">L',:;.Vi. Connecting Rod with Guides, Toothed Wheel and Toothed Racks, for doubling the stroke 

 of alternating motion 



2,354. Interference Mechanism, for the addition and subtraction of 2 oscillating versed sine 



motions, for explaining interference phenomena 



Two toothed wheels, one having 66 and the other 67 teeth, are mounted on parallel axes and 

 fitted with cranks and connecting rods joined up to the same beam. The latter is fixed to the recti- 

 lineally reciprocating rod. 



32,355. Masked Rotating Slot and Crank 



This mechanism corresponds in its action to the rotating slot and crank No. 52,255; the motion 

 is, however, transmitted by toothed wheels instead of by a slot and crank. 



>2,3r>f>. Toothed Gear for Oscillating Movement, Curved Back and partially Toothed Wheel 

 ">2.357. Mangle Wheel, Figure, for reciprocal rotation at constant speed 



>2,35H. Intermittent Wheel with External and Internal Teeth, for reciprocal rotation at dif- 

 ferent speeds; the teeth traverse each other in two places by small semi-circles. . . 



>L.'..',5!i. Reversing Gear, with Bevel Wheels 



)2,36<>. Differential Epicycloidal Gear with Bevel Wheels, F i g u r e, for the addition and 

 subtraction of two rotary motions 



The resultant motion can be followed by a pointer rotating in front of a circular graduation.
