FIG. 1187*. 



1187 Pedometer or Watch for Recording and Measuring the distance travelled by 

 a Pedestrian. 



This little instrument is generally carried in the waistcoat pocket or in the 

 fob, or else attached to a belt or to a button ; the hook attached to the ring must 

 be so fastened to the slit of the pocket or elsewhere that the instrument be always 

 in a Vertical Position. 



It never requires any winding up, the first step of the Pedestrian sets the 

 works in motion ; they continue to act as long as he moves, and stop when he 

 stops. The dial is divided into twelve divisions, which represent so many Miles, 

 but can be adapted to record Kilometres or any other measure of distance. The 

 Pedometer is corrected by means of an adjusting screw, which is square -headed, so 

 as to be turned by a watchkey ; all that is necessary to do is to walk a mile, and then 

 observe the position of the index hand upon the dial ; the regulator is then turned 

 to the left for Slow, or to the right for Fast, until one division on the dial represents 

 exactly the measure of distance chosen, Mile or Kilometre, &c. This of course will 

 depend upon the length of stride of each individual, and must be regulated accord- 

 ingly. The dots between the figures represent Quarter miles. When about to 

 start, the Index Hand should be placed at Zero, by moving it either backwards or 

 forwards with the finger. If the Pedometer is not required to act, it should be 

 carried with the Pendant ring downwards. 



FIG. 1187 exhibits the dial or face of the Pedometer, and fig. 1187*, the interior 



and movement of the instrument. Price, in Stout Silver with case . 2 15

1188 Passometer or Step Measurer, is a similar sized instrument to the Pedometer, 

 arranged to record the number of paces or steps taken by the wearer. These are 

 indicated on the face of the instrument by a small circle (similar to the seconds 

 dial of an ordinary watch) up to 50, and then on the large dial by a series of 

 divisions, each equally 50 paces up to 2,500 ; the readings on the dial are continuous 

 as in the Pedometer. Price, in Stout Silver Case . .550 



1189 Chronograph. Without stopping the movement of the watch the long seconds' 

 hand of this instrument records on the Dial the interval between two given 

 events, with unfailing accuracy. Price, in Gold Case, 60 guineas ; Silver Case, 

 45 guineas ; or to go for two hours only, Gold, 20, Silver 12 12s.
