power, sole privilege and authority, that I, the said William Thomas, my
exors, adñors, and assigns, or such others as I, the said William Thomas,
my exors, adiñors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, the Invention of "CERTAIN
IMPROVEMENTS IN FRAMES, LOCKS, AND FASTENINGS FOR CARPET BAGS AND PURSES,
PARTS OF SAID IMPROVEMENTS BEING APPLICABLE TO OTHER LOCKS," communi-
cated to me from a Foreigner residing abroad, in which said Letters Patent
is contained a proviso that I, the said William Thomas, shall cause a parti
cular description of the nature of the said Invention, and in what manner
the same is to be performed, to be inrolled in Her said Majesty's High Court
of Chancery within two calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Thomas, do hereby declare that the nature of the said Invention, and

page_text: the manner in which the same is to be performance and ascer
tained in and by the following statement thereof, reference being had to the
Diawings hereunto annexed, and to the figures and letters marked thereon,
that is to say
-
These improvements consist,―
First, of improvements in locks and fastenings for carpet bags.
Secondly, of improvements in the frames of carpet bags. And,
Thirdly, the Invention consists of constructing locks other than those used
for carpet bags, according to part of the improvements before mentioned.
And in order that the Invention may be fully understood and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figures 1, 2, and 3 are three views of one of my improved frames, shewing
the manner of constructing it Figure 1 is a front elevation of the frame
when folded together. Figures 2 and 3 are sections of the same, shewing the
manner of hanging the two inner frames to the outer frame, so that the two
inner fiames (when folded) will come within the thickness of the outer fiame.
A, A, A, A, is the outer frame, the shape of which is clearly shown (in
Figure 1), which I shall call the main frame, and it is very similar to those
before used B, B, B, is the first inside frame, and (C, C,) is the second inside
fiame or we, these last-named fiames B and C, when closed, pass within the
outer frame A, and, when folded, have no parts projecting beyond the surface
of the main fiame The inner frame or wire C is bent at each end, as shown
The hinge joint at each side has
may be in the frame A, so as to
in Figure 1, to form the pin of the hinge.
an elongated hole in the inner frame B, or it
allow of play, the object of which I will now describe.
By reference to the sectional view, Figure 4, the peculiar catch used to
fasten the ends of the bag fiame will be clearly seen when the parts A and B
are locked together. This catch is shown at F, F, one of the parts of which
is rivetted into the outer or main frame A, and the other into the inner fiame
B, B; and it will be evident that, owing to the elongated openings through
which the axis of the hinge passes, the frame B will be able to rise and fall,
and, owing to the form of the catches F, F, when the fiame B is raised, the
catches will take into each other, and as long as the frame B is upheld by
being locked to the frame A, the catches F will hold the parts A and B
together. And the lock (which is shown separately at Fig. 5, 6, 7, 8, & 9) 1s
so formed that in shutting the staple or hasp B fastened to the frame 'B'into
the lock fastened to the frame A, the frame B will be caused to rise, and on

page_text: '
unlocking the lock and withdrawing the staple or hasp therefiom, the fiame B
will descend, and thus release it from the catches F, and although 1 piefer a
lock made according to the first part of the Invention, I do not confine myself
thereto, as other constructions may be used when employing the catches F.
The mode of lifting up the frame is by the action of an inclined plane A¹
within the lock, and the hasp or staple of the lock coming against such
incline rises up, and then the shooting of the bolt by the key causes the staple -
or hasp to be held secure, and the catches F will retain the ends of the frame
from separating The peculiar character of the lock shown as applied to this
frame consists of its being made for and having an expanding key, the bit of
the key expanding during the operation of turning the key on the key pin of
tho lock This is effected by means of an excentric, which acts on the move-
able bit of the key. The construction of the key will be seen by reference to
Figures 10, 11, and 12; Figures 10 and 11 shews the shape of the key when
entering the keyhole, the sliding or expanding bit will at that time be close up
to the pipe of key, the key will therefore readily enter the keyhole, and a
small pin K, fastened into the excentric 1ng II, will enter a small hole in the
expanding bit of the key, hence it will be evident that by turning the key in
the lock the bit will be expanded and come against the tumbler and act on
the bolt of the lock.
By this arrangement of lock it will be evident that great difhculty will be
offered to the same being picked, as the key which will open it will not only
require to conrespond correctly with the tumblers and parts of the lock, but at
the same time it must be an expanding key capable of entering the small
keyhole used.
I would remark in respect to this part of the Invention, that I do not
confine myself to the arrangement of tumbler and parts shown of the lock, as
the same may be greatly varied, so long as the lock is made suitable for
receiving and expanding a key made capable of being expanded, as it should
be understood that the peculiarity of this lock is the circumstance of its being
arranged to receive and expand a key capable of being expanded, and I make
no claim to any lock or parts of a lock, unless the same is arranged suitable
for receiving and expanding a key.
Figures 13, 14, and 15 are three views of another improved bag framo
constructed of round metal, or it might be of another section of bar, the
inner frame of which is hung in the same manner as before described, so that
it may rise and be fixed by catches somewhat similar to those before explained,
and, owing to the outer and inner frames being'made of bars, the inner fiame
comes under the outer frame, which offers not only a great convenience, but

