Abstract

1,176,601. Drilling. H. WOLF. 16 Feb., 1968, No. 7817/68. Heading E1F. Apparatus for lining a bore hole with a pipe I comprises a clamp 2 for the pipe, meansfor example, hydraulic or pneumatic cylinders 3, 4-on a support 12 for oscillating the clamp 2, a piston 5 connected to both the clamp 2 and the support 12, and a cylinder 6 slidable on the piston and connected via links 7, 8 with feet on the ground. Guide rods 10, 11 extend upwardly from the feet through guide tubes 16 secured to a disc (15) rotatably connected to the bottom of clamp 2. The support 12 may have a member extending rearwardly therefrom and passing through a guide member anchored in the ground.
