Filed:

Dec 11, 1986

Appl. No.:

6/940742

Inventors:

Michael C. Catapano - Middletown NJ

International Classification:

B23B 4902

US Classification:

408 79

Abstract:

The fixture, in a first embodiment of the invention, comprises a flat base having a plurality of mounting holes formed therein, and a platform supported above the base, by a plurality of legs integral with both the base and platform. The base and platform are in parallel planes, and the platform has a guide bushing slidably engaged with an aperture formed in the platform. A lock screw, threaded into a tapped hole formed in the platform adjustably secures the bush in place. Plugs engageable with tubes in the tubesheet are passed into the mounting holes in the base to fix the base securely to the tubesheet, and the bushing receives therein a drill for drilling out a tube, in the tubesheet, which is directly aligned with the bushing. The bushing has an arcuate cut-out formed therein to accommodate the withdrawal of the bushing from the platform, without having to release the plugs, and its replacement by another bushing to facilitate reaming of the tubesheet. The cut-out permits the bushing to be extracted right past the lock screw.

Abstract:

The unit comprises a mobile chassis having an enclosure mounted thereon, in which enclosure are compactly and efficiently confined an air-operated hydraulic pump, a water conduit for admitting water to the pump and for discharging pressured water therefrom, and a compressed-air conduit, for admitting operative compressed air to the pump, together with a pressure regulator for the air. The enclosure has a control panel through the face of which are mounted air and water inlet connectors for the conduits, and a water outlet connector. Air and water inlet valves, interposed in the conduits, are also mounted on the control panel, as well as a water discharge valve; the latter is interposed in the discharge end of the water conduit. Finally, air and water pressure-indicators, which communicate with the respective conduits, are fixed in the panel, and a pressure-setting regulator, which communicates with the air conduit, is secured in the panel.
