US 4,056,889 A · Strip shingle alignment fixtures

Abstract

Fixtures for aligning asphalt composition strip shingles for roofing and siding are disclosed. An elongated alignment guide is provided for supporting the lower edges of a plurality of shingles to be laid on a roof or attached to a building wall. In one embodiment, the alignment guide comprises a plurality of sections, some equal in length to two standard strip shingles; and some, to a single standard strip shingle, thereby permitting the assembly of alignment guides of various lengths from one to a desired number of standard shingle lengths. A clamping device attached to the alignment guide includes a pair of essentially flat, opposed jaws which are connected by spring-biased levers, for compressing the jaws together to grip a shingle in a previously laid row of shingles. A horizontal stop on the clamp or the guide positions the device so that successive rows of strip shingles are staggered relative to each other.

Dependent claims

An improved alignment fixture for use with asphalt composition strip shingles for roofing and siding, comprising:

an elongated horizontal alignment guide for simultaneously supporting the lower edges of a plurality of strip shingles to be laid;
a plurality of selectively, horizontally adjustable spacer means attached to said guide for spacing said strip shingles at predetermined itervals along said guide;
clamping means for attaching said guide to a previously laid row of strip shingles in parallel relation thereto;
and
means joining said clamping means and said guide for permitting selectively adjustable horizaontal movement of said guide relative to said clamping means while said clamping means is attached to said previously laid row, whereby said strip shingle to be laid may be properly positioned relative to said previously laid row without requiring removal of said clamping means from said previously laid row.
