This invention relates to a puzzle keyless lock, for locking boxes, cases, and
bags.
The accompanying enlarged drawings, will be understood by the following
description of the invention as applied to a tobacco box.

used as an ordinary box with catch, by retaining the bolt (G) in the disc (A).
All that is necessary to lock the box, is to set the combination of numbers and the
bolt (G) drops.
I claim to have invented the various parts as herein described, each part to be
made of metal, and of such suitable size and shape as will suit the strength of any
kind of metal, and which will come within the scope of my invention.

1, EVAN DAVIES, 25, Sherwood Place Llwnypia, Glamorganshire, Engineer,
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 :-
This invention relates to a puzzle keyless lock, for locking boxes, cases, and
bags. The enlarged drawings "left with the Provisional Specification" will be
understood by the following description of the invention, as applied to a tobacco
box.
Figures I. and II. A, represents a small disc, with numbers near the circum-
ference, and on the outside; in the centre of which there is a small hole for
rivet (F) also a hole deep enough to contain a bolt (G). B, a larger disc with
hole in centre for rivet (F), also hole for bolt (G) to pass through; this also is
numbered as shown on the outside. C, lid or cover, with hole in centre for
rivet (F), also hole for bolt (G) to pass through; this also is numbered as shown
on the outside, and the end of the cover has also a bent catch in hook form (CI)
for securing lock. D, slide plate and hinge combined in which a hole is made for
rivet (F) and also a hole for bolt (G), both holes in this part are made into one, to
enable cover (C) to slide as far as rivet (F) will allow, when the bolt is withdrawn,
as shown in Figure I. E, guide plate to work on slide plate (D) and is secured to
lid or cover (C), it also prevents bolt (G) from falling out. F, rivet and washer,
the rivet acts as a common centre, around which the discs (A) and (B) revolve; it
also regulates the distance the slide can be withdrawn. G, bolt in the form of a
small disc, made to fit the bolt holes easily, and of such thickness as to allow
clearance for discs (A) and (B) to turn on rivet (F) freely, when the lock is
secured. CII, hole in side of box for securing the catch (CI) in position.
Figure I, section through centre of box and lock, showing lock open.
Figure II, section through centre of box and lock, showing lock closed.
Figure III, external plan of lock, showing numbers marked near the circum-
ference of both discs and also on the outside of circle marked on the cover of
lock.
Any number of figures or marks may be made.
This lock can be opened easily by anyone knowing the combination of nunibers
or other marks. A combination may be arranged so as to puzzle any person not in
possession of the proper combination, and even then without a knowledge of the
principle of construction their effort will be futile.
To open the lock, set the combination of numbers, then turn the box upside down,
so that the bolt (G) will drop into the disc (A), and while the box is still upside
down, upset the combination, the bolt (G) will then remain in the disc (A); the
cover (C) can then be drawn outwards, so that the bent catch (CI) is clear of the
hole shown in Figure I at (CHI)..
The box can be used like an ordinary box with catch, by retaining the bolt (G)
in the disc (A). All that is necessary to lock the box, is to set the combination of
numbers and the bolt (() drops. All the parts are to be made of metal and of
such suitable size and shape, as will suit the strength of any kind of metal and
which will come within the scope of my invention.

page_text: 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. The drop bolt, and parts in which it works, as herein described.
2
Retention of bolt (G) in disc (A).