page_text: the cost of making this description of frame is less than when hoop iron is
employed, and the inner and outer fiames shut against each other.
Figures 16, 17, 18, and 19 show two other forms of bag frames for single
bags, where the clongated hole is in the outer frame A, allowing the inner
frame sufficient play up and down to bring the inner frame up into the hollow
recesses of the outer fiame, in which case the catches before described will not
be required, as the rising of the inner frame into the outer frame will, when
the two are locked together, prevent the inner one being opened at the ends
without the catches.
I have not thought it necessary to show a bag or a puise, as this part of
the Invention only relates to the frames for the same, and a workman from
the above description, aided by the Diawing, will readily make the frames of
the sizes described
In Figures 20, 21, and 22, I have shown two inside views and a cross
section of a door lock, according to the Invention In what are called
tumbler locks, at present in use, the tumblers being so close upon the key hole,
a false instrument may be readily introduced to the lock so as to reach the
paits and open the lock, to prevent which, and to give greater security, is the
object of the present improvement in locks, which object is fully obtained in
the following manner Fust, by the bit of the key being elongated while
acting on the tumblers; secondly, by the revolving box, which is carried round
by the key and completely closes the keyhole; and, thudly, by the pressure
tumble. The elongation of the key bit is produced, as before described, by
means of a revolving ng c placed so as to evolve eccentrically with respect
to the pin d or centre of motion of the key. This ng has a stud e, which
enters the moveable pait a of the bit. The key being put into the lock
canes the ring c and box 6 round with it, and the ing in its revolution with
the key forces out the pait a of the bit to its full extent, as shewn at Figures
25 and 26, thus will an elongated bit be obtained to the key while the key-
hole remains of the ordinary size. While the key is in action the keyhole is
entirely shut up, and when the key is out of the lock the works are protected
from being acted upon through the keyhole And in order to obtain gicater
security to the lock an extra pressure tumbleı k is introduced
This pressure
tumbler is attached to the bolt by a stud g, as shewn, and moves along with
the bolt in the act of locking and unlocking. It has also a vertical motion
given to it by the key along with the other tumblers. 2 is a stump fixed into
the pressure tumbler k, which, when the bolt is in the locked position, stands
close by the end of the other tumblers, as seen in Figure 22. The ordinary
tumblers have a groove r in them, through which the locking stump h (affixed

page_text: to the bolt) passes in the act of locking and unlocking. In the act of un-
locking, all the tumblers being elevated to their proper position by the key,
the stump i in the pressure tumbler passes through the grooves formed in the
ordinary tumblers, and the locking stump h which is fixed in the bolt passes
through the grooves ?. The ordinary tumblers have projections on the end of
them which, when any pressure is put upon the bolt, the stump i in the
pressure tumbler enters between and presses on the end of the tumblers so as
to prevent the tumblers q being clevated.. The same letters refer to the same
parts in all the Figures.
Figures 23 and 24 is a side view and an end view of the key in the
state it should be when inserted in the lock, and Figuros 25 and 26 show it
when the bit is forced outwards; Figure 27 shows an end view of the key
with the part a removed, and Figures 28, 29, and 30 show the part a sepa-
rately. a' is a hole or recess in the part a, into which the stud e of the
eccentric ring centers. Figure 20 is a view of the interior of the lock,
showing the pressure tumbler k with its stump i. is the stump fixed into
the bolt 2, with the corresponding opening in the pressure tumbler. m is a
spring, one end of which is affixed to the tumbler, and the other end presses
against the stud n on the bolt 7, so as to cause the reaction of the tumbler on
the key. All the other tumblers are removed in this view, and likewise the
revolving box b, which is shewn separately at Figures 31 and 32 in order that
some of the parts may be better understood. f is a spring which is pressed on
by the key at the time of its being inserted into the lock; and this sping f
is for the purpose of retaining the parts b and c from turning except when
acted upon by the key. Figure 22 is a view of the interior of the lock (the
covering plate only being removed) in the position when the bolt is thrown
outwards
It will be evident from the above description that the construction of lock
to which these improvements are applied may be varied, I do not, therefore
confine myself to the details shewn and described, so long as locks are made
the parts of which are suitably arranged for receiving and expending a key
suitably constructed for being expanded, as herein explained And I would
wish it to be understood that what I claim is,—
First, the arranging of locks for the frames of bags and purses, as herein
descubed, whereby the parts are so constructed and combined as to receive
and act on and with an expanding key, as herein explained.
Secondly, I claim the mode of arranging frames for bags and purses,
whereby the inner fiame and outer frame, by moving in respect to each other,
are caused to be fastened together by catches F, F. or by the inner frame

page_text: coming within the outer frame, as above explained. And I also claim the
former of the inner and outer frames, whereby the inner frame shuts under
and not against the outer fiame, as above explained. And,
Thirdly, I claim the so arranging of locks for doors, and other places, as
herein described, whereby the parts are so constructed and combined as to 5
receive and act on and with an expanding key, as herein explained.
In witness whereof, I, the said William Thomas, have hereunto set my
hand and seal, this Fifteenth day of September, in the year of our
Lord One thousand eight hundred and forty-six.
