    Wouldn't that be the reverse door swing of #2? See updated file: Crane Hinge Configurations.pdf

    Does anyone know what the rectangular slot is for on the Capital Grille's pressure system cam?

    Does anyone know how the vertical 'roller bearing racks' inside the remote combination viewer work with the pressure system lug? I assume the lug crawls up the racks as pressure is applied but not sure how they hold the lug in place. This is from the Capital Grille vault door in NYC.

    My own guess on this is that the rollers are simply acting as a linear bearing as the lug block moves up and down under considerable side-load pressure. I don't think it is a "rack" (in the sense of rack and pinion) at all.

    The slot's finish looks as-cast rather than machined, so it would be lacking any sort of precision in terms of location or shape. Maybe an engineer saw a chance to conserve material and reduce weight (presumably without impacting strength). Or a place to grip it while wrestling the door open.

    What wylk said- the sideways forces are immense- without the linear races the floating block would seize solid against the inside wall of the RCV housing.
    Whatever force the pressure system is capable of is transferred through the components as well as the equal opposing forces pushing/pulling on the RCV. It’s amazing the difference a rolling effect has in spreading the load while reducing friction, eliminating dig-ins, and minimising wear on the mating surfaces.
