Borough S.E. London,
Bookbinder do hereby 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 :-
The object of this invention is to construct locks for books writing cases and
other similar purposes in which the distance between the lids of the book or case
may be varied and yet allow the same to be locked.
Locks constructed according to this invention are particularly applicable to
ledgers albums scrap books and the like which are liable to become thicker from
constant use or by reason of scraps photographs or other articles being inserted
therein.
Now according to this invention 1 attach the lock and the hasp to the lids of
the books by the usual plates.
I secure the lock or the hasp to tubes rods or wires at each side thereof which
tubes rods or wires slide in or on tubes attached to a piece of metal hinged to the
lid plates.
To the said piece of metal I attach also a male or female screw engaging with a
female or male screw secured to the hasp or lock the female screw in either case
being capable of rotation to compensate for the varying distance between the lids
of the book when closed.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in
which
Fig. 1 represents front view of a lock constructed according to this invention.
Fig. 2 is front view partly in section of the same lock attached to a book.
Fig. 3 is side view of the lock.
The same letters denote the same parts in all the figures.
a is the hasp plate 6 the lock plate which plates are attached to the lids a¹
and 6 respectively. To the plate 6 is hinged at xx a piece of metal c having wires
or tubes dd secured thereto in or on which slide rods tubes or wires ff attached to
the lock g h is a screw attached to the lock 9 j is a sleeve or nut revolving on a
stud secured to the plate c which sleeve is provided with an internal screw

page_text: engaging with the screw h so that by rotating the sleevej in one direction or the
other the lock g is caused to approach or recede from the plate b.
Although I have described the lock as having the lock g adjustable it is evident
that the catches or hasps k k may be mounted on the sliding rods and the lock be
stationary without departing from the spirit of the invention.
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. In locks for books and the like the combination of a piece of metal such as c
having attached thereto tubes or wires such as d and a rotating sleeve or nut such
as with a lock 9 having attached thereto wires rods or tubes such as ff sliding in
or on the tubes d d and a screw engaging with the sleevej and a means for
attaching the whole to the lid of a book or the like all substantially as hereinbefore
specified and for the purpose stated.
2. In locks for books and the like the combination of a piece of metal such as c
having attached thereto tubes or wires such as d and a rotating sleeve or nut such
as with a hasp or hasps having attached thereto rods or tubes such as ff and a
screw engaging with the sleeve and a means for attaching the whole to the lid
of a book substantially as hereinbefore specified and for the purpose stated.
3. Locks for books and the like constructed as herein before described and shewn
by the accompanying drawings and operating in the manner specified.
Dated this 1st day of August 1894.
