Abstract
Abstract An aerial platform is carried on an extensible boom which is mounted on a motor vehicle for swinging movement in horizontal and vertical planes: the platform is of rectangular planform, and is mounted for swinging movement through 180* on a vertical axis adjacent the end of the boom so as to be adjacent either side of the boom. The boom terminates with a connector, pivoted to the end of the boom fly section on a horizontal axis. At its free end, the connector has a vertical semi-cylindrical housing, in which is a rotary hydraulic motor. A platform support is fastened to the rotary motor and supports the platform outwardly of the semi-cylindrical end of the connector for movement by the motor through 180*, so that it may be positioned adjacent either side of the boom.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
234 words
Aerial platform apparatus comprising: a. a vehicle, b. a linearly extensible and retractable boom having a length when extended substantially greater than the length thereof when retracted, c. means mounting said boom on said vehicle for swinging movement in vertical and horizontal planes, d. means for extending, retracting and swinging said boom, e. load support means having a neutral position in which an axis thereof is in line with the boom axis, and f. means at the free end of said boom for supporting said load support means for pivotal movement between two positions in each of which the rear portion of the load support means is substantially adjacent a side of the boom and in each of which said positions said load support means axis is substantially perpendicular to the boom axis, g. whereby the portion of the load support means opposite said rear portion has access to an extensive area of a wall without movement of the vehicle by positioning said opposite portion near a wall with the rear portion adjacent a side of said boom and said boom extended, then swinging said boom and said load support means and retracting said boom, and after the boom reaches a plane perpendicular to said wall, continuing to swing said boom and said load support means until the rear portion of the load support means is substantially adjacent the opposite side of said boom.
Claim 2
Dependent Claim
234 words
Aerial platform apparatus comprising: a. a vehicle, b. a linearly extensible and retractable boom having a length when extended substantially greater than the length thereof when retracted, c. means mounting said boom on said vehicle for swinging movement in vertical and horizontal planes, d. means for extending, retracting and swinging said boom, e. load support means having a neutral position in which an axis thereof is in line with the boom axis, and f. means at the free end of said boom for supporting said load support means for pivotal movement between two positions in each of which the rear portion of the load support means is substantially adjacent a side of the boom and in each of which said positions said load support means axis is substantially perpendicular to the boom axis, g. whereby the portion of the load support means opposite said rear portion has access to an extensive area of a wall without movement of the vehicle by positioning said opposite portion near a wall with the rear portion adjacent a side of said boom and said boom extended, then swinging said boom and said load support means and retracting said boom, and after the boom reaches a plane perpendicular to said wall, continuing to swing said boom and said load support means until the rear portion of the load support means is substantially adjacent the opposite side of said boom.
Claim 3
Dependent Claim
25 words
The aerial platform apparatus of claim 1, said last mentioned means comprising means for supporting said load support means for rotary movement through substantially 180*.
Claim 4
Dependent Claim
34 words
The aerial platform apparatus of claim 1, said boom at the free end thereof comprising a semi-cylindrical housing having a diameter at least equal to the width of the boom at the end thereof.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
43 words
The aerial platform apparatus of claim 4, and a support connected to a said part of said rotary motor and supporting said load support means, a shaft extending axially downwardly from said housing, and said support comprising an arm journalled on said shaft.
Claim 7
Dependent Claim
29 words
The aerial platform apparatus of claim 1, wherein said load support means comprises an aerial platform having a floor and wall means, said floor having a substantially rectangular platform.
Claim 8
Dependent Claim
22 words
The aerial platform apparatus of claim 6, wherein a long side of said platform is adjacent the free end of said boom.
Claim 9
Dependent Claim
30 words
The aerial platform apparatus of claim 1, wherein said means for supporting said load support means comprises connector means pivotally connected to said boom for movement in a vertical plane.
Claim 10
Dependent Claim
28 words
The aerial platform apparatus of claim 8, and means for rotating said connector means simultaneously, equally and oppositely to swinging movement of said boom in a vertical plane.
Claim 11
Dependent Claim
35 words
The aerial platform apparatus of claim 8, said connector means outwardly of the pivotal connection thereof comprising a vertically extending housing, and rotary motor means carried by said housing for rotating said load support means.
Claim 12
Dependent Claim

Claim 13
Dependent Claim
200 words
In an aerial platform apparatus comprising a vehicle having a linearly extensible and retrActable boom having and extended length substantially greater than the retracted length mounted on said vehicle for horizontal swinging and vertical luffing movements, and a platform carried at the end of said boom, the improvement comprising means mounting said platform for horizontal movement between two positions in each of which the rear of the platform is substantially adjacent a side of said boom and in each of which an axis of said platform which is in alignment with the boom axis in the neutral position of the platform is substantially perpendicular to the boom axis, whereby the portion of the platform opposite siad rear portion has access to an extensive area of a wall without movement of the vehicle by positioning said opposite portion near a wall with the rear portion adjacent a side of said boom and said boom extended, then swinging said boom and said platform and retracting said boom, and after the boom reaches a plane perpendicular to said wall, continuing to swing said boom and said platform until the rear portion of the platform is substantially adjacent the opposite side of said boom.
Claim 14
Dependent Claim
200 words
In an aerial platform apparatus comprising a vehicle having a linearly extensible and retrActable boom having and extended length substantially greater than the retracted length mounted on said vehicle for horizontal swinging and vertical luffing movements, and a platform carried at the end of said boom, the improvement comprising means mounting said platform for horizontal movement between two positions in each of which the rear of the platform is substantially adjacent a side of said boom and in each of which an axis of said platform which is in alignment with the boom axis in the neutral position of the platform is substantially perpendicular to the boom axis, whereby the portion of the platform opposite siad rear portion has access to an extensive area of a wall without movement of the vehicle by positioning said opposite portion near a wall with the rear portion adjacent a side of said boom and said boom extended, then swinging said boom and said platform and retracting said boom, and after the boom reaches a plane perpendicular to said wall, continuing to swing said boom and said platform until the rear portion of the platform is substantially adjacent the opposite side of said boom.
