IPC: G09C1/08
Filed: 1925-03-25
Abstract: 231,502. Chiffriermaschinen Akt.- Ges. March 25, 1924, [Convention date]. Ciphers. - Relates to ciphering- machines of the kind having a number of rotatable ciphering-rollers provided with electrical contacts on their end faces, the contacts being connected at one end of the series with actuating- members, such as keys, and at the other end with indicating-devices, such as glow-lamps or a writing- mechanism. The rotation of the ciphering-rollers to alter the substitution is effected by toothed pinions, the numbers of teeth on which are prime numbers, or have no common factor, so as to give a very long period before the same arrangement of the rollers recurs. In the arrangement described, four ciphering- rollers 1 are rotatably mounted on a shaft 5 between fixed end-drums 6, 7. Electric currents can be conducted through the device by means of rubbing contacts 3, Fig. 2, which are arranged in the most irregular manner possible, and correspond in number to the signs to be coded, for example, the letters of the alphabet. The ciphering-rollers are rotated by mutilated wheels 21 having small numbers of teeth irregularly arranged. The wheels 21 are carried by shafts 8, which are connected by pinions 12 with a common toothed wheel 16, one of the shafts 8 being rotatable by means of a crank-handle 46. The numbers of teeth on the pinions 12 are different prime numbers, which are also prime to the number of teeth on the ciphering-rollers. The position of the ciphering-rollers is shown by rings of letters 42, which appear in windows 45, and that of the driving-shafts 8 is shown by letters or signs, which appear in windows 33 formed in sleeves surrounding the shafts. The shafts 8 are adjustable endwise into any one of three positions, and carry, in addition to the mutilated wheels 21, fully-toothed wheels 17, by means of which the ciphering-rollers can be separately adjusted into initial position, the pinions 12 and the wheel 16 being then out of gear. In another position of the shafts 8, both the wheels 21 and the fully-toothed wheels 17 are out of gear with the ciphering-rollers, so that a different initial position can be given to the driving-wheels.

Abstract: 491,460. Vehicle couplings ; shackles. BELCH, J. W. March 22, 1937, No. 8388. [Class 103 (v)] [Also in Group XXV] Relates to pin-and-shackle couplings for vehicles of the kind in which at least one pivoted catch 5 is mounted in a recess in the pin 2, and the pin and catch are provided with relatively-inclined co-operating-slots 9, 11, whereby movement of an operating-element 10 in one direction or the other causes the catch to be projected into engagement with the link or to be withdrawn into the pin so as to allow the pin to be moved for uncoupling purposes. According to the invention the catch 5 is adapted to engage an inturned retaining-ledge 4 formed on an external cylindrical element 3 which is arranged on one limb of the shackle coaxially with the pin. In the construction shown in Fig. 1, a single catch 5 having a locking tooth or shoulder 8 is pivoted to the pin 2 between two flat tongues 6, while the operating-element is in the form of a lifting-ring 10, which falls by gravity to render the coupling self-locking, and also releases the catch 5 when an upward effort is exerted upon the ring. In a modification, Fig. 4, a pair of pivoted catches 12, 13 is employed. Complete removal of the pin 2 through the upper limb of the shackle may be prevented by an enlargement on the lower end of the pin.
