摘要 |
A drive shaft 40 extends through a ram 42. The ram can be driven up and down by rotating a screw shaft 35. The ram carries with it a motor 44 which drives a pulley 36 connected to the top of the shaft 40 for rotating that shaft 40. The ram 42 can be rotated upon operation of a motor 60 which drives a worm 62 to engage a worm wheel 64 which surrounds the ram 42 and is fast therewith. |
