SCIENTIFIC MISCELLANY. 



RECENTLY PATENTED IMPROVEMENTS. 



J. C. HIGDON, M. E., KANSAS CITY, MO. 



Combined Cuff-Holder and Sleeve-Support. — This invention relates to 

 that class of devices in which the cuff is supported by spring clamping-jaws, and 

 it consists of an S-shaped strip of metal that is so combined with a suitable pin 

 as to be adapted for fixture within a coat-sleeve, where, by reason of its spring- 

 jaws it will hold the cufif securely in place. 



By dispensing with the pin, however, the strip of metal becomes simply a 

 support for the wristlet of the sleeve, and it is applied by placin_g it upon the edge 

 of the cuff, in which position it is held by reason of its inherent spring power. 

 Now upon the entrance of the descending wristlet within the cufif, it comes in 

 contact with the inwardly-projecting arm of the instrument and is thereby pre- 

 vented from falling so low as to be exhibited upon the wrist. 



In construction, a suitable piece of metal being provided, it is bent at one- 

 third its length or doubled toward its main position to form the two clamping- 

 arms and in an opposite direction to form the supporting-arm. The pin may 

 then be, or may not be, attached as desired. 



Electrical Game-Indicator for Pool Tables. — This improvement pro- 

 vides an efificient indicator wheneby the person in charge of a number of tables is
