Apparatus for securing a wheel onto a shaft or the like

Abstract

Abstract 1. AN ASSEMBLY COMPRISING: A. A SPINDLE HAVING ITS OUTER SURFACE THREADED ALONG AT LEAST A PORTION OF ITS LENGTH, SAID SPINDLE HAVING AN END PROVIDED WITH A PLURALITY OF RADIALLY EXTENDING DEPRESSIONS OF EQUAL ARCUATE CROSS-SECTION, ADJACENT ONES OF SAID DEPRESSIONS BEING EQUALLY ANGULARLY SPACED FROM ONE ANOTHER, THE AXES OF SAID DEPRESSIONS FALING INTO A SINGLE PLANE TO WHICH THE AXISOF SAID SPINDLE IS PERPENDICULAR, B. A WHEEL, SAID WHEEL HAVING A CONCENTRIC AXIAL BORE OF AN INNER DIAMETER SLIGHTLY LARGER THAN THE OUTER DIAMETER OF SAID SPINDLE SUCH THAT SAID WHEEL MAY BE SLIPPED ONTO SAID SPINDLE WITH A PREDETERMINED MAXIMUM OF RADIAL PLAY THEREBETWEEN, SAID WHEEL BEING PROVIDED WITH A PLURALITY OF DOWELL PINS EXTENDING RADIALLY INWARDLY INTO SAID BORE, SAID PLURALITY OF DOWEL PINS CORRESPONDING IN NUMBER AND ANGULAR DISPOSITION TO SAID PLURALITY OF DEPRESSIONS AND HAVING EQUAL RADII AT LEAST AS LARGE AS THE RADII OF CURVATURE OF SAID PLURALITY OF DEPRESSIONS, THE AXES OF SAID DOWEL PINS FALLING INTO A SINGLE PLANE TO WHICH THE AXIS OF SAID WHEEL IS PERPENDICULAR, ND C. A NUT PLATE HAVING A CONCENNTRIC AXIAL BORE THREADED AND DIMENSIONED FOR THREADED ENGAGEMENT WITH SAID SPINDLE AND A PLURALITY OF BOLT RECEIVING, THREADED AXIAL BORES DISPOSED RADIALLY OUTWARDLY FROM AND EQUALLY CIRCUMFERENTIALLY SPACED ABOUT SAID CONCENTRIC AXIAL BORE THROUGH SAID NUT PLATE, SUCH THAT SAID DOWEL PINS SEAT INTO SAID DEPRESSIONS TO PREVENT RELATIVE CIRCUMFERENTIAL MOVEMENT BETWEEN SAID SPINDLE AND SAID WHEEL, D. SAID WHEEL BEING PROVIDED WITH A PLURALITY OF APERTURES DISPOSED FOR AXIAL ALIGNMENT WITH SAID BOLT RECEIVING THREADED BORES IN SAID NUT PLATE WHEN SAID NUT PLATE IS THREADED ONTO AND SAID WHEEL IS SLIPPED ONTO SAID SPINDLE, AND E. A PLURALITY OF BOLTS EXTENDING THROUGH SAID APERTURES AND THREADED INTO SAID BOLT RECEIVING BORES. D R A W I N G
