Abstract
901,523. Spanners. IVES, H. H., and RUSH, D. A. Oct. 14, 1959 [Jan. 20, 1959], No; 2170/59. Class 61. A box spanner having a tubular body suitably shaped at one or both ends to fit over a sparking-plug comprises spring means for detachably holding the sparking-plug in the spanner. As shown, a ring spring 8 is seated in an internal circumferential groove 7 in the box spanner 1, the ends 9 of the spring being bent back and shaped to clip over the top of the porcelain portion 11 of the sparking-plug 4. A shoulder 6 inside the spanner limits the extent to which the plug can be received in the spanner. Two diametrically-opposite holes 12 are provided to receive a tommy-bar. In a modification, two coil-springs extending transversely inside the spanner are anchored in transverse holes in the spanner. In another modification, a square hole is provided in one end of the spanner to receive the square end of a key. A forked handle, Fig. 7 (not shown), a cranked handle, Fig. 8 (not shown), or a tommy-bar, Fig. 9 (not shown), may be provided.
