A gage for measuring a force at which hooks of couplers used to couple passenger transit type vehicles together are biased when such vehicles are coupled together by such hooks. Such gage including a bracket member having at least one guide pin disposed thereon. Such at least one guide pin being sized and located to seat in at least one guide hole disposed in a railway transit coupler. An elongated tubular housing member is mounted on such bracket member. There is a main coil spring disposed within such elongated tubular housing member. A shaft member is disposed along a longitudinal axis of such main coil spring. A plunger member extends from a forward end of the shaft member and such tubular housing member for engaging a hook portion of such coupler and a power screw member is threadedly engaged into an end of the elongated tubular housing member opposite the forward end of such tubular housing member for translating the shaft member in such elongated tubular housing member and such plunger member into and from such hook of such coupler.

Appareil de mesure conçu pour mesurer la force à partir de laquelle des crochets d'attelage servant à atteler les uns aux autres des véhicules de transport en commun subissent une déformation lorsqu'on les utilise. Cet appareil de mesure présente une patte comportant au moins un axe de guidage, lequel est conçu de telle sorte que sa taille et sa disposition lui permettent d'occuper au moins un trou de guidage de l'attelage du véhicule. Un logement tubulaire allongé est installé sur la patte, et un ressort hélicoïdal principal se trouve dans le logement. Un arbre est également disposé le long d'un axe longitudinal de ce ressort hélicoïdal principal, et un poussoir va de l'extrémité avant de cet arbre au logement tubulaire pour s'engager avec le crochet de l'attelage. Enfin, une vis de puissance s'engage dans un filetage, au niveau d'une extrémité du logement tubulaire allongé, du côté opposé de l'extrémité avant du logement tubulaire allongé, pour déplacer l'arbre par translation dans le logement tubulaire et pour insérer le poussoir dans le crochet de l'attelage.
