ABSTRACT OF THE DISCLOSURE: An adjustable frame, applied to a bed, supports selectively rotatabie rolls at the level of the bed mattress in parallel and close relation thereto. The rolls are connected to an electric motor via driving chains around the underside of the bed. A draw sheet extends between the rolls across the upper side of the bed and is wound on both rolls with the patient on the draw sheet. A control box operating on low voltage (e.g. 24 V) current enables the patient or a nurse to turn on the electric motor to rotate in one direction or the other. Each roller is provided with an automatic driving and free wheel clutch providing for driving of each roll only in one direction, namely the direction of reeling, so that when the one roll is being driven the other is freely rotating and vice versa. Furthermore, each driving and free wheel clutch unit can be manually connected and disconnected by use of an external eccentric.
