Improvements in Reflectors and Ventilators for Lamps and Burners.
JACQUES GUIRAUD of 9 Passage des Eaux, Passy near Paris, France, Inventor
do hereby declare the nature of this invention to be as follows:-
The object of my invention is a reflector for lamps and burners of all kinds.
The reflector is composed of wings and rotates in a vertical plane. It is actuated
by a screw, moved by the expanded air, and turning in a horizontal plane above
the flame of the lamp.
Three metal rods connected at their extremities by copper fittings made to fit
exactly to the glass chimney, form a support for the reflector and for the actuating
screw. A small transverse rod fixed to the vertical rods by a screw, serves as a
rotary axis for the reflector. All this device is fixed to the burner by screws and
may be applied to any system of lighting.
The actuating screw, being set in motion by the expanded air, moves the reflector
by touching the ends of the wings.
My screw-reflector offers numerous advantages; it works without disorder for
an unlimited length of time and never costs anything for maintaining it. It is
applicable to any system of lighting. Moreover the screw forming a ventilator
rarefies and purifies the pair.

1. JACQUES GUIRAUD of 9 Passage des Eaux, Passy near Paris, France, Inventor
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:-
The object of the present invention is a screw-shaped reflector for lamps and all
kinds of burners.
This apparatus offers many advantages; it cannot be worn out and causes no
expense of maintenance; it may be applied to every system of lighting; moreover
the screw forming ventilator rarefies and renders the air wholesome.
In the annexed drawings Fig. 1 is a view in elevation of my screw-shaped
reflector, Fig. 2 shows a modification of the same and Fig. 3 shows the metallic
circle clasping the lamp-glass.

page_text: This reflector is composed of several blades A, made of aluminium or other metal,
similar to those of ventilators and fixed at their base upon a disc B.
This disc B pivots in a vertical plan upon a horizontal axle b fixed to the vertical
rod F by means of a screw V1. This' rod along with the rods C and H' are con-
nected at their extremities by copper fittings L and T made to fit exactly to the
glass-chimney, and form a support for the reflector (by means of the axle b) and for
the actuating screw.
The rod is surmounted by a little axle K on which turns the actuating
screw E composed of three or four blades e and moved by the expanding air leaving
the chimney.
The extremities of the blades e impart a rotary movement to the reflector by
means of the lugs M secured to the blades A and which engage with said blades e.
The fitting L is fixed to the chimney by means of screws V.
The modification shown in Fig. 2 and which I prefer does away with the
actuating screw. This latter is replaced by a spiral spring C as in all horologic
movements. The disc B turns upon a small horizontal stem D, which serve as its
rotatory axis and is fixed by a screw V¹ upon a metallic vertical rod F G, whose
lower part is applied by means of a screw V to a metallic circle Hclasping the lower
part of the lamp-glass I or the gas-burner to which it is fixed by 3 tightening
screws X.
The apparatus has a quick rotatory movement through the spring C which is
wound up in the same way as with clock-work movement.
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 :-
1. A reflector, distinguished by a screw with blades A; arranged vertically behind
the flame and an operating screw E, moved by the expanded air and setting the
blades of the reflector in motion.
2. A screw-shaped reflector in aluminium or any other metal acting at the
same time as ventilator, put into movement by a spiral spring which. is wound
up, and applicable to all kinds of lighting apparatus.
