This invention relates >to razors and in par
ticular to a safety razor of the type wherein the
prises a knurled member 5 having an axial
threaded bore 6. The head is secured to the
member 5 by screwing the stud 3 into the right
handle assembly is constructed to permit the
blade carrying head of the razor to rotate or re
volve around the axis of the handle and thereby
automatically equalize throughout the length of
the cutting edge of the head its pressure against
the area to be shaved.
Such an automatically
adjusting razor is shown in the patent to Buell
2,126,728. In the Buell patent the handle as
sembly comprises a stem which is drilled and
tapped at one end and screwed on a conventional
blade carrying head in a conventional manner. A
handle in the form of a sleeve is freely rotatably
mounted over the stem. With this type of razor

to be screwed into the opposite end of bore 6.
Stem 'l is provided with an enlarged head 9. A
handle member I 0 preferably of molded plastic
and in the form of a sleeve is rotatably mounted
over stein 1 and retained thereon by head 9. A
removable plug II is secured in the counterbored
end I2 of sleeve ID. By removing plug II, a
screw-driver may be employed to unscrew shaft
l from knurled member 5 so that all of the parts

it has been difficult to maintain between the stern
and the handle the exact degreefof friction which
would prevent the razor head from freely spin
ning or turning out of the desired position pre
paratory or during a shaving stroke and at the 20
same time avoid excessive friction between the
stem and handle which would prevent the razor
