Abstract
Abstract A support for containing a nut operating on a rotating threaded shaft where the nut is connected to a part mounted for linear movement essentially along the axis of the shaft and in which the support between the nut and the part accommodates misalignment between the shaft and the part without introducing dimensional error along the axis of the shaft.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A support for a nut relatively movable in a linear direction and which cooperates with a threaded shaft with the support accommodating misalignment between the direction and the shaft comprising a housing adapted to be mounted on a part mounted for relative linear movement with respect to the shaft and movable with the part, a threaded shaft having an axis extending essentially parallel with the direction of movement, an elongate threaded nut positioned within the housing and adapted to threadingly cooperate with the threaded shaft, first nut containing means for containing the nut within the housing and for enabling relative movement of the nut in the housing essentially perpendicular to the axis of the shaft and second nut containing means for containing the nut within the housing and for enabling relative angular movement of the nut with respect to the housing.
Claim 2
Dependent Claim
141 words
A support for a nut relatively movable in a linear direction and which cooperates with a threaded shaft with the support accommodating misalignment between the direction and the shaft comprising a housing adapted to be mounted on a part mounted for relative linear movement with respect to the shaft and movable with the part, a threaded shaft having an axis extending essentially parallel with the direction of movement, an elongate threaded nut positioned within the housing and adapted to threadingly cooperate with the threaded shaft, first nut containing means for containing the nut within the housing and for enabling relative movement of the nut in the housing essentially perpendicular to the axis of the shaft and second nut containing means for containing the nut within the housing and for enabling relative angular movement of the nut with respect to the housing.
Claim 3
Dependent Claim
47 words
The invention as defined in claim 1 in which the housing has ends having appertures through which the shaft passes, the nut is positioned between the ends and each nut containing means has two portions with a portion of each located between the nut and each end.
Claim 4
Dependent Claim
51 words
The invention as defined in claim 2 in which one end of the housing is mounted for movement with respect to the other end along the axis of the nut and in which the one end axially retains the nut and both nut containing means against the ends of the housing.
Claim 5
Dependent Claim
48 words
The invention as defined in claim 1 in which the first nut containing means includes at least at one end of the nut a pair of parallel surfaces perpendicular to the axis of the nut and movable bearing means mounted between The surfaces to enable relative movement therebetween.
Claim 6
Dependent Claim
48 words
The invention as defined in claim 4 in which the nut has a flange having an outer surface forming one of the parallel surfaces, the other surface is formed by the second nut containing means and in which the movable bearing means includes a plurality of caged balls.
Claim 7
Dependent Claim
38 words
The invention as defined in claim 1 in which the second nut containing means includes a portion having two parts, said parts being arranged to be pivotable with respect to each other to form a spherical bearing means.
Claim 8
Dependent Claim
35 words
The invention as defined in claim 6 in which one part is maintained stationary with respect to the housing and in which the other part pivots to become aligned with the axis of the shaft.
Claim 9
Dependent Claim
62 words
The invention as defined in claim 7 in which the other part has a flat surface that is perpendicular to the axis of the nut, in which the nut has an adjacent flat surface parallel to the flat surface and in which bearing means are positioned between the two surfaces with the bearing means and surfaces constituting the first nut containing means.
