Open the CIPO recordAbstract From the Canadian patent
In a draft gear apparatus, the housing is strengthened to better withstand distortion by draft stress imposed by the yoke on the end of the housing. Strengthening is accomplished by increasing the thickness of the housing side walls at selected areas near the housing end and by widening and thickening portions of the ribs which partially define the main spring chamber.
