ABSTRACT:
A truck or automobile thermometer for mounting on the exterior of the vehicle and subject to outside weather conditions is shown. The sensing element of the thermometer is of the usual rod type with a capillary tube containing mercury, etc. A direct reading dial with a pointer is operatively associated with the rod and is disposed at right angles thereto. An externally threaded nipple is connected with the thermometer and is coaxially disposed on the rod element. An internally threaded tube surrounds the rod and is spaced therefrom to provide an air chamber around the rod-sensing element. This tube has an end opening to admit exterior air and side outlet means to exhaust air. A bracket having two legs, disposed at right angles to each other, is provided with a hole in one leg of smaller diameter than the threaded tube. Then such hole is passed over the threaded nipple and the tube is threadedly connected with the nipple, thus uniting the rod, bracket, and tube. Then the bracket has its other leg connected with an exterior surface of the automobile cab or body, as the bracket normally mounting an outside rearview mirror, so the direct reading dial of the thermometer is in the line of vision often used by the automobile operator.
