JEAN PAUL DUOASSOU, OF PARIS, FRANCE.
SCREW-PROPELLER.
SPECIFICATION forming part of Letters Patent No. 675,722, dated June 4, 1901.
Application filed May 19, 1900.
pellers for ships or boats,- andhas for its object to render the propeller readily adjustable as to position in accordance with thedi rection it is desiredto impart to the vessel.
In order that my invention maybeclearly understood and readily carried into effect, I will describe the same fu'lly'with reference to the accompanying drawings, in which; i I Figures 1 and 1 representa vertical section of my improved propeller'arrangement 'se-- cured to the stern ofja boat of b any descrip tion, and Fig. 2 is a horizontal section online XYofFigll To render my improtedpropeller ble for all cases and to be manipulated b'yun skilled persons, I have arrangedit so th'at'it' can be fixed to anyboat in'i'a comparatively short'time, I jf M In order toavoid complication in the'mech; anism for-reversinglthe direction of travel'of the vessel,which in existing arrangements can' only be effected by first stopping the motor or by a special and cumbersome mechanism. which is necessarily heavy and complicated, I have devised the-following propeller arrangeinent, which is of great simplicity and permits of turning aronnd i tone place, of going ahead or astern, and generally in any direction without being ob1iged to stop 019130 31- ter the speed of the-motor or of the propeller, and this by the simple rotationof the box car-- rying the propeller; 1'
The apparatus'comprises the boxeso and '11,;
I connected together by a tube a, the box b, carryin g the propeller, bein 'gv-capable of performinga rotary inotioniaround the tube cqwhen operated by a gear-wheel d,;firmly secured to, :the box andgearing with apinion c, operated from the boat in any-suitable manner. The shaft 9 of the motor 0, carries bevel pinion h,
gearing with a pinion i, keyed to theshaft j,
which latter carries apinion 70, adapted to serial No. 17,273. (No model.)
gear with a pinion Z, thus rotating the shaft 'm' and propeller n. It will be obvious that the transmission of the movement from the motor to the propeller is not in any way im= peded by the rotary motion of the box I).
Upon the tube 0 is fixed a bracket 19, secured by screws to the keel or stern post of the boat for the purpose of holding the arrangement in position, while in combination therewith the motor 0 is fixed upon the rear seat at the stern of the boat.
The operation of my improved device is as follows: Upon the rotation of the shafting f .thepropeller is caused to occupy any one of the'iprincipal positions 1 2 3 4 (shown in Fig; 2) orany intermediate position, as may be desired, The position 1 causes the boat to travel ahead, position 2 causes the boat to turn to the right, position 3 causes the boat ;.totravel astern, and position 4 causes it to turn to the left.
If it is desired to stop the vessel while allowing the propeller to rotate, it suffices to revolve the box bin a continuous manner either in one direction or the other;
The shaftfmay-be driven by flexible shaftin g g or by ordinary shafting through the intervention'of a fly-wheel rotated in any ap- *propriate manner from the boat, and which forthe purpose of effecting the rotation of the box b may be driven by means of a hand ;.wheel s and strap t, the said hand-wheel being also capable of being used for starting when using a petroleum-motor.
What I claim is- 1. In a propeller for vessels, the combination with two boxes fixed to the stern of the vessel, the lower end being provided with a gear-wheel, and a tube connecting said boxes,
of suitable shafting journaled in said boxes and tube, a screw-propeller operated by the shafting, a' pinion meshing with said-gearwheel, and a suitably-operated flexible shaft for turning said pin-ion, whereby the box carrying' the propeller-shaft is tially as set forth.
t 2. In a propeller for vessels, the icombina i tion. with'two boxes fixed to the stern of the loo vessel, the lower box, being provided atthe top with'a gearwheel, and'atube connecting the said boxes, of suitable shafting journaled in said boxes, a screw-propelleroperated by? v the shafting, a pinion meshing with said gearspecification in the presence of two subscrib wheel, a suitably-operated bent flexible shaft ing witnesses. for turning said pinion, and means for connecting the said shafting and the flexible JEAN PAUL D UCASSOU' 5 shaft, whereby the box carrying the propel- Witnesses:
ler-shaft is rotated, substantially as set forth. EMILE LEDRAL,
In testimony whereof I have signed this EDWARD P. MACLEAN.
