Abstract: A sighting device for a golf putter comprises a mounting frame housing an eye aligning mirror having a horizontally disposed reflective surface and a ball and target aligning mirror having a reflective surface extending at an angle of approximately 135.degree. to the putting face of the putter blade. The frame includes a front flange which extends downwardly over the putting face of the blade. The device is releasably mounted on the blade by a deformable bonding agent which fills a chamber defined by the rear face of the flange, the striking face of the putter and spaced-apart ribs extending rearwardly of the flange to engage against the striking face. A pair of lugs extend sidewardly of the frame and each is formed with a through hole in which an adjusting screw for adjusting the position of the device on the putter blade are threadingly engaged.

Abstract: A support assembly for shelving comprises a shelf supporting bracket having a rearwardly projecting tongue for interfitting in a complementary outwardly facing channelled groove in an upright. The bottom corner of the tongue is cut-away to form an upwardly extending slot for reception of a hollow cylindrical shaped body of resilient material which urges the lower portion of the tongue forwardly against the front face of the groove and prevents movement of the tongue along the upright.In another aspect of the invention an elongate member is inserted into the slot at one end to push the tongue forwardly against the front face of the groove and at its other end rests on another shelf supporting bracket to fix the upper bracket in position relative the upright.
