Title: Improvements in or relating to recording indicator mechanism particularly for telephone installations
IPC: H04M15/38
Filed: 1938-05-09
Abstract: 588,967. Automatic exchange systems. ALBISWERK ZURICH AKT.-GES. May 9, 1938, No. 13860. Convention date, May 7, 1937. [Class 40 (iv)] [Also in Group XL] In type-printing equipment particularly for recording telephone calls, each type wheel, e.g. for successive digits, is set by gear-wheels rotated by a tooth on a shaft which is released for rotation through one revolution per impulse by a constantly running shaft connected to the tooth shaft by an impulse-controlled friction coupling, the tooth being moved step-by-step along its shaft for engagement with successive type-wheels. In the arrangement shown, shafts 4 and 6 constantly driven by shaft 1 are used respectively to set a group of type-wheels I in accordance with the called number, and groups II and III in accordance with the calling number and the tariff rate, re-setting devices being also driven by shaft 1. The operations will be understood by a description of the setting and re-setting operations for groups II and III. The type-wheels are driven by gears 31 engaged by a tooth 30 rotating with and capable of movement along a shaft 13 driven by a friction coupling 8, but normally locked by armature 16 of an impulse receiving magnet 17, the arrangement being such that armature 16 when operated and released by an impulse releases the shaft 13 for one revolution. After each type-wheel is set, the tooth 30 is moved to the next type-wheel by a projection 39 on a rack bar 37 stepped by magnet 34. The tariff is recorded by type-wheel 47 when the tooth 30 engages gear 43, the transmission rates being altered to take into account the fact that the tariff wheel has ten position as against eleven (one blank) for the calling number wheels. Resetting is effected on operation of magnet 53 which clutches shaft 52 to the driving train. A cam 55 restores the rack bar 37 by operating on lever 57 after holding pawl 38 has been released by suitable linkage, the type-wheels being reset at the same time by known means, such as heart-shaped cams (not shown). In a circuit arrangement (not shown), the impulses for setting the type-wheels in accordance with the wanted number are supplied by a relay shunted by a condenser in one of the lines, the tariff impulses being supplied by a relay in an A.C. simplex circuit.

Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1939-05-16
Abstract: 529,063. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V.). May 16, 1939, No. 14562. [Class 28 (ii)] In a slicing-machine, the slice-discharging fly of the stacking-mechanism is detachable by a simple manipulation, not involving the use of a tool, from its operating means and is thus rendered removable from its pivot. The sliceconveyer, also, is detachable, without the use of a tool, from its operating means and thus removable from the machine. As shown, the conveyer 7 consists of superposed arcuate members having slice-engaging prongs 7a and rigidly interconnected by side columns 7b. The conveyer has a hand knob 10 for its head and a plate 11 for its base, the head being freely journalled on the fixed post 8. The plate 11 rests on a rotatable seat 12 secured to a pinion 13 which meshes with a rack reciprocable with the usual carriage. The seat 12 is journalled on a bush 14, secured to the bracket 15, and has two positioning pins 17, 18 which engage holes in the base 11. A recess 21 in the base 11 is registrable, in one position only of the conveyer, with a pin 22 projecting radially from the post 8, the pin extending through a slot 23 in the bush 14. Thus when the conveyer is turned to register the recess 21 with the pin 22, the conveyer may be removed from the post 8 by a simple lifting movement. The post 8 is removably secured to the bracket 15 by a hand-turnable nut 24, the pin 22 engaging the recess 23 to position the post. The fly 9 is operable under the control of a pull-rod 25 against the action of a spring 26. The pull-rod is operated as described in Specification 513,144, and has a pin or roller 28 which engages an open slot 29 in a lug 30 on the fly so that the rod 25 can be disengaged from the fly as shown in Fig. 2. The spring 26 is anchored at one end and secured at the other end to a stirrup 31 freely rotatable on the pivot shaft 27. The stirrup is formed with an inclined face 31a which when the fly is pulled back by the rod 25, is engaged, in wedge manner, with a correspondingly inclined face 32a on a projection 32 on the fly. The wedge action maintains the fly on the shaft 27. To detach the fly, the rod 25 is disengaged therefrom and the fly is swung on the pivot shaft until arrested by a stop 33. The projection 32 is then clear of the stirrup so that the fly may be withdrawn from the shaft. When the parts 7, 8, 9 have been removed, the shock-absorber, associated with the fly-operating mechanism, maintains the cam follower clear of the cam so that the pull rod 25 remains motionless if the machine is used without the stacker.
