Abstract: A locking device for securing the coin box of coin operated vending and amusement machines is provided. An elongated flat locking bar is pivotally connected to the face of the coin operated machine by means of a spring loaded pivot pin for swinging movement parallel to said face between a locking position extending across and in close juxtaposition to the access door of the coin box and an open position permitting access to said door. A locking pin extends through an opening in the free end of the locking bar and a corresponding opening formed in the face of the machine to a point on the interior of said machine adjacent to the coin box. A barrel lock normally provided to lock the access door of the coin box is fitted with a lever having a retaining notch formed therein which is adapted to engage the inner end of the locking pin in its locked position. Access to the barrel lock from the exterior of the coin operated machine is obtained by a suitable opening formed in the locking bar.

Abstract: An apparatus for trimming the wire leads of electronic components mounted on printed circuit boards is provided, which comprises a base plate, an adjustable holding fixture for a printed circuit board fixedly disposed on the base plate, a pivotable cantilevered bracket assembly mounted on the base plate adjacent the holding fixture, a motor-driven rotary cutting blade disposed on the end of the cantilevered pivotally movable bracket assembly for movement along the surface of a printed circuit board disposed within the holding fixture, and an anti-warp device including one or more pivotable lever arms disposed above and below the printed circuit board, and an adjustable pin mounted on each of the upper lever arm to engage the top surface of said printed circuit board and urge the same into a flattened position and an adjustable pin disposed in each of the lower lever arms to engage the bottom surface of said printed circuit board to urge the same in a flattened position.

Abstract: A chute for feeding electronic components having axial wire leads into a machine for cutting and forming said leads includes spaced apart parallel plates defining therebetween a chamber for the bodies of the electronic components and has an elongated slot in each plate for receiving and guiding the axial wire leads thereof. The width of the slots and the distance between the plates are adjustable to accommodate components having varying body lengths and varying wire diameters. Wire retainers are also included to stop each component at the bottom of the chute and guide it into a position to be received and retained by the cutting and forming machine.

Abstract: An improved filter element for fluid circulating system having unpressurized reservoirs and primarily adapted for removing algae and other fine contaminants from swimming pool water comprising pleated filtration medium arranged in a cylindrical configuration having an open central area, a cap bonded to one end of the filtration medium to close the open central area, an adapter bonded to the opposite end of the filtration medium for connection to a flow source to direct the flow of water into the open central area for passage through the filtration medium in a direction from inside to outside and an outer support member disposed on the exterior of the filtration medium and closed at one end and secured at the other end to the adaptor to restrain the filtration medium.

Abstract: A manually operable collator is provided for assembling multiple paper sheets in sequential order, comprising a housing, having a plurality of paper receiving trays and reciprocally movable means for simultaneously transporting the top sheet of paper in each tray from the housing, including a plurality of pusher arms extending into each of said trays and adapted to engage said top sheets of paper. A paper guide is pivotally mounted on the front of the housing below the paper receiving trays and is adapted to guide the paper sheets transported from the trays to facilitate the gathering of such sheets. In addition, means are provided, linking the pusher arms and the pivotal paper guide, to lift the pusher arms out of engagement with the paper in each tray upon the downward pivotal movement of said paper guide to permit the loading of paper into said trays.

Abstract: An apparatus is provided for automatically loading a plurality of cassettes of the type having two rotatable spools and a leader tape connecting said spools with a predetermined length of magnetic tape or the like from a supply reel. The apparatus includes a magazine for storing a plurality of empty cassettes, means for advancing said cassettes, one at a time, from the magazine to a loading station, means for withdrawing the leader from the cassette, cutting it into two sections, and splicing the free end of one section to the leading end of a length of supply tape, means for automatically rotating one of the spools of said cassette to wind the spliced leader section and a predetermined length of said supply tape into said cassette, and means for cutting the supply tape after said predetermined amount has been wound into the cassette and splicing the trailing end thereof to the free end of the other leader section.
