Wheels and wheeling; an indispensable handbook for cyclists, with over two hundred illustrations . Raglan Spring Wheel. and which being a perfect fit render any side-shake ofthe wheel impossible. A point worthy of note is thatthe springs are easily replaced by weaker or strongerones as may be required, thus insuring riders of differ-ent weights being equally well suited. The Raglan spring wheel is claimed to be anentirely novel method of reducing vibration. Thespokes are screwed into flanges somewhat larger indiameter than the hubs, and to these flanges are fixed ANTI-VIBRATION DEVICES. 219 four special springs, which hold the hub and conse-quently support the weight of rider. These springsare so arranged as to be capable of yielding in everypossible direction to any shock which may be causedby the unevenness of the road, with the natural resultthat such shock or jar is entirely absorbed. The Raleigh has a spring front fork arrangementin common with the Humber, and the same device isused on the Freeman Safety. In front of the main. Raleigh Spring Fork. sleeve steering socket there is a smaller sleeve case,which receives a guide; a short, upright pillar abovea lug projecting forward from the fork tops. A con-siderable proportion of the weight rests on springswithin the sleeve, which permits the pilot wheel togive way on meeting an obstacle without the rigidshock being communicated to the rider. A pattern of the Rival is fitted with a spring frame 220 WHEELS AND WHEELING. which is the only practical spring frame to which noobjection can be raised. It possesses the great advan-tage of being adjustable as regards tension. In thismost important respect it stands alone. This springframe, for lessening vibration, is the best device thathas been put on the market up to the present is as superior to any other device for lesseningvibration as the modern bicycle is to the old bone-shaker/ A rider of our spring frame Rival maystrike and run over a brick, and will hardly
