site'nted Be it known that l, Wineries. B. Coons, a citizen. of the United States, i'esirlingin Jen- 'kini-own, Pei'insylvanio, have invented ceritem lmprm'enien ts in Mov his ioint (hoesinns, of which the followin My invention relates to that way crossings inwhich movable point reiis are used so-thet each treclc when the points are set will' be unbroken. I

Y The 'ob'ect of my present invention is to provide t e point rails with a herd metal point of special construction which. will be more substantlgil than the ordinary points used andwluohcan be firmly secured to the ,point rails. In the accompanying drenhngs: Figure 1,
