Inventor Gail L. Wheeler WW I Patented May 17, 1949 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to new and useful improvements in skis and the primary object of the present invention is to provide a ski the sliding surface of which is provided with a plurality of fibers that strengthen the ski and eliminate the normal tendency of the ski to split or break.

Another important object of the present invention is to provide a sliding surface for skis that is quickly and readil applied to the lower surface of a ski by the use of an adhesive compound such as glue.

A further object of the present invention is to provide a ski that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purpose for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of a ski constructed in accordance with the present invention;

Figure 2 is a top plan view of Figure 1;

Figure 3 is an enlarged fragmentary side elevational view of a portion of the present ski; and

Figure 4 is a transverse vertical sectional view taken substantially on the plane of section line 44 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed the preferred embodiment of the present invention, the numeral Ill represents the present ski generally of any suitable length, Width, shape or design. This ski preferably comprises a plurality of juXtapositioned layers of fibrous or wooden material l2 which are bonded together by means of a suitable resin glue. Also bonded by the use of resin glue to the outer face of the lower layer of material I 2, is a layer of fiber glass H which is similar in shape to the aforementioned layers l2.

Obviously, by applying the fibre glass layer to the ski structure, the necessity of steel edges or the like to strengthen the structure will be eliminated. Then too, the normal tendency of a ski to split, separate, or break, resulting from use or from drying out will be greatly reduced because of the fact that the flexibility of the fibre glass is less than the flexibility of the wooden layers I2, but the tensile strength of the fibre glass covering is much greater than that of the wooden layers, thereby insuring greater strength and a longer useful life to the ski. As a result of the application of the fibre glass layer, the expansion or contraction of the wooden layers !2 will be greatly reduced. It should be noted, that the fibre glass to be used may be a heavy gauge woven cloth or single glass fibres that are secured to the outer face of the lower layer of material l2 in any desired number of layers to make the ski as strong as required.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detail description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

l. A ski comprising a plurality of superposed layers of material, the lower layer of which consists of fiber glass, and means for bonding said layers together.

2. A ski comprising a plurality of juxta-positioned similarly shaped layers of material, the lower layer of which consists of fiber glass, and means for bonding said layers together.
