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: Apparatus for dampening the closing of a heavy door of the type mounted along a hinge axis on a heavy movable member such as a digging bucket for a shovel, said dampening apparatus comprises a crank pivotally mounted intermediate its ends on said movable member adjacent said hinge axis, linkage means pivotally mounted adjacent one end thereof on said door and pivotally connected adjacent an opposite end to one end of the crank, a cushioning device having a lower pivotal connection pivotally connected to the crank at the end thereof opposite from the first-mentioned end and an upper pivotal connection pivotally connecting the cushioning device to the movable member, and the cushioning device comprises a telescopic rubber snubber.
