of the shank they will also embrace the pro
jecting portion of the member 32 and lock
said member and likewise the pin 30 in po
sition.
A blade 45 has flanged portions 46 which
engage over the edges of the shank 11 and
when the screw 28 is rotated sufficiently the
blade will be clamped to the shank 11 and
10 secured in place. The lower end 47 of the
blade 45 engages the shoulder 27 of the lower
end 49 and the blade 40 engages a shoulder 46.
A plate 50, shown more particularly in
Fig. 10, has a notched portion 51 adapted

This plate is fitted between the edges of the
flanges 41 and a similarly constructed plate is
fitted between the edges of the flanges 46
of the blades 45 to cover the heads of the
20 screws 21 and 28.
When it is desired to remove the blades
for the purpose of replacing the same it is
only necessary to remove the plates 50 and
loosen the set screws 21 and 28 whereby the
blades 40 and 45 may be slipped respectively
from the shanks 10 and 11.
I claim:
A pair of scissors comprising a pair of
shanks, blades removably connected with the
30 shanks, said blades having flanges embracing
the shanks, set screws carried by the shanks
and engaging the blades for clamping the
flanges to the shanks, a pin secured to one
shank and provided with a flange, the other
35 shank having a recess to receive said flange,
the last-mentioned flange being engaged at
diametrically opposite points by the flanges
of the blade which embraces the shank having
the recess, plates provided with notches to
4) receive the pin and having the edges thereof
frictionally co-acting with the edge of the
fanges in a blade. . -
