US Patent:

45111685, Apr 16, 1985

Filed:

Feb 7, 1983

Appl. No.:

6/464521

Inventors:

Charles W. Haynes - Spring TX

Assignee:

Joy Manufacturing Company - Pittsburgh PA

International Classification:

E21B 1907

US Classification:

2941022

Abstract:

Slip mechanisms for selectively gripping and releasing conduit in a well drilling operation, particularly useable as elevators or spiders. Three slips are positioned within a tapered bore of the slip mechanism having a split front opening, and are articulatingly suspended from a vertically movable ring. Upon lowering of the ring the slips move downwardly and inwardly along the tapered bore to simultaneously and evenly grip the conduit. Upon raising of the ring the slips move upwardly and outwardly along the tapered bore and disengage from the gripped conduit. In the disengaged position two of the three slips are circumferentially slidable, through the suspension connection to the ring, to a position spaced from the front opening and adjacent the third slip, whereby the slip mechanism is laterally movable from, or about, the conduit. A funnel shaped guide skirt is mountable on the bottom of the mechanism when operation as an elevator is desired.

Appl. No.:

5/791752

Inventors:

Charles W. Haynes - Spring TX

Assignee:

Joy Manufacturing Company - Pittsburgh PA

International Classification:

B25B 1700

US Classification:

81 5715

Abstract:

This invention relates to a door mechanism for a rotary power tong, such as used in well drilling operation. The door is pivoted to one of the bifurcated portions of the tong and a door locking mechanism is used to attach the swinging end of the door to the other bifurcated portion of the tong. At least one contact surface is attached to the door to transmit forces to the door and engage a hook-like member attached to the tong frame. At least one contact member is attached to the frame to transmit forces to the frame and engage a hook-like member attached to the door. Such contact engagements provide for door support in both radial and tangential directions.

Appl. No.:

6/278293

Inventors:

Charles W. Haynes - Spring TX

Assignee:

Joy Manufacturing Company - Pittsburgh PA

International Classification:

B25B 1700

US Classification:

81 5718

Abstract:

A rotary tong for use in well drilling operations to make up and break out drill strings or similar axially elongated objects which has a secondary camming action provided by the jaw assembly. By use of the inventive jaw assembly a secondary camming action is produced which reduces the cam angle of the primary camming function. The reduced cam angle gives greater gripping force thereby reducing slippage. The secondary camming function also allows the jaw to be used for a greater variety of drill string sizes thereby reducing the need to change tongs or jaw elements when drill string sizes change.

Assignee:

Joy Manufacturing Company - Pittsburgh PA

International Classification:

B25B 1700

US Classification:

81 5718

Abstract:

A rotary tong used in well-drilling operations to make-up and break-out drill strings which incorporates readily-interchangeable sets of jaws, one of which may be used for drill pipe and the other of which can be used for relatively thin-walled well casing.

Appl. No.:

6/103258

Inventors:

Charles W. Haynes - Spring TX

Assignee:

Joy Manufacturing Company - Pittsburgh PA

International Classification:

F16D 300

US Classification:

64 235

Abstract:

An improved kelly is provided with a drive section which has a uniform cross section defined by three generally flat drive sides alternating with three generally arcuate sides. The three arcuate sides are spaced an equal radii from the central axis of the kelly and the three flat drive sides lie in planes that form an equilateral triangle therebetween. The improved kelly is driven by an improved mating kelly drive bushing which has three rollers positioned so as to evenly transmit torque to the three flat drive sides of the kelly simultaneously.
