Definitions

  • the blade joint structure disclosed to be used in pumps, blowers, hydrometers, and the like machines, comprises a pair of spaced blades mounted on the ends of a rod extending diametrically through the rotor of machinesof the type referred to.
  • the joint structure is such that the blades have at least two degrees of freedom provided by a blade having a bore in which a clamping means is inserted which itself has a bore at right angles for receiving the end of the rod.
  • the rotor is provided with a slot or bore through which the mounting rod extends and in which it is movable.
  • the means for securing the clamping means to the rod includes a bolt carried by the clamp.
  • FIG.2 6 Claims, 4 Drawing Figures PATENTEDJAH l 5 HT! FIG.2
  • the present invention relates to a joint of two diametrically opposite blades tobe used in pumps, hydrometers similar machines.
  • the rods serve as coupling rods and slide through stuffing boxes which means that there should be two passages which, on their turn,'may cause leakage and friction.
  • the metal rods in the blade blocks which are usually made of a light material, form an extra weight, which is disadvantageous in view of the appearing accelerating forces.
  • a joint- which is characterized in that the joint means comprises a movable rod, the ends of which are clamped within a clamping means in the blades.
  • FIG. 1 represents a hydrometer provided with a pair of blades mounted on a rod according to the present invention
  • FIG. 2 represents rod
  • FIG. 3 is a side view of the pair of blades represented in FIG. 2;
  • FIG; 4 is a section through the clamping means for fixing the joining rod to a blade, taken along the line IV--IV in FIG. 2.
  • FIG. I the pump housing of a hydrometer is schematically represented, said housing enclosing a rotor I and two diametrically opposite blades 2, which are rigidly interconnected by means of a rod 3, which rod is guided through the a bore or slot 4 in the rotor 1.
  • each blade has a bore in which the clamping means 5 is inserted. Further each clamping means 5 is provided with a bore 6 perpendicular to the firstmentioned bore, intowhich the rod 3 passes. The ends of the rod are positioned in the respective bores 6 of the clamping means. By tightening the bolt 7 the end of the rod is clamped within the clamping means. Owing to the fact that the bore through which the rod passes is larger than the diameter of the rod, a rotating movement over some degrees of the rod with respect to the the pair of blades joined by a single blades or blocks in the flat surface is possible. Also a movement perpendicular to the said surface of some tenths of millimetres is possible.
  • the blade blocks can be directed to the surface along which they are moving. As further the ends of the rod are clamped in circular fittings, it is no objection that the diametrically positioned slots in the rotor form .a small angle, as the blade blocks are fixed in the rotor and, consequently, are in the right position. When the blocks are diametrically-worn out,the clamping means can be released for a moment, whereafter the blade blocks are pushed outwardly and thereafter are clamped again. Further this construction has the advantage that in spite of the adjustability the pair of blades can be dismantled and mounted again during which the adjusted measure is re-established. This is obtained by providing a clamping means with a stop pin 8.
  • a machine of the type including pumps, blowers, hydrometers or the like comprising a housing, a rotor mounted in the housing and a blade joint carried by .the rotor, the blade joint comprising a single rod extending through a slotin the rotor, two diametrically opposed blades-each provided with a bore and located at the ends of the rod, means for securing the blades to the ends of the rod, each of said securing means including a clamping means for clamping said rod, and said clamping means being rotatably mounted in said bore, for permitting relative movement between the blade and the clamping means during operation of the rotor.
  • a machine as claimed in claim 1 in which said blades each have a second bore therein communicating with said first mentioned bore, said rod passes through said second bores in said blades, and the diameter of said second bores is greater than the diameter of said rod.
  • a blade joint structure for the rotors of pumps, blowers, hydrometers or the like machines comprising a single rod adapted to extend through a slot in the rotor, two diametrically opposed blades respectively located at and secured to the ends of the rod, a clamping means located in each blade for receiving an end portion of the rod and for connecting the blade and the rod to each other, each said blade having a bore therein, and each said clamping means being rotatably mounted in the bore of its respective blade, for permitting relative movement between the blade and the clamping means during operation of the rotor.
  • a blade joint structure as claimed in claim 4 in which said blades each have a second bore therein communicating with said first mentioned bore, said rod passes through said second bores in said blades, and the diameter of said second bores is greater than the dianceioned bore and wherein one of the clamping eter of said rod. means includes a stop for the end of the rod received 6.
  • a blade joint structure as claimed in claim 5 in therein. which said second bore is at a right angle to said first UNITED .STATES I PATENT OFFICE CERTIFICATE OF CORRECTION Patent No. 3,785,757 K Dated January 15.. 1974 Q Inventor(s) David Paul Stanim It is certified that error appears in the above-identified patent and that said LettersPatent are hereby corrected as shown below:
