Title: Improvements relating to mine shaft conveying apparatus
IPC: B66B17/26
Filed: 1924-12-30
Abstract: 227,116. Rheinische Metallwaaren-und Maschinenfabrik, and Reidelbach, G. Dec. 31, 1923, [Convention date]. Conveying from working face in mines.-Relates to systems of apparatus in which material conveyed from the working face is delivered into the mine cage through a measuring vessel. To ensure regular working of the mine cage, storage bunkers x are arranged in a transverse gallery y crossing the pit eye, and one or more measuring vessels a are arranged to run to and' fro in a gallery beneath the bunkers. Tubs z coming from the working face are inverted and discharged in a vertical rail loop w and the material is delivered by a conveyer v into the measuring vessel a or on to conveyers c leading to the bunkers. The measuring vessel a may deliver the material from the conveyer v direct to the cage b, or it may be run along the cross gallery and filled from the bunkers. In the latter case, two measuring vessels may be used, the one filling whilst the other is discharging.
Patent GB-312970-A (GB)
Abstract: 312,970. Hamilton, R. M. March 2, 1928. Totalizators.-A totalizator is provided with means for continuously indicating the odds and for adjusting the mechanism when a ticket is stamped with the prevailing odds, in order to take account of the sum thus earmarked. Logarithmic conversion apparatus. Each advance of the pool drum 1 operates a lever 10 to exert a pull, through a spring 5, on a cord 6 passing over pulleys 80 - - 85. Each pulley is carried by an arm 90 - - 95 loose on a sleeve on a shaft 11 but connected to the sleeve by a free-wheel clutch. The arms pass through a slot 10 in a plate 19 but at one point there is a gap 101 one edge of which is a curve plotted vertically for log. differences and horizontally for log. values. At each operation of the cord therefore one of the pulleys descends to an extent corresponding with the log. increment and turns the related sleeve. The sleeves are interconnected in cascade by free-wheel clutches and 1 : 10 gearing, the last sleeve being fixed to the shaft 11, and thus the movement is transmitted to this shaft and so to one member 130 of a differential gear. The rotation of the shaft advances the cam plate 19 by means of a screw-thread 14 on the shaft engaging a nut 15 rotarily connected to a cylinder 16 having an internal screwed barrel 17 meshing with a nut 18 on the plate. In this way as the registration proceeds the shaft 11 is moved to a position corresponding with the log. of the value registered and the various pulleys come into action according to the powers of 10 reached. In a similar manner the horse bets registered at 2 are converted into logarithmic movements of the other member 131 of the differential gear through cord 23, plate 20, with slot 220, and shaft 25. Registering odds taken. When a ticket is stamped with the prevailing odds, a drum 3 is correspondingly advanced and this effects through cord 24 and cam slot 210, a rotation of a sleeve 26, slidably keyed to drum 28 which gears with drum 16 and consequently rotates this to shift the cam plate 19 backwardly one step, the cam plate 20 similarly being put back to the same extent by the action of screw thread 29 and nut 31. Indicating and recording the odds. The planet wheel frame of the differential gear carries a contact 140, Fig. 3., adapted to sweep over contact segments 141 wired to indicator lamps 170-174 for showing the different odds of the horse concerned, and to magnets 150-154 arranged in a stamping machine. The magnet in circuit throws a latch 180 into the path of an arm 191 to stop this when a handle 183 is turned, thus bringing a type into position beneath the handle. By depression of the latter the odds at the moment are recorded on a ticket and a circuit is completed to advance the drum 3 one step. Specification 307,816 is referred to.

Title: Indexing mechanism for a rotatable member
IPC: B23Q16/06
Filed: 1963-08-08
Abstract: 980,845. Machine tool details. CINCINNATI MILLING MACHINE CO. Aug. 8,. 1963 [Jan. 15, 1963], No. 31309/63. Heading B3B. [Also in Division G4] In a device for setting the angular position of a member 10, e.g. a machine tool worktable, a coarse position motor 44 rotates the member 10 until a coarse position signal is produced, when fine position signals are also produced and cause a fine position motor 82 to rotate the member 10 by an amount corresponding to the fine position signals. A drum 34 (Fig. 1), which rotates with a worktable 10, has rows of four extendable dogs, e.g. 36, 38, 40, 42, at 4 degrees intervals around its circumference which are set manually in accordance with the required stopping positions of the table 10. To move from one position to the next, a switch is closed (e.g. manually) thus causing a fluiddrive motor 44 to drive the table 10 (and drum 34), via gearing 54, 32 &c. When a row of dogs having dog 42 extended comes opposite a row of switches 1LS, 2LS, 3LS, 4LS, switch 4LS is closed to stop motor 44. Coarse positioning to 4 degrees having thus been accomplished, fine positioning to ¢ degree is done as follows. The dogs 36, 38, 40 actuate a selection of the switches 1LS, 2LS, 3LS to supply the required fine position increment in binary coded form and energize a selection of solenoids 1SOL, 2SOL, 3SOL (Fig. 3) which control valves 110, 136, so as to connect one of eight ports 101 . . . 108 in a cylinder of fine position motor 82 to a pressure return line 68. A pressure supply line 62 is permanently connected to both sides of a piston 86 in the cylinder, so the piston 86 takes up one of eight axial positions and performs the fine positioning via an arm 76, a rack 74 and a gear-wheel 30 rigid with table 10. During coarse positioning, the rack 74 is held away from gear-wheel 30 by a pressure motor 78. In being moved back into mesh with gear 30, rack 74 positions the latter to within ¢ degree preliminary to fine positioning. Disengagement of rack 74 and also zeroizing of fine position motor 82 immediately precede coarse positioning.
