Abstract
Abstract The specification discloses a vibratory apparatus comprising a fixed base, a vibratory frame arranged for vibration with respect to the fixed base and mounting means for mounting the vibratory frame on the fixed base, the mounting means comprising at least one elongate member upstanding from the fixed base, the member being attached by means of a block of resilient material at its lower end to the fixed base, and being attached by means of a further block of resilient material at its upper end to the vibratory frame, the blocks of resilient material being arranged to allow the vibratory frame to vibrate horizontally, vertically or a combination thereof.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
218 words
A vibratory apparatus comprising a base, a vibratory frame superimposed on the base, and means for mounting the frame on the base for vibration with respect thereto, which means is provided by a plurality of mounting devices each located between the frame and the base, and comprising a pair of opposed elastomeric bushes which are spaced from one another at a substantial distance and are secured by their outer peripheries one to the frame and the other to the base, an elongate member extending in a generally vertical direction between the bushes, the lower end of the member being attached to the bush secured to the base and the upper end of the member being attached to the bush secured to the frame, whereby the bushes can deform in shear to accommodate large vertical components of vibration and whereby the elongate member acts as a lever extending between the bushes to permit the absorption of large movement of the frame relative to the base with the bushes being subjected to only relatively small deflections, each bushing having a bore in which the respective end of the corresponding member is secured and the bore of the bushing being of uniform cross-section and being bonded to a cylindrical sleeve, the elongate member passing through and being secured in the sleeve.

Claim 3
Dependent Claim
23 words
A vibratory apparatus as claimed in claim 1 wherein means are provided to vibrate the vibratory frame horizontally, vertically or a combination thereof.
Claim 4
Dependent Claim
38 words
A vibratory apparatus as claimed in claim 1 wherein means for vibrating the vibratory frame comprise at least one out-of-balance weight mounted for rotation on the vibratory frame, there being means to rotate the or each out-of-balance weight.
Claim 5
Dependent Claim
25 words
A vibratory apparatus as claimed in claim 3 wherein the means for vibrating the vibratory frame are located within the periphery of the vibratory frame.
Claim 6
Dependent Claim
31 words
A vibratory apparatus as claimed in claim 1 wherein three or more mounting devices are provided and are arranged in a spaced apart relationship around the periphery of the vibratory frame.
Claim 7
Dependent Claim
222 words
A vibratory apparatus comprising a base, a vibratory frame superimposed on the base, and means for mounting the frame on the base for vibration with respect thereto, which means is provided by a plurality of mounting devices each located between the frame and the base, and comprising a pair of opposed elastomeric bushes which are spaced from one another at a substantial distance and are secured by their outer peripheries one to the frame and the other to the base, an elongate member extending in a generally vertical direction between the bushes, the lower end of the member being attached to the bush secured to the base and the upper end of the member being attached to the bush secured to the frame, whereby the bushes can deform in shear to accommodate large vertical components of vibration and whereby the elongate member acts as a lever extending between the bushes to permit the absorption of large movement of the frame relative to the base with the bushes being subjected to only relatively small deflections, each bushing having a bore in which the respective end of the corresponding member is secured and the bore of each bushing being tapered, and a tapered sleeve being bonded to the bore of the bushing, the elongate member passing through and being secured in the tapered sleeve.
Claim 8
Dependent Claim
222 words
A vibratory apparatus comprising a base, a vibratory frame superimposed on the base, and means for mounting the frame on the base for vibration with respect thereto, which means is provided by a plurality of mounting devices each located between the frame and the base, and comprising a pair of opposed elastomeric bushes which are spaced from one another at a substantial distance and are secured by their outer peripheries one to the frame and the other to the base, an elongate member extending in a generally vertical direction between the bushes, the lower end of the member being attached to the bush secured to the base and the upper end of the member being attached to the bush secured to the frame, whereby the bushes can deform in shear to accommodate large vertical components of vibration and whereby the elongate member acts as a lever extending between the bushes to permit the absorption of large movement of the frame relative to the base with the bushes being subjected to only relatively small deflections, each bushing having a bore in which the respective end of the corresponding member is secured and the bore of each bushing being tapered, and a tapered sleeve being bonded to the bore of the bushing, the elongate member passing through and being secured in the tapered sleeve.
Claim 9
Dependent Claim
37 words
A vibratory apparatus as claimed in claim 6 wherein the tapered bores of the two bushings at opposed ends of the elongate member are arranged to taper inwardly towards the adjacent free end of the associated member.
