Depending upon the size of the vessel and the probes or devices involved, the body may be substantially elongated and have an overall length dimension of approximately a meter or more. The inner end of the body is provided with an exterior flange indicated at The flange provides a sloping exterior shoulder 73 at the inner end of cylindrical exterior surface 74 which accommodates a hammer union 75, seen in FIGS. The hammer union rotates freely on the inner end of the tool body and is held in place in assembled condition with the body by a snap ring 76 which fits within slot The hammer union has interior coarse threads 79 on its lower projecting end which mate with the exterior coarse threads 32 on the stuffing box assembly The hammer union is also provided with radial projections indicating at 80 which enable the hammer union to be rapped by a hammer.

The lower end of the interior of the tool body is provided with a significant bevel indicated at The surface 82 acts as a pilot surface to enable the tool quickly and easily to be placed over the collet lock nut 50 so that the annular end 83 of the tool body is close to the annular top shoulder surface 34 of the stuffing box fitting. The interior of the inner end seen at 85 is a flatted socket adapted to mate with the exterior of the collet lock nut The tool body is thus in the form of a socket wrench, and the socket 85 is adapted to fit the collet lock nut Immediately beyond the lock nut socket 85, the tool body is provided with four quadrant spaced axially elongated windows seen at 86, 87, 88, and Such windows are shown in dotted lines in FIG.

Outwardly of the windows, the tool body forms a polished uniform diameter cylinder 91 which accommodates hydraulic piston 92 for axial sliding movement therein. Within the axial reach of the windows near their inner ends, there is provided a piston stop shown generally at Piston stop is simply a tapered inward projection from the diameter of the cylinder of the assembly and would be annular, but for the interruption by the windows.

The exterior of the body outwardly beyond the windows is provided with hexagonal flats seen more clearly at 95 in FIG. Such flats interfit with interior flats in the hub 96 of handle The handle is held in place by snap ring 98 fitting within groove Accordingly, the handle may readily be assembled over the outer end of the tool and secured in place by the noted snap ring. With the handle, the tool may readily be rotated around its elongated axis. The outer end of the tool body includes internal threads in the somewhat enlarged wall thickness end , such threads accommodating cylinder end cap assembly The end cap assembly includes an externally threaded inwardly projecting skirt A dowel pin extends diametrically of the skirt.

The end cap assembly is provided with an axially extending threaded hole which accommodates hydraulic hose fitting extending axially of the tool as indicated at in FIGS. Extending around the dowel pin is a continuous elastic shock cord or bungee tube or cord The shock cord also extends around diametral dowel pin in piston Accordingly, there are four strands of the continuous elastic shock cord extending between the end cap assembly and the piston 92, all within the cylinder The hydraulic fluid employed should be compatible with the material of the elastic shock cord.

Anytime the piston moves away from the end cap assembly, the shock cord elastically elongates creating a return force which increases with the distance between the end cap assembly and the piston. The piston includes the sliding seals seen in FIGS. The outer end of the plug is provided with a transverse slot seen at in FIG. The button plug may easily be inserted or removed by a screw driver projecting through the inner end of the tool when the piston is extended against the stop Alternatively, as seen in FIGS.

The pump handle is shown at The other end of the street tee is connected to pressure gauge The pump includes a variable manually operated relief valve The hose may be about three meters in length and the pump hose and tool may be bundled together to form a readily portable package easily handled and operated by a single person.

The hose fittings are such that they may readily be connected and disconnected without loss of hydraulic fluid. For insertion, the access valve will be closed, the probe or device and stuffing box will be assembled in a retracted position so that when the stuffing box is assembled to the adapter nipple, the inner end of the probe will clear the closed valve.

The collet lock nut will be latched, and the collet latch will lock the shank of the probe or device to the stuffing box fitting. The dust cover and safety clamp are removed from the probe end. At this point, the tool is installed on the stuffing box fitting 30 as seen in FIGS. The tool is installed simply by tightening the hammer union. Next, the hydraulic hose may be attached between the pump and tool.

With the pump relief valve in the closed position, the pump handle is then operated to extend the piston against the retraction pressure of the elastic shock cord. When the piston engages the probe projecting from the stuffing box fitting, the pressure shown on the gauge will start to go up. This indicates that the probe is now being backed by the piston. At this point, the access valve is now open slowly to pressurize the fitting. After pressurizing the fitting, the handle 97 is employed to rotate the tool a few turns on its axis counterclockwise looking inwardly to release the collet lock nut permitting the collet fingers to disengage from the probe shank.

The probe can now be installed into the system through the now open access valve simply by using the pump. The windows in the tool body may be employed to verify that the probe is at the correct insertion depth. This can often be done simply by measuring and marking the probe which mark will become visible as it moves into the window.

When at the correct insertion depth, the tool is then rotated clockwise using the handle 97 to lock the collet in place. The operator should verify that the collet is holding the probe in the inserted position by opening the relief valve. As the relief valve is opened, the probe should not move. Once it is verified that the collet is properly holding the probe in place, the tool can now be removed from the system by unlatching the hose and backing off the hammer union.

The operator must then reinstall the safety clamp kit and the dust cover.

The reverse procedure is employed to retract the probe. With the tool installed and the pump connected, the probe is backed by the piston under pressure. The probe can then be retracted from the system. The operator rotates the tool counterclockwise a few turns to release the probe from the collet. The operator then slowly opens the relief valve on the pump to retract the probe from the system. The pressure differential between the vessel and the hydraulic system is normally enough to force the probe outwardly.

Once the probe is clear of the access valve, the access valve is closed. At this point, the bleed valve 58 is slowly opened. When the pressure between the fitting and the valve is bled down, the tool can now be removed from the fitting and the fitting which includes the probe or device removed from the valve nipple In the event that the probe does not retract into the tool, it may become necessary to attached the probe or device to the piston. The operator rotates the tool a few turns clockwise to relock the collet retaining the probe.

The operator then opens the relief valve to verify that the collet is holding. The operator then closes the relief valve and removes the tool from the fitting. The operator then pumps the piston to the front of the tool until it contacts the stop Because of the configuration of the stop, the stop will keep the piston from rotating. Then using a large slotted screw driver from the inner end of the tool, the plug may readily be removed.

With the plug removed, the operator places the tool over the probe and threads the tool piston onto the probe by rotating the entire tool clockwise. It is noted that with the piston extended and locked against the stop 93, the collet lock nut socket 85 is well above the collet lock nut. The socket can engage the collet lock nut only when the piston is retracted and the hammer union is able to engage the stuffing box fitting.

After the tool piston is secured to the probe or device, the operator may then open the relief valve which will cause the tool to be pulled over the probe and onto the fitting.

After the hammer union is tightened, the operator again closes the relief valve to ensure that the probe is backed by hydraulic pressure. The operator may then rotate the tool a few turns counterclockwise to release the collet latch holding the probe.

The probe can now be pulled up into the tool by opening the relief valve slowly. At this point, the internal pressure of the vessel as well as the force of the elastic shock cord is acting on the probe.
