Abstract
Abstract Disclosed is a spindle mounting means carried in part by the spindle rail in the form of a convex spherical seat surface at the spindle receiving orifice and more than two joining holes thereabout which are threaded, and in part by the spindle assembly in the form of an encircling mounting member rigidly fixed thereto having a complementary convex seat surface for abutment with the rail seat and a laterally extending flange extending outwardly from the seat, the flange having a similar number and spacing of joining holes which are not threaded but are of larger diameter than the joining holes of the rail, and a similar number of joining and fixing members in the form of bolts which are passed through the wider flange holes and threaded and tightened into the rail holes, whereby spindle plumbing using this construction is achievable within five to fifteen seconds versus five to fifteen minutes with prior art constructions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
264 words
In a textile yarn processing machine having a substantially horizontal spindle rail fixed longitudinally thereto; a vertically reciprocable, substantially horizontal ring rail interconnected with said machine for said vertical reciprocatory traverse relative thereto and extending substantially parallel and above said spindle rail; a spindle assembly joined to said spindle rail having a vertically disposed spindle blade with a similarly oriented axis of rotation; and a ring and ring traveler assembly joined to said ring rail for traverse therewith disposed in a substantially horizontal orientation encircling said spindle blade in the range of said traverse; the improvement comprising: spindle assembly mounting means for directly mounting said spindle assembly upon said spindle rail such that said blade is oriented axially central to said ring assembly throughout said range of vertical traverse; said mounting means comprising: a mounting member fixed to said spindle assembly, bearing a spherical convex surface encircling said assembly and extending outwardly thereof, and a mounting flange extending laterally outward from said surface; a spherical concave surface carried by said spindle rail, of complementary arcuity to said convex surface of said mounting member for adjustable abutment therewith and defining a receiving orifice through said spindle rail for said spindle assembly; and joining means a. for directly joining said mounting member flange to said spindle rail, b. for adjustably tilting said spindle blade and assembly to an orientation wherein said ring assembly throughout the range of said traverse is axially concentric to said rotational axis of said spindle blade, and c. for directly fixing said spindle assembly rigidly to said spindle rail at said orientation.
Claim 2
Dependent Claim

In a textile yarn processing machine having a substantially horizontal spindle rail fixed longitudinally thereto; a vertically reciprocable, substantially horizontal ring rail interconnected with said machine for said vertical reciprocatory traverse relative thereto and extending substantially parallel and above said spindle rail; a spindle assembly joined to said spindle rail having a vertically disposed spindle blade with a similarly oriented axis of rotation; and a ring and ring traveler assembly joined to said ring rail for traverse therewith disposed in a substantially horizontal orientation encircling said spindle blade in the range of said traverse; the improvement comprising: spindle assembly mounting means for directly mounting said spindle assembly upon said spindle rail such that said blade is oriented axially central to said ring assembly throughout said range of vertical traverse; said mounting means comprising: a mounting member fixed to said spindle assembly, bearing a spherical convex surface encircling said assembly and extending outwardly thereof, and a mounting flange extending laterally outward from said surface; a spherical concave surface carried by said spindle rail, of complementary arcuity to said convex surface of said mounting member for adjustable abutment therewith and defining a receiving orifice through said spindle rail for said spindle assembly; and joining means a. for directly joining said mounting member flange to said spindle rail, b. for adjustably tilting said spindle blade and assembly to an orientation wherein said ring assembly throughout the range of said traverse is axially concentric to said rotational axis of said spindle blade, and c. for directly fixing said spindle assembly rigidly to said spindle rail at said orientation.
Claim 3
Dependent Claim
27 words
The improvement as in claim 1, wherein said convex spherical surface of said mounting member has its spherical center on said axis of rotation of said blade.
Claim 4
Dependent Claim
30 words
The improvement as in claim 2, wherein said spherical center of said convex surface is on said axis of rotation in the range of the lower half of said blade.
Claim 5
Dependent Claim
36 words
The improvement as in claim 3, wherein said spherical center on said axis of rotation is at an elevation corresponding to the elevation of the lowest wrap of yarn to be wound by said spindle assembly.
Claim 6
Dependent Claim
28 words
The improvement as in claim 1, wherein said concave spherical surface carried by said spindle rail has its spherical center on said axis of rotation of said blade.
Claim 7
Dependent Claim
24 words
The improvement as in claim 1, wherein said joining means is carried in part by said flange and in part by said spindle rail.
Claim 8
Dependent Claim
132 words
The improvement as in claim 6, wherein said joining means includes a portion of said spindle rail circumferential said concave spherical surface carried thereby, formed with a plurality in excess of two holes therethrough, said holes forming a set thereof and being spaced from one another about said concave surface, a portion of said flange of said mounting member circumferential said convex spherical surface thereof, formed with a similar plurality of other holes therethrough forming another set of holes and being similarly spaced from one another about said convex surface as are said holes through said spindle rail, and a simiLar plurality of adjustable joining and fixing members engageable with corresponding parts of said portions of said spindle rail and said mounting member flange through the corresponding holes of said sets thereof.
Claim 9
Dependent Claim
38 words
The improvement as in claim 7, wherein the walls defining the holes of one of said sets have a greater diameter cross section than that of the second set, and the walls of said second set are threaded.
Claim 10
Dependent Claim
75 words
The improvement as in claim 8, wherein said adjustable joining and fixing members are threaded bolts, the bolt heads of which are engageable with one of said portions of said spindle rail and flange and the threaded portions of which are engageable with the threaded walls of said second set of holes, wherein said portion so engageable and said threaded walls are in different ones of said portions of said spindle rail and said flange.
Claim 11
Dependent Claim
38 words
The improvement as in claim 9, wherein said threaded walls are in said spindle rail portion and said concave and convex surfaces in abutment with one another are above the lower horizontal surface of said spindle rail portion.
Claim 12
Dependent Claim
16 words
The improvement as in claim 1, wherein said convex surface is integral with said spindle rail.
