Abstract

The rule of thickners which increases along its length allows the gap of a motor vehicle spark plug to be adjusted. The rule has a thickness which varies from a min. to a max. along its length and is made of hard metal. To adjust a gap, it is slid by force into the gap to open it. The required gap is obtd. by sliding it until the required graduation mark is reached. A circular rule is formed by a cylindrical assembly whose walls vary in thickness as required. A base ensures the rigidity of this assembly.

Description

La présente invention concerne les dispositifs permettant de mesurer et de régler l'écartement de deux parties drun ensemble déformable de façon permanente
Dans les dispositifs connus de ce genre on peut mesurer l'écartement à l'aide de cales dont on connait l'épaisseur et il faut ensuite modifier cet écartement pour arriver après plusieurs tentatives a un résultat a peu près satisfaisant.The present invention relates to devices for measuring and adjusting the spacing of two parts of a permanently deformable assembly
In known devices of this kind, it is possible to measure the spacing using spacers of which the thickness is known and it is then necessary to modify this spacing to arrive after several attempts at an almost satisfactory result.

Le dispositif objet de l'invention comporte en figure i, une régle I de largeur convenable et d'épaisseur variant d'un minimum 2 à un maximum 3 et présentant des graduations d'épaisseurs intermédiaires.The device which is the subject of the invention comprises, in FIG. I, a rule I of suitable width and thickness varying from a minimum of 2 to a maximum of 3 and having graduations of intermediate thicknesses.

Pour régler l'écartement des deux parties de l'ensemble 4 il suffit de faire glisser, en forçant, la régle 1 jusqu'a la graduation désirée.To adjust the spacing of the two parts of the assembly 4, it suffices to slide, by forcing, the rule 1 until the desired graduation.

La régie graduée peut oestre droite, figure I ou courbe figure 2.The graduated control room can be straight, figure I or curve figure 2.

Les figures 3 et 4 illustrent, à titre d'exemple, un mode de réalisation du dispositif conforme à l'invention.Figures 3 and 4 illustrate, by way of example, an embodiment of the device according to the invention.

Tel qu'il est représenté, le dispositif comporte pour l'essentiel deux régies courbes accolées formant un anneau circulaire dont les circonférences extérieure 5 et intérieure 6 sont excentrées de façon a obtenir une épaisseur minimum 2 et une épaisseur maximum 3.As shown, the device essentially comprises two adjoining curved boards forming a circular ring whose outer 5 and inner 6 circumferences are offset so as to obtain a minimum thickness 2 and a maximum thickness 3.

Un fond 7 assure la rigidité de l'anneau et facilite la lecture des graduations d'épaisseur.A bottom 7 ensures the rigidity of the ring and facilitates the reading of the thickness graduations.

Le dispositif, objet de l'invention, a une application particulièrement intéressant pour le réglage très précis de l'écartement des électrodes des bougies d'allumage utilisées sur les moteurs d'automobiles. The device, object of the invention, has a particularly advantageous application for very precise adjustment of the spacing of the electrodes of the spark plugs used on automobile engines.
