gage, piece and tooth

GABLET, a small gable ; an ornament in shape like a gable, frequently introduced over niches, but tresses, &c.

GAGE, (French) in carpentry and joinery. an instrument for drawing one or more lines on any side an, piece of stuff, parallel to one of the :arises of that side.

There are four kinds of gages: the common gage, the moĽ tise-and-tenon gage, the internal gage, and the flooring gage. The common gage and the flooring gage are both applied to the drawing of a line parallel to an arris.

The common gage consists of two pieces of wood, one of which passes through a mortise in the other, and has an iron or steel tooth fixed near one of its extremities ; so that the point may be placed at any distance from the mortised piece: then the piece which passes through the mortise is fixed by a wedge also through that piece : the piece through which the mortise passes is called the head, and the piece passing through the mortise, in which the iron tooth is fixed, is called the When a line is drawn from the arris upon one side, at a given distance, the head is a fence that always keeps the staff at right angles to the arris, and equidistant, in moving it to and fro.

The mortise-and-tenon gage is a common gage with a lon gitudinal slider, moveable in a dovetail groove : the slider has also a tooth fixed as near to the end next the tooth in the end of the staff as possible; so that the teeth may be brought almost to any distance from one another.

The internal gage is constructed similar to the staff of the mortise-and-tenon gage : it has a longitudinal slider, the whole length of the staff; without a head, or any other tooth than that of the slider.

The flooring gage consists of a head and staff fixed toge ther, at a very obtuse angle : on the head are a number of equidistant furrows at right angles to the staff: the section of each furrow is an internal right angle, one side of which is in a straight line with the tooth, and the other becomes a fence in the act of gaging.

This gage is made to answer battens or deals of various widths : Each width is numbered. according to the furrow that is applied as a fence ; so that a flooring hoard, which is not sufficiently long, may be extended, by a piece of the same to the length required.
