(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, RODOLPHE HELBRONNER, Congreve and Chemical Light Manu-
facturer, of No. 3, Spring Terrace, Vauxhall Walk, in the Parish of
St. Mary, Lambeth, Surrey, do hereby declare the nature of the said
Invention for "A CHEMICAL LIGHT, AND APPARATUS FOR MANUFACTURING
THE SAME," by my new mechanical process, to be as follows:—
Fig. A, shows several wheels with hinged spindles. Fig. B, is an
interior view of the spindle, and a side exterior view, with a sliding ring,
each spindle being lined with flannel, and having a longitudinal, and on
one end a egged shaped groove in the centre, Fig. B. Fig. C, shows
two boards or plates in which the wheels are introduced in a transversed
section, raised above the table about 6 inches, to which they are secured,
and adjusted into a wooden frame, to slide by means of springs or other-
wise, see Fig. K. Fig. D, shows a front of a wooden board, nine inches
by thirty inches, having a longitudinal groove near the edge of the

page_text: board about of an inche wide, see Fig. E, in which is cut a number of
small holes, egg-shaped, at short distances, having a groove to cach, see
Fig. F, to receive the splints or wires from the spindles. Fig. G, shows
a bar fitting the longitudinal groove, with teeth about of an inch
thickness, of wood or metal, hinged at the right-hand side of Fig. D,
movable into Fig. E. Fig. H, shows a large wheel, nine to 12 inches
in diameter, of wood or metal, to bring in motion the little wheels, as
Fig. A.
Having thus described the nature of the apparatus, I will now
describe the manner of performing the same.
I secure to the table Fig. A, opposite Fig. D, for the purpose of
bringing in contact the spindles, Fig. B, with the grooves, Fig. F. I
then provide the longetudinal groove, Fig. E, with the fibrous sub-
stance, see No. 1; also Fig. B, the hinged spindles, with splints or
wires, see No. 2; and fasten the same with the sliding rings attached to
the spindles. In moving Fig. A, 1 of an inch space to the board,
Fig. D, the projecting splints or wires pass into the egg-shaped grooves,
Fig. F, upon the fibrous substance; and with the transversal bar, as
Fig. G, I close or cover with a slight pressure the longitudinal groove,
Fig. E, to hold the splints or wires, also the fibrous substance, in a
correct and even position; than I cut away or tare off the outside
fibrous substance close to the transveral bar, Fig. G. By five or more
retations I bring in motion with the wheel, Fig. H, the small wheels;
and the whole number of the projecting part of splints or wires will be
covered regularly with the fibrous substance to the precise shape of
Fig. E, in which they are turning, so to form No. 8. This second
operation being performed, I push the sliding rings backwards close to
Fig. C, throw or slide Fig. A, & H, backwards away from Fig. D,
lifting Fig. G, from Fig. E, and replace the same splints or wires as
shown, Fig. 3, reversed in the spindles, and perform again the same
operation as mentioned in No. 1, 2, 3, and I obtain No. 5. The
spindle-acting process being so far completed, I place No. 5, in the
usual congreve frames to dip them with cement and phosphorus pre-
parations.
By adopting the wooden board This n
T:

page_text: pendent of the spindles, I can manufacture the same article as
No. 3, & 5, by turning the splints or wires with fingers one after
the other.
I prefere well carded cotton woul to other fibrous substances, and
square splints to wires.
My Invention being thus fully described, I wish it to be understood
that what I claim as my Invention is,―
First, the above-desribed hinged spindle-machine and apparatus
with the longitudinal and transversal grooves for the purpose of cover-
ing the splints or wires with a fibrous substance or substances, and the
manner of performing the same.
Secondly, I claim the application of cotton wool or other fibrous
substance for the use of chemical light, as herein-before described.
