LINGO A clamp for a boring mill, so designed as to permit theboring and turning of a tire at one setting, is shown in thedrawing. A complete set consists of four of these clamps;all of tlie parts shown and the necessary keys and set screwsare made of steel. To set up a tire on the mill ready forboring, the Ijlocks C are secured to the table at the properpoints for the diameter of the tire to be bored. The tire isplaced on the blocks and the clamps B inserted through theblock, on the outside of the tire, and then keyed in positionthrough the slot shown in the drawing.

The upper portion of the clamps .1 are directhover the tire and the l,4-iii- set screws are tightened againsithe tire, holding it finnly to the block. The clamps B arethen removed and the tire being secured by the clamps A,may be turned without resetting. This method is very useful in a shop turning out extratires of varying diameters and tread thicknesses for replace-ment of worn tires at other points on the road, and canalso be used with equally good results in turning new tires.
