This protractor was donated to the collection by an aircraft mechanic who worked for Spartan Air Services from 1952 to 1983. The donor found this protractor in his office upon his retirement. It was used at Spartan Air Services in the machine shop shop built specifically to service the company’s fleet of helicopters. Ce rapporteur biseauté est parvenu à la collection grâce à un mécanicien d'avion qui travaillait pour les Services de transport Aérien Spartan (Spartan Air Services) entre 1952 et 1983 respectivement. Le donateur a trouvé le rapporteur biseauté dans son bureau quand il a pris sa retraite. L'objet était utilisé à la compagnie ou le donateur travaillait à l’atelier d’usinage pour l’entretien de la flotte d’hélicoptères de Spartan Air Services.
Function
In aircraft maintenance, the tool is used as part of a bevel protractor to establish and test angles to close tolerances (ie: having two pieces that fit well together but between which a gap must be maintained, even when the pieces expand due to an increase in temperature). Cet objet est utilisé pour avec un rapporteur oblique pour l'entretien des aéronefs pour établir et tester des angles des tolérances serrées (quand deux morceaux s'accordent bien, mais ils doivent maintenir un espace entre eux malgré le fait qu'ils peuvent agrandir grâce à une augmentation de température).
Technical
Bevel protractors have a long history of use in occupations requiring precision measurement, in particular, drafting and engineering. This instrument is used primarily for angular measurements. This metal instrument consists of a circular protractor housed within an irregularly shaped blade. An 11-1/2” or 5-1/2” trapezoidal blade slides into the housing. A screw on the protractor fixes that blade in place. The protractor is divided by single degrees and marked by tens from 0° to 90° to 0° to 90° to 0°. A Vernier (a smaller scale) is attached by another screw and permits angle readings to five minutes of accuracy. Les rapporteurs biseautés sont utilisés fréquemment quand des mesurages précis sont de nécessité comme les desseins techniques et les desseins industriels. Cet instrument est utilisé principalement pour des mesures angulaires. L'instrument consiste d'un rapporteur circulaire tenu à l'intérieur d’une lame en forme irrégulière. Une lame en forme trapézoïdal qui est soit 11 pouces et demi ou cinq pouces et demi glisse à l'intérieur de l'objet. Une vis sur le rapporteur fixe la lame en place. Le rapporteur est divisé par dégrées simple et ils portent des marques qui augmentent en séries de dix dégrées à la fois en commençant à 0° jusqu'à 90° et de retour jusqu'à 0°. L'échelle répète en alternant un total de quatre fois entre les deux séries d'angles. Une échelle à vernier est attachée avec une autre vis qui permet la lecture des angles à une précision de cinq minutes.
