LEVER-GEAR MECHANISM FOR ADJUSTING THE POSITION OF A RECIPROCATING SLIDE WHILE THE DEVICE IS RUNNING

Click to enlargeClick to enlarge Description

Rotation of gear 1 about fixed axis A is transmitted through gear 2 to gear 3 which rotates about axis B. Crank 4 is rigidly attached to gear 3 and its roll a slides along groove b in slide 5, thereby reciprocating the slide. The position of slide 5, i.e. the positions of its right- and left-hand points of reversal can be changed without stopping the device by turning handwheel 6. This turns feedscrew c in nut d, cast integral with slide 7, moving the slide together with axis B of gear 3 and crank 4 to the right or left. Links 8 and 9 keep gears 1, 2 and 3 in mesh when the distance between axes A and B is changed.
