Title: Improvements in or relating to platen printing machines
IPC: B41F1/60
Filed: 1939-06-17
Abstract: 530,975. Machinery guards; brakes. SOLDANS, Ltd., and DOCKREE, B. R. June 17, 1939. Nos. 17766 and 22597. [Class 80 (iv)] The platen 2 of a printing press is reciprocated by an eccentric 4 and connecting-rod 5, the forme being shown at 3. A guard grid 6 is carried by arms 7, 7a fast on a rod 8 pivoted in bearings 8a on the frame 1. The grid is also pivoted on short rods 9 so that it can move inwards towards the forme 3 against the action of a spring 10 which normally holds the grid in a substantially perpendicular position. The grid assembly 6, 7, 7a, 8 is reciprocated by a connecting-rod 11 connected to the rod 5. The rod 11 is pivoted at 12 to an extension 13 of the arm 7, such extension being formed as a step 14 in which the arm 7 rests. When the platen is fully open the grid 6 is in its uppermost position. As the platen moves toward the forme the grid drops until at a point roughly midway between the open and closed positions of the platen, the grid touches the upper edge of the platen. A lever 15 pivoted at 16 carries at its upper end a pin 18 in the path of the grid. At the lower end of the lever is a notch 19, Fig. 3, in which a pin 20 on a lever 21 is adapted to rest. In the event of the operator's hand or fingers coming into contact with the grid, the platen will push the grid and pin inwards to move the lever, release the pin 20 and allow the lever 21 to drop. The falling of this lever is utilized to tension a brake band 22 acting on a flywheel 23. The brake band is adjustably secured at 24 and its free end is connected at 25 to the lever which is pivoted at 26. The movable end of the band is arranged in the direction of rotation of the flywheel so that the flywheel itself tends to wind up the band 22. When it is desired to " wash-up " the press, the grid assembly has to be swung back. To prevent this from being done while the machine is running, a rod 27 connected to the lever 15 has a slot in which a pin 29 on a crank 30 on the rod 8 engages, Swinging back the grid assembly pulls the rod 27 and lever 15 and applies the brake. A throw-off. mechanism for the driving belt may be arranged to act simultaneously with the application of the brake. Where the machine is driven by an electric motor, the catch serving to hold the brakeoperating lever may be combined with a switch so that on release of the catch the switch is cut out.

Abstract: 752,965. Winding toroidal coils. MICAFIL AKT.-GES. June 17, 1954 [June 24, 1953], No. 17825/54. Class 83 (4). A machine for winding closed ring cores with thin wire wherein the wire is taken from a tubular wire storage ring 1 which passes through the ring core 5 to be wound and is rotated by rollers 10 is characterized in that the wire 8 during winding is pulled down over an element 6 arranged next to the core and extending laterally into the winding plane so that the wire is given a wavelike deformation and remains tight on the core. The radially slotted wire storage tube 1 is supported by rollers 2 mounted on parallel plates 3, 4 between which the wire passes to the core 5. An element 6 secured to the plate 3 adjacent the cores projects into a slot 7 in the plate 4 and the wire 8, pulled over the element 6 in the second quarter of revolution of the wire storage tube 1 from the core 5, is given a wavelike bend by the element 6 in co-operation with the slot 7 and is held in position on the element 6, Fig. 2, so that the wire turns do not become loose on the core 5. The element 6 may have a radial wire guide projection 9.

