Abstract: A jamming mechanism for a coin-operated vending machine has a first slide member movable between a normal checked position in which the vending machine is locked out of service and a coin-activated operative position in which the vending machine is placed in service. A second slide member engageable by a user of the vending machine is releasably interconnected by a breakable element to the first slide to prevent relative movement therebetween in the absence of predetermined force applied to the second slide to break the breakable element. The second slide can thus normally be used to control the movement of the first slide from the checked position to the operative position when the proper coins are inserted. If excessive force is applied, the breakable element breaks and a spring-loaded stop pin extends from the first slide to engage the body of coin mechanism to prevent movement of the first slide.

Abstract: This disclosure is directed to a coin slide assembly having a coin slide disposed for accommodating up to eight coins in a vertical position. The assembly further includes sets of inter-engaging channels and post on the assembly housing and on the coin slide, respectively, to restrict access to the internal blocking dog components of the assembly by persons intent on damaging or interferring with the normal operation of the dogs. A gate is provided through which the coins pass upon inserted movement of the coin slide. The assembly further includes a coin sizing block having inverted V-shaped notches which cooperate with the blocking dogs to render the coin slide operative only when properly sized coins are carried by the slide. A protective bar restricts the movement of the blocking dogs beyond their non-blocking position to prevent distortion of the spring which biases the dogs to their normal blocking position.

Abstract: A coin chute adapted to receive interchangeable coin slides. One type of slide may have one or more coin sockets fitted with one or more knock-out plugs to accommodate differently sized coins in each of the sockets. Another type of slide has either one, two, three or four open coin sockets of different sizes.The chute carries a blocking device with a plurality of sizing dogs biased against the coin slide. The sizing dogs are adapted to engage with the coin receiving sockets of the slide to jam continued projected movement of the slide in the absence of predetermined sized coins therein. The position of the dogs relative to the sockets of the slide and the spacing between the dogs is pre-set to similarly engage with differently sized socket openings of replacement slides without further adjustment of the sizing dogs to permit interchangeable use of coin slides whereby the coin chute is operable to accept a variety of differently sized coins and coin combinations by changing slides.
