Abstract

930,727. Watches. E. H. C. DE CARVALHO. July 28, 1961, No. 27546/61. Class 139. Two or more stopwatches 12, Figs. 1 and 3, are so located in a holder 1 that they can be individually operated by corresponding pushbuttons 21 and can be simultaneously operated by a spring-loaded crossbar actuable by a pushbutton 30 through a linkage 31, 32, 33. A counter 17 is also located in the holder 1 and is operated by the cross bar 23 and by a push-button 22 and can be zeroized by rotating a knob 19.
