Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
An apparatus for tensioning a belt of a belt-driven device comprising, an integral mount including a base plate forming two upright ends defining two axially aligned pivot holes on a pivotal axis, a belt-driven device having a rigid housing, a pivotal support on each end of said housing forming extensions of said housing, means defining axially aligned openings in said supports, connecting means connecting said supports to said housing, fastening means pivotally fastening said supports on said upright ends of said integral mount aligning said openings and holes on said pivotal axis, means defining an adjusting slot in a first of said supports, a fastener received in said slot for adjustably positioning one of said supports on one of said uprights, a supporting link for adjustably supporting the other of said supports, said link defining a slot, a second fastener for adjustably supporting said other one of the said supports on said supporting link to thereby adjustably mount said belt-driven device in an infinite number of positions for tensioning of the drive belt.
Claim 2
Independent Claim
173 words
An apparatus for tensioning a belt of a belt-driven device comprising, an integral mount including a base plate forming two upright ends defining two axially aligned pivot holes on a pivotal axis, a belt-driven device having a rigid housing, a pivotal support on each end of said housing forming extensions of said housing, means defining axially aligned openings in said supports, connecting means connecting said supports to said housing, fastening means pivotally fastening said supports on said upright ends of said integral mount aligning said openings and holes on said pivotal axis, means defining an adjusting slot in a first of said supports, a fastener received in said slot for adjustably positioning one of said supports on one of said uprights, a supporting link for adjustably supporting the other of said supports, said link defining a slot, a second fastener for adjustably supporting said other one of the said supports on said supporting link to thereby adjustably mount said belt-driven device in an infinite number of positions for tensioning of the drive belt.
Claim 3
Dependent Claim
59 words
An apparatus for tensioning a belt of the belt-driven device as set forth in claim 1 including, a pulley shield, a means for fastening a portion of said shield to one of said supports on said housing, and means fastening a second portion of said shield to said housing and said link for providing a housing mounted belt shield.
Claim 4
Dependent Claim
34 words
An apparatus for tensioning a belt of a belt-driven device as set forth in claim 1 wherein said connecting means connects said shield and one of said supports to said housing and said link.
Claim 5
Dependent Claim
29 words
