Abstract
Abstract A torque support is provided having a casing supported by a pair of symmetrically arranged steering rods which are pivotally mounted to a pair of upwardly slanted guide rods. The guide rods are pivotally supported on a base member. Inter-connecting the guide rods and the steering rods is a tension-compression rod capable of absorbing tensile and compressive forces. All of the elements of the torque support are provided above floor level. The tension-compression rod is constructed as a plurality of elongated sections, separated from one another by gaps. Located within the elongated sections are compressive spring bundles and a shaft bolt which is secured to supporting surfaces of the elongated sections. In this manner, compressive and tensile forces are cpable of being absorbed by the tension-compression rod.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
239 words
A torque support apparatus positioned above floor level comprising: (a) a shaft pivot; (b) a driving sprocket gear non-rotatably mounted on said shaft pivot; (c) a gear box supported on said shaft pivot; (d) at least one drive motor secured to said gear box; (e) each of said drive motors being provided with reduction gearing and a pinion gear; (f) each of said pinion gears meshing with said sprocket gear; (g) parallel steering rods rotatively attached on opposide sides of said gear box by ball and socket-type joints, said steering rods being equally spaced from said gear box and having upper and lower ends; (h) parallel and equal in length guide rods, each having upper and lower ends, the upper ends of said guide rods being attached, by ball and socket-type joints, to the lower ends of steering rods, the lower ends of said guide rods being stationarily arranged, by ball and socket joints; (i) at least one tension-compression rod inter-connecting said parallel guide rods, said rods having at least one internally-positioned spring element and having at least two longitudinal sections separated from one another by a gap; (j) said parallel guide rods, extending in their normal position, slantingly upwardly from said floor level at an angle to said rods; and (k) said tension-compression rods extending between said ball and socket-type joints of said lower ends of said steering rods and between the upper ends of said guide rods.
Claim 2
Dependent Claim
239 words
A torque support apparatus positioned above floor level comprising: (a) a shaft pivot; (b) a driving sprocket gear non-rotatably mounted on said shaft pivot; (c) a gear box supported on said shaft pivot; (d) at least one drive motor secured to said gear box; (e) each of said drive motors being provided with reduction gearing and a pinion gear; (f) each of said pinion gears meshing with said sprocket gear; (g) parallel steering rods rotatively attached on opposide sides of said gear box by ball and socket-type joints, said steering rods being equally spaced from said gear box and having upper and lower ends; (h) parallel and equal in length guide rods, each having upper and lower ends, the upper ends of said guide rods being attached, by ball and socket-type joints, to the lower ends of steering rods, the lower ends of said guide rods being stationarily arranged, by ball and socket joints; (i) at least one tension-compression rod inter-connecting said parallel guide rods, said rods having at least one internally-positioned spring element and having at least two longitudinal sections separated from one another by a gap; (j) said parallel guide rods, extending in their normal position, slantingly upwardly from said floor level at an angle to said rods; and (k) said tension-compression rods extending between said ball and socket-type joints of said lower ends of said steering rods and between the upper ends of said guide rods.
