<p>A shingle gauge (25) for use with a nail driving tool of the type having a magazine (2) which feeds nails (22) into a guide body (10) to be driven through shingle elements (74, 75, 76) into a roof structure (34) and having a shingle element locating surface (9) adjacent the guide body nose. The gauge (25) comprises a mounting bracket (26) fixed beneath the magazine (2) and a gauge element (27) slidably and pivotally supported on the bracket (26) and shiftable therealong toward and away from the locating surface (9) to adjust the distance therebetween to accommodate various sizes of shingle elements (74, 75, 76). A latch (68) is attached to the gauge element (27) and is capable of a locking engagement with the support bracket (26) at any selected one of a plurality of predetermined positions therealong to locate and lock the gauge element (27) at that selected position. The gauge element (27) is pivotable between a first position in which the latch (68) is in locking engagement with the mounting bracket (26) at one of the predetermined positions therealong and a second position in which the latch (68) is out of locking engagement therewith. The gauge element (27) is biased to its first position. The attachment between the gauge element (27) and the latch (68) is adjustable to provide a fine positioning adjustment of the gauge element (27) to compensate for wear or the like.</p> |
