page_text: I, CHARLES JOSEPH GASTON PARCEINT, of 88, Rue des Marais, Paris, France,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to lamp-shades and has for object to increase or diminish
the extent or scope of these fittings so as to regulate according to desire the pro-
jection of the circle or disc of light.
In the following description I refer to the annexed drawings upon which ;-
Figure 1 is a diagrammatical elevation of a lamp-shade constructed in accord-
ance with my invention.
Figure 2 is a corresponding plan view.
Figures and shew respectively, modifications of the form of the invention
illustrated on Figures 1 and 2.
The lamp-shade shewn by the first two figures consists of a skeleton or frame-
work of wire similar to that of an umbrella and is operated in a very similar
manner; this framework, which is fitted with a covering of woven or textile
material or of paper, for restricting and projecting the light, consists of the
following parts:-
A, cap or crown serving as an ornament for the apparatus and allowing the
apparatus to be adjusted, when this is grasped by the hand.
a a a wire branches partly forming the skeleton of this crown.
bbb stays or connections for supporting these branches.
cupper movable ring serving as an axis for the joints of the branches kkk.

o slide or strap above referred to.
In the modification illustrated on Figures 3 and 4, are shewn springs P P P
which fix the lamp-shade in any of the various positions which it can assume;
this modification consists, as in the former arrangement, of a wire skeleton similar
to that of an umbrella and similarly opened and closed; this skeleton, which is
of course covered as in the first type described, comprises almost the same parts.
It will be sufficient to point out those which present some slight difference,
which are:~
B, a cylindrical cage, formed of the upper ring q and lower ring r, of the
cage A, and of uprights or rack-slides or rails sss; these uprights of any desired
number, connect the two rings and serve as racks or friction-plates for the
springs PPP. These springs serve to maintain the ring t fixed upon the
uprights 3 S 3. Upon this ring and by means of joints or pivots, the upper ends
of the branches or ribs kk kare fixed to the lower end of the springs PPP.
The rods iii connect these ribs to the lower ring which is itself connected to
the ring n by rods m m m.
The solid lines on the drawing represent the shade in its normal position,
whilst the dot and dash lines shew its most open position and the double-dot
and dash lines represent the narrowed or closed position.
To adjust the shade illustrated on Figures 1 and 2, the base of the cap A
is held by the hand, and is pressed down to extend or open the shade, and is
pushed upwards to close it. The same applies to the modification on Figures 3
and 4.
The shapes and dimensions and hinges or pivots of the shade and its parts may
be varied as desired and the parts of the whole may be constructed of any
suitable materials. The covering upon the ribs or arms may be plain or orna-
mented, transparent or opaque and of any suitable material whatever.

improvements in and relating to Lamp-shades.
I, CHARLES JOSEPH GASTON PARCEINT, of 88, Rue des Marais, Paris, France,
Merchant, 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:-
-
This invention relates to lamp-shades and has for object to increase or diminish
the extent or scope of these fittings so as to regulate, according to desire, the
projection of the circle or disc of light.
In the following description I refer to the drawings annexed to this specifica-
tion, and upon which:-
Figure 1 is a diagrammatical elevation of a lamp-shade constructed in accord-
ance with my invention. Figures 1 bis and 1 ter shew the shade in the closed
and full-open or horizontal positions respectively.
Figure 2 is a corresponding plan view.

page_text: Figures 3 and 4 show respectively a modification of the form of the invention
illustrated on Figures 1 and 2. Figures 3 bis and ter shew the modified form
illustrated in Figure 3 in the closed and full-open positions respectively.
Figure 5 is an enlarged detail view of part of Figure 1.
The lamp-shade shown by the first two figures consists of a skeleton or frame-
work of wire similar to that of an umbrella and is operated in a very similar
manner; this framework, which is fitted with a covering of woven or textile
material or of paper for restricting and projecting the lights, consists of the
following parts:-
-
A, which is a cap or crown serving as an ornament for the apparatus and allow-
ing the apparatus to be adjusted, when this is grasped by the hand.
a a a are wire branches partly forming the skeleton of this crown.
1 b b are stays or connections for supporting these branches.
is an upward movable ring serving as an axis for the joints of the
branches kk k
d is a lower ring fixed to the larger ring g by means of stay pieces ƒ ƒ ƒ, see
Figures 2 and 4.
e is a lower and inner ring fixed to the ring g by clasps h.
fff are stay pieces, of variable number, connecting the rings
and g.
9 represents a principal ring on which the arrangement is supported:
hhh are clasps, of a variable number, fixing the ring e to the principal
ring g
kkkare arms, ribs, or branches, also of a variable number, supporting the
principal shade or covering of the apparatus, and fixed by means of suitable
hinges or joints to the rings c and g.
I designate drawpieces or tie-rods of a variable number, connecting and
guiding, by means of their end joints, the branches kk to the ring 9 as before
stated, upon which they are pivoted.
m m m are rods or arms, of a variable number, connecting the rings e and n,
and supporting the whole device.
nis a ring which can be increased or lessened in diameter by means of a slide
or strap and intended to be fixed upon the lamp-burner, by means of clasps
or hooks, or to merely rest upon this latter.
o indicates a slide or strap above referred to.
In the modification illustrated on Figures 3 and 4 springs P P are shown
which fix the lamp-shade in any of the various positions which it can assume;
this modification consists, as in the former arrangement, of a wire skeleton
similar to that of an umbrella and similarly opened and closed; this skeleton,
which is of course covered as in the first type described, comprises almost the
same parts. It will be sufficient to point out those which present some slight
difference, which are:-
B is a cylindrical cage, formed of the upper ring and lower ring r, of the
cage A, and of uprights or rack-slides or rails sss; these uprights are of any
desired number and connect the rings serving as racks or friction-plates for
the springs PP P.
The rods connect the ribs & to the lower ring r which
is itself connected to the ring n by rods m m m.
Figures 1 and 3 of the annexed drawings represent the shade in its normal
position, whilst Figures 1 ter and 3 ter show its most open position and
Figures bis and 3 bis represent the narrowed or closed position.
To adjust the shade which is illustrated on Figures 1 and 2, the base of
the cap A is held by the hand, and is pressed down to extend or open the shade,
and is pushed upwards to close it. The same applies to the modification on
Figures 3 and 4. The material forming the cover folds or pleats itself between
the ribs when the shade is closed in, in manner similar to the cover of an
umbrella.
The shapes and dimensions and hinges or pivots of the shade and its parts
may be varied as desired, and the component portions of the whole may be

page_text: constructed of any suitable materials. The covering upon the ribs or arms may
be plain or ornamented, transparent or opaque, and of any suitable material
whatever. Paper, woven material or the like of any desired tint, may be em-
ployed for the shade proper. Similarly the framework may be coloured or covered
as may be found suitable, and, in the latter case, without interfering with the
freedom of the joints. The rings edge are preferably made of wire, to which
the wire arms and tie-rods are connected by means of loops.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
A lamp-shade comprising means for increasing or lessening, as may be desired,
the circle or disc of light, the said means being formed by mechanism substan-
tially as described with reference to Figures 1, 2 and or Figures 3 and 4
of the accompanying drawings.
