711,923. Uniting by fusion. YATES, H. Dec. 12, 1952 [Jan. 21, 1952], No. 1651/52. Class 83 (4). [Also in Group XXX] In a device for rotating and tilting objects, e.g. during welding, having a rotatable table mounted on a support tiltable about a. horizontal axis, a lever arm substantially parallel with and beneath the table and fixed to the support is pivotally connected by a rod to a trolley displaceabte by a' hut andscrew device along a guide inclined from beneath the table upwardly in the opposite direction to that in which the lever arm extends when the table - is horizontal. A rotatable table a on which a workpiece may be secured is supported in a Babbitt metal bearing b welded to levers c, /, which form an arm located between upstanding' plates d and pivoted on a horizontal shaft e journalled in the plates. A rod i is pivoted to the levers c and to a lug j<SP>1</SP> on a trolley. j movable along an inclined guide m formed by two spaced apart channel sections welded together and positioned between the plates d. Rollers j<SP>2</SP> on the trol!ey engage the opposed flanges of the channels and a nut k on the trollev is engaged by a screw I between the channels 'rotated by a wheel o, Rotation of the wheel o, moves the trolley in the guide and through the rod i the table is tilted about the shaft e. A motor p drives the table a through a belt q, worm, pinion s and spur wheel t. Channels g, g' welded to the plates d form feet for the device. A ball bearing may replace the Babbitt metal bearing.