Title: An Automatic Vending Machine Control System
IPC: G07F5/22
Filed: 1968-04-16
Abstract: 1,191,208. Automatic vending machine control system. TATEISI ELECTRONICS CO. 16 April, 1968 [20 April, 1967], No. 17859/68. Heading G4V. A vending machine control system having coin-operated switches 11, 12, 13 producing pulses corresponding to value of inserted coins, a reversible counter with stages 16, 20, 24, article selection switches S 1 -S 10  producing pulses corresponding to the value of the article selected, and means 128 and 130 for delivering change. On insertion of a five, ten, or fifty, cent piece one of the switches 11, 12, 13 sends a pulse to the corresponding stage 16, 20, 24 of the reversible counter. Article selection switches S 1 -S 10  activate corresponding flip-flops F 1 -F 10  sending a signal over one of lines L 1 -L 10  to appropriate gates 41-46 through a diode matrix 61-72. Signals from the flip-flops F 1 -F 10  also set a flip-flop F 11  thereby removing the inhibit signal from element 84 and allowing signal generator 82 to pulse counter 80. The counter 80 sends out a signal successively on line 1, to set flip-flop 32 and prepare the reversible counter for subtraction, on lines 2-7, to scan the AND elements 41-46 and pass any input to the corresponding counter stage 16, 20, 24, and on line L 12 . If the result of the subtraction is positive, i.e. the value of the inserted money exceeds the value of the chosen article, the L 12  output sets flip-flop F 13  producing a signal to reset flip-flop F 11  and stop the pulsing of counter 80. The input to element 102 disappears and hence a signal appears at P, causing vending to take place, and on line L 14  setting flip-flop F 14 , Fig. 2, to activate a generator 119. The latter sends out clock pulses to change giving means for 10 cent and 50 cent pieces, respectively, and to the reversible counter stages 16, 20 over lines L 20  and L 21 . Each release from 128 or 130 causes a subtraction from the corresponding stage of the reversible counter and when the counter stages are empty signals appear on L 16 , L 17 , L 18 , inhibiting the vending action and re-setting the flip-flop F 14 . If the result of the subtraction is negative, i.e. the value of the chosen article exceeds that of the inserted money, the signal on L 12  combines with an output L 13  to reset flip-flop F 11  and isolate it but because of the differentiator D6 these signals disappear and then flip-flop F 11  is set again causing the reversible counter to add the price of the chosen article to the value stored in the reversible counter and arrive back at the total value of the inserted coins. Then the money is returned in a similar manner to before except that no signal goes to vending means P. A reset line R and a cancel button PB are also present.

Filed: 1928-06-20
Abstract: 298,973. Royal Typewriter Co., Inc., (Assignees of Myers, L. C.). Oct. 18, 1927, [Convention date]. Letter-spacing mechanism. - In differential spacing-mechanism for machines having types of single and double width, for instance oriental types, the loose dog of the escapement has a normal double-space movement, and the keys for the singlewidth types operate a universal bar to position an auxiliary stop for arresting the loose dog after a single-space movement. The mechanism shown in Figs. 1 and 3 is employed in a typelever machine having lower-case types of single and double width, and uppercase types of double width, the auxiliary-stop device being disabled when the carriage is shifted. The escapement wheel F co-operates with fast and loose dogs H, K on a rocker G having a stop 1 for arresting the loose dog after the normal double-space movement. The escapement mechanism is mounted on the carriage-shift frame B and the rocker is operated by a universal bar S connected to the action links O. An auxiliary stop 4, normally out of the path of the loose dog. is formed on a forked lever 2 which is pivoted on the shift frame and engages a pin 8 on a lever 9 pivoted on a bracket 11 on the framework A. The levers 2, 9 are connected to springs 5, 12 and the lever 9 is formed with stop-lugs 14, 15 for engaging the bracket. The lever 9 is con. nected by a link 16 to an arm 17 on a rock-shaft 18 supporting an auxiliary universal bar 20 having teeth 22 co-operating with the key-levers for the single-width types and the space-bar levers. Key-levers in different banks are caused to impart uniform movement to the auxiliary universal bar by providing the teeth with faces at different levels. The key-levers for the double-space lower-case types register with recesses 21 and do not operate the auxiliary universal bar. When the carriage is in the lower case position the space-bar or the key-levers for the single-width types are effective to project the stop 4, the spacing being thereby limited to a single space. When the carriage is shifted, the lever 2 separates from the lever 9, and the auxiliary universal bar is unable to project the stop 4 so that all the keylevers effect a two-space movement.
