Abstract

A support device includes a bracket secured on a base for rotatably supporting a roller and for engaging with and for supporting a work piece. A stick is secured in the base and has an orifice for slidably engaging with a rod which is extended downward from the bracket for allowing the bracket to be adjusted to a suitable height. The bracket includes a pair of blocks for slidably receiving a pair of poles. The poles each includes an extension extended upward for engaging with the work piece and for preventing the work piece from moving laterally.

Claims

1. A support device for a work piece, said support device comprising:

a base including a stick having an orifice formed therein,

a bracket secured on said base including a rod extended downward and slidably engaged in said orifice of said stick,

means for securing said rod to said stick, and

a roller rotatably supported in the bracket for engaging with and for supporting the work piece,

said base including a pair of beams, a pair of frames having an upper portion pivotally coupled to said beams, and a pair of bars secured between said frames, said stick being secured between said bars.

2. The support device according to claim 1, wherein a first of said beams includes a bolt, said base includes a first plate secured on one end of said beams and includes a second plate threadedly engaged with said bolt, and means for rotating said bolt and for moving said second plate toward and away from said first plate.

3. The support device according to claim 1, wherein said bracket includes a pair of flanges extended upward, said roller includes two end caps and includes a shaft having two ends rotatably supported in said flanges, said shaft includes two stops and two springs biased between said end caps and said stops for allowing said ends of said shaft to be moved inward of said roller against said springs.

4. A support device for a work piece, said support device comprising:

a base,

a bracket secured on said base, said bracket including a pair of blocks, a pair of poles slidably engaged in said blocks and each having an extension extended upward for engaging with the work piece and for preventing the work piece from moving laterally, and means for securing said poles to said blocks, and
