Abstract: A well cutting tool for cutting casing in a well bore having a cutter body and at least one cutting arm pivotally mounted in a longitudinally extending slot of the cutter body. The cutting arm has removable and replaceable cutting inserts positioned along its outer front surface and its lower end surface. A removable and replaceable projection on the upper end of the cutter arm is provided for contact by a fluid pressure actuated piston for outward pivoting of the cutter arm into cutting position.

Abstract: Apparatus for attaching a device or element or the like to a work piece such as a panel or the like. Support structure supports a carriage which carries drill mechanism, liquid applicator mechanism, and rivet injector mechanism. The support structure also supports swage mechanism. A work piece is clamped in a given desired position, and the carriage sequentially moves the mechanism to drill, apply liquid, and to inject rivets through a predetermined portion of the work piece. An element or device is applied to the work piece so that the rivets extend through the device as well as through the work piece. Then swage mechanism swages the rivets to attach the device to the work piece.

Abstract: A method of cutting and retrieving submarine well casing which includes the steps of lowering a tool on a string into the bore of the well casing which tool includes a casing cutter, a bumper sub connecting from the cutter to the combined anchor swivel and latching means to retain the anchor in unset position when it is being run with the string connected to the upper end of the tool, landing the tool with the swivel supported on the upper end of the casing and the remainder of the tool within the casing, releasing the latching means, raising the string to set the anchor, tensioning the string, energizing the cutter arms, rotating the string to cut the casing, and raising the string to retrieve the cut casing. The apparatus includes a casing cutter, a bumper sub, a combined anchor swivel and latching means to retain the anchor in unset position which latching means is actuated to unlatched position by manipulation of the string on which the tool is supported.

Abstract: Riveting apparatus is shown to comprise a riveting spindle mounted for vertical reciprocating movement in a frame under the influence of a cam controlled lever and a reacting spring means. A motor in driving relation to a rotary shaft embodied in the spindle operates a wobble type riveting tool. Depending on the embodiment the same or a separate motor functions to drive a cam device, through the medium of which the lever is uniformly and periodically cycled to produce a vertical movement of the spindle which carries the riveting tool to and from an underlying work piece. One end of the lever is connected with the spindle while the other is pivotally anchored to the projected extremity of the piston rod of an air cylinder. The latter may be set to fix the operative position of the projected extremity of the piston rod and thereby the pivot point of the lever.

Abstract: An improved drive train for a progressive cavity device is disclosed. The progressive cavity device has a rotor, a stator, means for fluid to enter between said stator and rotor, and means for fluid to exit therefrom. The rotor is adapted to roll with respect to the stator. The improved drive train comprises means attached to the rotor, for rotation substantially about a single axis, whereby the rolling of said rotor and the rotational motion about said single axis are directly connected and are at different speeds. At least a portion of said means attached to the rotor is aligned with the true center of the rotor.
