CATALOG OF THE CYCLE COLLECTION 35 



Colombia, Panama, Costa Rica, Nicaragua, Honduras, El Salvador, 

 Guatemala, Mexico, the Mississippi Valley, and Ontario, Canada, lie 

 reached New York City on June 2, five months later. It is estimated 

 that about 8,000 miles were covered during the trip. Subsequently, 

 Mr. Zabala pedaled the bicycle to Washington, where the machine was 

 presented by him to the National Museum. 



The Raleigh bicycle, made in Nottingham, England, is a well- 

 known machine. The lightweight, tubular frame of this example is 

 of the modern diamond type and is supported on two Dunlop metal- 

 rimmed wheels, with 32 tangentially laced steel spokes in the front 

 wheel and 40 in the rear. Each wheel runs on a pair of ball bearings, 

 an oil hole being provided in each hub for lubrication. Large wing 

 nuts are provided on each wheel axle to facilitate the removal of the 

 wheels. The tires, 26 by I14 inches in size, are equipped with inner 

 tubes. 



The fork, also of lightweight tubular construction, is mounted on a 

 pair of ball bearings, while the curved handle bars are made of tubu- 

 lar aluminum and are provided with rubber grips. 



The sprockets and Perry roller chain are on the right side of the 

 frame. The 46-tooth driving sprocket is mounted on a 3-piece crank 

 assembly supported in two ball bearings in the crank hanger. An 

 oil hole in the crank hanger is for lubrication of these bearings. The 

 61/^-inch crank arms are detachable from the center section of the 

 crank assembly, but are not adjustable. A ball-bearing-mounted, 

 all-metal pedal with a metal toe clip is fitted to each crank arm. 

 Attached to the rear wheel is a 3-gear, compound sprocket, made by 

 Cyclo, of Birmingham, England, containing 16, 20, and 24 teeth, 

 respectively, in its three gear sections. The three sections turn as a 

 unit with respect to the wheel, and contain an overrunning clutch 

 between the hub of the unit and the hub of the wheel so as to permit 

 coasting. In use, the chain is engaged with one of the three gear 

 sections, depending on the terrain to be covered. Changing is accom- 

 plished by loosening the wing nuts of the rear axle, placing the chain 

 over the gear section desired, adjusting the chain tension by moving 

 the wheel and axle within slots provided at the rear of the frame, 

 and tightening the wing nuts. Another 16-tooth gear is rigidly 

 attached to the other side of the wheel. By removing the wheel and 

 turning it around in the frame, this gear, which allows no coasting, can 

 be used. 



Front and rear brakes are provided, and each consists of a pair of 

 rubber-faced, metal shoes which clamp against the metal rim of its 

 wheel. Each pair of shoes is controlled by a cable and hand lever 

 attached to the handle bars, the right lever for the front wheel, and
