To all (whom. it may co'rwem:

Be it known that I, VENDEL LszLLo B' KEFI, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented-,certain new and useful Improvements in Armors for-Automobile-lVheels, `of which the following is a specification.

'My invention relates to armors for'automobile wheels, and the invention consists in an armor made up of two series of plates mounted one upon the other and constructed and adapted to operate substantially as shown and described and particularly pointed out in the claim. In the accompanying drawings, Figure 1 1s a side elevation of a section of a wheel upon which my improved armor is shown in working position. Fig. 2 is a longitudinal section of two of said plates and Fig. 3 is a cross section thereof. Fig. 4 is a perspective view of one of the outer plates and Fig. 5 is a perspective view of one of the inner plates. f

The invention as thu's shown is an improvement upon the construction of armor shown and claimed in my patent issued June 16,1908, No. 891,830. In the said patent the plates are single and adapted to overlap at their ends, and are smooth internally and externally. They also are heaviest or deepest at their lniddle longitudinally and recessed transversely over one end each so as to lap the end of the next succeeding plate thereover and make a uniform outside or peripheral surface on the tread of the wheel. The present invention is made to overcome the objection to my patented armor in this, that if one of 'those plates become impaired it had to be thrown away and a new one be substituted in its entirety. This made the armor unduly expensive because I found that such injuries were quite frequent. Hence I conceived the idea of building an armor with a dual construction and in which there is a permanent inner plate A and an outer service plate B removably fixed thereon.l The latter is distinctly a road contact plate which wears out sooner or: later and is intended to be replaced when this occurs. To this end the said plate is proj'vided with transverse corrugations 2 which are deepest at the center and take the immedr ate exposure to the road. Said plates", like inner plates B, are of suitable metal, and

the outer plate lies upon the inner plate relatively as shown an'd is secured thereto by screws 3 or their equivalent. The outer plate overlaps the inner plate at one end and the inner plate projects beyond the outer plate at the other end in the same proportion, so that the outer plates will always .overlap the joints of the inner plates. or

`the two sets of plates will break the joints as shown. The inner plates are secured upon tire T by turnbuckle connections lv at leach side engaging with chains C at the side of the rim as shown.

The plate B is preferably made out of a piece of sheet steel bent 'substanially half round in cross sect-ion and adapted to lit4 snugly over tire tube T. Eaid plate therefore is of uniform thickness throughout and comparatively light in weight, while plate A is of suitable cast metal, preferably, though it might be struck up.from sheet metal vwith more or less pronounced ribs 2. The inner plates B also have na'rrow exposed edges 7 at each side extending outward beyond plates A and turnbuckles 4 are attached thereto, two for each side near the ends of said plates. It follows that a cornplete unitary part made according to my in-l `vention consists of two plates A and B fastened together and arranged in respect to cach other relatively as shown, one end of cach plate projecting beyondV the corref spending end of the other plate and said plates adapted to match with the next pair of plates at both ends as hereinbefore described. j

To facilitate traction purposes, especially in climbing hills, the transverse ribs 2 of plate A are preferably of ratchet like tooth formation as shown in crosssection in Fig. 2.

Plate B is preferably struck up outwardly to form an offsetv or recess b at the point where the pivoted connection of turn-buckle 4 is made, the object being to keep said connection out of Contact with the rubber tire and prevent wear and abrasion thereof.

IVith the use of this invention, tires as ordinarily constructed may be materially lightened and madeft'hinner especially at the tread portion thereof, and there is also a saving of power in driving a machine because of the excellentl tract-ion results to be obtained' by its use.

l'Vhat I claim is: j
