W. Haight, ofDayton, Ohio, has brought out the Hoagland noiseless car. SECTION OF NOISELESS CAR WHEEL wheel, which is made in two pieces. One piece of this wheelforms the center, which is provided with an exterior flange,and bearing surface. In this flange are cored bolt holes for14^4-in. bolts. The bearing surface is made on an incline ofl/i in. in 2 ins., which makes it possible to form a joint and getthe necessary pressure required from the bolts. The outerring or tire is provided with an inverted flange which hascored bolt holes to match the holes in the center part; it alsohas a bearing surface to meet the one on the inner part of the wheel. The flange on the center part is on the inside, projectingoutward. The tire flange is on the outside, projecting these two flanges is a space of about 1^4 ins.; in thisspace is the bearing surface. Between the two castings thereis sufficient room for a 3-16-in. paper packing. No parts of thetwo castings come in connection with one another; no boltholes are drilled, a
