Title: Improvements in and relating to automatic weighing machines
IPC: G01G21/00
Filed: 1921-01-24
Abstract: 158,516. Boulogne, B. Jan. 24, 1921. Automatic-feed weighers.-Relates to an automatic-feed. weigher of the kind in which the weigh-beam and the weighing-receptacle are coupled by a member which allows relative movement between the two, this movement being utilized to control the main feed. According to the invention the coupling member is suspended from the weigh-beam so that the centre of gravity of the coupling member and the receptacle is situated vertically beneath the point of suspension. The weighing-receptacle 1 is suspended by rods 3 from the coupling member consisting of an intermediate lever 4, 5, which is suspended from the weigh-beam 8, 9 by links 7. Liquid from a supply-chamber passes through valves 19, 29 and enters the weighing-receptacle, the increasing weight of which causes the lever 4. 5 to rotate, thus dropping a lever 52 on to a stop 56 and also pushing up and liberating a rod 23. The main valve 19 is connected to the lever 52 and to the rod 23 by a small lever 47, link 44 and bell-crank lever 22, and falls into the closed position when liberated as described above. The weight is completed through the small valve 29, and the weigh-beam 8, 9 rotates and an arm 57 integral with the beam knocks up and liberates a rod 38 connected to a pivoted catch-pan 37 which falls into a position beneath the feed-valves. The movement of the catchpan allows a counterweighted lever 32 to fall and push up the valve 29 so as to stop the feed. Owing to the rotation of the weigh-beam 8, 9 a pin 11 on the receptacle 1 engages a fixed guide 12 and causes the receptacle to rotate into the lower dotted position and allow the liquid to run out at the nozzles 14, 15 until the receptacle is returned by the counterweight 10. The return movement resets the parts in the position shown in Fig. 1. The arm 57 is connected by a pin 60, loop 61 and lever 63 to a dash-pot 69 for absorbing shock. The pin-and-loop connection 60, 61 leaves the weigh-beam free of the shock-absorbing device in its extreme positions. In the arrangement shown in Fig. 2 the intermediate lever 4, 5 co-operates with a spring 74 interposed between the weigh-beam and the weighing- receptacle.
