Abstract: A high precision height comparator and surface gauging apparatus utilizing a novel micro-adjuster securable to the carriage of a transfer stand and having a clamp for securing a test indicator thereto. The micro-adjuster is a self-contained unit clampable to the carriage of a transfer stand and is provided with a high resolution differential screw. A simple rugged clamp mounted on the micro-adjuster accommodates any suitable test indicator of either the electronic or mechanical type. When used with an electronic indicator, comparative measurements are routinely made to an accuracy of a few millionths of an inch.

Abstract: Caliper with a pistol grip and a simple two-piece clamp for releasably securing a dovetail-equipped dial indicator thereto. The caliper fingers are stabilized and strengthened along their midlength by bracket plates fixed to the sides of one finger and embracing the sides of the other finger.

Abstract: A knock-down invalid bed having a main frame supported at its ends by head boards and separable into two halves at its mid-length. Attached to each half are pivoting sections of a pair of tubular mattress-supporting subframes adjustable to support a patient horizontally and in different angular positions. The subframes support two link fabric units separably interconnected crosswise of the mid-length of the bed. Attached to the head board and overlying one end of the bed is a patient helper device to aid the patient in shifting his position in bed, and other useful functions.
