Improvements in Locking Devices.
I, FRANCIS JOSEPH JAMES GIBBONS of St. John's Works, Church Lane,
Wolverhampton, in the County of Stafford, Lock Manufacturer, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in locking devices and consists in
combining with each part to be locked to another one, of an eyed lug, all the lugs
being capable of being aligned as to their eyes when the parts are in the position
to be locked, and a special locking device variable as to some of its features but
comprising a bolt adapted to hold the lugs in the locked position by being passed
through them all excepting the last, or through one only when there are only
two, and screwed into the last one, or into the other of the two, as the case
may be.
Tampering with the locking device when it is in the locked position is prevented
by the adoption of any suitable device. My invention does not limit me in this
respect for the constructional details of such a device are capable of considerable
variation.
One device consists of a suitable block from which a bolt is protruded by
unscrewing a key off or from the opposite and concealed end thereof. The
protruded end of the bolt receives a rotary motion during the time of its protrusion,
from the act of removing the key from the block.
Or I may fit any suitable type of puzzle lock to be worked by a loose key,
upon the top of the bolt, the key being adapted to engage in a correspondingly
shaped socket in the head of the bolt, or to otherwise engage with it, when it has
passed the puzzle part of the lock. Such puzzle part may consist of an internal
diaphragm having the key hole in it set at an angle with that in the outer plate of
the lock.
Instead of an internal diaphragm, I may provide for the head of the bolt to be
held to it by means of a ratchet device when such head is turned in the proper
direction for screwing the bolt into the screw threaded lug, which ratchet device
disengages from the shank of the bolt when the head is turned in the opposite
direction. The shank is reached, under such circumstances, by a loose key which
is passed through the head and engaged in a corresponding cavity in the head of
the shank.
Any of the devices above mentioned may be modified or combined with each other
as may be desired.
Dated this 27th day of November 1894.

I, FRANCIS JOSEPH JAMES GIBBONS of St. John's Works, Church Lane,
Wolverhampton, in the County of Stafford, Lock Manufacturer, 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:—
My invention relates to improvements in lock devices and consists in combining
with each part to be locked to another one, of an eyed lug, all the lugs being
capable of being aligned as to their eyes when the parts are in the position to be
locked, and a special locking device variable as to some of its features but
comprising a bolt adapted to hold the lugs in the locked position by being passed
through them all excepting the last, or through one only when there are only
two, and screwed into the last one, or into the other of the two, as the case
may be.
Referring to the accompanying drawings which are to be taken as part of this
Specification and read therewith.
Figure 1 is a side elevation of a safety bicycle with its steering head locked to
the stalk of the front fork.
Figure 2 is a part sectional elevation on an enlarged scale taken on the line 2-2
of Figure 1, and illustrating the internal construction of one modification of the
present invention.
Figure 3 is a sectional plan taken on the line 3-3 of Figure 2 after the removal
of the locking device.
Figure 4 is a side elevation of the locking device and key separate from each
other.
Figure 5 is a plan of the socketted head of the bolt of the locking device.
Figure 6 is a sectional elevation of a modified locking device.
Figure 7 is a part sectional elevation of the same locking device and key
separate from each other.
Figure 8 is an elevation of the same locking device.
Figure 9 is an inverted plan of the ratchet disc.
Figure 10 is a plan of the head of the bolt of the same locking device.
Figure 11 is a plan of the locking device.
The improved locking device consists of an eyed lug which is the equivalent
of the staple or shackle of an ordinary lock, a bolt adapted to be engaged there-
with or disengaged therefrom by a special movement, a key, a special engagement
between key and bolt, and a cap.
a, a are the two eyed lugs, one of which is to be locked to the other. They
are, for that reason, so positioned upon the separately moveable parts of which
they are respectively extensions, and with which they are incorporated, that they
can be readily aligned or made to register the one with the other, both lugs then
standing close together or nearly so.
I have selected the application of my invention to a bicycle lock for illustration,
the above mentioned separately moveable parts being the two collars b, 61, one
of which is fast to the steering head and the other to the stalk of the front fork
as heretofore.
There may be more than two eyed lugs each one fast to its respective separately
moveable part, held by one locking device, but the invention is not operative with
less than two. Beyond this limitation, the number of eyed lugs is not a feature of
the invention and does not affect the nature of it. In any case the construction of
the invention as well as its action are the same whatever the number of lugs above
two may be.
c is the bolt of the locking device. It is a round rod of a length conveniently in

