' tain new and useful Improvements in Metal Wheels; of which the' following is a specimadef-from plates or rolled sections of metalv My present invention relates tothe construction vof -=meta'l wheels" in' which the. each other by spokes are all integral with meansof the `1"im"or -felly. The wheel 1s in contradistinction'to a cast wheel. y

The main object of the invention is to provide an exceedingly strong. wheel of comparatively light weight and one in which the hub around the spokes can be easily cleaned. The wheel is preferably formed from a rolled section such as an I b eam althoughit.v

may be formed from other forms of metal stock and when so formed, two wheels of any desired number of spokes may be secured from a single length of I beam whil'e'at the same time a wheel of great strength is attained, as, according to this invention, the spokes' are brought together in the hub and forni with the hub a truss construction.

construction of metal Wheel as hereinafter more particularly ydescribed and then vspecified in the. claims.
