Title: Improvements in inking devices for printing machines
IPC: B41F1/40
Filed: 1953-08-12
Abstract: 763,571. Inking-apparatus. HARRISON, W. Aug. 11, 1954 [Aug. 12, 1953], No. 22184/53. Class 100(2) A device for inking and cleaning intaglio printing plates consists of two doctorblades, 4, 5, Fig. 1, arranged at an angle to each other on a rockable shaft 1 by which they are brought alternately into contact with the plate with their planes at an acute angle thereto on opposite sides of a thread or body of ink lying within the angle and are moved in one direction to spread the ink and in the opposite direction to clean the ink off the flat unengraved portions of the plate, the blades being adjustable toward and away from the line of intersection of their respective planes whereby their rocking motion may be limited so as not to break contact with the body of ink on the plate. The bolts 14 securing the blades to their holder 6 may pass through slots extending downwards from the top edge of each blade to permit this adjustment. As shown in Fig. 5 the shaft 1 is mounted at each end in a bearing 2 which slides in a fixed slotted frame 3; between the bearings 2 and ends of the holder 6, the shaft 1 is engaged by bearings 7 of pushrods 9, Fig. 4, by which the device is reciprocated. Where separate end-extensions to the printing plate are provided for instorage, the blade asembly may be arranged so that the blade contact-lines are inclined to the transverse junctions of the end-extensions to assist passage thereover. Helical springs load the holder 6 so that rollers 11, Fig. 5, on levers 10 fixed to the shaft 1, are pressed on to cam bars 12 which may be set into raised or lowered position by slide-bars 8; with the bars 12 raised the blade 4 is adjusted to spread a thin layer of ink on the plate, while with the bars 12 lowered, the blade 5 is adjusted to clean the unengraved parts of the plate. The ink may be applied by gravity, pump, or compressed air feed direct to the printing plate from a container (or a distributer supplied from a separate reservoir) placed between the doctor blades and the plate, which latter may be horizontal, vertical, or upside down. The doctor blades may be of metal, such as hardened and tempered steel, or of cellulose- or amino-plastics, polystyrenes, polyacrylates, polyvinyl derivatives, etc; they may be resiliently mounted by means of helical springs on their shaft, or long flat, curved or comb-like backing springs. The Provisional Specification refers to the use of doctor blades both in the same plane, or a single double-edged blade; also to fluid-pressure or electrical devices to replace the parts 8, 10...12, and to a second doctor-blade assembly or scavenger to follow the first during the plate cleaning operation, with means to clean the bladeedges during their inoperative periods.

Title: Camera
IPC: G03B17/30
Filed: 1966-05-18
Abstract: 1,103,670. Photographic camera. WHITEHOUSE PRODUCTS Inc. May 18, 1966 [May 25, 1965], No.22189/66. Heading G2A. A camera for cartridges 44 having parallel spools connected by a film-carrying strip 46, includes a metering plate 85, which is preferably pivoted about and is slidable to and from the shaft 65 of the winding mechanism, which plate 85 carries a finger 90, the end 92 of which is urged towards that portion of the film 47 having metering slots such that, on operating the winding mechanism, the end 92 engages a slot in the film and the plate 85 is moved by the slot towards the winding mechanism until a lug 94 on the plate 85 prevents further action of the mechanism when an unexposed portion of film is in the picture gate of the cartridge 44. The lug 94 stops the winding mechanism by engaging a ratchet 72 thereof. On releasing the rear shutter (95), Figs.4-6 (not shown), a cam surface (116) thereon acts on finger 90 to move it towards the winding mechanism and thus produce a slack in the film 47, such that when the front shutter (103) completes its movement a tab 118 thereon hits a tab 119 on the finger 90, releasing it from the film whereupon it returns to its initial position. Double exposures are prevented by co-operating areas 111 and 112 on the rear shutter and finger 90. Figs. 19-22 (not shown) disclose a similar arrangement but variable exposure time is possible by means of a movable stop (182), the position of which determines the amount of movement of a single shutter blade (174). The stop (182) may be connected to a conventional flash unit built into the camera such that on inserting a bulb therein, the stop (182) is moved.

Title: Parking apparatus for automobiles or similar vehicles
IPC: E04H6/28
Filed: 1954-07-30
Abstract: 768,102. Mechanical garages. ALIMANESTIANU, M., and KROLL, C. July 30, 1954 [July 30, 1953], No. 22334/54. Class 78 (4). Automobiles are transferred to and from tines 185, Fig. 4, forming parking spaces by tines 170 ... 183 capable of vertical movement, and of movement in their length, relative to a carriage by which they are carried. In the construction illustrated the tines 170 ... 183 are mounted for longitudinal movement relatively to a turntable 91, Fig. 3, carried by a frame 74, 75, 76, 80 capable of limited vertical movement relatively to a lift by which automobiles are conveyed to and from vertically spaced sets of tines 185 on each side of lift shaft. The tines 170 ... 183 are connected by webs in the middle of their length to a member 150 carried by rollers 145 ... 148 from H-section members 130 joined by members 132 and carried in turn from rollers 122 ... 124 carried by members 108, 109 upstanding from the turntable 91. Cables 161 ... 164 secured to the member 150 and to the turntable 91 pass round pulleys 154 ... 157 on the members 132 so that the member 150 carrying the tine is constrained to move twice as far as the frame 132 which is driven by racks 134, 135 and pinions 138, 137 from a motor 142 on the turntable. When the member 150 has been moved to replace the tines 170 ... 183 below a vehicle supported on the tines 185 the frame 74, 75, 76, 80 is raised by cams 68, 69 carried by a common shaft driven by a motor 67 and engaging followers 83, 84 on the frame to raise the vehicle from the tines 185 so that it may be retracted by the tines 170 ... 813 into the lift shaft for conveying to the ground floor. Before reaching the ground floor the vehicle may be rotated at the level of a mezzanine floor providing greater clearance than the storage shelves in order to face the vehicle in the proper direction for driving away. For this purpose the turntable 91, which is carried by a shaft 90 and steadied by rollers 92 ... 95, is rotated by a pinion 101 engaging a gear 100 fast with the turntable. In its normal position the turntable is steadied by rollers 110 ... 113 which engage in channel-section guides 114 ... 117 on the frame 74, 75, 76, 80. Where the garage has a through path on the ground floor, or where the automobiles may be manoeuvred in the basement, the turntable may be omitted. In an alternative construction the vertically-spaced guides 70A, 70B, 71A, 71B for the frame 74, 75, 76, 80 are replaced by horizontally-spaced guides on a lift frame wider than that illustrated.
