page_text: I EMIL KASELOWSKY of 17/18, Chaussee Strasse, Berlin in the Empire of Germany,
Engineer, do hereby declare the nature of the invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement:-
The accompanying drawing represents in side and end views a torpedo tube
shortened, together with the apparatus connected therewith for firing off the torpedo.
The first arrangement consists of two bolts h h, which may be arranged horizontally
or vertically. These bolts are capable of an in and out movement in such a manner
that they either (as drawn) project into the torpedo tube, or (on being drawn back)
come so far out from the tube, that the rearmost end of the torpedo can pass freely
forwards in the tube. When pushed inwards, these bolts h h serve to retain or hold
back the hinder part of the torpedo. Each bolt h carries at its end a lug, which forms
a stop for the sleeve of the bolt, and on which also a spiral spring so operates, that in
general the bolt h will be pressed in an inward direction. To the lugs of these bolts
are pivotted the arms kk, which are connected together by means of a link rod k¹ so
that the movement of the two retaining bolts always occurs at the same time.
a represents a cut-off valve, which shuts off the reservoir (filled with compressed
air), not shewn in the drawing, from the torpedo tube. b represents the connecting
pipe between the cut-off valve and reservoir. The valve is drawn in its closed position.
The rod g g' for operating the same is, at its rear end, fitted into a bracket piece which
is fastened on to the sleeve of one of the retaining bolts. This rod g₁g' is connected
with a hand lever by means of a pin or bolt. To the upper part of the hand lever l
a strong spring fis connected.
The upper end of this hand lever rests in a peculiarly shaped catch d¹ of the lever d
situated above it, from which, by the aid (in some cases) of a rod c, by hand power, or
by any other mechanical means, the entire firing-off mechanism will be set in motion;
thus the above named retaining catch will leave the hand lever / free, so that by the
tension of the spring f, the shut off valve will be lifted in the valve chest
a, and the
compressed air will be able to get to the rear of the torpedo in its tube by way of the
pipe b.
In the rod g¹ g', there is a slot at i.
lever of the lower retaining bolt, so
rises, and by this means the connected
drawn back out of the torpedo tube.
Against the rear edge of the same rests the
that when the rod g' moves forward, this lever
retaining bolts h h before referred to, will be

page_text: The forward end of the rod g¹ g¹ has no effect on the motion of the valve in the
valve chest a until the stop y on the rod g³ comes against the projecting part y¹ of the
valve rod. During the traverse from y to y', the retaining bolts hh will be drawn out
of the torpedo tube, so that they leave the torpedo perfectly free, before, in the course
of the further movement, the valve for stopping the admission of air is opened.
The forward end of the torpedo tube is closed toward the outside by means of a
cover p. This cover must of course be removed before the torpedo is projected from
its tube.
In order to prevent any mistake in the sequence of the operations in working the
tube, the apparatus is so arranged that the firing-off apparatus before described,
cannot be set in action until the cover p is completely removed. To this end, the
firing-off apparatus is so combined with the operating mechanism of the cover p,
by means of a connecting rod m, that the lever 1, and thereby the entire firing-off
apparatus, will not be able to move while the tube remains covered, because the end
of the rod m abuts against a slide n, or other sliding mechanism, so that the
advance of the rod m is at first prevented, and not until this slide n has been pushed
up by the removal of the cover p, will the movement of the rod m, and with it that
of the entire firing mechanism, be free.
The intermediate mechanism between the cover p and the stop guide n may vary
´according to circumstances. In the drawing is shown, by way of example, a shaft s
capable of being turned by means of a handle q, the said shaft carrying at its
end the cover p. By means of the lever u on this shaft s, and the intermediate
mechanism vvv, the retaining action of the slide n upon the rest of the mechanism,
by the movement of the cover p, is effected. In the sliden, a hole w is bored. A
hole of the same diameter is also bored in the guide piece x, in which the slide is fitted.
In the drawn position, the end of the rod m abuts against the slide n. So soon as the
cover P is removed, and the guide n is thereby drawn back, the hole w of the slide n
comes opposite to the hole of the guide piece x, so that the rod m has now a clear
passage made for it through the hole in the slide and through that in the guide piece m.
So soon, therefore, as the rod c is pulled, the whole firing-off mechanism will be set in
action.
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. The arrangement of two vertical or horizontal retaining bolts h h, which are so
connected with the firing-off apparatus (or with the air admission valve a), that on
the movement of the opening lever 1, the retaining bolts will be first drawn back
before the opening of the cover; and that then, when the cover is opened, these
retaining bolts will be held fast in their drawn out position. In the closed position of
the cover, these bolts can however be drawn back by hand.
2. The combination of an opening lever d (capable of being operated from any
desired portion of a ship or vessel) with an arrangement of tension spring, in such a
way, that by the release of a latch or bolt d¹, this discharging apparatus can be
automatically set in action by means, for instance, of a tension spring for other
suitable mechanism.
3. The "locking" of the front closing cover p (either in the form of a clack
valve or of a slide valve) in torpedo tubes, by the discharge apparatus, in such a way,
that by means of a slide n, or any other form of bolt mechanism, the movement of the
entire arrangement of discharge levers g' &c., will be prevented (in other words, the
opening of the discharge valve a will be rendered impossible), until the front closing
valve or cover is completely opened and the torpedo can freely leave the tube.