page_text: excess of the joint thickness of all the eyed lugs to be dealt with.
The eye of the
lug al to which the other (or others) is to be locked, is screw threaded and the en!
of the bolt c is screw threaded too, to engage in it. The eye of the other lug a or
those of all the other lugs, may be plain and of the same diameter as the rod of the
bolt c, or it, or the outer one of the said others, may be of the same diameter and
screw threaded, the bolt c being screw threaded far enough from its nose to allow of
it engaging in both the screw threaded eyes. The second screw threaded eye is
thereby adapted to serve as a socket in which the locking device can be held by it
bolt when itself is, as such out of use.
d is the head of the bolt. It is fast thereupon after the manner of bolt heads and
incapable of independent motion.
The bolt d is provided with a special key for locking and unlocking it, and, further,
with a special device for preventing tampering with it (the said bolt), especially when
it is locked.
According to the modification illustrated in Figures 1 to 5, the key is webbed
and consists of a milled head e, a shank e¹ and a one wheel bit e².
The nose
of the shank is continued past the web being thereby adapted to enter a
socket of a suitable depth bored downwards axially into the bolt head d.
e is a circular slot likewise in the bolt head d and concentric with the socket e³.
It is adapted in respect of size and position to receive the bite which then
engages the said head by bearing against one or the other of the closed ends of
the slot et.
is a cap.
It surrounds the bolt head on all sides (subject to the presence of a
key hole mentioned further on) being made fast to the said head in such a way
that it can be turned freely about the axis of it without engaging with it and
yet cannot be detached from it even to the extent of submitting any part of
it to inspection or to the risk of being got at beyond what can be effected in the
way of either, through the key hole. is this key hole and f2 is the key hole
plate or bush in which it is made. This plate or bush is the closing top of the
cap f. It is made fast to the cap f and is incorporated with it without the provision
for turning independently.
The locking device constructed as above described, is used to lock the lugs together
by being first passed through all but the bottom one, by means of the key, and by
having the front end of the bolt c afterwards screwed, by means of the same key,
into the eye of the bottom lug a².
с
According to the modification illustrated in Figures 6 to 11, the loose key is
capable of only unlocking the device from the lug a-it is the cap that is the
locking agent.
f is the cap.
It is connected to the bolt c on exactly the same plan as in the
modification already described. d is the bolt head. f is the cap plate of the
cap and is fast to it without the capacity for independent circular motion as is
also described with reference to the cap plate f of the previous modification.
f* is a pawl or tooth on the under side of the plate f³, adapted to engage in the
angular notch f in the bolt head when the cap is turned in the proper direction
for entering the nose of this bolt c into the lug a' and to slip over the said notch
when the cap is turned in the reverse direction. The tooth f' and the notch f'
constitute a ratchet, the motion of engagement and that of disengagement being
provided for a vertical play between the cap f' and the bolt head d indicated by the
clear space g shewn in Figures 6 and 7. When the cap f¹ is turned to follow the
lead of the screw thread on the bolt c, the tooth f engages in the notch f' and turns
the bolt with it. When the cap is turned in the direction opposite to that of the
said screw thread, the tooth f slips over the notch f' and the bolt c is not turned.
The constructional details of the ratchet device just described may be varied to any
extent provided that the due discharge of its functions as they are specified above, is
secured.
The key consists of a screw g¹ having a milled head g². It engages with the bolt c
by being entered into a socket g³ bored down axially into the bolt c, which socket is

page_text: screw threaded to receive it. The screw threads in the socket g³ and on the key g'
are of the opposite hand to those of the eyed lug a¹ and bolt c. Consequently, the
motion of engaging the key g' with the bolt c, will, if continued unscrew the latter
from the lug a. is a hole in the centre of the plate f³ to admit of the passage
of the screw g in either direction.
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 :-
1. The hereinbefore described improved locking device, as set forth.
2. The combination of bolt, bolt head, cap and key adapted to engage with a
corresponding groove or socket in the bolt head, as set forth.
3. The combination of bolt, bolt head, circular slot therein, and bitted key, as
set forth.
4. The combination of screw threaded bolt with key and key socket screw threaded
to the opposite hand, as set forth.
