CRUSHER SWING JAW ABSTRACT OF THE DISCLOSURE Plates, of steel or other suitable material and which are appropriately sized, are welded together to form a fabricated swing jaw body for a jaw type crusher. The barrel, disposed proximate the upper extremity of the swing jaw body and which houses the bearings and shaft that operate the swing jaw, is formed either: from a continuous plate rolled into a cylinder of proper size and welded into the swing jaw body; from a number of plates welded to each other and to the swing jaw body to form therewith a cylinder like enclosure for said bearings and shaft; or from a number of plates with openings formed therethrough and stacked and welded on against the other and to said swing jaw body to form said enclosure. A piece of non-rectangular bar stock is secured proximate the bottom of the swing jaw body and has formed therein a seat for the toggle plate mechanism of the crusher jaw. Various cross bracings are welded within, outside, or within and outside said steel plates to secure and strengthen same; while a backing plate or backing strips are also welded thereto to provide additional strength and securing means.
