Smoke and Fumes Collector Appliances for use in Instantaneous
Photography.
I, AUGUST WEISS, of 3 Meisengasse, Strassburg, Alsace, Germany, Photographer,
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 this invention is an automatically-working apparatus for collecting
and enclosing the smoke and fumes generated through the igniting of the powder
employed in the taking of instantaneous photographs. The essential feature of
the invention is the arranging of a bag above the instantaneous light apparatus,
this bag being in a collapsed state before the igniting of the flash powder, and
leaving the lamp for the instantaneous lighting free, but after the ignition of
the powder it unfolds automatically by means of the flame, and then encloses
the instantaneous light apparatus, together with the smoke resulting from the
ignition.
Figures 1 and 2 show a form of the apparatus and its connection with a lamp for
instantaneous light, Figure 1 elevation illustrating the position of the apparatus
before the igniting of the flash powder, and Figure 2 its position when actually
effective, after the ignition, whilst
Figure 3 is a plan view of a detail.
Figures 4 and 5 are sections of a slightly modified form of the apparatus.
The flash powder 1 to be ignited lies on a table 2 which is fixed on a stand 3, 4.
It is ignited, for example, by the forward motion of a carrier 5 with a match 6,
the match being rubbed on a friction surface, which is not shown, and entering the
body of the powder through an opening in the back 7 of the table. The powder
may, however, be ignited in any other manner.
To the rod 3 of the stand, an arm 8 is fixed. This arm carries the smoke bag
which is open below and closed above. The bag like part 9 is placed over a
frame 10 (plan view Figure 3), and has sewn into it a ring 11.
To the arm 8,
In
levers 12, 13, are pivoted, these levers when in their horizontal position, support
and bear the bag 9 in the collapsed or folded state (Figure 1). To the shorter
ends of the levers, cords 14, 15, are fastened, which are kept stretched and carried
through the flash powder, or in other words, through the area of the flame.
Figure 1, the cords 14, 15, are carried through an opening in the back 7 of the
table, then through the body of powder 1, or in other words, through the area
of the flame, and are kept stretched in any suitable manner, for example, by being
wound around the guiding sleeve 16 of the carrier 5. In this condition, the smoke
collector apparatus is ready for use.
If the flash powder be now ignited, and at the same moment, the photograph be
taken, the flame produced burns through the cords 14, 15, so that the levers 12, 13,
lose their hold, and the bag which is loaded or charged with the ring, sliding down
from the levers, unfolds. Thereby, the lamp for the instantaneous light, and the
ascending smoke, will be entirely surrounded, and the latter completely intercepted,
this latter operation being further effected by pulling the cord 17 which serves for
contracting the bottom of the bag.

page_text: Figure 2 shows the apparatus in this position, in which the levers 12, 13, assume
a vertical position by their own weight after the cords are burned through.
In order to make the apparatus again ready for use, the separated cords are
united again, or new cords-fastened to the levers 12; 13.
The arm 8 is arranged suitably adjustable on the rod 3 of the stand.
The frame 10 is arranged on a pin 18, in the upper end of the arm 8, by means
of a central socket. Having regard to the fact that the table 2 is of a suitable
lengthy (or oblong) form, it is advisable to make the frame elliptical and the bag
of corresponding shape.
Figures 4 and 5 illustrate, in section, a simplified form of the invention, from
which the levers 12, 13, are, absent..
The cords 14, 15, are, in this case, fastened to hooks 19, 20, rove through eyes
or loops 21, 22, 23, 28, 29, 30, in the bag, and eyes or loops 24, 25, 26, 27 on the
cross-stay of the frame, and further, on.as arranged.in. Figure 1. Figure 4:shows
the bag 9 in the folded state, the lower part 91 hanging, down free. When the
cords 14, 15,,are burned through, the bag unfolds through. the dropping: of the
ring 11, Figure 5, whereupon the lower part 91 is closed by pulling the cord 17.
Having now particularly described and ascertained the nature of, this. inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-.
1. A smoke and fumes collecting contrivance for instantaneous light apparatus,
characterised by a bag arranged above the said' apparatus and held in a collapsed`
condition; and which bag automatically unfolds by the action of the flame arising,
from the powder furnishing the instantaneous light; and in doing so, to surround"
the instantaneous light apparatus and enclose the smoke, as set forth.
2. A form of the smoke collecting contrivance as in Claim 1, the characteristic
feature of which is that an arm (8) arranged on the instantaneous light apparatus,,
or in other words, on a stand belonging thereto, carries on its upper end, a
frame (10), on which a bag (9) is fixed; whilst levers (12, 13) pivoted on the arm (8)
are so held by means of cords (14, 15) which are carried through the body of 'the
flash powder, or in other words, through the area of the flame, that they serve
as supports for the collapsed bag, so that upon the flash powder being consumed,.
the cords are burnt or destroyed; and the bag deprived of' its support beneath,.
unfolds; enclosing the smoke and fumes; and also the instantaneous lighting,
apparatus.(Figures 1; 2)..
3.1. A modification of the smoke collecting contrivance as in Claim 2, from which
the levers (12, 13,) are omitted, and the cords (14, 15) are fastened direct to, the
bag (9) or to a ring (11) belonging to such bag, and guided (or carried) in a-
suitable manner, for example, through eyes or loops on the frame (10).
4. A form of the smoke and fumes collecting contrivance according to. Claims 1;.
or 2, 3, the characteristic feature being that the bag can be drawn in at the bottom
by means of ia cord or string (17).
