Abstract: 25,208. Steinm³ller, L. Nov. 13. Liquid meters.-Meters of the tilting - chamber type are constructed so that the tilting movement is divided into two periods, during the former of which the supply ladle is, by the interposition of a second tilting ladle, so adjusted that the amount of liquid thus supplied to the tilting vessel, which has been almost filled, remains constant, and is independent of the capacity of the liquid meter, the supply being cut off entirely by the second tilting movement of the tilting - vessel. Figs. 1 and 3 show one form of the apparatus. Two tilting-vessels 1, 2 are pivoted on knife-edges and fitted with discharging siphons 3, a weight 4 being secured to the back of each of the vessels. Liquid is supplied to the tank 6 and enters the compartments of the tilting ladle 10, which is pivoted on a shaft 9 provided with arms 16, 17, of which the former operates a lever 21 pivoted on the shaft 20 and supporting the funnel 23, and the latter carries curved segments each having a projection 18 or 19. A small tank 7 is mounted in front of the tank 6, and communicates with it by a passage 8, The tank 7 is provided with an overflow 24 and orifices 25, 26 discharging into the funnel 23. Cams 32, 33 carried on bent levers 28, 29 connected to the backs of the vessels 1, 2 act as stops for the projections 18, 19. In the frame 5 are mounted sliding rods 40, 41 attached to a pivoted lever 43, shown in Fig. 2. This lever is actuated by stops 44, 45 on the sides of the vessels. A tube 46 containing a ball 48 is secured to each of the weights 4, and when the vessel is in its upward position the ball rests on the rod 49. In the position shown, liquid is being fed by all three openings 24, 25, 26 to the vessel 1. The lever 17 is held in its extreme right position by the pressure of the stop 18 on the cam 32. The bolt 40 is fully protruded while the bolt 41 is fully withdrawn. When the vessel is nearly full it will begin to tilt and release the lever 17, which is operated by the ladle 10 and moves to the left until the stop 19 meets the cam 32. The lever 21 and funnel 23 are carried to the left until the former is arrested by the rod 40. The opening 25 is now the only one feeding the vessel 1, and this continues until the weight of the added liquid overcomes the weight of the ball 48, which is now carried by the tube frame itself. When this occurs, the vessel is fully tilted and operates the lever 43, so withdrawing the rod 40 and protruding the rod 41. The funnel is now fully tilted, and all the liquid is fed to the vessel 2 while the vessel 1 is discharged by the siphon 3. A modified form of the controlling-device for the funnel 23 is shown in Figs. 6, 7, 8, and 9. The tilting ladle 10 is replaced by a pivoted trough 54 in which runs a ball 55 whereby the recoil due to the backward movement of the two vessels is avoided by causing this movement to effect the reversal of the trough. The lever 65 carrying the funnel 23 is loosely mounted on the shaft 20 and is operated by the projections 64 carried by arms keyed to the shaft 20. The arm 56 keyed to the shaft 20 carries projections 57, 58 which engage stops 59, 60 on the vessels 1, 2. The rods 40, 41 are actuated as in the other form. For the purpose of interrupting the tilting movement, weights 69 are carried on pivoted levers 68 and are supported by rods 70 when the vessel is in its upward position. As the vessel begins to tilt projections 72 on the vessels engage the levers 68. At the commencement of the tilting movement of the vessel, the lever 56 is released, and the projections 64 force the lever 65 over to the left position. The further tilting of the vessel operates the pivoted lever 43, and, by means of the rotating shaft 42 secured to this lever, the double-armed lever 77 actuates the tongue-piece 76 pivoted in the boss 74 secured to the end of the shaft 20. As either of the vessels rises, the projection 78 secured to it operates the shaft 20 and so the trough through the tongue-piece 76.
