This invention relates to new and useful improvements in traction increasing appliances for automobile and truck tires and more particularly to an anti-skid device which has as its principal object the provision of means to prevent skidding in a much more efiicient manner than is available with present-day appliances.
Another important object of the invention is to provide an anti-skid device for vehicle wheels which can be quickly applied and removed with equal facility.
Still another important object of the invention is to provide an anti-skid appliance for vehicle wheels which when applied and under operating conditions cannot damage the vehicle wheel.
Other objects and advantages of the invention will become apparent to the reader of the following specification.

Figure 11 is a fragmentary detailed sectional view showing how the anti-skid unit is attached to the fastening means.
Figure 12 is a fragmentary elevational and sectional View of the fastening annulus.
Referring to the drawings wherein like numerals designate like parts, it can be seen that the form of the invention disclosed in Figures 1 and 2 is especially adapted for truck wheels and other heavy duty use. This particular form of the invention consists of a substantially rectangular-shaped pressed metal sheet 5 having a transversely disposed trough 6 at its intermediate portion and end troughs l and 8, and obviously, additional troughs can be provided if desired.
Between the troughs and at the underside of the plate 5 are metal blocks or thick plates 9 and I8 suitably bonded to the plate 5 and these have a multiplicity of threaded recesses I I therein for the reception of the threaded shanks I 2 of calks l3 which rise above the plate 5.
Suitably bonded to the underside of each of the plates 9 and I0 is a resilient plate M which, of course, when the appliance is in use, bears against the tread of the wheel.
Disposed longitudinally in the trough 6 and suitably bonded to the plate 5 is a block I! of rubber, and blocks l8, l8 of rubber are disposed in the troughs l and 8 and have tail portions I!) which fit under the troughs 1 and 8, that is, between the bottom side of the troughs and the tire tread, or on the other hand, are provided with pockets into which the trough structures 1 and 8 are disposable. Under the trough 6 is a plate 20 of resilient material which bears against the tread of a tire when the device is in use.
Another form of calk is shown in Figure 6 wherein numeral 2| denotes a screw having a tapered head 22 and the numeral 23 denotes a calk head of tapered construction having a threaded recess for the reception of the screw 2|.
A third form of calk is shown in Figure 7 and denoted by numeral 24, this form being of U- shape and having its leg portion welded or otherwise secured to the plate 5 or extending through the plate 5 from the plates 9 and N). This form of calk has the same action as chain links as in anti-skid chains.
Another form of the invention is shown in Figures 8 and 9. In this form of the invention an elongated metal plate 25 is provided and as shown in the two views, is both transversely and longitudinally curved to conform with the curvatures of a wheel. This plate 25 has short downwardly disposed side flanges 2B culminating in ears 21 at the ends thereof, these ears having apertures 21 therein. The flanges 26 and ears 2'! are disposed at angles to avoid the side walls of a tire.
Figures 10, 11 and 12, show fastening means for attaching one or the other of the two forms of the invention to a wheel.
At the outboard and inboard side of the wheel generally referred to by numeral 35 is an annulus 36, split but being of suflicient length to have its ends overlapping as clearly shown in Figure 10. One of these overlapping ends has keyhole slots 31 which can receive a headed stud 38 projecting from the other end portion, and a swingable keeper 39 is provided On the end portion with the Keyhole slot to embrace the stud under the head thereof to prevent displacement thereof from a position fastening the overlapping "ends of the annulus together. 7
The inner edge portion of each of the annuli is notched as at 46 so as to define narrow portions 4! which can be spanned by the harness hitch 34, yet the notches serving to prevent circumferential movement of the hitches on the annuli.
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 for use on rubber tired wheels comprising an elongated plate adapted to be applied to the tread of a tire to extend length- Wise circumferentially thereof, said plate having bent portions forming a central transverse trough and a pair of transverse end troughs in said plate, a pair of rectangular blocks of rigid material underlying said plate between said end troughs and the intermediate troughs and bonded to said plate, said blocks having facings of resilient material for engaging said tire, an elongated member of resilient material fitted in said central trough, and a pair of elongated end members of resilient material fitted in said end troughs and extending around the ends of the plate under said end troughs, and means to attach the plate to a wheel.
2. An anti-skid device for use on rubber tired wheels comprising an elongated plate adapted to be applied to the tread of a tire to extend length wise circumferentially thereof, said plate having bent portions forming a central transverse trough and a pair of transverse end troughs in said plate, a pair of rectangular blocks of rigid material underlying said plate between said end troughs and the intermediate trough and bonded to said plate, said blocks having facings of resilient material for engaging said tire, an elongated member of resilient material fitted in said central trough, and a pair of elongated end members of resilient material fitted in said end troughs and extending around the ends of the plate under said end troughs, means to attach the plate to a wheel, and caulks threaded through said plate into said blocks.
