A tool which is intended for gauging convex
and concave as well as straight work, and known as Winslow's
Adjustable Face Marking Gauge, is being introduced to the
trade by the Mossberg Wrench Company of Central Falls, R. I.
The construction of the tool is such that
the gauge can be readily adjusted for any class of work. In
order to set it for curved work it is only necessary to
loosen the thumb screw on the underside of the gauge, press
the face against the edge of the work to be gauged so that
it accommodates itself to the work, and then tighten the
thumb screw again.
For straight work the gauge is set in the
same manner, adjusting the gauge face to the straight edge
at right angles to the gauge bar. Double line gauging is
accomplished by means of a removable marker, carried on a
The latter is mounted in a slot in the gauge
bar and is adjusted and secured in position by means of a
thumb screw conveniently located on top of the bar. In Fig.
5 of the illustrations is shown a general view of the gauge,
while in Fig. 6 is shown the manner of using the gauge for
An interesting feature of the tool is the
absence of the bulky block which is often found on tools of
this nature surrounding the bar and obstructing the hand in
using the gauge.
The sleeve to which is attached the
adjustable face of the marking gauge can be held by the
sleeve as readily as by the bar, while at the same time it
in no way interferes with the hand or fingers when the gauge
is held by the bar.
The gauge face is adjusted to and from the
marking points by means of a thumb screw on top of the
sleeve. Inside the sleeve and bearing on the bar is a flat
spring which holds the sleeve by friction and prevents it
from sliding from the bar when the thumb screw is loosened.
The gauge is furnished with a rosewood bar
of the first quality, and all metal parts are heavily
nickeled and highly polished.
