Lamp mounting for a material-handling tractor

Claim 2

In a tractor-mounted material-handling bucket apparatus of the type including a tractor and a boom pivotally mounted on the tractor for up and down pivotal movement and a bucket pivotally supported by said boom and being movable between a lowered loading position and a raised dumping position, the improvement comprising a lamp mounting member movably connected with said boom for movement in response to and according to pivotal movement of said boom, an alignment member connected with said lamp mounting member for moving said lamp mounting member relative to said boom and thereby align said lamp mounting member according to but different from the various up and down pivoted positions of said boom on said tractor, and a lamp attached to said lamp mounting member for illuminating toward said bucket.

Claim 3

The tractor-mounted material-handling bucket apparatus as claimed in claim 1, wherein said lamp mounting member is pivotally mounted on said boom.

Claim 4

The tractor-mounted material-handling bucket apparatus as claimed in claim 2, wherein said alignment member is a link pivotally connected with both said tractor and said lamp mounting member.

Claim 5

The tractor-mounted material-handling bucket apparatus as claimed in claim 2, wherein said lamp mounting member has a portion extending away from the location of the pivot mounting on said boom, and said lamp being a sealed beam type of lamp and adjustably mounted on said portion whereby the beam from said lamp can be directed to the upper portion of said bucket, when said boom is in its lowered pivotal position, and to the lower portion of said bucket, when said boom is in its raised pivotal position.

Claim 6

The tractor-mounted material-handling bucket apparatus as claimed in claim 1, including an additional said lamp on said lamp mounting member, the two said lamps bieng of the sealed beam type and mounted adjacent each other with the axis of their beams being parallel to each other, one of said lamps being a flood type of lamp and the other of said lamps being a vehicle headlight type of lamp, and with said one lamp having an overall angle of its beam greater than that of said other lamp.

Claim 7

The tractor-mounted material-handling bucket apparatus as claimed in claim 1, wherein said lamp mounting member is pivotally mounted on said boom and has a portion extending away from the location of the pivotal mounting, said lamp being attached to said lamp mounting member on said portion thereof and being of a beam type oriented with said beam being directed substantially horizontally in the pivotally lowered position of said boom, and said alignment member being a link pivotally connected with both said tractor and said lamp mounting member and being of a length between its said pivotal connections and being pivotally connected at locations relative to the pivotal mounting of said boom on said tractor and of said lamp mounting member on said boom to have said lamp mounting member remain substantially in its same vertical orientation throughout the pivoting of said boom, whereby said beam is again directed substantially horizontally in the pivotally raised position of said boom.

Claim 8

The tractor-mounted material-handling bucket apparatus as claimed in claim 6, including an additional said lamp mounted on said lamp mounting member, both said lamps being of the sealed beam type, and with one thereof having a beam of an angle greater than that of the other.

Claim 9

The tractor-mounted material-handling bucket apparatus as claimed in claim 1, wherein said lamp mounting member is pivotally mounted on said boom and is pivotally connected with said alignment member in a manner to render said lamp mounting member in the nature of a bellcrank.
