Abstract: A method for mounting a large tire onto a single-piece rim comprising the steps of first securing the rim to a stand having an upwardly extending ram, positioning an oblique cone atop the rim with the ram extending through its center, the majority of the cone is open except for three spaced and sloped segments wherein one segment is more steeply sloped than the two remaining segments, placing the tire on the cone, positioning a presshead having a downwardly extending post and three radially spaced hydraulic cylinder arms above the stand wherein the arms are pivotally mounted on the presshead and extend downwardly therefrom, a first arm having a horizontally disposed foot mounted on its lower end is aligned with the steeper segment, the two remaining arms each having a foot are aligned with the remaining segments respectively, lowering the presshead thereby receiving the ram within the post and having the feet resting upon the upper sidewall of the tire, extending the first foot against a first portion of the

Abstract: A vent accumulator for a hydraulic integrator of the type having at least three pistons arranged in end-to-end relationship within an elongated housing. Each piston is adapted to move under hydraulic pressure in a direction away from one longitudinal end of the housing towards the opposite longitudinal end. Each of the pistons, except for the last piston adjacent the opposite end of the housing, is provided with a piston rod operatively connected to the piston next adjacent towards one end of the housing. Each piston is defined as having a first side directed towards one end of the housing and a second side directed towards the opposite end of the housing. Each of the pistons, except for the last two pistons in line, is provided with means for receiving hydraulic fluid under pressure from a load cell on its first side and an air vent communicates on it second side.
