1,094,466. Utilizing inertia in machinery. VIBRATOR MANUFACTURING CO. Jan. 5, 1965 [Feb. 17, 1964; Aug. 21, 1964], No. 442/65. Heading F2X. A fluid pressure driven vibrator has an orbiting rotor 60, Fig. 3, a housing 30 for the rotor having a connection 38 to a source of pressurized fluid, the housing having a transverse bore 70 which can be traversed by the perimeter of the rotor as the latter orbits, and an orbiting outlet 64 for fluid co-operable with the rotor. The housing 30 may be of east iron with pedestal legs 31, 32 provided with holes to receive bolts for securing the housing to a surface to be vibrated. Air, steam, exhaust gas, oil or water is supplied to the connection 38 which leads to an annular internal groove 40. A small outlet port 40a is provided in the latter and a cylindrieal baffle ring 41, Fig. 5, with tangential inlet openings may also be provided. In Fig. 3, the housing has side plates 65 held in position by snap rings 66 while in Fig. 5 side plates 86 are held in position by a bolt 95 passing through a bore 93 in the rotor. Fig. 13 illustrates a third construction in which a bolt 134 engages a tapped hole in one side-plate 125 and has a spring 142 and exhaust gas diffuser plate 140 interposed between its head 138 and the second side plate, four exhaust openings 128a and a single tangential vertical inlet opening 118 being provided. The Specification provides graphs and tables for calculating rotor and bore sizes to provide desired frequencies and magnitudes of vibration. |
