Title: Releasing mechanism for coin-freed apparatus
IPC: G07F5/02
Filed: 1926-08-03
Abstract: 272,354. Wistoft, S. Aug. 3, 1926. Coin action, mechanical-connection: testing' coins.-Relates to vending-mechanism adapted to be released only after the insertion of a millededged coin of the proper size. According to the invention, two slides 1, 4 are provided, the slide 1 being connected to the goods-delivery drawer (not shown), and carrying a pair of spring-connected pivoted grippers 4, 5 which are in the same plane as a coin-receiving member 19 fixed to the slide 14. When a coin is inserted, it falls into the forked end 21 of the part 19, and is supported by a plate 11 projecting from the lower gripper 5. On pulling out the drawer, the slide 1 is then moved forwardly, and the ends of the grippers engage the milled edge of the coin 20, so that the slide 14 moves also.. A pin 23 on this slide engages an inclined surface 2 on a pawl 25, swinging the latter about its pivot so that a tooth 26 on the pawl is moved out of the path of a pin 12 on the slide 1. Without a coin, the slide 14 cannot move along with the slide 1; the pawl 25 therefore remains in locking position, and the .drawer cannot be fully pulled out. Coin-discharging mechanism. - A lever 29, pivoted at 28, has a short arm 31 and a longer arm 30 bearing against a pin 24 on the slide 14. A spring 32 rotates the lever as the slide 14 moves forward under the action of a coin, the arm 30 following the pin 24. Eventually the lever 29 reaches a position wherein a pin 13 on the slide 1. engages the arm 31, and further forward movement of the slide 1 causes the pin 13 to drive the lever, so that this accelerates the movement of the slide 14. Consequenly, the coin-guide 21 moves away from the plate 11, and the coin rolls ,down through an opening 33 into a coin shoot. If a smooth-edged coin has been inserted, the effect of attempting to pull open the drawer is that the grippers 4, 5 are forced slightly away from each other during the limited forward movement of the slide 1. The slide 14 and the blocking-pawl 25 remain in the normal position, and the ineffective coin escapes to a discharge opening 35 through a slot 9 in the gripper 5.

Title: Improvements in and relating to machines for and method of making filled capsules
IPC: A61J3/07
Filed: 1945-07-30
Abstract: 610,821. Moulding capsules. COWLEY,B. C. July 30, 1945, No. 19493. [Class 87(ii)] A capsulating machine having mechanism for moulding capsule shells from a plastic film and for progressively sealing juxtaposed edges of the shells under pressure while holding fluid therein, is characterized by means initially preforming the plastic shells prior to the introduction of the fluid (e.g., a liquid medicement, a paste or a powder) and means actuated during the sealing operation for commencing the injection of a predetermined amount of fluid into the preformed capsule, the injection being completed just prior to the completion of the final sealing thereof Fig. 1-3 show diagramatically suitable mechanism : for achieving this end . Figs. 4-9 (not shown) illustrate in greater detail a preferred form of machine. Each capsule 10, of e.g. soluble gelatin, is formed from two continuous strips of gelatin film 11 and 12, which may be made continuously by flowing melted gelatin from a heated container 14 over a casting drum 15 and oiling rolls 16 past a heater 17, having say hot water or steam but preferably electric coils 18. The two coacting die rolls 22 have mould cavities 20 surrounded by die ledges 23 to cut out the finished capsules 10. At position A air is sucked from the cavity 20 by passage 24, pipe 25 and vacuum pump 28 so that the film is drawn into hemi-spherical (or elongated) shape. This vacuum is maintained until past position B. The half shells approach each other until they contact at position B where the opposed ledges 23 seal the films 11 and 12 together and progressively shear the sealed capsule from the strips as the ledges pass the centre line of the axes of die rolls 22. An intermittent pump 30 forces a predetermined fluid charge through pipe 31 having an end 32 which is thin-walled and has an elliptically shaped orifice, Fig. 3, and is arranged to project into the capsule almost to the sealing position of the leading edges of coacting ledges 23. Just prior to final sealing (a) the trailing edge of the capsule passes the tip of end 32, as shown in Fig. 2 and (b) the vacuum is released in the two coacting mould cavities by holes 27 connected with the atmosphere. The slight elasticity of the gelatine causes the capsule to shrink slightly and expel the remaining air. Pump 33 forces air through pipe 35 and passage 34 to prevent the completed capsules sticking to the mould sides.

Abstract: 901,440. Selective printing. MONROE CALCULATING MACHINE CO. June 2, 1960 [June 9, 1959], No. 19519/60. Class 100 (4). [Also in Group XIX] A calculating machine (see Group XIX) has mechanism for printing, in a cycle of operation, a number set up in a pin-carriage 2 by the operation of the keys of a single-bank keyboard, and also a decimal point in one of a number of possible denominational positions. Printing mechanism.-Type wheels 21, Fig. 1, geared to extensions 18b of the actuators 18 are mounted on swinging plates 23 normally held in the position shown by arms 29 which are allowed only a small pivotal movement relative to the plates 23 and are engaged by a restoring bail 31. Co-operating with each arm 29 is a trigger 33 carrying a finger 36 having an ear 36b co-operating with an arm 38. If the actuator 18 moves from its zero position, the arm 38 raises the finger 36 into engagement with a bail 37 which is rocked when the actuators have moved to their differential positions so as to actuate the triggers 33 and release the arms 29 and plates 23 to swing the type wheels against the platen under the action of springs 30. Projections 29a of the arms 29 hold the type wheels against rotation and ears 33b of the triggers 33 ensure the printing of zeros in orders below significant digits. Printing decimal point.-The swinging plates 23 for the fifth, seventh, ninth, eleventh and thirteenth orders carry slides 22 with decimalpoint type 22a one of which may be raised to effective position by depression of a corresponding one of a row of decimal-point printing key 4. A detent slide co-operates with these keys so that depression of one of them releases a previously depressed key. A clearing key is provided. Depression of a key 4 rocks a lever 45 connected to a lever 47 which raises a cam arm 49 to engage a roller 22b on the decimal-point slide 22. When the swinging plate 23 is released to effect printing in that order, the slide 22 is raised and a decimal point is printed to the right of the digit. If there are no significant digits to the left of the decimal point, a finger 51 rocked by the cam arm 49 raises the finger 36 to ensure the release of the trigger 33 for that order to effect the printing of the decimal point and a zero to the left of it.
