A support for a reciprocating ram wherein a plurality of rollers having angularly related generally cylindrical support surfaces are mounted in a fixed location and the ram is provided with planar surfaces having the same corresponding angular relationship wherein the weight of the ram is utilized to maintain the planar surfaces in contact with the generally cylindrical support surfaces during reciprocal movement of the ram with dampening means being provided to minimize vibrations. An additional force is applied to the ram to ensure a rolling relationship between the planar and generally cylindrical surfaces at all times during the reciprocal movement.

Apparatus for supporting a body for reciprocal movement

A lightweight metallic container is disclosed and claimed having a side wall and an effective rigid bottom wall integral therewith. The side wall and bottom wall merge to define a first inclined face, the inclined face forming an angle of between about 35.degree. and 45.degree. with respect to the axis of said container, a tapered member is provided and is integrally formed at the juncture of the side wall and inclined face, the member having a taper angle in a given range and a given wall taper thickness, an annular surface integrally connected to the first inclined wall for supporting the container, a second inclined face integrally connected to the annular surface, and a curved panel integrally connected with the second inclined face. The curved panel is so formed that it has a radius of curvature greater than the diameter of the annular surface. The height of the second inclined face is less than half the height of the first inclined face. The metallic container as so defined has an improved bottom configuration that provides for substantial column strength as well as internal pressure stability. One important feature of the subject bottom configuration is the reduced amount of metal used to manufacture the container.
