1 Claim. (Cl. 280—11.13)
This invention relates to skis and has for its
main object to provide a novel and e?icient de
vice to aid the user of such skis in climbing hills
or in general when ascending.
Another object of this invention .is to provide
a device as characterized hereinbefore which may
easily,‘ quickly and conveniently be put out of op‘
eration when the user of the skis is descending,
or proceeding on more or less level ground, while
lothe device will remain ready for a quick change
and in a position to be again useful in case an
ascending is necessary.
Other objects of this invention will be appar
ent as the speci?cation of the same proceeds, and
15 among others I may mention: to provide a device
of the character mentioned which will be simple
in construction, inexpensive to manufacture,
adapted to be applied to skis, as at present in use,
and to various sizes thereof without any extra
“mechanical changes therein, and Without weak
‘ ening the, skis.
I am aware of the fact that many attempts
have been made heretofore to aid skiers in as
cending, and for this purpose in some cases it
25. was proposed to treat the lower or running sur
faces of the skis with a special wax, or, leather,
pieces of fur, or other devices have been applied
to said running surfaces to increase the frictional
resistance. All these devices and means required
30 certain experience and skill, or they were awk
ward and cumbersome mechanical devices caus
ing a great amount of labor, trouble, and con
suming valuable time on ski voyages. This was
especially the case in such voyages in which al
35 ternately ascending and descending stretches
were included. The ?nal result was that the skier
either abandoned all such aids or was greatly
hindered through such devices in his travel.
I also am aware that various mechanical de
40 vices have been applied to skis for the purposes
mentioned hereinbefore, but it is a common
knowledge that their operation was very unsatis
factory, and they also were apt to cause trouble
and annoyance, and ultimately they were rather
45 a hindrance than an aid.
All these drawbacks of the older devices have
been eliminated by my device which is the sub
ject of the present invention, and my invention
enables a skier to apply on his skis, and at any
time and as often as he desires, and in a quick,
convenient and secure manner, a device which
will aid him in ascending even quite steep hills
with the least possible effort, and which device
55 after the ascent may again be in a similar easy
and quick manner put out of operation so as not
to obstruct the further travel.
My invention mainly ‘consists in .a grip- or
wedge member which may easily be applied un
derneath the running surface of the ski in- a
transverse direction thereto, and which at any
time may be as easily taken off from the same,
and which wedge or grip will be ‘of such a design
and height that it will provide a secure grip and
stopping action in all kinds and conditions of 10:
surface of snow.
The wedge or grip and its securing means are
of such construction that when it is desired to
put said grip out of operation the same may
easily and quickly be entirely taken off the ski 15:1
and carried in a bag or in a pocket of the skier,
or it may simply be secured on the upper surface
of the ski.
In the drawing forming a part of this speci?
cation and accompanying the same:
Fig. 1 is a side elevation of a ski to which my
invention has been applied;
Fig. 2 is a fragmentary side elevation of the
center portion of the ski shown in Fig. 1, on a
larger scale, showing my device applied thereon ‘25‘
in an operative position,
Fig. 3 is a similar side elevation showing my
device on the upper surface of the ski in an in
operative position, and
Fig. 4 is a fragmentary plan view of the center 30
portion of the ski on- a larger scale showing my
device applied thereto, the wedge or grip por
tion thereof having been removed.
Referring now to the drawing more closely by
characters of reference, the numeral l0 indi-.
cates a ski on the upper surface whereof is ap
plied in about the center 'of the same a plate
member forming a generally semi-circular sleeve
ll transversely to the ski l0, and being secured
thereon in any convenient manner as by the 40
screws l2.
Journaled in the sleeve II is an vupper trans
verse member or branch l3 of a rectangular
frame, generally indicated by the numeral “I,
having righthanded and lefthanded side mem- 45
here l5 and I6, respectively, and a lower trans
verse member l'l.
Normally the frame I4 is in the position indi
cated in Figs. 1 and 2, its lower member I‘! be
ing underneath the running surface of the ski 50
at a desired distance thereunder and transverse
ly thereto, and on said lower transverse member
I‘! is applied the operating element proper of my
device being in the form of a grip or Wedge l9,
preferably having a pointed gripping edge 20, a 55
base surface 2 I, a convex front surface 22, and a
concave rear surface 23, the two surfaces being
in the angular relation and relative positions and
proportions shown in the ?gures.
The left hand side member I6 is pivotally con
nected to the lower cross memberv H as indicated
at 24, and said member I6 is provided with a
preferably rectangular slot or opening 25 which
is adapted to receive a similarly ?attened outer
10 end 26 ofrthe upper transverse member I3. For
better securing said ?attened end 26 in said slot
25 a nose or projection 21 may be formed on the
termination of said ?attened end 26, as‘shown in
Fig. 4. The outer end of the left side member
15 I6 may be screw threaded as at 28, and engaged
by a wing nut 29.
wedge members may be carried in a pocket or in
any other appropriate manner.
While I have shown and described a preferred
embodiment of my device it will be understood
that changes and. variations may be resorted to in
the details of the construction and application
thereof, and I desire to reserve my rights to such
changes and variations as are within the spirit of
this speci?cation and the scope of the claim here
unto appended.
Such changes may be resorted to in the means
for arranging and securing the grip member
