Description: |
| Abstract:
This invention relates to certain improvements in foot-power mechanisms by which power may be conveniently and effectively imparted to sewing machines, drills, lathes and other light machinery by the foot on the user when the user is either sitting or standing, the movement being not in the nature of that compelled by an oscillating treadle, but being a forward directed "kick", by which means the foot-muscles are less fatigued than when motion is given by the ankle; and for this purpose the invention consists of a foot-power mechanism which comprises upright standards, a fly-wheel the shaft of which is supported in bearings of said standards, a clutch on the shaft of the fly-wheel, a pinion on said clutch, a toothed segment meshing with said pinion, and a lever attached to the segment and provided with a foot-rest at its lower end, the upper end of the segment being provided with a lateral stop for limiting the forward or return movement of the segment and foot-lever by contact with the casing of the clutch. The invention consists, further, of a pivoted and spring-actuated knee-brake which is applied to the upper end of the standards for permitting the quick stoppage of the foot-power by the attendant whenever required.
Claims:
1. A foot-power mechanism, consisting of upright standards, a fly-wheel, the shaft of which is supported in bearings of said standards, a clutch applied to the shaft of said flywheel, a pinion on said clutch, a foot-lever fulcrumed to one of said standards and provided with a foot-rest at its lower end, a toothed segment attached to the upper end of said foot-lever and adapted to mesh with the pinion on the clutch, and a laterally-extending stop-pin at the upper end of said segment, substantially as set forth.
2. In a foot-power mechanism, the combination, with upright standards, of a fly-wheel, the shaft of which is supported in bearings of said standards, a clutch applied to the shaft of said fly-wheel, a pinion on said clutch, a foot-lever fulcrumed to one said standards, a toothed segment pivoted to mesh with said pinion, means connecting said segment at its lower end with the foot-lever, and a stop-pin connecting said foot-lever and segment at the upper end of the later and projecting laterally therefrom into line with the clutch, substantially as set forth. |
