Abstract: A bead seating system which comprises a wheel and tire support having a small diameter central hub, a plurality of widely spaced radial clamp carrying support arms, a single, elongated air nozzle located below and in proximity to the support and a noise reduction housing enclosing the nozzle. The orifice of the nozzle is elongate in the horizontal direction and directs a flat, trapezoidal stream of air through an opening in the noise reduction housing and the space between two of the radial support arms into the area between the bead of the tire and the rim of a wheel resting on the support. The nozzle is angularly oriented relative to the horizontal so that for all rim sizes the air stream is directed either into the space between the rim and the bead or in a direction nearly tangential to the outer wall of the tire. Accordingly, the air flows along the side wall of the tire in a laminar manner into the tire.

Abstract: A surface blasting apparatus for treating a surface with abrasive, cleaning dust and debris from abrasive rebounded from the treated surface so that the abrasive may be reused, and separating the debris from the air. Air and debris flow through abrasive rebounded from said surface and through a baffle system which prevents abrasive flow therethrough. A row of magnets is positioned adjacent the baffle system for receiving and arresting abrasive exiting an abrasive return chute. A mechanical conveying system lifts abrasive upwardly so that it falls toward an abrasive storage hopper. The abrasive falls in the form of a curtain through which air exiting the baffle system passes. The air and dust contained therein enter a prefilter in a first cleaning chamber and heavy dust falls downwardly therefrom. The air flows from the prefilter into a second cleaning chamber where it is filtered so that light dust is removed therefrom and falls downwardly.

Abstract: A hand tool for transmitting torque having a handle wherein a tool implement blade may be alternately mounted in three positions on the handle. A slot defined at one end of the handle permits the implement having a shaped head fixed thereon to be mounted such that the implement axis is parallel or transversely related to the handle axis, and a recess formed in the handle central region receives the implement head to permit the tool to be centrally located on the handle and transverse thereto to permit "spinning" of the implement. A retainer rotatably mounted upon the handle prevents inadvertent release of the implement from the slot and a spring biased plunger prevents inadvertent release of the implement from the central recess.

Abstract: A wrench retaining clip mounts on the shank of a wrench and is operative to retain a working head of the wrench in an engaged position on a nut or bolt head of a threaded bolt. The clip includes a channel-shaped yoke which extends partially around the wrench shank. A prong member extends longitudinally from the yoke and has a free end adapted to engage the threads of the bolt, and the yoke is slideable on the wrench shank to move the prong into and out of this engaged position. A releaseable locking mechanism is formed by a pair of resilient arcuate arms extending from the yoke in a semi-circle. These arms may releaseably embrace the working head of the wrench to lock the yoke and prong into the engaged position with the prong being biased into thread engagement. A notch is preferably formed at the free end of the prong to mate with adjacent side surfaces of the nut or bolt head where thread engagement is difficult or impossible.
