Patent GB-202778-A (GB)
Title: Improvements in necking machines
IPC: B31B17/00
Filed: 1922-06-13
Abstract: 202,778. Marks, E. C. R., (Ritchie & Co., W. C.). June 13, 1922. Hollow-ware.-In a machine for forming reduced " necks " on containers, a frame 10 has bearings 11, 12, slidingly accommodating a reciprocating hollow sleeve 13, within which is a second sleeve 14, and within that again, a shaft 15. Appropriate reciprocating motion derived from cam grooves on a shaft 32 is communicated to the parts 13 to 15 by a yoke 21, a bell-crank 35, and a bell-crank 41, respectively. The first parts to move, in a right-hand direction, are the sleeve 14, carrying a cylindrical plunger 45 equipped with expansible spring-controlled sectors 49, and the shaft 15. The plunger is of a diameter equal to the internal diameter of the neck 20 required, and comes to rest when it has reached the proper position shown. The shaft 15 carrying a coned head 51 continues to advance until the coned head has expanded the sectors 49 to the full internal diameter of the container. The outer sleeve 13 carrying a cup-shaped die 18 bevelled at the mouth now advances and, cooperating with the internal plunger, forms the reduced part or neck. The die 18 is now withdrawn, and the shaft 15 moves, withdrawing the coned head 51 and permitting the contraction of the sector 49, whereupon the sleeve 14 is free to recede also. To prevent the sleeve 14 from moving during the contracting action of the die 18, a slide bar 65 having a bevelled end 67 is provided on the frame. It has a depending lug 66 engaged by a yoke 73 carried by the outer sleeve and moves therewith so that during right-hand motion of the sleeve 13 it releases a lock bolt 69 which falls into a notch 72 on sleeve 14 and prevents movement thereof. On reverse movement of the outer sleeve the bevelled end 67 engages a bevelled notch 68 in and raises the lock-bolt, releasing sleeve 14. An intermittently rotated shaft 52 and a recessed carrier 53 form part of a convyer adapted to receive tubes from a source of supply, bring them into register with the neckforming mechanism, and subsequently discharge the necked tubes as required.

Abstract: 849,626. Gramophone pick-ups. COSMOCORD Ltd. Aug. 28, 1957 [May 28, 1956], No. 16400/56. Class 40 (4). [Also in Group XXXVIII] The casing of a piezo-electric transducer is moulded in one piece from flexible material such as nylon, polystyrene or acetate to form two identical housing portions 10, 11 joined by a web 12, the transducing element being housed by folding the casing so that the two housing portions are brought into facing engagement. As shown in Fig. 1, grooves 13, 14 are formed in the web adjacent the housing portions so that the web constitutes an end wall of the casing when the folding operation is carried out, while a hole 24 accommodates a shouldered mounting spindle 20, Fig. 3, the end 22 of which is of square section to prevent rotation. The transducing element 26, Fig. 4, comprises a bender type bimorph which is enclosed in a moulded sheath of resilient damping material such as a plasticised polyvinyl chloride, one end 31 of the sheath being in engagement with the inner surfaces of the folded casing. At the other end of the transducing element the sheath is formed with a cylindrical projection 32 which engages a pivot hole in spindle 20. In addition, the sheath has two driving projections 41, 42 which pass through openings in the casing and engage cantilever stylus arms 33, 34 formed of aluminium alloy, nylon or beryllium copper. Both stylus arms are detachably mounted in slotted grommets 37, 38 fitted into casing openings 40, and either have pins 43, 44 which engage corresponding recesses in the sheath driving projections or are U-shaped so as to engage each projection tip. Terminals 25 are held in position between the abutting edges of the housing portions, and the casing is held closed either by adhesive or by a rivet 45. In a modification, Figs. 5 and 7, the housing portions have recesses 50 which engage spigots 55, 56 of a bifurcated spindle member 54 when the casing is closed. A mounting bracket for the assembly is also described, Fig. 8 (not shown).

Stopping, starting, and tripping arrangements.- Clutches of the rotating pin type, for use in power presses such as printing-presses and presses for stamping or embossing cardboard caps, &c., are automatically operated in such a manner as to produce intermittent half-revolutions of the driven shaft. The slide-operating shaft 2 carries a segmental clutch pin 4 provided with an arm 4x normally engaged by a spring to move the pin to clutching-position and clutch together the rotating fly-wheel 3 and the shaft 2, but adapted' to be stopped at the top and bottom of its rotation by levers 9, 19 to disengage the clutch and stop the shaft. The fly-wheel 3 continuously drives through chain-gearing 21 a shaft 13 which carries an eccentric 12 operating a jointed bar 11 connected by levers 10, 20 to pins 8, 18 carrying the levers 9, 19, which are moved alternately into the path of the arm 4<x> so as to stop the shaft 2 for a period and then release the arm to allow another half-revolution of the shaft. A clutch 22 and brake 23 are used for stopping the rotation of the shaft 13. The pins 8, 18 are spring-cushioned to prevent shocks when the arm 4<x> strikes the levers 9, 19.
