JOHN GARRETT TONGUE, of the Firm of Tongue and Birkbeck, Patent Agents
and Engineers, of 34, Southampton Buildings, Chancery Lane, in the County of
Middlesex. IMPROVEMENTS IN ARRANGING AND APPLYING PROPELLING APPARA-
TUS TO BOATS OR VESSELS FOR NAVIGATING RIVERS AND CANALS." A communi-
cation from abroad by Paul Jacquel, Engineer, Paris, France.
This Invention relates to improvements in the method of arranging and applying
propelling apparatus to navigation on canals or rivers, in order to avoid incon-
venience when the boat or vessel is empty or partly so.
The screw propeller or paddle wheel which gives motion to a boat or vessel when
immersed to the floating line will be out of water when the boat or vessel is empty
and floats, and is thereby incapable of acting to propel the vessel. For this purpose,
according to these improvements, in order to overcome this difficulty, the propelling
apparatus or motive power is placed and arranged in a chamber or casing which is only
attached to the boat or vessel by means of sliding bars, serving guides, and fixed, regu-
lated, and combined together by adjusting screws, when the two parts (one carrying
the propelling power and the other the boat or vessel) are both at their floating line.
The chamber or casing carrying the motive power serves as a special steam tug
or propelling apparatus to the boat or vessel to which it is fixed; and by this im-
proved application all difficulty in applying steam power for the propulsion of boats
or vessels on rivers or canals is overcome. Each boat or vessel will contain its
motive power and navigate either loaded or empty.
This improved motive power, contained in a special separate chamber or vessel,
can be detached from the boat or vessel during the time of loading, unloading, or

page_text: when at rest, and thereby, in case of need, can be applied to the propelling of one,
two, or more boats or vessels.
This improved vessel or chamber carrying the screw or other propeller is placed
according to the floating line prescribed by the regulations, according to the
different canals or rivers it is to navigate, the boat or vessel working freely on
sliding bars will gradually sink when being loaded, until it reaches the depth
required to be fixed and secured to. the propelling chamber by means of adjusting
screws. The same facility is afforded both in loading and in unloading the vessel,
but in a reverse manner.
It is only necessary to unloosen the adjusting screws when the boat or vessel
arrives at its destination to be unloaded. The boat will then rise gradually as she
is being unloaded until she is entirely empty, and by tightening the adjusting
screws the boat or vessel is ready to start again.
In order that the guiding bars may work easy, mechanical means may be
employed.
These improvements are applicable to any screw propeller submerged to a suit-
able depth for propelling the boat or vessel attached thereto at whatever depth she
may be immersed.
And in order that this Invention may be clearly understood, I will proceed to
describe the Drawings hereto annexed,-
Figure 1 shows a horizontal view of a boat or vessel loaded, the same being at a
level with the chamber or casing containing the motive power. Figure 2 shows a
plan of the same, partly in section. Figure 3 shows a longitudinal view of the same
boat or vessel when empty, the chamber or compartment containing the motive
power being sunk in order that the screw may be submerged.
In all these Figures the same letters refer to the same corresponding parts.
a is the hull or compartment of the boat or vessel for receiving and carrying
merchandise or freight of any kind; b, store for the rigging; c, compartment in
which is fixed the boiler d and the engine e, giving notion to the screw propeller f;
g, channels or tubes to convey the water to the screw propeller; h, rudder; i, verti-
cal uprights fixed to the compartment a; j, tubes surrounding the uprights i;
k, driving wheel put in motion by the screws ; these screws are actuated by a
hand wheel m, or by any other suitable mechanical means. The driving wheel k
and the screws act to raise or lower the compartment c, when the compartiment a
is either loaded or unloaded; n, adjusting screw to fix or adjust the compartments
a and c; o, floating line, as seen in Figures 1 and 3; the screw propeller, notwith-
standing the boat or vessel being loaded or empty, will always be submerged.
Practically, the means employed to fix or attach the screw or other propelling
apparatus to the boat or vessel may be varied considerably, and may consist simply
of cables or ropes.
The screw propeller by means of its independent construction with regard to the
boat or vessel may be fixed to any kind of boat either of iron or wood and of any
kind of form or dimensions.

