Abstract
Apparatus for converting oscillatory motion to reciprocating motion featuring the use of thin, non-permanently deformable band-like members confined to a linear track so as to be reciprocable when one end of the band-like member is engaged by an oscillatory shaft. The other end of the band-like member may be secured to a work element used for exerting force against a work object. Selection means may be employed in apparatus having a plurality of band-like members in which each of the members can be selectively induced into engagement with a shaft or other oscillatory means to control the work elements as desired.
Claims17
A means of converting oscillating motion to reciprocating motion, comprising:
- an oscillatory member;
- structure adjacent to said oscillatory member forming a peripheral track around at least a portion of said oscillatory member;
- structure forming a track extending from said oscillatory member;
- a band-like member selectively engageable with said oscillatory member and extendable within said extending track from said oscillatory member, said extending track preventing unwanted flexing of said band-like member within said extending track, a work end of said band-like member being away from said oscillatory member and reciprocable when said band-like member is engaged by said oscillatory member;
- and,
- means for causing said band-like member to become engaged with said oscillatory member.
Driving apparatus including a selection device wherein one of a plurality of band selection members are selected comprising an oscillatory member;
- walls adjacent to said oscillatory member forming a peripheral track around at least a portion of said oscillatory member;
- structure forming a confining track extending from said oscillatory member;
- and means of selecting one of said plurality of selection band members, each of said plurality of band selection members being engageable with said oscillatory member upon selection and extendable within said confining track from said oscillatory member, each of said band selection members having an end removed from said oscillatory member which is reciprocable when said band selection member is engaged by said oscillatory member.
Driving apparatus comprising:
- an oscillatory member having circumferential grooves;
- structure adjacent said oscillatory member wherein a first groove forms a track around at least a portion of said oscillatory member;
- a band member slidable within said first groove and having protruding structure positioned within a second groove, said band member further having an element extendable from said protruding structure and engageable within a third groove;
- a pin extendable through said protruding structure to be engageable with said element, said band member having an actuating portion engageable with said pin;
- and
- actuation means positioned to drive said actuating portion against said pin thereby causing said element to be engaged in said third groove.
Driving apparatus for converting oscillating motion to reciprocating motion comprising:
- an oscillatory member;
- a track around a portion of said oscillatory member and extending away from said oscillatory member;
- a band-like member selectively engageable by a portion of said oscillatory member and extendable within said track, said band-like member having an end removed from said oscillatory member and reciprocable as said band-like member is engaged by said oscillatory member;
- and
- means to cause said band-like member to become engaged with said oscillatory member.
