Abstract: 342,818. Maps &c. SPENCER, A. E., The Bungalow, South View Road, Harpenden, Hertfordshire. Nov. 22, 1929, No. 35831. [Class 146 (ii).] A route indicator comprises a map having routes thereon rendered more permeable to light than the rest of the map, and flaps are employed to prevent light falling on to the routes from the back of the map, the flaps being controlled by push-buttons preferably arranged to reset the previously operated button or buttons. The flaps 6 behind any route b are connected to a single button 1 through links, Bowden wires, or electromagnetic connections, and means, such as a row of balls 14, is preferably provided to prevent simultaneous actuation of more than one or more than a predetermined number of buttons. The buttons are each provided with a projection 11 adapted to rock and ride over a spring-pressed bar 13 which engages the projection and retains the flaps in open position until rocked by the operation of another button. The map is preferably printed or mounted on opaque material and the routes are punched in it, light being directed on the back of the map by a mirror 7 or by reflecting-surfaces on the flaps 6. A screen 10 may be provided over the map. The flaps may be coloured to match the map colouring, or the pieces punched from the routes may be secured to the flaps to register with the holes so as to render it difficult to see any route until the corresponding button is actuated.

Title: Improvements relating to loom dobbies
IPC: D03C1/14
Filed: 1934-12-29
Abstract: 446,844. Loom dobbies. BLACKBURN LOOM & WEAVING MACHINERY MAKING CO., Ltd., and WATSON, E., Phoenix Iron Works, Blackburn. Dec. 29. 1934. No. 3724S. [Class 142 (i)] In pick finder mechanism, an endwise movement of a shaft A disengages the dobby driving mechanism from the loom, and lowers an additional catch D on one of the dobby operating levers E, or cams, into position to engage an additional ratchet wheel D<1> on the pattern barrel shaft g, whereby this is turned back, when the shaft A is turned in one direction, whilst rotation of the shaft A in the opposite direction, causes the pattern barrel shaft to be turned forwardly. In one form, endwise movement of the shaft A against spring action causes a forked lever d<1> to turn a shaft d2 provided with an arm d<4> for lowering the catch D by means of a chain d<5> and a clutch fork-lever d<6>, which engages an annular groove in the boss h<1> of a T-lever H. This lever, which is slidably and rotatably mounted on the dobby shaft J and is constantly operated from a crank arm, is then disengaged from the dobby lever E fixed on the shaft J whereby the dobby is stopped. The shaft A is retained in position, after endwise movement, by a catch a<5> Fig. 3, and a wheel a<3> on the shaft is then in gear with wheel K having a crankpin k connected by a rod k<1> to the dobby lever E, so that turning of the shaft A by means of a crank handle causes operation of the lever E, and of the additional catch D carried thereby. It also causes operation of the ordinary push catch on the other side of the dobby which is carried by another lever fixed to the shaft J and engages the ordinary ratchet wheel. This has teeth pointing in the opposite direction to those on the additional ratchet wheel D<1>. When the rod k<1> is in a raised position, both catches are raised from their ratchet wheels by fingers such as d<9> on a shaft L having an arm d<8> with a projection resting on the rod k<1>, and consequently turning of the shaft A in one direction or the other causes the pattern barrel to be turned correspondingly backwards or forwards. On release of the catch a<5> the shaft A returns to normal position, the catch D is raised and the dobby lever E reclutched to the constantly moving T-lever H. A modification is described in detail applied to a dobby for weaving silk, wherein cams for operating the knives are mounted on the shaft of the driving T-lever and carry catches for turning the pattern cylinder shaft backwards or forwards, endwise movement of a shaft such as A unclutching the T-lever from the dobby, whilst a cone shaped part on the shaft allows a weighted arm to fall and rock a shaft which controls the catches. According to the Provisional Specification, studs on the operating lever are engageable by holes on the T-lever and the connecting rod is slotted.

Title: Feed mechanism for a film
IPC: G03B27/73
Filed: 1974-08-23
Abstract: 1486643 Film transport mechanism ZELACOLOR SYSTEMS ESTABLISHMENT 23 Aug 1974 [28 Aug 1973] 37286/74 Heading G2A  In a film transport arrangement in which a film strip 28 passes from a supply spool 29 to a take-up spool 33, film is unwound from spool 29 by a transport member 31 which moves in a direction perpendicular to the path between the spools, so engaging and unwinding the film. The arrangement is used in the apparatus of Fig. 1 (not shown), for making black and white colour separation prints from a coloured transparency or original. The film from spool 29 passes round a guide roller 70 and a pair of sprocket wheels 34, 35 which engage with the film perforations. After passing over the transport member 31 the film passes round a similar pair of sprocket wheels 36, 37 and then on to the take-up spool 33. The two pairs of sprocket wheels are mounted on respective spindles 38, 39. Wheels 34, 35 are connected together by a bar 40, which is itself connected by a friction clutch 41 to the spindle 38, so that if the pull on the film strip becomes too great, frictional slipping occurs. The transport member 31 has two vertical toothed racks 42, 43, which are engaged by gear-wheels 51, 52 mounted on spindle 38. At its upper end is a roller 44 over which the film passes. To advance the film, a motor 60a is switched on, which drives a train of interengaging gear-wheels, causing spindle 38 to rotate. Gear-wheels 51, 52 rotating with spindle 38, drive the vertical racks upwards from the retracted position of Fig. 2, to the raised or extended position shown in full lines in Fig. 4. A spring- loaded cylinder 72 on a spindle 73 has a plate 76 with two fingers (76a, 76b), Fig. 5 (not shown), which enter into the film perforations. Thus as the racks 42, 43 move upwards, film is drawn from supply spool 29, rotating in direction C against a spring 69. When member 31 has reached its upper operative, position, movement of the film is stopped. In this position, the film, which is now in the path of the light entering through the objective lens of the apparatus, bears against a masking plate, and a number of exposures are made through different filters. The motor is now switched on in the reverse direction. Member 31 is driven downwards again to its Fig. 2 position, and the film strip 28 is driven back on to spool 29, now rotating in the reverse direction D. In this retracted position, the motor is again reversed, and the exposed film rewound on to spool 29 is now withdrawn and wound on to spool 33. If the whole process is now repeated, a new unexposed portion of film 28 will be brought into the exposure position behind the mask as member 31 is driven upwards once more. A detailed description is given, with reference to Figs. (not shown) 7-11 of an apparatus for obtaining colour separation images which includes the above film transport mechanism.
