Abstract: A water cooled gas metal arc welding (MIG) gun which is provided with a water cooling system for the gun barrel that introduces the coolant water at the bottom of the barrel to create a coolant water flow through the gun that does not allow the coolant water to stagnate and heat up. The gun includes a water cooled shielding gas cup on the lower end that ensures coolant water flow therethrough, and provides metal thickness at the end of the cup which prevents physical abuse of the cup from affecting the guns' performance. The gun has a shielding gas delivery system which ensures good shielding gas flow and allows for replaceable shielding gas diffusers.

The flexible collet may be used for single, or plural workpiece gripping actions. The collet includes a spring steel body having a radial opening and an outer and an inner circular periphery. One circular periphery is a workpiece gripping surface, and the other circular periphery has a tapered cam surface engageable by a workpiece chuck actuator member. The tapered cam surface has a plurality of circumferentially spaced apart slots having an open outer end. In an internal collet the tapered cam surface is formed around the collet body inner periphery.

Abstract: A nonadjustable shock absorber that can accommodate for variations in weight, and propelling force, and to provide a specific deceleration or reaction force. The shock absorber provides dual function metering that combines soft contact dampening with the self compensating ability to decelerate a wide range of weights. The shock absorber includes a low pressure zone, a hydraulic cylinder having a high pressure zone chamber, a piston in said cylinder for movement under a shock load through a predetermined stroke length, a fluid pathway metering control means, having four fluid metering pathways of which the first three fluid metering pathways are approximately linear spaced apart, for controlling high pressure fluid escaping from the high pressure zone chamber into the lower pressure zone, ahead of the piston as the piston moves from an initial position in response to a shock load through a total stroke to a final position, to create five control zones during the compression of the shock absorber.

Abstract: A portable electromagnetic drilling machine which is provided with an enclosed motor power control cord that connects the machine electrical control panel to a machine electric drive motor for a cutting tool spindle. The provision of an enclosed electric motor power control cord eliminates any wrongful or inadvertent lifting of the machine by said cord, and insures the lifting and carrying of the machine will be carried out by a handle on the machine housing.

Abstract: A preconstruction utility meter pedestal for the purpose of providing underground electrical and communication service to a building construction site after a foundation has been constructed but before a building has been erected upon the foundation. The pedestal comprises an elongated, vertical electrical service rigid steel conduit for conducting electrical service from an underground electrical service system to a utility meter box mounted on the upper end of the conduit and having an electric meter mounted therein. The rigid steel conduit is adapted to be fastened by an upper and a lower mounting plate, respectively, to the front face of the foundation. A communication cable plastic conduit, and a temporary electrical power box are carried by the electrical service rigid steel conduit. The electrical service rigid steel conduit supports a telephone interface box mounting bracket for the reception of an interface telephone box.
