Title: Improvements in or relating to measuring-wheel-meters
IPC: G01F1/08
Filed: 1951-06-04
Abstract: 701,227. Rotary meters. GEHRE, H. June 4, 1951 [Aug. 9, 1950], No. 13227/51. Class 110 (2) The rotor is constructed as a turbine runner and is movable axially in accordance with the fluid being metered, an increase in flow lifting the rotor and enlarging the outlet area which is closed by the rotor when it is stationary. Fixed guide vanes 9 direct the fluid on to rotor vanes 20 and as the rotor, with its upper cap 18, is lifted the angles of the parts of the vanes 9, 20 facing one another vary i.e. both types of vanes are twisted along their lengths. Fluid enters from a duct 4 and passes upwards through a channel 7 and guide and rotor vanes 9, 20 into a volute leading to an outlet 2. In Fig. 1 the right-hand side shows the outlet almost closed, with vanes in telescoped position, and the left-hand side in the open position. The angles of the vanes along their lengths are illustrated in Figs. 3 and 4 (not shown). A member 11, supported by ribs 10, provides a lower guide bearing 12 for the rotor shaft 14 which actuates the counting mechanism, a further guide bearing 13 being located in a cover 16. Pressures are equal on the two sides of the latter, through holes 15. A flared tube 26, on the member 11, co-acts with a skirt 28 to protect the shaft 14 and its bearings from dirt. Parts 29, 21 form a labyrinth seal to separate the space 30 from the outlet. Fluid at low pressure passes through holes 33 into spaces 30, 31 to create the pressure difference on the upper surface 18 of the rotor which is lifted. The meter may be provided with more than one set of guide and moving vanes. A damping disc 40, Fig. 6 (not shown), may be attached to the shaft 14 to prevent a sudden lifting of the rotor. Fig. 7 shows a simplified construction in which the outlet volute is dispensed with and the lower housing part 1 is co-axial with an outer wall 42 which supports the outlet 43. A similar arrangement is shown in Fig. 1 in dotted lines. Vanes 44, Fig. 7, cause the incoming fluid to be whirled. A labyrinth packing 29 co-acts with the side of the rotor 21. In a further arrangement, Fig. 8 (not shown), the rotor is in two parts which move telescopically. The lower shaft is provided with an impeller fan by which it is rotated through the fluid flow. The nozzles leading to the vanes may have different edge-shapes, one half of each being diaphragm like, the other being formed as a curve 58, Fig. 9 (not shown). An auxiliary adjustable nozzle 60, Fig. 1, may be provided to direct a stream of fluid on to the vanes 20, a filter 61 being placed as shown. For the purpose of obtaining smaller velocities of flow of the fluid, a light floater plate 62 may be arranged in the entrance of the tube 7, which may also be of reduced diameter 63. Fig. 10 shows a further modification having a floater plate 62 and an impeller fan 56 on the shaft 14, with inlet guide vanes 66. A nozzle 67, on the plate 62, may be provided to assist rotation of the plate. The plate 62, in its lowest position, may close the inlet.

Filed: 1936-05-13
Abstract: 460,688. Safety razors ; hair clippers. WILKINSON SWORD CO., Ltd., and RANDOLPH, H. B. May 13,1936, No. 13538. [Classes 30 and 131] Mechanical razors and shavers are driven by means such that normally the drive is interrupted, but when the device is applied to the surface to be shaved the drive is made operative, and is interrupted again if the pressure is excessive. In the form shown, a rotary drum 9 with cutters 10 is journalled in a casing 5 pivoted to the handle at 7 and is adapted to be driven from a power shaft 4 by a worm 3 and spring-supported roller 13. Upon the device being applied with suitable pressure, the drum rises and presses the roller into engagement with the worm and the drum is rotated. If the pressure becomes excessive, with consequent danger of cutting the surface shaved, the drum slips past the roller, which yields, and then springs away from the worm and the drive ceases. One edge of the slots 30 in the drum through which the cutters project is formed with a guard comb 22, Fig. 3. An additional guard may be formed by ribs 21 passing across a slot in a plate 12 which forms part of the casing 5. The edge of the blade is slotted at 20 to accommodate the ribs 21.
