This invention consists in an improved form of weather-board
hook, in combination with a fluid-level, graduated rule, marker,
and gauge, the whole constituting a carpenter’s combined tool,
of great utility and convenience.
In the drawings, the body of the tool, which is of wood, is
represented at M. It is about twelve inches in length,
one inch in thickness, as seen in figs. 2 and 3, and from one
to two inches in width, as seen in fig. 1. The back, front,
and one of the sides, seen in fig. 1, are covered with a smooth
brass plate. The sides and back are perfectly straight and smooth.
The middle portion of the front side, about seven inches in
extent, is also smooth and straight, parallel to the back, and
about an inch distant from it, and is terminated at either end
by the perpendicular walls of two shoulders, I I, as seen in
figs. 1 and 3. In the centre of the portion last described is
a spirit-level, H, designed for any use to which the carpenter
may find it convenient to apply it. The back of the tool is
formed into a scale or rule, O, shown clearly in fig. 2, graduated
from a spur, G, as a starting-point, into inches and fractions
of an inch. A slide-gauge, F, moves back and forth along this
graduated plate; being operated by a screw, E, provided with
a projecting handle, D. The slide-gauge can thus be set at any
distance from the spur G, and forms a convenient and useful
spacing-gauge for laying off the dimensions of the work. That
side which is covered with the brass plate, shown in fig. 1,
is provided with a long groove, C, in which a handle, A, slides
back and forth. The handle is composed of three pieces — a plate
working back and forth in the slot under the brass plate, and
having a central ridge, which projects slightly out of the slot;
another plate, a, resting upon the ridge of the first plate;
and a screw, having a handle, a1, which screws through the plate
a, and forces it down upon the under plate. The plate a, has
a notch across its under side, in which lies a sharp-pointed
blade, B, the end of which projects over the edge of the instrument,
and serves as a marker. By unscrewing the handle a1 the plate
a can be raised and the blade removed. By screwing the handle
down again, the marking-blade is confined between the two plates
of the handle A, so that it is held firmly, while at the same
time it can be slid back and forth along the space between the
shoulders I I. In gauging the width of the board, or the width
of the level along its edge, the spur G and gauge F will ordinarily
be used. But in marking across the board, the instrument may
be simply hung upon the edge of the board by one of the shoulders
I I, and the line may be marked square across with the utmost
accuracy, by means of the sliding knife B. The weather-board
can be levelled by the level H, and any measurement that is
needed may be taken by the scale or rule O.
Having thus described my invention, what I claim as new, and
desire to secure by Letters Patent, is—
The weather-board hook M, having the shoulders I I, when used
in combination with the scale O, slide-gauge F, spur G, and
sliding marker B, the whole being arranged in one instrument,
and forming a combined tool of the character and for the purposes
set forth.
