APPARATUS FOR COLLIERY AND OTHER PURPOSES.
"
Sealed the 29th June 1866, and dated the 3rd January 1866.
PROVISIONAL SPECIFICATION left by the said William Buckley at
the Office of the Commissioners of Patents, with his Petition, on the
3rd January 1866.
I, WILLIAM BUCKLEY, of Tankersley, in the County of York, Mechanic,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SIGNALLING APPARATUS FOR COLLIERY AND OTHER PURPOSES," to be as
follows:-
This Invention relates to a peculiar arrangement and combination of
mechanism for transmitting signals in colliery and other mines from the
bottom of the shaft to the surface, or for signalling for other purposes, and
consists in the employment for that purpose of a metal base plate, which is
secured to a small or other convenient support, and is provided with two
fixed studs or centre pins, upon the first of which is fitted to play freely a
grooved pulley, round which the signalling chain or cord passes, and whence
it descends to the bottom of the mine shaft. A stud or lateral projection
on the boss of this pulley works in a curved slot in the base plate, and
thereby controls the rotatory motion of such pulley. On one side of the

page_text: periphery of this pulley there is cast a pocket or recess, which receives a
tumbler for elevating the spring-striking hainmer of a signal gong fixed on
the same stud that carries the grooved pulley. The second fixed stud or
centre pin in the base plate serves as the fulcrum of the lever which carries
the hammer, and upon this stud there is also fitted so as to turn freely a
disc having two apertures made therein on diametrically opposite sides near
its circumference. This disc receives a step by step rotatory movement
by means of a pall in the hammer lever taking into a ratchet wheel on the
centre of the disc, so that each time the hammer is elevated by the action
of the tumbler against a projecting portion of its lever the disc will be
moved through a certain space. Behind this disc on the surface of the
base plate there are painted or engraved a series of numbers, so arranged
that those numbers only will be visible which coincide with the perforations
in the disc. The object of this disc and the numbers behind it is to serve
as a register by indicating the number of signals given during the absence
of the attendant.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Buckley in the Great Seal l'atent Office on
the 3rd July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BUCKLEY, of Tankersley, in the County of York, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of January, in the year of our
Lord One thousand eight hundred and sixty-six, in the 29th year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Buckley, Her special license that I, the said
William Buckley, my executors, administrators, and assigns, or such
others as I, the said William Buckley, my executors, administrators, or
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might 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 SIGNALLING APPARATUS FOR COLLIERY AND OTHER
PURPOSES," upon the condition (amongst others) that I, the said William
Buckley, my executors or administrators, by an instrument in writing

page_text: under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be.
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William Buckley, 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, reference being had to the accompanying Drawings,
and to the letters and figures marked thereon, that is to say :-
My said Invention relates to a peculiar arrangement and combination of
mechanism for transmitting signals in collieries and other mines from the
bottom of the shaft to the surface, or for signalling for other purposes.
Fig. 1 of the annexed Sheet of Drawings represents a side elevation of
my improved signalling apparatus, and Fig. 2 is a corresponding edge view
of the same.
A is a metal base plate which is secured to a wall or other convenient
support, and is provided with two fixed studs or centre pins B and C, upon
the first of which is fitted to play freely a grooved pulley D, round which
the signalling chain or cord passes, and whence it descends to the bottom
of the mine shaft. A stud or lateral projection E on the base plate works
in a curved slot F in the boss of the pulley D (shown in dotted lines in
Fig. 1), and thereby controls the rotatory motion of such pulley. On one
side of the periphery of this pulley there is cast a pocket or recess G,
which receives a tumbler H for elevating the spring-striking hammer I of
a signal gong K, fixed on the same stud that carries the grooved pulley D.
The second fixed stud or centre pin C in the base plate serves as the
fulcrum of the lever L which carries the striking haminer I, and upon this
stud there is also fitted so as to turn freely a disc M, having two aper-
tures a, b, made therein on diametrically opposite sides near its circum-
ference. This disc receives a step by step rotatory movement by means of
a pall N jointed to the hammer lever, taking into a ratchet wheel O on the
centre of the disc, so that each time the hammer is elevated by the action
of the tumbler H against a projecting portion of the lever L, the disc M
will be moved through a certain space. Behind this disc on the snrface of
the base plate A there are painted or engraved a series of numbers (see
Fig. 1), so arranged that those numbers only will be visible which coincide
with the perforations in the disc. The object of this disc and the numbers
behind it is to serve as a register by indicating the number of signals given

page_text: during the absence of the attendant. P is a blade spring for producing
the blow of the hammer after it has been elevated and released by the:
tumbler H, which tumbler on its return to its former position, or during,
the backward partial rotation of the pulley D, falls into and is enclosed by
the pocket or recess G in the periphery of the pulley. If desired a balance
weight may be so attached to the disc M as to bring it back again to zero,
where the click or pall N is raised out of the ratchet wheel O, which may
be effected either by the attendant or by the machinery so as to commence
with unity every time it is desired to give a signal. In lieu of the perfo-
rated disc it is obvious that a finger or index pointer may be employed, and
if desired the signalling apparatus may be made without the registering
part.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect,. I would observe in conclusion, that what I consider to
be novel and original, and therefore claim as the Invention secured to me
by the herein-before in part recited Letters Patent, is,
First, the combination in a signalling apparatus of the tumbler H with
the pulley D, lever L, hammer I, and gong K, operated by a cord or chain
substantially as herein-before described.
Second, the combination with the above of the disc or indicator M,
ratchet wheel O, and pall N, the whole being arranged and operating sub-
stantially as and for the purpose herein-before described.
In witness whereof, I, the said William Buckley, have hereunto set
my hand and seal, the Twenty-eighth day of June, One thousand
eight hundred and sixty-six.
WILLIAM BUCKLEY. (L.S.)
