Abstract: 380,905. Casting-machines. PEMETZRIEDER, G., 44, Sachsenring, Tempelhof, Berlin. Aug. 10, 1931, No. 22625. [Class 83 (i).] Molten brass or other metal is fed to a stationary dental or other mould d by dipping a supply pipe e into metal in a container a rotating about a vertical or horizontal axis, so that its open end n faces the advancing metal. The runner may then be closed by a valve f and the pipe e moved so that it empties, the solid plug in the valve then being pushed out by means of the holes k<1>, k<2> or a disc valve having a number of passages 4, Fig. 4, may be used. The means for performing these operations and for opening and closing the mould may be interconnected. Moulds.-In a modification the gate s, Fig. 10, is severed and solid metal pushed back into the hotter part of the pipe e by a rod r operated by a lever v which also engages a helical groove x and thus rotates the pipe e. In another modification the pipe e is provided with a small hole w, Fig. 11, which ensures constant flow and thus keeps the metal below it fluid while that above may be water-cooled and is removed with the casting. Destructible or other cores may be arranged in the moulds. The container may be heated internally or externally or both by electric resistances or burners h, i<1>, i<2>, be charged continuously or intermittently and be enclosed in a casing b filled with inert gas or exhausted. Slag on the metal may be removed first or by a separate pipe o, Fig. 7, or be merely thrown aside by a blade m, Fig. 6, so that it does not enter the end n. The pipe e may be of corundum, or of oxide. of aluminium, magnesium, beryllium, zirconium, or thorium, or of other material unaffected by the metal or flux employed. For continuous casing the metal may be supplied to a nozzle s, Fig. 12, which may be heated and consolidates and gives the desired, hollow or solid, cross-section to the metal which may then pass through a water-cooled passage c.

Abstract: 1473317 Roller conveyers SPECIAL PURPOSE MACHINES Ltd 2 May 1974 [12 May 1973] 22734/73 Heading B8A An elevator 66 receives loads from a rollerway 80 when the platform 68 is in its full line lowered position and inclined about a first axis and discharges loads on to a rollerway 82 when the platform is in the raised broken-line position and inclined about the first axis, but on to a rollerway 86 when the platform is in the raised position and inclined about a second axis. As shown platform 68 has ball castors 88 and is inclinably supported on a ball-and-socket 74, 76 such that the platform when raised, by pneumatic device 70, 72, is normally inclined about the first axis. The platform is inclined about the second axis by operation of pneumatic device 94, 96 to shorten anchor chord 90. A skirt 92 depending from the platform prevents load movement from rollerway 80 except when the platform is in its lowermost position, and housing 84 prevents discharge from the platform except in the fully raised position. In operation, with the platform lowered and a load 48 having run thereonto sensor 42 is actuated and the loaded platform would normally be raised. With the load 46 still on rollerway 72 however sensor 40 is actuated and the platform remains lowered. When load 46 is cleared the platform rises and when load 48 passes on to rollerway 82 and sensor 40 the platform is lowered. The feed and discharge rollerways 80, 86 may be other than at 90 degrees. An elevating ram unit (Fig. 4, not shown) may consist of a pair of rams which support a single ram. Elevation may be effected in two stages with a first platform unloading on to a second platform. The platform may have upper and lower parts connected by springs (not shown) so that rollers 178 are uppermost when the springs are uncompressed but wheels 182 are uppermost when the springs are compressed. The tilting of the ram may be controlled manually or by an automatic sensor, and for discharging loads in several directions more than one anchor chord may be provided. The platform may be raised and lowered by an electric motor driving a screw jack or a ground chain.

Abstract: 461,868. Mechanical presses. MASCHINENFABRIK WEINGARTEN VORM. H. SCHATZ AKT.-GES. Aug. 19, 1936, Nos. 22829 and 22830. Convention dates, Nov. 25, 1935 and July 7, 1936. [Class 87 (ii)] In frictionally-driven screw presses, the roller drive for the flywheel, that is fixed axially with respect to the driving rollers, is so designed that without altering the direction of rotation or speed of the rollers, the peripheral speed of the flywheel as the ram descends is different from that which obtains when the ram is ascending. In the form shown in Fig. 1, the screw spindle 6, rotatably mounted in the frame of the press and operating a non-rotatable nut 3 carrying the ram 2, is driven by a flywheel 7 having outer and inner friction rims 8, 9 either of which is adapted to be engaged by a driving roller 15 on the shaft of an electric motor 14. The motor is mounted on an arm 12 that is movable horizontally by a rack and pinion operated from a hand lever 18. A lever 20 for applying a brake to a rim 10 on the flywheel is also provided. In a modification, a pair of friction wheels geared to a stationary motor spindle can be brought into engagement with either rim 8 or 9. In another form, a pair of rollers rotating in opposite directions and at different peripheral speeds are mounted with their gearing to rock about the driving pinion of the motor. Either roller may be brought into contact with the leathercovered periphery of the flywheel. In a modification, rollers 35, 36, Fig. 5, driven at different speeds and in opposite directions engage a belt 32<1> passing around the periphery of the flywheel 7 and over an idle roller 32. The rollers 35, 36 and their gearing are rockable about the motor pinion 34, so that either may drive the belt. In another form, a vertically-suspended motor drives a pair of rollers in opposite directions and at different speeds, either roller being adapted to be brought into engagement with a single internal rim on an axially fixed flywheel. In a modification shown in Fig. 10, the motor 49, is suspended in an arm 46 secured to and serving to guide the ram 2, the nut 3 being fixed in the head 37 so that the spindle-driving system including the oppositely-rotating friction rollers 48, 48<1> moves up and down with the ram. In each case, the gearing is such that the downward stroke of the ram takes place more quickly than the upward stroke.
