Title: Differential mechanism for motor vehicles
IPC: F16D41/10
Filed: 1920-10-06
Abstract: 173,342. Johnson, J. D. Oct. 6, 1920. Clutches, ratchet; differential gearing. - In order to permit either road wheel of a motorvehicle to over-run the driving-shaft, a central driving member, having slight rotary freedom in bosses, one on each side thereof, operates rocking dogs to grip the inner and outer surfaces of laterally-extending flanges coupled to the two wheel axles. The mechanism is enclosed in an axle casing 15 having bearings 19 for discs 23 which are coupled to the wheel axles 17 and are provided with flanges 25. The driving-member 30 rotates loosely on a short shaft 28 and has a pair of sectors 37, 38 on each side, these sectors being able to rock in sector-shaped spaces in bosses 43 fixed on the shaft 28. This shaft is loosely carried by the discs 23 but tends to rotate therewith, having a spring friction connection 62 at each end. Dogs 48 rock on pins 47 carried by the bosses and have curved slots 49 passed over the flanges 25 of the driven discs, so that when the dogs are tilted they grip the flanges and transmit the driving effort. Four levers 52 are pivoted on each boss, their outer ends engaging with the dogs and their inner ends being engaged by the sector 37, 38. When the driving-member 30 is rotated in either direction the sectors move in the bosses and operate the levers, causing the dogs to tilt and grip the flanges, the drive being transmitted when the sectors bear solidly against the bosses. If either wheel axle tends to over-run the driving- member it automatically frees its flange 25 from. the dogs. In a modification, the levers 52 are dispensed with.

Abstract: 1,033,117. Calculating apparatus; electric selective signalling. TOLEDO SCALE CORPORATION. July 9, 1964, No. 28396/64. Headings G4A and G4H. [Also in Division G1] A weighing machine of the type in which an operator pre-sets the price per unit weight and inserts a printing plate bearing the name of the article being weighed and in which the machine then prints the name of the article, its weight and its price, is characterized in that the printing plate also electrically selects a storage address in a computer so that a record of the total weight and value of each type of article weighed can be obtained. Unit price times weight calculation.-The weighing element 11, Fig. 1, produces one pulse 12 for each increment of weight on the scale. These pulses are shaped &c. 13, 15, and decimally counted 17, 18, 19, 20. Also each of these pulses produces 2, 4, 2 and 1 pulses respectively on four leads 23, 24, 25, 26, and from these a diode network 28 produces nine groups of pulses on nine leads 31 respectively containing 1, 2 ... 8 and 9 pulses. Appropriate groups of these pulses are selected by three ten-position unit price switches 30 and decimally accumulated 39, 40 ... 44, the groups of pulses being entered in parallel into the lowest three orders. Carry storage devices 48 and 53 are provided for the lowest two denominations. When the accumulator is re-set after each weighing, the lowest denomination is set to 5 to effect rounding up. Printing plate.-The printing plate comprises two printing sections 64, 65, Fig. 2, carrying type 90 and 73, 74 respectively, and a third section 95 carrying three projections 67 which correspond to the type of article being weighed and which select the storage address in the computer. In operation, all three sections are clipped together by notched projections 93, 101 and clips 88, 98. The complete plate is supported in the machine by rods 75, and as it is slid into position the storage address-selecting projections appropriately set multiposition switches (Fig. 7, not shown).

A stereophonic pick-up comprises an electrically conductive U-shaped loop 12, Fig. 1, lying between the poles 19, 20 of a permanent magnet, the loop 12 being electrically connected to two transformers such that, when stereophonic records are played, stereophonically related signals are provided at output terminals of the system. The conductive loop 12 comprises two resilient arms 13, 14 together with an extension 11 carrying a stylus 10. The loop 12 is fixed at its ends 15, 16 and engages a damping pad 18. Extension 11 is connected by flexible wire 21 to a terminal tag 22. If the plane of the loop 12 is parallel to the record surface, side-to-side movement of stylus 10 causes the conductive loop 12 to twist so as to induce an E.M.F. across the ends 15, 16 while up-and-down motion of stylus 10 causes the two arms 13, 14 to flex in the same direction so as to induce an E.M.F. between terminal tag 22 and the two ends 15, 16. When the conductive loop 12 is connected to two transformers 30, 31, Fig. 3, and a stereophonic record of the lateral and hill-and-dale type played, the plane of the loop 12 being parallel to the record surface, an output corresponding to the lateral undulations appears at terminals 36 while an output corresponding to the hill-and-dale undulations appears at terminals 38. With a lateral cut monaural record the output is obtained from the ends 15, 16 or from the terminals 36. The circuit of Fig. 4 is for use with 45/45 stereophonic records, the plane of the loop 12 being parallel to the record surface. Alternatively for playing a 45/45 stereophonic record the plane of the loop may be at 45 degrees to the record surface and the circuit of Fig. 3 used.
