<p>U-BOLT CLAMP SADDLE A saddle for a U-bolt clamp is constituted of a pair of tubular housings arranged to receive and slide axially upon the legs of a U-bolt having a semicircular bight, with the housings connected by a web portion consisting of a pair of parallel planar sections of sheet steel welded together in full face contact and extending transversely between the housings integral therewith. The upper (bight facing) edge of each planar section is curved as a semicircular recess curved on the radius of the U-bolt bight. The lower portion of each planar web section is, for the major portion of its length between the tubular housings, doubled back upon itself in flat face contact with the outer face of its associated planar web section, thus providing a double thickness for each web section throughout the area covered by the doubled back portion and materially reinforcing the entire web portion of the saddle both horizontally and vertically with four thicknesses of the sheet steel from which the saddle is made. The upper edge of the doubled back reinforcement is spaced distally below the bottom of the semicircular recess of its associated web section and is formed with an out-turned lateral flange over its full length, which flange lies in a plane normal to the longitudinal axes of the tubular housings and additionally reinforces its web section against horizontal distortion when securing nuts threaded on the ends of the U-bolt legs are drawn up against the lower end faces of the tubular housings to tighten the clamp.</p> |
