摘要：The apparatus (20) is for projecting and marking circular arcs and has a chassis (19) with tires (1) together with a rotatable axle (2) securable in an arbitrary position. It has a radius scale (13) on which the rotary position of the axle can be indicated, thereby allowing the radius of an arc over which the apparatus travels to be adjusted. The apparatus has a running meter, with which the length of an arc over which the apparatus travels to be mesaured. The apparatus has a pendulous axle (15), with which ground unevenness is compensated. It also has two guide bars (10,11) with which at the commencement of an arc to be travelled it is alignable in the arc tangents.
