Abstract
Abstract A resilient element connects the housing of the spindle collar bearing with the spindle rail and contains a circumferential arrangement of resiliently flexible rods surrounding with play the housing of the spindle collar bearing in a substantially parallel relationship thereto. The resiliently flexible rods which are arranged at substantially uniform circumferential spacing from one another extend at both of their ends from an associated common retaining sleeve for the related rod ends. One such retaining sleeve is anchored at the spindle rail. The other retaining sleeve is fixedly anchored at the housing of the spindle collar bearing in a region or at a location spaced from a housing side at which the spindle exits from such housing. The resilient element forms a spatial parallelogram permitting only radial movement of the housing against the spring action of the resiliently flexible rods without inclined positioning of the housing.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
227 words
A device for radially movably mounting at a spindle rail of a textile machine, particularly a spinning or twisting machine, a housing of a spindle collar bearing of a spindle, particularly a spinning or twisting spindle which exits at a predetermined housing side from such housing, said device comprising: a resilient element structured for mounting at said spindle rail and at said housing of the spindle collar bearing; said resilient element having two ends; said resilient element containing a retaining sleeve at each one of its two ends; said resilient element further containing a plurality of resiliently flexible rods which extend between said retaining sleeves; said resiliently flexible rods being substantially circumferentially arranged at said resilient element such as to extend substantially parallel to and at a predetermined clearance from at least part of said housing of the spindle collar bearing; said resiliently flexible rods being substantially circumferentially arranged at said resilient element at substantially equal circumferential spacing from one another; a first one of two retaining sleeves being structured to be anchored at said spindle rail; and a second one of the two retaining sleeves being structured to be fixedly anchored at the housing of the spindle collar bearing in a region which is spaced from said predetermined housing side at which said spinning or twisting spindle exits from said housing of the spindle collar bearing.
Claim 2
Independent Claim
227 words
A device for radially movably mounting at a spindle rail of a textile machine, particularly a spinning or twisting machine, a housing of a spindle collar bearing of a spindle, particularly a spinning or twisting spindle which exits at a predetermined housing side from such housing, said device comprising: a resilient element structured for mounting at said spindle rail and at said housing of the spindle collar bearing; said resilient element having two ends; said resilient element containing a retaining sleeve at each one of its two ends; said resilient element further containing a plurality of resiliently flexible rods which extend between said retaining sleeves; said resiliently flexible rods being substantially circumferentially arranged at said resilient element such as to extend substantially parallel to and at a predetermined clearance from at least part of said housing of the spindle collar bearing; said resiliently flexible rods being substantially circumferentially arranged at said resilient element at substantially equal circumferential spacing from one another; a first one of two retaining sleeves being structured to be anchored at said spindle rail; and a second one of the two retaining sleeves being structured to be fixedly anchored at the housing of the spindle collar bearing in a region which is spaced from said predetermined housing side at which said spinning or twisting spindle exits from said housing of the spindle collar bearing.

Claim 4
Dependent Claim
44 words
The device as defined in claim 1, wherein: said resiliently flexible rods are made of metal; and each of said resiliently flexible rods has a substantially rectangular cross-section with narrow sides directed substantially radially with respect to said housing of the spindle collar bearing.
Claim 5
Dependent Claim
17 words
The device as defined in claim 1, wherein: said resiliently flexible rods possess a substantially round cross-section.
Claim 6
Dependent Claim
8 words
The device as defined in claim 1, wherein:
Claim 7
Dependent Claim
11 words
said retaining sleeves are formed integrally with said resiliently flexible rods.
Claim 8
Dependent Claim
11 words

Claim 9
Dependent Claim
31 words
The device as defined in claim 5, wherein: said integrally formed retaining sleeves and resiliently flexible rods contain substantially oblong, oval intermediate spaces between individual ones of the resiliently flexible rods.
Claim 10
Dependent Claim
51 words
The device as defined in claim 1, wherein: said first retaining sleeve is provided with a flange for anchoring to said spindle rail; said spindle rail contains an open-ended bore; and said resiliently flexible rods extending from said first retaining sleeve with play through said open-ended bore in said spindle rail.
Claim 11
Dependent Claim
47 words
The device as defined in claim 1, wherein: said housing of the spindle collar bearing contains a lower end; and said second retaining sleeve extending around said lower end of said housing of the spindle collar bearing and at least partially engaging said lower end from below.
Claim 12
Dependent Claim
30 words
The device as defined in claim 8, wherein: said lower end of said housing of the spindle collar bearing and said second retaining sleeve are interconnected by a press fit.
Claim 13
Dependent Claim
38 words
The device as defined in claim 1, wherein: each said resiliently flexible rod defines two ends; and each said resiliently flexible rod is constructed with a cross-section which increases towards said two ends of said resiliently flexible rods.
Claim 14
Dependent Claim
25 words
The device as defined in claim 10, wherein: said resilient element contains substantially oblong, oval intermediate spaces between individual ones of the resiliently flexible rods.
Claim 15
Dependent Claim
20 words
