Improvements in Lamp Reflectors or Shades and the like.
We, GILBERT WOOLLARD HATTERSLEY of 6 Trinity Street Cambridge in the County
of Cambridge China and Glass Dealer and ROBERT EDWARD AYERS of 6 Holland.
Street New Chesterton Cambridge in the County of Cambridge House Decorator do
hereby declare the nature of this invention to be as follows :-
Our invention has reference to oil lamp gas candle and other reflectors or shades
which are so constructed as to be capable of adjustment in any direction.
The reflector or shade may be of ordinary form or construction but we prefer to
make it of the shape of a segment part of a cone frustrum so as to be capable of
being placed in a position for shading the eyes and throwing the light onto the
spot desired without darkening a greater part of the room or other space. The
reflector is jointed to a vertical or other bar or rod of round or other section in
such manner as to be adjustable as regards height and angle and this bar is fixed
to or made in one with a foot of any convenient form and weight. Or the vertical
rod may be clamped on to the lamp or other convenient object. According to one
modification we make the foot in the form of a semicircle or a horseshoe so as to
allow of placing the lamp, candle or gas standard close to the vertical rod. The
reflector may be clamped onto the vertical rod at any desired height from the ground
or table. Instead of making the reflector adjustable as regards height on the vertical
rod the latter may be made telescopic so as to slido up and down with one or more
telescopic joints or we may employ a rack and pinion motion or any other convenient
arrangements for raising lowering and swivelling either in a vertical lateral or any
other intermediate direction or directions.

COMPLETE SPECIFICATION.
Improvements in Lamp Reflectors or Shades and the like.
We, GILBERT WOOLLARD HATTERSLEY of 6 Trinity Street, Cambridge, in the
County of Cambridge, China and Glass Dealer and ROBERT EDWARD AYERS of
6 Holland Street, New Chesterton, Cambridge, in the County of Cambridge, House
Decorator, 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 :-
Our invention has reference to oil lamp, gas, candle, and other reflectors or shades,
which are so constructed as to be capable of adjustment in any direction.
The reflector or shade may be of ordinary form or construction but we prefer
to make it, as will be seen by referring to the accompanying drawings, of which
Figure 1 is an elevation, and Figure 2 a plan of one form of reflector with its stand'
constructed according to our invention; it will be seen that the reflector A is made,
as we prefer to make it, in the shape of a segment part of a cone frustrum, in such
manner as to be capable of being placed in a position for shading the eyes and throwing
the light on to the spot desired without darkening the greater part of the room or
other space. The reflector A is jointed to a vertical bar, pillar, or rod B in such
manner as to be adjustable as regards height and angle. This is attained by means
of a hinged, joint a which is provided with a small thumb screw a¹ for the purpose of

page_text: locking the joint a and thereby the reflector A at any desired angle in the vertical
plane. The joint a is preferably made in one with a sliding socket b which is movable
up and down and round the vertical standard rod or pillar B but capable of being
fixed thereon at any place by means of the set screw 6'. The rod B is here shewn
fixed to or made in one with a circular foot C of convenient form and weight. The
part e is provided as a handle to enable a firm and convenient hold to be taken when
moving the reflector about, and the top of rod B is provided with a ring 2 for the
same purpose. The rod B might however be provided with any well known clamping
device, for application to special purposes, such as to the pedestal of a lamp or other
convenient object, as circumstances dictate.
Instead of making the reflector A adjustable as regards height on the vertical rod
or pillar B, the latter may, as shewn in Figure 3, be made telescopic so as to slide up
and down with telescopic joints B B1 and B2. Suitable stops are employed herewith
in order to prevent the several joints from coming apart when they are drawn out
to their full extent. Or a rack and pinion motion may be employed or any other
convenient arrangements for raising, lowering, and swivelling, either in a vertical,
lateral, or any other intermediate direction or directions.
Figure 4 is a detail view shewing a simple mode or device for obviating the
necessity of the thumb-screws and it may also be applied to the telescopic joints for
holding a movable part in any desired position, and rigidly enough for all practical
purposes. It consists of a spring 6' which is screwed, rivetted, or otherwise fixed to
one of the parts and is bent down and presses on the other part a with sufficient
force to hold the two together in any desired position. It is however evident that any
other suitable locking or friction device may be applied equally well.
According to another modification, as shewn in Figures 5 and 6, which are
respectively elevation and plan, we make the foot C in the form of a semicircle or a
horse shoe, so as to allow of placing the lamp, candle, or gas standard close to the
vertical rod B.
Figures 7 and 8 are elevation and plan respectively of a reflector stand in which
the lamp, candle, or the like is put into the centre of the foot C thereby economizing
space and facilitating the carrying about of the lamp without separating it from the
reflector; the handle c being further strengthened by a rail c¹ which also serves to
prevent the lamp from being inadvertently knocked over.
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 the what we
claim is
First. In combination with a pillar a movable socket or its equivalent having a
swivelling fitting for attachment to a reflector or shade for a lamp or the like for
adapting the said reflector to be adjusted and held in any required position.
Second. A reflector A for lamps or the like consisting of a segment part of a
frustrum of a cone substantially as described and shown.
Third. A reflector for use with lamps or the like consisting of the reflector part A
hinged joints a, and socket b, in combination with a vertical rod B, provided with a
foot c, substantially as described and shown.
Fourth. A reflector for use with lamps or the like consisting of the reflector part A
and hinged joints a, in combination with the telescopic rod B, B1, B2, provided with
foot C, substantially as described and shown.
Fifth. The constructions of reflectors as shown on the accompanying drawing.