JOHN GARRETT TONGUE, of the Firm of Tongue and Birkbeck, Patent Agents
and Engineers, of 34, Southampton Buildings, Chancery Lane, in the County of
Middlesex. IMPROVEMENTS IN ARRANGING AND APPLYING PROPELLING APPARATUS

from abroad by Paul Jacquel, Engineer, of Paris, France.
This Invention relates to improvements in the method of arranging and applying

page_text: propelling apparatus to navigation on canals or rivers, in order to avoid incon-
venience when the boat or vessel is empty or partly so.
The screw propeller or paddle wheel which gives motion to a boat or vessel when
immersed to the floating line will be out of water when the boat or vessel is empty
and floats, and is thereby incapable of acting to propel the vessel. For this purpose
according to these improvements, in order to overcome this difficulty, the propelling
apparatus or motive power is placed and arranged in a chamber or casing which is
only attached to the boat or vessel by means of sliding bars serving as guides, and
fixed, regulated, and combined together by adjusted screws, when the two parts (one
carrying the propelling power and the other the boat or vessel) are both at their
floating line.
The chamber or casing carrying the motive power serves as a special steam tug
or propelling apparatus to the boat or vessel to which it is attached, and by this
improved application all difficulty in applying steam power for the propulsion of
boats or vessels on rivers or canals is overcome. Each boat or vessel will contain
its motive power and navigate either loaded or empty.
This improved motive power, contained in a special separate chamber or vessel,
can be detached from the boat or vessel during the time of loading, unloading, or
when at rest, and thereby, in case of need, can be applied to the propelling of one,
two, or more boats or vessels.
•
This improved vessel or chamber carrying the screw or other propeller is placed
according to the floating line prescribed by the regulations, according to the
different canals or rivers it is to navigate, the boat or vessel working freely on sliding
bars will gradually sink when being loaded, until it reaches the depth required to
be fixed and secured to the propelling chamber by means of adjusting screws.
same facility is afforded both in loading and in unloading the vessel, but in a
reverse manner.
The
It only necessary to unloosen the adjusting screws when the boat or vessel
arrives at its destination to be unloaded. The boat will then rise gradually as she
is being unloaded until she is entirely empty, and by tightening the adjusting
screws the boat or vessel is ready to start again.
In order that the guiding bars may work easy, mechanical means may be employed.
These improvements are applicable to any screw propeller submerged to a suit-
able depth for propelling the boat or vessel attached thereto, at whatever depth she
may be iminersed.
And in order that this Invention may be clearly understood, I will proceed to
describe the Drawings hereto annexed.
Figure 1 shows a horizontal view of a boat or vessel loaded, the same being at a
level with the chamber or casing containing the motive power. Figure 2 shows a
plan of the saine, partly in section. Figure 3 shows a longitudinal view of the
same boat or vessel when empty, the chamber or compartment containing the
motive power being sunk in order that the screw may be submerged.
In all these Figures the same letters refer to the same corresponding parts.
a is the hull or compartment of the boat or vessel for receiving and carrying
merchandise or freight of any kind; b, store for the rigging; c, compartment in
which is fixed the boiler d and the engine e, giving motion to the screw propeller f;
g, channels or tubes to convey the water to the screw propeller; h, rudder; i, ver-
tical uprights fixed to the compartment a; j, tubes surrounding the uprights i;
k, driving wheel put in motion by the screws ; these screws are actuated by a
hand wheel m, or by any other suitable mechanical means. The driving wheel k
and the screws act to raise or lower the compartment c when the compartment a
is either loaded or unloaded; n, adjusting screw to fix or adjust the compartments a
and c; o, floating line, as seen in Figures 1 and 3; the screw propeller, notwith-
standing the boat or vessel being loaded or empty, will always be submerged.
Practically, the means employed to fix or attach the screw or other propelling
apparatus to the boat or vessel may be varied considerably, and may consist simply
of cables or ropes.

page_text: The screw propeller, by means of its independent arrangement with regard to the
boat or vessel, may be combined with any kind of boat, either of iron or wood, and
of any form or dimensions.
Having thus described the nature of the Invention and the manner of performing
or carrying the same into practice, what I claim under the above in part recited
Letters Patent is, the improved arrangement and construction of propelling appara-
tus, having the motive power placed and arranged in a special separate chamber or
casing, and attached to the boat or vessel by means of sliding bars serving as
guides, regulated and combined together by adjusting screws so as to enable the
separate chamber or casing containing the propelling apparatus with motive power
to slide vertically and be fixed to the boat or vessel at the floating line; also, in the
use and application of this improved motive power contained in a separate chamber
or vessel (when detached during the time of loading and unloading) for propelling
other boats or vessels, all arranged substantially in the manner herein-before
described and represented in the Drawings hereto annexed.
In witness whereof, I, the said John Garrett Tongue, have hereunto set my
hand and seal, this Fourteenth day of September, in the year of our Lord One
thousand eight hundred and seventy-seven.
