<p>PCT No. PCT/AU88/00499 Sec. 371 Date Jun. 20, 1990 Sec. 102(e) Date Jun. 20, 1990 PCT Filed Dec. 23, 1988 PCT Pub. No. WO89/05714 PCT Pub. Date Jun. 29, 1989.A portable machine tool device (1) which may be transported in knocked down form in a substantially flat case. In assembled form the device (1) includes a support frame (8) and a swinging parallelogram linkage frame (9) which pivots about a rear edge of the support frame (8) and can be locked in any radial orientation by clamp (20) at the front edge of the support frame (8). The front edge of the support frame (8) includes a rectangular protractor scale (28) which reads off the radial angle of the frame (9) relative to the central position of the support frame (8). A machine tool is secured and independently locked or allowed to slide longitudinally and transversely in a carriage (38) which itself can longitudinally slide along or be locked to the upper rails (31) or the frame (9). The frame (9) itself can be rigidly locked to or slide at a constant radial direction, relative to the support frame (8). The height of the machine tool held in holder (38) above the support frame (8) is controlled by turning handle (35) connected to threaded bar (34) so as to alter the angle of the end plate (33) relative to the lower rails (30) of the frame (9).</p> |
