Abstract
Abstract A traveling service unit for an associated textile spinning mill machine may be elevationally adjusted with respect to a reference rail mounted longitudinally along the machine by a feeler guide element pivotably mounted to the service unit in following engagement to the reference guide rail in conjunction with an operatively associated controller connected with vertically adjustable roller support assemblies of the service unit 1 for varying the elevation of the service unit 1 as necessary to compensate for deviations in the pivotal disposition of the feeler guide element with respect to horizontal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
In combination, a textile spinning mill machine, a service unit for traveling movement along said spinning mill machine for performing servicing operations thereon, and apparatus for vertical adjustment of said traveling service unit with respect to said spinning mill machine, said adjustment apparatus comprising a guide rail arranged as an elevation reference longitudinally along the textile spinning mill machine in a predetermined relationship thereto, a feeler guide element arranged for engagement with said reference guide rail for guiding the traveling service unit therealong, and means associated with said feeler guide element for controlling elevational adjustment of said traveling service unit in relation to said reference guide rail.
Claim 2
Dependent Claim
107 words
In combination, a textile spinning mill machine, a service unit for traveling movement along said spinning mill machine for performing servicing operations thereon, and apparatus for vertical adjustment of said traveling service unit with respect to said spinning mill machine, said adjustment apparatus comprising a guide rail arranged as an elevation reference longitudinally along the textile spinning mill machine in a predetermined relationship thereto, a feeler guide element arranged for engagement with said reference guide rail for guiding the traveling service unit therealong, and means associated with said feeler guide element for controlling elevational adjustment of said traveling service unit in relation to said reference guide rail.
Claim 3
Dependent Claim
70 words
The combination according to claim 1 and characterized further in that said feeler guide element comprises a lever arm pivotably mounted at one end to said traveling service unit about a horizontal pivot axis and being guided at the opposite end of said lever arm along said reference guide rail for vertical adjustment of said traveling service unit in relation to the angular relationship of said level arm to horizontal.
Claim 4
Dependent Claim
47 words
The combination according to claim 2 and characterized further in that said controlling means comprises an inclination detector operatively connected to said lever arm for detecting the angular relationship thereof to horizontal and for producing a corresponding control signal for vertical adjustment of the traveling service unit.
Claim 5
Dependent Claim
19 words
The combination according to claim 3 and characterized further in that said inclination detector comprises an electronic level detector.
Claim 6
Dependent Claim
41 words
The combination according to claim 1 and characterized further by a means for supporting the traveling service unit on a floor surface and being selectively adjustable for adjusting the elevation of the traveling service unit with respect to the floor surface.
Claim 7
Dependent Claim
42 words
The combination according to claim 5 and characterized further in that said supporting means includes a plurality of roller assemblies mounted to the traveling service unit for rolling floor engagement, each roller assembly being adjustable vertically relative to the traveling service unit.
Claim 8
Dependent Claim
51 words
The combination according to claim 5 and characterized further in that said supporting means comprises a plurality of support assemblies for the traveling service unit, each support assembly being adjustable vertically relative to the traveling service unit, one support assembly being mounted to an undercarriage associated with the traveling service unit.
Claim 9
Dependent Claim
31 words
The combination according to claim 1 and characterized further in that said feeler guide element is disposed in an operating area of the traveling service unit having operational service components thereof.
Claim 10
Dependent Claim
41 words
The combination according to claim 1 and characterized further by a control element operatively associated with said feeler guide element for detecting the elevation of the traveling service unit and for deactuating it when a predetermined elevation tolerance range is exceeded.
