page_text: I, SIDNEY WHARTON, of 100, Bearwood Road, Smethwick, Birmingham, in the
County of Warwick, Foreman, do hereby declare the nature of my said invention
to be as follows:-
My invention has for its object an improved lock which is specially applicable
for locking a clip, chain or the like to cycles but can with equal advantages be
used for other purposes..
In carrying my invention into practice I mount a drum formed in two parts on
a spindle one half of which is fixed on the spindle the other half being free to
revolve thereon and having a collar or boss formed on its centre. This drum is
then fitted into another drum or outer case having a hole in its centre through
which one end of the spindle and the boss on the centre of the semi drum pass
and are free to revolve therein. I then fix a hand or pointer,--say a long hand
similar to the minute hand of a clock-onto the end of the spindle which pro-
trudes through the centre of the outer case and another hand or pointer-say a
short hand similar to the hour hand of a clock-onto the boss of the semi drum
which also protrudes through the centre of the outer case, and on the side of the other
case I form or fix a clock dial. In the rim or periphery of the outer case I form
a round, square or other shaped hole and a corresponding hole in the rim or
periphery of the drum into which a catch or the like fits. It will thus be seen
that when the hands on the outside of the case are moved that the semi drums
will be moved also thus moving the hole in the drum into which the catch fits
away from the hole in the outer case thereby preventing the catch from being
withdrawn. This catch may be fixed to one end of a clip or to one end of a chain
or the like, the other end being fixed to the outer case. To release the catch the
hands must be moved so as to point to a predetermined time on the dial which
movement brings the hole in the periphery of the drum opposite the hole in the
outer case.

County of Warwick, Foreman, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:

hands must be moved so as to point to a predetermined time on the dial which
movement brings the hole in the periphery of the drum opposite the hole in the
outer case.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of my lock.
Figure 1 is a view of one form of my lock complete.
Figure 2 is a plan view of Figure 1.
Figure 3 is a part sectional view of Figure 1.
Figure 4 is a view of the internal glauged dises shewing the opening for releas-
ing the catch.
Figure 5 is a plan view of Figure 4 shewing the D shaped holes in the centre of
the same.
.
Figure 6 is a plan view of the central disc or plate.
Figures 7, 8, 9, & 10 shew modifications of my invention on a reduced scale.
In carrying my invention into practice I mount the semi drums A and A¹ or
their equivalents on the spindle S which is formed with a flat on one side. The
semi drum A¹ is formed with the D shaped hole a² in its centre for the end of the
spindle S to fit into so as to prevent it turning on the spindle, and with the
notch a³ or its equivalent on the edge. The other semi drum A is also provided
with the D shaped hole a in its centre for the hollow sleeve B or its equivalent

page_text: which is formed with a flat on one side to fit into, and with the notch a or its
equivalent on the edge corresponding with the notch a³ formed on the edre of the
semi drum A. The division plate E which fits onto the spindle between the semi
drums provided so as to hold the semi drums the required distance apart and is
formed on one side with the lip or projection & and on the other side with the
notched part in the centre of which the projection e³ is formed. A hole is also
formed in the centre of this division plate for the spindle S to pass through. These
parts are then fitted into the outer case or cover F the alot being formed in one
side of this case for the projection e¹ on the division plate to pass through and the
hole or slot preferably in the opposite side of this case or cover for the catch h¹
which is attached to the link or chain H to pass through the other end of this link
or chain being attached to the projection of which protrudes through the side of
the outer case. On the front or face of the outer case I form or fix a clock dial
or the like. The semi drum A is first fitted into the outer case and then the
division plate E and afterwards the other semi drum A¹. The hollow sleeve B
which is provided with the short hand or pointer 6' similar to the hour hand of a
clock is now fitted through the hole formed in the centre of the dial into the
D shaped hole in the seni drum A and lastly the spindle S which is also provided
with the long hand or pointer a-similar to the minute hand of a clock-is passed
through the sleeve B and through the D shaped hole in the semi drum A'. The
back of the case or cover is then fitted in position and the end of the spindle S
rivetted over or otherwise secured so as to firmly hold all the parts together. It
will thus be seen that when the hands on the dial are turned or moved that they
will operate or turn the semi drums A and A¹ and when these hands are moved so
as to point to any predetermined time on the dial the notches a³ and a in the
semi drums are brought opposite the opening f in the outer case or cover thus
allowing the catch h₁ on the end of the link or chain H to be inserted. This
catch his provided with a recess at the end which takes onto the projection e
on the division plate E as clearly shewn at Figure 3. If the hands and con-
sequently the semi drums are now moved in either direction the catch h¹ will be
locked or securely held between the said drums as clearly shewn at Figure 3. In-
stead of attaching the catch to the link or catch H it may be attached to a
clip or the like.
At Figures 7, 8, 9 & 10 I have shewn a slightly modified form of my lock. In
this case I form the semi drum A' with the collar or boss a' in the centre which
is drilled and tapped to receive the screwed end of the spindle S the other semi
drum A is also formed with the collar or boss as through which the spindle passes
and is free to revolve therein. The hand or pointer 61 is fitted onto the boss as of
the semi drum A which protrudes through the hole in the dial of the outer case
or cover F and the hand or pointer is fitted onto the end of the spindle which
passes through the boss as as clearly shewn at Figures 7, 8 and 9. It will thus
be seen that when these hands are moved so as to bring the notches a³ and as
opposite the opening in the outer cover the catch h¹ can be withdrawn. The
eye piece h5 which is fixed to the opposite side of the outer cover is provided for
attaching the other end of the chain H or its equivalent to.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
CLAIMS.
First The improved lock consisting essentially of the semi drums such as A
and A¹ or their equivalents working in an outer case or cover the front of which
s formed with a dial the said semi drums being operated independently of one
nother by hands or pointers so as to hold or release a catch such as h¹ in the
nanner and for the purpose substantially as herein set forth and as shewn upon the
ccompanying sheet of drawings.

page_text: Second: In a lock which forms the subject of the first claim arranging the
notches such as a³ and a5 on the semi drums A and A¹ so that when the hands
are turned to point to a predetermined time the said notches are brought opposite
the opening in the side of the outer case thus releasing the catch in the manner
substantially as herein set forth and as shewn upon the drawings.
