4 Claims.

This invention appertains to new and useful improvements in anti-skid devices for vehicle wheels.

The principal object of the present invention is to provide an anti-skid device which can be readily attached to automobile tires in order to increase traction in snow and on ice and to prevent skidding on wet and slippery pavements.

Another important object of the invention is to provide an anti-skid device of the character stated which is constructed in a simple and inexpensive manner, and which can be taken apart for the purpose of repair and replacement of parts when desired.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a side elevational view of the device.

Fig. 2 is a top plan view.

Fig. 3 is a fragmentary bottom plan view.

Fig. 4 is a fragmentary perspective view showing the band with the rubber unit thereon.

Fig. 5 is a perspective view showing the cap plate and one of the bridge pieces.

Fig. 6 is a perspective view of one of the transverse calks.

Fig. 7 is a sectional view on line '!1 of Fig. 1.

Fig. 8 is a perspective view of the locking key.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the elongated band which may be of reinforced fabric, leather, or any other suitable material, and this is provided at its ends with barrel-like constructions 6 through which tie members can be disposed.

As is shown in Fig. 4, the intermediate portion of this band 5 is provided with cut away portions 1 at each of its longitudinal edge portions as is the neck portion 8 of the calk assembly generally referred to by numeral 9. This assembly consists of the two rubber blocks l0l0 connected by the neck 8 which has the reduced portion coincident with the cut away portions 7 of the band 5.

Numeral H represents a cap structure having the depending side flanges l2. This cap H is provided with longitudinal slots I3 therein which extend over the reduced portion of the neck 8 and the cut-away portion of the band 5. Rectangular shaped calks It provided with depending flange members [5 are pro vided, and these flange members l5 depend thru the slots 13 and reduced portion of the neck 8 as well as through the cut away portion I of the band 5, and the lower portions of the inside surfaces of these flanges l5 are provided with longitudinally extending grooves l6 for receiving the longitudinal edge portion of the lock plate l7. When the flanges l5 are depending through the cap II in the manner shown in Fig. '7, the transversely arcuate looking plate I? can be inserted between the lower portions of the flanges l5 and the edge portions of the plate engaged into the grooves it. This locking plate I! being of ductile material, can then be fed upwardly so that the edge portions of the plate will entirely engage into the grooves It, thus preventing the calks l4 from being displaced from the cap H.

An opening 18 is provided down through the cap H, neck 8 and band 1, so that when desired, a tool can be inserted through the assembly and punched against the key plate I I to remove the same from its locking position shown in Fig. 7, that is when repair or replacement of parts is desired.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

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

1. An anti-skid device comprising a band, a cap secured to the intermediate portion of the band, said band having its longitudinal edge portions reduced at the caps, said cap being provided with longitudinal slots therein, overlying the cut away portions of the bands, calk members pro vided with depending flanges disposed through the slots and cut away portions of the band, and a locking key between the said flanges at a point underlying the band.

2. An anti-skid device comprising a band, a cap secured to the intermediate portion of the band, said band having its longitudinal edge portions reduced at the caps, said cap being provided with longitudinal slots therein, overlying the cut away portions of the bands, calk members provided with depending flanges disposed through the slots and cut away portions of the band, a locking key between the said flanges at a point underlying the band, said locking key consisting of a ductile plate primarily of arcuate shape, said flanges being provided with grooves on their opposed faces to receive the plate when it is flattened out against the lower side of the band.

3. An anti-skid device comprising a band, a cap secured: to the intermediate portion of the band, said band having its longitudinal edge portions reduced at the caps, said caps being provided with longitudinal slots therein, overlying the cut away portions of the bands, calk members provided with depending flanges disposed through the slots and cut away portions of the band, a locking key between the said flanges at a point underlying the band, said locking key consisting of a ductile plate primarily of arcuate shape, said flanges being provided with grooves on their opposed faces to receive the plate when it is flattened out against the lower side of the band, said caps and band being provided with registering openings through which an instrument can be disposed for displacing the plate from the flanges.

4. An anti-skid device comprising a band, a cap secured to the intermediate portion of the band, said band having its longitudinal edge portions reduced at the caps, said caps being provided with longitudinal slots therein, overlying the cut away portions of the bands, calk members provided with depending flanges disposed through the slots and cut away portions of the band, a locking key between said flanges at a point underlying the band, and a calk assembly comprising a pair of calk members, a neck connecting the calk members, said neck being disposed between the cap and the band, said calk members being disposed beyond the ends of the cap.
