Abstract: A walking substructure device having a drilling rig substructure. A plurality of lifting jacks is provided, each lifting jack having an upper end and a lower end, the upper end connected to the drilling rig substructure. A plurality of roller assemblies is provided, each roller assembly connected to the lower end of one of the jacks, each roller assembly pivotal radially about an axis of the lifting jack. A plurality of jack pads is provided, with each jack pad having a center beam wherein one of the roller assemblies engages the center beam and rolls thereon. A push-pull mechanism extends between each jack pad and each roller assembly in order to move the shoe assemblies in relation to the drilling substructure.

Abstract: The crown block has two parallel clusters of sheaves. In one use the crown block is positioned such that the center of the derrick passes through the axle of one of the clusters and a power cable is threaded through the first cluster of the crown block and the cluster of the traveling block. When one wants to double the mechanical advantage, the crown block unit is shifted so that the center line of the derrick passes midway between the axle of the first cluster and the second cluster of the crown block. For this second use a modified traveling block is used which also has two parallel clusters of sheaves which corresponds to the two parallel clusters of sheaves of the crown block. The power cable is then threaded between the first clusters of the crown block and the traveling block and then through the second sheave cluster of the crown block and the second sheave cluster of the traveling block. The load is connected to a cross member between the two axles of the clusters of the traveling block.

Abstract: A portable apparatus for drilling deep boreholes in the earth, comprising a sub-base structure, a drawworks platform supported on four legs hinged both to the sub-base structure and to the drawworks platform and when in lowered position extends away from a first end of the sub-base: A mast hinged to the sub-base structure by two legs and in the lowered position extends away from the second end of the sub-base; a pulling means has a sheave through which a slingline cable is passed, and the two ends of the cable are separately connected between the mast at a selected point, and a pulley mounted on the drawworks platform so that in one continuous pulling motion of the pulling means, the drawworks platform is first raised into vertical position, and then the mast is lifted until both parts are fully erected on the sub-base.

Abstract: An improved portable drilling rig for drilling deep boreholes in the earth, in which the table or working floor of the rig, on which the rotary table and draw works are supported, is on a separate framework supported on and attached to a structural frame or base, for the drilling rig. The floor structure is broken down into a plurality of parts for ease in transportation, each of which have independent columns and cross-bracing. The central portion of the floor which supports the rotary table, and which must support the full weight of the drill pipe, has special heavy columns which are supported on a structural base in substantially the same position as the base connection of the mast, when in a raised position. Therefore, weight can be transferred from the rotary table to the crown block and vice versa, and the weight is still applied to the base frame in substantially the same position.

Abstract: An improved portable drilling rig for drilling deep boreholes in the earth, in which the mast is rotatable to a horizontal position at a small distance above the ground. The mast is of rectangular construction, with four corner columns, and four support legs. While the mast is supported in a vertical position with four shoes, it rotates about the two back supports.The mast is supported on two longitudinal stiffening members, of a U shape in cross-section. When the mast is lowered to a horizontal position, the front supporting columns drop below the top surface of the U shaped stiffening members and rest on the shallow bottom of the space between the two arms of the U. This puts the bottom of the mast within a foot or two above the ground, so that workmen may find it convenient to do work on the mast itself.

Abstract: This abstract describes the power compound portion of a bore hole drilling system, which is designed for drilling medium depths of wells, and is designed for portability so that each part of the system can be broken down into subassembly units which are of less than a selected total weight. Thus, the entire system can be transported by helicopters capable of carrying said selected weight. The power compound comprises a self-contained engine manifold to which can be coupled two engines through corresponding gear transmissions to two input shafts. The transmission system in the manifold comprises drive means for driving a pump from each engine through a clutch, at a selected lower speed. It also comprises drive means for coupling the two engine shafts to provide combined power outputs to a shaft which drives the draw works.

Abstract: This disclosure describes a drilling mast system which is adapted to be assembled section by section in a vertical position, as distinguished from the conventional method of raising a drilling mast by assemblying the mast in a horizontal position on the ground and then lifting the mast into a vertical position. The mast is made of a base section and a plurality of upper sections, each one adapted to be mounted on top of the one below it and fastened thereto. After the base section has been assembled on the foundation, the succeeding sections are assembled on the ground or are lifted in pieces and assembled in place on top of the previous section by means of a floating gin pole. The gin pole is supported inside of the mast by means of a plurality of basket cables.The sections of the mast are made of rectangular horizontal cross section. The floating gin pole extends above the top of the topmost assembled section, and can tilt to the outside of the mast, so as to lift section parts outside the mast.

Abstract: This invention is directed to a deep bore hole drilling machine which is designed for portability so that each part of the system can be broken down into subassembly units which are of less than 4,000 pounds total weight. Thus, the entire drilling system can be transported by helicopters which are capable of carrying a total weight of 4,000 pounds.
