Wheels and wheeling; an indispensable handbook for cyclists, with over two hundred illustrations . Englefield Tricycle. vided with a bevel or crown wheel at the bottom, gear-ing with a similar one on the end of the pinion levers, too, are drawn up and down by a cord orstrap passing over a pulley fixed on the frame. A peculiar tensioned wheel frame is used on theEuclidia Safety. It consists of two half-tubes form-ing a sort of oval, running from the two extremities ofthe ball head, and carrying on their way the bearingsand seat grip. These are braced together by a num-ber of light spokes passing right across the frame, the PECULIAR CYCLES. 161 hub being no longer used. It makes a wonderfullystrong and exceedingly light frame. An objection to the Kangaroo type of Safety, withits two chains, having been the very wide tread—thehorizontal distance between the centers of the pedals,or rather between the planes in which the pedals.

The Excelsior Narrow Tread Wheel is especiallydesigned for dwarf bicycles. The usual hub, with itsflanges, is absent, and from the center of the axle fivestout tubes depart for about a foot, when their endsare crossed by short T pieces projecting about an inchon either side. These T pieces support two invertedfelloes or rings of rim steel, having their convex sur-faces on the outside instead of, as when used for their 162 WHEELS AND WHEELING. legitimate purpose, inside. From these rims spokesdepart in the usual way to the rims of the wheelproper, which hold the rubbers. This makes an ex-ceedingly strong wheel, though possibly a pound or soheavier than usual; the gain is in the width of tread,for the chain wheels and bearings, both upper andlower, are carried within the recess thus formed in thewheel, and the width of tread therefore is no more, if,indeed,
