ing- is performed by tightening-the nut 13, where‘
My‘ invention relates to means for preserving
the shape of skis when they are not in use,
especially in the warm season when they are apt
to‘ warp-out of shape, and the object of my in
5 vention is to provide a simple and cheap yet ef
fective and universal device for said purpose.
In the accompanying drawing, Fig. 1 is an
edge view of a pair of skis with the form-re
taining device applied to same. Fig. 2 is a side
10- view‘ on an enlarged scale of the pair of skis,
the middle portion of the skis being broken away.
Fig; 3 is an edge view also on an enlarged scale
of the'front curve of the one ski.
Referring to the drawing, l designates the
15‘ skis placed with the running surfaces turned to
wards each other.
Placed at each front curve
of the- ski is an attachment member 2, which is
preferably adjustable, so as to be capable of be
ing moved to and attached at different places
20 of the front curve and which may consist of a
leather strap reinforced by means of a flexible
steel band or the like and provided with ordinary
locking means. In the embodiment shown the
said strap is provided with a small slip-roller 3.
25 Provided transversely between the skis approxi
mately at the root of the front curves is a slid
able guide member 4 provided at its ends with
small slip-rollers 5. Placed about the said latter
rollers 5 as well as about the rollers 3 of the
30 attachment members 2 is an endless cord 6, for
instance a steel-wire, chain or the like. Secured
to the middle point of the guide member 4 is a
second cord 1, which may also consist of a steel
wire, chain or the like and which, through the
35 interconnection of links 8 and a hook 9 for vary
ing the length of the cord, extends to the rear
ends of the skis. At this end the cord 1 is con
nected to a screw II), which passes freely through
a sleeve member ll placed between the end por
40 tions of the skis and adapted to bear against
by‘ the running parts‘ proper of ‘the skis as well
as the front? curves will be bent and held in the
desired bent form as long as the stretching de
vice’ is applied.
By connecting. the attachment?
members and the guide member through an end
less-‘cord, as shown, an equalizingrof‘ the stretch
ing power on both of the front curves will‘be at
tained.
If, for instance, the bending of‘ the running’ 10
parts of the skis is to be limited and that of the
front curves increased, a strap I5‘ or any other
suitable means may be applied around said parts
at the usual steps, as shown in Fig. 1.
If, on the other hand, the bending of the front
curves is to be limited, the attachment members
Z‘are applied‘ nearer the roots ofthefront curves»;
If the one front curve needs to be bent more
than the other, the attachment members 2 are
placed at different distances from their roots.
If the one running part needs to be bent more
than the other, the strap IE or the like can be
applied solely around the latter running part
and the cord 1, whereby the former running part
obtains a greater freeness to be bent.
What I claim as new and desire to secure by
Letters Patent of the United States of America
1s:—
1. A ski~form protector comprising a clamping
member adapted to be secured to the front curve
of the ski, a movable guide member adapted to
be placed transversely at or in proximity to the
root of said front curve, a cord between said
clamping member and said guide member, an
end support adapted to bear against the rear end 35
of the ski, a cord between the said guide member
and the said end support, and power amplifying
means for stretching said cords.
2. A ski-form protector comprising an adjust
able clamping member adapted to be secured to
the front curve of the ski, a movable member
the cavettos of the skis. The sleeve II is pro
vided with end supports 12 for the skis, which ' adapted to be placed transversely at or in prox
supports may be made to suit to the con?guration imity to the root of said front curve, a cord be
of the ends of the skis, i. e. to straight, acute tween said clamping member and said guide
member, an end support adapted to bear against 45
4.5 or curved ends, so as to obtain a safe support.
Screwed on the screw ill outside the supports I2 the rear end of the ski, a cord between the said
is a wing-nut [3. At its inner end the screw guide member and the said end support, and
I0 is provided with radial wings l4 adapted to power amplifying means for stretching said cords.
3. A ski-form protector for preserving the shape
enter into the cavettos of the skis, so as to pre
of a pair of skis placed with their running sur
50 vent turning of the screw when turning the nut
l3. After the nut has been screwed on, the screw faces facing each other comprising‘ a clamping
can be beaten down at its outer end, so that member for each of the front curves of the skis,
a movable guide member adapted to be placed
the nut cannot be removed and get lost.
After the stretching device has been applied transversely between the skis at or in proximity
to the root of said front curves, an endless cord 55
55 to the skis in the manner described, the stretch

slidably connected to said clamping members and
to the ends of said transverse guide member, an
end support adapted to bear against the rear
ends of the skis, a cord between the said guide
member and the said end support, and power
amplifying means for stretching said cords.
4. A ski-form protector for preserving the shape
ing member for each of the front curves of the
skis, a movable guide member adapted to be
placed transversely between the skis at or in
proximity to the root of said front curves, an
endless cord slidably connected to said clamping 5
members and to the ends of said transverse
guide member, an end support adapted to bear
of a pair of skis placed with their running sur
against the rear ends of the skis, a cord between
faces facing each other comprising an adjustable
the said guide member and the said end support,
and means for stretching said cords, said means
10 clamping member for each of the front curves
of the skis, a movable guide member adapted to
be placed transversely between the skis at or in
proximity to the root of said front curves, an
endless cord slidably connected to said clamping
members and to the ends of said transverse guide
member, an end support adapted to bear against
the rear ends of the skis, a cord between the said
guide member and the said end support, and
power amplifying means for stretching said cords.
5. A ski-form-protector for preserving the
shape of a pair of skis placed with their running
surfaces facing each other comprising a clamp
ing member for each of the front curves of the
skis, a movable guide member adapted to be
placed transversely between the skis at or in prox
imity to the root of said front curves, a slip
roller at each of said clamping members, a slip
roller at each end of said transverse guide mem
ber, an endless cord placed around all of said
slip-rollers, an end support adapted to bear
against the rear ends of the skis, a cord between
the said guide member and the said end sup
port, and power amplifying means for stretching
said cords.
6. A ski-form protector for preserving the
shape of a pair of skis placed with their running
surfaces facing each other comprising a clamp—
comprising a screw running freely through said
end support in the longitudinal direction of the
skis and having its inner end connected to said
latter cord and a nut at its outer end outside said
end support.
'7. A ski-form protector for preserving the
shape of a pair of skis placed with their running
surfaces facing each other comprising a clamping
member for each of the front curves of the skis,
a movable guide member adapted to be placed 20
transversely between the skis at or in proximity
to the root of said front curves, an endless cord
slidably connected to said clamping members and
to the ends of said transverse guide member, an
end support adapted to bear against the rear ends r‘
of the skis, a cord between the said guide mem
bers and the said end support, and means for
stretching said cords, said means comprising a
screw running freely through said end support
in the longitudinal direction of the skis and hav 30
ing its inner end connected to said latter cord
and a nut at its outer end outside said end sup
port and having further radial projections at its
inner end adapted to bear against the skis, so as
to prevent turning of the screw at the turning
of the nut. '
