Abstract: A self-aligning, pivotally engaging container sealing device is provided. The device comprises a base, a sealing head including an upper die member pivotally mounted relative to the base, and a lower die member supported by the base for free pivotal and vertical movement relative thereto. The lower die member is biased generally upwardly by a spring or other biasing mechanism, while permitted to tilt substantially freely about a generally horizontal axis. The device may be manually actuated by pivotally lowering the sealing head to operatively engage the die members. Initial contact by the descending upper die member on a part of the lower die member impels the lower die member to tilt into parallel alignment with the upper die member, before any significant force from the biasing member is transmitted through the lower die member to the upper die member to clamp and form a seal between a container flange and container cover located between the upper and lower die members.

Abstract: A transportable machine reduces vehicle tires to a fine powder size suitable for incorporation into new articles of manufacture. An upper infeed assembly is mounted to a frame above a spring-loaded upwardly biased lower infeed assembly. A splayed tire is fed between guiderails on the upper and lower guide assembles and is driven along by upper drive sprockets and rides on lower idler sprockets. The tire is fed by a tire-feed positioned above a cutter bar and biased downwardly to clamp a cut splayed tire against the cutter bar and to feed the tire over the bar and into cutter blades mounted on a rotary blade assembly. The rotary blade assembly has a shaft mounted for rotation about an axis to the frame and has a plurality of cutter blades spaced about the shaft periphery. Each rotary cutter blade has a saw-toothed profile with triangular teeth. The tips or the moving blades are slightly spaced from the cutting edge formed on the fixed cutter bar.
