1 the operator can manually adjust the ropes 2 a and 2 b respectively to conform the tilt of the swing seat 1 to conform with the bias of the concavity 4 when the operator enters the machine 20 beneath conveyor 9 or places his or her arms therein an osha approved e stop system 11 would be activated to deactivate the conveyor system 9 as well as the bed positioning unit 10 such safety systems are well known in virtually all manufacturing systems and need no further elaboration for purposes of explaining the present invention once the operator has removed himself or herself from the machine and outside the conveyor system 9 the machine can be energized to move swing 1 in direction of the arrow labeled flow this is accomplished by conveyor 9 and bed system 10 which simultaneously move the swing to a second position beneath piston cylinder 7 once the swing 1 and the bed 3 are in the second position beneath piston cylinder 7 the contact portion 6 swings from 45 u00b0 to 0 u00b0 as depicted in fig1 so that the contact portion aligns with the bottom of the swing seat 1 once the contact portion 6 is in position 0 u00b0 from the axis of the piston cylinder 7 piston cylinder 7 automatically operates to push the contact portion against the bottom of swing seat 1 the piston drives the contact portion so as to force seat 1 closely into concavity 4 conforming the seat bias therewith the force of the piston stroke moves bed 3 vertically downwards this movement is facilitated by a flexing mechanism 5 which can be constituted by a.
