Title: Improvements in or relating to apparatus for collecting rod-like articles such as cigarettes
IPC: A24C5/354
Filed: 1961-11-03
Abstract: 958,407. Packaging cigarettes. D. W. MOLINS, and MOLINS MACHINE CO. Ltd. Nov. 1, 1962 [Nov. 3,1961], No. 39468/61. Heading B8C. Apparatus for stacking cigarettes or the like in a container comprises a hopper from which the cigarettes are delivered through vanes extending downwards beneath it,a plate with locating means for receiving the cigarettes from the vanes and position them in spaced formation in rows, the cigarettes of a second row received by the plate alternating with those of the first row, and means to transfer the cigarettes from the plate to the container. Means may also be provided to vary the number of cigarettes in adjacent rows. One or two rows may be fed into the container at a time, the latter descending progressively to stack them. The plate may be moved transversely to the longitudinal axis of the cigarettes. In the first embodiment the vanes are arranged in pairs 4, 5, and the plate 8 is fluted as at 9 (Fig. 1). The cigarettes are delivered from the vanes into alternate flutes and then the plate is moved to the right so that a whole row can be formed. A plunger 14 (Fig. 6) then pushes this row into a container and the second row having one less cigarette is then formed. This is achieved by delivering cigarettes into alternate flutes as before but the left-end column is blocked by a blade 22 (Fig. 4) during the formation of the first of the two half rows. The number in all rows may be the same, the blade 22 then being dispensed with. In a second embodiment the vanes are constructed and the plate 8 is fluted as shown in Fig. 6. A row of cigarettes is formed at the first drop, and a plunger 27 moving to the left pushes the bottom cigarette past a hinged portion 28 of a vane 24. The second row is formed with the plunger 27 held against the bottom of the end pair of vanes to prevent discharge of a cigarette therefrom. The two rows are then moved together by the pusher plate to the container. In a third embodiment (Fig. 11) one vane 29 extends below the others. The first row is delivered and then the plate 8 is moved to the left causing the second row to be delivered between the first. The pusher plate moves two rows together into a container but is so constructed to leave the cigarette B5. In a further form the plate 8 is fixed with the relation between the flutes and vanes as described in Specification 958,406 so that one row of cigarettes fills the flutes and the next row the spaces between.

IPC: F16F15/129
Filed: 1966-09-07
Abstract: 1,155,729. Damped resilient couplings. FORD MOTOR CO. Ltd. 7 Sept., 1966 [23 Nov., 1965], No. 39989/66. Heading F2U. In a clutch disc assembly for motor vehicle transmissions, a driving plate 18 having arms 22 with friction facing material 23 riveted thereto is connected to a driven hub 12 by one or more tangentially disposed springs 28 and, for damping, torque-responsive friction engaging means. As shown, a plate 15 is connected to rotate with the driving plate 18 by pins 20. The springs 28 are housed in aligned windows 27, 26 and 25 in the plates 18, 15 and a flange 14 of the hub 12. The plates 18, 15 have converting tongues 31, 29 extending into the windows 27, 26 and bearing on the springs 28. In operation, on relative rotation of the plates 18, 15 and the flange 14 the tongues 31, 29 coact with the springs 28 so as to be forced inwardly to clamp the plates 18, 15 against the flange 14 with a force which increases with transmitted torque. Preferably, the springs are such that they cannot be completely compressed by the power available from the vehicle engine. In Fig. 4 (not shown), springs (54) are housed in aligned windows (57), (55) and (56) in a driving plate (52) and a plate (48) riveted thereto and a flange of a spider (46). The plate (48) is located between and abuts at (49), (51), the spider (46) and a flange (43) of a driven hub (42), a snap ring (58) holding the assembly together. The hub (42) is in screw-threaded connection (44), (47) with the spider (46). In operation, friction in the threaded connection (44), (47) transmits a portion of the torque through the spider (46) causing compression of the springs (54) and damping frictional forces to arise at the contact surfaces (49), (51). When the compressive force of the springs overcomes the thread friction, the spider (46) rotates with the plates (52), (48) relative to the hub (42) and, as a result, the plate (48) is clamped with a force which increases with transmitted torque.

