Abstract
Abstract This clamp comprises a cylindrical shank on which is a slidable and rotatable sleeve. A lower clamp foot is secured to one end of the shank and an upper clamp foot is secured to the sleeve. The two clamp feet can be clamped onto a support which forms part of the side of the bed by a nut which is threaded onto the shank. A socket in the upper end of the shank is adapted to support a removable upright member used in connection with the bed.

The combination with a bed having an upright flange extending along the edge thereof, of a clamp comprising a shank having an externally threaded upper end portion; a socket in the upper end portion of said shank adapted to receive a member to be supported; a hook-shaped lower shank foot rigid with the lower end portion of said shank and extending sidewise and upwardly relative to said shank; a sleeve rotatable and slidably movable longitudinally on said shank; an upper clamp foot rigid with and protruding transversely from the upper end portion of said sleeve; a nut on the threaded upper end Portion of said shank adapted to engage with the upper end portion of said sleeve and clamp said two clamp feet onto the upright flange at the edge of the bed; a compression spring interposed between the lower end of said sleeve and the lower clamp foot, said spring yieldingly and frictionally urging said sleeve against said nut, whereby when the clamp is detached from the flange maximum separation of said two clamp feet is maintained and undesirable rotary movement of the sleeve and upper clamp foot on the shank is minimized.
