Motion converter for converting rotation into to-and-fro displacement
First Claim
Patent Images
1. A motion converting apparatus for converting rotational motion to angular reciprocal motion which comprises:
- a tubular housing defining a longitudinal slot therein;
a tool holder pivotally mounted in the housing at a pivot point and including a tool which extends away from the pivot point and out of the housing, and a holder head which extends away from the pivot point and into the housing; and
a transmission element pivotally mounted in the housing by means for pivotally mounting said element and having a first end which receives the holder head of the tool holder, and a second end which is adapted to receive an eccentrically rotating drive head such that the transmission element pivots back and forth due to eccentric rotation of the drive head and transfers such motion to the holder head of the tool holder which in turn imparts reciprocal angular motion to the tool, wherein the transmission element can be positioned at different locations between the drive head and holder head by moving the pivot mounting means along the slot to adjust the amount of reciprocal angular motion of the tool.

Abstract
A motion converter comprising a drive head mounted eccentrically onto a drive shaft, and which is eccentrically displaced when the drive shaft rotates. The converter additionally comprises a displaceable transmission element and a displaceable tool holder holding a tool. The transmission element and tool holder are moved to-and-fro when the drive shaft is rotated. The excursion of the to-and-fro motion is adjustable by pivot means, preferably a first pivot pin, displaceably affixed to a housing and connecting the transmission element to the housing.
