Patent GB-1173216-A (GB)
Title: Improvements in or relating to Electrically-Driven Toys
Inventor: TSUNODA ICHIRO
IPC: A63H29/22
Filed: 1966-12-13
Abstract: 1,173,216. Steering mechanisms. I. TSUNODA. 13 Dec., 1966 [14 Dec., 1965], No. 55662/66. Heading A6S. The steering mechanism of an electrically driven toy is actuated by a flywheel threaded on a threaded carrier spindle which is rotated by an electric motor; the flywheel is caused to move along the spindle between two limiting positions when the speed of rotation of the spindle is altered and this movement of the flywheel is connected to the steering mechanism by a linkage means. As shown in Fig. 2, when the motor 2 is switched on the flywheel 5, because of its inertia, moves along the spindle 4 to the abutment 6 and power is transmitted from the motor to the left wheel 17a. When the switch 33 is opened the motor slows abruptly and the flywheel moves to the abutment 6a and when the switch is closed moves back to the abutment 6; these movements of the flywheel cause the pawl 22 to advance the ratchet 23 by one tooth. The cam 25, fixed on the same shaft 26 as the ratchet, is rotated and one of its arms B 1  moves from the position shown in full to position B<SP>1</SP>, and the lever 27 moves the clutch shaft 14 in the direction E to engage the pinion 12 with the drive gear 18 whilst maintaining the engagement between the pinion 12a and the gear 18a so that both wheels 17a and 17 are driven by the motor. When the switch 33 is again opened and closed the ratchet 23 is advanced by another tooth and the cam 25 is moved to the position B<SP>11</SP>, whereby the arm B 1  and the lever 27 cause the clutch shaft 14 to disengage the pinion 12a from the gear 18a whilst maintaining the pinion 12 and the gear 18 in engagement; thus drive is provided to the right wheel. During the next off/on operation of the switch 33 the ratchet 23 is advanced to cause the arm B 1  to be disengaged from the lever 27 which is returned by the spring 29 to abut the arm B 3 . The switch 33 may be replaced by a remotely operated switch, operated in response to sound or electromagnetic signals. The drive to the wheels can be provided by a motor separate from the one operating the steering mechanism and a clam coupling or a gear transmission may be provided between the motor 2 and the spindle 4. Fig. 12 illustrates and combined steering and propelling system for a toy boat in which a cam disc 55 attached to the ratchet 23 moves a connecting rod 58 and the tiller of a rudder 59 whilst a propeller 54 is driven by the same motor. InFigs. 13 and 14 (not shown) the steering mechanism of the boat is operated by a rocker 60 and a spring 61 instead of a ratchet.

Abstract: 1367018 Change-speed control FAHRZEUGUND JAGOWAFFENWERK ERNST THALMANN SUHL VEB 5 Dec 1972 56074/72 Heading F2D In a motor-cycle type gear shift mechanism in which ratio changes are effected by angular movement imparted to a cam cylinder 1 by a double-hooked pawl 10 coacting with bolts 3 projecting from the end of the cylinder, the pawl, which is actuated by a pin 11 on an arm 5 fast with a shift pedal shaft, 4, is slidable relatively to the arm so that during its return movement it is deflected against a spring 12 by cooperation between an oblique edge 14 and one of the bolts 3. The return movement is effected by a spring 9 which is coiled round the shaft 14 and has arms lying on either side of a fixed stop 7 and a tongue 8 turned up from the arm 5. Stop lugs 6 on the arm 5 and 13 on a rearward extension of the pawl coact with the fixed stop 7.

The main metal is preferably Fe or an Fe base alloy such as stainless steel and the added metal having an atomic size no more than 15% larger than the main metal may be Sb, Ti, Mo, Sn, Ta, Zn, W. The mesh size of the minor metal additive is preferably smaller than the mesh size of the main metal e.g. mixture of - 200 mesh Fe powder and <0.7 wt per cent - 100 mesh Sn powder.

The drive is actuated by a control fork engaging collar 24 and, via a spring 28, causing the drive mechanism to move to the right so that the pinion 16 meshes with a flywheel, the spring 28 being compressed if meshing is unable to take place because of abutment of teeth. The starter motor begins to rotate after a predetermined movement of the fork and the pinion 16 and the flywheel mesh if they are not already doing so. The driving member 14 is rotated in the direction of arrow a in Fig. 2 and the rollers 40 are wedged against the driven member 18 causing it to be rotated. When the engine starts it drives the member 18 faster so that there is no longer wedging action to keep members 14, 18 rigidly connected and over-running occurs.

Abstract: 1,206,780. Testing balance electrically. BRITISH HOVERCRAFT CORP. Ltd. Dec. 3, 1968, [Dec. 18, 1967], No. 57340/67. Headings G1N and G1X. Apparatus for determining the out-of-balance moment of an object comprises a first platform 11 which is adjustable by means of three screw threaded spindles 13 to tilt the platform 11 in relation to the horizontal, and a second platform 14 on which the object is mounted, the platform 14 being mounted on the platform 11 by a gimbal arrangement including an intermediate member 16 and two pairs of shaft members, only one pair 20, 21 being shown, the other pair being disposed along an axis at right angles to the shaft members 20, 21 at least one of the shaft members of each pair e. g. 21 acting in torsion to limit tilting movements of the platform 14 relative to the platform 11, the torque loads in the torsion shaft members being measured by use of foil strain gauges, as 29, bonded to the shaft members. In use, the object is mounted on the platform 14 which will tilt out of the horizontal if any unbalance is present. By adjustment using the spindles 13 the platform 14 may be brought back to the horizontal, this being indicated by levels 24. The torques in the torsion shaft members are related to the unbalance in the object, and are measured using the foil strain gauges which are connected in bridge circuits coupled to measuring instruments which may be of the direct sealing or null-balance type. As shown only one of the shaft members of each pair acts as a torsion member, the other shaft, rotating freely at one end in a bearing 22, but both shafts may act as torsion members if desired. The torsion members may be interchangeable with others having different torque characteristics to suit the range of out of balance measurements being made.
