An Improved Apparatus for Reflecting Outlines for Advertising
Purposes.
PHILIP BAKER COOKE, Printer HOWARD COOKE Builder & Decorator, both
of 35, Lower Kennington Lane Lambeth in the County of Surrey, do hereby
declare the nature of this invention to be as follows:-
Its object is to reflect numerals, letter or any required outlines on walls, floors,
and ceilings, or on any suitable surface. In order to carry out this object we
In one side of this ball we
use a suitable hollow metal ball of any required size.
fix a suitable and powerful magnifying glass. The light to be used for reflecting
is placed immediately behind the glass, and inside the ball, and a suitable reflector
behind the light. The half of the ball opposite this glass is made to open being
hinged as a door. This glass is covered by a suitable telescope, provided with a
slot for inserting the glass on which the objects to be reflected is sketched. The
end of this telescope furthest from the ball is provided with an adjustable lens.
The light used for reflecting may be electric, gas, or any artificial light. In this
instance we use ordinary coal gas, which is supplied through a tube placed through
the bottom of the ball and connected with the burner. We provide for ventilation
by means of an aperture in the top of the ball which is covered by a cowl made
of any noninflammable material. This metal ball is supplied with two metal
pivots which are placed on the outside of the ball at opposite points, and in a line
with the centre of the ball and at right angles to the axis of the telescope. These
pivots are made to fit in sockets on suitable brackets, made suitably to carry the
whole of the apparatus here described. By this means the reflector from the lens
can be thrown on any required surface at any desired height.

COMPLETE SPECIFICATION.
An Improved Apparatus for Reflecting Outlines for Advertising
Purposes.
We, PHILIP BAKER COOKE, Printer and HOWARD COOKE Builder and
Decorator, both of 35 Lower Kennington Lane, in the County of Surrey, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
surfaces
Our invention relates to an improved apparatus for reflecting upon
situated at any angle relatively thereto, numerals, figures, designs or words for
the purposes of advertising goods for sale, or any other subject or matter desired.
The said apparatus in so far as regards its initial operation is based upon the
principle of an ordinary projecting optical lantern, but is so constructed as to be
adapted for fixing upon the outer or such other parts of business premises as will
enable the operator to project the advertisement placed therein, onto the part or
parts of the show window, ceiling, pavement or other adjacent place desired
without removing the apparatus as a whole when, once suspended and fixed in the
position desired.
The lantern part of the apparatus may be of any size, shape or configuration
desired, but we prefer that the same should be ball shaped or spherical, or may be
spheroidal, and with this in view we have chosen to illustrate our invention in

page_text: '
that form in the accompanying drawings, in which the three figures therein shewn
and numbered 1, 2 and 3, are side elevation, plan and vertical part section
respectively..
"
In carrying out our invention we construct of any suitable metal, metals or
materials a hollow spherical lantern body A, provided with a suitable non-com-
bustible ventilating cowl or hood B, and a hinged door or opening C, preferably,
but not imperatively situated as shewn in the drawings. Regarding the cowl Bas
the top, and C as the back of A, we fix to and upon the front thereof, in the same
manner as that of projecting optical lanterns generally, an ordinary or any suitable
lantern lense D, having the usual condenser E, slide carrying aperture or slot F,
and focussing screw G, and the illuminant employed may be that of any suitable
type of oil lamp, placed in A, or if convenient, that of an ordinary oxyhydrogen
burner, or if the current be available, that of an electric arc or incandescent lamp,
but for general or business purposes we may find it more convenient to use an
ordinary gas burner for this purpose, and this method of illuminating A we have
shown in Fig. 3, in which is fixed a standard jet H, receiving its supply of gas
from the nearest available point, which may be arranged to enter at the bottom
of H from the outside of A as shewn, or a pipe may be arranged inside A con-
nected to the side of H if preferred, the burner being on a level or thereabouts
with the lense D.. The door or opening C may be provided with a metallic or
glass reflecting mirror J, and ventilating holes K if needed.
The advertisement to be reflected would be painted or otherwise provided upon
a glass or other transparent substance, similar to that of a projecting lantern slide,
and this when placed in F would be projected horizontally by the lense D, but
the object of our invention is that the said advertisement may be reflected in any
direction, and at any angle relatively to the apparatus, and we attain this by
placing upon the outer or free end of D, a metallic or other collar M, to which
is hinged an adjustable mirror L. The collar M fits sufficiently loose upon D
that this may be rotated thercon at will, carrying with it the mirror L, and
arrested at any point of its rotation and thereat fixed by the means of a set
screw N or any suitable equivalent therefor.
Given that N is so fixed that the hinge of L is horizontal, if L be now placed
at an angle of 45° relatively to N, the advertisement upon the slide in F, would
be reflected into L, and thereby deflected in a downward vertical direction as
shewn by the arrow in Fig. 1, or if L be at an angle of 60°, in the direction
shewn by the arrow in Fig. 3 and so on. It will therefore be understood that
the angle of reflection is regulated by the adjustment of L, but the direction of
such reflection (which may be upward, downwards or horizontally in either
direction) is attained by the adjustment of the collar M.
Upon the outer surface of A, preferably at right angles to, and in line with the
lense D, we provide two projecting studs O and O¹, in order that the apparatus
may be thereby pivotted upon suitable brackets, and these in turn may be fixed
vertically or horizontally in any position desired, and by the means of suitable
set screws or the like engaging with the said brackets and the studs O O' the
apparatus may be set at any angle from the horizontal desired.
By these means the apparatus may be fixed in almost any position, and at any
height desired, and the advertisement reflected in any direction upon any flat
surface at a suitable distance therefrom, and in some cases the apparatus.may be
so placed that the source of the said reflection would to some extent be hidden
from the observer, whose curiosity being aroused, would materially add to the
effect of the advertisement, which would be still more effective if the advertisement
slides were periodically changed.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed we declare that what we

of spherical or spheroidal form, provided with projecting studs O, O', for pivotally
suspending the same upon suitable brackets, and having a ventilating cowl or
hood B, door C, with or without a reflector J, a projecting lense D, with con-
denser E, and slide aperture F and provided with an adjustable collar M, carrying
an adjustable mirror L, the whole connected, combined and operating substantially
as, and for the purposes herein described and shewn by the appended drawings.
