601c CHAPMAN, T., and ALDERMAN J., 8 Denmark St., Soho — Inventors and Manufacturers.
General invalid couch, which is capable, by mechanism, of being changed into any required position, without disturbing the patient; the change of position being so gradual that it is almost imperceptible.
It will form an easy chair, with arms, which adjust themselves without trouble, or can be taken off if required, without unscrewing.
It is also suitable for surgical cases, as every variety of position can be obtained. When converted into a level couch, the moveable scroll end at the head may be turned into a writing table and reading desk, so that a patient, while reclining, may read and write with comfort.
The mattress is elastic, resting upon an elastic-adjusting foundation, by which all pressure can be taken off from any part of the patient, in cases of long illness.
The following cut represents the couch.
