[Classes 83 (ii) and 83 (iv)] Making magneto rotors.-In the manufacture of a hollow metal body, a billet of aluminium or other metal is compressed by a ram in a die cavity of greater diameter and between the ram and the billet is interposed a disc-likemember of slightly larger diameter than the ram, so that the billet is extruded rearwardly around the edges of the disc. As applied to the manufacture of the rotor body of a magneto, an apertured billet 1 of aluminium is pressed in a die cavity 5 by means of a ram 7, the rotor spindle 3 with a disc or flange 4 being inserted in bores in the ram and die so that the flange is between the ram and the billet. On pressure being applied, the billet is extruded rearwardly around the edge of the flange to form a hollow casing and is also extruded rearwardly into countersunk holes in the flange so as to secure the flange and casing together. In order to avoid friction, the ram is of slightly smaller diameter than the flange. In a modified method, the rotor spindle is also formed by extrusion. A billet 14 of aluminium is pressed in a die 15 with a depending axial bore 16 by a ram 17 with an axial bore 18, an apertured steel disc 24 being interposed between the ram and billet. The billet is extruded directly into the bore 16 of the die and rearwardly into the bore 18 of the ram to form the rotor spindle and also around the sides of the ram to form the rotor casing integral with the spindle. Pips 21 at the ends of the bores 16 and 18 suitably shape the ends of the spindle portion. Members 19 and 20 carrying the pips 21 may be formed with a flat so as to constitute a passage for the escape of air. The whole article may be finished in a lathe.

Abstract: 822,590. Automatic bobbin changing in drop - box looms. CROMPTON & KNOWLES CORPORATION. May 21, 1957 [Dec. 3, 1956], No. 16063/57. Class 142(2) When bobbin changing is initiated, the top cell 45 is lifted away from the lower cells 47, 48 by an auxiliary box shifting mechanism to provide a gap for ejection of the spent bobbin; the auxiliary mechanism operates more quickly than the normal mechanism so that a gap is produced even if the cells 47, 48 are being lifted at the same time; the final part of the upward movement of the cell 45, as it meets the fresh bobbin inserted by the hammer 22, is effected freely under its own momentum. A cutter 274 for the spent weft is operated by the relative motion between the cells 45, 47, the cut end T extending to the fabric being moved by the shuttle feeler 30 into the mouth of a suction tube 301. During normal weaving, the cells 45, 47, 48 are shifted as a unit by the normal change box motion, which is modified to cater for the greater distance between the cells 45, 47 than between cells 47, 48 due to the presence of a bobbin deflector 51. The change box at the other end of the loom has a weft feeler for each cell, replenishment being initiated electrically under the control of the dobby, when a depleted shuttle is to be picked to the cell 45.

Abstract: 245,011. Deventer, H. R. van. June 22, 1925. Utilizing vibrations on springs.-A wind-screen wiper comprises a part carrying a wiping strip and means actuated by the motion of the body of the vehicle carrying the windscreen to store and release energy repeatedly whereby the strip is moved over the surface of the wind-screen. As shown, to the rim 2 of the wind-screen are affixed three cylinders 11, 16. 23 having, respectively, pistons 12, 9, 10. The piston 12 is connected to a weight 19 freely suspended by a spring 20 secured to the top of the cylinder 11. An inlet valve 14 is provided in the base of the cylinder 11 which is in communication with the cylinder 16 by way of a pipe 15 and an inlet valve 17. The pistons 9, 10 are connected by a rack member 7 meshing with a toothed sector 6 which is pivotally mounted on a pin 5 and is attached to a bar 4 carrying the wiping strip 3. Jolting of the vehicle when in motion causes the weighted piston 12 to force air into the cylinder 16 and gradually force the piston 9 away from the valve 17 until the end of the piston passes a port 22 in the cylinder whereupon the air escapes and the piston 9 is forced backwards by means of a spring 24 provided in the cylinder 23. Movement is imparted in the strip 3 corresponding to the movement of the piston 9. The invention may be applied to a wiper in which the wiping strip is reciprocated, in a vertical position, across the face of the windscreen.
