Fletchers patent(316 of 1877) shows the side-cap bolts as continuous from cap to cap, andthis method is most generally employed. The Housing and Arrangement of the Rollers.—There are many designswhich, while retaining the isosceles triangle arrangement of the rollers,depart from the horizontal side gap or Buchanan type of housing. Walker(patent i486 of i860) cast the housing so that the rollers rested on surfacesperpendicular to the line joining the centres of the top roller and of a lowerroller. This arrangement, which prevents any horizontal movement of th
