Abstract: 345,029. Transfer mechanism. KRUPP AKT.-GES., F., Essen, Germany. Jan. 31, 1930, No. 3339. Convention date, Feb. 1, 1929. [Class 106 (i).] The externally operated transfer actuating and restoring members of several denominations are arranged to form groups which are so connected that the actuating motions take place group after group whilst the restoring motion is effected in all groups simultaneously at the beginning of the next operation of the machine. When a total is to be taken, this restoring motion is suspended and a total obtained (by means not shown) with the transfer members in an unrestored position. The invention is described with reference to a totalizer of the type having sets of numeral wheels arranged side by side, all the wheels in a set being of the same denomination. The nine numeral wheels 1, Fig. 1, of each set are mounted on the hub 2 of a driving wheel 3 inside which slides a shaft 5 rotatably carrying a rider 6 projecting through a longitudinal slit 7 in the hub 2. The rider engages internal teeth 8 on the numeral wheels, any one of which latter can thus be coupled to the driving wheel 3. All the wheels but the one so coupled are locked by the engagement of their teeth with a slit 11 in a rod 9, Fig. 2, the rod moving with the shaft 5 to bring a recess 13 opposite the coupled numeral wheel. The actuation is transmitted from a wheel 14 through pinions 16, 17 to the driving wheel 3, the pinion 17 being rotatably mounted on an eccentric 18. The totalizer frame swings as a whole about a shaft 21, Fig. 2, to move the driving wheels 3 out of engagement with the pinions 17. On a shaft 19 are mounted tens coupling members 24, each having a tooth 25 extending along its length and co-operating with the tens setting teeth 26 of the numeral wheels. Each coupling member has abutment faces 27, 28, Fig. 4, co-operating with faces 29, 31 of the eccentric 18, and also four teeth 32 .. 35, two of which, 32, 33, are long enough to engage an actuating disc 38, Fig. 5, having one tooth 39 and a locking surface 42. If a numeral wheel passes from " 9 " to " 0," the coupling member 24 moves until the faces 28, 31 abut and the teeth 32, 33 are in the range of the actuating tooth 39. Operation of the transfer shaft 15 then completes the transfer by rocking the eccentric 18 (carrying the pinion 17 of the next higher order) to the left, Fig. 2, the pinion 17 riding over the now stationary wheel 16 to actuate the driving wheel 3. The teeth are arranged spirally around the shaft 15, locking discs 56 engaging the eccentrics 18 until the teeth 39 reach their operative positions. Restoration of parts. The restoration is effected by a rotation of 120‹ given to the shaft 15 at the beginning of an operation of the machine, while the driving wheels 3 are disengaged from the pinions 17. The shaft 15 is next held stationary while the differential actuation of the numeral wheels takes place, the remaining 240‹ of its rotation then effecting transfers as described above. Each member 24 is geared to a restoring pinion 30, Figs. 5 and 7, having teeth 43, 44, 45 acted upon by teeth 47, 48, 49 of a restoring disc 51 secured to the shaft 15. The pinion 30 has also teeth 43, 46 which engage a locking disc 52 having a locking surface 54 containing a gap 53. Normally the mechanism is locked by the engagement of the tooth 43 with the surface 54 and the pinion 17 with the wheel 18. During a transfer the teeth 43 &c. are swung to the left, Fig. 5, and the mechanism then locked by engagement of tooth 46 with surface 54 and of tooth 52 with surface 42. The restoring motion of the shaft 15 causes the teeth 47, 48, 49 to engage the teeth 43, 44, 45 to rotate the wheels 24, 30 into the positions shown in Fig. 5. Seriatim motion of transfer shafts; disengagement of restoring mechanism during total-taking. To reduce the diameter of the actuating discs 38 two coaxial transfer shafts 15, 15<1> are used, the lower shaft 15<1> making its transfer-effecting movement first, the upper shaft 15 then following it, but during the restoring movement both shafts move together. Before a total-taking operation, the drive to the shafts 15, 15<1> is disconnected, the transfer parts thus remaining in their unrestored position. The shaft 15<1> is driven from a wheel 64, loose on the shaft 15, through a pinion 63, coupling pinion 62, pinions 61, 58 secured to a shaft 36 and a pinion 59. The shaft 15 is driven through similar pinions 65, 66, a coupling pinion 67, and three pinions 68, 69, 71. The coupling pinions are rotatably mounted on a shaft 72 which, when a lever 82, Fig. 8, is turned into the total-taking position, is moved about a shaft 73 to bring them out of engagement with their respective wheels, two of the said wheels 61, 68 then being locked by a member 83. Secured to the driving wheels 65, 64 are mutilated pinions 85, 85<1>, each having nine teeth, two of which are cut away for half the breadth to form gaps. 91, 92, Fig. 8. Engaging with the pinion 85 is a driving disc 87 having restoring teeth 88 and driving teeth 89, the disc being secured to a locking disc 93 having surfaces arranged so as to co-operate with the gaps 91, 92 of the pinion 85 in such a way that the latter is either being driven or is locked. Similar discs 87<1>, 93<1> co-operate with the pinion 851, but whereas the restoring teeth 88 on the two discs are in alignment, the driving teeth 89 on the disc 87<1> controlling the shaft 15<1> are advanced with respect to those on the disc 87. The four discs are mounted on a hub 95 which is rotated anticlockwise to effect the restoring movements, is then held for a time and finally rotated to complete the rotation of the shafts 15, 15<1> and thereby effect the transfers. The total motion of the hub 95 is 180‹ per cycle, and this is obtained from a continuously rotating shaft 103 by the following means. Secured to the hub 95 is both a toothed wheel 98 having two broad gaps 96, Fig. 10, and two half gaps 97 and a disc 99 having teeth 100, full gaps 101 and half gaps 102 arranged as shown. Co-operating with the wheel 98 is a toothed segment 109 and a disc 113 having locking surfaces 111, 112. Co-operating with the disc 99 is a driving segment 104 and a disc 108 with locking surfaces 106, 107. The members 109, 113, 104, 108 are secured to the shaft 103, and as this shaft rotates clockwise, Fig. 10, the teeth 104 engage the teeth 100, and causes the restoring operation of the shafts 15, 15<1>. A period of rest then follows in which the locking surfaces 107, 112 engage the gaps 101, 97, after which the teeth 109 engage the tooth wheel 98 to effect the transferring operation.
