In a driving and steering arrangement for endless track vehicles, two parallel sun-ring planet trains comprise carriers 14 respectively driving track wheels 22 through mirror-imaged bevel pairs 16, 17 and gears 19, 20; suns 11 engine-driven through a clutch 2, a multiforward and reverse speed gear 3 and, respectively, gears 5, 7 and the gear 5, a directionreversing idler 6 and a gear 8; and internallytoothed rings 12 having external teeth 23 engaged by an intermediate gear 24 and respectively by a gear 26, brakable at 34, and a gear 28 respectively clutchable at 25, 27 to contraroating meshing gears 31, 32 driven, at 33, by the main engine or a steering motor. In operation, for straight-line driving, through the reducing planet trains, the rings 12 are braked at 34 through the gearing 23, 24, 26, and the clutches 25, 27 are disengaged. For negotiating a curve, the brake 34 is released and either clutch 25 or 27 is engaged to reduce and increase the two track speeds respectively. For on-the-spot vehicle rotation the main drive is stopped and either clutch 25 or 27 is engaged to oppositely drive the two tracks at the same speed. With the clutches 25, 27 disengaged, the brake 34, pre-adjusted, may be used as a slipping safety brake to limit driving torque. Main drive brakes 35 are provided on the carriers 14.

Filed: 1964-12-09
Abstract: <PICT:1067240/C1/1> A glass melting tank furnace includes means for depositing glass making materials as a transverse strip on the surface of a bath of molten glass and means to compact the strip against a previously deposited and compacted strip and to move it over the bath away from the depositing means.  Raw granular batch material from hopper 36 mounted on wheeled framework 35, passes to power driven compartmented feed roll 37 to discharge and form a transverse layer on the surface L of the molten glass G in a doghouse.  The feed supply is controlled by gauge plate 45. Simultaneously cullet from hopper 50, also on a wheeled framework, falls into a tiltable pan 55 oscillated by motor 58 through rod 59, to control the cullet feed rate, and from thence via plate 56 discharges to form a transverse cullet layer beneath the raw granular batch layer in the doghouse.  These layers so built up, are intermittently pushed forward by water-cooled pusher 65 driven by a reversible electric motor (135, Fig. 5, see Division H2) through a transmission gearing, to compact the deposited transverse strip layer against the previously deposited and compacted transverse strip layer, so forming a blanket with a series of transverse ridges on the surface of the molten glass, which blanket moves, as a whole, towards the melting zone of the furnace.  A circuit (Fig. 6, not shown) incorporating a timing device for the control of the intermittent reciprocation of the pusher 65 is disclosed.  Air pipes (182 and 183, Fig. 1) are provided in the furnace proper to break up the formed blanket of charged batch material.
