Abstract: ABSTRACT OF THE DISCLOSURE             A device for gripping or locking a rope or wire comprises a pair of rope engaging members or jaw members defining a pair of oppositely arranged wire engaging surfaces forming a passageway for the rope. The jaw members are mounted in the frame of the gripping device by means of a swinging link suspension including a pair of swinging links.  The jaw members are suspended so that the frictional forces acting between the rope and the jaw members cause displacement of the rope engaging surfaces thereon in mutual parallel relationship towards each other, when a pulling force is applied to the rope in a first direction, while the rope engaging surfaces are displaced away from each other, when a pulling force is applied to the rope or wire in a second opposite direction.  This means that the rope is pinched between the rope engaging surfaces, when the rope is pulled in the said first direction, and released, when pulled in said second direction.  The jaw members may comprise a first jaw member having a U-shaped cross-section with an inner bottom surface defining a first rope engaging surface, and a second jaw member displaceably received within the first jaw member.  Corresponding swinging links suspending said first and second jaw members may be mounted pivotally about a common axis and define an angle therebetween, and these swinging members are preferably formed as an integral part. The jaw members may be moved to a rope releasing position by means of an operating handle.

Abstract: ABSTRACT OF THE DISCLOSURE        An infant care center that includes a standing, vertical frame and has an infant bed that is suspended outwardly from the vertical frame.  The infant bed is adapted to retain the infant and is readily adjustable to a plurality of positions devised for the infant.  The bed itself is tiltable about an axis to the various positions and a unique tilt mechanism allows the degree of tilt to be easily selected and then locked into position by attending personnel.  The tilt mechanism includes a double acting piston assembly that secures the frame to a point on the infant bed remote from the axis about which the bed is tiltable.  The double acting piston assembly includes a piston operable within a cylinder and which divides the cylinder into two variable chambers.  Each chamber has a part to introduce and remove hydraulic fluid therefrom and a closed circuit joins the parts so that fluid normally can move from one chamber to the other or the piston travels within the cylinder to move the tilt position of the infant bid.  A valve is conveniently located for such personnel to open or close the closed circuit to the flow of hydraulic fluid such that when the valve is open, the infant bed may be moved to the desired position and the valve then closed to prevent further movement of the piston and therefore the infant bed is locked into that desired position.
