Abstract
Abstract A braking mechanism for an independent power take-off unit that prevents the independent power take-off shaft from rotating through an arc of more than 360* when the clutch is disengaged, but permits free rotation of the independent power take-off shaft through an arc of less than 360*.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
68 words
In an I.P.T.O. assembly the combination comprising: an input shaft; an output shaft; clutch means for engaging and disengaging said input and output shafts; and frictionally connected brake means including an annular ring having at least one radial projection thereon for simultaneously restricting said output shaft from rotating through a 360* arc in either direction and permitting said output shaft to rotate through an arc greater than 0*.
Claim 2
Dependent Claim
68 words
In an I.P.T.O. assembly the combination comprising: an input shaft; an output shaft; clutch means for engaging and disengaging said input and output shafts; and frictionally connected brake means including an annular ring having at least one radial projection thereon for simultaneously restricting said output shaft from rotating through a 360* arc in either direction and permitting said output shaft to rotate through an arc greater than 0*.
Claim 3
Dependent Claim
72 words
In an I.P.T.O. assembly the combination comprising: a power input shaft; a splined output shaft; clutch means for engaging and disengaging said input and output shafts; and brake means including an annular ring having at least one radial projection thereon and being carried by said output shaft and frictionally connected thereto when said clutch is disengaged whereby restricting said output shaft from rotating through an arc greater than 360* in either direction.
Claim 4
Dependent Claim
72 words
In an I.P.T.O. assembly the combination comprising: a power input shaft; a splined output shaft; clutch means for engaging and disengaging said input and output shafts; and brake means including an annular ring having at least one radial projection thereon and being carried by said output shaft and frictionally connected thereto when said clutch is disengaged whereby restricting said output shaft from rotating through an arc greater than 360* in either direction.
Claim 5
Dependent Claim
86 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; a clutch means for engaging and disengaging said input and output shafts; an annular ring, comprising at least one radial projection, rotatably mounted on said output shaft; a lug projecting from said housing and disposed in interfering relationship with said projection; and means for holding said annular ring in fixed relationship to said output shaft when said clutch is disengaged.
Claim 6
Dependent Claim
86 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; a clutch means for engaging and disengaging said input and output shafts; an annular ring, comprising at least one radial projection, rotatably mounted on said output shaft; a lug projecting from said housing and disposed in interfering relationship with said projection; and means for holding said annular ring in fixed relationship to said output shaft when said clutch is disengaged.
Claim 7
Dependent Claim
102 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; a clutch means for engaging and disengaging said input and output shafts; said clutch means comprising an annular backing plate and carrying a relative rotatable member having a radial projection thereon, means for reciprocating said backing plate to frictionally engage and disengage said rotatable member; a lug projecting from said housing disposed relative to said projection in an interfering relationship with reciprocation of said backing plate causing said rotatable member to rotate with said clutch means.
Claim 8
Dependent Claim
102 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; a clutch means for engaging and disengaging said input and output shafts; said clutch means comprising an annular backing plate and carrying a relative rotatable member having a radial projection thereon, means for reciprocating said backing plate to frictionally engage and disengage said rotatable member; a lug projecting from said housing disposed relative to said projection in an interfering relationship with reciprocation of said backing plate causing said rotatable member to rotate with said clutch means.
Claim 9
Dependent Claim
83 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; clutch means for engaging and disengaging said input and output shafts; a radial projection carried by said clutch; means on said clutch for frictionally constraining said radial projection for rotation with said clutch; lug means disposed on said housing; and means for placing said lug and said projection in interfering relationship upon disengagement of said clutch means.
Claim 10
Dependent Claim
83 words
An I.P.T.O. assembly comprising: an input shaft, journaled within a stationary housing, for receiving power from a vehicle; a splined output shaft journaled within said housing; clutch means for engaging and disengaging said input and output shafts; a radial projection carried by said clutch; means on said clutch for frictionally constraining said radial projection for rotation with said clutch; lug means disposed on said housing; and means for placing said lug and said projection in interfering relationship upon disengagement of said clutch means.
