Title: Improvements in weighing apparatus
IPC: B65B1/18
Filed: 1922-08-28
Abstract: 207,600. Bates, A. M. Aug. 28, 1922. Automatic-feed weighers; bearings.-A weighing-apparatus, more particularly for filling bags, comprising a main supporting frame, a scale beam pivoted thereon, and a supporting member at the pivot point mounted upon the main frame and adapted to support the scale beam, is characterized by the fact that the supporting member is laterally and longitudinally adjustable with relation to the main frame. The material from a supply hopper B is fed through a series of rotating feeders D<9>, C' to feed nozzles B<5>, to each of which a bag B<6> resting on the cradle I may be clamped by a serrated gripping member B<9>. The bags are jigged by power-operated feet. The cradle is pivoted within a frame H resting on the scale beam J and has an adjustable base to accommodate different heights of bags. The cradle may be tilted into the position shown by dotted lines, after release of a catch I<3>. The frame H is supported on one end of the scale beam J and is steadied by a link H<1> which hooks on to the frame and is pivoted within a longitudinally adjustable housing H<6>. The scale beam, Fig. 8, carries a main poise J<6> and an adjusting poise J<8>. The poise J<6> is adjusted on the beam by means of a screw K<3> clamped within a slot K<9>, and is suspended from the screw by a nut K', Fig. 9, and a cross-pin K' with ends of angular cross-section. The fulcrum of the scale beam J is supported on the framework A', Fig. 15, by means of a supporting member L which may be adjusted laterally by means of set screws and afterwards clamped to the framework by bolts L<10> and a strip L<5>. The bolt holes L<1> passing through the supporting member L are enlarged to allow of the lateral adjustment and also to permit the supporting member to be adjusted longitudinally. The supporting member carries knife-edges M<2> with end projections M<3> against which the curved ends of bearing blocks M' on the beam may abut. When using the machine the flow of material through the nozzle B<5> may be arrested at any desired time by means of a handle B<4> connected to a shutter B<3>. The nozzle B<5> is carried by the frame H and consequently as the bag descends during a filling operation the nozzle also descends and moves out of line with the outlet R', thus automatically cutting off the feed.

Title: Improvements in or relating to foundry moulding machines
IPC: B22C11/04
Filed: 1934-08-15
Abstract: 441,504. Moulding- machines. FOUNDRY EQUIPMENT, Ltd., 15, Victoria Street, Westminster.-(Baillot, A. J. ; Rue Alphonse Helbronner, Saint Ouen, Seine, France) Aug. 15, 1934, No. 23592. [Class 83 (i)] A moulding-machine has a number of fluidpressure cylinders, automatically operated in timed relation, to rotate a mould-carrying table intermittently and to press the moulds thereon. The machine shown in Fig. 1 is operated by hydraulic plungers 28, 42 and 46 controlled by inlet and exhaust valves 78 ... 83 which are operated in the desired sequence by cams driven through variable - speed gear by an electric motor. The plunger 28 is first advanced and a pulley 30 thereon moves a chain 32, which is anchored at 33, passes round pulleys 30, 34 and 35 and is connected to a weight 38, Fig. 3. This is therefore raised and the rotation of the pulley 34 is imparted by a oneway clutch 24 to the table 14 carrying a number of pattern plates 22 and stops 128, capable of vertical movement therein. As a plate 22 approaches the pressing position one of the stops 128 engages the plunger 138, Fig. 5, of a cylinder 132 connected to a reservoir containing oil. Owing to the conical end 140 of the plunger engaging a corresponding seat, the table is gradually brought to rest between a clamping head 54 and the pressing plunger 42. The plunger 46 is next advanced, against a constant counter pressure admitted by a pipe 126, to operate the clamping head as described in Specification 419,654. The plunger 42 then lifts the pattern plate to compress the sand and falls again, stripping the pattern. The clamping head then rises and one cycle is complete. While the plunger 28 is being returned by the weight 38 another weight 152, resting thereon, also falls and, by reason of a chain, raises the end 150 of a lever thereby lifting the stop 128, in engagement with the plunger 138, clear thereof so that the table can be again rotated. In a modification stripping occurs at a different position from compressing but the stripping plunger may be connected in parallel with the compressing plunger. Specification 353,545 also is referred to.
