52.274. Cardanic Double Coupling, Figure, for the uniform transmission of motion at 

 any angle or on a parallel axis, "with degree graduation on the axes and on the base- 

 plate 



The two cross joints of this model are equally placed. The dissymmetry of the transmission 

 "t motion of the single cross joint is obviated by the use of the two equally placed cross joints when 

 tin- two external axes opposite the centre axes form the same angle either whether they form twice 

 this angle of inclination among themselves or whether they are parallel. 



52.275. Goubet's Coupling (Double Universal Coupling), Figure, with sleeve, for two 

 intersecting axes, with graduations and pointers 



The ratio of rotational speeds of the two axes is constant. 



512,1276. Clemens' Coupling, Figure, with ball and socket joints for two intersecting axes 

 The ratio of rotation of the two axes is constant.
