ART AND APPARATUS FOR IMPELLING AND MANEUVERING 0F FLOATING VE'SSELB Application filed November The aim of this invention is to provide a. simple and efiicient propelling device intended mainly to impel or maneuver such vessels as ocean, lake or river ships or boats and submarine types of vessels. These vessels may be any size or description.
, The salient feature of our invention is the device consisting or a whirling chamber in which the fluid or gas is admitted under pres- 0 sure tangential, or near tangential, to the walls of said chamber. The centrifugal force generated due to the method of entrance causes the influent to whirl along the walls travelling toward the nozzle where the energy 5 is dissipated in causing the fluid or gas to leave the chamber thru the nozzle in a spreading whirling cone extending beyond the nozzles edge, thereby reacting upon an area greatly in excess of the original entrance pipe 0 or the whirling chamber.
spreading motion produces a thrust on the medium surrounding the vessel, similar to that caused by a revolving propeller universally used by all mechanically driven vessels.
The resistance of a medium surrounding the vessel to the thrust, produced by several devices, will cause the vessel to move in the direction opposite to that of the thrust.
This invention in its preferred form of apparatus consists of a plurality ofdevices opening outside of the walls of the vessel below the surface of the water and having tangential, or about tangential. pipe inlets from a pressure chamber, which is in its turn connected to a pump or pumps. this pump or pumps, in turn, connected directly or indirectly to a prime mover. The inflow into the pressure chamber is maintained equal to the outflow thru the devicc,or devices,so that the predetermined pressure is always maintained by the pump. In cheaper and simpler installations the pressure chamber can be omitted.
At the present time the thrust on the medium surrounding the vessel is produced by propellers, or paddle wheels. which are revolved by prime movers thru complicated and cumbersome transmission mechanisms.which require the utmost care in design and in supporting it on the framework of the vessel. It induces enormous vibrations in the body This whirling 6, 1931. Serial No. 573,414.
It consists of no moving parts and does not possess the hazard of being disabled due to broken down propellers, caused by running aground or striking other vessels or objects. The device can even be utilized to pull or push the vessel oil a bar or other submerged obstruction upon which it might be grounded. There is no revolving shaft, protruding thru the hull, with its resultant tendency toward leakage. There are no gears, shafts, pulleys, chains or belts in transmitting power thru the hull, and the only moving parts are pumps, prime -movers and their connections. The vibrations set up by the common type of revolving shaft is eliminated. The installation for providing the necessary fluid or gas under pressure is of the simplest, thereby reducing the maintenance, initial cost and delays contingent on broken down equipment. The space occupied by its driving and transmitting mechanism is reduced to a minimum.
The accompanying drawings illustrate some of the many forms of the deviceand the general details of a typical installation. The invention will be better understood from the description of the drawings.

screwing, welding, casting or by any other practical method. As the fiuid enters chamber 2, it is whirled along its walls by centrifugal force until it reaches nozzle 4 where it leaves chamber 2 in a fanlike fashion. Nozzle 4 might be any shape that will give the maximum efficiency under the pressure used; it might be constricted in area or enlarged, or might even be varied in shape, in order to meet the particular conditions. Chamber 2 might be cylindrical, conical, spherical or any other shape that will prove serviceable. The length ofchamber 2 might .be any convenient length, and pipe, or pipes,
might enter chamber 2 at any distance from the back of the chamber.
Figs. 3 and 4 show another form of the device in which the fluid or gas under pressure enters chamber 2 thru more than one pipe tangent, or near tangent, to the walls of the chamber in plan and entering this chamber at an angle 3 varying from 0 to 18Q. Pipe 7 might be another entrance anywhere at the back of the chamber at an angle 8 varying from 0 to 90. One of the innumerable possible variations of the nozzle 4 is shown, herewith.
Figs. 5 and 6 show still another form of the device in which the fluid or gas enters the chamber 2by any number of pipes from different sides. The same holds true in this case as in the previous described types as to angles, distances and variations in shape of ehamber2 and nozzle 4. These are just a few of the many different types that might be employed.
Figs. 7, 8 and 9 are sections and a plan depicting a typical installation in a vessel howing suggested locations of the devices. and in which 9 is the prime mover actuated by any available force, steam, compressed air, electricity, etc. The prime mover, located at some convenient point, drives either pump 10 or 11, this being accomplished by using either clutch 12 or 13, depending upon which direction the vessel is to be moved. The intakes of two pumps are connected by pipe line 14. The pump 10 or 11 discharges into a pressure chamber 16 or 19 thru pipe 15 with valve 29 and pipe 18 with valve 30 respectively, to which are connected the devices 17 and 20, (various types of which were described in Figs. 1 to 6). by means of leads 31 with valves 32 and leads 33 with valves 34 respectively. These devices are located below the water line of 9 is started, clutch 12 is thrown in,'thereby actuating pump 10 whose suction side draws water from the bow thru devices 17, leads 31, pressure chamber 16, pipe 15, pump 11, which is idle, clutch 13 being thrown To illus- 70 out, and finally thru pipe 14. Pump 10 then discharges into pressure chamber 19 thru pipe 18. To this pressure chamber 19 by means of leads 33 with valves 34 is connected one or more of the devices 20, located in the stern of the vessel thru which the wa- 55 ter is discharged. Due to the tangential inlet into the device, water will be whirled therein and will spread fanlike upon leaving the nozzle, continuing the whirling motion but on an area several times greater than the area of the nozzle. The discharged water being under pressure will. produce corre sponding pressure on the water surrounding the vessel, and thus move it in a direction opposite to that of the thrust. The devices with their whirling effect are acting as propellers. The effect of thrust is probably more complicated and more efficient than the thrust produced by the common propeller because besides act-ing as a propeller, it is cutting into the water and pushing it from the vessel. This thrust is further augmented by the pressure produced by the pump and dissipated upon the surronding water on leaving the device. moved from the bow, thereby reducing the frictional resistance of the vessel passing thru the water. These combined effects will give an efficiency surpassing that of the common propeller.
