Abstract: 696,802. Fishing reels. SHAKESPEARE CO. Jar.. 2, 1952, No. 136/52. Class 48. In a fishing reel wherein a spool 29 is mounted on a spindle 25 axially reciprocable by a driving shaft 5 which also rotates a line pick-up carrier 21, behind the spool, on which are pivoted radially disposed arms 55, 56 formed at the ends of a generally U-shaped pick-up 52 normally spring- urged to inoperative position, the pick-up 52 is automatically moved to operative position on rotation of the carrier 21 in the line-winding direction and to inoperative position on reverse rotation of the carrier. As shown a'spool housing 8 having a conical front 49 with a central guide eye 50 is clamped to a gearbox 2 by a bearing 13 and a nut 14. The spool 29 is adjustably frictionally mounted on the front end of the spindle 25, the rear end of which projects through a tubular shaft 18 of the carrier 21 into an end bearing 28 on the gearbox 2. The spindle is reciprocated by an 'eccentric 27 driven by a manually operated shaft 5 which carries a gear 24 to rotate a bevel gear 23 on the end of the shaft 18. The carrier 21 is clamped to the outer end of the tubular shaft 18 and pivotally receives diametrically opposed ends 55, 56 of the pick-up 52. The end 55 has a coil-spring 57 therearound to bias.the pick-up into its inoperative position shown in Figs. 2 and 5, and the end 56 merges into a looped finger 60 which, in the said inoperative position, projects through registering openings 61, 62, 63 in the gearbox wall, spool housing wall and a wearplate 16 respectively. The edges 64 of these openings form an abutment for the finger 60 which retains the pick-up in inoperative position when the gear 24 is actuated in reverse direction. To prevent the finger 60 engaging in the openings 61-63 during line winding rotation, a keeper 66, which is carried around by the pick-up, is arranged to bridge the width of the openings. On initial line-winding rotation, Fig. 6, the finger 60 engages a curved lead portion 65 on the wear plate 16 to swing the pick-up to operative position and allow rotation of the pick-up. To prevent the line catching behind the spool, the rear spool flange lies under an annular guard member 71 provided on a guard plate 70 rotatably mounted at the rear of the spool.

Title: Improvements in typewriters
IPC: B41J7/02
Filed: 1955-01-04
Abstract: 768,468. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 4, 1955 [Jan. 4, 1954], No. 191/55. Class 100(4) A typewriter has an arcuate group of pivoted type bars 10, a plurality of bars actuating links 20, each operatively interconnected with a type bar, one or more cam surfaces 35 carried on a drum 30 and continuously movable in a path adjacent one end of each link, and one or more actuators for selectively moving the links to bring their ends into the path of the cams which initiate. movement of the selected link and bar to force the bar into contact with the copy. In the construction shown in Figs. 1 and 4 the cams 35 are mounted on the inner surface of the rotating drum 30 and links 20 are normally held out of the path of the cams by engagement of a spring-pressed ball 58 with the pointed end of the link. When a key 40 is depressed it acts through pawl 48, ratchet 49, cable 45, and lever 51 to pull the end of the corresponding link 20 radially outwardly of the drum, and with the ball 58 then acting on the bevelled nose 59 of the link the latter is moved into the path of cam 35 to actuate the type bar 10 against springs 22, 29. The force of spring 29, and hence the strength of the impression on the platen is varied commonly by plate 27 and individually by nut 28. The parts are returned by springs 43, 22, 29. The links may be deflected and advanced by individual electromagnetic means, 'but in the construction shown in Figs. 6 and 7 links 20 are moved into the path of the cams by fingers 96 which normally register with the space between a pair of links, are deflected, to the right or to the left to register with the desired link by electromagnetic means, and advanced axially to move the links by further electromagnetic means. Each finger 96 passes through an aperture in one of a series of tabs 100 on four sector-shaped formes 102 or 104, rotated clockwise or anticlockwise about bars 106, by a common armature 116, according to which solenoid 108 is energized, so that the group of fingers connected with the sector register with one or other of the links associated with each 'finger. The armature 92 of each motive means 90 is connected to a group of four fingers 96, is advanced by energization of solenoid 89, and returned by spring 94, but the arrangement is such that although a group of fingers is deflected by the movement of one sector 102 or 104, and a group advanced by a means 90, only one finger is both deflected and advanced so that one type bar only is actuated. Individual or common switches to complete circuits for energizing solenoids 89, 108 may be closed by actuation of a type key. The invention may be applied to a card operated typewriter.

