Filed: 1953-07-21
Abstract: 738,707. Variable-pitch propellers. STONE & CO. (CHARLTON), Ltd.,J. July 13, 1954 [July 21, 1953], No. 20241/53. Class 114. In a variable-pitch propeller mechanism, the propeller blades 24 are turned for the purpose of pitch adjustment by movement imparted by an axial movement of the propeller shaft 1. The blades 24 are turned around their pintles on the boss 2 by means of a toothed segment formed on the blade root and engaged by a rack 27 held against axial movement by water lubricated tilting-pad thrust bearings 28 secured to the end of the stern tube 6 at the stern 7. Inboard the shaft 1 is supported by a bearing 3 at the bulkhead 4. In the embodiment of Fig. 1 the female thread of a stationary nut 12 is engaged by the male thread of a sleeve member 15 secured to a housing 16 holding the outer race 17 of a roller bearing, the inner race 18 being fixed on a hub 8 secured to the propeller shaft and having splines 11 sliding in splines in a hollow member 9 connected at 10 to the engine shaft. An electric motor 22 drives an axially elongated pinion 21 engaging teeth 20 on the housing 16 to rotate the latter and house the threaded sleeve 15 in the nut 14 so that the sleeve, housing, propeller shaft and boss 2 are moved axially. The relative movement between the toothed segments and the stationary racks 27 turns the blades 24. In another embodiment the screw device is different from that shown in Fig. 1 and comprises a crosshead with which the shaft is engaged axially by a Mitchell bearing, which crosshead is in screw-threaded engagement with rotatable but axially fixed screws. - A housing 42 accommodates a transmitter connected to the pinion 21 for a pitch indicator and switches for controlling the motor 22 to limit the pitch adjustment automatically to prevent overloading of the engine. Specifications 637,839 and 638,113 are referred to.

Filed: 1933-07-27
Abstract: 418,696. Indicating and recording apparatus; weighing-apparatus. SCHENCK EISENGIESSEREI UND MASCHINENFABRIK, C., and DIEHL, K., 55, Landwehrstrasse, Darmstadt, Germany. July 27, 1933, No. 21109. [Class 106 (iv).] In a method of measuring values represented by linear extensions, e.g., the deflections of pendulum levers of weighing scales, the extensions being indicated or printed, a scale is divided into equal sections, the number of sections between the initial and final points of measurement being determined by one measuring device whilst finer subdivisions are determined by travelling the distance between the final point and one end of the section in which the final point lies, such distance being transmitted during this travelling in magnified proportion to a second or further measuring device or devices. The invention is shown applied to a weighing machine. The weight is transmitted to the pendulum lever 2 by a band 4 secured to a sector 5. The pendulum lever is connected to a sector 6 having type 8, a series of projections 9 and a smooth rim part 10. When the pendulum and the sector 6 have taken up a position of equilibrium, a printing lever 20 is depressed by hand. This lowers a link 19 and moves a pawl 17 into engagement with the projections 9. A pad 22 is also moved into contact with the rim 10. The continued depression of the printing lever causes the pad to turn the sector 6 backward to the left until the pawl 17 engages a projection 9. The pad is connected by links 27 to a spring 29. The backward movement of the sector 6 is transmitted by a projection on the links 27<1> to a lever 15 pivoted at 15<1> and connected by gearing 16 to a sector 12 carrying type 13 which prints the lower denominations in the weight. The final downward movement of the printing lever presses an inserted card 25 against the type 13, 8. The invention is stated to be applicable also to galvanometers, ammeters and water-level indicating devices.
