Abstract
Abstract An adjustable suspension support having a suspensible vertical cylinder, a coaxial shaft in the cylinder, a brake device on the upper end of the shaft, a grip device carried by the lower end of the shaft with an associated lever, a spacer tube between the brake and the grip, and at least one hanger on the support for holding an object. The brake means has a collar carrying spherical bearings and a plug on the end of the shaft retaining the bearings in the cage. The device is rotatable about its vertical axis and it is adjustable vertically by actuating the lever and exerting an upward force on the grip to release the brake.

Claim 1
Independent Claim
208 words
An adjustable suspension support comprising: a vertical cylinder and means at the upper end of the cylinder for suspension thereof; a shaft coaxially located in the cylinder; brake means slidable in the cylinder and comprising a cylindrical collar coaxial with the shaft, the collar having a plurality of radial apertures located in a circumferential plane thereof, the upper end of the shaft carrying a plug located within the collar adjacent the apertures, the plug having an inverted frustro-conical side wall, a plurality of spherical bearings one located in each aperture of the collar and retained therein by the plug to bear laterally against the cylinder; grip means carried by the lower end of the shaft and including lever means operable to move the grip means axially downward with respect to the shaft; a spacer tube concentric with the shaft and freely slidable thereon, the lower end of the tube abutting the grip means and the upper end abutting the collar when the lever means is not operated; and means connected with the support to carry an object; whereby on operating the lever means and exerting an upward force on the grip means the plug is raised with respect to the collar and the brake means is thereby released.

An adjustable suspension support comprising: a vertical cylinder and means at the upper end of the cylinder for suspension thereof; a shaft coaxially located in the cylinder; brake means slidable in the cylinder and comprising a cylindrical collar coaxial with the shaft, the collar having a plurality of radial apertures located in a circumferential plane thereof, the upper end of the shaft carrying a plug located within the collar adjacent the apertures, the plug having an inverted frustro-conical side wall, a plurality of spherical bearings one located in each aperture of the collar and retained therein by the plug to bear laterally against the cylinder; grip means carried by the lower end of the shaft and including lever means operable to move the grip means axially downward with respect to the shaft; a spacer tube concentric with the shaft and freely slidable thereon, the lower end of the tube abutting the grip means and the upper end abutting the collar when the lever means is not operated; and means connected with the support to carry an object; whereby on operating the lever means and exerting an upward force on the grip means the plug is raised with respect to the collar and the brake means is thereby released.
Claim 3
Dependent Claim
32 words
A support as claimed in claim 1 including an outer sleeve concentric with the cylinder and freely slidable thereon, the sleeve being fixed at the lower end thereof to the grip means.
Claim 4
Dependent Claim
18 words
A support as claimed in claim 2 including means projecting outwardly from the sleeve to support an object.
Claim 5
Dependent Claim
22 words
A support as claimed in claim 3 in which the outwardly projecting means is slidable along the sleeve and releasably clamped thereon.
Claim 6
Dependent Claim
44 words
A support as claimed in claim 3 in which the outwardly projecting means comprises a hanger having a collar slidable on the outer sleeve, and at least one arm projecting outwardly from the collar; said clamping means clamping the collar releasably on the sleeve.
Claim 7
Dependent Claim
62 words
A support as claimed in claim 1 in which the grip means comprises a hollow handle defining an inner chamber, the lower end of the shaft projecting into the chamber, the lever means comprising a lever pivoted on the handle intermediate its ends, one end of the lever projecting into the chamber and bearing laterally against the lower end of the shaft.
Claim 8
Dependent Claim
24 words
A support as claimed in claim 6 in which the lower end of the shaft is urged against the lever by a compression spring.
Claim 9
Dependent Claim

A support as claimed in claim 1 in which the lower end of the cylinder terminates in an inturned lip whereby the brake means is stopped from passing out therefrom.
Claim 10
Dependent Claim
64 words
A support as claimed in claim 1 in which the collar of the brake means includes an inturned flange at the lower end thereof, the upper end of the spacer tube bearing against the flange, and a compression spring within the collar coaxial with the shaft, one end of the spring abutting the flange and the other end of the spring abutting the plug.
Claim 11
Dependent Claim
20 words
A support as claimed in claim 1 in which the plug is threaded onto the upper end of the shaft.
