Year: 1875

page_text: LETTERS PATENT to Joseph Kaye, of Kirkstall, near Leeds, in the
County of York, for the Invention of "IMPROVEMENTS IN THE MEANS
OR APPARATUS EMPLOYED FOR REGISTERING THE LOCKING OR UNLOCKING OF
Locks."
Scaled the 21st September 1875, and dated the 9th April 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Kaye at the
Office of the Commissioners of Patents, with his Petition, on tho
9th April 1875
I, JOSEPH KAYE, of Kukstall, near Leeds, in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MEANS OR APPARATUS EMPLOYED FOR REGISTERING THE LOCKING OR UNLOCKING
OF Locks," to be as follows:-
My Invention is particularly applicable to Kaye and Kaye's collecting
box, Patent No. 1005, 1874, whereby the conductors or other receivers
of money cannot unlock or lock the box without the knowledge of those

page_text: appointed to inspect them. It is also applicable to other purposes in
combination with a lock.
The lock may be of any design or construction, but is so arranged that
in turning the key in the lock a simultaneous movement is imparted to
the registering apparatus, which apparatus registers the number of times 5
the lock has been locked or unlocked.
In combination with the lock I employ a ratchet or equivalent motion,
which is actuated by the movement of the key, and transmits that move-
ment through suitable gearing in connection therewith to a dial or dials,
which is or are numbered The figures on the dial or dials having 1
arrived at a certain point represent the number of times the lock has
been locked or unlocked.
Any suitable [registering apparatus may be employed in combination
with the lock, movement being given thereto by turning the key, for
L
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Kaye in the Great Scal Patent Office on the
9th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
KAYE, of Kirkstall, near Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of April, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did for Herself, Her heirs and successors, give and
grant unto me, the said Joseph Kaye, IIer special licence that 1, 1
the said Joseph Kaye, my executors, administrators, and assigns, or
such others as I, the said Joseph Kaye, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therem, expressed,
should and lawfully mught make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE MEANS OR
APPARATUS EMPLOYED FOR REGISTERING THE LOCKING OR UNLOCKING or Locks,"
upon the condition (amongst others) that I, the said Joseph Kaye, my

page_text: Sheet 2 is a modification of lock shown on Sheet 1, in which Figure 1
shews the lock with outer case removed, Figure 2, an end elevation ; and
Figure 3, a plan.
I will now proceed to describe Sheet 1. I provide a lock having its
bolt a and tumbler of ordinary construction, but on the bolt a I
mount a pawl c, which is made to work into a ratchet wheel & within
the lock. By locking the bolt a or moving the bolt a in the direction of
arrow to dotted lines the pawl c is moved from its position shewn on
Drawing into the next tooth on the ratchet wheel d. When the bolt a
is unlocked or withdrawn it carries with it the pawl c, which being in
gear with the ratchet wheel & imparts to it a rotary motion, which occurs
every time the bolt a is unlocked or withdrawn. The pawl c is kept in
position by means of the spring e In order to prevent the ratchet
wheel & moving back as the pawl c traverses to the next tooth of the
ratchet wheel & I provide a catch, which is retained in gcar with the
ratchet wheel d by means of the spring g, and prevents the ratchet
wheel d from moving at any other time except when the bolt a is un-
locked or withdrawn On the same ratchet wheel shaft h, and on the
exterior of the lock is fastened a disc or dial plate 2, which is moved
simultaneously with the ratchet wheel d. Behind this disc or dial plate »
is provided a catch J, which as it moves (with the disc or dial plate 2)
one revolution it passes into one of the notches & in the plate 1, causing
the plate to move the distance from one notch % to another. Behind
the plate is provided another catch ', like that at J, which gears
into the notches m on the plate n. By this arrangement the plate n is
caused to move round the distance of one notch m to another every
revolution of the plate 7. In frout of these plates and n are provided
discs or dial plates o and p, similar to that shewn at ¿, on which are put
marked numerals, in a similar manner to those on ordinary gas meters.
Each disc or dial plate is provided with a pointer, as shewn at q, r, and s.
In the Drawing I have shown only three dials, plates, or discs, of which
2 represent units, o tens, and p hundreds. The number of these plates
or discs may be increased or decreased, as may be required. The number
of times the lock has been used can readily be ascertained by examining
the figures to which the pointers are directed, as, for instance, the lock
on my Drawing is supposed to have been used one hundred and eleven
times. A similar movement may be given to the dial plate or disc
when the bolt a is locked or moved outwards by reversing the teeth in
the ratchet wheel & and position of the pawl c and catch ƒ.

page_text: understood that I do not limit myself to the exact limits, details, or con-
figuration of the various parts I have explained and shewn, as the samo
may be varied or modified without in any way departing from my In-
vention, but what I do claim and desire to be secured to me by Letters
