SKI.

Application filed February 6, 1926. Serial No. 86,548.

My invention relates to improvements in skis, and consists in the combinations, constructions and arrangements herein described and claimed:

An object of the. invention is the provision of a ski which affords facilities for engagement with a surface on which the ski rests to prevent the ski from sliding backward on the supporting surface without interfering with the forward movementof the ski on the supporting surface.

A further object of the invention is the provision of a ski of the character described having means for releasably holding the retrograde movement preventing means of the device out of engagement with the sup porting surface when desired.

Other objects and advantages of the invention will be apparent from the following description, considered in conjunction with the accompanying drawings, in which Figure 1 is a side elevation of a ski embodying the invention,

Figure 2 is a relatively enlarged plan view of the rearward end portion of the blade of the ski and of the means for pre venting retrograde movement of the ski,

Figure 3 is a side elevation of the structnl'e exhibited in Figure 2.

In Fig. 1, I show a ski having a blade or body 1 of ordinary construction equipped with the usual means, as at 2, for securing the ski blade to the foot of the wearer.

It is desirable that the ski blade shall be held against any appreciable rearward sliding movement on a supporting surface, particularly when the wearer of a pair of the skis is ascending an incline or hill. To this end, the invention provides an anti-sliding or holding plate 3 which is formed with spaced aligned sleeve portions 4 at its for ward end adapted to be placed in alignment with sleeve portions 5 which are formed at the rearward end of an attaching plate 6 which is secured by screws 7 or like fastening devices on the rearward end portion of the blade 1 of the ski. A pintle 8 extends through the aligned sleeves 4, and 5 and may be retained against accidental displacement in any suitable manner as by having the ends thereof upset, as shown. The antislipping plate 3 and the attachingplate (3 thereby form leaves of a hinge and the attaching plate 6 preferably is secured on the ski blade 1 so that the sleeve portions of the attaching plates 6 will extend slightly beyond the rearward end of the ski blade. Certain adjacent sleeves 4 and 5 of the respective plates 3 and 6 are spaced to provide clearance for a coiled torsion spring 9 which encircles a portion of the pintle 8. One end portion of the torsion spring 9 extends on the upper face on the anti-slipping plate 3 and is bent laterally adjacent to its extremity as indicated at 10 to extend through a transverse eye or opening 11 in a bracket 12 which is secured to the anti-slip ping plate 3 on the upper surface of the latter by screws 13 or like fastening device, the extreme end portion of the rearwardly extending portion of thetorsion spring being bent forward as at 1 1 to prevent accidental displacement of the rearward end portion of the torsoin spring from the eye of the bracket 12. The other end portion of the torsion spring extends forward on the attaching plate 6 and is bent laterally at 15 to extend through a transverse eye 16 in a bracket 17 which is secured to the attachment plate 6 on the latter by screws vl8. The forwardly extending end portion of the torsion spring is bent rearwardly at its extremity, as at 19, to prevent displacement of the forward end portion of the torsion spring, from position on the attach ing plate 6.

The anti-slipping plate 3 is an elongated member having the side edges of the rearward end portion thereof curved convexly to converge together at a point which is located in the longitudinal median line of the plate 3. A relatively sharp point indicated at 20 thus is produced at the juncture of the side edges of the plate 3 with each other at the rearward end of the plate 3.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The torsion spring 9 will act to swing the antislipping plate 3 downwardly from the plane of the attaching plate 6 and retrograde slipping of the ski blade on a support-ing surface will be practically prevented by reason of the engagement of the rearward end of the plate 3 with the supporting surface. The pointed rearward end of the plate 3 will bite into the supporting surface and will effectually prevent the ski blade from slipping backward on the supporting surface. This is of particular benefit when'the wearer of a pair of the skis is climbing an inclined surface, such as a ski slideway. When desired,

the anti-slipping plate 3 may be held out of contact with the supporting surface and close to the upper surface of the ski blade. This is done by means of a pivoted retaining member or button 21 which is carried in slightly spaced relation to the ski blade on the upper face of the latter and is adapted to be turned to and from position to overlap the adjacent end portion of the plate 3 when the latter has been swung upwardly and forwardly from the position shown in the drawings to position to be superimposed upon the rearward end portion of the skipermit the plate 3 to swing downwardly to a relatively great angle to the plane of the ski blade and. instant engagement of the pointed rearward end of the plate 3 with the supporting surface thus will be assured and V rearward slipping movement of the ski blade will be instantly prevented.

Obviously, the invention is susceptible of embodiment in forms other than that which spring disposed on said pintle between said spaced adjacent sleeve portions, the end portions of said spring extending. in opposite directions from said pintle and the extreme end portions of the spring being turned? laterally and bent toward said pintle, means embracing one laterally turned end portionv of the spring and securing one end of said torsion spring on theattachrng plate, means.

embracing the other laterally turned end portion of the spring and securlng the other end ofsaid torsion spring on said anti-slipping plate and a pivoted button carried by said ski for releasably holding said antislipping plate superimposed upon said: ski

when said anti-slipping plate has been swung upwardly and forwardly about the axis of said pintle to superimposed position on said ski.
