  • Spindle mixer with interlock assembly
    Patent number: 7780338
    Abstract: The invention relates to an interlock assembly for a spindle mixer where the interlock assembly includes a cup guide, an actuator pin, and an interlock mechanism. Placing a cup within the cup guide actuates the actuator pin that, in turn, engages the interlock mechanism. Engagement of the interlock mechanism selectively activates an electric motor. The pin moves through the body of the guide. The guide can be selectively removed from the mixer, and the pin, in one embodiment, is selectively removed from the guide. An optional bypass switch can be included to allow for the direct engagement of the motor.

  • Device for adjusting head pressure in top side cooker
    Patent number: 5423253
    Abstract: A pressure adjustment mechanism for a top side cooker head includes an adjustable element secured to the top side cooker head arm. In one embodiment the element is adjustable in discrete one-half turn increments of a screw and in another embodiment is continuously adjustable. Both embodiments change the moment arm of a pneumatic cylinder ram that applies a counterbalance force to the cooker head. The invention permits adjustment of the force applied to foodstuffs on the griddle surface from 0 to the weight of the cooker head.
