ABSTRACT:
Within a closing assembly that utilizes a ram assembly having a spring driven ram body, an energy dissipating spring seat assembly is provided. The ram body is mounted on a guide assembly having at least one pin. The guide assembly also includes a base plate and a stop plate. A ram assembly spring is disposed between the ram body and the base plate and is structured to bias the ram body toward the stop plate. The spring seat assembly includes a spring seat bracket and a spring seat. The spring seat is, preferably, a generally flat, plate-like leaf spring that is disposed between the ram assembly springs and the base plate of the ram body. The spring seat is sufficiently rigid so as to not deflect fully under the force created by the compressed ram assembly springs, but not so rigid as to resist deflecting under the force created when the ram body impacts the stop plate.
