COMPLETE SPECIFICATION.
A Revoluble Guide Beam for Broadside Subaquatic Torpedo
Launching Tubes.
I, EMIL KASELOWSKY, of 17/18, Chaussee Strasse, Berlin, N., in the German
Empire, Counsellor of Commerce, 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 a guide beam for subaquatic broad side tubes,
which is adapted to be turned out from board of vessel and allows the launching
tubes hitherto employed for subaquatic bow armours to be also used for broad-side
torpedos. Owing to the improved construction of guide beam "ordinary full
tubes," partial-or entire box pieces, may be used corresponding to the space at
disposal within the vessel with the application of the sluice slides heretofore
employed or of any other convenient closing agent. Moreover this construction of
the guide beam is conducive to effecting the greatest possible economy in
space for
the appurtenant launching tube, as all such complicated mechanisms are dispensed
with which must necessarily be in connection with the launching tubes proper for
moving out such guide beams which are arranged to be shifted out.
In order to make my invention more clear, I refer to the accompanying sheets
of drawing, in which similar letters denote similar parts throughout the different
views and in which :
Fig. 1 illustrates the guide beam in its inoperative position, it being generally of
a trilateral prismatic cross section and laid into the side of the vessel where it is
lodged in a wood block as shown in cross section by Fig. 3. is the guide
beam which is provided with a T shaped guide slot . In the latter the torpedo
is guided by means of a correspondingly shaped guide bar or projection. The
beam itself is broken through in order to afford the torpedo a uniform descent
when released, and it is furthermore revoluble about pivot d and has at the top an
clongation which serves as a closing for the launching tube 7.
Fig. 1 is a cross-section through the launching tube.
Fig. 2 shows the guide beam in the fighting position, it being turned outward by
means of draw rod g, while the extension & lodges itself in a cut of the launching
tube so as to render the latter completely free.
Fig. 2 shows a cross-section through the launching tube, while
Fig. 3 represents a cross-section through the guide-beam when lodged in the side
of the vessel.
Fig. 4 illustrates the operating mut or spindle by means of which the beam is
brought from the inoperative position into the fighting position.
Fig. 5 is a front view of a portion of the guide beam.
Fig. 6 a cross-section of the beam on an enlarged scale.
Fig. 7 illustrates the fork serving for connecting the pushing barg with the guide
beam.
Fig. 8 represents the turning hinge of the guide beam with packed extractible
turning pivot d.
The guide beam is operated as follows:
The guide beam revoluble about pivot d can be brought from its position of
rest shown in Fig. 1 into the fighting position Fig. 2 by means of the spindle p.
On the latter moves forward the nut m having its guiding in box k Fig. 4. Rod g
revoluble about pivot g² and secured with its other extremity to the guide beam,
turns the beam outward and the elongation blodges itself in the cut of the
launching-tube, so that the T-shaped groove provided in the guide beam forms a
continuation of the T-shaped groove fitted in the launching tube. In this

page_text: manner the torpedo receives overboard guiding, when being launched and is held
in its position by the guide beam when leaving the broad side of the vessel, until
the tail end of the torpedo is free of the broad side; at the same time the torpedo
is released from the guide-beam.
It must be pointed out as particularly important, that the turning pivot d, as
shown by Fig. 8, is so lodged, as to be extractible and packed by a stuffing box,
thus forming a device by means of which it is possible, to casily disconnect the
guide beam (from within the vessel) from the launching tube by drawing out the
pivot, in case the guide beam gets out of order and cannot be returned into its
inoperative position. In such a contingency merely the fastening bolt of the fork g',
after the pivot dhas-been drawn-out, need be removed by a diver, said bolt being
for this purpose provided with an appropriate fastening means (in this case a
wedge).
$
The improved arrangement, affords a material advantage over the heretoforc
usual constructions with a bearing beam adapted to be shifted out, with which con-
structions it is impossible to withdraw such beam in case of accidents. Under these
circumstances it is furthermore matter of great difficulty to remove the beam from
the launching tube. A vessel thus in without the beam withdrawn or removed
from the launching tube would not be able to pass through the sluice gates of a
dock.
$
It is evident, that the draw rody takes up the whole pressure exerted by the
passing water on the beam. The latter receives by the support near its outer end
a far greater resistant capacity, than the hitherto used guide beain disposed to be
shifted out, which lacks any support outside the vessel.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1.) In broad side subaquatic torpedo launching apparatus, the combination of
the guide beam b revoluble with regard to the vessel and leaning against, or being
lodged in, the side of the vessel, when in its inoperative position, while it is adapted
to be placed, from inside the vessel, by means of a pushing rod g into the fighting
position and to be maintained in such position for the purpose of allowing, during
travel of the vessel, torpedoes to be launched broadside under water under
protection of the beam, substantially as described.
2.) In broad side subaquatic torpedo launching apparatus with revoluble guide
beam, the combination with the guide beam, of an extension thereof, which serves
in its inoperative position simultaneously as closing for the side of the vessel and is
adapted in the fighting position to effect by the guide groove provided in-said
extension, the transmission of the torpedo guided in the launching tube, into a
guiding provided in the beam, substantially as specified.
}
3.) In broad side subaquatic launching apparatus with revoluble guide beam, the
combination, with the guide beam b, of a packed extractible turning pivot d for
the purpose of allowing the guide beam to be disconnected from the launching tube
from the interior of the vessel, substantially as specified.
