Application September 12, 1945, Serial No. 615,857
12 Claims. (o1. 22a-_75)
This invention relates to stretchers for socks
and stockings, to be used in preserving the size
and shape of a sock or stocking while it is drying
after having been washed.
An object of the invention is to provide a sock
or stocking stretcher arranged to operate in a
novel and extremely simple manner.

as the sock is being slipped on to the form. The
shoulder 22' may also serve as a stop to limit
the retractingmovement of the leg member I2
by engagement of the edge 2I thereagainst.
The foot member I2 and leg member I3 are
urged apart by a screwjack comprising a screw
shaft 23 threaded through a threaded bushing
which is pressed into a counterbore 25’in"the'
outer extremity of the hole 20. The vscrevv shaftv
23 extends into the hole 20. At its outer end, the
screw shaft 23 has an annular flange 26 and a
pair of bearing surfaces 21, 28 disposed at either

ends of the trunnions 39 are flattened as at 48.
When the clamps are in their closed positions,
the cylindrical surfaces of the trunnions 39 are
in engagement with the flats 41 of the screw 46,
and the clamps are held snugly in the channels
4I by the tension of the springs 43, tending to
uncoil these springs.
With the ñats 48 of a clamp yoke 38 engaged
against the flats 41 of the screw 46, the yoke
will be held vin the outstanding position of the
upper yoke shown in Fig. 4. This position is also
indicated in Fig. 8, in broken lines. The flats
are heldin engagement with each other by the
