Abstract
Exothermic welding apparatus includes a toggle frame jig for supporting vertically split molds. The toggle includes a post projecting parallel to the main pivot of the jig on which telescopes a crucible support. The crucible support includes a handle extending above the crucible when secured to the support. A quick acting toggle connects the support and post enabling the crucible to be assembled, cleaned, or prepared remote from the molds and then quickly installed and locked in position.
Claims21
Exothermic welding apparatus having a toggle frame comprising respective frame members for holding separable mold parts for opening and closing said members being interconnected at a hinge pivot, means on said members releasably holding a mold part, a post extending from one of said members parallel to the axis of the hinge pivot, a crucible support mounted on said post for movement therealong, means on said crucible support releasably holding a crucible, and means to urge said crucible support and thus said crucible toward the mold parts.
Exothermic welding apparatus comprising first means for opening and closing two mold parts on a vertical parting plane, second means mounted on said first means for supporting a crucible for movement toward and away from said mold parts, and in alignment with said mold parts when closed.
