Title: Improvements in and relating to Electrical Timing Devices.
Inventor: GRAY JOHN
IPC: G04C15/00
Filed: 1918-04-26
Abstract: 125,766. Gray, J., (Warren Clock Co.) April 26, 1918. Electric clocks. -Hour and minute hands are normally driven through reducing gear by a self-starting synchronous motor run as nearly as possible at a constant speed, and, if the motor fails, the hands are kept going by an ordinary clock movement which is stopped while the motor is driving to avoid the necessity for frequent winding up. Fig. 1 shows the motor a in plan, and' Fig. 2 in elevation, the armature-spindle 21 being vertical. Each of the poles 12, 13 of the field magnet 10 is divided so as to produce a split phase rotating field by means of the coils 14, 15. The rotor is a disk 20 of hardened steel without winding or slots, and when in action is lifted slightly to take the spindle of its bearing. The spindle and worm-gear are enclosed on an oil well 29. Spurgear comprising a wheel 33 loose on the arbor 37 which carries the minute-hand 38 reduces the speed of rotation to one revolution per hour, and a boss 35 connected to the arbor by a friction clutch 36 is driven by a dog 34 on the loose wheel. The centre arbor 71 of the ordinary clock movement is furnished with an arm 70 which bears a second dog 46 for driving the boss. While the motor is running, a lever 52, 53 is held by magnetic attraction in the position at which it prevents the action of the escapement-lever 51. so that the clock movement remains in reserve.

IPC: C23C24/00
Filed: 1935-03-07
Abstract: 453,157. Protecting metal surfaces. COLES, S. O. COWPER-, Rossall House, Thames Street, Sunbury-on-Thames. March 7, 1935, No. 7107. [Class 93] [See also Group XVIII] Metal surfaces, such as iron and steel, are protected from corrosion by the sprayed application in the form of powder of a metallic coating electropositive to the material to be protected, the coating being applied to a previously applied priming-coat. If the priming-coat is penetrated by moisture, a galvanic couple is set up between the metallic layer and the iron or steel, which prevents corrosion. The metal powder may be zinc dust, or a mixture of zinc dust with powdered aluminium or magnesium or both. The priming-coat may be a red-lead paint. The metal powder may be mixed with a volatile liquid, such as petroleum or benzol. The metallic coating may be protected and ornamented by a further coating of any desired colour and appearance.

Abstract: 804,774. Typewriters &c. STORE NORDISKE TELGRAF-SELSKAB A.S. March 7, 1956 [March 8, 1955], No. 7206/56. Class 100(4) Type-wheel machines, ink-ribbon mechanism. A printing mechanism comprises a type-wheel 10 displaceable in letter-space direction on a shaft 12, a hammer mechanism similarly displaceable on shafts 66, 68, and an ink-ribbon guide 70 which is pivotally mounted so that an ink ribbon 62 can be moved from a position immediately in front of the last line of writing to a position wherein the line is visible. The ribbon guides 70 are shaped to turn the ink-ribbon 62 from the printing line through 90 degrees over a roller 86 to a ribbon feeding mechanism comprising a ratchet 84 and a pawl 88 at the end of an arm 90 on a shaft 92 oscillated by an arm 94 coacting with an eccentric 96 on a machine drive shaft 16. The shaft 16 also carries a cam 106 which operates linkage 108, 112, 114 to rock a shaft 72 upon which the ribbon guides 70 are mounted and so, at the appropriate time, pivot the ink-ribbon 62 clear of the printing line. The ribbon may be of two colours and to print in either of these colours the shaft 72 can be raised or lowered by means of a swinging movement of a frame 74, 76 into two positions determined by a spring 122 and two stops 120. In the printing mechanism described, used in ,a page printing teleprinter, which prints matter transmitted in one colour and matter received in another, the frame 74, 76 is shifted into one or the other position by a triangular plate 182 urged so that, either plate 186 engages lug 190 on the frame arm 76, or corner 184 engages a lug 188. The rocking of the plate 182 is determined by linkage and lever mechanism 198, 254, 236, 232, 240 and cranks 218, 214 according to whether the teleprinter is transmitting or receiving. Hammer impression arrangements. The hammer mechanism is mounted on a plate 126 having a socket 128 so it may slide in letter-space directions on the shaft 66. A notch 144, in a boss of the hammer 138, receives an inclined nose 146 on a rod 148 slidably mounted on rollers 150, 152. The rod 148 is formed with a notch 174 to receive impact motion from a bail 168 attached to bell-cranks 162 rocked by cams 158. The amount of impact may be varied by control of the time the bail 168 is in the notch; this is determined by adjustment of an eccentric mounting of the roller 152. Paper guiding arrangements. The paper which receives the imprints, which may be in sheets or a web 36, Fig. 2, is fed over a rod 44 and downwardly along a guiding plate 46, past a feed-roller 48 below the type-wheel 10 and upwardly past printing position guided by cylindrical guides 50. The paper 36 is pressed against the roller 48 by means of counter-pressure rollers 52 on a lever 54 supported on the end of swingable arms 56. The arms 56 are biased so the rollers press against roller 48, but may be moved away by rotation of a shaft 60.
