Title: Improvements in or relating to container capping machines
Inventor: BERTARIO LUIGI
IPC: B67B3/18
Filed: 1960-03-10
Abstract: 944,323. Applying screw-caps to containers. METALLURGICA MAUCERI S.p.A. March 10, 1960, No. 8462/60. Heading B8T. A machine for fixing caps on containers with screw-threaded necks comprises rotary tools 126, 128 mounted on the spinning unit T for spinning the flanges of the cap into engagement with the thread on the neck of the container. The invention is described as being applied to two types of machine, one in which the spinning unit is reciprocated vertically relative to the platform 10 supporting the containers, and another in which the containers are reciprocated vertically, but in both cases the construction of the spinning unit T is basically as shown in Fig. 4. The spinning unit comprises a tubular element 66 rotated by a motor via the pulley 50, and connected to an inner tubular member 104 by the pin-and-slot arrangement 106, 108. Thus the tubular member 104 is rotated when member 66 is rotated, but can slide axially relative thereto. The member 104 is further provided at its lower end with an annular member 102 formed with slots in which are pivoted supports 110, 112 for spinning tools 126, 128. The tool 126 is prevented from moving axially relative to its supporting spindle 122, but provision is made for allowing such movement of the tool 128 relative to its supporting spindle 124. The upper ends of supports 110, 112 are provided with rollers 118, 120. The unit T further comprises a plate 100, non-rotatably supported by a member 78 coaxial with members 66 and 104. In operating the machine, the neck of a loosely-capped container is urged upwardly through an aperture 136 in the disc 132, until the cap abuts against the plate 100. Further upward movement of the container causes relative vertical movement between the rotating members 66 and 104, until a ring 72 on the lower end of member 66 engages the rollers 118 and 120 causing supports 110 and 112 to pivot to bring the spinning tools into engagement with the flange of the cap on the container. Thus the cap edge is spun tightly round the neck of the container by the tool 126, whilst the flange of the cap is spun into tight contact with the threading of the neck by means of the axially-displaceable tool 128. As shown in Fig. 1, the spinning head T is modified to be reciprocated vertically against the action of spring 86, by a fork 58, the fork being actuated by the same motor 17 which rotates the spinning head.

Title: Improvements in selective locking device for telephone calling dials
IPC: H04M17/02
Filed: 1942-06-22
Abstract: 563,931. Impulse transmitters. WITTGENSTEIN, C. F. June 22, 1942, No. 8538. Convention date, Aug. 6, 1941. [Clase 40 (iv)] An arrangement for preventing the effective dialling of certain numbers employs two cam-wheels, one advanced cumulatively by each setting movement and the other one step for each setting movement, for controlling stops in the path of a third wheel, which in the case of a prohibited number rotates progressively and ultimately operates disabling contacts. These contacts may be capable of being rendered ineffective by authorized persons. As shown in Fig. 4, the cam-wheels 49, 56 are of stepped form and their rims are provided with holes for the reception of cam-members 50 as required. For each digit dialled, the sequence wheel 49 is driven one step and the summing wheel 56 the corresponding number of steps by the shaft 1 through appropriate gearing, as illustrated in Figs. 1-3 (not shown). As these wheels rotate, they control levers 91, 91<1> acting as stops for the wheel 52, which is provided with four rows of holes r<1>, r<2> ... a<1>, a<2> ... , Fig. 8, for receiving pins 73 for cooperating with the levers 91, 91<1>. A plunger 76 controlled by a cam 72 on the shaft 1 co-operates with projections 77 on the wheel 52 to allow its movement only when the dial is normal. If numbers starting with 21, 26 and 27, are to be prohibited, pins 73 and cam-members 50 are inserted, as shown in Figs. 8, 9. After one step of the wheel 49 and two steps of the wheel 56, the levers 91, 91<1> engaging the outer pin r<1> and the inner pin a' are both tilted by cams 50 to release the wheel 52, which on the return of the dial is driven one step by a spring 54 to bring the next pins r<2>, a<2> against the corresponding levers 91, 91<1>. If the second digit indicates a prohibited number these are withdrawn in turn, and the wheel 52 then rotates without further hindrance until its arm 65 operates contacts 58, 59. The wheels 49, 56 are restored by springs when the receiver is replaced and the wheel 52 is returned through a coupling 57, 57<1>. In a modification, Fig. 6, each rim of the summing wheel is effective independently for' one or more prohibited combinations having the same initial digit or comprising that digit only, and holes are provided for an auxiliary cam-member 50<1> which controls an articulated lever 33, 34 acting on the lever 91<1> by a pin 32. When the wheel 52 moves off-normal, a ridge 31 thereon engages the end 34 of the lover 33, 34 and locks it in the position it then occupies. If, for example, the combinations 25 and 46 are to be prohibited, cams 50 are inserted in holes 2 and 7 of the inner rim and holes 4 and 10 of the outer rim, while auxiliary cams 50<1> are inserted in hole 4 of the inner rim and hole 2 of the outer rim, so that both levers 91<1> are withdrawn for the first digit 2 or 4 and the one operated by 50<1> remains locked in order to allow the other one to discriminate as regards tliu second digit.
