52.341. Spiral Wheel with Toothed Wheel, Figure 



The two axes are perpendicular to each other and intersect (without meeting one another). 



52.342. Counting Mechanism with Differential Wheels, Figure 



52.343. Reversing Gear with Spur Wheels 



52.344. Differential Epicycloidal Gear with Spur Wheels, Figure, for the addition and 

 subtraction of two rotary motions 



The resultant motion can be determined with the aid of a graduation and pointer. 



52.345. Simple Epicycloidal Gear with 2 wheels, for simultaneous rotation of the body about 

 two parallel axes, for proving that this rotation is equivalent to the rolling motion of 

 a cylinder on the jacket of a fixed cylinder 



52,340. Cycloidal Gear with Bevel Wheels (Taudin-Chabot's), Figure, quite tree from 

 iron parts 



52.347. Lahire Guides, Figure, for versed sine motion 



52.348. Guides with 2 Cranks, coupled with each other by congruent toothed wheels . 



52.349. Planet Wheels (Watt's), Figure 



52.350. - - i d c in, with counterpoise and fly-wheel 



52,351. Rack Motion, Guided Plate with groove, Toothed Wheel and Endless Rack; a toothed 

 piston with movable axis which engages alternately in both sides of the ruck, for con- 

 verting a continuous rotary motion into a uniform reciprocating motion 



rc'..';.")2. Rack Motion, partially Toothed Wheel and double Toothed Rack in slotted guide, for 

 reciprocating motion
