Claim 4

A spring support comprising a body, compression spring means located in said body, carrier means connected to said spring means and constructed and arranged to be engaged with a load, such as a pipe, to connect the load to said spring means to be supported thereby, and locking means which acts between said spring means and said body for locking said spring means in an infinite number of longitudinal positions within an operating range of longitudinal movement of said spring means, said spring means having an associated component which is longitudinally movable with said spring means and has parts projecting laterally of said spring means which are diametrically opposed with respect to the longitudinal axis of operating movement of said spring means, and said locking means comprising two elongated externally threaded members each of which has nuts engaged therewith, said threaded members being fixed to said body and extending alongside said spring means in the direction of longitudinal movement thereof at corresponding diametrically opposed positions to said projecting parts of said component, said projecting parts freely co-operating with said threaded members, and said nuts being movable on said threaded member at opposite sides of said projecting parts between released positions in which they are spaced from said projecting parts and leave said component, and thereby said spring means, free to move longitudinally relative to said threaded member, and locking positions in which said nuts are tightened against said projecting parts to prevent said component from moving relative to said threaded members and thereby lock said spring means against longitudinal movement.

Claim 5

A spring support according to claim 2 wherein said body has elongated gaps in its walls which extend in the direction of the longitudinal axis of operating movement of said spring means and through which said projecting parts extend laterally out of said body, and said threaded members are fixed to said body externally thereof opposite said gaps.

Claim 6

A spring support according to claim 3 wherein said body comprises two similar and opposed side wall members which are laterally spaced apart to define said gaps between them, and two end plates between and to which said side wall members are fixed, said end plates having portions projecting outwardly beyond said side wall members to which said threaded members are fixed.

Claim 7

A spring support according to claim 4 wherein said body is of rhomboidal form, said side wall members being of V-section and said end plates being of generally rhomboidal shape.

Claim 8

A spring support according to claim 3 wherein a scale of lineal measurements is provided on said body adjacent to and extending longitudinally of one of said gaps, and said projecting part at said one gap carries an indicator which registers with said scale to indicate the extent of deflection of said spring means under applied loads.

Claim 9

A spring support according to claim 2 wherein said carrier means comprises said component which is supported by said spring means at one end thereof, and connecting means attached to said component for connecting said component to a load to be supported by said spring means.

Claim 10

A spring support according to claim 7 wherein said connecting means comprises an elongate member which extends co-axially through said spring means and out of said body adjacent the opposite end of said spring means from said end at which said component is supported.

Claim 11

A spring support according to claim 8 wherein said member is attached to said component by a pivoted connection, and said body has an aperture through which said member projects out of said body and which permits said member to swing about said pivotal connection.

Claim 12

A spring support according to claim 7 wherein said connecting means comprises an elongate member which extends co-axially away from said spring means and out of said body adjacent to said one end of said spring means at which said component is supported.

Claim 13

A spring support according to claim 10 wherein a load plate is rotatably mounted on an end of said member remote from said component, said load plate being rotatable about the longitudinal axis of said member and providing a seat for a load to be supported.

Claim 14

A spring support according to claim 10 wherein a load plate is fixed at an end of said member remote from said component, and a floating platform is rotatably mounted on said load plate, said floating platform being rotatable about an axis extending in the direction of the longitudinal axis of said spring means and providing a seat for a load to be supported.

Claim 15

A spring support according to claim 10 wherein a guide is fixed to said body within said spring means and said member has a portion complementary to said guide slidingly engaged with said guide.

Claim 16

An assembly for a spring support, comprising compression spring means, first and second members engaged with opposite ends of said spring means, said first member being constructed and arranged for fixture as a part of a body of a spring support, said second member being constructed and arranged for connection thereto of carrier means for connecting a load, such as a pipe, to said second member, and said first and second members each having parts projecting laterally of said spring means which are diametrically opposed with respect to the longitudinal axis of operating movement of said spring means and said projecting parts of said second member having openings therein, and locking means comprising two elongated externally threaded members and pairs of nuts threadedly engaged with said threaded members, said threaded members being fixed to said projecting parts of said first member, extending alongside said spring means in the direction of longitudinal movement thereof and passing freely through said openings in said projecting parts of said second member, and said nuts being engaged with said threaded members at opposite sides of said projecting parts of said second member and being movable on said threaded members between released positions in which said nuts are spaced from said projecting parts and leave said second member, and thereby said spring means, free to move longitudinally relative to said threaded members, and locking positions in which said nuts are tightened against said projecting parts and prevent said second member from moving relative to said threaded members, thereby locking said spring means against longitudinal movement.

Claim 17

An assembly for a spring support, comprising compression spring means, first and second members engaged with opposite ends of said spring means, said first member being constructed and arranged for fixture as a part of a body of a spring support, said second member being constructed and arranged for connection thereto of carrier means for connecting a load, such as a pipe, to said second member, and said first and second members each having parts projecting laterally of said spring means which are diametrically opposed with respect to the longitudinal axis of operating movement of said spring means and said projecting parts of said second member having openings therein, and locking means comprising two elongated externally threaded members and pairs of nuts threadedly engaged with said threaded members, said threaded members being fixed to said projecting parts of said first member, extending alongside said spring means in the direction of longitudinal movement thereof and passing freely through said openings in said projecting parts of said second member, and said nuts being engaged with said threaded members at opposite sides of said projecting parts of said second member and being movable on said threaded members between released positions in which said nuts are spaced from said projecting parts and leave said second member, and thereby said spring means, free to move longitudinally relative to said threaded members, and locking positions in which said nuts are tightened against said projecting parts and prevent said second member from moving relative to said threaded members, thereby locking said spring means against longitudinal movement.