A cold-cathode glow-discharge indicator tube has a cathode 5, Fig. 1, a main anode 6 and a ring of auxiliary anodes 7. When a glow discharge is initiated by applying a positive voltage pulse of greater voltage than that of the main anode to one of the auxiliary anodes, the discharge remains in the vicinity of that anode. The main anode 6 is in the form of a wire ring and the auxiliary anodes may be shaped as shown in Fig. 5. The gas filling comprises neon and several tenths per cent of argon at a pressure of 20 cms. In Fig. 3 the anode ring 6 is formed with depressions 8 and a mica screen 9 with an atomized cathode coating 11 is arranged over the anode. The screen 9 is provided with slots which may have the shape of figures. In Fig. 7 there are two anode rings 33, 34 with a cathode ring 38 arranged between them. The auxiliary anodes are rods 36 which extend through apertures 35, 37 in the lower anode ring and in the cathode ring. These apertures have a diameter equal to the diameter of the auxiliary anodes plus twice the distance at which minimum ignition voltage occurs. The cathode ring consists of molybdenum and is divided into sectors by nickel-coated areas 39 formed by spraying with nickel oxide and reducing in hydrogen ; the cathode portions between these sectors form burning areas. The anode rings consist of rustless steel. The anode rings are provided with slots 45 to equalize the distribution of energy on high-frequency heating. The lower anode rings is supported on a glass disc 32 and the upper anode ring is supported by rods 42 which are surrounded by ceramic spacers 43. The cathode ring is supported by curved spokes 40. The filling consists of neon and 1% argon at a pressure of 110 mm., but a filling of neon with 0.1% argon is also mentioned. An atomized cathode layer is deposited on the inner surface 46 of the bulb. The auxiliary anodes may be connected to the units of a decade counting circuit and an intermittent voltage, or an alternating voltage if the tube has a suitable rectifying action, is applied to the anode. Alternatively the tube may be powered from a D.C. source and arranged so that the discharge is intermittent.

Abstract: 867,342. Loud-speaker sets. GENERAL ELECTRIC CO. Ltd. Jan. 5, 1960 [Jan. 7, 1959], No. 634/59. Class 40 (4). In a one-to-one telephone intercommunication system using at one station a conventional cradle-type telephone set and at the other station a telephone instrument which comprises a carbon granule microphone and a loudspeaker mounted behind two apertures in the instrument housing, a spring restored plunger supported by the housing, has two electrical contacts connected to it for operating a calling circuit, and itself supports the microphone so that the carbon granules within the microphone are agitated upon operating the plunger. The housing 3 (Fig. 2), in the form of a short hollow cylinder is closed at the bottom by a plate 8 magnetically attached by a metal clip 10 to the permanent magnet 11 of the loud-speaker 2. The plunger button 6, mounted above and so as to cover the loud-speaker aperture 9 has a conical portion 16 which serves to deflect sound waves from the loud-speaker and is supported on a hollow cylindrical member 19 by three pillars 20. Lips 25, 26 on member 19 rest on a partly compressed coiled spring 24, which serves as the restoring device for plunger button 6, lip 26 also carrying a contact 4 and supporting a microphone 1. Another contact 5 is fixed to an insulated annular plate 22 which also carries electric terminals 27 (Fig. 3), for connecting two pairs of leads to the microphone and the loud-speaker, one of the wires in each pair going to a common terminal and to contact 4 and another wire going to fixed contact 5. The microphone and the loud-speaker are connected over separate two-wire circuits to the receiver and transmitter of the conventional set. A battery has one terminal connected to the common wire and the other terminal connected directly to the calling device and also to the transmitter and receiver of the conventional set by way of its cradle switch contacts. It is thus arranged that the calling device operates when contacts 4, 5 are brought together by plunger button 6 and that both two wire circuits are completed when the handset is raised, this operation also lighting a lamp 28 in the telephone instrument through a further calling circuit.
