  • Patent number: 4602724
    Abstract: A shutter (111) and shutter control mechanism are disclosed, for use in a banknote dispensing machine for closing the outlet aperture. The shutter (111) fixed to a pivoted arm (112) is normally locked by a latch (109) which lodges in a V-shaped notch formed in the end of the shutter arm (112). When a stack of banknotes approaches the outlet aperture, a control circuit (not shown) energises an actuating solenoid (106) which pulls a drive tooth (103) through a linkage (105) against the action of a return spring (107). The drive tooth (103) rotates clockwise until it rests in the position shown in FIG. 3. During its rotation to this position, a drive pin (108) on the drive tooth (103) pushes the latch (109) away from the shutter arm, thus releasing the shutter. Meanwhile a snail cam, (104) rotates anti-clockwise, and eventually engages a cam follower surface on a lower corner of the drive tooth (103), the drive tooth being pivoted close to its center.

  • Patent number: 4600122
    Abstract: In a seed meter in which a pressure differential is utilized in conjunction with a rotating seed disk having a circumferential row of seed cells therein to pick up individual seeds from a seed mass and deliver the seeds to a seed discharge area, the seed cells are uniquely configured for use with seeds such as sunflower seeds which are of relatively long and slender configuration and of relatively low mass. Each seed cell includes a teardrop shaped recess in the side surface of the disk having an aperture extending through the disk from the bottom thereof to communicate the pressure differential to a seed held within the recess. The seed cell includes a projection extending outwardly from the side surface of the disk and having a surface generally continuous with the back wall of the seed cell so as to aid in picking up and retaining a seed within the recess in addition to providing agitation of the seed mass prior to pickup of the seed.

  • Patent number: 4585111
    Abstract: In a manually operated coin slide mechanism, the usual coin receiving coin slide is permitted a full inward stroke regardless of the value or validity of the coin inserted therein. Actuation of an apparatus controlled by the mechanism is governed instead by a secondary slide yieldingly coupled to the coin slide, and whose displacement is dependent upon the value and validity of the coin. The mechanism is thus protected against damage resulting from the use of brute force by vandals, and is further readily adapted to accept coins of different values, since the degree of displacement of the secondary slide can be made dependent upon the coin value.
