Definitions

  • This invention relates generally to a power drive mechanism and has for its object the provision of an improved unit of this character which has improved controllin means,
  • the invention being in the nature 0 an imindividually and independently during the rotation of the wheel, the invention further relating to a construction and arrangement in which an individual power unit is provided for each of the blades upon the blade wheel, so as to permit the operation of each.
  • the power units are combined with the wheel body to turn therewith and are arranged to operate the blades directly; and in accordance with our invention the power units for such purpose may consist either of electric motors, or of motors adapted to be operated by gases or liquids under pressure.
  • a further object of our invention is the provision of a simple, compact, self-contained power drive mechanism of the character described and for the purpose set forth, one in which the operation of the blades can be regulated and controlled without the use of troublesome compensating devices such as sprockets, gearing, eccentric discs, and similar mechanical transmitting devices conventionally employed for such purpose.
  • the invention consists in the improve power drive mechanism and in the form,/construction, relative arrangement or arrangements of its parts, as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the sub-joined claims.
  • Fig. 1 represents a central cross section through a wheel body provided with blades and individual electric motors for the blades
  • Fig. 2 represents a central cross section through a hydraulic motor with electric control and compensating means
  • Flg. 7 represents a diagrammatic view showing a modified form of construction
  • ig. 8 represents a diagrammatic view showing a modified construction for synchronizing the operation of the primary and secondary wheel devices.
  • the wheel body 7 is equipped with six blades, of which only blades 1 and '2 situated in the plane of the section and blades 3 and 4 situated behind the plane of the section are Visible.
  • the mobility of the blades with this wheel consists in that each blade may be turned round an axis parallel to the wheel axis.
  • Blade 3 for instance may be turned round axis 56.
  • the electric motors 8 are fastened to the wheel body 7, and their movable parts are connected with the blades.
  • These motors may be made to operate the blades With auniform revolution, with. an uneven rotation or with a swinglng motion,
  • Rotary valve 22 is controlled by rotating magnet 25, the momentary position of which depends upon the electrical excitation of field-magnets 26. By cable 27 the field-magnets are connected with the electric control. If rotary magnet 25 turns under the influence of the control rotary valve .22- opens clearances 20 and 21 in such manner that one side of the cylinder gets into communication with the supply pipe. and the other with the discharge ipe.
  • Fig. 7 we show a synchronizing rocess whereby, duringthe operation o the blade wheel, each blade motor temporarily receives an impulse which tends to bring the blade in a certain position; the release of this impulse from the primary machine, which belongs to this blade motor, or generally from theenergy source or from the control device, is automatically done only when the primary machine is in a position which, corresponds to the above named blade position.
  • Reference character 28 (Fig. 7') denotes the primary'machine and 29 the secondary machine (blade motor) and both machines are supposed as rotary piston machines.
  • the primary machine 28 essentially consists of may be moved to and fro by any suitable I means, for instance by a link bar 38.
  • both casings 30 and 33 and pipings 36 and 37 are filled with a pressure liquid the pressure rise produced on the left side of the machine with the rotary piston swung to the left is communicated-by piping 36 to the right side of secondary machme 29 whereby rotary piston of the secondary machine is swung to the left, that is to say in the same direction as the rotar iston of the primary machine.
  • the liquid displaced from the left side of the secondary machine flows through piping 37 to the right. side of the primary machine.
  • an arm 39 is arranged at the end of which is a head 40 situated between the stops 41 of rods 42 which slide in their longitudinal direction and are loaded by springs 43 in such a manner that the stops 4lare pressed against head 40 of arm 39.
  • the outer ends of rods 42 are provided behind the gearings 44 with stops 45 limiting the movement of rods 42 in the direction of head 40, so that" when the head 40 isin the middle position the springs 43 do not exert any pressure on it.
  • Casing 30 of the primary machine has a canal 46 which, when rotary piston 32 is in the middle position, connects the right and left side of the casing with each other so that in this middle position an equalization of pressure between the two piston sides may take place.
  • rotary piston 32 of the primary machine reaches this middle position both piston sides are temporarily connected with each other and the one-sided pressure exerted on secondary piston 32 temporarily will cease so that, if in this moment rotary piston 35 should be in one or the other direc tion outside of its middle position, one of the two springs 43 can bring arm 39 and thus also rotary piston 35 into the middle position.
  • the trunnion of rotary piston 50 o the secondary machine is hollow and has two openings 52, of which each is situated on one side of piston 50.
  • a rotary valve 53 Inside of the hollow trunnion a rotary valve 53 has been arranged having, two canals 54 and 55 and between them a bridge. This bridge normally closes the two openings 52' of the piston trunnion; canal 54 isconnected through piping 56 (shown in dash-dotted lines) with a pressure-liquid tank (perhaps an air tank of a liquid pump) and canal 55 through piping 57 (shown in dash-dotted lines) with the discharge.
  • Rotary valve 53 is'connected with the trunnion of rotary piston 48 of the primar machine by a gearing 58 in such a manner t at rotary valve 53 moves exactly like rotary piston 48.
  • Figs. 7 and 8 only serve for explanation of the two above mentioned methods, however it shall not be pretended that this synchronizing process maybe performed only with machines of the above mentioned type and only with the indicated constructive means.
  • a device of the character described embodying a rotary wheel body, a plurality of blades and of pistons carried by the wheel body, said pistons and blades being constructed and arranged to provide for the direct operation of the blades by the pistons and independently of the operation of the wheel body, and means for operating the pistons.
  • a device of the character described embodying a rotary wheel body, a plurality of blades and pistons carried by the Wheel body, said pistons and blades being constructed and arranged to provide for the direct operation of the blades by the pistons and independently of the operation of the wheel body, rotaryvalves controlling the operation of the pistons, and means, including a rotary magnet, controlling the operation of said valves.
