Abstract: A vending machine with an anti-condensation product viewing window. The product viewing window has two window sections. The first window section is typically a wall or portion of a wall of the product storage chamber. A second window section is spaced outwardly a distance from the first window section to form the face of the viewing window. An illumination device is placed between the first and second window section. The heat from the illumination device prevents a build up of condensation on the window sections. Substantially sealing the two window sections further reduces the condensation build up. One or more small openings in the sealings between the two window sections into a cooler area allow for the escape of any moisture which does accumulate between the two window sections. The illumination device can also be used to illuminate the products to be vended, back light a sign on the machine or both.

Abstract: A vending machine with an improved sealing holding bin drawer for removing dispensed products. Products are dispensed from a housing chamber which is maintained at a temperature colder than the environment in which the vending machine operates into a holding bin. The holding bin has a first opening allowing the products from the housing chamber to enter. The holding bin has a second opening covered by a door allowing the user to remove dispensed products from the holding bin. A sealing hood selectively covers and seals the first opening between the holding bin and housing chamber. The door and the sealing hood are operably connected such that the sealing hood covers the first hole when the door is opened. The connection is accomplished utilizing a pin and cam slot arrangement. The holding bin can also have an attached storage bin and can be placed on rollers such that it slides out of the vending machine like a drawer.

Abstract: Articles such as cans vertically stacked on a serpentine shelf (30) and on a longitudinally inclined shelf (33) at the lower end thereof are dispensed one at a time by a motor driven article release mechanism (24). A single can is dispensed for each user actuation of the release mechanism (24). A pair of longitudinally and arcuately spaced fingers (72), (73) are mounted for rotation as a unit as a part of the mechanism (24), and extend at right angles to the longitudinal axis of the cans in the section. The lowermost finger (72) is normally in can-blocking position and the upper finger (73) is normally in a non-can-blocking position. Upon actuation of the mechanism, the fingers are rotated sequentially from their normal positions to a second position, where a lowermost can (C') is released and the next adjacent can (C") held in place, to their normal positions where the next adjacent can (C") moves by gravity down against the lowermost finger (72).

Abstract: A vending machine has a frame comprising a newspaper holding compartment with a spring hinged door and a housing for a mechanical control system secured to the top of the holding compartment. A vending member is secured to the door and operably engaged with the control mechanism. The control mechanism includes a lever biased to a locking position with respect to the vending member. A lever holding rod is secured to the lever and has an "up", or unlocked, position wherein the lever does not lock the vending member, and a "down", or locked, position wherein the vending member is locked in position. A coin operated mechanism has an output shaft and cam which rotate in response to the insertion of a low price coinage amount to a first position, and a high price coinage amount to a second position. A second cam is mounted for free rotation on the coin mechanism shaft and is gravity biased to follow the first cam.

Abstract: A mechanism for selectively locking and releasing an actuating device for a vending machine. The actuating device, when unlocked and actuated, releases an item from the vending machine. The locking and releasing mechanism of the invention includes a shaft rotatably connected to the actuating device. A pair of arm members are attached to the shaft, one being rigidly attached and the other being rotatably attached with respect thereto. Springs are provided for biasing the arm members to a first position for locking the actuating device against an abutment surface connected to a frame member. A cam structure associated with the actuating device is provided for rotating the shaft to thereby unlock one of the arm members under certain circumstances. A projection of a coin registering mechanism is provided to cause unlocking of one or both of the arm members when a predetermined amount of money is registered on the coin registering mechanism.

Abstract: A vending apparatus of a type utilizing a selectively rotatable helical member. The helical member is connected at one end to an annular plate having gear teeth around the inner periphery thereof. A drive gear is disposed within the annular plate and is in operative engagement with the teeth on the inner periphery of the annular plate. The drive gear and thereby the annular plate and helix is driven ultimately by an electric motor. Once the motor is turned on the helical member will rotate one-half of a revolution before being switched off by a switching device. A vertical divider is disposed within the helical member and supports the helical member along the top thereof. A portion of the helical member is aligned along the longitudinal axis of the helix and this portion is connected to the vertical divider for stabilizing and supporting the helical member as it rotates. A plurality of such vending units are stacked on top of one another and are slidable into and out from a cabinet housing.

Abstract: A vending apparatus of the type having a helical member rotatably disposed in a vending chamber. A vertical divider is disposed within the helical member for positioning items to be vended in two rows. A mechanism is also provided for compressing the helical member and releasing such compressed helical member by rotation of such helical member to thereby aid in the discharge of items placed on one side of the vertical divider. Rotation of the helical member by one-half of a revolution releases an item on one side of the vertical divider. Further rotation of one half of a revolution releases an item from the other side of the vertical divider, and so forth, releasing an item from the front of each side successively.