Should it be desirous to move the vessel backward, the order of procedure would be reversed. Then devices 20 would be the influent ends, the water passing thru leads Furthermore, water is re- 33, chamber 19, pipe 18, idle pump 10,
pipe 14, into pump 11, which is now in action, clutch 12 having been thrown out, and clutch 13 thrown in. The discharge thru pipe 15 enters pressure chamber 16,
from whence it is fed thru leads 31 to one or more of the devices 17 in the bow of the vessel thru which the Water is discharged producing the same action but opposite in effect to the water emitted thru devices 20, resulting in moving the vessel backward.
Figs. 7 and 8 show a suggested auxiliary pressure chamber 22 connected to both pump discharges by pipe line 21 and 23. These connections enable us to draw water from whichever pump is in action by merely using the proper valve. Should pump 10 in use then pipe line 21 with valve 35 would supply the pressure to the auxiliary chamber 22; if, on the other hand, pump 11 is in operation, valve 35 would be shutoff and line 23 would connect by openin valve36 with chamber 22. To this auxi iar pressure chamber 22 are connected ad itional' devices 25, 26, 27 and 28 by means of their respective valves 40, 41, 4 and 43 -and respective pipe lines 24, 39, 37 and 38. In Fig. 7 we show suggested locations of these additional devices, two sets being located in each-side of the vessel, two sets fore and two sets aft. The object of this auxiliary installation with the locations of the devices as shown on Fig. 7 is to facilitate the maneuvering of the vessel. It enables the vessel to be moved about in every. conceivable manner without the aid of tugs or other means.
The sequence of operation is described as follows:
Should it be desirous to move the vessel broadside to port, the valve in line 21 or valve 36 in line 23 is first opened, depending upon which pump is in operation, admitting water under pressure into chamber 22, the valves 40 and 41 connecting devices 25 and 26 respectively are then shut, and those valves 42 and 43, connecting 27 and 28 respectively, are opened bringing these two 27 and 28 into action, thereby moving the vessel to port. Broadside movement to starboard is obtained by reversing the operation, shutting valves 42 and 43, connecting to 27 and 28 respectively, and opening the valves 40 and 41 connected to 25 and 26 respectively, bringing these two devices into action. It can readily be seen that the vessel can be turned around within its own length by operating devices diagonally opposite to each other as, for instance, a sharp turn to port is obtained by using devices 25 and 28 and shutting off 26 and 27, and conversely a sharp turn to starboard is obtained by opening 26 and 27 and shutting off 25 and 28. Turning can be facilitated by bringing any of the devices into action that exert a pressure or a component of pressure in the direction desired. The vessel can be maneuvered without a rudder and without the lost forward or backward motion necessary to bring the rudder into play. It can be readily understood that any number of these additional devices can be placed at different and the most effective locations in the vessel.
It is apparent that many forms of the invstallation or modifications thereof are obtainable or duplicated in the same vessel. In a small boat or in a less expensive installation the pressure chamber may be omitted and the pump be directly connected to the pipe feeding the device or devices. Some installations might avoid the two (pumps and use a double suction pump instea in which case the direction of motion of the prime mover 9 would be reversible. The auxiliary pressure chamber 22 may be omitted entirely, substituting therefor direct pipe connections to the pressure chamber 19 or 16. or direct connections to the pump or pumps, control being obtained by manipulating the proper valves. Altho not absolutely necessary, valves should be placed in all connecting pipe lines. This, enables the repairing of parts without the shutdown ofthe entire plant, and maneuvering is also simplified thereby. Also by using the proper valves, the required pressure caneasily be maintained. Valves can be either mechanically or manually controlled depending upon the financial outlay available.
In an installation in which a gas or air is used as the driving medium instead of water, the plant is identical excepting in this respect that the connecting ipe line 14 is omitted and the intakes o the pumps or pump are connected directly to a gas storage tank or to the atmosphere. In this case air pumps or compressors would be substituted for water pumps. Gas or air instead of water is then pumped into the device or devices or into a pressure chamber or chambers first and then into the device or devices.
Our invention may be embodied with diverse details of form and construction while retaining the distinctive characteristics above described. The arrangement as shown on the accompanying drawings, is only one general form of the installation with the new devices, modifications and variations can be made from the foregoing description without departin from the spirit and scope of the invention as set forth in the accompanying claims.
