Patent number: 4047582Abstract: A portable earth boring machine for the boring of vertically inclined shafts and the insertion of pipeline casing sections characterized by a main frame portion that supports the auger drive and casing pusher apparatus, and a detachably mounted engine frame portion that permits the transmission of power between the engine and the auger drive and casing pusher apparatus not only when the engine frame portion is positioned on the main frame portion at the boring location but also when said engine frame portion is detached and positioned at a location remote from the main frame means. The machine is further characterized by a novel control means for the casing pusher apparatus that provides for both relatively slow and relatively fast extension and retraction of the casing pusher so as to provide more efficient operation of the earth boring machine.Type: GrantFiled: June 30, 1975Date of Patent: September 13, 1977Assignee: The Richmond Manufacturing CompanyInventor: William S. Appleman

Patent number: 4042046Abstract: A mechanism carried at the forward end of a tubular pipe which is adapted to be driven underground over a considerable distance while maintained at a particular grade level. In the preferred embodiment the control mechanism comprises a cylindrically shaped steering head pivotally mounted to the forward end of the pipe and including means attachable to the steering head for rotating the same a predetermined amount with respect to the direction of movement of the pipe so as to initiate a movement of the pipe in either vertical or horizontal directions. In another version of the present invention a second cylindrically shaped steering head is mounted at the forward end of the first steering head with the second steering head being movable about an axis which is perpendicular to the axis of rotation of the first head whereby the direction of movement of the pipe may be selectively controlled in perpendicular planes.Type: GrantFiled: March 27, 1974Date of Patent: August 16, 1977Assignee: The Richmond Manufacturing CompanyInventor: Anastasio Capoccia

Patent number: 4042043Abstract: A portable earth boring machine for the horizontal boring of shafts and the insertion of pipeline casing sections in installations where excavation from the surface is undesirable. The machine is characterized by frame means adapted for movement along a track means, which frame means supports an engine which drives an earth boring auger as well as casing pusher apparatus for pushing casing sections into the earth fill as the boring operation progresses. The machine is further characterized by a fluid actuated pusher cylinder means for advancing the auger into the earth fill and associated automatic auger feed control means for automatically maintaining a constant fluid flow rate to said pushing cylinder means under variations in resistance to auger penetration of said earth fill during a boring operation.Type: GrantFiled: July 2, 1975Date of Patent: August 16, 1977Assignee: The Richmond Manufacturing CompanyInventor: William S. Appleman

Patent number: 4013134Abstract: A portable earth boring machine for the horizontal boring of shafts and the insertion of pipeline casing sections in installations where excavation from the surface is undesirable. The machine is characterized by a steering head positioned at the front of the casings and remotely controlled by the machine operator so as to directionally control the direction of extension of the pipeline as the drilling operation progresses.Type: GrantFiled: May 20, 1974Date of Patent: March 22, 1977Assignee: The Richmond Manufacturing CompanyInventors: Albert R. Richmond, William S. Appleman
