Abstract
323,120. Simonsen, R. F. Jan. 1, 1929. Drilling.-A drill-stand for use in drilling holes in girders, rails, &c. by means of hand, fluidpressure or other portable machines comprises two rigid frames composed of four U-shaped members 1 of channel section united in pairs by channel members 6 and screwed rods 3 surrounded by distance pieces 4, and hinged together at the top by a rod 2. The lower ends of the frames are drawn together to grip the flange of a girder 8 by means of screwed rods 9 and nuts or keys 11, the opposite ends of the rods being squared to prevent rotation in the members 1. Rollers 10 are rotatably mounted on the rods 9 to facilitate movement of the stand along the girder and the lower ends 7 of the members 1 are splayed out to press the flange of the girder against the rollers when being gripped. The stand may be used on two channel girders or two angle bars placed back to back, and several stands may be used simultaneously or several drills may be used with one stand.
