IPC: G01L3/22
Filed: 1949-11-16
Abstract: 686,003. Rotary-absorption dynamometers. ESCHER WYSS AKT.-GES. Nov. 16, 1949 [Dec. 16, 1948], No. 29328/49. Class 106 (ii). A dynamometer for measuring the torque exerted by the shaft of a prime mover or the torque absorbed by the shaft of a driven machine, comprises a freely-supported system to which the torque to be measured is applied by means of rotatable parts coupled through gear mechanism to the shaft, in which the freelysupported system is arranged coaxially with respect to. the shaft, and is adapted to swing about the axis of the shaft and in which the rotatable parts and their bearings, the gear mechanism and the shaft and its bearings are all carried by the freely-supported system which is itself supported in the fixed housing of the prime mover or driven machine. To measure the torque of a Kaplan turbine, its shaft 1, Fig. 1, is arranged to drive through gears 2, 3, 4, 5 the rotors 8a, 8b of dynamos A, B whose stators 9a, 9b are rigidly connected to a frame 10 with hollow cylindrical part 11 supported on ball-bearings 14, 15 in the fixed cover 1<SP>1</SP> of the turbine and hollow shaft 16 fixed thereto, while the part 11 itself supports the shaft 1 in ballbearings 12, 13. The frame 11 also carries an arm 17, Fig. 2, to the outer end of which are attached wires 18, 19 which pass over pulleys 20, 21 and carry equal weights 23, 24 to keep the wires taut. In operation the shaft 1 drives the rotors 8a, 8b and their electromagnetic braking action, which may be varied through resistances in the field circuit load circuit or by varying the supply of current to the field circuit from an auxiliary source, is transmitted through the gearing and bearings to the frame 10 and through the arm 17 and wire 18 to the pan of a balance upon which the weight 23 rests and the zero position of the balance is maintained by adding weights to the other pan which, when multiplied by the length of the arm 17, give a measure of the required torque. When the dynamometer is used to measure the torque absorbed by a driven machine, e.g. a pump, the dynamos are operated as motors by replacing their external load resistance by a direct current supply. The number of dynamos or motors may be varied according to the size of the torque to be measured. The dynamometer is particularly applicable to measuring torque exerted on or by models in laboratories.

Title: Spring motor mechanism for toys
IPC: A63H29/06
Filed: 1937-10-28
Abstract: 504,931. Toys. WYRICK, C. E. Oct. 28, 1937, No. 29539. Convention date, Jan. 6. [Class 132 (iii)] A power driving mechanism for toys comprises a rotary power storage member, a rotary driven member and connecting means adapted automatically upon movement of the driven member in one direction to connect the power storage member to the driven member for storage of energy, and means for drivingly connecting the driven member to the storage member upon completion of the storage of energy and operable upon dissipation of the energy automatically to disconnect said driven member from said storage member for free movement. A spool 3 carrying the storage spring 1 carries two gears 6 and 7 engaging respectively with pinions 14<1> and 13 on an idler shaft 10, the ends of which are displaceable in a vertical and horizontal direction respectively. The gear 6 is in constant mesh with the pinion 14<1> which carries a gear 14- able to engage or be released from a gear 20 on the driven axle 17, whilst the pinion 13 which is in constant mesh with a gear 21 fast on the axle can engage or be released from the gear 7. The spring is wound up by pushing the vehicle in reverse, when the gear 21 drives the pinion 13, Fig. 3, which is brought into contact with the gear 7 due to that end of the shaft 10 being raised in the vertical slot 12 by the rotation of gear 21. The weight of the end of the idler shaft that moves in slot 12 is counterbalanced by a weighted frame 26 pivoted on the axle and bifurcated to embrace the idler shaft. When the spring drives the toy, this engagement is released and the gear 6 drives the pinion 14<1> and hence brings the gear 14 into driving engagement with the pinion 20 to drive the axle 17 and wheels 22, due to that end of the shaft 10 moving horizontally in the slot 11. When the spring has run down, the pinion 14<1> pivots about the teeth of the gear 6 to bring the gear 14 out of engagement with the pinion 17 to allow free-wheeling. In a modification of the power-charging transmission, as shown in Fig. 6, the shaft 10 is omitted and the pinion 13 is rotatably journaled in a U-shaped shifting frame 40 pivotally mounted on the axle shaft 17, the movement being limited by lugs 41, 411. In a modification of the power-driving transmission, as shown in Fig. 9, the shaft 10 and slot 11 are omitted and the gears 14, 14<1> are carried by a pendant 43, the swinging movement of which is limited by lugs 45, 46.
