Toiall whom t may comem: Be. it linorwn that I, THOMAS E. RoemsON, ay citizen of the United States, residing at Tulsa in the county of Tulsa and State of Oklahoma, have invented certain new Clamps', of which the following` is a 'specihcation My invention relates generally, tooilwell apparatus and in particular to well-casing clamps. Objects thereof are: a separable clamp for supporting and holding a Well casing, the component parts thereof being secured by interlocking engagement; a clamp of this character adapted to engage a ycasing at any point; ay clamp provided with insertable casing gripping means, and means to p-reventspreading of the clamp when supporting a casing. Other objects will' be apparent from the description.
novel construction, combination land ar. rangement of parts hereinafter described and claimed, and illustrated in the accomf panying drawings, of which;

- The central portion of each side member is provided with a semioircular. bore so lthat when in assembled position, the base will 'surround a well casing section 3. f'lhe'face ofeaoh semicircular bore or 'recess is tapereddownwardly for wedging engagementwith a reversely tapered semicircular clamping.
