Mechanism to Generate Two Different Phase Reciprocations by One Cylinder

      Disclosed is a mechanism for realizing two-phase
reciprocations by one cylinder.

      Fig. 1 shows the present mechanism.  Shaft 8 is attached to rod
4 of cylinder 2.  The lower end of the shaft 8 is inserted into
coupling 24.  Spring 22 is provided between the flange at the lower
end of the shaft 8 and nut 20 which is screw-clamped to the coupling
24.  Stopper 12 is mounted between the coupling 24 and slider 18.
Spring 16 is provided between the slider 18 and spring stopper 14.
When the shaft 8 is reciprocated by the cylinder 2, the coupling 24
and slider 18 also reciprocate with different phases.

      Fig. 2 shows the operation.
Condition 1. - The shaft 8 is at its upper dead point.
     The coupling 24 is pressed against the stopper 12.  The springs
16 and 22 are in compressed state.  The slider 18 is at its highest
position due to pushing up by shoulder 10 of the shaft 8.
Condition 2. - The shaft 8 starts to move downwawrd.
     The coupling 24 is still urged upward agaist the stopper 12 by
the spring 22 and stays at its highest position.  The slider 18
starts to move down along with the shaft 8.
Condition 3. - The shaft 8 continues to move downward.
     The coupling 24 still stays at the highest position. The slider
18 engages with the stopper 12 and stops moving down.
Condition 4. - The shaft 8 continues to move downward.
     The coupling 24 starts t...
