Abstract
A mechanism providing both a brake and tie-down mechanism for a cart which utilizes a central support below the bottom of the cart for supporting both the vertically moving brake shoes and the rotating locks of the tie-down mechanism, and foot pedals at opposite ends of the cart for engaging and disengaging the brake shoes with the supporting surface and for rotating the locks to release the cart from the tie-down mechanism, the tie-down mechanism being arranged to receive a tie-down mushroom from either end of the cart.

A brake and tie-down mechanism for a cart movable on a support surface comprising:
- separate support means secured to the bottom of said cart and spaced apart transversely of said cart;
- a tie-down mechanism comprising a pair of tie-down locks pivotally mounted at opposite ends on said support means and spaced apart longitudinally of said cart to form a tie down space therebetween;
- said space receiving and retaining a tie-down mushroom rigidly secured to said surface in order to restrain the movement of said cart;
- brake means mounted on each of said support means comprising brake shoes selectively movable into engagements with said support surface to brake the movement of said cart;
- first lever means for moving said brake shoes into engagement with said surface;
- second lever means independent of said first lever means for moving said brake shoes away from said surface and simultaneously releasing said mushroom from said tie-down locks;
- said second lever means comprising two separate linkages, each linkage being actuated from a different end of said cart to pivot a different one of said locks to release said mushroom, said brake shoes being moved away from said surface by actuation of either of said linkages to move one of said locks;
- said first lever means being actuated from either end of said cart for moving said brake shoes into engaging position.

- first lever means for moving said brake shoes into engagement with said surface;
- second lever means for moving said brake shoes away from said surface and releasing said mushroom from said tie-down locks;
- said brake means comprising a pair of brake arms pivotally connected to each said support means, one of said brake shoes being connected to one end of each brake arm;
- an overcenter mechanism connected between the other ends of each pair of brake arms;
- said first lever means moving said overcenter mechanism into position to engage said brake shoes with said surface;
- said second lever means moving said overcenter mechanism into position to hold said brake shoes away from said surface in non-engaging position.
