Description : Releasing Spears provide a dependable, inexpensive, and simple means
of engaging a fish internally. These Spears assure positive engagement, easy release
from the fish when desired, and easy re-engagement after the Spear has been released.
Features: Releasing Spear consists of a Mandrel, Grapple, Release Ring, and Nut. The
Mandrel may be obtained in either a Flush Type or a Shoulder Type. Mandrel top connections
are furnished to order. The Nut can be obtained as a plain bull nose guide or with a pin
connection for the attachment of other tools below the Spear.
Assembly and Operation:
To Assemble: Screw the Grapple onto the Mandrel from the lower end with a left-hand action.
Slide the Release Ring on below the helical section of the Mandrel and make up the Nut to the
Mandrel. Before running in, screw the Grapple down against the Release Ring as far as it will
go by hand. In this position, the Grapple will compress inward and will not engage the pipe
sufficiently to interfere with the tool being run in.
To Engage the Fish: When the Spear has reached the point of desired engagement with the fish,
rotate sufficiently to move the Mandrel one full turn to the left. This turns the Mandrel down through
the Grapple, placing the Grapple into the engaging position. A straight pull will then wedge the
Grapple into positive engagement with the fish.
To Release: Bump down to break the freeze, then rotate two or three turns to the right. This moves
the Mandrel up through the Grapple, forcing the Grapple against the Release Ring and putting the
Spear in released position. A straight upward pull will then generally free the Spear; however, it is
recommended that the Spear be rotated slowly to the right when coming out. The matching cams
of the Release Ring and Nut constitute a safety device which resists freezing or jamming.
