Scaled the 19th April 1872, and dated the 23rd February 1872.
PROVISIONAL SPECIFICATION left by the said Joseph Quick, the elder,
and Joseph Quick, the younger, and Arthur Cooper at the Office of
the Commissioners of Patents, with their Petition, on the 23rd
February 1872.
We, JOSEPH QUICK, the elder, and JOSEPH QUICк, the younger, both
of No. 6, Westminster Chambers, Victoria Street, Westminster, in the
County of Middlesex, Civil Engineers, and ARTHUR COOPER, of Twicken-
ham, in the same County, Gentleman, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN SIGNAL LANTERNS OR LAMPS," to
be as follows:-
This Invention has for its chient improvements in signal lanterne or

page_text: lamps, and is designed to prevent mistakes in signalling by indicating to
the railway guard, signalman, or other person using or having charge of
the lantern or lamp, the color of the light or signal that is being dis-
played for the time being by the lamp, for which purpose we construct
or provide the lantern or lamp with a reflecting or other indicating
surface or surfaces, which may be formed with or attached to the
lantern case, door, or frame, or the external surface of the bull's eye
frame or case of the lantern may be adapted to form the indicating
surface.
The indicating surface or surfaces, according to our Invention, is or
are arranged in position for receiving some of the rays from the flame or
light used for making the required signals, which rays are projected
against or caused to impinge upon the said surface or surfaces which by
their position and arrangement will indicate to the operator or person in
charge of the lantern or lamp the color or character of the signal that is
being displayed.
When the indicating surface or surfaces is or are arranged on the
bull's eye case or frame, or otherwise externally of the main casing of
the lantern or lamp, we form or provide an aperture or apertures in the
main casing, frame, or door, which aperture or apertures may be glazed
or closed by suitable transparent material, through which the necessary
rays of light are projected on to the indicating surface or surfaces, being
first caused to pass through the colored glass or other coloring medium
employed when shewing a colored light.
In constructing hand signal lanterns or lamps with internal rotating
frames suspended to spindles having pins or projecting parts and passing
through guides provided with recesses to receive. and retain the pins or
projecting parts of the spindles in the proper positions for making the
required signals, we curve or incline the sides of the recesses so that on
turning the spindles their pins or projecting parts may readily travel
over the intervening projections from one recess into another without
its being necessary for the operator to raise the spindles for that
nurnose

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of February, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Joseph Quick, the elder, Joseph Quick, the
younger, and Arthur Cooper, Her special licence that we, the said
Joseph Quick, the elder, and Joseph Quick, the younger, and Arthur
Cooper, our executors, administrators, and assigns, or such others as
we, the said Joseph Quick, the elder, Joseph Quick, the
and
younger,
Arthur Cooper, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 SIGNAL LANTERNS OR LAMPS," upon the condition
(amongst others) that we, the said Joseph Quick, the elder, Joseph
Quick, the younger, and Arthur Cooper, our executors or administrators,
by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, 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 Joseph Quick, the younger, on
behalf of the said Joseph Quick, the elder, myself, and the said Arthur
Cooper, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and

page_text: ascertained in and by the following statement thereof, and the Drawings
therein referred to :-
This Invention has for its object improvements in signal lanterns or
lamps, and is designed to prevent mistakes in signalling by indicating
to the railway guard, signalman, or other person using or having charge
of the lantern or lamp, the color of the light or signal that is being
displayed for the time being by the lamp, for which purpose we construct
or provide the lantern or lamp with a reflecting or other indicating
surface or surfaces, which may be formed with or attached to the lantern
case, door, or frame, or the external surface of the bull's eye frame or
case of the lantern may be adapted to form the indicating surface.
The indicating surface or surfaces, according to our Invention, is or are
arranged in position for receiving some of the rays from the flame or
light used for making the required signals, which rays are projected
against or caused to impinge upon the said surface or surfaces, which by
its or their position and arrangement will indicate to the operator or
person in charge of the lantern or lamp the color or character of the
signal that is being displayed.
When the indicating surface or surfaces is or are arranged on the
bull's eye case or frame, or otherwise externally of the main casing of
the lantern or lamp, we form or provide an aperture or apertures in the
main casing frame or door, which aperture or apertures may be glazed
or closed by suitable transparent material, through which the necessary
rays of light are projected on to the indicating surface or surfaces, being
first caused to pass through the colored glass or other coloring medium
employed when showing a colored light.
In constructing hand signal lanterns or lamps with internal rotating
frames suspended to spindles having pins or projecting parts and passing
through guides provided with recesses to receive and retain the pins or
projecting parts of the spindles in the proper positions for making the
required signals, we by preference curve or incline the sides of the
recesses, so that on turning the spindles their pins or projecting parts
may readily travel over the intervening projections from one recess into
another without its being necessary for the operators to raise the spindles
for that purpose.
Fig. 1 is a vertical section taken in the line A, B, of Fig. 2, of a
lantern embodying our Invention.

page_text: Fig. 2 is a section taken in the line C, D, of Fig. 1.
Fig. 3 is an enlarged front view of the spindle and tubular guide
attached to the lantern top.
Fig. 4 is a section taken in the line E, F, of Figs. 1 and 5; and Fig. 5
is a side elevation of a part of the lantern.
The lantern a is provided with a glass a¹, lamp b, and reflector c. The
inner frame or casing d is made with an unglazed opening d¹ for showing
a white light, and is provided with two colored glasses d³, d³, one of
which may be red and the other green, but these colors may be varied,
and more than two different colors may in some instances be employed.
The frame or casing d is suspended by the cross piece e to the spindle f,
passing through the tubular guide g fixed in the top of the lantern a, as
shewn. The spindle fis provided with a handle f¹ and a screwed pin f*
which works upon the top of the guide g. This guide is formed with
three recesses to receive and hold the pin f in the proper positions for
making the required signals. This arrangement of signal lantern is
constructed according to the Invention for which Letters Patent,
No. 1443, dated 31 May 1871, were granted to Soloman Elsner.
h is the indicating surface with which we provide the lantern, ac-
cording to our Invention, for indicating to the railway guard or other
person using the lantern or lamp the color or character of the light or
signal that is being displayed. The face of this indicator is by preference
japanned white in the ordinary way.
We form apertures i in the door of the lantern, as shewn, and these
apertures are glazed or closed by a sheet of glass or other transparent
material k, through which the necessary rays of light from the flame x
are projected on to the indicating surface h, after having passed through
the unglazed opening d', when a white light is being shewn, or through
one or other of the colored glasses d³, d³, when a colored light is being
shewn.
The operator holds the lamp by its handle a³, and makes the desired
signals by slightly turning the handle f¹ so as to bring either the un-
glazed opening d' or the colored glasses & or d³, as the case may be,
opposite to the glass a¹ of the lantern.
It will be obvious that the application of our Invention is not confined
to the precise construction of signal lamp shewn in the Drawings.

page_text: Having described our said Invention of "Improvements in Signal
Lanterns or Lamps," and having explained the manner of carrying the
same into practical effect, we claim as the Invention secured to us by
the herein-before in part recited Letters Patent, the arrangement and
construction of signal lanterns or lamps with indicating surfaces for
indicating to the operator or user the color of the light that is being
displayed as above described
In witness whereof, I, the said Joseph Quick, the younger, have
hereunto set my hand and seal, this Twenty-first day of August,
in the year of our Lord One thousand eight hundred and seventy-
two.
JOSEPH QUICK, JUN³. (L.S.)
