62.893. Speed Counter with 2 spindles for working in both directions, Figure, counting 

 from 5000, nickelled, with three different attachments for the spindles, in case . 



The first attachment is intended for centre-point shafts, the second for tapering shafts. The 

 third attachment is used when neither centre-point nor taper is available or if the end of the shaft is 

 not accessible. It is formed by a disc 24 mm diameter which is pressed on to the outer periphery 

 of the shaft to be measured. 



62.894. Hand Tachometer with spring axis for automatically setting the ranges, Figure, 

 for 100 4000 revs., for dynamos and shafting, with attachment, in case, 60 mm scale 

 diameter , .... 



The tachometer has three different ranges: 100 400, 3001200, 1000 4000. In this new in- 

 strument, provided with spring axis, the trouble of setting the range and transferring the cam to other 

 axes is obviated. It is also impossible to damage the tachometer by over-running the pendulum shaft. 



62,895. --idem, for 300 12 000 revs., with attachments, in case 

 The ranges are: 3001200, 9003600, 300012000.
