Abstract
Abstract Apparatus to service an unusually high light pole is disclosed. The lights on the pole are supported by a ring having latches capable of engaging support members at the top of the pole. The lights are lowered by moving a retriever ring up the pole to disengage the latches and carry the support ring to the bottom. Motive power is supplied by an electric motor which is connected to the retriever ring by three steel cables traveling up the inside of the pole and over pulleys at the top of the pole.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
Apparatus of the class described comprising in combination: a pole having outwardly extending support members generally at the top thereof; light supporting means adapted to support a plurality of lights; a first electrical connector on said light supporting means adapted to engage detachably a second electrical connector on one of said outwardly extending members; latching means on said light supporting means operable to engage said outwardly extending support members; carrier means adapted to ride on said pole and carry said light supporting means up and down the pole said carrier means having a release means thereon operable to disengage said latching means; and moving means operable to move said carrier means up and down said pole.
Claim 2
Dependent Claim
116 words
Apparatus of the class described comprising in combination: a pole having outwardly extending support members generally at the top thereof; light supporting means adapted to support a plurality of lights; a first electrical connector on said light supporting means adapted to engage detachably a second electrical connector on one of said outwardly extending members; latching means on said light supporting means operable to engage said outwardly extending support members; carrier means adapted to ride on said pole and carry said light supporting means up and down the pole said carrier means having a release means thereon operable to disengage said latching means; and moving means operable to move said carrier means up and down said pole.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 in which said light supporting means comprises an annular member generally surrounding said pole.
Claim 4
Dependent Claim
32 words
The apparatus of claim 2 in which said latching means comprises pivoting latch members adapted to slide above striker bars mounted on said outwardly extending members as a result of pivoting movement.
Claim 5
Dependent Claim
90 words
The apparatus of claim 3 in which said carrier means comprises an annular member generally surrounding said pole with said release means comprising upwardly extending rotatable release pins each having a laterally extending member at its upper end, whereby said laterally extending member will engage said pivoting latch members when said pins are rotated to a first position to permit unlatching of said light supporting means from said extending support members, but will clear said pivoting latch members when said pins are rotated to a second position to permit relatching.
Claim 6
Dependent Claim
40 words
The apparatus of claim 4 in which said moving means is connected to said annular carrier by a plurality of cables extending from said moving means through said pole, over pulleys in said outwardly extending members, and to said carrier.
Claim 7
Dependent Claim
27 words
The apparatus of claim 5 in which said cables are connected to said carrier through springs adapted to compensate for differences in the lengths of the cables.
Claim 8
Dependent Claim
31 words
The apparatus of claim 6 including compressive spring means between said light supporting means and said outwardly extending support members which operate to insure a tight engagement by said latch members.
Claim 9
Dependent Claim
32 words
The apparatus of claim 7 in which said first connector on said light supporting means comprises a male type plug adapted to engage said second connector which comprises a female type plug.
Claim 10
Dependent Claim
26 words
The apparatus of claim 8 including connecting means between said release pins so that all pins may be simultaneously rotated between said first and second positions.
