Though making of thermometer is a very old and long established art, significant developments in this field have been few and far between, particularly in recent years. Most of the research in this industry has been concerned with visualappearance since this is a feature that more times than not will induce a purchase. In this last respect outdoor thermometers have had particular attention but while they have been produced in many interesting forms and with minor improvements in theirmode of support and housing, it seems that little attention has been paid to their accuracy. The accuracy of those reasonably priced units which reach the average purchaser leaves much to be desired and it is oftentimes the nature and characteristic ofa thermometer support or housing that contributes to inaccuracies in their readings.

Preferred embodiments of the invention have particular utility for use outdoors and for mount on the hood of a moving vehicle. The invention construction provides for a thermometer to be housed so that only its sheltered sensing bulb is exposedto the ambient air through which the vehicle moves. The bulb is contained in a manner that is essentially shielded from the disruptive temperature influence of direct rays of the sun or reflectors. The housing is designed to expose to the driver of thevehicle on which the thermometer unit is mounted only that portion thereof from which a reading may be taken. A feature of the mount of the thermometer is that it may be rotated within its housing so as to enable it to be presented in the best possibleposition for viewing from the interior of the vehicle to which it is applied.

In their many years of experience in the art with which the invention is concerned, the inventor and his associates have obtained no knowledge of any prior art which is particularly pertinent to the essential features for the present invention.

An additional object of the invention is to provide a thermometer so housed as to indirectly expose its bulb portion to ambient air while the remainder thereof is nested in and protected by means adapted to reflect impacting rays, preventing therays from exerting disruptive influences on the thermometer, thereby to affect its readings.

A further object of the invention is to provide an economical thermometer unit, particularly suited for safe outdoor usage which possesses the advantageous structural features, the inherent meritorious characteristics and the means and mode ofuse herein described.

The features described all contribute to the desired end result, the achievement of a highly accurate inexpensive thermometer especially advantageous for outdoor usage. Of no less value is the nature and form of construction of the thermometerwhich enables its economical manufacture and embodies the fature which permits a ready rotation of the thermometer in place. Moreover, the sheltered and recessed mount of the thermometer substantially eliminates chance of breakage.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification inits form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the meansand construction herein disclosed comprise but one of several modes of putting the invention into effect and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
