Abstract
Abstract Disclosed herein is a shock-isolating mounting for textile machinery spindles, which comprises a mobile resting block for the spindle with hinging components designed in order to move the spindle from an upright position, in which the spindle is in contact with a control belt, to an inclined position, in which the spindle is in contact with a brake; the above hinging components comprise some hinging units made of elastomeric material and a toggle-jointed thrust element connected in said manner to one of the aforementioned hinging components.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
A shock-isolating mounting for textile machine spindles, said textile machine having a frame, said spindle having a spindle axis, said mounting comprising: a spindle-carrying block defining a main plane thereof perpendicular to said spindle axis, and components for hinging the spindle-carrying block to the frame of the textile machine in order to turn over the spindle from an upright working position, wherein the spindle is in contact with a tangential control belt, to an inclined idle position, wherein the spindle is detached from the belt and is in contact with a braking device; said components for hinging comprising at least a first hinging component, made of elastomeric material, which defines a fixed horizontal axis, as well as at least a second hinging component, made of elastomeric material, which defines a horizontal axis which is mobile and parallel to the fixed horizontal axis; a thrust component having one side hinged to one side of the machine frame and having another side toggle-jointed to said second hinging component; and at least one shock-isolating component, made of elastomeric material, interposed between one part of the spindle-carrying block and a fixed stop surface.
Claim 2
Dependent Claim
189 words
A shock-isolating mounting for textile machine spindles, said textile machine having a frame, said spindle having a spindle axis, said mounting comprising: a spindle-carrying block defining a main plane thereof perpendicular to said spindle axis, and components for hinging the spindle-carrying block to the frame of the textile machine in order to turn over the spindle from an upright working position, wherein the spindle is in contact with a tangential control belt, to an inclined idle position, wherein the spindle is detached from the belt and is in contact with a braking device; said components for hinging comprising at least a first hinging component, made of elastomeric material, which defines a fixed horizontal axis, as well as at least a second hinging component, made of elastomeric material, which defines a horizontal axis which is mobile and parallel to the fixed horizontal axis; a thrust component having one side hinged to one side of the machine frame and having another side toggle-jointed to said second hinging component; and at least one shock-isolating component, made of elastomeric material, interposed between one part of the spindle-carrying block and a fixed stop surface.
Claim 3
Dependent Claim
15 words
A mounting according to claim 1, wherein the thrust component comprises an axial reaction spring.
Claim 4
Dependent Claim
61 words
A mounting according to claim 1, wherein said thrust component includes a first bush which is toggle-jointed to the mobile axis of the spindle-carrying block and a second bush which slides relative to the first bush and which is hinged in a fixed point of the machine frame; further comprising a helical reaction spring interposed between said first and second bushes.
Claim 5
Dependent Claim
28 words
A mounting according to claim 1, wherein said first and second hinging components made of elastomeric material comprise a cylindrical body and define hinges of a rotational type.
Claim 6
Dependent Claim
27 words
A mounting according to claim 1, wherein said first and second hinging components are made of an elastomeric material section, which defines a flexing type of hinge.
Claim 7
Dependent Claim
42 words
A mounting according to claim 1, comprising a bracket supporting said first hinging component, and wherein the spindle-carrying block, the bracket supporting the first hinging component, and the thrust component, respectively, provide oppositely diverging surfaces on both sides of the hinging axis.
Claim 8
Dependent Claim
42 words
A mounting according to claim 1, wherein the tangential control belt defines a plane thereof, and wherein the first hinging axis is positioned beneath the tangential control belt and on a plane which lies behind the plane of the tangential control belt.
