These drivingbelts arc looped under idlers around looseclutch pulleys on short horizontal shaftscarried on each spindle saddle, as partlyshown in Fig. 3. and these horizontalshafts have each a hand-lever-operatedclutch on a feather between the two belt-driven pulleys; all so arranged that by LOCOMOTIVE ENGINEERING. 669. journals on the saddle, through which thevertical working spindles slide drill-spin-dle fashion, each spindle being universal-jointed at its top to its balance weightlever. Figs, i and 2. Each balance leveris prolonged in front of the spindle joint,and has pivoted to its front end, next theoperator, a suspended hand rod with ahand loop at the lower end, by which thespindle can be rapidly raised or lowered;the spindle quills are fitted with racks andpinions, the latter being driven from aworm and worm gear driven feed shaft,which gives an independent feed motion toeach of the spindles. The lower end of each spindle has uni-versally jointed to it a downward tele-scoping extension, which can be placed at Fig. 3. WELLS STAYBOLT-SEATING MACHINE.
