Abstract
Abstract A vacuum apparatus for debris collection comprises a motor vehicle having a vacuum tank collector and means for generating a vacuum. A horizontally and vertically extendible tube is connected to the vacuum tank collector, and extendible support linkage supports the tube along its length. Means are provided for extending and retracting the support linkage and the tube with respect to the vehicle and the ground while pivoting the tube and support linkage on a support base member pivotally mounted on the vehicle to provide a wide range of motion over the ground surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
The combination with a motor vehicle for collecting debris having a vacuum tank collector and means for generating a vacuum therein comprising a platform member mounted on the front of said motor vehicle for pivotal movement in a vertical plane, first means for producing pivotal motion in said platform member, a support base member mounted on said motor vehicle for pivotal movement in a horizontal plane, second means for producing pivotal motion in said support base member, an extendible tube having one end coupled to the vacuum tank collector and the other end adapted to be moved along the surface of the ground, support linkage for supporting said tube along its length, one end of said support linkage being coupled to said support base member, third means having one end coupled to said support base member and the other end coupled to said support linkage for extending and retracting said support linkage with respect to said support base member, thereby causing said tube to be extended or retracted, whereby said tube is extendible and retractable along its longitudinal axis and pivotal in both horizontal and vertical planes.
Claim 2
Dependent Claim
187 words
The combination with a motor vehicle for collecting debris having a vacuum tank collector and means for generating a vacuum therein comprising a platform member mounted on the front of said motor vehicle for pivotal movement in a vertical plane, first means for producing pivotal motion in said platform member, a support base member mounted on said motor vehicle for pivotal movement in a horizontal plane, second means for producing pivotal motion in said support base member, an extendible tube having one end coupled to the vacuum tank collector and the other end adapted to be moved along the surface of the ground, support linkage for supporting said tube along its length, one end of said support linkage being coupled to said support base member, third means having one end coupled to said support base member and the other end coupled to said support linkage for extending and retracting said support linkage with respect to said support base member, thereby causing said tube to be extended or retracted, whereby said tube is extendible and retractable along its longitudinal axis and pivotal in both horizontal and vertical planes.
Claim 3
Dependent Claim
60 words
The combination according to claim 1 wherein said support linkage comprises a horizontal section and a vertical section, fourth means for extending and retracting said vertical section toward and away from the ground, whereby said tube is capable of both horizontal and vertical movement to provide a wide range of motion in movement of the tube over the ground surface.
Claim 4
Dependent Claim
38 words
The combination according to claim 2 wherein said first, second, third, and fourth means comprise double-acting, fluid-operated cylinders, and control means for selectively operating said fluid cylinder to produce the desired controlled motion for the collection of debris.
