Abstract: 5934. Espenhayn, W., and Hunger, F. O. March 11. [Addition to 22,243/08.] Automatic - feed weighers. - Relates to the liquid-measuring device described in the parent Specification, and consists in (1) making the tilting vessels continuously rotatable and preventing the vibration of the same, (2) arranging that the weighing- beam which is loaded on one side and is turned directly by the tilting chamber shall be raised by the unloaded arm of an auxiliary weighing- beam loaded on one side, (3) arranging the auxiliary flap valve of the supply-diminishing device below the main flap valve, and (4) providing means for conveniently testing the apparatus. Fig. 2 shows a front view of the apparatus in which a number of tilting vessels 2 rotate in one direction upon an axle 3 mounted in the walls of the meter. On the axle 3 is also mounted a disk 9 having as many teeth as there are measuring-chambers, and in front of this is a disk 10 with the same number of radial arms 11 each of which carries a pin 12. When one tilting vessel is partly filled, the pin 12 corresponding to this vessel engages with a pin 18 mounted on one side of a pivoted lever or weighing-beam, the other arm 13 of which is weighted at 14. As the filling proceeds, the pin 12 presses on the pin 18 and raises the weight 14 until the pin escapes. An auxiliary weighted beam 19 co-operates with the beam 13. Its shorter arm rests against the underside of the weight 14 and gradually lifts it while the tilting vessel is filling. In order to prevent the main beam 13 from being swung over as it is raised, a rod 34 attached to the beam 19 co-operates with a pivoted lever 28 in order to bring a catch 27 in position to engage the end of the lever 13. As the beam 19 falls, the rod 34 falls also and allows the catch 27 to free the beam 13, so that as the liquid continues to flow in a diminished stream into the tilting vessel this tilts, after fully raising the weight 14, and discharges itself. A modification of the catch device is shown in Fig. 15. A finger 14<b> is attached to the weight 14<a>, and this engages a pivoted plate 28b attached to the lever 28<1> in order to raise one end of the lever and place the catch 27<1> in position. Buffers 21, 26, 35 are provided for. the weights 14, 20. As the tilting vessel passes the pin 18, the teeth on the disk 9 raise the end of the lever 23, which places the buffer 26 in position and raises the lever 19 so that its roller cannot be struck by the falling weight 14. The gradual diminution of the supply of fluid is effected by an arm 41 connected to the lever 42 and operating the flap valves 36, 38, shown in Fig. 9, through the lever 40. As the valve 38 is raised, the valve 36 is also lifted from its seat, and the falling of the lever 40 allows the large valve 36 to close first. The lever 42 is operated by cam-surfaces 43, 44 on the disk 10, which engage the projection 45. As the lever 13 rises and the lever 19 falls on the buffer, the cam 43 is withdrawn from under the projection 45, and the latter falls on the step 44, so closing the valve 36. Further movement of the tilting vessel closes the valve 38. The counting-device 46 is operated from the lever 42. If it is desired to operate at a distance, the contacts 50 may be bridged by an insulated metal piece 49 carried by the arm 42. A weighted lever 51, the toothed end of which engages a tooth 43, prevents the swinging of the tilting vessel after the emptying operation. In order to adjust and control the measuring-device, a weighing- beam 53 carries a hollow weight 55 and is connected to the arm 11. Liquid placed in the weight up to the marks 57, 58 serves to test the apparatus. In the form of bearing for the main weighing-beam, shown in Fig. 6, the ring 59 supports, cups 60, 61, 62 in which the segments 64 are pivoted. One of the cups is pressed outwards by a spring. The three segments roll upon the axle 66 and are provided laterally with toothed segments which engage laterally with a toothed wheel keyed to the shaft 66, as shown in Fig. 6<a>. Each tilting chamber 11 is so formed that it must be filled to a certain height before it turns so far that the pin 12 engages the pin 18.
