摘要： 432,624. Road - traffic signals on vehicles. HASSE, J. N., 12, Walkerville Road, St. Peter's, South Australia. Dec. 10, 1934, No. 35454. Convention date, March 12. [Class 118 (ii)] A roact - trattic signal comprises a tubular member 1 terminating in a housing 4 with uncoloured lenses 5 and 6 directed to front and rear of the vehicle respectively and containing a coloured lamp 10 which is projected into the housing 4 and switched on when a signal is to be given. The lamp is held in its normal position by the spring- pressed locking disc 30 and is projected by handle 27 through link 25 and rod 23, the return being by spring 33 or, if this is not provided, by hand. The link-work may be replaced by a Bowden cable. When the lamp is being projected, movement of the sleeve 14 is stopped by screws 15 co-operating with slots 16 and further movement of the handle 27 moves member 18 against the action of spring 20 to make contact between the conductor 21 and the terminal of the lamp. When the lamp is to be returned to its normal position, the spring 20 forces the conductor away from the lamp to extinquish the lamp. The lenses 5, 6 being uncoloured prevent a false signal being given by the headlamps of another vehicle shining through the housing 4.

摘要： 303,220. Linotype & Machinery, Ltd., Banks, J. N., and Spence, F. Oct. 7, 1927. Delivery apparatus; cutting-apparatus ; grappers and gripper mechanism.-In sheet-delivery mechanism for printing-machines in which a delivery carriage conveys the sheet over the pile during its outward travel and allows the sheet to drop on to the pile during its inward movement, a gripper is provided to take the sheets from the carriage and moves outwards, laterally and downwards so as to deposit the sheet on the pile against front and side lays. As shown, Fig. 1, two grippers or sets of grippers moving laterally in opposite directions are adapted to take the two halves of centrally-slit sheets from tapes 31 which unwind from beneath the sheets to allow them to drop on the piles 32, 33. Each gripper 1, 2 is reciprocated in a bracket 4 extending at an angle to and adjustably carried by a transverse shaft 6 oscillated from the main shaft of the machine by means of a crank 10 and link 11. The upper jaw 1 of each gripper is pivoted at 20 to a slide 21 carrying the lower jaw 2, and a spring 24 tends to hold the jaws in contact. As the slide 21 is moved outwardly an adjustable cam 26 on the bracket 4 engages a roller 25 on the jaw 1 so as to release the sheets at any required time. The roller 25 at the same time moves under and tilts a ramp 27 pivoted on the bracket 4 and normally held depressed by a spring 28 attached to an arm 29 thereon. On the inward movement of the slide 21, the roller 25 first rides up the ramp 27 so as to open the gripper to take a shot from the tapes 31 and then passes over the end of the ramp so as to cause the jaws 1, 2 to grip the sheet under the action of the spring 24. The mechanism for reciprocating the slide 21 in the brackets 4 consists of a bar 13 reciprocated axially in lugs 12 on the brackets 4 through a link 19 pivoted bell-crank 18 engaging a grooved member 17 feathered to the shaft 6. Rack members 14 on the bar 13 mesh with toothed sectors 15 serving to oscillate arms 16 slotted to engage pins 22 on the slides 21. In the case of the one gripper or set of grippers, the sector 15 and arm 16 corresponding thereto are fixed to the same shaft 16 , but a link 30 and crank 16 are interposed to drive the slide 21 of the other gripper or set of grippers.

摘要： 226,623. Linotype & Machinery, Ltd., and Banks, J. N. Sept. 29, 1923. Continuous apparatus for developing and like treatment. - Apparatus for use with a typographical composing machine, comprising a camera, developing, fixing, and washing chambers, mechanism for intermittently advancing a film through the camera and continuously operable mechanism for conveying the film through the chambers, has an actuating device for the intermittently operated mechanism operated by a member of the composing machine which is automatically actuated after exposure of a line of characters. In the construction described, the film 3, Figs. 1 and passes from a spool 11 in a removable film-box 2, past an exposure aperture 9 formed by adjustable shutters 10 in the camera 1. The film then passes through a box 4 containing intermediate conveying bands 38, 39, to developing, fixing, washing and drying apparatus 5, 6, 7, 8, having conveying bands 55, 56 driven continuously, for example by a motor, through gears on guiderollers 59, 60. The film is driven through the camera 1 by means of a pivoted lever 29 actuated intermittently by a member of the composing machine and having a pawl 28 engaging a ratchet 27 on a shaft 25, Fig. 3, driving a shaft 15, carrysprocket-rollers 12, Fig. 4, engaging the film,. through gear-wheels 25, 24, 21. The stroke of the lever 29 can be varied to vary the extent of advancement of the film by means of an adjustable eccentric 31 against which is is drawn by spring 30. The sprocket-rollers 12 and the rollers 13 and the other guide rollers may be adjustable on their shafts to take films of different widths. The film then passes between cutting blades 35, 36 to conveyer bands 38, 39 which may be intermittently or continuously driven from a guide roller 42 by means of a double-faced clutch 54, Fig. 3, splined on the shaft 50 of the roller 42, which can be engaged, by means of lever 66, either with a sprocket-wheel 49 loose on shaft 50 and connected by chain 51 with sprooket-wheel 48, secured on shaft 26, for intermittent drive, or with a sprocket-wheel 52 also loose on the shaft 50 and connected by a chain 53 to a sprocketwheel 65, secured to a roller 59, for continuous drive. A handle 75 is also provided for driving the shaft 50. The conveyer bands have raised edge portions 57, Fig. 6, between which the film may be gripped, and perforations 58. Only one band of the pair may have raised edges, or the upper band may be replaced by two marginal bands. A liquid-spraying arrangement may be provided in any or all of chambers 5, 6, 7 and consists of a tank 67, sprayers 69 for distributing treating-liquid on the film 3, and a rotary pump 70 geared to the driving mechanism of the bands 55, 56 for returning the liquid to the tank 67. The drying apparatus 8 consists of perforated drums covered with absorbent material and internally heated, for example, by gas-jets 72.
