specify these similar features in a comparative manner,
and in this application for patent I shall attempt to `make
claim only for the obvious improvements.
The jig assembly of this invention is comprised of three
basic parts; the aligning bar, reference number 21, FIG
URES l and 2, the aligning bar brace, reference numeral
22, FIGURE l, and the work centering and holding as
sembly of the jig, which is composed of the parts desig
nated by the reference numerals 25, 26, 27, and 28, and
shown in FIGURES l and 2, and in detail in FIGURES
8 and 9.
The aligning bar 21, has a length, a flat front surface,
two flat sides which extend under toward the center of
the width so that a cross section of the aligning bar would
resemble a rectangle Áwith the center of one long side cut
away, as illustrated in FIG. 5, and contains a bore near
one end which is in the transverse center, and is perpen
dicular to the plane of the sides of the aligning bar. A
pivot pin through this bore and through perpendicular

illustrates how the work centering and holding part 27,
is pivotally held in place by the bolts 25' so the center
axis of this pivot perpendicularly intersects the longi
tudinal vertical center plane of the table element, and
the pivoting of this part 27 allows the proper centering
of the work, regardless of the relative angle of the work
with respect to the position of the aligning bar of the
jig. Here is another improvement over the prior jig, on
which the work holding part is in the form of a rigid V
block extending at a right angle from the jig arm, and is
consequently limited in its centering ability, to work
which is nearly parallel in its relation to the position of
the jig arm.
In FIGURE 8 of the drawings is shown the provision
for holding the work in this jig; a suitable link chain 23, is
linked to the eye of an eye-bolt 30, which eye-‘bolt is passed
through a loose hole in a protruding end provided at one
front end of the `work centering part, and through a com
pression spring of a proper tension 29, then compressed
lugs, or similar, included on the upper surface of the 20 while a washer and a self locking nut are made on the
end of the eye-bolt, the chain can now be pulled snug

side of the slot so the outer surface of these lugs are
parallel with the sides of the aligning bar, and a bore
