Abstract: 8748. Meyer, H. W. April 11. Automatic-feed weighers. - Relates to automatic scales for liquids, grain, and the like, especially for, and described as applied to, thick liquids such as molasses. A tipping-vessel a, Figs. 1 and 2, divided into compartments a<1>, a<2>, is pivoted in the U- shaped lever b which is supported on pins b<3>. Pins b<6> on the outside of the lever b engage large eyes b<7> on the frame, and allow the lever to oscillate slightly so that a pin on the vessel a may clear a stop r when ready for tipping. Each end of the receptacle a has an extension d<1>, d<2>, extending pins e<1>, e<2> carrying rollers f<1>, f<2> and pins g<1>, g<2> on the sides opposite to the roller-pins, A pivoted and adjustably-weighted lever h is engaged by the pins e<1>, e<2> as the vessel tips, thus braking the vessel. As shown, the pin e<1> lifts the lever in sliding beneath it until the pin reaches a projection h<3> on the lever to stop the tipping movement. The lever then sinks down, and the curved edge of the projection h<3>, acting with a second curved projection h<4> upon the pin e<1>, moves the vessel back a small distance, this action preventing shock both to the vessel and the lever. An air or liquid dash-pot brake i may also be provided. The vessel k, in which the liquid to be weighed is stored, has a discharge tube k<1> which is regulated automatically from the vessel a. A fixed shaft m has a screwthreaded part at each end carrying a tube m<1>, to which is fixed a disk o, having an opening o<1> corresponding to the tube k<1>, and a flanged edge o<2> fitting a groove in the tube. When the tube is rotated, the opening o<1> and tube are brought into or out of alinement, the disk being at the same time raised from the casing to reduce friction. A second small opening o<3> in the disk comes opposite the tube k<1>, when the vessel a is nearly full, a pivoted plate p with a corresponding opening p<1> serving to regulate this opening. The tube m<1> carries a bell-crank lever q<1>, q<2>, the arm q<2> being weighted, and the longer arm q<1> being acted upon by the rollers f<1>, f<2>. In Figs. 1 and 2, the parts are shown in the position in which the vessel a<1> is filling through the large opening o'. When the filling is nearly completed, the extension d<1> causes the vessel to tip slightly to the left, Fig. 2, the pin g<1> engaging the fixed projection r. The roller f<1> slides beneath and clear of the arm q<1> of the bell-crank lever, the disk being then rotated by the weighted arm q<2> to the position shown in Fig. 7 so that the opening o<1> is closed, but the small opening o<3> is open, and not closed as in Fig. 7. The liquid then slowly fills the vessel a<1>, the vessel sinks against the action of the weight b<5>, and the pin g<1> clears the projection r and allows the vessel to tip, the end a<2> then coming uppermost. A projection on the vessel (not shown) moves the slide p to close the opening o<3>, as shown in Fig. 7, the pin f acts upon the lever q' and brings the disk o back to its original position, and the lever h brakes the vessel as previously described. The rotation of the lever q<1> causes the slide p to strike a projection p<5> on the tube casing and thus bring the openings o<3>, p<1> into line for future action. Projections p<5>, p<6>, o<4> on the disk o limit its rotation. A counting- apparatus z is actuated by means of the lever z<3> and pins z<1>, z<2>À