Abstract: 1280186 Intermittent label feed METOGESELLSCHAFT OSCAR KIND mbH 13 Aug 1969 [14 Aug 1968] 40441/69 Headings B8F and B8R An apparatus for printing and dispensing pressure-sensitive labels I<SP>1</SP> (Fig. 1) adhered to a support tape 2 includes a transport roller 7 having a number of projections on its peripheral surface, the projections co-operating with apertures or marginal notches formed in the support tape at intervals corresponding to the spacing of the leading edges of the labels. The transport roller is intermittently driven through successive angular increments so as to frictionally advance the labels sequentially into a printing and a dispensing position, and the support tape is maintained against the peripheral surface of the transport roller through an angle greater than 90 degrees. In a hand operated device 10 a label tape 2 passes from a supply roll 3, between guides 30 and 47, around a label-separating roller 8, one or more guide rollers 42, (142), (142<SP>1</SP>) (see Fig. 9, not reproduced) and the transport roller 7. Displacement of handle 13 into a casing 11 forces the tip 20 of a pawl 19 over a pin 21 that projects from the lateral surface of the transport roller 7; simultaneously a lever arm pivots a printing device 6 to imprint a label 1 adjacent a platen 5. On release, the handle 13 is spring-returned to return the printing device 6 to its initial position (as in Fig. 1) and cause the pawl 19 to rotate the transport roller 7 through a predetermined angle to feed the label tape 2, peel off the imprinted label 1<SP>1</SP> beneath a pressure roller 9, and bring a new label on to the printing platen 5.  The projections on the transport roller 7 may comprise projecting pins (25<SP>1</SP>) (see Figs. 7, 8, not reproduced) co-operating with apertures (26<SP>1</SP>) or marginal, wave like rims 25 (Fig. 5) that co-operate with wave-like notches 26 in the support tape 2. The dimensions of the projections 25 (25<SP>1</SP>) and notches 26 (26<SP>1</SP>) differ so that only the leading notch and projection co-operate at any time. U.S.A.

Abstract: 1,056,340. Railway vehicle coupling support gear. SOC. ANON. USINES EMILE HENRICOT. Oct. 5, 1964 [Oct. 22, 1963], No. 40449/64. Heading B7T. A coupler 6, Fig. 4, having a draw-bar 15 is supported by a lever 1 pivotally connected at 7 to the bar 15, by a lever 2 pivoted to the lever 1 at 3 and connected to a member 17 fixed to the vehicle frame 18, and by a spring or springs 4 pre-compressed and held between platens 12, 13 by a threaded rod 10 pivoted to the lever 1 at 9 and mounting adjusting nuts 29, 30, Fig. 3, the lever 2 normally bearing against knuckle bearings 11 fixed to the member 17. In operation, a downward force on the coupler 6 as in Fig. 4, causes the levers 1 and 2 to approach more closely together and thus pull on the rod 10. As the platen 12 is integral with the lever 2 then the platen 13 is moved by the rod 10 to compress the springs 4 and produce an upward recentralizing movement on the lever 1 and coupler. If the force on the coupler 6 is upwards, then the levers 1 and 2 tend to move apart and the removable bush 19 on the lever 2 is moved away from the knuckles 11, Fig. 5, at the same time the rod 10 is pushed to cause the platen 13 to move away from the platen 12 and relieve the compression on the springs 4. When the raising force is removed the coupler 6 lowers to its median position, Fig. 2 (not shown). Journal members 22, 23 extending from the bush 19 are guided in openings 24 in the member 17 and prevent the lever 2 from falling when the support returns to its mid-position When the whole gear is in operation swing to one side or the other, Fig. 9, the bush 19 rocks on one of the knuckles 11 and the support system is unbalanced. The axis of the pivot-pin through the draw-bar 15 is however arranged to slope slightly to the vertical so that a re-centralizing force is applied to the coupler when the side swinging force is removed. The longitudinal axis of the drawbar may be adjusted by moving the nuts on the threaded rods through the platens.
