invention in speci?c terms, it is to be understood
that numerous changes in the shape, size and
materials may be resorted to without departing
from the spirit and scope of the invention as
claimed hereinafter.
Having described the invention, what is
claimed as new is:
1. A taper gauge comprising a frame, a taper‘
horizontal supporting block, a pin and slot con
justable abutment at one end of the upper por-'
tion of the block.
3. A taper gauge comprising a frame, a taper
horizontal supporting block, a pin and slot con
nection between one end of the block and the
frame for vertical adjustment of the block bodily
and for vertical swinging adjustment of the free
end of the block, a ?oating body on the frame
between which and the block a taper is insert

frame for vertical adjustment of the block bodily
and for vertical swinging adjustment of the free
end of the block, a ?oating body on the frame be
tween which and the block a taper is insertable,
and an indicating instrument carried by the
frame and including an operating member
