IMPROVEMENTS IN LOCKS
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, London, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her.
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourth day of December, in the ninth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Moses
Poole, my exors, admiors, and assigns, Her especial licence, full power, solo
privilege and authority, that I, the said Moses Poole, my exors, adñiors, and
assigns, or such others as I, the said Mosès Poole, 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, and in the Islands of Guernsey, Jersey, Alderney, Sark,
and Man, and also in all Her said Majesty's Colonies and Plantations abroad,
my Invention of "IMPROVEMENTS IN LOCKS," communicated from abroad; in
which said Letters Patent is contained a proviso, that I, the said Moses Poole,
shall cause a particular 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
Iligh Court of Chancery within six 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
Moses Poole, do hereby declare that the nature of my said Invention, and the

page_text: Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an external view of a lock constructed according to the
Invention; Figure 2 shows a back view of the lock complete; Figure 3
shows another 'back view with some of the parts removed; Figure 4 is a
Hongitudinal section thereof; Figure 5 shows a transverse section; and Figures
6, 7, and 8 show some of the details separately, and also the key to be used.
a, a, is the case or frame of the lock, the nature of which is clearly shewn in
the Drawing; is the bolt of the lock; c is the handle of the bolt, which is
affixed to the bolt, and the stem of the handle slides in a slit formed in the
front of the case or frame a of the lock. The bolt is at all times pressed
outwards by a spring d. The bolt b is acted on in the following manner:-
e is a plate fixed in the inside of the lock, and through this plate the screwed
stem of what may be called the follower ƒ passes, and the cylindrical portion
of this: follower is received into a corresponding recess in the plate e, and turns
therein, the recess acting as a bearing for the follower. The arm f¹ of the
follower enters the notch formed in the bolt b, as is shewn, hence when the
follower is turned on its axis of motion the bolt b will be moved. Through
the centre of the axis of the follower is formed a hole, and at one side a
recess, and through this hole the .pin 7 passes, there being a crosshead g¹
affixed, and this crosshead is formed to fit the recess f in the follower; hence,
when the crosshead g³ is in the recess f the bolt cannot be slided or moved,
and this ping, and consequently the crosshead g¹, can be moved out of
the way by means of the key h or by incans of the lever i. The key h is
formed with a female screw to fit the male screw on the fallower, and the
interior of the key is so formed that it will come against the ping and push it
back into a proper position to allow the bolt b. to slide. j is a spring which
constantly presses the pin g into the follower, and therefore the pin will by its
crosshead retain the bolt from the sliding till the pin g is moved back, and
the key on being further turned will move back the bolt b. When it is
.desired that the bolt 6 should be free to be acted on by its handle, then the
lever i is to be folded down, as shown at Figure 1, and by dotted lines. at
Figure 4; by which means, owing to the form of the lever, the pin g to which
the lever is attached will be moved back by the lever, and as long as the
lever is folded down the bolt 6 will be free to be moved. It will be evident

page_text: to the locksmith, on examining the Figures of the Drawings, aided by the
description thereof above given, that the improvements shown may be applied
under different arrangements of locks, and that the details of the improvements
may be modified, such improvements consisting of the mode of constructing
and combining the follower with the pin g and parts connected therewith, to
be acted on by a suitable key. And I have in the Drawings shown two other
modifications of locks, materially differing from each other, yet similar in con:
struction in respect to the improvements, one to the other.
Figure 9 shows a plan and edge view of a padlock and parts connected
therewith; Figure 10 shows the back of the lock separately; and Figures
11, 12, 18, and 14 show the details separately, and also the key used there-
with. In this case what I have called the follower in the other lock acts as
the bolt. a is the case or frame; b are the bolts, fixed to the follower f, which
has a recess f for the crosshead of the pin g, which in this case is affixed to
the spring. The lock has two openings at back a, a, as shewn, through
which the staples k, k, pass, and the plate 1, being included between the lock a
and the plate. The whole will be held together till by the use of the key m
the pin m³ therein forces back the pin g, when the crosshead g¹ being moved
out of the way the further turning of the key will cause the bolts 6 to be
moved out of the staples.
Figure 15 shows a front view of another arrangement of lock made with
the improvements applied thereto. Figure 16 is a back view thereof; Figure
17 shows another back view with some of the parts removed; Figure 18 is a
longitudinal section; Figure 19 is a transverse section thereof; and Figures
20 and 21 shew some of the details separately, and also the key. In this
instance the key does not have a female screw formed therein, but only two
nebs or projections, which enter the screw formed in the stem of the follower;
and a spiral spring is used to act on the pin g in place of the flat spring, shown
at Figures 2, 3, and 5; and the key n in this instance has a pin therein to act
on the pin g.
The lock now under description differs in various respects in form and
construction from those before described, the parts which are similar being
marked with the same letters of reference as before used. The description
above given of similar parts will apply to the present lock, and the Drawings
will point out the other differences when aided by the observations here given.
In the present lock, as it is only intended to be opened on one side, there is
no handle to the bolt b, as in Figure 1, and the lever for acting on the pin g
is dispensed with.
Having thus described the nature of the Invention, and the manner in

page_text: which the same is to be performed, I would have it understood that I do not
confine myself to the details of construction of the locks to which the improve-
ments are applied; and the details of the improvements may be varied, so long
as the peculiar character of construction and combination of the parts be
retained. And I would have it understood that what I claim is, the mode
of constructing and combining the parts f and 9, and parts affixed thereto,
together with a suitable key, as above described.
In witness whereof, I, the said Moses Poole, have hereunto set iny hand
and seal. this First day of June, in the year of our Lord One thousand
